I love slow cooker recipes and this one was a big winner!  So easy to make and tasted great.  Serve it over rice or noodles.


  • 2 pounds beef sirloin, cut into 1/2×2 inch strips (1)
  • Garlic powder
  • 3 tablespoons vegetable oil
  • 1 cube beef bouillon
  • ¼ cup hot water
  • 1 tablespoon cornstarch
  • ½ cup chopped onion (1 medium onion)
  • 2 large green bell peppers, roughly chopped (about 2 cups) (2)
  • 1 (14.5 ounce) can stewed tomatoes, with liquid
  • 3 tablespoons soy sauce
  • 1 teaspoon white sugar
  • 1 teaspoon salt


Sprinkle beef with garlic powder.  In a large skillet over medium heat, heat the vegetable oil and brown the beef. (3) Transfer to a 4-quart slow cooker.

Mix bouillon cube with hot water until dissolved, then mix in cornstarch until dissolved.  Pour into the slow cooker.  Stir in onion, bell peppers (4), stewed tomatoes, soy sauce, sugar and salt.

Cover and cook on HIGH for 3 to 4 hours or LOW for 6 to 8 hours.


(1)     I used round steak.

(2)     Use any combination of peppers.  I used red and green.

(3)     I skipped this step and put the beef directly into the crock pot.

(4)     Wait until the last 45 minutes to add the peppers so they don’t get mushy.

  1. The pepper steak recipe I tried about 2 weeks ago was such a disaster and yours looks so good (mine looked NOTHING like your picture as I couldn’t even identify the peppers) that I just may have to be brave and try again using your recipe. I added the peppers in at the same time as the steak so I think reading this I now know where I may have gone wrong and why I ended up with “mush” instead of peppers in my pepper steak.

    1. My recipe actually said to add the peppers with the steak, too. But there was a note from the editors recommending that you add them during the last 45 minutes. I think that’s probably always going to be the case with peppers because it doesn’t take that long for them to cook – even in the slow cooker. This recipe really was easy and delicious!
