How to Cook London Broil in the Oven at 400 in 3 Simple Steps

To cook London Broil in the oven at 400°F, start by marinating the meat for up to 24 hours. This step is key to boosting both flavor and tenderness, giving you a juicy and delicious result.

Next, heat a skillet until it’s really hot and sear the meat for 2–3 minutes per side. This locks in the juices and creates a nice crust.

Then, transfer the skillet to your preheated oven and roast the meat for 10–15 minutes, depending on how well done you like it.

Finally, don’t skip resting the meat for 10 minutes. This helps the juices redistribute, making every bite tender.

When you’re ready, slice the London Broil thinly against the grain to maximize tenderness. Keep going to uncover tips for perfect results!

Preparing and Marinating the London Broil

Before you start cooking, prepare and marinate your London Broil to boost its flavor and tenderness. Begin your meat preparation by perforating the London broil with a fork to help the marinade ingredients penetrate deeply. This ensures ideal flavor infusion and meat tenderizing.

Combine garlic, soy sauce, balsamic vinegar, Worcestershire sauce, and olive oil for a marinade that enhances taste and texture. Place the meat and marinade in a resealable bag or shallow dish, flipping occasionally during the marinating time.

Make sure to refrigerate the steak below 40°F to keep it safe and tender, but don’t exceed 24 hours. Before cooking at your set oven temperature, take the London broil out of the fridge about 30 to 60 minutes early. This helps bring it to room temperature, which promotes even cooking.

Searing and Roasting at 400°F

Once your London Broil has marinated and reached room temperature, you’re ready to develop a flavorful crust by searing it.

Preheat your oven to 400°F and heat a cast iron skillet over high heat until it’s smoking hot. Place the London Broil in the skillet and sear each side for 2-3 minutes until a deep brown crust forms. This oven searing locks in juices and flavor.

Next, transfer the skillet directly to the preheated oven to roast the meat at this consistent oven temperature. Roast for 10-15 minutes, depending on your preferred doneness.

Use a meat thermometer to check the internal temperature—135°F signals medium-rare. This method of oven roasting after searing ensures a tender, juicy London Broil with a perfect crust.

Resting and Slicing for Tenderness

While the London Broil rests under loosely tented foil for 10 minutes, the juices redistribute throughout the meat. This ensures every bite stays juicy and flavorful.

This resting period is essential because cutting into the steak too soon causes the juices to escape, leading to dryness. During this rest time, keep the meat covered with foil to maintain warmth and moisture.

When it’s time to slice, use a sharp carving knife to make clean, even cuts. Always slice against the grain, cutting thin strips about 1/4 inch thick.

Cutting against the grain breaks down muscle fibers, which maximizes tenderness. By following this resting and slicing method, you’ll enjoy a tender, juicy London Broil every time.

Conclusion

Now that you’ve guided your London Broil through its warm oven journey and let it take a gentle, well-deserved pause, you’re ready to reveal a masterpiece.

Slicing it just right reveals tender, juicy layers that practically melt in your mouth. With these simple steps, you’ve transformed a humble cut into a flavorful celebration.

Enjoy the fruits of your culinary patience—it’s a dinner worth savoring and sharing. Cooking London Broil in the oven at 400 is easy and rewarding, delivering juicy, tender results every time. So go ahead, dig in and impress your guests with this delicious oven-cooked London Broil!
