1 cup low-sodium beef broth
2 tbsp Worcestershire sauce
2 tbsp soy sauce

Suggested Equipment: Crockpot (slow cooker), large skillet, mixing bowl, whisk, knife, cutting board, measuring cups/spoons, tongs

Step-by-Step Process

Prepare Beef: Pat the London broil dry with paper towels. Rub with olive oil, then season with salt, black pepper, garlic powder, onion powder, and dried thyme. Optionally, sear in a large skillet over medium-high heat for 2–3 minutes per side to lock in flavor.
Prepare Sauce: In a mixing bowl, whisk together beef broth, Worcestershire sauce, soy sauce, and balsamic vinegar. Taste the sauce and adjust with additional soy sauce (for saltiness) or balsamic vinegar (for tanginess) to ensure a balanced flavor. If a thicker sauce is desired, mix cornstarch with 2 tbsp cold water and add to the sauce.
Assemble in Crockpot: Place sliced onion, baby carrots, mushrooms, and minced garlic in the bottom of the crockpot. Lay the seasoned London broil on top. Pour the sauce over the beef and vegetables.
Cook: Cover and cook on low for 7–8 hours or high for 4–5 hours, until the beef is tender and reaches an internal temperature of at least 145°F (medium-rare) or 160°F (medium).
Rest and Slice: Remove the London broil from the crockpot and let it rest for 10 minutes. Slice thinly against the grain for maximum tenderness.
Serve: Arrange sliced beef and vegetables on a white ceramic platter. Spoon sauce over the top or serve on the side. Garnish with fresh parsley or thyme sprigs. Serve hot with mashed potatoes, green beans, red wine, or iced tea.

Tips for Better Crockpot London Broil

Sear the beef before slow-cooking for enhanced flavor and a caramelized crust; skip for a simpler prep.
Taste the sauce before cooking to balance savory, tangy, and umami flavors; adjust with soy sauce or vinegar.
Slice against the grain to ensure tender, easy-to-chew beef.
Use low-sodium broth and soy sauce to control saltiness; adjust seasoning at the end if needed.
Use a white ceramic platter for a vibrant presentation, highlighting the tender beef and colorful vegetables.
Make ahead: Prep and season beef and sauce up to 1 day in advance; store separately in the fridge.
For a thicker sauce, add a cornstarch slurry at the start or simmer the sauce in a saucepan after cooking.
Enhance aesthetic: Present on a white ceramic platter with parsley or thyme for a fresh, inviting look.
