Slow Cooker Pepper Steak – A Comfort-Food Classic Made Easy

There is something magical about a dish that delivers fall-apart tender beef, vibrant peppers, and a bold, glossy sauce—all created without hovering over a stove. Slow Cooker Pepper Steak is the perfect marriage of comfort food and easy home cooking, bringing restaurant-quality flavor straight to your kitchen. The aroma alone—garlic, caramelized onion, rich beef, and soy-based umami—makes this dish absolutely impossible to resist. Every bite delivers a balance of sweet and savory depth, pepper-studded warmth, and silky gravy that clings to rice, noodles, or mashed potatoes like a dream.

What makes this recipe truly irresistible is its simplicity. The slow cooker does the heavy lifting, turning lean steak into melt-in-your-mouth strips while infusing the sauce with deep, layered flavor. It’s the dish families request on repeat, meal-preppers rely on weekly, and busy home cooks praise for being effortless yet unforgettable. If you love takeout-style pepper steak, but want a healthier, richer, more affordable version at home, this recipe is your new secret weapon.

Ingredients & What Each One Does

• Beef sirloin or flank steak – The protein base and star of the dish; sliced into thin strips so it cooks into buttery, tender bites.
• Green bell peppers – Add earthy sweetness and maintain structure for a satisfying fresh crunch.
• Red bell peppers – Slightly sweeter than green peppers, delivering natural sugar balance and beautiful color for visual appeal.
• Yellow onion – Slowly caramelizes to build a deep aromatic base and adds mellow sweetness to the sauce.
• Garlic cloves – Infuse the gravy with warm savory intensity and amplify the umami foundation.
• Soy sauce – The primary flavor backbone; delivers salty richness, complex depth, and a takeout-style profile.
• Beef broth – Keeps the steak juicy while forming a rich, silky cooking liquid that becomes the gravy.
• Brown sugar – Adds caramelized sweetness to balance salt and boost glossy slow-cooked flavor.
• Ground black pepper – The defining spice; provides gentle heat, woodsy warmth, and signature pepper steak bite.
• Olive oil – Used for searing; creates Maillard browning for a more intense beef flavor.
• Cornstarch + water slurry – The thickener that turns liquid into a luxurious glossy gravy with perfect cling.
• Optional sesame oil – Adds nutty aroma and restaurant-style finishing richness.

Step-by-Step Instructions

1. Slice your steak into thin strips against the grain to ensure maximum tenderness.
2. Heat olive oil in a skillet over medium-high heat and sear beef for 1–2 minutes per side for deeper flavor.
3. Place beef strips, onion slices, and bell peppers into the slow cooker in even layers.
4. Whisk together soy sauce, beef broth, brown sugar, minced garlic, and black pepper. Pour over beef and vegetables.
5. Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours until beef is fork-tender.
6. Mix cornstarch and water into a slurry and stir it into the sauce during the last 20 minutes to thicken.
7. Serve hot over rice, noodles, or potatoes, spooning sauce generously over the top.
