Getting a tender and flavorful London broil from your oven is easier than you think. This guide will show you exactly How To Bake London Broil In The Oven for a perfect result everytime.
London broil isn’t a specific cut of meat. It’s actually a cooking method. The name usually refers to lean, tougher cuts like top round or flank steak. The secret isn’t a fancy ingredient. It’s in how you prepare and cook it. With the right technique, you can turn an economical cut into a stunning centerpiece meal.
How To Bake London Broil In The Oven
This is your master blueprint. We’ll break down each step in detail below, but here’s the core process you’ll follow.
- Select and prepare your steak.
- Create a simple, effective marinade.
- Marinate for the optimal time.
- Pat dry and bring to room temp.
- Sear it in a hot pan (crucial step!).
- Bake to your perfect doneness.
- Rest before slicing thinly against the grain.
Choosing the Right Cut of Meat
Your first step is picking the steak. This choice impacts everything. Look for a cut that’s about 1.5 to 2 inches thick. This gives you room for a good sear and a juicy interior.
The most common cuts labeled “London Broil” are:
- Top Round Steak: Lean and affordable. It benefits greatly from marinating.
- Flank Steak: More flavorful and fibrous. It’s also a great candidate.
- Shoulder Steak: Sometimes used. It can be a bit tougher but very tasty.
At the store, look for meat with a bright red color and some marbling. The fat will melt during cooking, adding flavor and moisture. Don’t worry if it seems lean. Our method will handle that.
The Essential Marinade for Flavor and Tenderness
A good marinade has three jobs: add flavor, tenderize, and keep the meat moist. You don’t need a long list of ingredients. Acid, oil, salt, and aromatics are key.
Here is a reliable, all-purpose marinade recipe:
- 1/2 cup soy sauce or tamari
- 1/4 cup olive oil
- 2 tablespoons fresh lemon juice or vinegar
- 4 cloves garlic, minced
- 1 tablespoon Worcestershire sauce
- 1 teaspoon black pepper
- 1 teaspoon dried herbs (like thyme or rosemary)
Whisk it all together in a bowl. The acid (lemon juice) helps break down tough muscle fibers. The oil carries flavor and adds moisture. Salt (from the soy sauce) is essential for seasoning deep into the meat.
Place your steak in a large resealable bag or shallow dish. Pour the marinade over it, turning to coat. Get as much air out of the bag as possible before sealing it. This ensures the liquid is in full contact with the meat.
How Long Should You Marinate?
Timing is important. Too short, and the flavor won’t penetrate. Too long, and the acid can make the meat mushy.
- Minimum: 2 hours at room temperature.
- Ideal: 6 to 12 hours in the refrigerator.
- Maximum: 24 hours for very thick, tough cuts.
If you’re short on time, even 30 minutes will help. But for the best texture, aim for that 6-hour window. Always marinate in the fridge if it will be more than 2 hours.
Preparing to Cook: Key Steps Before Baking
Don’t just throw the marinated steak in the oven. Two simple steps make a huge difference.
First, take the steak out of the fridge about 30-45 minutes before cooking. Let it come closer to room temperature. A cold steak won’t cook evenly. The outside will overcook before the center is done.
Second, pat the steak completely dry with paper towels. This is non-negotiable. Moisture is the enemy of a good sear. You want the surface as dry as possible so it browns beautifully instead of steaming.
Lightly season the dried steak with a little extra salt and pepper if you like. The marinade is salty, so you may not need much.
The Two-Part Cooking Method: Sear Then Bake
This is the magic. We use the stovetop and the oven together. The sear creates a flavorful crust. The oven gently cooks the inside to perfection.
Step 1: Preheat Your Oven and Pan.
Preheat your oven to 400°F (200°C). Then, place a heavy oven-safe skillet (cast iron is perfect) on the stovetop over medium-high heat. Let it get very hot. You should see wisps of smoke.
Step 2: Sear the Steak.
Add a high-smoke-point oil (like canola or avocado) to the hot pan. Carefully place the dried London broil in the center. Do not move it for 3-4 minutes. Let a deep brown crust form. Then, flip it and sear the other side for another 3-4 minutes. Sear the edges too, if you can.
Step 3: Transfer to the Oven.
With the steak seared in the oven-safe skillet, move the entire pan to the preheated oven. If your skillet isn’t oven-safe, transfer the steak to a baking sheet or roasting pan.
Baking Time and Temperature Guide
Baking time depends on thickness and your desired doneness. Use a meat thermometer for accuracy. It’s the only way to be sure.
For a 1.5-inch thick London broil at 400°F:
- Rare (125°F): 5-8 minutes in the oven
- Medium-Rare (135°F): 8-12 minutes
- Medium (145°F): 12-15 minutes
- Medium-Well (150°F): 15-18 minutes
Remember, the temperature will rise about 5-10 degrees while resting. So, remove the steak from the oven when it’s 5-10 degrees below your target final temperature. Check it early to avoid overcooking.
The Most Important Step: Resting and Slicing
Resist the urge to cut into the steak right away. Resting allows the juices, which have been driven to the center by the heat, to redistribute throughout the meat.
Transfer the steak to a cutting board. Loosely tent it with a piece of aluminum foil. Let it rest for a full 10 minutes. This step ensures a juicy steak, not a dry one.
Now, find the direction of the muscle fibers (the “grain”). You’ll see long lines running across the meat. Using a very sharp knife, slice the steak across the grain into thin strips, about 1/4-inch thick. Cutting across the shortens the tough muscle fibers, making each piece much more tender to eat.
Simple Serving Suggestions
Your London broil is the star. Serve it with sides that complement its rich flavor.
- Classic mashed potatoes or roasted baby potatoes.
- A bright, crisp green salad with vinaigrette.
- Simple steamed vegetables like green beans or asparagus.
- For leftovers, slice it thin for amazing sandwiches or salads.
The au jus from the resting meat makes a fantastic simple sauce. Just drizzle it over the sliced steak.
Troubleshooting Common Issues
Even with care, sometimes things don’t go as planned. Here’s how to fix common problems.
My steak is tough. The likely culprits are not marinating long enough, not slicing thinly enough, or (most commonly) not slicing against the grain. Also, overcooking can make it tough.
It didn’t get a good sear. Your pan wasn’t hot enough, or you didn’t dry the steak thoroughly. Make sure you pat it completely dry next time and wait for the pan to be properly hot.
The inside is overcooked. You baked it too long. Use a meat thermometer next time and remember carryover cooking. Also, ensure the steak wasn’t ice-cold when it went in the oven.
It tastes bland. The marinade didn’t have enough salt or time. Be generous with seasoning in the marinade and allow adequate marinating time.
