How To Cook A London Broil In The Oven

ByLily

Oven-roasting London broil is a hands-off approach that produces even cooking throughout, perfect for busy weeknights. If you want to know how to cook a london broil in the oven, the process is simpler than most people think. You just need a good cut of meat, a hot oven, and a little patience while it rests.

London broil is actually not a specific cut of beef. It usually refers to top round, but flank steak or sirloin tip can work too. The name describes a cooking method more than the meat itself.

In this guide, you will learn the exact steps for oven-roasting. From seasoning to slicing, every detail matters for a tender result.

What You Need Before You Start

Gather your tools and ingredients first. This keeps the process smooth and stress-free.

  • A 2 to 3 pound London broil (top round works best)
  • Kosher salt and black pepper
  • Olive oil or a neutral cooking oil
  • A cast iron skillet or heavy oven-safe pan
  • An instant-read meat thermometer
  • Aluminum foil for resting
  • A sharp carving knife

You also need about 10 minutes of prep time. The oven does the rest of the work.

How To Cook A London Broil In The Oven

Follow these steps in order. Each one builds on the last for a tender, flavorful result.

Step 1: Bring The Meat To Room Temperature

Take the London broil out of the fridge 30 to 45 minutes before cooking. Cold meat cooks unevenly. Letting it sit on the counter helps the center warm up slightly.

Pat the surface dry with paper towels. Moisture steams the meat instead of searing it. Dry meat gives you a better crust.

Step 2: Season Generously

Rub the steak with oil on all sides. Then apply salt and pepper. Use more salt than you think you need. A good rule is about one teaspoon of kosher salt per pound of meat.

You can add garlic powder, onion powder, or dried herbs if you like. Keep it simple so the beef flavor stays front and center.

Step 3: Preheat The Oven And Pan

Set your oven to 450 degrees Fahrenheit. Place a cast iron skillet inside while it preheats. A hot pan creates a quick sear on the outside of the meat.

Let the oven and pan heat for at least 15 minutes. This step is critical for a good crust.

Step 4: Sear The Meat On The Stovetop

Carefully move the hot skillet to your stovetop over medium-high heat. Place the seasoned London broil in the pan. Sear for 2 to 3 minutes per side without moving it.

You want a deep brown color on both sides. This builds flavor and texture.

Step 5: Transfer To The Oven

Move the skillet into the preheated oven. Roast for about 10 to 15 minutes depending on thickness. A one-inch thick steak usually takes 12 minutes for medium-rare.

Use your meat thermometer to check doneness. Pull the meat at 125 degrees for rare, 130 for medium-rare, or 140 for medium. The temperature will rise another 5 to 10 degrees while resting.

Step 6: Rest The Meat

Place the London broil on a cutting board or plate. Tent it loosely with foil. Let it rest for 10 minutes.

Resting allows the juices to redistribute. If you cut too early, those juices run out and leave the meat dry.

Step 7: Slice Against The Grain

Look at the surface of the meat. You will see lines running through it. These are the muscle fibers.

Cut perpendicular to those lines. This shortens the fibers and makes each bite tender. Slice thinly, about a quarter inch thick.

Tips For A Tender London Broil Every Time

London broil can be tough if you rush it. These tips help you avoid common mistakes.

  • Do not skip the rest time. It is not optional.
  • Always slice against the grain. This is the single most important step for tenderness.
  • Do not overcook. Medium-rare is the sweet spot for this cut.
  • Use a thermometer. Guessing leads to dry meat.
  • Let the pan get very hot before searing.
  • Cut thin slices. Thick pieces feel tougher.

Common Mistakes To Avoid

Many people ruin London broil without realizing why. Here are the usual culprits.

Cooking It Cold

Straight from the fridge to the pan causes uneven cooking. The outside burns while the inside stays raw.

Skipping The Sear

Searing adds flavor and texture. Without it, the meat looks gray and tastes bland.

Cutting With The Grain

This makes even a perfectly cooked steak chewy. Always check the direction of the fibers before slicing.

Not Resting The Meat

Juices need time to settle. Cutting immediately wastes all that moisture on the cutting board.

Serving Suggestions

London broil pairs well with many sides. Keep it simple and let the beef shine.

  • Roasted potatoes with rosemary
  • Steamed green beans with lemon
  • A simple garden salad with vinaigrette
  • Grilled asparagus
  • Crusty bread for sopping up juices

Leftovers taste great in sandwiches or on top of a salad. Store them in the fridge for up to three days.

Final Thoughts

Oven-roasting is the easiest way to cook London broil. You get consistent results with minimal effort. Just season, sear, roast, rest, and slice against the grain.

Once you master this method, you can adjust the seasoning and sides to fit your taste. The technique stays the same. With a little practice, you will cook a tender London broil every single time.
