London broil meat recipes turn a lean beef cut into juicy slices with a short marinade, high heat, and thin slicing across the grain.
London broil is less a single cut and more a smart way to cook lean beef. You marinate for flavor, cook hot for a dark crust, then slice thin so each bite stays tender. It’s the kind of dinner that feels like a steakhouse plate, even on a weeknight.
This article gives you a reliable base method plus several recipe paths you can mix and match. You’ll see which cuts work, how long to marinate, how to hit the doneness you want, and what to do with leftovers so nothing goes to waste.
What London Broil Means In The Kitchen
Many stores label a package “London broil,” yet the label often points to a cooking style. The classic approach uses a large, lean piece of beef cooked fast and sliced thin. Flank steak is common, and top round shows up a lot too.
Lean cuts bring bold beef flavor, then punish you if you treat them like a ribeye. The win comes from three moves: salt and acid in a marinade, a quick cook over high heat, and thin slices across the grain.
London Broil Meat Recipes With Quick Marinades
A good marinade does two jobs. It seasons the meat inside and out, and it helps the surface brown without drying out. You don’t need a long ingredient list. You need balance.
| Cut Often Sold As London Broil | Texture And Flavor Notes | Cook Route That Fits |
|---|---|---|
| Flank steak | Beefy, long grain, stays tender when sliced thin | Grill, broil, or cast-iron |
| Top round (London broil roast) | Lean, mild, benefits from a strong marinade | Broil or sear then oven-finish |
| Bottom round | Firm, lean, likes thin slices and extra rest time | Broil with close temp checks |
| Sirloin tip | Lean with a steak-like feel, can dry if overcooked | Grill or sear then quick finish |
| Tri-tip | Richer than round, two grain directions to slice across | Grill then rest longer |
| Skirt steak | Big flavor, thinner, cooks fast and needs close watch | Grill or cast-iron only |
| Chuck shoulder steak | More fat, softer chew, still likes thin slicing | Cast-iron sear then oven-finish |
| Flat iron | Tender for the price, takes marinades well | Grill or broil |
Marinade Ratios That Work
Use this structure, then swap flavors without guessing.
- Oil: 3 tablespoons per 1 1/2 pounds beef
- Acid: 1 1/2 tablespoons (vinegar, citrus, or wine)
- Salt: 1 1/4 teaspoons kosher salt
- Sweet: 1 to 2 teaspoons, optional
- Aromatics: garlic, onion, pepper, herbs, mustard, or soy sauce
If soy sauce is in the mix, cut back added salt.
Timing And Storage
For flank steak, marinate 2 to 6 hours. For round cuts, aim for 6 to 12 hours. Past 24 hours, the surface can turn soft.
Keep it chilled, sealed in a zip bag or covered dish. Want a sauce at the end? Save a clean portion before it touches raw meat.
Heat Plan That Gets A Good Crust
Pat the surface dry, get the heat high, then let the meat release before you flip. A stuck patch usually needs more time.
Broiler Method
Set an oven rack 4 to 6 inches from the broiler and heat it 8 minutes. Broil on a sheet pan.
- Pat the meat dry and brush with a thin film of oil.
- Broil 4 to 7 minutes per side, based on thickness.
- Check the temp early, then often.
Grill Method
Set up two zones: one hot for searing, one cooler for finishing.
- Oil the grates, not the meat, to cut sticking.
- Sear 3 to 5 minutes per side for flank steak.
- Move off direct heat to finish if the center lags behind.
Cast-Iron Sear And Oven Finish
Heat a cast-iron skillet until it smokes lightly. Sear 2 to 4 minutes per side. Finish in a 425°F oven if needed.
This works well for thicker cuts.
Doneness Targets And Rest Time
If you want medium-rare slices, pull the meat at 125°F to 130°F, then rest. For medium, pull at 135°F to 140°F. Whole cuts of beef reach a safe point at 145°F with a 3-minute rest, per the FSIS safe temperature chart.
Use a thermometer in the thickest part, away from fat and gristle. The FSIS food thermometer tips show placement basics for roasts and steaks.
Slice Like You Mean It
Slicing is not a garnish step. It’s the step that turns a chewy slab into tender bites. Rest the meat 8 to 12 minutes, then slice thin.
Find The Grain Fast
The grain is the direction the muscle fibers run. Slice across the lines, then go thin so each bite stays tender. If the grain shifts, split the piece and slice each section across its own grain.
Slice Thickness That Works
Aim for 1/8-inch slices. If you want a plated steak feel, go a touch thicker. If you want sandwich slices, go thinner and pile them high.

Recipe Balsamic Dijon Grilled London Broil
Balsamic brings tang and a glossy crust, while Dijon adds a sharp bite. It pairs well with roasted potatoes or a pile of arugula.
Ingredients
- 1 1/2 to 2 pounds flank steak or sirloin tip
- 3 tablespoons olive oil
- 2 tablespoons balsamic vinegar
- 1 tablespoon Dijon mustard
- 1 teaspoon kosher salt
- 1 teaspoon black pepper
- 1 teaspoon dried oregano

- Rest, slice thin, and spoon any juices over the slices.
| Flavor Route | What To Put In The Marinade | Side That Matches |
|---|---|---|
| Chili-lime | Lime juice, oil, salt, cumin, chili flakes | Charred corn, black beans, avocado |
| Steakhouse pepper | Cracked pepper, Worcestershire, garlic, butter finish | Mashed potatoes, green beans |
| Herb and lemon | Lemon zest, parsley, thyme, olive oil, salt | Roasted carrots, couscous |
| Korean-inspired | Soy sauce, ginger, garlic, pear or apple, sesame oil | Rice, quick pickled cucumbers |
| Smoky coffee rub | Espresso powder, paprika, brown sugar, salt, oil | Slaw, baked sweet potatoes |
| Red wine and rosemary | Red wine, rosemary, garlic, olive oil, salt | Roasted mushrooms, crusty bread |
| Garlic and mustard | Mustard, garlic, vinegar, oil, pepper | Potato salad, tomato slices |
Leftover Moves That Don’t Taste Like Leftovers
Cook a bigger piece on purpose and you’re set for a couple more meals. Cold slices stay tender when you keep them thin and add a sauce or dressing.
- Steak salad: toss greens with lemon, olive oil, and salt, then top with sliced beef and shaved Parmesan.
- Rice bowl: warm rice, add sliced beef, then add kimchi, cucumbers, and a soft egg.
- Sandwich stack: toast bread, smear mustard, pile beef, then add pickles and onions.
- Quick tacos: warm tortillas, add beef, then add salsa verde and chopped onions.
If you reheat, do it gently. A quick warm-up in a covered skillet over low heat keeps the slices from tightening up.
Fixes For Common London Broil Problems
London broil can go from tender to tough in one step. Here are the usual slip-ups and fast fixes.
Tough Chew
Slice thinner and make sure you cut across the grain. If the meat still fights you, pull it at a lower temp next time and rest longer.
Dry Slices
Lean beef dries fast once it crosses medium. Cook a touch less, then let carryover heat finish the center. A drizzle of pan juices or a spoon of olive oil helps on the plate.
Too Salty Marinade
Cut soy sauce in half and replace it with water or citrus next time. You can also skip added salt when the marinade already has salty ingredients.
Burning On The Surface
Sugar browns fast. Pat the surface drier, then sear. If you want sweetness, add a little honey after cooking as a glaze made from a clean, unused sauce.

When you plan the steps, London broil feels easy. Here’s a clean rhythm that works with most london broil meat recipes.
