Ingredients
Scale
Marinade and Meat
- 2 pounds London broil
- ¼ cup low-sodium soy sauce
- 1 Tbsp. balsamic vinegar
- 1 Tbsp. Worcestershire sauce
- ¾ cup beef broth (for marinade)
- 1 Tbsp. brown sugar
- ½ tsp. dried rosemary
- ½ tsp. dried thyme
- ¼ tsp. black pepper
- 1 Tbsp. olive oil
Vegetables and Cooking Liquid
- 1 ¼ cup beef broth (remaining)
- 1 medium onion, sliced
- 2 carrots, peeled and cut into chunks
- 2 potatoes, cut into chunks
- 4 garlic cloves
Optional
- 1 Tbsp. cornstarch (for thickening)
Instructions
- Prepare the Marinade: 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 a flavorful marinade.
- Marinate the Meat: Place the London broil in a resealable plastic bag or shallow dish and pour the marinade over the meat. Ensure the meat is evenly coated. Seal or cover, then refrigerate for at least 4 hours, preferably overnight, to infuse flavors deeply.
- Sear the Meat: Heat a skillet over medium-high heat and sear the London broil on all sides for 2-3 minutes per side. This locks in the flavors and adds a rich crust. Transfer the seared meat to the slow cooker.
- Add Vegetables: Arrange the sliced onion, carrot chunks, potato chunks, and garlic cloves around the London broil inside the slow cooker evenly to ensure even cooking.
- Pour Cooking Liquid: Pour the remaining 1 ¼ cup of beef broth over the meat and vegetables until the liquid reaches about halfway up the sides of the meat.
- Slow Cook: Cover and cook on low for 6-8 hours until the meat is fork-tender and vegetables are soft.
- Rest the Meat: Remove the London broil from the slow cooker and let it rest for 10-15 minutes before slicing thinly against the grain to maintain tenderness.
- Thicken the Sauce (Optional): Strain the liquid from the slow cooker into a saucepan. In a small bowl, mix the cornstarch with a few tablespoons of cold water to create a slurry. Bring the strained liquid to a boil, stirring constantly, and add the slurry until the sauce thickens to desired consistency.
- Serve: Plate the sliced London broil with the cooked vegetables and drizzle with the thickened savory sauce. Enjoy your hearty and delicious slow-cooked meal!
Notes
- Marinate overnight if possible to intensify the flavor.
- Searing the meat before slow cooking adds depth of flavor but can be skipped for convenience.
- Use low-sodium beef broth to control salt levels.
- Feel free to substitute vegetables like parsnips or turnips if desired.
- The sauce can be thickened with cornstarch or left as a thinner broth depending on preference.
