Ingredients

Here’s everything you’ll need to make this delicious slow cooker pepper steak:

2 pounds beef sirloin, cut into 2-inch strips
¾ teaspoon garlic powder
3 tablespoons vegetable oil
1 beef bouillon cube
¼ cup hot water
1 tablespoon cornstarch
½ cup onion, chopped
2 large green bell peppers, sliced
1 (14.5-ounce) can stewed tomatoes, with liquid
3 tablespoons soy sauce
1 teaspoon white sugar
1 teaspoon salt

Step-by-Step Instructions

1. Season and Sear the Beef

Sprinkle beef sirloin strips with garlic powder. Heat vegetable oil in a large skillet over medium heat and sear the beef for about 5 minutes on each side, until nicely browned. This adds depth of flavor. Transfer the beef to your slow cooker.

2. Prepare the Sauce

In a small bowl, dissolve the beef bouillon cube in ¼ cup hot water. Stir in the cornstarch until smooth. This will thicken the sauce as it cooks.

3. Combine Ingredients

Pour the bouillon-cornstarch mixture over the beef in the slow cooker. Add onion, green bell peppers, stewed tomatoes, soy sauce, sugar, and salt. Stir gently to mix.

4. Slow Cook

Cover and cook on:

High for 3–4 hours OR
Low for 6–8 hours

The longer it cooks, the more tender the beef will become.

Expert Tips & Variations

For Extra Flavor: Add a splash of Worcestershire sauce or a pinch of red pepper flakes for a subtle kick.
Veggie Variations: Swap green peppers for red or yellow bell peppers for extra sweetness and color.
Make It Low-Sodium: Use reduced-sodium soy sauce and skip the added salt.
Serving Ideas: Best served over steamed rice, egg noodles, or even mashed potatoes for a heartier dish.

Important Notes

Always sear the beef before adding it to the slow cooker. This step locks in flavor and prevents the meat from becoming bland.
Don’t lift the slow cooker lid too often—it releases heat and increases cooking time.
The cornstarch mixture should be stirred well to avoid lumps in the sauce.

Frequently Asked Questions

Q1: Can I use a different cut of beef?
Yes! Flank steak, round steak, or chuck roast work well. Just slice into strips before cooking.

Q2: Can I make this ahead of time?
Absolutely. Store in an airtight container in the fridge for up to 4 days or freeze for up to 3 months.

Q3: My sauce came out too thin. How can I thicken it?
Mix 1 tablespoon cornstarch with 2 tablespoons cold water and stir it in during the last 30 minutes of cooking.

Q4: Can I add other vegetables?
Yes! Mushrooms, snap peas, or even broccoli can be added in the last hour of cooking for more texture and flavor.

Q5: Do I have to use a slow cooker?
No. You can make this on the stovetop by simmering everything on low heat for 1.5 to 2 hours, stirring occasionally.
