Looking for a super easy meal that everyone will love? This pepper steak is great for busy weeknights but elegant enough for Sunday dinner! It features a rich and flavorful sauce, perfectly crisp peppers, and juicy sirloin steak for a satisfying and filling meal.

Why This Recipe Works

Thanks to the slow cooker, you can easily prep this pepper steak in the morning and let it cook all day! That way it's ready by dinnertime and all you have to do is give it a stir and serve it up.

I love to use a medley of sweet bell peppers for pops of fun color, and top sirloin steak gets perfectly tender and soaks up all the flavor of the savory sauce.

Ingredients Needed

Labeled ingredients for slow cooker pepper steak.

Beef Stock: You can also use chicken broth or vegetable broth, but beef broth works well with the steak.
Soy Sauce
Beef Bouillon Cube: Infuses the dish with lots of savory beef flavor.
Worcestershire Sauce
Brown Sugar: Helps balance out the rich savory sauce with a little bit of complex sweetness.
Ground Ginger
Salt and Black Pepper
Cornstarch: Thickens up the sauce and prevents it from getting too watery or thin.
Top Sirloin: You can use another kind of steak if you prefer, but top sirloin is my favorite choice for this recipe.
Bell Peppers: I use a combination of yellow bell pepper, red bell pepper, and green bell peppers, but you can use just green peppers if you like.
White Onion
Garlic

Recipe Tips

Be sure not to cut the peppers too small or they might get mushy as they slow cooker.
Garnish with some sesame seeds or a sprinkle of chopped green onions.
Instead of sirloin, you can use flank steak, skirt steak, round steak, or chuck roast. Another option is to pick up some beef stew meat, which will already be cut into the perfect sized chunks.
For leftovers, allow everything to cool and transfer to an airtight container. Your leftovers should last for 3 to 4 days in the fridge and they're perfect for meal prep! You can also freeze your pepper steak for a month or so.
To reheat, microwave your steak for about a minute and give it a stir, and then continue to microwave in 30 second increments until it's heated through. From frozen, allow it to thaw first.

Recipe FAQ's

Why is Chinese pepper steak so tender?

A typical Chinese pepper steak recipe involves a cooking process where the steak is coated in corn starch, egg white, and seasonings and then cooked in hot oil. This helps retain the moisture while adding lots of flavor.

Can you put raw steak in a slow cooker?

Absolutely! As long as you cook it fully, it's perfectly safe to slow-cook raw meat. Steak is safe to eat when it reaches a minimum of 145 degrees F.
