Equipment

  • Slow Cooker
  • Medium bowl
  • Small bowl

Ingredients
  

Main ingredients

  • 2 pounds beef sirloin cut into 2-inch strips
  • 0.75 teaspoon garlic powder or to taste
  • 3 tablespoons vegetable oil
  • 1 cube beef bouillon
  • 0.25 cup hot water
  • 1 tablespoon cornstarch
  • 0.5 cup onion chopped
  • 2 large green bell peppers roughly chopped
  • 1 (14.5 ounce) can stewed tomatoes with liquid
  • 3 tablespoons soy sauce
  • 1 teaspoon white sugar
  • 1 teaspoon salt

Instructions
 

  • In a medium bowl, toss your beef sirloin strips with the garlic powder and vegetable oil. Make sure each piece is nicely coated. This little step adds so much flavor right from the start!
  • In a small bowl, dissolve your beef bouillon cube in the hot water. Once it's all melty, whisk in the cornstarch until you have a smooth, lump-free mixture. This is what will give us that luscious sauce.
  • Now for the easy part! Place your coated beef strips directly into your slow cooker. Then, add in the chopped onion, chopped green bell peppers, and the entire can of stewed tomatoes (liquid and all!). Don't forget to drizzle in the soy sauce, sprinkle in the sugar, and add the salt.
  • Gently pour that cornstarch-bouillon mixture you made over everything in the slow cooker.
  • Cover your slow cooker and set it to cook. You have two options: cook on LOW for 6-8 hours for super tender, melt-in-your-mouth beef, or on HIGH for 3-4 hours if you're a bit more pressed for time. Either way, the result will be wonderfully tender beef swimming in a delicious, savory sauce.

Notes

This recipe is fantastic as is, but I love how adaptable it is! Feel free to add in other veggies like sliced carrots, mushrooms, or even a can of drained water chestnuts. If you like a little heat, add a pinch of red pepper flakes. A splash of Worcestershire sauce can add an extra layer of flavor. While sirloin is great, you could also try flank steak or even chuck roast (though chuck might need a bit longer to get tender).
Make sure your slow cooker isn't packed too tightly. You can chop all your veggies and measure out your ingredients the night before and store them in separate containers in the fridge. Then, it’s just a matter of dumping them in the morning!
Before serving, give your pepper steak a taste. Does it need a little more salt? A touch more soy sauce? Don't be afraid to adjust the seasonings to your preference.
If your sauce isn't as thick as you like after cooking, you can always make a little more cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) and stir it in during the last 30 minutes of cooking.
