Pepper steak is one of those dishes that looks like it takes a lot of effort. Tender strips of beef, glossy ginger-soy sauce, sweet peppers and onions — it tastes like something you’d order at a Chinese restaurant.
This version takes 10 minutes of prep and a slow cooker. No searing, no marinating, no standing at the stove. Just dump everything in, walk away, and add the peppers and cornstarch at the end so they stay crisp and the sauce thickens and gets glossy.
About 33g of protein per serving from the beef alone. Serve it over rice, and you’ve got a complete weeknight dinner that the whole family will eat.
One thing worth knowing: the two-stage pepper add is the only step you can’t skip. Add two-thirds of the peppers at the start and let them melt into the sauce to add sweetness and body. Add the last third during the final 30 minutes so it stays bright and slightly crisp. That contrast is what makes this taste like real pepper steak, not a stew.
Why This Crockpot Pepper Steak Works
It’s a true dump-and-go recipe. No searing, no marinating, no stovetop steps. Everything except the peppers and cornstarch goes into the slow cooker at once.
Chuck roast or stew meat becomes fall-apart tender. Chuck is heavily marbled with connective tissue that breaks down during a long cook. After 6–8 hours on LOW, the beef is fork-tender, and the broth is rich.
The two-stage pepper add is the texture trick. Cook two-thirds of the peppers with the beef so they melt into the sauce. Add the last third during the final 30 minutes so they stay crisp and colorful.
Cornstarch at the end makes the sauce glossy. The braising liquid is thin on its own. A cornstarch slurry during the last 10 minutes turns it into a sauce that clings to every piece of beef and pepper.
The sauce is built from pantry staples. Soy sauce, beef broth, brown sugar, garlic, ginger, and a splash of rice vinegar. No specialty ingredients, no takeout menu required.
It’s family-friendly. The sauce is savory and slightly sweet, not spicy. Kids eat it without complaint, and adults go back for seconds.
It’s cheap. Beef chuck, bell peppers, onions, and pantry sauces. About $2.50 per serving.
It’s a complete meal with rice. Serve it over jasmine or white rice, and dinner is done. Add steamed broccoli for a full plate.
It’s meal-prep and freezer-friendly. Portion it over rice into containers and refrigerate for 4 days or freeze for 3 months.
Crockpot Pepper Steak
Slow-cooked tender beef with green peppers, onions, and a rich ginger-soy sauce. Serve over rice for an easy weeknight dinner.
Ingredients
- 2 lbs beef chuck roast, cut into ¼-inch strips (or 2 lbs stew meat)
- 1 large yellow onion, sliced into wedges
- 4 cloves garlic, minced (or 1 tbsp jarred minced garlic)
- 1 tbsp grated fresh ginger (or 1 tsp ground ginger)
- 1 cup low-sodium beef broth
- ¼ cup low-sodium soy sauce or tamari
- 2 tbsp brown sugar
- 1 tbsp rice vinegar
- ½ tsp black pepper
- 3 large green bell peppers (or a mix of green, red, and yellow), sliced into strips
- 2 tbsp cornstarch mixed with 2 tbsp cold water
- Cooked jasmine or white rice, for serving
- Sesame seeds and sliced green onions, for garnish (optional)
Instructions
1. Load the slow cooker. Add the beef, onion, garlic, ginger, beef broth, soy sauce, brown sugar, rice vinegar, and black pepper to a 6-quart slow cooker. Stir gently to combine.
2. Add two-thirds of the peppers. Add two-thirds of the sliced bell peppers to the slow cooker and stir. Save the remaining third for later — they go in during the last 30 minutes so they stay crisp.
3. Slow cook. Cover and cook on LOW for 6–8 hours or on HIGH for 3–4 hours, until the beef is fork-tender.
4. Add the remaining peppers. Stir in the remaining sliced bell peppers. Cover and cook on HIGH for 20–30 minutes, until they're tender-crisp and bright green.
5. Thicken the sauce. Whisk the cornstarch and cold water together in a small bowl. Stir the slurry into the slow cooker. Cover and cook on HIGH for 5–10 minutes, until the sauce thickens and turns glossy.
6. Taste and serve. Taste and add more soy sauce for salt, brown sugar for sweetness, or rice vinegar if it tastes flat. Serve over jasmine rice and garnish with sesame seeds and sliced green onions.

Tips for the Best Crockpot Pepper Steak
Use chuck roast or stew meat. Chuck has the marbling and connective tissue that break down into fork-tender beef during a long cook. Sirloin, round, and loin are too lean and will dry out.
Cut the beef into uniform strips. Even pieces cook evenly. ¼-inch strips are the sweet spot — thin enough to be tender, thick enough to hold their shape.
The two-stage pepper add is the only step you can’t skip. Add two-thirds at the start and let it melt into the sauce. Add the last third during the final 30 minutes to keep them crisp and colorful.
Use low-sodium soy sauce. Regular soy sauce plus the beef broth can make the dish too salty. Low-sodium gives you control, and you can always add more at the end.
Don’t skip the cornstarch slurry. The braising liquid is thin on its own. A slurry during the last 10 minutes turns it into a glossy sauce that clings to every piece of beef and pepper.
Stir in the cornstarch slowly. Pour it in a steady stream while stirring. Dumping it in all at once can cause clumps.
For a thicker sauce, add another slurry. Mix 1 tsp cornstarch with 1 tbsp cold water, then stir it in. Cook another 5 minutes.
Season at the end, not the beginning. Soy sauce, broth, and rice vinegar all contribute sodium. Taste before adding more salt.
Serve over jasmine rice. The sauce is the best part. The rice soaks it up and turns it into a complete meal.
For meal prep, portion the beef and sauce over rice. Refrigerate 4 for the week and freeze the rest. Reheat in the microwave for 90 seconds with a splash of water.
Easy Variations
Pepper Steak With Tomatoes
Add 1 can (14 oz) of diced tomatoes (undrained) along with the broth. It’s a slightly tangier, more classic diner-style version. If you want it thicker, increase the cornstarch slurry to 1½ tablespoons.
Steak and Peppers Crockpot (Extra Peppers)
Double the peppers and use a mix of green, red, yellow, and orange. The extra peppers make it more vegetable-forward, and the colors look beautiful on the plate. Add the extra peppers in the last 30 minutes.
Ground Beef Pepper Steak
Swap the chuck roast for 1½ lbs of lean ground beef. Brown it in a skillet first, then add everything to the slow cooker and cook on LOW for 3–4 hours. It’s faster, cheaper, and the ground beef makes it heartier.
Pepper Steak With Mushrooms
Add 8 oz of sliced cremini or button mushrooms along with the onion. They add depth and umami, making the dish feel more substantial.
Storage and Food Safety
Refrigerator: Store the beef and sauce in an airtight container for up to 4 days. Store rice separately for the best texture.
Freezer: Cool completely, portion into freezer-safe containers with the sauce, and freeze for up to 3 months. Thaw overnight in the refrigerator and reheat gently with a splash of broth.
Reheating: Reheat on the stovetop over medium-low heat or in the microwave in 1-minute intervals, stirring in between.
Food safety: Refrigerate within 2 hours of cooking. Reheat leftovers until hot throughout — 165°F.
Frequently Asked Questions
What’s the best cut of beef for crockpot pepper steak?
Chuck roast or stew meat. Chuck has the marbling and connective tissue to become fork-tender during a long cook. Sirloin, round, and loin are too lean and will dry out.
How long do you cook pepper steak in a crockpot?
6–8 hours on LOW or 3–4 hours on HIGH. The beef is done when it’s fork-tender.
Can I put frozen beef in the crockpot?
It’s not recommended for food safety reasons. Frozen beef takes too long to reach a safe internal temperature. Thaw it in the refrigerator first.
Why is my pepper steak sauce thin?
You probably skipped the cornstarch slurry or added it too early. Stir in 2 tbsp cornstarch mixed with 2 tbsp cold water during the last 10 minutes of cooking.
Can I add the peppers at the beginning?
You can, but they’ll turn soft and lose their color. Adding the peppers in two stages keeps them crisp and bright.
Can I make this in an Instant Pot?
Yes. Brown the beef on sauté mode, add the broth, soy sauce, brown sugar, rice vinegar, garlic, ginger, and two-thirds of the peppers. Cook on high pressure for 20 minutes, then let it release naturally for 10 minutes. Add the remaining peppers and the cornstarch slurry, then sauté for 3–5 minutes until thickened.
Is this recipe gluten-free?
Use tamari or gluten-free soy sauce and confirm your beef broth is gluten-free. Everything else is naturally gluten-free.
Can I double the recipe?
Yes. Use a 6-quart or larger slow cooker. Cooking time stays roughly the same, but you may need to leave the lid off for 15–20 minutes at the end to reduce the extra liquid.
Can I use ground beef instead of chuck roast?
Yes. Brown 1½ lbs of lean ground beef first, then add everything to the slow cooker and cook on LOW for 3–4 hours. It’s faster and cheaper.
What do I serve with crockpot pepper steak?
Serve with jasmine rice, white rice, brown rice, cauliflower rice, or lo mein noodles. Steamed broccoli or green beans on the side make it a complete meal.
