How Long to Bake London Broil in Oven: The Definitive Guide
Baking London broil in the oven can result in a tender and delicious meal. Generally, you’ll need to bake it for approximately 25-45 minutes, depending on the size of the cut and your desired level of doneness.
Understanding London Broil: A Culinary Journey
London broil isn’t actually a specific cut of meat but rather a preparation method applied to a tough cut, typically flank steak or top round. These cuts benefit immensely from marinating and cooking at a high temperature, followed by slicing against the grain. Baking it in the oven, when done correctly, delivers a perfectly cooked and flavorful result.
Why Bake London Broil? The Advantages
Choosing to bake your London broil offers several advantages:
- Even Cooking: Oven baking provides more uniform heat distribution than grilling or pan-searing, minimizing the risk of burning one area while undercooking another.
- Convenience: Once in the oven, the London broil requires less active attention than other cooking methods.
- Flavor Infusion: Baking allows the marinade’s flavors to fully penetrate the meat, resulting in a more flavorful and tender final product.
- Temperature Control: Easily monitor the internal temperature of the meat for precise doneness.
The Baking Process: A Step-by-Step Guide
How long to bake London broil in oven? depends on factors such as thickness and desired doneness. Here’s a detailed process:
- Marinating: This is crucial! Marinate the London broil for at least 2 hours, or preferably overnight, in the refrigerator. A good marinade will include:
- Acid (vinegar, citrus juice)
- Oil (olive oil, vegetable oil)
- Flavorings (garlic, herbs, spices, soy sauce, Worcestershire sauce)
- Preheating: Preheat your oven to a high temperature, typically 400-450°F (200-230°C).
- Preparing the Meat: Remove the London broil from the marinade and pat it dry with paper towels. This promotes better browning.
- Searing (Optional): For added flavor, sear the London broil in a hot skillet with oil on all sides for 2-3 minutes before transferring it to the oven.
- Baking: Place the London broil on a baking sheet or roasting pan.
- Monitoring Temperature: Use a meat thermometer to track the internal temperature.
- Rare: 125-130°F (52-54°C)
- Medium-Rare: 130-135°F (54-57°C)
- Medium: 135-145°F (57-63°C)
- Medium-Well: 145-155°F (63-68°C)
- Well-Done: 155°F+ (68°C+)
- Resting: Remove the London broil from the oven and let it rest for 10-15 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful result.
- Slicing: Slice the London broil thinly against the grain. This is essential for tenderness.
Time Table for London Broil Baking: Guide
| Doneness | Internal Temperature | Approximate Baking Time (425°F) |
|---|---|---|
| Rare | 125-130°F | 25-30 minutes |
| Medium-Rare | 130-135°F | 30-35 minutes |
| Medium | 135-145°F | 35-40 minutes |
| Medium-Well | 145-155°F | 40-45 minutes |
| Well-Done | 155°F+ | 45+ minutes |
Note: These times are estimates and can vary based on the thickness and starting temperature of the meat.
Common Mistakes and How to Avoid Them
- Skipping the Marinade: This is a crucial step. Marinating tenderizes the meat and infuses it with flavor.
- Overcooking: Use a meat thermometer and err on the side of undercooking, as the meat will continue to cook while resting.
- Not Resting the Meat: Resting allows the juices to redistribute, resulting in a more tender and flavorful London broil.
- Slicing with the Grain: This results in tough, chewy meat. Always slice thinly against the grain.
- Baking at Too Low a Temperature: London Broil benefits from high heat to develop a good crust and cook quickly.
Frequently Asked Questions (FAQs)
What is the ideal internal temperature for a medium-rare London broil?
The ideal internal temperature for a medium-rare London broil is 130-135°F (54-57°C). Using a meat thermometer is the best way to ensure accurate doneness.
Can I bake a frozen London broil?
While not recommended, you can bake a frozen London broil. However, it will take significantly longer to cook, and the texture may be compromised. It’s always best to thaw the meat completely in the refrigerator before baking.
What is the best marinade for London broil?

How do I know when my London broil is done?
The most reliable method is to use a meat thermometer. Insert the thermometer into the thickest part of the meat, avoiding bone or fat. Refer to the temperature chart above for desired doneness.
Can I use a convection oven to bake London broil?
Yes, you can use a convection oven. Reduce the oven temperature by 25°F (15°C) and check the meat more frequently, as convection ovens cook food faster.
What is the best way to slice London broil?
The most important thing is to slice against the grain. Look closely at the meat to identify the direction of the muscle fibers and slice perpendicular to them.
How long should I rest the London broil after baking?
Allow the London broil to rest for 10-15 minutes before slicing. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful final product.
What sides go well with London broil?
