How To Make Pepper Steak In The Crock Pot
Prepare the beef: Thinly slice the steak against the grain into strips using a sharp knife.
Add beef and vegetables: Prepare the peppers and onions and add them to the crock pot along with the sliced beef.
Mix together the sauce: In a small bowl, whisk together the sauce ingredients until they are fully combined and no lumps remain. Pour the sauce over the meat and vegetables.
Slowly cook: Add the lid to the top and cook on HIGH for 3-4 hours or on LOW for 6-7 hours. Or until the steak is fork tender.
Serve: Ladle the beef and vegetables over a bed of rice, noodles, veggies, or your favorite grains. Enjoy!
Recipe Tips
- If you need help cutting the beef into small strips, place it in the freezer for about 20 minutes prior to cutting. This will firm up the meat and make it easier to thinly slice.
- The sauce can be made ahead of time and stored in the fridge until you're ready to use it.
- If you don't have time to make the sauce from scratch, you can also use a jar of pre-made pepper steak sauce. Just add it to the crock pot along with the beef and vegetables.
- You can add the peppers in the last hour of cooking to ensure they don't get too mushy.
- If you don't have fresh on hand, use dried ginger and garlic instead.
Variations
- Use different cuts of beef: Other cuts of beef that work well in this recipe include flank steak, skirt steak, or round steak.
- Try different proteins: If you're not a fan of beef, you can also use chicken, pork, or lamb in this recipe. Just be sure to adjust the cook time accordingly.
- Try different vegetables: Add in some chopped carrots, broccoli, mushrooms, or zucchini in the last hour of cooking for more nutrients an fiber.
- Make it spicier: Add in more crushed red pepper flakes to the sauce or serve with sriracha on the side.
- Make it gluten-free: Use Tamari or coconut aminos in place of the soy sauce. Be sure to use a gluten-free beef broth as well.
- Serve low carb: Instead of rice, use cauliflower rice or serve the steak and vegetables over a bed of steamed broccoli or zucchini noodles.
Storing & Freezing
Storing: Once cooled, any leftovers can be stored in an airtight container and kept in the fridge for up to 4 days.
Freezing: To freeze, add the cooled steak and vegetables to a freezer-safe bag or container. Store in the freezer for up to 3 months. When ready to eat, thaw overnight in the fridge then reheat on the stove over medium heat until warmed through.
