This slow-cooker method transforms tough cuts of beef into tender, flavorful slices with minimal effort. The long, gentle cooking process allows the meat to become fork-tender while absorbing the rich savory sauce.
Bell peppers soften beautifully as they cook alongside the beef, creating a perfect balance of textures. The dish develops complex flavors as it simmers, with the peppers adding natural sweetness to the savory broth.
You’ll end up with melt-in-your-mouth beef strips coated in a glossy, slightly thickened sauce with soft peppers throughout. This is the kind of meal that tastes like it took all day to make, yet requires just minutes of prep.
Serve it over rice or noodles to soak up every drop of the delicious sauce. Here’s how to make this crowd-pleasing classic.

The beef is the star—flank steak or round steak works best here. Look for well-marbled cuts at Costco or your local butcher (they’ll often slice it thin for you if you ask). Pioneer Woman fans know she swears by Certified Angus Beef for these kinds of dishes. Don’t skip searing the beef first—it adds a depth of flavor that slow cooking alone can’t achieve.
No Worcestershire? Coconut aminos work as a decent substitute. Out of bell peppers? Frozen sliced peppers (thawed and drained) save the day. For a gluten-free version, swap soy sauce for tamari. The cornstarch can be replaced with arrowroot powder at a 1:1 ratio if needed. If you’re missing tomato paste, a tablespoon of ketchup in a pinch does the trick (just reduce sugar elsewhere).
This keeps beautifully for 4-5 days in the fridge. The flavors actually deepen overnight, so it’s perfect for meal prep. Freezes for up to 3 months—portion before freezing for easy reheating. Always store in airtight containers to prevent freezer burn.

Step-by-Step Instructions for Pepper Steak Recipe Crock Pot Pioneer Woman
This method guarantees fall-apart tender beef with vibrant peppers in a rich, savory sauce.
Step 1: Sear the Beef Round Steak
Heat the 1 tablespoon olive oil in a large skillet over medium-high heat. While it heats, pat the 1.5 lb beef round steak dry and season with the 1 teaspoon black pepper. Sear the slices in batches to avoid crowding the pan, cooking for 2-3 minutes per side until browned.
This searing step locks in juices and develops deep flavor. Don’t skip it—it’s the foundation of a rich sauce. Transfer the seared beef to your slow cooker as you work.
Step 2: Build the Sauce Base
In the same skillet, add the 1 whole yellow onion (thinly sliced) and cook for 3-4 minutes until softened. Stir in the 4 cloves garlic cloves (minced), 1 tablespoon ginger root (grated), and 2 tablespoons tomato paste, cooking for 1 minute until fragrant.
Deglaze the pan with the 0.5 cup soy sauce, 2 tablespoons Worcestershire sauce, and 1 cup beef broth, scraping up any browned bits. Pour this mixture over the beef in the slow cooker. Stir in the 1 tablespoon brown sugar and 0.5 teaspoon red pepper flakes.
Step 3: Slow Cook with Bell Peppers
Add the 3 whole bell peppers (sliced into strips) to the slow cooker, stirring to combine with the beef and sauce. Cover and cook on low heat for 6-7 hours or on high heat for 3-4 hours, until the beef is fork-tender.
Resist the urge to lift the lid during cooking—every peek extends the cooking time. The beef should easily pull apart with a fork when done, and the peppers will soften beautifully in the rich, aromatic sauce.
Step 4: Thicken the Sauce to Finish
In a small bowl, whisk the 2 tablespoons cornstarch with 2 tablespoons cold water until smooth. Stir this slurry into the slow cooker during the last 30 minutes of cooking.
This final step transforms the sauce from thin to luscious, coating the beef and peppers perfectly. Serve the pepper steak hot over rice or noodles, ensuring every bite delivers that promised tenderness with a vibrant, slightly sweet-savory sauce.
Pro Tips For Making Pepper Steak Recipe Crock Pot Pioneer Woman
- Sear the Beef First: I learned this the hard way—browning the round steak in a hot skillet for 2-3 minutes per side before it hits the crock pot adds depth the slow cooker can’t replicate on its own.
- Slice Against the Grain: After watching my steak turn chewy too many times, I now slice the beef thinly against the grain before cooking—makes it melt-in-your-mouth tender even with budget round steak.
- Don’t Drown the Peppers: Add the bell peppers during the last 1-2 hours of cooking instead of at the start, or they’ll turn to mush and lose that crisp bite that balances the dish.
- Deglaze the Pan: After searing the beef, pour a splash of the beef broth into the skillet to scrape up those browned bits, then add it to the crock pot—it’s where half the flavor lives.
