Easy Crockpot Pepper Steak – Tender & Flavorful

I remember a Tuesday when I was juggling work calls, school pickups, and a hungry family. The last thing I wanted was to hover over a stove. That's when I turned to my trusty crockpot and threw together this pepper steak with ingredients I already had. The result was so tender and flavorful that it became a weekly staple.

This crockpot pepper steak is like a slow dance of flavors: the beef gets meltingly tender, the peppers keep a slight crunch, and the sauce thickens into a glossy, savory coating. It's the set-it-and-forget-it dinner that delivers big on taste without the fuss.

I'll show you how to get the most out of your slow cooker, from choosing the right cut to avoiding a watery sauce. Let's get cooking.

About the Ingredients

1.5 lbs (680g) beef sirloin or chuck roast, sliced thin against the grain

Sirloin is leaner, chuck has more marbling for extra tenderness. For best results, partially freeze the beef for 20 minutes to make slicing easier.

2 tablespoons olive oil

Use a neutral oil with a high smoke point for searing. Avocado oil works too.

1/2 cup low-sodium soy sauce

Tamari or coconut aminos for a gluten-free option. Low-sodium prevents the dish from being too salty.

1/4 cup beef broth

Adds depth and helps create a rich sauce. You can substitute with water but broth is better.

1/4 cup brown sugar, packed

Balances the salty soy sauce and adds a subtle caramel note. Use coconut sugar for a less refined option.

2 tablespoons cornstarch

Thickens the sauce at the end. You can use arrowroot powder as a substitute.

3 cloves garlic, minced

Fresh garlic gives the best flavor; pre-minced is okay in a pinch.

1 teaspoon grated fresh ginger

Adds a warm, aromatic kick. Ground ginger (1/2 tsp) can substitute.

1/2 teaspoon red pepper flakes (optional)

For a little heat. Adjust to taste or omit for a milder version.

2 large bell peppers (1 red, 1 green), sliced into 1/2-inch strips

Use any colors you like. The red adds sweetness, green adds a bit of bitterness. You can also use a mix of mini peppers.

1 medium onion, sliced into thin wedges

Yellow or sweet onion works best. Slice thinly so it cooks evenly.

Cooked white rice, for serving

Jasmine or basmati are great. Cauliflower rice for a low-carb option.

Tips & Tricks

• Slice the beef against the grain for maximum tenderness. Cutting with the grain makes it chewy.
• Don't skip the searing step. Browning the beef develops a deep flavor that you can't get from just dumping it in the crockpot.
• Add the peppers and onions during the last 30 minutes of cooking to keep them crisp-tender, not mushy. If you prefer softer veggies, add them at the beginning.

Step-by-Step Instructions

1. Sear the beef

Heat olive oil in a large skillet over medium-high heat (350°F/175°C). Add beef slices in a single layer and sear for 2-3 minutes per side until browned but not cooked through. Work in batches to avoid steaming. Transfer to the crockpot.

2. Make the sauce

In a small bowl, whisk together soy sauce, beef broth, brown sugar, cornstarch, garlic, ginger, and red pepper flakes (if using) until smooth. Pour over the beef in the crockpot.

3. Add vegetables

Add the sliced bell peppers and onion on top of the beef. Do not stir yet – they will soften as they cook. Cover and cook on LOW for 6-7 hours or HIGH for 3-4 hours, until beef is fork-tender.

4. Thicken the sauce

If the sauce is thin, mix 1 tablespoon cornstarch with 2 tablespoons cold water in a small bowl. Stir into the crockpot. Cook on HIGH for 10-15 minutes, uncovered, until the sauce thickens and bubbles at the edges.

5. Season and serve

Taste and adjust seasoning with salt and pepper if needed (soy sauce is salty). Serve hot over steamed rice, spooning extra sauce over the top.

Delicious Variations

Add mushrooms

Sauté 8 oz sliced mushrooms with the onions and add them to the crockpot for extra earthy flavor.

Make it spicy

Add 1-2 sliced jalapeños or a splash of sriracha to the sauce for a kick.

Try a different protein

Use chicken breast or pork tenderloin, adjusting cooking time to 4-5 hours on low.
