Ingredients

• 2 pounds London broil
• ¼ cup low-sodium soy sauce
• 1 Tbsp. balsamic vinegar
• 1 Tbsp. Worcestershire sauce
• 1 ¾ cup beef broth (¾ cup separated)
• 1 Tbsp. brown sugar
• ½ tsp. dried rosemary
• ½ tsp. dried thyme
• ¼ tsp. black pepper
• 1 Tbsp. olive oil
• 1 medium onion, sliced
• 2 carrots, peeled and cut into chunks
• 2 potatoes, cut into chunks
• 4 garlic cloves
• 1 Tbsp. cornstarch (optional, for thickening)

Instructions

1. Step 1: In a medium bowl, whisk together soy sauce, balsamic vinegar, Worcestershire sauce, ¾ cup beef broth, brown sugar, dried rosemary, dried thyme, black pepper, and olive oil to create the marinade.
2. Step 2: Place the London broil in a resealable plastic bag or shallow dish and pour the marinade over the meat. Ensure it is evenly coated, then seal or cover and refrigerate for at least 4 hours or overnight.
3. Step 3: Heat a skillet over medium-high heat and sear the London broil on all sides for 2-3 minutes per side. Transfer the seared meat to the slow cooker.
4. Step 4: Arrange sliced onion, carrot chunks, potato chunks, and garlic cloves around the meat in the slow cooker.
5. Step 5: Pour the remaining 1 cup beef broth over the meat and vegetables, ensuring it reaches about halfway up the sides.
6. Step 6: Cover and cook on low for 6-8 hours, or until the meat is fork-tender.
7. Step 7: Remove the London broil from the slow cooker and let it rest 10-15 minutes before slicing against the grain.
8. Step 8: (Optional) Strain the cooking liquid into a saucepan. Mix cornstarch with a few tablespoons of cold water to create a slurry, add to the liquid, and boil while stirring until sauce thickens.
9. Step 9: Serve the sliced London broil with vegetables and drizzle with the savory sauce. Enjoy!

Tips & Variations

• Marinate the meat overnight for deeper flavor and more tender results.
• Use different root vegetables like parsnips or sweet potatoes for variation.
• For a gluten-free option, ensure soy sauce is tamari or gluten-free.
• Skipping the sear step is possible but searing adds extra flavor and locks in juices.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a microwave or on the stovetop over low heat to prevent drying out. The sauce may thicken as it cools; add a splash of broth or water when reheating if needed.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

Can I use a different cut of beef instead of London broil?

Yes, other tougher cuts like flank steak or chuck roast work well in this slow cooker recipe, as the low and slow cooking tenderizes the meat.

Is it necessary to sear the meat before slow cooking?

Searing is not essential, but it enhances flavor by caramelizing the surface and helps lock in juices for a richer taste and better texture.

Instructions

1. Prepare the Marinade: In a medium bowl, whisk together the soy sauce, balsamic vinegar, Worcestershire sauce, ¾ cup of beef broth, brown sugar, dried rosemary, dried thyme, black pepper, and olive oil until well combined.
2. Marinate the Meat: Place the London broil in a resealable plastic bag or shallow dish and pour the marinade over it. Ensure the meat is evenly coated, seal the bag or cover the dish, and refrigerate for at least 4 hours, preferably overnight, to allow the flavors to penetrate the meat.
3. Sear the Meat: After marinating, heat a skillet over medium-high heat. Sear the London broil on all sides for 2-3 minutes per side to develop a flavorful crust. Then transfer it to the slow cooker.
4. Add Vegetables: Arrange the sliced onion, carrot chunks, potato chunks, and garlic cloves around the London broil inside the slow cooker.
5. Add Broth: Pour the remaining 1 cup of beef broth over the meat and vegetables, so the liquid comes about halfway up the sides of the meat.
6. Slow Cook: Cover the slow cooker and cook on low for 6-8 hours, or until the meat is fork-tender and vegetables are cooked through.
7. Rest and Slice: Carefully remove the London broil from the slow cooker and let it rest for 10-15 minutes before slicing thinly against the grain.
8. Make the Sauce (Optional): Strain the cooking liquid into a saucepan. In a small bowl, mix the cornstarch with a few tablespoons of cold water to form a slurry. Bring the strained liquid to a boil, stir in the slurry, and cook until the sauce thickens.
9. Serve: Plate the sliced London broil with the cooked vegetables and drizzle with the thickened savory sauce. Enjoy your hearty slow cooker meal!
