Introduction
A traditional London broil is made with thin slices of beef seared under intense oven heat. It is similar to steak frites in flavor and texture, but the entire cooking process happens under your oven broiler. If you are searching for How to Make London Broil Oven?, the essential ingredients are simple: good beef, oil, salt, pepper, a broiler-safe pan, and a little time.
The most common version uses flank steak, sliced across the grain so it stays tender. You can also use top round, sirloin, or another thin steak. The finished meat is browned outside, juicy in the center, and especially satisfying with a pan gravy made from its drippings.
Broiling cooks quickly and leaves almost no cleanup, but the difference between juicy beef and dry, chewy beef is often just a few minutes. Learn how to position the meat, adjust the broiler, watch the browning, and confirm doneness before you start.

What Is London Broil?
London broil is an American dish that uses direct, high heat to brown thin slices of beef. Historically, the dish was prepared under a restaurant broiler and served with potatoes and a savory gravy. A home oven broiler makes the same style of food without a grill or frying pan.
The defining characteristics are hot, fast cooking, well-browned edges, and meat sliced thin enough to remain tender. The name comes from the broiling process rather than a special London sauce. Some cooks add Worcestershire sauce, mustard, or garlic to the beef, but a classic version often uses nothing more than salt, pepper, and a little oil.
Unlike a slow oven roast, London broil does not cook the beef gradually. The broiler is close to the food, so browning begins immediately. This produces a steakhouse-like crust and keeps the cooking time short, but the meat must be watched closely from the first minute.
Choosing the Best Cut of Beef
Flank steak is the most popular choice because it is affordable, flavorful, and naturally tender when cut across the grain. Ask the butcher for a flank steak sliced to about one-half inch thick. If you are slicing it yourself, place the steak flat and cut perpendicular to the long muscle fibers.
Top round is another dependable option. It has a milder flavor and is leaner than flank, so it should not be overcooked. Sirloin steak or steak tips also work, although they may cost more and can vary considerably in tenderness depending on the section used.
For the most reliable result, choose pieces with a fairly uniform thickness. Meat that is very thin at one end and thick at the other will brown unevenly. Thick, premium dry-aged steaks can be broiled, but the cooking time will be longer and the total energy use may increase. Traditional London broil is designed around thinner cuts.
Plan on about three to four ounces of raw beef per serving. One and a half pounds will feed four people as the main part of a meal, especially when served with potatoes, vegetables, bread, and gravy.
Equipment and Oven Preparation
You need a metal pan that the oven manufacturer considers safe for broiling. A heavy cast-iron skillet, rimmed baking sheet, or quality broiler pan is suitable. Avoid glass, ceramic, plastic, or lightweight cookware that could crack or warp.
Position the oven rack about four to six inches below the broiler element. On a compact oven, the correct distance may be smaller, so begin with the manufacturer’s recommended setting. If possible, set the rack before preheating so you do not handle a hot pan while adjusting it.
Set the oven to high broil. Gas broilers heat rapidly, while electric broilers may need several minutes to reach full intensity. Refer to the oven manual if it offers a broil setting with temperature control, such as high, medium-high, or low.
Have an instant-read thermometer, long oven mitts, and a pair of tongs nearby. Useful tools also include a sharp cutting board, a sharp knife, a small bowl for seasoning, and a spoon for testing the gravy.
Seasoning the Beef
A simple seasoning blend is all traditional London broil needs. Sprinkle the beef generously with kosher salt and freshly ground black pepper. If you prefer garlic, add one teaspoon of garlic powder, or rub a cut clove over the surface of each slice.
Finely minced onion, smoked paprika, black peppercorns, or a small amount of Worcestershire sauce can provide extra flavor. Keep savory herbs such as rosemary and thyme restrained because strong flavors may compete with the browned crust.
Rub each piece with a thin coating of neutral oil. Oil promotes browning and helps the seasoning adhere without creating a heavy, salty crust. A brief marinade of 15 to 30 minutes is sufficient. If using a marinade with vinegar or citrus, keep the time short because acid can change the texture of thin beef.
Step-by-Step London Broil Recipe
Ingredients
- 1 and a half pounds flank steak, sliced one-half inch thick across the grain
- 2 tablespoons neutral cooking oil
- Kosher salt
- Freshly ground black pepper
- 1 teaspoon garlic powder, optional
- 1 teaspoon Worcestershire sauce, optional
- 2 to 3 tablespoons unsalted beef stock, for gravy
- 1 tablespoon all-purpose flour, for thickening
- Small handful of chopped fresh parsley, optional
Cooking Directions
- Preheat the broiler. Set the oven to high broil and place the rack four to six inches below the element. Position it before preheating if your oven rack can be adjusted safely. Let the broiler reach full heat for about five minutes.
- Prepare the beef. If the flank steak is thicker than one-half inch, slice it across the grain into thin, evenly cut strips. Trim away large pockets of hard fat, but leave a thin layer of fat where possible because it contributes flavor.
- Dry and season. Pat the meat with paper towels. Rub it with the oil, salt, pepper, garlic powder, and Worcestershire sauce. Arrange the pieces on a plate or tray for 15 to 30 minutes while the oven finishes preheating.
- Prepare the pan. Place the broiler-safe pan inside the oven to heat with the element, about one to two minutes before adding the beef. A preheated surface promotes a good sear. Make sure the pan does not touch the broiler element.
- Arrange the meat. Carefully lay the seasoned beef on the hot pan. Leave about one inch of space between pieces. Crowding traps steam, while generous spacing allows the radiant heat to brown each slice.
- Start broiling. Cook the beef without opening the oven door for the first three to four minutes. Depending on thickness and broiler intensity, it will probably need approximately four to eight minutes in total. Keep the oven door slightly open if your oven manual recommends doing so.
- Monitor the surface. Watch the beef through the oven window. It should develop a deep brown crust while the center remains pink. If the pan is farther from the element and the meat is not browning, move the rack closer after checking the oven manual.
- Turn only if needed. Pieces of one-half-inch beef usually brown very quickly on the side facing the broiler and do not require flipping. If the underside remains pale or the rack is lower than usual, use tongs to turn the pieces carefully.
- Check the center. Use an instant-read thermometer to check several thick pieces. For the safest temperature, beef should reach 145 degrees Fahrenheit, measured in the thickest part. Pull the meat as soon as it reaches the desired doneness because residual heat will continue cooking it.
- Rest before slicing. Transfer the beef to a clean plate and let it rest for three to five minutes. The pause allows the juices to settle, making each slice more flavorful and easier to serve.
- Make the gravy. Leave the pan in the turned-off, cooling oven for a few minutes so it does not scorch the drippings. Follow the gravy method below to create a simple sauce from the browned beef juices.
Checking Doneness Safely
Color is only a rough guide to steak doneness. A meat thermometer gives a much more reliable result. Aim the probe horizontally into the thickest portion of a piece of meat, away from the pan, bone, fat, and heavily browned exterior.
For food safety, whole cuts of beef should reach an internal temperature of at least 145 degrees Fahrenheit. Some traditional London broil recipes serve the beef more well-done, but many home cooks prefer it slightly less cooked for tenderness. Because flank steak is lean, it is especially important not to let it continue broiling after reaching the desired temperature.
With thin pieces, it is difficult to take an accurate reading without cooking through the steak. Check near the center, compare the temperature with several pieces, and avoid probing the same opening repeatedly. If the thermometer cannot fit without piercing a tiny slice, test the thickest piece first.
Making Easy Pan Gravy
The browned drippings contain enough fat and flavorful particles to make a fast, rich gravy. Return the broiler pan to the switched-off oven or place it on a heatproof surface. Carefully pour off any liquid, leaving about one tablespoon of fat and all the browned bits in the pan.
Whisk one tablespoon of all-purpose flour into the remaining fat. Cook it for about 30 seconds, stirring, before slowly adding two to three tablespoons of warm beef stock. The mixture will thicken quickly and should be whisked to prevent lumps.
Once the gravy begins to bubble, add more stock one tablespoon at a time until it reaches the consistency you prefer. Season with salt, pepper, Worcestershire sauce, or a splash of meat drippings. It should be slightly thicker than cream when served. Keep it warm over very low heat, but do not let it boil hard or leave it unattended.
If you do not have drippings, melt one tablespoon of butter in a small saucepan, stir in the flour, and prepare the gravy with stock. This is less flavorful than a drippings-based version, but it still complements the beef well.
Serving and Pairing Ideas
London broil is traditionally served with sliced or fried potatoes, but the recipe works with many sides. Try roasted baby potatoes, French fries, garlic mashed potatoes, or crisp oven-roasted potatoes. A green salad balances the rich gravy and browned meat.
Other useful side dishes include roasted broccoli, green beans, grilled zucchini, sautéed spinach, or a mixture of roasted seasonal vegetables. Crusty bread is helpful for soaking up the pan juices.
For a simple presentation, arrange the sliced beef on a warm platter, spoon the gravy over the top, and finish with chopped parsley. Place the gravy in a small serving pitcher as well so each person can add extra sauce individually.
Comparison of Popular Beef Cuts
| Beef cut | Flavor and texture | Best preparation | Broiling notes |
|---|---|---|---|
| Flank steak | Rich beef flavor; tender when sliced correctly | Slice one-half inch thick across the grain | Classic choice; usually takes about 4 to 7 minutes |
| Top round | Lean, mild, and reasonably tender | Slice thinly across the grain | Watch closely because the lean meat can dry out |
| Sirloin steak | Balanced flavor with a tender interior and browned edge | Choose pieces cut to an even thickness | Thin portions cook quickly; thicker portions may take longer |
| Skirt steak | Rich flavor with softer fat along the edge | Trim excess hard fat, leaving a little for flavor | Fat may brown quickly, so monitor the pan closely |
| Strip steak | Juicy, robust, and often slightly more tender | Slice to one-half inch or follow package thickness | Good choice for first-time broilers |
Tips and Best Practices
- Slice against the grain. This is the most important step for tender flank. Short muscle fibers make the finished slices easier to chew.
- Keep pieces evenly thick. Thin slices require less cooking time and give you more control over the final result.
- Leave space between pieces. The beef needs direct exposure to the broiler for browning rather than steaming.
- Do not walk away. A broiler can go from well browned to burned in less than a minute.
- Use the oven window. Checking through the window prevents the heat loss caused by opening the door.
- Protect thin parts with foil. If one end of a steak is much thinner, loosely cover that area with foil to slow its browning. Keep foil safely below the heating element.
- Rest the meat. A three- to five-minute rest makes sliced beef noticeably more succulent.
- Warm the serving plates. This is optional, but it helps the beef and gravy stay hot longer.
- Follow the oven manual. Broiler wattage and rack positions vary significantly among ovens.
Common Mistakes and How to Fix Them
Placing the rack too far from the broiler is one of the most common problems. The meat may cook slowly without developing a browned surface, and the center can become dry before the outside gains color. If the pan has never been broiled, use the oven manual to determine the recommended distance.
Crowding the pan traps moisture and creates steam. Leave approximately one inch between pieces, or broil the beef in two batches. A large surface area allows radiant heat to reach every slice.
Leaving the drippings unattended can cause them to smoke or burn, especially in a dark metal pan. Watch the beef during the final two minutes. If the pan or drippings appear close to scorching, remove the beef and adjust the cooking process before making the gravy.
Overcooking thin flank steak makes it tough. Many pieces reach the desired temperature in only a few minutes under a full broiler. Begin checking early and pull the beef while the center is still juicy.
Cutting with the grain produces tough slices even when the meat was not overcooked. Look at the steak before slicing and cut across the visible fibers rather than lengthwise.
Using an open oven door for the entire cooking time can expose the cook and surrounding area to intense heat. Use the door only as directed by the oven manual, generally for starting the broil or checking the food, and keep the proper distance from the hot surface.
Preparing the gravy in an extremely hot pan can burn the drippings before the flour and stock are added. Remove the pan from the hot oven and let it cool briefly before deglazing.
Using a glass or non-broiler-safe pan creates a serious risk of shattering. Confirm that the cookware is oven-safe and suitable for intense direct heat before heating it.
Easy Recipe Variations
The basic oven-broiling method works well with other thin meats. For chicken, use boneless, skinless breasts cut to an even thickness. Season with salt, pepper, and paprika, then broil until browned and cooked to an internal temperature of 165 degrees Fahrenheit.
Thin pork chops or slices of pork tenderloin can also be broiled. Cook whole cuts to at least 145 degrees Fahrenheit and use a thermometer because they can remain pink even after reaching a safe temperature.
For a sweeter variation, combine Worcestershire sauce with a small amount of brown sugar, garlic powder, and smoked paprika. Brush the mixture over the beef during the final two minutes of cooking. Watch the glaze closely because sugar darkens quickly under a broiler.
You can change the gravy profile by using low-sodium beef stock and adding sliced mushrooms, chopped onions, or a small splash of red wine. Simmer the additions before thickening the sauce so their flavors blend.
To create a complete sheet-pan meal, place thinly sliced potatoes and vegetables on the broiler pan first, cook them briefly under the broiler, and then add the beef for the final stage. The drippings can still be used for a quick gravy, although watching the vegetables may require a lower broil setting or slightly more total cooking time.
Frequently Asked Questions
What temperature should I use for London broil?
Set the oven to high broil, usually around 450 degrees Fahrenheit. The setting controls the top heating element rather than maintaining a consistent oven-cavity temperature like a conventional bake. If your oven offers a temperature-controlled broiler, high is the usual choice for a browned exterior.
How long does beef take under an oven broiler?
One-half-inch slices generally need about four to eight minutes, depending on the cut, thickness, broiler intensity, and distance from the element. Start checking after four minutes. Keep the oven door closed while the first stage of cooking occurs, then use a thermometer to determine doneness.
Can I make London broil in a toaster oven?
Yes, if the appliance has a functioning broil function and the manufacturer permits broiler-safe cookware. Follow its recommended rack position, which may differ from a full-size oven. Begin with a shorter cooking time because compact appliances can broil very aggressively.
Can I broil London broil in a cast-iron skillet?
A cast-iron skillet works well because it heats quickly and creates good browning. Make sure the skillet is intended for oven use, does not exceed the oven’s weight limits, and cannot fit into the oven with its handle too close to the broiler element. Use a mitt rated for high heat when removing it.
What if my oven does not have a broil setting?
Place the beef on an upper oven rack and bake at the oven’s highest temperature until browned. This method is less intense than a true broiler and usually takes longer. You can briefly brown the beef in a hot skillet first, then transfer it to the oven to finish cooking.
Can I prepare London broil ahead of time?
You can slice and season the beef up to 24 hours ahead. Cover the tray and refrigerate it. A short oil-and-herb marinade works well overnight, but acidic marinades can change the surface over time. Take the beef out of the refrigerator shortly before broiling so it does not remain cold in the center.
Can I make gravy without beef drippings?
Yes. Melt butter in a small saucepan, whisk in flour, and gradually add beef stock until the desired thickness is reached. If you are making the gravy from the broiler pan, a little pan drippings still adds superior flavor, but this shortcut works when there are none available.
Conclusion
The answer to How to Make London Broil Oven? is simpler than it may seem: preheat a full broiler, choose evenly cut beef, season it, give each piece room, and watch it closely. Flank steak sliced across the grain is the classic choice, while top round, sirloin, and skirt steak are also dependable alternatives.
A short broil, a quick temperature check, and a few minutes of resting time produce browned beef that remains juicy. Serving it with potatoes, vegetables, and gravy made from the pan drippings completes this traditional, crowd-pleasing dish. For consistently excellent results, keep the meat thin, avoid crowding the pan, and remember that the broiler can continue browning and cooking after the oven is switched off.
