Easy Slow Cooker London Broil
I love a great London broil recipe, but my slow-cooked London broil is extra tender and packed full of flavor! It's melt-in-your-mouth tender and perfect for serving for dinner on busy weekdays.
All this London broil needs is a sprinkle of tasty steak seasoning and a quick sear on a skillet; then the crockpot takes over the work! Plus, I added baby potatoes, carrots, and green beans to complete this hearty and comforting dish.
🥘 Ingredients
Pick up a London broil and some fresh veggies, and you're all set! If time allows, season your beef and let it come to room temperature for at least 40 minutes (up to 2 hours) before searing it for the best results.

🔪 How To Cook London Broil In A Crockpot
This dish becomes hands-off after you score, season, and sear your beef! You will need a baking sheet, cast iron skillet, kitchen tongs, a knife, and a crockpot to begin.
A 2.5-pound London broil yields roughly 5 servings. Plus, the tender potatoes, carrots, and green beans already make the perfect side dish!
- Prep. Place your 2.5-pound London broil on a baking sheet. Use a chef's knife to score the London broil in a criss-cross pattern along the top and bottom sides of the beef. Season generously on all sides with 1 tablespoon of steak seasoning (or pot roast seasoning).
- Sear. Heat a cast iron skillet with 1 tablespoon of extra virgin olive oil over medium-high heat and let it heat up until the oil shimmers and is just about to begin smoking. Sear the London broil for 2-3 minutes or until lightly browned on each side. Use tongs to lift and sear the sides and edges as needed.
- Transfer. Transfer the seared London broil into your slow cooker and add the 3 cups of beef broth and 2 tablespoons of butter. Cover and seal with the lid.
- Cook roast. Cook on the low setting for 6-8 hours or on high for 3-4 hours. Add the 1 pound of baby potatoes and ½ pound of baby carrots at the last hour, then add the ½ pound of green beans for the final 30 minutes.
- Cut and serve. Remove the steak from the slow cooker and place it on a cutting board. Slice against the grain or pull apart before serving with the potatoes, carrots, and green beans.
Of course, this London broil roast meal is comforting and filling on its own. However, my wedge salad, Greek pasta salad, or some savory cheese rolls would pair well with it, too! Enjoy!
💭 Angela's Pro Tips & Recipe Notes
- Seasoning and Resting: For optimal flavor, season the London broil and let it rest at room temperature for 40 minutes to 2 hours before cooking. This enhances the meat's flavor and tenderness.
- Liquid Options: You can use 3 cups of beef broth or mix it up with 1 cup of red wine and 2 cups of beef broth for added depth of flavor.
- Making London Broil Gravy: To create a delicious gravy, reserve 1 cup of beef broth. Mix 1 tablespoon of cornstarch with 1 tablespoon of cold water to form a slurry. Whisk this into the beef broth and drippings in a saucepan. Bring it to a boil, then remove from heat. For thicker gravy, increase the cornstarch by 1 tablespoon for each additional cup of liquid. For detailed instructions, see my article on making gravy with cornstarch.
- Slow Cooking Time: Cook on low heat for optimal tenderness (Do not try to speed it up by cooking on high). This slow cooking process allows the flavors to meld and the meat to become tender.
🥡 Storing & Reheating
Wrap any leftover beef (after it's fully cooled) in plastic wrap. Then, place it in an airtight container in the fridge for up to 3-4 days.
Store leftovers in a freezer-safe storage bag. Make sure to wrap it in heavy-duty aluminum foil first to avoid frostbite. Thaw in your refrigerator overnight before reheating, and enjoy it within 3 months.
Reheating
For an individual serving, place your leftovers in the microwave for 1-2 minutes.
For larger amounts, preheat your oven to 375°F (190°C). Place your Lbeef leftovers in a baking dish with a splash of beef broth and cover it with aluminum foil. Bake for 15 minutes or heat through to your liking.

❓ Recipe FAQs
I recommend letting your London broil rest on a cutting board for 5-10 minutes. Slice against the grain before serving with your tender baby potatoes, carrots, and green beans!
A London broil dish is typically made with a top round roast, flank steak, or top sirloin. Any low-fat cut of lean, tough, and thick beef will work in this recipe.
When your London broil is tender and almost falling apart, it's time to take it out of the crockpot. The low and slow method will take 6-8 hours, so you could check with a fork and cook until it reaches that point. It's very important not to overcook a London broil, so make sure to check between those hours.
While it's not absolutely necessary, searing the beef on high heat in a skillet before slow cooking can enhance its flavor and texture.

If I want to do two together should I double the time??
Angela @ BakeItWithLove.com says
You will need to increase the cook time, but it should still cook in 8-9 hours. Check the tenderness of the meat at 8 hours to determine if they need the additional hour. Hope that helps!
Paul Wheeler says
The best London Broil I've ever made, super moist and tasty!
Sharon Turco says
If you’re cooking on low, the meat was great at 8 hours, however, you can’t wait until the final hour to cook your potatoes, carrots and green beans. I had to raise the temp to high for another 2 hours before they were tender. If cooking on low, I would add them half way through.
