How to Make Slow Cooker Pepper Steak

Making this delicious slow cooker pepper steak is surprisingly simple, and the results are incredibly rewarding. You’ll be amazed at how tender the beef gets with just a few hours in the slow cooker. This crock pot pepper steak recipe is perfect for those nights when you want a hearty meal without a lot of fuss.

Step 1: If you’re opting to brown the beef for extra flavor, heat 1 tbsp olive oil in a large skillet over medium-high heat. Sear the thinly sliced steak strips for about 1–2 minutes per side until nicely browned. Don’t overcrowd the pan; work in batches if needed. This step isn’t essential but really deepens the flavor profile of your beef and pepper slow cooker dish.
Step 2: Add the prepared beef strips, sliced bell peppers (red and green), sliced onion, and minced garlic directly into your slow cooker. Arrange them evenly to ensure everything cooks consistently.
Step 3: In a separate bowl, whisk together the 1 cup beef broth, 1/4 cup low-sodium soy sauce, 2 tbsp brown sugar, 1 tsp ground ginger, and 1/2 tsp black pepper. This is the foundation of that irresistible savory sauce that makes this crock pot pepper steak recipe a favorite.
Step 4: Pour the whisked sauce mixture evenly over the ingredients in the slow cooker. Make sure to scrape all the flavorful bits from the bowl into the cooker.
Step 5: Cover the slow cooker and cook on the low setting for 6–7 hours or on the high setting for 3–4 hours. You’ll know it’s ready when the beef is fork-tender and the vegetables are soft. The aroma filling your kitchen will be amazing!
Step 6: About 30 minutes before serving, prepare the cornstarch slurry. In a small bowl, mix 1 tbsp cornstarch with 2 tbsp water until smooth. Stir this mixture into the slow cooker. Continue to cook, uncovered, until the sauce has thickened to your desired consistency. This final step ensures a rich, glossy sauce for your crock pot beef and peppers.
Step 7: Stir gently to combine the thickened sauce. Serve your delicious slow cooker pepper steak immediately.

Browning the Beef

While not strictly necessary, browning the beef strips before adding them to the slow cooker adds a wonderful depth of flavor. Searing the meat creates a richer, more complex taste in the final dish, making this best slow cooker pepper steak even more satisfying.

Slow Cooking and Thickening

Let your slow cooker work its magic on low for 6-7 hours or high for 3-4 hours. In the last 30 minutes, a simple cornstarch and water slurry is stirred in to create that perfect, luscious sauce consistency for your crock pot pepper steak recipe.

How do I make the sauce thicker if it’s too thin?

If your sauce isn’t as thick as you’d like after the cornstarch slurry, you can easily fix it.

Can I add other vegetables to my slow cooker pepper steak?

Variations of Slow Cooker Pepper Steak You Can Try

While the classic version of this slow cooker pepper steak is fantastic, don’t be afraid to experiment! There are so many ways to adapt this recipe to suit your tastes and dietary needs. Here are a few ideas to get you started:

Low Carb Delight: For a low carb slow cooker pepper steak, skip the brown sugar and use a sugar substitute like erythritol or stevia. Serve it over cauliflower rice or zucchini noodles instead of traditional rice to keep the carbs down. It’s a satisfying way to enjoy the flavors without the extra carbohydrates.
Spicy Sensation: Love a little heat? Amp up the red pepper flakes, add a chopped jalapeño or serrano pepper along with the onions and peppers, or even stir in a swirl of sriracha at the end. This adds an exciting kick to your crock pot beef and peppers.
Mushroom Medley: Sliced mushrooms are a wonderful addition! Add about 8 ounces of sliced cremini or white mushrooms along with the onions and peppers. They absorb the sauce beautifully and add an extra layer of earthy flavor to your slow cooker Chinese pepper steak.
Vegetarian Twist: While less common, you can create a delicious vegetarian slow cooker pepper steak by substituting the beef with firm tofu, seitan, or a hearty mix of mushrooms and other vegetables like broccoli and carrots. Adjust the cooking time as needed for these substitutes.
