What Type of Meat is Pepper Steak?

Pepper steak isn’t a particular type of meat but refers to the fact that it’s beef cooked with bell peppers. For this recipe I typically prefer to use either top sirloin steak or round steak. You can also use flank steak if that’s what you have on hand or prefer.

How to Make Slow Cooker Pepper Steak:

This Chinese inspired pepper steak could not be any easier to make in the crockpot! It will take about 20 minutes including chopping your veggies. So simple and fast! Here’s a step by step, see the recipe card below for full directions.

  • First, you’ll whisk all of your sauce ingredients: broth, soy sauce, brown sugar, ginger, salt and pepper.
  • Then, add all of your meat, peppers, onions, garlic, tomatoes and mushrooms into the slow cooker.
  • Pour over your sauce, stir everything to combine and let it cook!
  • About 30-45 minutes before serving you can make your quick slurry of cornstarch and broth and let it get thick. Serve with your favorite rice.

Recipe & Ingredient Notes for Slow Cooker Pepper Steak:

  • You can use any color of bell peppers for this recipe, feel free to use whatever your taste preference is or what you have on hand.
  • We really love the tomatoes and mushrooms in this recipe, but they are optional! If you don’t like them just leave them out. You could also add some extra onion or an extra bell pepper instead if you wish.
  • NOTE ON COOK TIME: If cooking on LOW make sure you turn the heat up to HIGH and get the broth simmering before adding the cornstarch slurry. Stir it in and mix well, then allow to sit for 30 minutes or so till thick.
  • You can prep this with the sauce without cooking and freeze for up to 3 months. Then just dump in the crockpot and cook from frozen for 5-6 hours, or if thawed for 3-4.
