Restaurant pepper steak is usually a fast dinner: beef hits a hot wok, peppers stay crisp-tender, and a savory sauce comes together in minutes.
This crockpot pepper steak takes a slower route. The beef cooks gently in a flavorful ginger-soy sauce until tender, while the peppers are added in stages so you get a mix of deeply softened and fresher, slightly crisp pieces.
This easy pepper steak crockpot dinner feels comforting without requiring much hands-on cooking. Serve it over rice or noodles for a simple weeknight meal the whole family can dig into.
Why This Crockpot Pepper Steak Works
A few small techniques make a big difference.
- Chuck steak provides reliable tenderness. It has enough connective tissue to benefit from slow cooking without requiring an unusually long cook.
- Add the peppers at different times. Some cook with the beef for a softer texture, while the rest are added near the end so they retain more bite.
- The sauce thickens at the end. A simple cornstarch slurry gives the sauce a glossy consistency that clings to the beef and vegetables.
- Ginger, garlic, soy sauce, and sesame oil build depth. Brown sugar balances the salty soy sauce, while rice vinegar adds brightness.
- Searing is optional. Browning the beef first adds another layer of flavor, but the crockpot can cook it without.
- It works well for meal prep. The beef and sauce hold up nicely in the refrigerator and freezer.
The biggest change from many Crockpot pepper steak recipes is that this recipe doesn’t treat every cut of beef as interchangeable. Chuck steak is the primary recommendation because it gives you a more predictable result.
Crockpot Pepper Steak Recipe
This easy crockpot pepper steak recipe turns tender beef, sweet peppers, and onions into a rich ginger-soy dinner. Serve it over rice for an easy meal.
Ingredients
For the Beef and Vegetables
- 2 pounds boneless chuck steak or chuck roast, trimmed and sliced into thin strips
- 2 tablespoons neutral cooking oil, divided
- 1 medium yellow onion, sliced
- 3 bell peppers, preferably a mix of green, red, and yellow, sliced
- 4 garlic cloves, minced
- 1 tablespoon freshly grated ginger
- ½ teaspoon black pepper
- ¼ teaspoon red pepper flakes, optional
For the Sauce
- 1 cup low-sodium beef broth
- ¼ cup low-sodium soy sauce
- 1 tablespoon rice vinegar
- 1½ tablespoons brown sugar
- 1 teaspoon tomato paste
- 1 teaspoon toasted sesame oil
For Thickening
- 1 tablespoon cornstarch
- 2 tablespoons cold water
For Serving
- Cooked white or brown rice
- Cooked noodles, optional
- Sliced green onions
- Sesame seeds, optional
Instructions
- Slice the Beef Properly.
Trim tough fat and slice the chuck steak into thin ¼-inch strips against the grain (put the meat in the freezer for 20–30 minutes beforehand if it is hard to cut), skipping a cornstarch coating since a final slurry provides better sauce control. - Optional: Sear the Beef.
Sear the beef in batches in 1 tablespoon of hot oil over medium-high heat for 1–2 minutes per side just to brown the edges (transferring to the slow cooker afterward), or skip this step entirely if short on time. - Build the Crockpot.
Add the sliced onion, about two-thirds of the bell peppers, garlic, ginger, and black pepper to the slow cooker over the beef, pour over a whisked mixture of beef broth, soy sauce, rice vinegar, brown sugar, tomato paste, and red pepper flakes, and cook on LOW for 4–5 hours until tender. - Add the Remaining Peppers.
Stir in the remaining bell peppers 20–30 minutes before serving to keep them vibrant and crisp-tender. - Thicken the Sauce.
Whisk together 1 tablespoon cornstarch and 2 tablespoons cold water into a slurry, stir it into the crockpot, and cook uncovered on HIGH for 15–20 minutes, stirring occasionally until glossy and thick (adding a splash of broth if it becomes too thick). - Finish and Serve.
Turn off the slow cooker, stir in the sesame oil, taste before adding extra salt, and serve over hot rice or noodles garnished with green onions and sesame seeds.

Choosing the Best Beef for Pepper Steak
The first article’s broad list of flank, round, chuck, skirt, minute steak, and even ground beef makes the recipe flexible, but those cuts don’t behave the same way during slow cooking.
For this recipe, chuck steak or chuck roast is the most predictable choice.
Chuck Steak or Chuck Roast
Best choice for this slow cooker version. The beef becomes tender as it cooks gently in the sauce.
Round Steak
A leaner alternative. It can work, but it is less forgiving than chuck and may not become as succulent.
Flank Steak
Excellent for traditional quick-cooking pepper steak, but it doesn’t need the same long, slow-cooking treatment as chuck.
Skirt Steak
Flavorful but better suited to quick, high-heat cooking.
Minute Steak
Very thin and fast-cooking, making it a poor match for a long crockpot cook.
Ground Beef
Ground beef can certainly be turned into a pepper-and-onion skillet or slow cooker meal, but it is a different dish rather than a direct substitute for sliced beef pepper steak.
If you want a dependable crockpot pepper steak recipe, keeping the main recipe focused on chuck makes the instructions much easier to trust.
Tips for the Best Crockpot Pepper Steak
Slice Against the Grain
Look for the long muscle fibers running through the beef and cut across them, not parallel to them. Thin, even slices are especially important.
Don’t Crowd the Pan When Searing
If you sear the beef, work in batches. A crowded skillet traps moisture and prevents good browning.
Don’t Skip the Pepper Timing
Adding all the peppers at the beginning makes the vegetables very soft. Adding some near the end gives the finished dish more contrast.
Use Low-Sodium Soy Sauce
The broth and soy sauce both contribute salt. Starting with low-sodium versions gives you more control.
Don’t Add the Cornstarch Too Early
Cornstarch is most useful at the end, when you know exactly how much liquid you need to thicken.
Taste Before Serving
Depending on your soy sauce, broth, and peppers, you may need to adjust the sauce.
- Too salty? Add a splash of broth or water.
- Too sweet? Add a small splash of rice vinegar.
- Too flat? Add a little more soy sauce or vinegar.
- Too thin? Add another small cornstarch slurry.
- Not spicy enough? Add more red pepper flakes.
Easy Variations
Pepper Steak With Tomatoes
For a more old-fashioned pepper steak recipe crockpot with tomatoes, add one 14½-ounce can of diced tomatoes, drained slightly.
The tomatoes will make the sauce more savory and stew-like.
Green Pepper Crockpot Recipe
Prefer classic green peppers? Use three green bell peppers instead of a mixture of colors.
This makes a straightforward green pepper steak recipe with a slightly more savory, less sweet pepper flavor.
Pepper Steak With Mushrooms
Add 8 ounces of sliced mushrooms during the last 30–45 minutes of cooking. They add another savory layer without changing the basic sauce.
Pepper Steak With Water Chestnuts
For more crunch, add drained sliced water chestnuts during the final 15–20 minutes. This works particularly well if you want an All Recipes-style version with extra vegetables and texture.
Spicy Crockpot Pepper Steak
Increase the red pepper flakes or add a small amount of your favorite chili sauce.
Pepper Steak Noodles
Serve the finished beef and sauce over cooked rice noodles, egg noodles, or another sturdy noodle instead of rice.
Gluten-Free Pepper Steak
Use gluten-free tamari or certified gluten-free soy sauce. Check every packaged ingredient if you are cooking for someone with celiac disease or a strict gluten-free diet.
Can You Make Pepper Steak in the Oven?
Yes. If you don’t have a slow cooker, use a Dutch oven.
Brown the beef in batches, add the onion and sauce ingredients, cover, and cook at about 300°F until the beef is tender. Add the peppers in stages so they do not become completely soft.
Exact oven cooking time depends on the beef cut and thickness, so use tenderness as your guide.
Crockpot Pepper Steak Meal Prep
This slow cooker pepper steak is great for meal prep because the beef and sauce become even more flavorful after resting overnight.
Let the finished pepper steak cool promptly, then refrigerate it in airtight containers.
For the best texture:
- Store the beef and sauce with the peppers.
- Keep rice or noodles in a separate container if possible.
- Refrigerate for up to 4 days.
- Reheat gently in the microwave or on the stovetop.
- Add a splash of broth if the sauce has thickened too much.
To freeze, cool the pepper steak completely, then freeze it in airtight freezer containers for up to 3 months. Thaw overnight in the refrigerator and reheat gently.
What to Serve With Pepper Steak
The easiest pairing is steamed white rice because it soaks up the sauce.
You can also serve this beef pepper steak recipe with:
- Brown rice
- Jasmine rice
- Cauliflower rice
- Rice noodles
- Egg noodles
- Steamed broccoli
- Edamame
- Simple cucumber salad
For a more complete hot dinner, add a simple vegetable on the side rather than loading the crockpot with too many extra ingredients.
Frequently Asked Questions
What is the best cut of beef for crockpot pepper steak?
Chuck steak or chuck roast is the most dependable choice for this slow cooker recipe. Round steak can also work, but it is leaner and less forgiving.
Do I have to sear the beef first?
No. Searing adds browned flavor, but it is optional. If you want a true dump-and-go easy crock pot pepper steak, you can skip it.
Why is my pepper steak tough?
The most common reasons are using a cut that doesn’t suit the cooking method, cutting the beef too thick, or stopping before the beef becomes tender. Chuck needs enough time for its connective tissue to soften.
Can I use round steak?
Yes, but expect a somewhat leaner result. If you use round steak, watch for tenderness rather than automatically following the same cooking time.
Can I use frozen beef?
For the most predictable cooking and food-safety results, thaw the beef in the refrigerator before preparing the recipe. Avoid putting a large block of frozen beef directly into the slow cooker.
When should I add the peppers?
Add about two-thirds at the beginning and the remaining peppers during the final 20–30 minutes. This gives you both tender and slightly crisp-tender peppers.
Can I make this crockpot pepper steak without cornstarch?
Yes, but the sauce will be thinner. You can simmer it uncovered to reduce it, although the cornstarch slurry is faster and gives the sauce a more classic glossy texture.
Can I make this recipe gluten-free?
Yes. Use gluten-free tamari or certified gluten-free soy sauce and check the labels of your broth and other packaged ingredients.
Can I make pepper steak in an Instant Pot?
Yes, but you’ll need to change the cooking method because an Instant Pot cooks under pressure rather than slowly. Use a tested pressure-cooker method rather than simply converting the slow-cooker timing.
Is this the same as Chicago pepper steak?
Not exactly. Chicago beef and Chicago Italian beef are different preparations, generally centered on Italian-seasoned roast beef and its cooking juices. This recipe is a soy-ginger pepper steak with bell peppers and onions.
Can I use this as a crock pot green pepper recipe?
Yes. Use green bell peppers in place of the mixed peppers. The result is a classic green pepper crockpot recipe variation.
The Bottom Line
This crockpot pepper steak keeps the best parts of classic pepper steak—tender beef, colorful peppers, onions, and a savory sauce—while making the cooking much more hands-off.
The key is not trying to make every cut of beef behave the same way.
Chuck gives the slow cooker enough time to turn a relatively inexpensive cut into tender, flavorful beef. Adding the peppers in two stages keeps the finished dish from becoming one-note and soft.
Serve over rice, spoon plenty of sauce on top, and finish with green onions and sesame seeds for an easy beef sandwich. No—keep this one firmly in the rice-bowl category where the sauce can shine.
For another variation, try the tomato-based version or swap the rice for noodles.
