There’s something magical about walking into your home after a long day and being greeted by the mouthwatering aroma of a meal that’s been slowly cooking to perfection. That’s exactly the experience you’ll have with this incredible Crock Pot Pepper Steak recipe. As someone who has been preparing slow-cooker meals for over a decade, I can confidently say that this dish has earned its place as a family favorite in countless homes, including mine.
Pepper steak is a classic dish that combines tender strips of beef with colorful bell peppers in a savory sauce. When prepared in a slow cooker, the flavors have hours to meld together, creating a depth that simply can’t be achieved with quicker cooking methods. The beef becomes incredibly tender, absorbing all the rich flavors of the sauce, while the peppers maintain just enough bite to provide a satisfying texture contrast.
What I love most about this recipe is its versatility. You can adjust the spice level to suit your taste preferences, swap out different colored bell peppers for visual appeal, or even add other vegetables that need using up in your refrigerator. It’s economical too – using less expensive cuts of beef that become wonderfully tender through the slow cooking process.
So let’s dive into creating this delicious Crock Pot Pepper Steak that will soon become a staple in your meal rotation!
Ingredients You’ll Need
For this Crock Pot Pepper Steak recipe, I’ve carefully selected ingredients that work together to create a harmonious blend of flavors while keeping the preparation straightforward. Here’s everything you’ll need:
For the Beef and Vegetables:
- 2 pounds beef sirloin or round steak, sliced into thin strips
- 3 bell peppers (preferably a mix of red, green, and yellow for color)
- 1 large onion
- 2 cloves garlic, minced
- 1 tablespoon fresh ginger, grated (or 1 teaspoon ground ginger)
- 2 cups beef broth (low sodium recommended)
- 1/4 cup soy sauce (low sodium)
- 2 tablespoons cornstarch
- 1/4 cup cold water (for cornstarch slurry)
- 2 tablespoons vegetable oil
- 1 can (14.5 oz) diced tomatoes, drained
- 1 tablespoon brown sugar
- 1 teaspoon black pepper
- 1/2 teaspoon red pepper flakes (adjust to taste)
For Serving:
- 4 cups cooked rice (white or brown)
- Sliced green onions for garnish
- Sesame seeds for garnish (optional)
I always recommend using fresh ingredients whenever possible, especially for the bell peppers as they’re a star component of this dish. The combination of different colored peppers not only adds visual appeal but also provides slightly different flavor profiles – green peppers are slightly more bitter, while red and yellow are progressively sweeter.
Essential Equipment
Having the right tools makes preparing this dish much easier. Here’s what you’ll need:
- 6-quart slow cooker/Crock Pot (larger is fine too)
- Sharp chef’s knife for slicing beef and vegetables
- Cutting board
- Large skillet for browning the beef (optional but recommended)
- Measuring cups and spoons
- Small bowl for mixing cornstarch slurry
- Wooden spoon or spatula
- Rice cooker or pot for cooking rice
Preparation Steps
I’ve broken down the preparation process into clear, manageable steps so you can create this delicious meal with confidence:
Step 1: Prepare the Beef
- If your beef isn’t pre-sliced, place it in the freezer for about 20-30 minutes before cutting. This firms it up slightly, making it easier to slice thinly.
- Slice the beef against the grain into thin strips, approximately 1/4 inch thick and 2-3 inches long.
- Season the beef strips with salt and black pepper.
- Heat 1 tablespoon of vegetable oil in a large skillet over medium-high heat.
- Working in batches to avoid overcrowding (which prevents proper browning), sear the beef strips for about 1-2 minutes per side until they develop a nice brown crust.
- Transfer the browned beef to your slow cooker.
Note: While browning the beef is technically optional, I strongly recommend not skipping this step. Browning creates the Maillard reaction, which adds tremendous depth of flavor to the final dish.
Step 2: Prepare the Vegetables
- Wash the bell peppers, remove the seeds and white membranes, then slice into strips about 1/4 inch thick.
- Peel the onion and slice into similar-sized strips.
- Mince the garlic and grate the fresh ginger (if using).
- Add the remaining tablespoon of oil to the same skillet you used for the beef.
- Sauté the onions for about 2 minutes until they begin to soften.
- Add the garlic and ginger, cooking for another 30 seconds until fragrant.
- Transfer the onion mixture to the slow cooker with the beef.
I prefer to add the bell peppers later in the cooking process to prevent them from becoming too soft, but if you’re pressed for time in the morning, you can add them now.
Step 3: Prepare the Sauce and Start Cooking
- In a bowl or measuring cup, whisk together the beef broth, soy sauce, and brown sugar.
- Pour this mixture over the beef and onions in the slow cooker.
- Add the drained diced tomatoes and red pepper flakes.
- Cover and cook on LOW for 6-7 hours or on HIGH for 3-4 hours.
Step 4: Add the Peppers
- When there are about 30-45 minutes of cooking time remaining, add the sliced bell peppers to the slow cooker.
- Stir gently to combine with the beef and sauce.
- Continue cooking for the remaining time.
Adding the peppers later in the cooking process ensures they retain some texture and don’t become mushy.
Step 5: Thicken the Sauce
- About 15 minutes before serving, mix the cornstarch with cold water in a small bowl until smooth.
- Remove the lid of the slow cooker and stir in the cornstarch slurry.
- Turn the slow cooker to HIGH if it isn’t already, and cook uncovered for 15 minutes, or until the sauce has thickened to your desired consistency.
- Taste and adjust seasoning if necessary.
Step 6: Serve and Enjoy
- Serve the pepper steak over hot cooked rice.
- Garnish with sliced green onions and sesame seeds if desired.

Tips for Perfect Crock Pot Pepper Steak
Over the years, I’ve discovered several techniques that elevate this dish from good to extraordinary. Here are my top tips:
Beef Selection and Preparation
- Choose the Right Cut: While sirloin or round steak are excellent choices, you could also use flank steak or chuck roast. The slow cooking process will tenderize tougher cuts beautifully.
- Slice Against the Grain: This is crucial for tender meat. Cutting against the grain shortens the muscle fibers, making the beef easier to chew.
- Uniform Slicing: Try to cut the beef strips to a similar thickness so they cook evenly.
Cooking Techniques
- Don’t Skip the Browning: Taking time to sear the meat before adding it to the slow cooker adds tremendous flavor through the Maillard reaction.
- Resist the Urge to Peek: Every time you lift the lid of your slow cooker, heat escapes, and you’ll need to add about 20 minutes to the cooking time.
- Temperature Control: If your slow cooker runs hot (some newer models do), consider using the LOW setting even if the recipe suggests HIGH.
- Layering Matters: Place harder vegetables like onions at the bottom of the pot, closer to the heat source.
Flavor Enhancements
- Fresh Herbs Finish: Add fresh herbs like cilantro or basil right before serving for a burst of fresh flavor.
- Acid Balance: A splash of rice vinegar or fresh lime juice added at the end brightens all the flavors.
- Umami Boost: Consider adding a tablespoon of Worcestershire sauce or a teaspoon of fish sauce to the broth mixture for deeper umami flavor.
Make-Ahead and Storage Options
This Crock Pot Pepper Steak is excellent for meal prep and actually tastes even better the next day as the flavors continue to develop. Here’s how to make the most of leftovers:
Preparation in Advance
- Meal Prep: You can slice all the beef and vegetables up to 24 hours in advance and store them separately in airtight containers in the refrigerator.
- Freezer Meal Preparation: Combine the raw beef, onions, garlic, ginger, broth, soy sauce, brown sugar, and tomatoes in a freezer-safe bag. Freeze for up to 3 months. Thaw in the refrigerator overnight before cooking. Add fresh bell peppers during cooking as directed.
Storage Guidelines
- Refrigeration: Store cooled leftovers in an airtight container in the refrigerator for up to 4 days.
- Freezing Cooked Pepper Steak: The cooked dish freezes well for up to 3 months. The peppers may be slightly softer when thawed, but the flavor remains excellent.
- Reheating: Reheat portions in the microwave for 2-3 minutes, stirring halfway through. Alternatively, reheat in a skillet over medium heat until warmed through.

Common Troubleshooting
Even experienced cooks occasionally encounter issues. Here are solutions to common problems when making Crock Pot Pepper Steak:
Meat is Tough
Problem: The beef hasn’t become tender even after the recommended cooking time. Solution: Continue cooking for another 30-60 minutes on LOW. Some cuts may need additional time depending on the size and quality of the meat. If you’re short on time, transfer everything to a covered pot and simmer gently on the stovetop until the meat tenderizes.
Sauce is Too Thin
Problem: The sauce hasn’t thickened properly. Solution: Mix an additional tablespoon of cornstarch with 2 tablespoons of cold water and add to the slow cooker. Increase heat to HIGH and cook uncovered for another 15 minutes, stirring occasionally.
Vegetables Are Too Soft
Problem: The bell peppers have become mushy. Solution: Next time, add them even later in the cooking process, perhaps only in the final 20 minutes. For the current batch, consider adding fresh raw bell pepper strips just before serving – the hot sauce will slightly soften them while maintaining some crunch.
Too Salty
Problem: The finished dish tastes too salty. Solution: Add a peeled, quartered potato to the slow cooker for the last 30 minutes of cooking (remove before serving) – it will absorb some of the salt. You can also serve with additional plain rice or add a tablespoon of unsalted butter to mellow the saltiness.
Questions and Answers
I’ve compiled some of the most frequently asked questions about making Crock Pot Pepper Steak:
Q: Can I put frozen beef directly in the slow cooker?
While technically possible, I don’t recommend it for safety reasons. Frozen meat takes too long to reach a safe temperature in a slow cooker, potentially allowing harmful bacteria to multiply. Always thaw meat completely in the refrigerator before adding it to your Crock Pot.
Q: My family doesn’t like bell peppers. What can I substitute?
You can replace bell peppers with snow peas, sugar snap peas, broccoli florets, or sliced zucchini. Add these vegetables during the last 30-45 minutes of cooking time to prevent them from becoming too soft.
Q: How spicy is this recipe?
As written with 1/2 teaspoon of red pepper flakes, this recipe has a mild to medium heat level. For a milder version, reduce or omit the red pepper flakes. To increase the spiciness, add more red pepper flakes or include 1-2 thinly sliced fresh jalapeños.
Q: Can I cook this on HIGH for the entire time?
Yes, you can cook this recipe on HIGH for 3-4 hours instead of LOW for 6-7 hours. However, I find that cooking on LOW produces more tender beef and allows the flavors to develop more fully. If using HIGH, be sure to check the meat tenderness earlier.
Q: Is there a way to make this recipe faster?
For a quicker version, you could use a pressure cooker or Instant Pot. Brown the beef using the sauté function, then pressure cook with the onions and sauce for 15 minutes with a natural pressure release. Add the bell peppers, switch back to sauté, and cook for an additional 5 minutes after thickening the sauce.
Q: How do I know when the beef is done?
The beef is done when it’s tender enough to easily pull apart with a fork. If it still seems tough or chewy, continue cooking for additional time.
Q: Can I double this recipe?
Yes, this recipe doubles well. Just ensure your slow cooker is large enough (at least 8 quarts) to accommodate the increased volume. The cooking time remains the same, but you may need additional time to properly brown all of the beef in batches before adding it to the slow cooker.
Final Thoughts
There’s something deeply satisfying about creating a meal that fills your home with mouthwatering aromas all day long. This Crock Pot Pepper Steak recipe delivers that experience along with a delicious, comforting meal that’s suitable for both weeknight dinners and special occasions.
What I love most about slow cooker recipes like this one is how they transform simple, affordable ingredients into something truly special.

I hope you enjoy this Crock Pot Pepper Steak as much as my family does. It’s one of those recipes that proves home cooking doesn’t have to be complicated to be deeply satisfying and impressive.
Q&A Section
Q: How can I make this recipe keto-friendly?
To make this recipe suitable for a ketogenic diet, skip the brown sugar or replace it with a keto-friendly sweetener like monk fruit or erythritol. Instead of cornstarch, use 1/2 teaspoon of xanthan gum to thicken the sauce. Serve over cauliflower rice instead of traditional rice for a low-carb meal that maintains all the delicious flavors of the original.
Q: Is it necessary to brown the beef first?
While you can technically skip the browning step and still have a tasty dish, I strongly recommend taking the extra time to sear the beef. Browning creates the Maillard reaction, which develops deep, complex flavors that really elevate the final dish. Think of it as building your flavor foundation – those few extra minutes of prep make a significant difference in the end result.
Q: Can this recipe be made in an Instant Pot instead of a slow cooker?
Absolutely! To adapt this for the Instant Pot, use the Sauté function to brown the beef in batches. Add the onions, garlic, and ginger and sauté briefly. Add the broth, soy sauce, brown sugar, and tomatoes. Seal and cook on High Pressure for 15 minutes with a 10-minute natural pressure release. Release remaining pressure, open the lid, add the bell peppers, and use the Sauté function for about 5 minutes. Thicken with cornstarch slurry as in the original recipe.
Q: How can I make this dish if I don’t have a slow cooker?
No slow cooker? No problem! You can make this on the stovetop or in the oven. For stovetop: Brown the beef in a Dutch oven or heavy-bottomed pot, then add the onions, garlic, ginger, and liquid ingredients. Simmer covered on low heat for about 1.5-2 hours until beef is tender. Add bell peppers for the last 20-30 minutes. For oven method: Follow the same steps but place the covered Dutch oven in a 325°F (165°C) oven for 2-2.5 hours, adding peppers for the last 30 minutes.
Q: What’s the best way to slice the beef thinly?
For the thinnest, most even slices, place your beef in the freezer for 20-30 minutes before cutting. This firms it up just enough to make slicing easier. Use a very sharp knife and cut against the grain in smooth, even strokes. Aim for slices about 1/4 inch thick. If you’re friendly with your butcher, you can also ask them to slice the beef for you – many are happy to accommodate this request.
