When I make slow-cooker pepper steak, I’m usually after a dinner that feels comforting but doesn’t demand much hands-on time. The beef turns tender as it cooks, the peppers soften without disappearing, and the sauce brings everything together in a way that feels a lot like takeout at home. If you’ve liked versions such as this hearty pepper steak variation, you’ll probably appreciate how well this slow-cooker method delivers deep flavor with very little effort.
Why you’ll love this dish
This recipe hits a sweet spot for busy nights: it uses simple ingredients, stretches well over rice, and gives you that savory-sweet pepper steak flavor without standing over the stove. It’s also the kind of meal that works for almost everyone at the table, since the beef gets fork-tender and the peppers bring color and freshness.
“This is the kind of dinner that feels like a win: minimal prep, big flavor, and leftovers that taste even better the next day.”
It’s especially good when you want a family dinner that looks like you worked hard, even though the slow cooker did most of the job. For anyone who likes planning ahead, it also reheats nicely and pairs well with a variety of sides.
Preparing Slow-Cooker Pepper Steak
The process is straightforward: layer the steak and vegetables in the slow cooker, whisk together the savory sauce, pour it over everything, and let time do the work. The cornstarch helps the sauce thicken as it cooks, so by the end you get a glossy, spoon-coating sauce instead of something thin or watery.
If you want a slightly different take on the same comfort-food idea, this pepper steak version with a slightly different balance of flavors is another helpful reference for comparing texture and seasoning.

Ingredients
Gather these items
- 1 pound flank steak, sliced into thin strips
- 1 large green bell pepper, sliced
- 1 large red bell pepper, sliced
- 1 onion, sliced
- 2 cloves garlic, minced
- 1 cup beef broth
- 1/4 cup soy sauce
- 2 tablespoons cornstarch
- 1 tablespoon Worcestershire sauce
- 1 tablespoon olive oil
- Salt and pepper to taste
A few quick notes: flank steak is ideal because it becomes tender when cooked low and slow, but sirloin can work too. If you prefer a slightly sweeter sauce, you can add a small spoonful of brown sugar, though it isn’t necessary.
Directions
Cooking method
- Add the sliced flank steak, bell peppers, onion, and garlic to the slow cooker.
- In a separate bowl, whisk together the beef broth, soy sauce, Worcestershire sauce, and cornstarch until the mixture looks smooth.
- Pour the sauce over the beef and vegetables.
- Drizzle the olive oil on top, then season lightly with salt and pepper.
- Cover and cook on low for 6 to 8 hours, or on high for 3 to 4 hours, until the beef is tender.
- Serve hot over rice or noodles.
Best ways to enjoy it
This pepper steak is at its best when spooned over fluffy white rice, but it also works well with brown rice, lo mein-style noodles, or mashed potatoes if you want something extra cozy. For a fresher plate, add a side of steamed broccoli, snap peas, or a simple cucumber salad to balance the rich sauce.
If you’re serving guests, try placing the pepper steak over a bed of rice and finishing it with sliced green onions or sesame seeds. That small garnish makes the dish feel restaurant-style without adding extra work.
Storage and reheating tips
Store leftovers in an airtight container in the refrigerator for up to 3 to 4 days. For the safest results, refrigerate the pepper steak within 2 hours of cooking. When reheating, warm it gently on the stove or in the microwave until it’s steaming hot throughout.
You can also freeze it for up to 2 to 3 months. For the best texture, let it cool first, then freeze in portions with some of the sauce. Thaw overnight in the fridge before reheating.
Helpful cooking tips
A few small details make a big difference here. Slice the steak against the grain so it stays tender after cooking. If your peppers tend to soften quickly, cut them into thicker strips so they hold their shape better in the slow cooker. Also, whisk the sauce well before pouring it in so the cornstarch doesn’t clump.
If your slow cooker runs hot, check the steak a little early. You want it tender, not falling apart into shreds unless that’s the texture you prefer.
Creative twists
You can adjust this recipe in a few easy ways without losing the spirit of the dish:
- Add mushrooms for an earthier flavor.
- Swap flank steak for sirloin or chuck roast cut into strips.
- Use tamari instead of soy sauce for a gluten-free version.
- Stir in crushed red pepper if you like a little heat.
- Add pineapple chunks for a sweeter, more tangy variation.
For a deeper savory profile, some home cooks like to finish it with a splash of sesame oil right before serving. Just keep it light so it doesn’t overpower the sauce.
Common questions
Can I cook this on high instead of low?
Yes. Cook it on high for about 3 to 4 hours, or until the beef is tender. Low and slow usually gives the best texture, but high works well when you’re short on time.
Can I use a different cut of beef?
Yes, sirloin is a good substitute, and chuck roast can also work if sliced thinly. Flank steak is still a strong choice because it becomes tender without turning greasy.
How do I keep the sauce from getting too thin?
Make sure the cornstarch is fully whisked into the broth before adding it to the slow cooker. If you want it thicker at the end, you can also let the lid stay off for a few minutes or stir in a small cornstarch slurry near the end of cooking.
Is this recipe good for meal prep?
Absolutely. It reheats well and the flavor often improves by the next day. Just store it in airtight containers and keep the rice or noodles separate if you want the best texture.
