Baking london broil in oven at high heat, resting it well, and slicing thin across the grain turns a lean cut into a tender roast.
London broil can feel tricky because the name hints at a single cut, yet it’s usually a method used on lean, wide steaks like top round or flank. In the oven, the win is control: steady heat, a clear target temperature, and fewer flare-ups than a grill. If you’ve ever pulled one out and found it chewy, the fix is almost always the same trio—don’t overcook it, don’t rush the rest, and don’t slice with the grain. This shows how to bake london broil in oven step by step.
A thermometer check beats guessing, and your knife work seals the deal at serving.
What You Need Before You Start
You don’t need special gear, though one tool pays for itself: an instant-read thermometer. London broil is lean, so a temperature miss can turn it firm. Plan on a rimmed sheet pan or roasting pan, a wire rack if you’ve got one, and a sharp knife for clean slices.
- London broil-style steak (top round, flank, or similar), 1 1/2 to 2 1/2 pounds
- Kosher salt and black pepper
- High-smoke-point oil (avocado, canola, grapeseed)
- Optional flavor helpers: garlic, smoked paprika, dried oregano, soy sauce, Worcestershire
London Broil Oven Time And Temperature By Thickness
Use the table as a starting point, then trust the thermometer. Times assume a 450°F (232°C) oven and meat starting near fridge-cold. If your steak starts closer to room temperature, it may finish a bit sooner.
| Thickness | Rough Bake Time At 450°F | Pull Temp |
|---|---|---|
| 3/4 inch | 8–10 minutes | 125°F (medium-rare) |
| 1 inch | 10–12 minutes | 125°F (medium-rare) |
| 1 1/4 inch | 12–15 minutes | 125°F (medium-rare) |
| 1 1/2 inch | 15–18 minutes | 125°F (medium-rare) |
| 1 3/4 inch | 18–22 minutes | 125°F (medium-rare) |
| 2 inches | 22–28 minutes | 125°F (medium-rare) |
| 2 1/2 inches | 28–35 minutes | 125°F (medium-rare) |
Want medium instead? Pull closer to 135°F and still rest it. If you’re cooking for someone who prefers well-done, choose a fattier cut instead of forcing a lean round steak past 150°F. Past that point, texture tends to tighten up fast.
Bake London Broil In The Oven Step By Step
This is the core method. It’s simple, and it rewards you for doing the little things cleanly.
1) Dry, Salt, And Give It Time
Pat the steak dry with paper towels. Salt it on both sides. If you can, salt 45 minutes ahead, or up to overnight on a rack in the fridge. That short dry-brine seasons deeper and helps the surface brown instead of steaming.
2) Heat The Oven And Pan
Set the oven to 450°F. Slide a sheet pan inside while it heats. A hot pan jump-starts browning the moment the meat hits it. If you’re using a wire rack, place it on the pan now.
3) Season And Oil Right Before Baking
Right before cooking, rub the steak with a thin sheen of oil. Add black pepper and any dry spices. Save sweet glazes for the final minutes since sugar can scorch at 450°F.
4) Bake To Temperature, Not To The Clock
Place the steak on the hot pan or rack. Insert the thermometer probe into the thickest part from the side. Bake until it hits your pull temperature. For medium-rare, pull at 125°F.
5) Rest Like You Mean It
Move the meat to a board and tent loosely with foil. Rest 10 minutes for thinner pieces, 15 minutes for thicker ones. Resting lets juices settle back into the meat so the slices stay moist inside.
6) Slice Thin Across The Grain
Find the grain lines and cut across them. Hold your knife at a slight angle and slice thin—think 1/8 to 1/4 inch. Thick slices make lean cuts feel chewier. Thin slices eat like a different meal.
Picking The Right Cut For London Broil
The label “london broil” can show up on different muscles. For oven baking, aim for a piece that’s thick, evenly shaped, and not full of seams. Top round is common and budget-friendly. Flank has stronger beefy flavor and a looser grain that slices well.
At the store, look for:
- Thickness of at least 1 1/4 inches
- Even shape, with no paper-thin tail
- Minimal surface moisture in the package
Baking London Broil In The Oven Without Drying It Out
Dry london broil usually comes from heat that runs too long. The fix is short, hot cooking plus a clear pull temperature. Use the thermometer early, not at the end, so you can slow down if it climbs fast.
Two extra moves help a lot:
- Use a rack: Air under the meat keeps the bottom from steaming in its own juices.
- Rest longer for thick cuts: Give a 2-inch piece a full 15 minutes before slicing.
Marinade Options That Fit A Lean Cut
Marinade won’t turn a lean steak into a pot roast, yet it can add flavor and help the surface brown. Keep it simple: salt still does most of the work, and too much acid can make the outer layer turn mealy.
Quick Savory Marinade
- 2 tablespoons soy sauce
- 1 tablespoon Worcestershire
- 1 tablespoon oil
- 2 garlic cloves, grated
- 1 teaspoon smoked paprika
Marinate 30 minutes to 4 hours. Pat dry before baking so it browns. If you marinate overnight, skip extra salt until you taste the marinade first.
Herb And Citrus Marinade
- 2 tablespoons oil
- 1 tablespoon lemon juice
- 1 teaspoon dried oregano
- 1/2 teaspoon ground cumin
- 1/2 teaspoon black pepper
Keep citrus time shorter—30 to 90 minutes works well. Longer soaks can over-soften the surface.
Choosing Doneness And Staying On The Safe Side
For most london broil cuts, medium-rare or medium gives the best bite. Since the meat is a solid muscle cut, safety guidance focuses on internal temperature and rest time. The USDA lists 145°F with a 3-minute rest as a safe minimum for steaks and roasts. You can read the exact chart on the USDA safe temperature chart.
If you choose to cook below 145°F, keep food handling tight: clean board, clean knife, and don’t let raw juices hang around. For guests with higher risk, cook to the USDA minimum.
Pan Sear Plus Oven Method For A Deeper Crust
If you want a darker crust and you’ve got a heavy skillet, do a fast sear first. This works best for thicker pieces since the sear adds heat.
- Heat a cast-iron skillet over medium-high until a drop of water skitters.
- Add a teaspoon of oil and sear the steak 60–90 seconds per side.
- Slide the skillet into a 450°F oven and finish to your pull temperature.
Broiler Finish When You Want More Color
If the center hits temperature before the surface looks browned enough, the broiler can help. Move the pan to the top rack, switch to broil, and watch it like a hawk. One to two minutes per side is often plenty.
Keep the door cracked if your oven manual calls for it. Pull the steak the moment the crust looks right, then rest as usual.
Slicing, Serving, And Leftover Plans
London broil shines when you treat it like steak slices, not thick “roast” slabs. Set it on a board, slice, then fan it out on a platter. A pinch of flaky salt on the cut face wakes up flavor.
Easy serving ideas:
- Steak sandwiches with horseradish mayo and arugula
- Tacos with onions, cilantro, and a squeeze of lime
- Rice bowls with cucumbers, sesame, and a soy-ginger drizzle
- Salads with blue cheese, tomatoes, and warm steak strips
Leftovers keep 3–4 days in the fridge. Reheat gently. A quick warm-up in a lidded skillet with a splash of broth keeps slices tender. Microwaves can tighten lean meat fast.
Common Problems And Fast Fixes
If something goes sideways, it’s usually one of a few repeat issues. Use the table to diagnose without guessing.
| Problem | What Caused It | Fix Next Time |
|---|---|---|
| Chewy slices | Overcooked or cut with the grain | Pull at 125–135°F; slice thin across grain |
| Pale surface | Meat went in wet; pan not hot | Pat dry; preheat pan; use a rack |
| Burnt spices | Sugar or fine herbs at high heat | Add sweet glaze late; use coarser spices |
| Dry board puddle | Skipped rest or cut too soon | Rest 10–15 minutes; tent loosely |
| Salty bite | Marinade plus heavy salting | Salt less; taste marinade; pat dry |
| Uneven doneness | Thin tail cooked faster | Fold thin end under; tie with twine |
| Gray edges | Low oven temp or long cook | Use 450°F; try sear-then-oven |
