Ingredients

• 2 pounds London broil (top round steak)
• 2 tablespoons Olive oil
• 1 teaspoon Salt
• 1 teaspoon Black pepper
• 1 teaspoon Garlic powder
• 1 teaspoon Onion powder
• 3 tablespoons Worcestershire sauce
• 1.5 cups Beef broth
• 2 tablespoons Soy sauce
• 2 tablespoons Balsamic vinegar
• 1 large Yellow onion, sliced
• 4 medium Carrots, peeled and cut into chunks
• 3 large Russet potatoes, peeled and cubed
• 2 sprigs Fresh rosemary
• 2 tablespoons Cornstarch
• 2 tablespoons Water

Directions

Step 1

Pat the London broil dry with paper towels and season both sides with salt, pepper, garlic powder, and onion powder.

Step 2

Heat olive oil in a large skillet over medium-high heat. Sear the London broil for 2-3 minutes on each side until browned. Remove from skillet and set aside.

Step 3

In a slow cooker, layer the sliced onion, carrots, and cubed potatoes at the bottom, creating a bed for the meat.

Step 4

Place the seared London broil on top of the vegetables. Add Worcestershire sauce, beef broth, soy sauce, and balsamic vinegar to the pot.

Step 5

Tuck the rosemary sprigs into the liquid around the meat and vegetables.

Step 6

Cover the slow cooker with the lid and cook on low for 8 hours or until the meat is tender and the vegetables are fully cooked.

Step 7

Once done, remove the meat to a cutting board and let it rest for 5-10 minutes before slicing against the grain into thin strips.

Step 8

To thicken the sauce, mix the cornstarch and water in a small bowl to form a slurry. Stir it into the slow cooker liquid, cover, and cook on high for another 5-10 minutes until thickened.

Step 9

Serve the sliced London broil with vegetables and the thickened sauce spooned over the top. Enjoy!
