The Benefits of Oven-Cooking London Broil
Oven-cooking offers several advantages:
- Consistent Temperature Control: Allows for even cooking and reduces the risk of burning.
- Hands-Off Approach: Frees you up to prepare side dishes while the meat roasts.
- Minimal Mess: Less splattering and easier cleanup compared to pan-frying.
- Precise Doneness: Using a meat thermometer ensures perfect results every time.
Essential Steps for Oven-Cooked London Broil
The key to a delicious, tender London Broil lies in these steps:
- Marinating: A good marinade is crucial for tenderizing and adding flavor.
- Use acidic ingredients like vinegar or citrus juice to break down muscle fibers.
- Include flavorful elements like garlic, herbs, soy sauce, and Worcestershire sauce.
- Marinate for at least 2 hours, but ideally overnight.
- Searing (Optional but Recommended): Searing creates a flavorful crust.
- Preheat a cast-iron skillet or oven-safe pan over high heat.
- Sear the London Broil for 2-3 minutes per side.
- Roasting: Finish cooking in the oven.
- Preheat your oven to 375°F (190°C).
- Place the seared (or unseared) London Broil in a roasting pan.
- Roast until the internal temperature reaches your desired doneness (see table below).
- Resting: Let the meat rest before slicing.
- Tent the London Broil loosely with foil and let it rest for 10-15 minutes. This allows the juices to redistribute, resulting in a more tender and flavorful final product.
- Slicing: Slice against the grain.
- Locate the direction of the muscle fibers.
- Slice perpendicular to the fibers to shorten them and make the meat easier to chew.
Doneness Temperatures for London Broil

| Doneness | Internal Temperature (°F) | Internal Temperature (°C) |
|---|---|---|
| Rare | 125-130 | 52-54 |
| Medium-Rare | 130-135 | 54-57 |
| Medium | 135-145 | 57-63 |

Frequently Asked Questions (FAQs)
What exactly is London Broil?
London Broil is not a specific cut of meat, but rather a method of preparing a tough cut of beef, typically flank steak or top round. It involves marinating, searing, and either broiling or roasting the meat to achieve a more tender result.
Can I cook a London Broil from frozen?
While it’s not recommended, you can cook a London Broil from frozen. However, the results will be less tender and the cooking time will be significantly longer. Ideally, thaw the meat completely in the refrigerator before cooking.
How long should I marinate the London Broil?
At a minimum, marinate for at least 2 hours. For best results, marinate overnight or even for 24 hours in the refrigerator. The longer the meat marinates, the more tender and flavorful it will become.
Do I need to sear the London Broil before roasting it?
Searing is optional, but highly recommended. Searing creates a flavorful crust that enhances the overall taste and texture of the London Broil. If you choose to skip searing, the meat will still be cooked, but it may lack that desirable browned exterior.
What temperature should I cook a London Broil in the oven?
A temperature of 375°F (190°C) is ideal for roasting London Broil. This temperature allows the meat to cook evenly without drying out.
How long does it take to cook a London Broil in the oven?
Cooking time depends on the thickness of the steak and your desired level of doneness. Generally, it takes 15-25 minutes to cook a London Broil to medium-rare at 375°F (190°C). Use a meat thermometer to ensure accurate results.
How do I know when the London Broil is done?
The best way to determine doneness is to use a meat thermometer. Insert the thermometer into the thickest part of the steak, avoiding bone or fat. Refer to the temperature chart above for desired internal temperatures.
Why is my London Broil so tough?
The most common reason for a tough London Broil is overcooking. London Broil is a lean cut of meat and becomes tough when cooked beyond medium-rare. Also, failing to marinate adequately or slice against the grain can contribute to toughness.
What is the best way to slice a London Broil?
Always slice against the grain. This means cutting perpendicular to the direction of the muscle fibers. This shortens the fibers and makes the meat significantly easier to chew.
Can I use a broiler instead of roasting?
Yes, you can broil London Broil. Preheat your broiler to high and place the steak on a broiler pan. Broil for 4-5 minutes per side for medium-rare, watching carefully to prevent burning.
What are some good side dishes to serve with London Broil?
Popular side dishes include mashed potatoes, roasted vegetables (such as asparagus, Brussels sprouts, or carrots), salad, and rice. Consider the flavors in your marinade when choosing side dishes to create a complementary meal.
Can I reheat leftover London Broil?
Yes, you can reheat London Broil, but it’s best to do so gently to avoid drying it out. Wrap the steak tightly in foil and reheat it in a low oven (250°F/120°C) or slice thinly and pan-fry briefly. Microwaving is not recommended as it can make the meat tough.
