So, About This Pepper Steak in a Crock Pot…

I have to confess: half the reason I started making pepper steak in a crock pot was, well, pure laziness. Years ago, I stumbled home after a long shift and—no joke—just started flinging whatever beef I had, peppers from the week before, and a rather mysterious bottle of soy sauce into my slow cooker. Actually, there was a jazzed-up moment where I sneezed because of the black pepper explosion. But here’s the funny bit: it turned out fantastic (my cousin Lindsey still talks about it whenever I threaten to cook something “fancier”). The crock pot does all the work. You toss things in, go walk the dog, or—let’s be honest—fall down a YouTube rabbit hole. Magic happens.

Why Do I Keep Coming Back to This?

Honestly, I break out this recipe when I want an easy win, or when I’m too frazzled to watch a pot (because if I do, I know I’ll wander off and burn something). My family goes wild for this when the weather dips below “crisp”—the smell alone draws my teenager out of his gaming cave. (He says it “smells like food made by someone who gives a hoot.”) Sometimes, if I’m short a pepper or two, I’ll just make it anyway, because you do you.

What You’ll Need (But There’s Wiggle Room)

1.5 to 2 lbs beef sirloin, sliced into strips (flank steak is great but, full disclosure, I’ll use stew beef if that’s what’s on hand)
2-3 bell peppers, sliced—any color (red is prettiest, but green is cheaper; yellow’s what I use if there’s a sale)
1 onion, cut into chunky slices (or a handful of those frozen diced ones if you can’t be bothered – they work fine)
1/4 cup soy sauce (I grew up with Kikkoman, but the generic stuff has saved me a trip more than once)
2 cloves garlic, minced (powder is okay—no judgement)
1-2 tbsp tomato paste (actually, ketchup works if you’re out; I won’t judge)
1 cup beef broth (water plus a bouillon cube is honestly what I use half the time)
1 tsp black pepper (I’ll be honest: I rarely measure this. More is better.)
1-2 tbsp cornstarch mixed with 2 tbsp water—for thickening at the end
Optional: A splash of Worcestershire sauce, a pinch of crushed red pepper, a handful of mushrooms (if I find them lurking in the fridge), or literally any green vegetable your household will tolerate

How I Actually Make This (Try Not to Judge My Process)

Slice and Dice: Cut up the beef and veggies. Sometimes I do this while chatting on the phone; sometimes I just kind of hack away and hope for the best. (Uniform cuts? Ambitious. Tasty? Always.)
Layer It In: I toss the beef in first, then scatter those peppers and onions on top. If you add mushrooms, put them above the beef but below the peppers — or don’t, it’s not a science.
Mix the Sauce: Stir together the soy sauce, garlic, tomato paste, beef broth, pepper, and anything else saucy, then pour it all over what’s in the pot. At this point, it sometimes looks… odd. That’s normal.
Cook It Low and Slow: Lid on, set the crock pot to low for about 6-7 hours, or high for 3-4 if you’re behind schedule (I’ve done both—results are very close). Go off and live your life.
Thicken It Up: About 30 mins before serving, stir up the cornstarch and water, then pour it in. Give it a stir. It looks weird at first—trust me, the sauce thickens up pretty quick. This is honestly when I sneak a taste, just because I can’t resist.
Shut It Down: Once it looks glossy and your kitchen smells better than that stir fry place downtown, you’re basically done. Maybe give it a gentle stir, then scoop it out.

Things I’ve Learned the Hard Way (Notes from My Mishaps)

Cutting the peppers too small? Mushville. I go chunky now.
If you forget the garlic at the start, just stir some powder in at the end, nobody will know.
Don’t bother browning the beef first unless you have a spare 15 minutes and a grumpy chef hovering (I tried it and honestly, not worth the drama).
Leftover sauce is super on rice the next day. Or, if the fridge gremlins get to it, toast.

My Pepper Steak Experiments (Some Wild, Some Winning)

I tried it once with pineapple for a “sweet and sour” twist. Regrets. My husband calls it “that barbecue disaster” (but the kids didn’t hate it!).
Throwing in broccoli in the last hour actually wins rave reviews at my table.
Swapping soy sauce for coconut aminos works if you want a gentler, less salty taste. Not my favorite, but Aunt Mags swears by it.
I even saw this version on Budget Bytes, and stole their mushroom idea. Cheers to them!

If You Don’t Have a Crock Pot (My Secret Workaround)

Hey, you don’t actually need a fancy slow cooker. Once, when my crock pot was holding chili for a potluck (not my brightest planning), I just made this in a Dutch oven on the stovetop, heat on low, lid mostly on, stirring every so often. The magic is the slow cook, not the tool.

How Long Does This Stuff Keep?

Officially? Probably 2-3 days, tightly covered in the fridge. But honestly, in my house it never lasts more than a day—especially if there’s decent bread nearby. I’ve kept leftovers in an airtight container, warmed them up in the microwave, and they’re still lovely. If you want to freeze, portion it out and reheat in a pot gently, maybe add a splash of broth to revive it.

Serving This Up (Here’s How We Do It)

Rice is the classic. Steamed white, sticky jasmine, even brown if you feel virtuous. But I’ve also served this over buttered egg noodles (midwestern move, I know), or—get this—tucked it into a soft wrap with crunchy lettuce. Sunday nights, we do a “serve yourself” setup. Secret tip: try it with leftover mashed potatoes at least once!

Pro Tips (Learned the Hard Way, Trust Me)

I once tried to rush this by cranking the heat. Nope—it ended up tough, like chewing sneaker leather. Low and slow’s the way.
Don’t skip the cornstarch step—it’s tempting, but if you want that glisteny sauce that clings to rice, it’s necessary.
If you think it’s too salty, add a splash of water or a pinch of sugar (not both, though, unless you love chaos).

Questions I Actually Get (and Some I’ve Asked Myself)

“Can I make this with chicken?” Well, I’ve tried it – the flavor is a bit different, but yes! Just lower the cook time to about 4 hours on low, or it’ll get dry.
“Is there a gluten-free version?” For sure! Use tamari instead of soy sauce. Cornstarch should be fine for most, but check the package just in case.
“Can it be made the night before?” Absolutely. I think it tastes better the next day (something about magic overnight fridge time?). Just reheat gently.
“What if I don’t have tomato paste?” Use ketchup. Or, on one desperate evening, I used a splash of barbecue sauce. It was actually pretty good—messier though.
Oh! And if you’re wondering what crock pot I use… it’s this basic Crock-Pot from Amazon. No bells. No whistles. But it’s hanging in there after too many sticky, saucy nights.

And hey, if you make this, let me know how it turns out (especially if you try any wild variations—I love a good kitchen adventure). It’s the kind of meal that makes the house feel cozy. Or maybe that’s just the steam from the cooker fogging up my glasses.
