Perfectly Tender London Broil: An Oven-Baked Guide to Culinary Success
London broil, despite its name, isn’t a specific cut of beef but rather a cooking method applied to a relatively lean and inexpensive cut, typically top round steak. While often grilled, baking London broil in the oven offers a fantastic way to achieve a tender and flavorful result, especially when the weather isn’t cooperating or you prefer a more controlled cooking environment. This comprehensive guide will walk you through every step, from selecting the perfect cut to achieving that melt-in-your-mouth tenderness.
## Understanding London Broil: Choosing the Right Cut
The term “London broil” can be a bit misleading. It usually refers to a thick top round steak, but sometimes flank steak is also sold as London broil. While both can be delicious, top round is generally preferred for oven baking due to its thickness, which helps retain moisture. Here’s what to look for:
* **Top Round Steak:** This is the most common and recommended cut for oven-baked London broil. Look for a piece that’s at least 1 to 1.5 inches thick. A thicker cut will cook more evenly and be less prone to drying out.
* **Flank Steak (Alternative):** If you can’t find top round, flank steak can be used, but it’s crucial to marinate it for a longer period (at least 4 hours, ideally overnight) to tenderize it. Flank steak also cooks much faster, so adjust your cooking time accordingly.
* **Marbling:** Look for a cut with some marbling (flecks of fat within the muscle). This fat will render during cooking, adding flavor and moisture.
* **Color:** The beef should be a vibrant red color, indicating freshness. Avoid cuts that are dull or brownish.
* **Packaging:** Ensure the packaging is airtight and there’s no excessive liquid in the package.
## Essential Equipment
Before you begin, gather the necessary equipment:
* **Oven:** Obviously!
* **Baking Sheet or Oven-Safe Skillet:** A rimmed baking sheet is ideal to catch any juices that may be released during cooking. An oven-safe skillet (cast iron is excellent) will also work well.
* **Meat Thermometer:** This is crucial for ensuring your London broil is cooked to the desired doneness. An instant-read thermometer is the most convenient.
* **Tongs:** For flipping and handling the meat.
* **Cutting Board:** For slicing the cooked London broil.
* **Sharp Knife:** A good knife is essential for slicing the meat against the grain.
* **Mixing Bowl (for Marinade):** To prepare your delicious marinade.
* **Whisk (for Marinade):** To properly mix your marinade ingredients.
* **Plastic Wrap or Resealable Bag:** To marinate the meat.
## The Perfect London Broil Marinade: Flavor and Tenderness
The marinade is the key to a tender and flavorful London broil. A good marinade will tenderize the meat, add moisture, and infuse it with delicious flavors. Here’s a fantastic marinade recipe:
**Ingredients:**
* 1/4 cup olive oil: Adds moisture and helps the marinade penetrate the meat.
* 1/4 cup soy sauce: Provides umami and saltiness.
* 1/4 cup Worcestershire sauce: Adds depth of flavor and tanginess.
* 2 tablespoons balsamic vinegar (or red wine vinegar): Adds acidity, which helps tenderize the meat.
* 2 cloves garlic, minced: For pungent flavor.
* 1 tablespoon Dijon mustard: Adds a subtle tang and helps emulsify the marinade.
* 1 tablespoon honey (or brown sugar): Adds a touch of sweetness and helps with browning.
* 1 teaspoon dried rosemary (or thyme): For herbaceous flavor.
* 1/2 teaspoon black pepper: For a touch of spice.
* 1/4 teaspoon red pepper flakes (optional): For a little heat.
**Instructions:**
1. In a mixing bowl, whisk together all the marinade ingredients until well combined.
2. Place the London broil in a large resealable bag or a shallow dish.
3. Pour the marinade over the meat, ensuring it’s fully coated.
4. Seal the bag or cover the dish with plastic wrap.
5. Marinate in the refrigerator for at least 2 hours, or preferably overnight. The longer the marinating time, the more tender and flavorful the meat will be. If using flank steak, a longer marinating time is essential.
## Preparing the London Broil for Baking
1. **Preheat the Oven:** Preheat your oven to 425°F (220°C). This high heat will help sear the outside of the meat and lock in the juices.
2. **Remove from Refrigerator:** Take the London broil out of the refrigerator about 30 minutes before cooking. This allows the meat to come closer to room temperature, which will result in more even cooking.
3. **Pat Dry:** Remove the London broil from the marinade and pat it dry with paper towels. This helps to achieve a better sear. Discard the marinade after use.
4. **Season (Optional):** While the marinade provides plenty of flavor, you can add a little extra seasoning if desired. A sprinkle of salt and pepper is all you need.
5. **Prepare Baking Sheet:** Line a baking sheet with aluminum foil for easier cleanup. You can also use an oven-safe skillet.
## Baking the London Broil: Step-by-Step Instructions
1. **Sear (Optional but Recommended):** For the best flavor and texture, searing the London broil before baking is highly recommended. You can do this in a hot skillet on the stovetop. Heat a tablespoon of oil in the skillet over medium-high heat. Sear the London broil for 2-3 minutes per side, until browned.
2. **Place in Oven:** Transfer the London broil to the prepared baking sheet or skillet.
3. **Bake:** Bake in the preheated oven for 15-25 minutes, or until the desired internal temperature is reached. The cooking time will depend on the thickness of the steak and your desired level of doneness. Use a meat thermometer to check the internal temperature.
## Determining Doneness: Temperature Guide
Using a meat thermometer is the most accurate way to ensure your London broil is cooked to your liking. Insert the thermometer into the thickest part of the meat, avoiding any bone or fat.
* **Rare:** 125-130°F (52-54°C) – Very red center.
* **Medium-Rare:** 130-135°F (54-57°C) – Warm red center.
* **Medium:** 135-145°F (57-63°C) – Pink center.
* **Medium-Well:** 145-155°F (63-68°C) – Slightly pink center.
* **Well-Done:** 155°F (68°C) and above – No pink.
**Important Note:** The USDA recommends cooking beef to a minimum internal temperature of 145°F (63°C) for safety. However, London broil can become tough if cooked to well-done. Medium-rare to medium is generally recommended for optimal tenderness.
## Resting the Meat: Crucial for Tenderness
Once the London broil reaches the desired internal temperature, remove it from the oven and transfer it to a cutting board. Tent it loosely with aluminum foil and let it rest for at least 10 minutes, or even longer (up to 20 minutes). This resting period is crucial because it allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful result. If you slice the meat immediately after cooking, the juices will run out, leaving you with a dry and less flavorful steak.
## Slicing the London Broil: Against the Grain
The way you slice London broil is just as important as how you cook it. Slicing against the grain is essential for maximizing tenderness. The “grain” refers to the direction of the muscle fibers in the meat. If you slice with the grain, you’ll be cutting along the length of the fibers, resulting in a chewy steak. Slicing against the grain shortens these fibers, making the meat much easier to chew.
1. **Identify the Grain:** Before slicing, carefully examine the London broil to determine the direction of the muscle fibers. They usually run lengthwise across the steak.
2. **Slice Perpendicular to the Grain:** Use a sharp knife to slice the steak perpendicular to the grain, cutting across the fibers at a 45-degree angle. This will ensure the shortest possible fiber length and the most tender result.
3. **Thin Slices:** Aim for thin slices, about 1/4 to 1/2 inch thick. Thinner slices are easier to chew.
## Serving Suggestions: Complementing Your London Broil
London broil is a versatile dish that pairs well with a variety of sides. Here are a few suggestions:
* **Roasted Vegetables:** Roasted asparagus, Brussels sprouts, carrots, or potatoes are all excellent choices.
* **Mashed Potatoes:** Creamy mashed potatoes or garlic mashed potatoes are a classic pairing.
* **Salad:** A fresh green salad or a Caesar salad provides a light and refreshing contrast to the richness of the beef.
* **Grilled Corn on the Cob:** A summertime favorite that complements the flavors of the London broil.
* **Rice Pilaf:** A simple rice pilaf is a great way to soak up the delicious juices from the steak.
* **Horseradish Sauce:** A dollop of horseradish sauce adds a zesty kick.
* **Chimichurri Sauce:** A vibrant Argentinian sauce made with parsley, garlic, vinegar, and olive oil.
