Slow Cooker London Broil With Potatoes and Carrots

What is Slow Cooker London Broil?

Slow Cooker London Broil is a method of cooking a lean cut of beef low and slow until it becomes fork-tender and easy to shred. Because London broil can become tough when cooked quickly, the slow cooker gives the connective tissues enough time to break down, resulting in a tender and flavorful slow cooker beef roast.

I've also made Sous Vide London Broil and Instant Pot London Broil, and while both methods create delicious results, I love this crock pot version for its hands-off convenience and the way the meat slowly absorbs all the rich flavors from the wine, brandy, garlic, and herbs.

The meat braises in a savory mixture of red wine, brandy, Dijon mustard, soy sauce, garlic, and fresh thyme, creating a rich sauce that coats every bite.

Why This Recipe Works

• The long, slow cooking time transforms this lean cut into a truly tender London broil recipe, breaking down the tough muscle fibers while keeping the beef moist and delicious.
• Searing the London broil in a large cast iron skillet before slow cooking creates the Maillard reaction, the beautiful browned crust on the outside of the meat that adds a deeper, richer beef flavor.
• The low and slow crock pot method turns this typically tough cut into a juicy, flavorful fall apart London broil that can be served as a comforting dinner or shredded for incredible roast beef sandwiches.
• The red wine, brandy, coffee, Dijon mustard, and soy sauce create a complex braising liquid with incredible depth of flavor.
• The carrots and potatoes absorb the savory cooking liquid, creating a complete slow cooker roast with potatoes and carrots with very little extra effort.
• It requires only a few minutes of hands-on preparation, making it the perfect easy slow cooker beef dinner for busy weeknights.

Why This Slow Cooker London Broil is Better Than Store-Bought

Store-bought prepared beef roasts often contain excess sodium, preservatives, and generic seasonings. This homemade beef roast slow cooker recipe allows you to control every ingredient while creating a richer, more sophisticated flavor.

The addition of red wine, brandy, fresh herbs, and aromatics makes this taste like something you would order at a restaurant.

What is My Take on a Crock Pot London Broil?

One of the reasons I love making a London broil slow cooker recipe is that it takes an inexpensive cut of beef and transforms it into something truly special.

The addition of coffee is one of my favorite tricks in this recipe. It doesn't make the roast taste like coffee; instead, it enhances the natural richness of the beef and gives the sauce more depth.

If you love turning tougher cuts of beef into comfort food, you should also try this Dutch Oven Beef Stew, another recipe that uses slow cooking techniques to create incredible flavor.

Key Ingredients

• London Broil - London broil is a lean, economical cut of beef that benefits from low and slow cooking methods.
• Red Wine & Brandy - These add richness and help create a deeply flavorful braising liquid.
• Instant Coffee - This secret ingredient intensifies the savory beef flavor without adding a noticeable coffee taste.
• Dijon Mustard & Soy Sauce - They provide acidity, saltiness, and umami that balance the richness of the meat.

How to Get the Best Fall Apart London Broil

• Sear the meat before adding it to the slow cooker for the best flavor.
• Cook on low for 8-10 hours rather than speeding up the process with high heat.
• Keep the beef surrounded by the flavorful cooking liquid.
• Allow the collagen enough time to break down for the perfect tender texture.

Common Mistakes to Avoid

• Skipping the searing step.
• Cooking on high heat, which can leave the meat tough.
• Adding potatoes and carrots too early, causing them to become overly soft.
• Not allowing enough time for the beef to become fork-tender.

Variations

• Use the shredded beef to make sandwiches, tacos, or rice bowls.
• Swap the potatoes for other root vegetables.
• Reduce the leftover cooking liquid on the stove for a thicker gravy.
• Instead of Red Wine & Brandy, you can use sherry, whiskey or bourbon
• Add 1-2 chipotle peppers, hot peppers, or a couple teaspoons of chili powder or cayenne pepper if you want to add spice to this dish.
• Omit the brandy and red wine to keep this alcohol free and substitute with beef broth (try this slow cooker beef bone broth). Add a touch of balsamic vinegar or Worcestershire sauce to add more tangy flavor.

What to Serve With Slow Cooker London Broil

This recipe already includes potatoes and carrots, but if you want to create an even bigger comfort food feast, try serving it with:

• Creamy Mashed Potatoes
• Braised Broccolini
• Classic Lyonnaise Potatoes

These sides pair perfectly with the rich sauce from this slow cooked London broil and help turn it into a memorable meal.

Expert Tips

• Choose a London broil with good marbling whenever possible. The extra fat will help keep the meat more flavorful and tender during the long cooking process.
• Don't skip the sear. Browning the meat before slow cooking creates the Maillard reaction, giving the London broil a richer, deeper beef flavor.
• For even more flavor, dry brine the beef overnight. Season the London broil with salt and let it sit uncovered in the refrigerator overnight before cooking. This helps the seasoning penetrate the meat and improves browning.
• Be patient and avoid opening the lid. Cook the London broil for 8–10 hours on low, or until it easily pulls apart with a spoon. Every time you lift the slow cooker lid, valuable heat escapes and can increase the cooking time.
• Wait to cut your potatoes until you're ready to add them. Cutting them too early can cause them to oxidize and turn brown.
• Let the meat rest before serving. Once the London broil is finished cooking, let it rest for about 10 minutes before slicing or shredding so the juices can redistribute throughout the meat.
• Don't throw away the cooking liquid. Spoon it over the meat and vegetables when serving or save it to keep leftovers moist and flavorful.

Storage, Reheating, Make Ahead & Meal Prep

Store leftovers in an airtight container in the refrigerator for up to 4 days.

Reheat on the stovetop or in the microwave with some of the leftover cooking liquid to keep the meat moist.

You can also freeze this recipe for up to 3 months, making it a great option for preparing a homemade meal ahead of time.
