Crockpot London Broil

I love a Dutch oven or grilled London broil, but my crock pot recipe makes an even more tender London broil. My slow cooking method makes for a super tender roast and takes very little effort, making it perfect for dinner on busy weekdays.

All this London broil crock pot recipe needs is a sprinkle of steak seasoning and a quick sear in a skillet before your slow cooker takes over the work. Plus, I added baby potatoes, carrots, and green beans to complete this hearty and comforting meal.

🥘 Ingredients

• London Broil - You could use any cut of beef between 2-3 pounds, whatever beef roast you can find at your local grocery store.
• Steak Seasoning - Your favorite steak seasoning, my homemade steak seasoning, (or my pot roast seasoning).
• Cooking Oil - I used beef tallow, or you can use your preferred high-heat cooking oil.
• Beef Broth - Beef broth or stock to keep the roast moist in the slow cooker.
• Butter - The butter goes right on top of the roast to melt in the crockpot, keeping the beef moist and flavorful.

Optional Veggies

• Baby Potatoes - A bag of baby potatoes (red, yellow, or mixed potatoes).
• Baby Carrots - Whole baby carrots or sliced large carrots. I never peel my carrots, that's totally up to you.
• Green Beans - Fresh or frozen green beans make an excellent addition. No need to thaw them first.

🔪 How To Cook London Broil In A Crockpot

This roast becomes hands-off after you score, season, and sear your beef. You will need a baking sheet, a large skillet, kitchen tongs, a knife, and a crockpot.

A 2.5-pound London broil yields roughly 5 servings. Plus, if you opt for the veggies the tender potatoes, carrots, and green beans make the perfect side dish.

Step 1: Prep. Place your 2.5-pound (1.13 kilograms) 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 (photos 1, 2). Season generously on all sides with 1 tablespoon of steak seasoning or pot roast seasoning (photo 3).

Step 2: 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 (photo 4).

Step 3: Transfer. Transfer the seared London broil into your slow cooker, pour the 3 cups of beef broth over the top, and add 2 tablespoons of butter (photos 5, 6). Cover and seal with the lid.

Step 4: Cook roast. Cook on the low setting for 6-8 hours or on high for 3-4 hours. If using vegetables, add 1 pound (453.59  grams) of baby potatoes and ½ pound (226.8 grams) of baby carrots at the last hour, then add ½ pound (226.8 grams) of green beans for the final 30 minutes.

Step 5: Cut and serve. Remove the steak from the slow cooker and place it on a cutting board. It should be fall-apart tender and easy to shred, or you can slice against the grain before serving with the potatoes, carrots, and green beans.

💭 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. 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 beef 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.

❓ How Long Should London Broil Rest Before Slicing?

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.

❓ What Cut Of Meat Should I Use For My Crockpot London Broil?

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.

❓ How Do I Know When My Crockpot London Broil Is Done?

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.

❓ Is it necessary to sear the beef before placing it in the Crockpot?

While it's not absolutely necessary, searing the beef on high heat in a skillet before slow cooking can enhance its flavor and texture.
