Slow Cooker London Broil Recipe

Introduction

This Slow Cooker London Broil is an easy and flavorful meal that tenderizes the meat to perfection while cooking low and slow. Marinated in a savory blend of soy sauce, balsamic vinegar, and herbs, it pairs beautifully with hearty vegetables for a comforting dinner.

Ingredients

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

Instructions

1. Step 1: In a medium bowl, whisk together the 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. Pour the marinade over the meat, ensuring it is evenly coated. Seal or cover and refrigerate for at least 4 hours, preferably overnight.
3. Step 3: Heat a skillet over medium-high heat. Sear the London broil on all sides for 2-3 minutes per side to lock in the flavors. Transfer the meat and marinade to the slow cooker.
4. Step 4: Arrange the sliced onion, carrot chunks, potato chunks, and garlic cloves around the London broil in the slow cooker.
5. Step 5: Pour the remaining 1 cup of beef broth over the meat and vegetables. The liquid should reach about halfway up the side of the meat.
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 for 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 make a slurry, then add it to the liquid. Bring to a boil while stirring until the sauce thickens.
9. Step 9: Serve the sliced London broil with the cooked vegetables and drizzle with the savory sauce. Enjoy!

Tips & Variations

• For extra flavor, marinate the meat overnight to fully develop the taste.
• You can substitute the potatoes with sweet potatoes for a sweeter twist.
• If you prefer a thicker sauce, add more cornstarch slurry gradually until desired consistency is reached.
• Use fresh herbs instead of dried for a brighter flavor.

Storage

Store leftover London broil and vegetables in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or on the stovetop until warmed through. The sauce can be reheated separately and poured over when serving.

FAQs

Can I cook London broil without searing it first?

Searing adds flavor by creating a caramelized crust and helps lock in juices, but you can skip this step if short on time. The slow cooker will still tenderize the meat, although the flavor might be slightly less rich.

What cut of meat is London broil?

London broil is generally a method of preparation rather than a specific cut, often using flank steak or top round. These lean cuts benefit from marinating and slow cooking to become tender and flavorful.

Notes

• Marinating overnight enhances the flavor and tenderness of the meat.
• Searing the meat before slow cooking locks in juices and adds depth of flavor.
• Cut vegetables into uniform chunks to ensure even cooking.
• Resting the meat after cooking allows juices to redistribute for better texture.
• The cornstarch slurry is optional but recommended for a thicker, more flavorful sauce.
