A perfectly broiled london broil is one of the great underrated weeknight wins — a blistering, charred crust on the outside, a rosy, juicy center within, and the whole thing on the table in under 30 minutes. I’ve been refining this method in my kitchen for years, and I’ve found that broiling is actually the closest thing to grilling you can do indoors: intense, direct radiant heat from above that triggers the Maillard reaction just as aggressively as live coals below.
The key is treating your oven broiler like the high-heat tool it is — not a finishing step, but the star of the show.
Why You’ll Love This Recipe
The broiler is criminally underused. At full power, a conventional oven broiler delivers 500–550°F (260–288°C) of radiant heat from just a few inches away — that’s hot enough to form a genuinely caramelized, slightly charred crust on your london broil in about 5–6 minutes per side.
Compared to pan-searing, broiling exposes the entire surface of the meat simultaneously, producing a more even crust with less intervention. And unlike a slow cooker, the broiler is a speed play — from marinade to plate in 30 minutes flat when you need dinner on a Wednesday night.
The Butcher’s Selection
- 2 lb top round london broil (1–1.5 inches thick)
- 3 tbsp olive oil
- 3 tbsp soy sauce
- 2 tbsp Worcestershire sauce
- 1 tbsp red wine vinegar
- 4 garlic cloves, minced
- 1 tsp Dijon mustard
- 1 tsp smoked paprika
- ½ tsp black pepper (coarsely ground)
- ½ tsp kosher salt
- Optional: 1 tsp fresh rosemary, minced
How to Make Broiled London Broil
- Score and marinate. Use a sharp knife to score the london broil in a crosshatch pattern, ¼ inch deep, across both sides. This lets the marinade penetrate the dense muscle fibers. Combine all marinade ingredients and coat the beef completely. Marinate refrigerated for at least 2 hours, up to 8.
- Prepare the broiler. Position your oven rack 4–5 inches from the broiler element. Preheat on HIGH for 10 full minutes — the broiler pan and rack must be screaming hot before the meat goes in. A cold pan = no crust formation.
- Pat dry before broiling. Remove beef from marinade and pat the surface thoroughly dry with paper towels. Surface moisture turns to steam and prevents the Maillard reaction. Dry = crust.
- Broil the first side. Place beef on the hot broiler pan. Broil 5–6 minutes without opening the oven. You’re looking for a deep mahogany, lightly charred surface — not grey. Watch through the oven window.
- Flip and finish. Flip once and broil 4–5 more minutes for medium-rare. Check with an instant-read thermometer: target Medium-Rare 130–135°F / 54–57°C — remember you’re pulling it 5°F early, as carryover cooking continues during rest.
- Rest on a rack, not a plate. Transfer to a wire rack set over a rimmed baking sheet and rest 8–10 minutes. A plate traps steam and softens the crust you worked hard to build. The rack keeps air circulating on all sides.
- Slice thin, against the grain. Identify the direction of the muscle fibers — cut your knife perpendicular to them at a slight diagonal angle. Aim for slices no thicker than ¼ inch. This technique shortens the muscle fibers in every bite and is the single biggest factor in perceived tenderness.
Pro Cooking Tips
For more marinade ideas that work equally well under the broiler or on the grill, our london broil marinade guide covers classic, Asian, and herb-based options with full ratios.
Use a cast iron or broiler pan — never a glass baking dish. Glass can shatter under direct broiler heat. Cast iron retains heat and gives you better browning on the bottom of the steak through conduction.
Watch it constantly after the 4-minute mark. A 30-second difference between perfect char and burnt crust is real at broiler temperatures. Stay at the oven.
Recipe Variations
🧄 Garlic-Herb Crust
In the last 2 minutes of broiling, brush the surface with a garlic-herb butter (softened butter + roasted garlic + thyme). The dairy solids brown under the broiler adding rich, nutty depth.
🌿 Keto / Low-Carb
The base recipe is already keto-friendly. Serve sliced over arugula with olive oil and parmesan instead of carb-heavy sides. The peppery arugula cuts through the rich beef perfectly.
🍋 Chimichurri Finish
Top each slice with fresh chimichurri (parsley, garlic, red wine vinegar, oil, red pepper flakes). The brightness of the vinegar and herbs cuts through the charred beefiness beautifully.
🫙 Make-Ahead Option
Marinate the london broil up to 24 hours ahead — the acid and salt will tenderize and season the meat deeply. Pull from fridge 30 minutes before broiling for even cooking.
What to Serve With This Dish
- Roasted garlic mashed potatoes
- Sautéed mushrooms in butter
- Grilled asparagus with lemon
- Classic Caesar salad
- Baked sweet potato
- Chimichurri rice
Storage & Meal Prep
Store sliced beef in an airtight container up to 3 days. Add a splash of broth to keep it moist.
Wrap individual portions tightly in foil then freeze. Best within 2 months for maximum juiciness.
Thin slices make excellent steak sandwiches, salad toppers, or filling for lettuce wraps next day.

Common Mistakes to Avoid
FAQs
How long do I broil london broil per side?
For a 1–1.5 inch thick cut: 5–6 minutes on the first side, 4–5 minutes on the second. Always confirm with an instant-read thermometer rather than time alone — every oven broiler varies significantly.
Do I need to marinate london broil before broiling?
Strongly recommended. The acid in the marinade (vinegar or citrus) breaks down tough surface proteins and helps the meat absorb seasoning. A 2-hour minimum makes a noticeable difference in both flavor and tenderness.
What’s the safe internal temperature for broiled london broil?
USDA minimum for beef is 145°F (63°C). For london broil, I recommend pulling at 130–135°F (54–57°C) for medium-rare, which gives you the most tender, juicy result with this lean cut.
Can I broil london broil in a regular oven (not convection)?
Yes — standard broiler works perfectly. Convection broiling circulates hot air for slightly more even browning, but a conventional broiler at full power delivers excellent results when the rack is positioned correctly.

Scrumptious
My husband (who is extremely picky) loved the liver & onions so much!! I didn’t have any beef broth or Sherry so I used about a tbl of Worcestershire and 1/4 c of white wine …..it was scrumptious
Response from MeatRecipesBox
Oh wow, I’m so happy to hear that!! 😍 I love that you made it work with what you had on hand — Worcestershire and white wine sound like a delicious twist. So glad your husband enjoyed it, especially being picky! Thank you for sharing your version, it makes me smile knowing it turned out scrumptious!
This was amazing
This recipe turned out really amazing! It’s juicy and spiced deliciously. I definitely would use less of the spicy pepper next time, but it really was delicious and I don’t think I’ll make chicken legs any other way from now on.!
Response from MeatRecipesBox
Thank you for taking the time to leave such a thoughtful review. I’m really glad to hear the recipe turned out juicy and full of flavor for you. That’s exactly what I was hoping for when putting it together. Good call on the spicy pepper as well. Adjusting the heat level to your own taste is always the best approach, and using a little less next time should make it just right for you. I really appreciate you trying the recipe and sharing your experience. It’s great to know it worked so well for you.
