Slow Cooker London Broil
Description
This Slow Cooker London Broil starts by seasoning and searing the beef to develop a flavorful crust, which helps preserve juices and adds depth to the dish. The beef is then placed in a slow cooker along with quartered onions, minced garlic, ground thyme, red pepper flakes, Worcestershire sauce, red wine or beef broth, condensed cream of mushroom soup, and unsalted butter. The mixture stews on low or high heat for several hours to develop a tender texture and rich flavor. Carrots and mini red potatoes are added later in the cook cycle so they remain firm without overcooking. An optional cornstarch slurry can be used at the end to thicken the liquid into a gravy. This dish comes together as a complete one-pot meal, where the long cooking softens the beef and melds all flavors into a comforting, hearty dinner that can be adapted in seasoning and timing based on personal preferences or ingredient availability.
Ingredients
- 5 lbs London Broil beef beef cut
- 3 tablespoons canola oil
- 1 onion quartered
- 5 cloves garlic minced
- 1/2 teaspoon thyme ground
- 1/4 teaspoon red pepper flakes
- 1/4 teaspoon salt or to taste
- 1/4 teaspoon black pepper or to taste
- bay leaf optional, few
- 2 tablespoons Worcestershire sauce
- 1 cup red wine or beef broth
- 2 cups beef broth
- 1 can (10 1/2 oz) cream of mushroom soup condensed
- 4 tablespoons butter diced, unsalted
- 10 mini red potatoes cut in half
- 1 1/2 cups carrot cut into 2" chunks or use whole mini carrots
Optional Cornstarch Slurry:
- 3 tablespoons cornstarch
- 1/4 cup water
Instructions
- First, pat dry beef with paper towels and season with salt and pepper on each side.
- Place a large cast iron pan or Dutch oven on the stove over medium-high heat. Once hot, add oil, and sear beef on all sides for about 1-2 minutes on each side, until golden brown in color.
- Transfer the meat to an 8 qt slow cooker. Add the rest of the ingredients, except carrots and potatoes, and add the butter last on top of the beef. Gently stir to combine.
- Put the lid on the crockpot and cook for 5-6 hours on high, or 8-10 hours on low.
- If you want to add carrots and potatoes, add them to the slow cooker when there are 2-3 more hours of cooking left. Cover and continue cooking until tender.
Optional Cornstarch Slurry:
- Combine cornstarch and water in a small bowl until cornstarch is fully dissolved. Add the mixture to the slow cooker when one hour of cooking is left. Gently stir. This will thicken the gravy. Check after 30 minutes, and if needed add more.
- Once done, transfer the London Broil to a serving platter and carve. Arrange the potatoes and carrots around the roast. Garnish with fresh chopped parsley and drizzle with the gravy before serving.
Notes
- Searing the beef before slow cooking enhances flavor and retains juices, resulting in better texture.
- Use whole baby potatoes to maintain their shape during the long cooking time.
- Red wine can be substituted with balsamic vinegar or beef broth if preferred.
- Add carrots and potatoes during the last 2-3 hours of cooking to avoid over-softening.
- Adjust cooking time for smaller cuts of meat to prevent overcooking; monitor near the end.
