London broil has a reputation problem.
Cook it the normal way and you get a chewy, sad slab of meat that fights back with every bite. Cook it in the crock pot and something completely different happens.
It falls apart with a fork.
I didn’t believe this the first time either. London broil is a lean cut. Lean cuts and slow cookers aren’t usually best friends. But something about the low, slow heat breaks down all that tough connective tissue until you’re left with meat that’s soft, rich, and honestly a little unfair to every other pot roast I’ve made.
This is the recipe I make when I want a Sunday dinner but I’m not spending my Sunday standing at a stove.
What You’ll Need
For the London Broil:
- 2 to 2.5 lb London broil (top round works great here)
- 1 tablespoon olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon smoked paprika
- 1 large yellow onion, sliced
- 4 garlic cloves, minced
- 1 cup beef broth
- 2 tablespoons Worcestershire sauce
- 1 tablespoon tomato paste
- 2 sprigs fresh rosemary (or 1 tsp dried)
- 2 sprigs fresh thyme (or 1 tsp dried)
For the gravy (optional but you’ll want it):
- 2 tablespoons cornstarch
- 2 tablespoons cold water
Tools You’ll Need
- A 6-quart slow cooker
- A cast iron skillet (or any heavy skillet)
- A meat thermometer
- Tongs
- A small mixing bowl for the cornstarch slurry
Instructions
1. Sear the meat first.
Don’t skip this step. Pat the London broil completely dry, rub it with olive oil, then coat it in the salt, pepper, garlic powder, onion powder, and smoked paprika.
Heat your skillet on high until it’s practically smoking. Sear the meat for 2 to 3 minutes per side, just until you get a deep brown crust.
You’re not cooking it through here. You’re building flavor.
2. Build the base.
Add your sliced onion to the bottom of the slow cooker. Lay the minced garlic on top.
3. Add the seared meat.
Place the London broil right on top of the onions and garlic.
4. Pour in the liquid.
Whisk together the beef broth, Worcestershire sauce, and tomato paste. Pour it around the meat, not over the crust you just built.
Tuck the rosemary and thyme sprigs into the liquid.
5. Cook low and slow.
- Low setting: 7 to 8 hours
- High setting: 4 to 5 hours
You’ll know it’s done when a fork twists into it with almost no resistance.
6. Make the gravy.
Remove the meat and set it aside to rest. Strain the liquid into a saucepan and bring it to a simmer.
Mix the cornstarch with cold water until smooth, then whisk it into the simmering liquid. It’ll thicken in about 2 minutes.
7. Shred or slice.
Shred the meat with two forks, or slice it thin against the grain if you want it to look more like a classic London broil.
Pour that gravy over everything. This is the part I look forward to all day.
Pro Tips
- Slice against the grain, always. Even though this cut goes soft in the crock pot, cutting with the grain will still give you stringy, chewy bites. Look for the direction of the muscle fibers and cut across them.
- Don’t skip the sear. I tried skipping it once to save time. The flavor difference was honestly kind of shocking, and not in a good way.
- Use a meat thermometer for peace of mind. You’re going well past the standard 145°F here since you want it fall-apart tender, not medium-rare. Aim for 205°F internally for that shredding texture.
- Let it rest before cutting. Ten minutes, minimum. Cutting into it too early lets all that liquid run right out onto your cutting board instead of staying in the meat.
- Salt it the night before if you can. A quick overnight salt makes a real difference in how deep the flavor goes.
Substitutions and Variations
| Original | Swap | Why It Works |
|---|---|---|
| London broil (top round) | Chuck roast | More marbling, still shreds beautifully |
| Beef broth | Red wine + broth (half and half) | Adds a deeper, more restaurant-style flavor |
| Worcestershire sauce | Soy sauce + a splash of balsamic | Similar umami punch |
| Fresh herbs | Dried herbs | Use a third of the amount |
| Cornstarch slurry | Flour and butter roux | Slightly richer, more traditional gravy |
If you want it spicier, add a diced jalapeño with the onions. If you want it more like a pot roast, toss in quartered potatoes and carrots during the last 2 hours of cooking.
Make Ahead Tips
You can season the meat and sear it up to 24 hours ahead, then store it in the fridge until you’re ready to load the crock pot.
The finished dish also reheats beautifully, which brings me to leftovers.
Leftovers and Storage
Store leftover London broil in an airtight container with the gravy for up to 4 days in the fridge.
It also freezes well. Shred it first, then freeze in a freezer bag with a bit of the gravy for up to 3 months.
To reheat, add a splash of broth and warm it low and slow, either on the stove or in the microwave in 30-second bursts. This keeps it from drying out.
Leftover ideas:
- French dip sandwiches with the leftover gravy as au jus
- Shredded beef tacos with a squeeze of lime
- Beef and rice bowls with the gravy poured over top
- A quick beef and noodle soup using the extra broth

This is a naturally lean, high-protein dinner as long as you trim any visible fat before searing.
Meal Pairing Suggestions
This dish is rich, so it pairs best with something bright or starchy to balance it out.
- Creamy mashed potatoes
- Roasted green beans with lemon
- A simple arugula salad with vinaigrette
- Crusty bread for soaking up the gravy
FAQ
Can I cook this from frozen? It’s not recommended. Slow cookers can take too long to bring frozen meat to a safe temperature, which increases food safety risk. Thaw it fully first.
Why is my London broil still tough? It usually needs more time, not less. This is a cut that actually gets more tender the longer it cooks, so if it’s chewy, give it another hour.
Can I make this in an Instant Pot instead? Yes. Use the pressure cook setting for about 60 to 70 minutes with a natural release.
What’s the difference between London broil and a regular steak? London broil isn’t actually a specific cut of beef. It’s a cooking method traditionally applied to top round, flank, or sirloin tip. That’s part of why it can be confusing at the meat counter.
Do I need to sear the meat first? You don’t have to, but you’ll lose a noticeable amount of flavor. If you’re short on time, at least give it a quick sear.
Wrapping Up
This is one of those recipes that quietly becomes a regular in your rotation without you really planning it that way.
It’s low effort, it makes the whole house smell incredible by hour three, and it turns a cut of meat that intimidates a lot of home cooks into something completely foolproof.
Give it a try this week, and when you do, come back and leave a comment letting me know how it turned out. If you tried any of the swaps or have a question about timing, I’d genuinely love to hear it.
