A tough cut like London broil becomes fork-tender in a crock pot when you give it enough time and the right liquid ratio. Many home cooks struggle with this lean beef, often ending up with a dry, chewy mess. But if you want to know how to cook London broil in crock pot, you are in the right place. This method is almost foolproof, turning a budget-friendly cut into a succulent meal that shreds or slices beautifully. You just need patience and a few simple ingredients.
Let’s get straight to it. The crock pot does all the heavy lifting. You prep the meat, set the timer, and walk away. No constant stirring or watching. It’s perfect for busy days or when you want a hearty dinner without the fuss. I’ll walk you through every step, from picking the right roast to serving it up perfectly.
Why London Broil Works In A Crock Pot
London broil is typically a lean cut from the top round or flank. It’s tough because it comes from a well-used muscle. High-heat cooking methods like broiling or grilling can work, but they require precise timing to avoid overcooking. The crock pot solves this problem with low, slow, moist heat.
The long cooking time breaks down the connective tissues. This turns the chewy fibers into tender, pull-apart meat. The liquid you add prevents it from drying out. It also infuses flavor deep into the beef. This is why slow cooking is the best method for this cut.
How To Cook London Broil In Crock Pot
This is the core of our guide. Follow these steps closely for the best results. The exact keyword “How To Cook London Broil In Crock Pot” is your roadmap to success. Let’s break it down into simple, actionable steps.
Step 1: Choose The Right London Broil
Start with a good piece of meat. Look for a London broil that is about 1.5 to 2.5 pounds. It should be uniform in thickness so it cooks evenly. Check the marbling. A little bit of fat running through the meat adds flavor and moisture. Avoid pieces that look too lean or have large patches of silver skin.
If you buy a pre-packaged London broil, check the sell-by date. Fresh meat is always better. You can also ask your butcher to trim any excess fat or silverskin for you. This saves time at home.
Step 2: Season Generously
Don’t be shy with the seasoning. London broil has a mild flavor, so it needs a good rub. Start with salt and black pepper. Then add garlic powder, onion powder, and a little smoked paprika for depth. You can also use a steak seasoning blend if you prefer.
- Pat the meat dry with paper towels. This helps the seasoning stick.
- Rub the seasoning all over the meat. Press it in firmly.
- Let it sit at room temperature for 20-30 minutes. This allows the flavors to penetrate.
Step 3: Sear The Meat (Optional But Recommended)
Searing is not required, but it adds a huge boost of flavor. The Maillard reaction creates a rich, browned crust. This depth of flavor is missing if you skip this step. Heat a heavy skillet or cast-iron pan over medium-high heat. Add a tablespoon of oil.
- Place the seasoned London broil in the hot pan.
- Sear for 2-3 minutes per side until deeply browned.
- Don’t crowd the pan. Work in batches if needed.
- Transfer the seared meat to the crock pot.
If you are short on time, you can skip searing. The meat will still be tender, but the flavor will be milder. I highly recommend taking the extra 10 minutes for searing.
Step 4: Build The Cooking Liquid
The liquid is crucial for moisture and flavor. You need enough to cover the bottom of the crock pot but not submerge the meat completely. A good ratio is about 1 cup of liquid per 1.5 pounds of meat. Here are some great options:
- Beef broth: Classic and savory. Use low-sodium to control salt.
- Red wine: Adds richness and depth. Use a dry red like Cabernet or Merlot.
- Tomato sauce or crushed tomatoes: Gives a tangy, Italian-style base.
- Worcestershire sauce: A few tablespoons add umami and complexity.
- Water with bouillon: Simple and effective if you have no broth.
Combine your chosen liquids. Add aromatics like sliced onions, garlic cloves, bay leaves, or fresh thyme. Pour the mixture around the meat, not directly over it, to keep the seasoning in place.
Step 5: Cook Low And Slow
This is the most important part. Set your crock pot to low heat. Cooking on low for 6-8 hours is ideal for London broil. High heat for 3-4 hours can work, but the meat may be less tender. Low heat gives the connective tissue time to break down properly.
Do not lift the lid during cooking. Each time you open it, heat escapes and adds 20-30 minutes to the cooking time. Trust the process. The meat will be done when it is fork-tender and easily shreds.
Step 6: Check For Doneness
After 6 hours on low, start checking. Use a meat thermometer for accuracy. London broil is best when cooked to medium-rare to medium, but in a crock pot, it often cooks beyond that. The internal temperature should reach at least 145°F for safety. For shredding, it will be closer to 190°F-200°F.
If the meat is not tender yet, continue cooking. Check every 30 minutes. The meat should pull apart easily with a fork. If it resists, it needs more time.
Step 7: Rest And Slice Or Shred
Once cooked, remove the London broil from the crock pot. Let it rest on a cutting board for 10-15 minutes. This allows the juices to redistribute. If you slice it immediately, the juices will run out and the meat will be dry.
For slicing, cut against the grain. This shortens the muscle fibers and makes each bite tender. For shredding, use two forks to pull the meat apart. It should fall apart easily.
Step 8: Make A Gravy Or Sauce
The leftover liquid in the crock pot is gold. Strain it to remove solids. Skim off any fat. You can use it as is or thicken it into a gravy. To thicken, mix 2 tablespoons of cornstarch with 2 tablespoons of cold water. Whisk this slurry into the hot liquid. Simmer for 2-3 minutes until thickened.
Season the gravy with salt and pepper. Pour it over the sliced or shredded meat. This adds moisture and flavor.
Tips For The Best Crock Pot London Broil
These small details make a big difference. Follow them for consistently great results.
Don’t Overcook It
Even in a crock pot, you can overcook London broil. If you cook it too long, it becomes dry and stringy. Stick to the recommended times. Check for doneness early. Once it is fork-tender, it is done.
Use A Meat Thermometer
This is the most reliable way to know when it’s done. Insert it into the thickest part of the meat. For slicing, aim for 135°F-145°F. For shredding, 190°F-200°F is ideal. Don’t rely solely on time, as crock pots vary.
Add Vegetables Later
If you want to cook vegetables with the meat, add them later in the process. Root vegetables like carrots and potatoes take about 4-5 hours on low. Add them halfway through cooking. Softer vegetables like mushrooms or bell peppers should be added in the last hour.
Deglaze The Pan
After searing, deglaze the hot pan with a splash of broth or wine. Scrape up the browned bits from the bottom. Pour this liquid into the crock pot. It adds incredible flavor.
Flavor Variations To Try
London broil in a crock pot is very versatile. Change the seasoning and liquid to create different cuisines.
Italian Style
- Use tomato sauce, red wine, garlic, and Italian seasoning.
- Serve over pasta or with crusty bread.

Storing And Reheating Leftovers
Leftover London broil is delicious. Store it properly to maintain quality.
Refrigerating
Place the meat and gravy in an airtight container. It will keep in the refrigerator for 3-4 days. The flavors often meld and taste even better the next day.
Freezing
You can freeze the cooked meat for up to 3 months. Wrap it tightly in plastic wrap and then foil. Or use a freezer-safe bag. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat gently to avoid drying out the meat. Use the microwave with a splash of broth. Or reheat in a covered skillet over low heat with some gravy. The crock pot can also be used on the warm setting.
Common Mistakes To Avoid
Even experienced cooks make mistakes. Here are the most common ones and how to avoid them.
- Skipping the sear: This reduces flavor significantly. Don’t skip it.
- Using too much liquid: The meat should not be swimming. Just enough to cover the bottom.
- Lifting the lid too often: Each peek adds cooking time. Resist the urge.
- Not resting the meat: Slicing too soon makes it dry. Always rest.
- Slicing with the grain: This makes the meat chewy. Always slice against the grain.
