Ingredient List

Here’s what you’ll need for this delicious London Broil slow cooker recipe:

• 2-3 pounds London Broil (flank steak or top round can work as alternatives)
• 1/2 cup soy sauce (adds depth and umami)
• 1/4 cup balsamic vinegar (for a touch of tanginess)
• 2 tablespoons Worcestershire sauce (classic savory punch)
• 3 cloves garlic, minced (garlic makes everything better)
• 1 medium onion, thinly sliced (adds sweetness and body)
• 1 teaspoon dried rosemary (or 2 sprigs fresh)
• 1 teaspoon dried thyme (or a few fresh sprigs)
• 1/2 teaspoon black pepper
• 1/4 teaspoon salt (adjust to taste)
• 1/4 cup beef broth or water (helps with slow cooker moisture and flavor infusion)
• Optional: 1 tablespoon brown sugar or honey (for subtle caramelization)

Instruction Guide

Cooking London Broil in the slow cooker is easier than you might think. Here’s a step-by-step guide that will guarantee tender, juicy results:

1. Prepare The Marinade

   • In a medium bowl, whisk together soy sauce, balsamic vinegar, Worcestershire sauce, minced garlic, and optional brown sugar or honey. This combination will coat the meat and infuse it with incredible flavor.

2. Sear The Meat (optional But Recommended)

   • Heat a skillet over medium-high heat. Sear the London Broil for 2-3 minutes on each side until browned. This step adds extra flavor but can be skipped if you’re short on time.

3. Layer In The Slow Cooker

   • Place sliced onions at the bottom of the slow cooker. Lay the seared (or raw) London Broil on top. Pour the marinade over the meat and add the beef broth or water. Sprinkle rosemary, thyme, salt, and pepper over everything.

4. Cook Low And Slow

   • Cover and cook on low for 6-8 hours or high for 3-4 hours, depending on your schedule. The low-and-slow method ensures the meat is tender and infused with all those flavors.

5. Rest And Slice

   • Once done, remove the London Broil from the slow cooker and let it rest for 5-10 minutes before slicing. Always slice against the grain to maximize tenderness.

6. Serve And Enjoy

   • Spoon some of the cooking juices over the sliced meat for extra flavor. Pair with mashed potatoes, roasted vegetables, or a simple side salad for a complete meal.

Ingredient Swaps

Cooking is all about flexibility. Here are some ingredient swaps to accommodate what you have in your pantry:

• Soy sauce: Tamari (gluten-free) or coconut aminos for a milder flavor.
• Balsamic vinegar: Red wine vinegar or apple cider vinegar for a different tang.
• Beef broth: Chicken broth or vegetable broth works in a pinch.
• Garlic: Garlic powder or roasted garlic paste if fresh isn’t available.
• Herbs: Swap rosemary or thyme with oregano, sage, or Italian seasoning blends.

Helpful Tips

• Trim excess fat: London Broil can have a thick fat cap; trimming it slightly helps prevent a greasy dish.
• Marinate overnight: If you have time, marinating the meat overnight in the refrigerator will dramatically increase flavor penetration.
• Don’t skip resting: Letting the meat rest before slicing locks in juices and prevents dryness.
• Check liquid levels: Make sure there’s enough liquid to avoid burning but not so much that the meat stews instead of braises.

Customization Ideas

Here’s where you can get creative and make this London Broil your own:

• Add vegetables: Carrots, potatoes, mushrooms, or bell peppers cook beautifully alongside the meat.
• Spicy kick: Add red pepper flakes or a splash of sriracha for some heat.
• Sweet twist: Incorporate pineapple juice, apple cider, or a touch of maple syrup into the marinade.
• Herb-forward: Fresh herbs added at the end, like parsley or basil, can brighten the dish.
• Asian-inspired: Use ginger, hoisin sauce, and sesame oil for a unique fusion flavor.

FAQs

What Cut Of Meat Is Best For A London Broil Slow Cooker Recipe?

London broil typically refers to flank steak or top round steak. Both cuts are lean and benefit from slow cooking, which helps break down the muscle fibers and results in a tender, flavorful dish.

Do I Need To Sear The London Broil Before Placing It In The Slow Cooker?

Searing the meat is optional but recommended. Browning the exterior of the London broil in a hot skillet for 2-3 minutes per side adds depth of flavor and improves the overall appearance of the dish.

What Is The Ideal Cooking Time And Temperature For London Broil In A Slow Cooker?

Cook the London broil on low heat for 6-8 hours or on high for 3-4 hours. Low and slow cooking ensures the meat becomes tender without drying out.

What Liquids Can I Use In A Slow Cooker London Broil Recipe?

Common liquids include beef broth, red wine, soy sauce, or a combination. These liquids help keep the meat moist, enhance flavor, and create a rich sauce or gravy.

Can I Add Vegetables To My London Broil Slow Cooker Recipe?

Yes, root vegetables like carrots, potatoes, and onions work well. Add them at the beginning of cooking so they absorb the meat’s flavors and become tender.

How Do I Prevent The London Broil From Becoming Dry In The Slow Cooker?

Use enough liquid to partially cover the meat, avoid overcooking, and cook on low rather than high heat. Additionally, letting the meat rest for 10-15 minutes after cooking helps retain juices.

Can I Make A Marinade For The London Broil And Cook It Directly In The Slow Cooker?

Yes, marinating the meat for 2-24 hours before slow cooking can enhance flavor and tenderness. Include acidic components like vinegar, citrus juice, or wine in the marinade to help break down muscle fibers.

Do I Need To Flip The London Broil During Slow Cooking?

Flipping is generally not necessary in a slow cooker since the cooking is gentle and even. However, you can turn it halfway through cooking if you want to ensure the meat is evenly coated with sauce or juices.

How Should I Slice London Broil After Slow Cooking?

Always slice London broil against the grain, which shortens muscle fibers and makes the meat more tender. This is especially important for lean cuts like flank or top round.

Can Leftovers Be Stored And Reheated Safely?

Yes, store leftover London broil in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in a covered pan on low heat or in the microwave to avoid drying out the meat.
