Pepper Steak in a Crock Pot Ingredients
For the Beef
• Sirloin or Flank Steak – This cut becomes melt-in-your-mouth tender with slow cooking; trim excess fat for the best results.
For the Vegetables
• Bell Peppers – Their sweetness contrasts beautifully with the savory sauce; feel free to mix different colors for a vibrant dish.
• Onion – Adds depth and flavor; cutting it into chunks prevents them from dissolving during cooking.
For the Sauce
• Soy Sauce – Forms the rich, umami base of the dish; a gluten-free tamari or coconut aminos can be swapped for a gluten-free version.
• Beef Broth – Ensures moisture and enhances meat flavor; using low-sodium broth helps to control salt levels.
• Minced Garlic – Brightens the overall flavor profile; you can use garlic powder if you’re short on fresh garlic.
• Brown Sugar – Balances out the savory notes with a touch of sweetness; honey or maple syrup make great natural alternatives.
• Red Pepper Flakes – These bring a subtle heat, so adjust according to your spice tolerance; for more kick, try Sriracha instead.
• Cornstarch – Ideal for thickening the sauce later; arrowroot powder works just as well if preferred.

Step‑by‑Step Instructions for Pepper Steak in a Crock Pot
Step 1: Prepare the Beef
Begin by slicing your sirloin or flank steak into strips about 1-inch wide. Season the beef strips generously with salt and freshly ground black pepper to enhance flavor. This step is crucial as it sets the foundation for your Pepper Steak in a Crock Pot, ensuring every bite is deliciously seasoned.
Step 2: Prepare Vegetables
Next, take your vibrant bell peppers and onion, cutting them into large chunks (roughly 1-inch pieces). The colorful bell peppers not only add sweetness but also bring visual appeal to your dish. Arranging these veggies in the slow cooker makes for a beautiful presentation once your Pepper Steak is ready.
Step 3: Make Sauce
In a mixing bowl, whisk together the soy sauce, beef broth, minced garlic, brown sugar, and red pepper flakes. The combination of these ingredients creates a savory, umami-rich sauce that will coat your Pepper Steak beautifully. Feel free to adjust the heat by adding more or less red pepper flakes, depending on your preference.
Step 4: Layer Ingredients
Take your slow cooker and layer the sliced beef at the bottom. Then, gently place the prepared bell peppers and onion on top of the beef. Finally, pour the prepared sauce evenly over the layered ingredients, ensuring everything is well coated. This layering method helps infuse flavors throughout the cooking process.
Step 5: Cook
Cover the slow cooker with its lid and cook on low for 6-7 hours, or on high for 3-4 hours. The goal is to let the beef become tender and fully absorb the rich flavors of your Pepper Steak in a Crock Pot. A good visual cue is that the beef should shred easily with a fork when it’s done.
Step 6: Thicken Sauce
About 30 minutes before serving, mix cornstarch with cold water in a small bowl to create a slurry. Stir this slurry into the slow cooker, and then cover it again. This will thicken the sauce, giving your Pepper Steak a velvety texture that clings to the meat and vegetables beautifully.
Step 7: Serve and Enjoy
Once the cooking time is complete and the sauce has thickened, it’s time to serve your delicious Pepper Steak. Serve it over fluffy white rice, egg noodles, or alongside crusty bread to soak up the savory sauce. Enjoy the comforting flavors of this easy, delightful meal with family and friends!

Pepper Steak in a Crock Pot Recipe FAQs
How do I choose the best cut of beef for pepper steak?
Absolutely! I recommend opting for sirloin or flank steak as both cuts become wonderfully tender during the slow cooking process. Look for cuts that are bright red with minimal marbling for the best flavor. If you prefer a different texture or flavor, you can also use stew meat or round steak, but make sure to trim any excess fat for a leaner dish.
How should I store leftovers from my pepper steak?
Very simple! Store your delicious leftovers in an airtight container in the refrigerator for up to 3 days. This keeps your Pepper Steak fresh and ready for a cozy reheat anytime. Just remember to cool it down to room temperature before sealing to help retain its flavors.
Can I freeze pepper steak after cooking?
Definitely! For long-term storage, you can freeze portions of your Pepper Steak in airtight containers for up to 3 months. To do this, allow the dish to cool completely, then transfer it to freezer-safe containers, leaving a little space for expansion. When you’re ready to enjoy it, just thaw it in the refrigerator overnight before reheating.
What if my sauce doesn’t thicken properly?
If you find your sauce isn’t thickening as expected, don’t worry! Here’s a step-by-step remedy:
- In a small bowl, mix 2 tablespoons of cornstarch with 2 tablespoons of cold water to create a slurry.

- Cover and cook on high for an additional 30 minutes, checking to see if the sauce reaches your desired thickness. This will give you that lovely velvety texture you want!
Are there any dietary considerations for pepper steak?
