🥩 Pepper Steak in a Crock Pot – A Flavor-Packed Slow Cooker Classic

 

This dish comes together with pantry staples and fresh ingredients, turning simple sirloin and vegetables into a savory and satisfying meal.

Ingredients

  • 2 pounds beef sirloin, cut into 2-inch strips

  • ¾ teaspoon garlic powder, or to taste

  • 3 tablespoons vegetable oil

  • 1 cube beef bouillon

  • ¼ cup hot water

  • 1 tablespoon cornstarch

  • ½ cup chopped onion

  • 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

📝 Tip: You can substitute the green peppers with red or yellow for a sweeter flavor and more color variety.

Instructions

Step 1: Season and Sear the Beef

Sprinkle the beef sirloin strips with garlic powder.

Heat 3 tablespoons of vegetable oil in a large skillet over medium heat. Add the beef strips and sear for about 5 minutes per side, or until browned. This locks in flavor and adds a beautiful golden crust.

🔥 Pro Tip: Don’t overcrowd the pan—sear in batches if needed for better browning.

Once browned, transfer the beef to the bottom of your slow cooker.

Step 2: Make the Flavor Base

In a small bowl or measuring cup:

  • Dissolve 1 beef bouillon cube in ¼ cup hot water.

  • Stir in 1 tablespoon cornstarch until fully dissolved.

This creates a thickening base for the rich sauce that forms in the slow cooker.

Step 3: Layer the Ingredients

Pour the bouillon-cornstarch mixture into the crock pot over the beef.

Add the remaining ingredients:

  • ½ cup chopped onion

  • 2 large chopped green bell peppers

  • 1 (14.5 oz) can stewed tomatoes, with liquid

  • 3 tablespoons soy sauce

  • 1 teaspoon white sugar

  • 1 teaspoon salt

Stir gently to combine everything in the crock pot.

Step 4: Slow Cook to Perfection

Cover the slow cooker and set it to:

  • HIGH for 3–4 hours

  • LOW for 6–8 hours

🍽️ Cooking Tip: The longer it cooks on low, the more tender and flavorful the beef becomes. It will soak up the savory sauce and become fork-tender.
