Setting your oven to 400 degrees is a popular method for london broil, producing a nicely browned exterior with a juicy center. If you want to learn how to cook london broil in oven at 400, this guide walks you through every step. You will get a tender, flavorful steak without much fuss.
London broil is not really a cut of meat. It is a cooking method. Most of the time, the meat labeled london broil is top round, flank steak, or sirloin tip. These cuts are lean and can get tough if you cook them wrong.
Using a hot oven at 400 degrees helps you get a good sear on the outside while keeping the inside moist. The key is to not overcook it. Let me show you how.
What You Need Before You Start
Gather your tools and ingredients first. This makes the process smooth. You dont want to run around the kitchen mid-cook.
- 1 to 2 pound london broil steak (about 1 inch thick)
- Olive oil or another high-heat oil
- Salt and black pepper
- Garlic powder, onion powder, or your favorite steak rub
- A cast iron skillet or oven-safe pan
- Meat thermometer
- Aluminum foil
- Cutting board
If your steak is thicker than 1.5 inches, you may need to adjust the cooking time. A meat thermometer is your best friend here. Do not skip it.
How To Cook London Broil In Oven At 400
This is the main event. Follow these steps closely. The result should be a steak with a brown crust and a pink, juicy middle.
Step 1: Prepare The Meat
Take the steak out of the fridge 30 minutes before cooking. Letting it come to room temperature helps it cook evenly. Pat it dry with paper towels. Moisture is the enemy of a good sear.
Rub the steak with a little oil. Then season both sides generously with salt, pepper, and any other spices you like. You can also score the meat lightly with a knife in a diamond pattern. This helps it absorb the seasoning and stay tender.
Step 2: Preheat The Oven And Pan
Set your oven to 400 degrees Fahrenheit. Place a cast iron skillet or oven-safe pan inside while it preheats. A hot pan is crucial for getting a nice crust on the meat.
Let the oven and pan heat for at least 15 minutes. You want that pan screaming hot. When you put the steak in, it should sizzle right away.
Step 3: Sear The Steak
Carefully place the seasoned steak into the hot pan. It may smoke a bit, so turn on your exhaust fan or open a window. Sear for 2 to 3 minutes on one side without moving it. Then flip and sear for another 2 to 3 minutes.
This quick sear locks in juices and creates flavor. Do not skip this step. It makes a big difference in the final texture.
Step 4: Transfer To The Oven
Once both sides are seared, move the entire pan into the preheated oven. Cook for about 6 to 8 minutes for medium-rare. For medium, cook 8 to 10 minutes. The exact time depends on the thickness of your steak and your oven.
Start checking with a meat thermometer at the 6-minute mark. Insert it into the thickest part of the meat, avoiding bone or fat.
- Rare: 120 to 125 degrees F
- Medium-rare: 130 to 135 degrees F
- Medium: 140 to 145 degrees F
- Medium-well: 150 to 155 degrees F
Remember that the temperature will rise another 5 to 10 degrees while resting. So pull it out a little before your target temp.
Step 5: Rest The Meat
This step is often ignored, but it is very important. Take the pan out of the oven and move the steak to a cutting board. Cover it loosely with aluminum foil. Let it rest for 10 minutes.
Resting allows the juices to redistribute inside the meat. If you cut it right away, the juices will run out and you will get a dry steak. Patience pays off here.
Step 6: Slice Against The Grain
Look at the meat and find the direction of the muscle fibers. You want to cut perpendicular to those lines. This shortens the fibers and makes each bite more tender.
Slice the steak into thin strips, about 1/4 inch thick. Serve it right away. Leftovers can be stored in the fridge for up to 3 days.
Tips For A Perfect London Broil Every Time
Here are some extra pointers to help you get consistent results. These small tweaks can make a big difference.
- Use a marinade if you have time. A mix of soy sauce, lemon juice, garlic, and oil works well. Marinate for at least 4 hours or overnight.
- Do not overcrowd the pan. If your steak is too big, cut it in half and cook in batches.
- Let the pan get really hot before adding the meat. A lukewarm pan will steam the steak instead of searing it.
- Check your oven temperature with an oven thermometer. Many ovens run hot or cold.
- For a thicker steak, lower the oven to 375 degrees and cook a bit longer. This prevents the outside from burning before the inside cooks.
- Always slice against the grain. This is the single most important tip for tenderness.
Common Mistakes To Avoid
People often run into the same problems with this cut of meat. Avoid these mistakes and you will be happy with your meal.
- Overcooking the steak. London broil is lean and gets tough fast. Use a thermometer.
- Skipping the rest time. Cutting too early loses all the juice.
- Not drying the meat before searing. Wet meat will not brown properly.
- Using a dull knife. A sharp knife makes clean slices without tearing the meat.
- Cutting with the grain. This makes the steak chewy and hard to eat.
Serving Ideas For Your London Broil
This steak goes with almost anything. Here are some simple sides that pair well.
- Mashed potatoes or roasted potatoes
- Grilled or roasted vegetables
- A fresh green salad
- Rice pilaf or quinoa
- Crusty bread to soak up the juices
You can also use leftover slices in sandwiches, tacos, or stir-fries. It is a versatile piece of meat.
