Crock Pot Pepper Steak Recipe Ingredients: Slow-Cooked Tender Beef and Peppers

This slow-cooker method delivers tender beef with peppers that practically melt in your mouth. The long cooking time transforms tough cuts into something extraordinary.

I’ve refined this technique to ensure the meat stays juicy while the peppers soften just enough. No fancy skills required—just let the crock pot do the work.

What you’ll get is a dish with deep, savory flavors and beef so tender it falls apart at the touch of a fork. The peppers absorb the rich sauce beautifully.

Perfect for busy weeknights when you want a hearty meal ready when you walk in the door. Here’s how to make it.

Ingredients for Crock Pot Pepper Steak Recipe Ingredients

Simple ingredients, big flavor. Beef, peppers, and a rich sauce come together effortlessly.

The beef is what makes this dish. Chuck or round steak works best—look for good marbling at Costco or your local butcher. Slice against the grain (ask them to do it if you’re unsure) for that melt-in-your-mouth texture. I grab my peppers at Trader Joe’s—they’re always crisp and fresh, and the colors make the dish pop (no sad, wilted ones).

No brown sugar? Honey or maple syrup at the same amount works in a pinch. Swap beef broth for mushroom broth if you want a vegetarian twist. The Worcestershire can be left out, but it adds a certain je ne sais quoi—Annie’s makes a great vegetarian version. For extra richness, add a splash of red wine to the sauce (whatever you’d drink).

This tastes even better the next day. Store in an airtight container in the fridge for up to 4 days, or freeze for 3 months. Reheat on the stove with a splash of water to thin the sauce (it thickens as it cools).

Step-by-Step Instructions for Crock Pot Pepper Steak

Here’s the method. Straightforward, tested, works every time.

Step 1: Sear the Beef Round Steak

Heat the 1 tbsp Olive Oil in a large skillet over medium-high heat. While it heats, pat the 1.5 lb Beef Round Steak dry with paper towels and season both sides with the 1 tsp Kosher Salt and 1 tsp Ground Black Pepper.

Add half the beef to the skillet, being careful not to overcrowd. Sear for 2-3 minutes per side until browned. Transfer to your slow cooker and repeat with the remaining beef. This step locks in flavor and ensures tender results.

Step 2: Layer the Vegetables and Start the Sauce

Slice the 2 whole Green Bell Pepper, 1 whole Red Bell Pepper, and 1 whole Yellow Onion as specified. Mince the 3 cloves Garlic Cloves. Arrange the sliced peppers and onion over the seared beef in the slow cooker.

In a bowl, whisk together the 0.5 cup Low-Sodium Soy Sauce, 2 tbsp Worcestershire Sauce, 2 tbsp Brown Sugar, and 2 tbsp Tomato Paste. Pour half of this mixture over the beef and vegetables. This creates the rich, savory base for your pepper steak.

Step 3: Slow Cook to Tender Perfection

Pour the 1 cup Beef Broth into the slow cooker, ensuring it covers the bottom. Cover and cook on low for 6-7 hours or high for 3-4 hours. The beef should become fork-tender and the flavors will meld beautifully.

Resist the urge to stir too often—this can break up the beef. Instead, check once halfway through cooking to ensure there’s enough liquid. The slow cooking process is what makes this dish so tender and flavorful.

Step 4: Thicken the Sauce and Finish

In a small bowl, mix the 2 tbsp Cornstarch with 2 tbsp of cold water to create a slurry. Stir this into the slow cooker during the last 30 minutes of cooking. This will thicken the sauce to the perfect consistency.

Taste and adjust seasoning if needed. The sauce should coat the back of a spoon and have a glossy appearance. The cornstarch slurry ensures your sauce isn’t too thin, giving you that classic pepper steak texture.

Serve hot over rice or noodles, making sure each serving gets plenty of the delicious sauce and tender beef.

Creative Variations of This Recipe

Asian Fusion Twist

Swap beef broth for coconut milk and add 1 tbsp ginger and 2 tbsp hoisin sauce to the sauce mixture. This creates a Thai-inspired version with creamy, slightly sweet undertones. I love serving this with jasmine rice for a complete meal. 🌟

Spicy Kick Option

Add 1 chopped jalapeño and ½ tsp red pepper flakes to the slow cooker with the peppers. This gives a subtle heat that builds gradually. If you want more fire, include 1 tbsp sriracha in the sauce mixture.

Mushroom Lovers

Add 8 oz sliced cremini mushrooms with the peppers and onions. They soak up the sauce beautifully and add a meaty texture. I find this variation particularly satisfying on cold evenings.

Vegetarian Version

Replace beef with 1.5 lb portobello mushrooms sliced into strips. Use mushroom broth instead of beef broth and add 1 tbsp liquid smoke to mimic that meaty depth. The texture is surprisingly similar to the original.

Honey Garlic Glaze

Replace brown sugar with 3 tbsp honey and add 2 extra minced garlic cloves. This creates a sticky, sweet-savory glaze that coats the beef and peppers beautifully. It’s become my go-to for impressing dinner guests. 💛

Pineapple Sweetness

Add 1 cup pineapple chunks during the last 30 minutes of cooking. The fruit absorbs the savory sauce while adding a bright contrast. This Hawaiian-inspired version pairs wonderfully with steamed rice.
