The Real Reason I Love Making Crockpot Pepper Steak

You know those nights when the idea of standing over a sizzling pan sounds about as appealing as cleaning behind the fridge? That’s exactly when I pull out my trusty crockpot and make pepper steak. I still remember the first time I tried it—my mom called it “dinner magic” because she just dumped everything in, pushed a button, and, poof, dinner! (She also used a not-so-small splash of soy sauce, but that’s a story for another day.) Plus, on lazy Sundays, the smell is good enough to convince anyone you’ve been working hard, even if you’ve just been watching reruns all day.

Why You’ll Get a Kick Out of This Recipe

I make this when I know my week will be a circus; it’s the sort of meal that lets you read half a book while it cooks. My family goes absolutely wild for the tender slices of beef and the melt-in-your-mouth peppers (especially since I started sneaking in a little extra garlic—my cousin Lisa wasn’t thrilled at first, but even she came around after a second plate). Actually, my only beef with this dish (ha!) is trying to keep enough for leftovers because it really does taste even better the next day. There was that one time I tried to speed things up on high, though, and wound up with tough beef. Not recommended; patience pays off here.

Here’s What You’ll Need (and What You Can Get Away With)

About 500g (a little over a pound) beef sirloin or flank steak – But I’ll be honest, I’ve used stew meat in a pinch. Grandma swore by sirloin, but me? Whatever’s on sale usually makes it in.
2-3 bell peppers, any colors you like – I do like red and yellow for sweetness, but green works totally fine.
1 big onion, sliced – Sweet onions are my thing, but regular yellow is grand.
3 cloves garlic, minced (Or a spoonful of the jarred stuff. No shame!)
1 can (400ml/14oz) diced tomatoes – Fresh tomatoes if you’re feeling fancy, but honestly, the canned ones save time and taste just about as good in here.
3 tbsp soy sauce – I use low sodium but use what you have.
1 tbsp Worcestershire sauce – I used to skip this, but it does add a little somethin’ that makes it taste like takeout, honestly.
1–2 tsp brown sugar – Or honey if you’re out—swapped it once and the kids never noticed.
Salt & black pepper, to taste
Optional: Red pepper flakes for heat, or a dash of smoked paprika (my secret weapon for depth, but that’s just me playing mad scientist)
2 tbsp cornstarch + 2 tbsp cold water, to thicken at the end (You can use flour if you must, but it’s not quite the same.)

Let’s Get This Show on the Road: Directions

Slice your meat and veggies: Cut the beef into strips—try for the thickness of your pinky. I usually aim for half-inch but let’s face it, I never measure exactly. Toss the beef in the slow cooker.
Add peppers and onion: Throw in sliced bell peppers and onion. Don’t stress about chopping everything perfectly; rough chunks work just fine. I sometimes toss in the garlic right on top, or if I’m feeling proper, sauté it for a sec in a pan first—but that’s only if I’m really trying to impress someone.
Mix up the sauce: In a bowl (or honestly, directly in the crockpot if you can’t be bothered), mix the canned tomatoes, soy sauce, Worcestershire, brown sugar, salt, black pepper, and optional spices. Pour over the meat and veggies.
Cook low and slow: Throw the lid on and cook on LOW for about 6-7 hours. Sometimes, if you’re short on time, HIGH for 3-4 hours works—but just remember what I said about tough beef. Low and slow rules the roost here. (This is usually where I sneak a forkful to test the peppers. Quality control is important, right?)
Thicken things up: About 20 minutes before serving, stir the cornstarch and cold water together, then dump it into the crockpot. Stir gently. If it looks weird right now, don’t panic! It comes together with a little patience.

What I’ve Learned the Hard Way (Notes)

If you forget the brown sugar, just use a squirt of ketchup in a panic. It’s not the same, but it does the trick. (Trust me, that’s from last week’s dinner.)
The peppers really do need to go in at the start. I tried adding them halfway in once, thinking they’d stay crisper. They just ended up weirdly chewy, not crunchy.
And honestly, don’t overfill your crockpot! I once tried doubling this and it basically became a beef stew. Still tasty, just… not what you expect.

How I Like to Mix This Up (And One Fail!)

I’ve swapped beef for chicken (just cut the time down to about 4–5 hours on low) and actually it’s pretty tasty—just a different vibe altogether.
Once I used pineapple for a sweet-savory kick. Kind of Hawaiian, I guess? My son loved it, my husband wasn’t convinced. So, your mileage may vary.
The version with sweet chili sauce instead of brown sugar? Don’t do it. It was all sweet, no steak. Some experiments should just stay in the lab.

What You Need (Or What You Can Improvise With)

A slow cooker / Crockpot – But, if you don’t have one, you could use a heavy pot and cook on the stovetop, lowest heat, for a few hours. Keep an eye on it. (Or just invite yourself over to a friend’s house. Not that I’ve done that…)
Cutting board + knife
A mixing bowl – or a big coffee mug, if you’re out of clean bowls (I won’t judge)
Wooden spoon, or whatever you use to stir things up

How to Store (If You Have Any Left!)

Honestly, in my house, this recipe rarely sees the inside of a storage container, but if you get lucky: transfer to an airtight box and stick in the fridge. Good for about 3 days. I *think* it tastes even better the next day, and microwaves like a champ. You can freeze it too, though the peppers get a tad mushy after thawing. (Not the end of the world, just a heads up.)

Serving This Up (My Lazy Side Likes…)

I usually spoon mine over fluffy jasmine rice, mostly because it soaks up every bit of that saucy goodness. Sometimes, when I’m feeling fancy, I’ll slap a fried egg on top—sort of a fusion-y thing I picked up on holiday. My sister eats it with mashed potatoes; I still don’t get it, but to each their own, right?

Pro Tips Learned the Messy Way

I once tried browning the meat first on the stove for “extra flavor”—honestly, didn’t make enough difference to be worth the extra pans to wash. But if you want to, go wild!
Don’t forget to stir the cornstarch with cold water; I skipped that once and ended up with a lumpy mess. (Just had to power through with extra vigorous stirring… not recommended!)
Check your crockpot isn’t set to “keep warm” the entire time—I did once. Six hours later, I had beef-flavored soup. Learn form my mistake!

Burning Questions Folks Have Asked Me (And My Off-the-Cuff Answers)

Can I make this without a crockpot?: Yep, a Dutch oven or any heavy pot on the lowest setting will work. Just keep an eye on it so it doesn’t dry up. Or try this stovetop pepper steak version from Budget Bytes!
What about gluten-free?: Soy sauce usually has wheat, but Tamari works just as well (maybe even better). And cornstarch is gluten-free. You’re golden!
My peppers always end up mushy. What gives?: Sadly, that’s kind of the crockpot trade-off. You can try cutting them thicker, or add them halfway through (though I say it doesn’t help much). Peppers just do what they want, sometimes.
Beef too chewy?: Ah, probably cooked it on high or used a really lean cut. Low and slow, mate. Maybe check out Serious Eats’ guide to slow cooking beef for more science-y detail.
Any way to make it spicier?: Totally! Red pepper flakes or a squirt of Sriracha go a long way. Or try a chopped jalapeño—just wash your hands after, promise?
Can I double this for a crowd?: Technically, yes, but be warned: your crockpot might just throw in the towel halfway through and give you stew. If you try it, maybe use two pots or batch cook.

Oh, random aside—one time I forgot I’d set this going and the neighbors thought I’d opened a new restaurant. Got more visitors that day than on my birthday. Power of slow-cooker smells, I guess!
