Begin by seasoning the beef sirloin strips with garlic powder, ensuring each piece is evenly coated. This simple seasoning adds a wonderful depth of flavor to the beef as it cooks.
Sear the Beef:
Heat the vegetable oil in a large skillet over medium heat. Once hot, add the beef strips and sear them for about 5 minutes on each side, or until they are browned. Searing the beef helps to lock in the juices and adds a rich, caramelized flavor to the dish. Once seared, transfer the beef strips to your slow cooker.
Prepare the Sauce:
In a separate container, dissolve the beef bouillon cube in ΒΌ cup of hot water. Once dissolved, stir in the cornstarch until fully combined. This mixture will thicken the sauce as it cooks. Pour the mixture into the slow cooker over the beef.
Add the Vegetables and Seasonings:
Next, add the chopped onion, green bell peppers, and stewed tomatoes (with their liquid) to the slow cooker. Stir in the soy sauce, sugar, and salt, mixing everything together to ensure the beef and vegetables are evenly coated with the flavorful sauce.
Cook the Pepper Steak:
Cover the slow cooker with its lid and set it to cook on High for 3 to 4 hours, or on Low for 6 to 8 hours. The longer cooking time on Low will yield the most tender results, as the beef slowly absorbs all the flavors, becoming melt-in-your-mouth delicious.
Serve and Enjoy:
Once cooked, give the pepper steak a final stir and serve it hot over a bed of steamed rice or alongside mashed potatoes for a complete meal. The combination of tender beef, soft bell peppers, and rich tomato sauce is sure to please everyone at the table.
