How To Make Slow Cooker Pepper Steak

This Slow Cooker Pepper Steak balances simple prep with hands-off cooking to deliver tender, flavorful results. You’ll start by searing the beef, then layer in sautéed veggies and a rich soy-ginger broth before letting the slow cooker work its magic. Follow these steps for a glossy, melt-in-your-mouth dish:

1. Begin by heating the olive oil in a skillet over medium-high heat. Once shimmering, add the sliced beef flank steak in batches, searing until browned on all sides—this caramelization builds a robust flavor base.

2. Once the beef is well-browned, transfer it to the slow cooker, scraping up any flavorful browned bits from the skillet to add into the pot.

3. In the same skillet, add the sliced onions and bell peppers. Sauté for about 3–4 minutes until they start to soften, stirring occasionally, then stir in the minced garlic and cook for another minute until fragrant.

4. Pour the sautéed vegetables over the beef in the slow cooker, layering in those softened peppers and onions.

5. In a separate bowl, whisk together the beef broth, soy sauce, brown sugar, black pepper, and grated ginger until fully combined. Pour this mixture over the beef and vegetables to create a rich braising sauce.

6. Cover the slow cooker and set it to low heat for 4–6 hours or high heat for 2–3 hours, allowing the beef to become tender and the flavors to meld.

7. About 30 minutes before serving, whisk together the cornstarch and water in a small bowl to create a smooth slurry. Stir this into the slow cooker to thicken the sauce, then allow it to cook for the remaining time.

8. Once the beef is fork-tender and the sauce is glossy, serve the pepper steak over cooked rice and garnish with sliced green onions if desired.

Frequently Asked Questions

Got questions? We’ve got answers to help you cook your best Slow Cooker Pepper Steak yet!

• How long does it take to prepare and cook this slow cooker pepper steak?

Prep time is about 20–25 minutes, which includes slicing the steak and vegetables, searing the beef, and sautéing the peppers and onions. Cook time is 4–6 hours on low or 2–3 hours on high in the slow cooker. Plan on a total of roughly 5–6 hours on low (or 3 hours on high) from start to finish.

• Can I use a different cut of beef besides flank steak?

Yes, you can substitute sirloin, skirt steak, or chuck roast. Sirloin and skirt will cook more quickly and remain tender, so check for doneness toward the lower end of the cooking window. Chuck roast benefits from the full cook time on low to break down connective tissue and become melt-in-your-mouth tender.

• How do I ensure the sauce is thick and not too watery?

About 30 minutes before the end of cooking, whisk together 2 tablespoons of cornstarch with 2 tablespoons of water to form a slurry. Stir it into the slow cooker and continue cooking. The residual heat will activate the cornstarch, yielding a glossy, thickened sauce. If it’s still too thin, remove the lid and cook on high for 15–20 minutes to reduce further.

• Can I add other vegetables to this recipe?

Absolutely. Broccoli florets, snap peas, sliced carrots, or mushrooms work well. Add heartier vegetables like carrots or broccoli at the start so they soften fully, and more delicate ones like snap peas in the last hour to retain crunch. Adjust sauté time in the skillet accordingly to avoid overcooking.

• How should I store and reheat leftovers?

Let the pepper steak cool to room temperature, then transfer to an airtight container and refrigerate for up to 3 days. To reheat, warm gently on the stovetop over medium heat, stirring in a splash of beef broth or water to revive the sauce. You can also microwave single servings in 30-second intervals, stirring between each, until heated through.

• Is it possible to make this recipe gluten-free?

Yes. Use tamari or a certified gluten-free soy sauce in place of regular soy sauce, and confirm your beef broth is gluten-free. Cornstarch is naturally gluten-free, so the slurry remains unchanged. Your slow cooker pepper steak will retain its flavor and thickness without gluten.

• What are your best tips for perfectly searing the beef before slow cooking?

Pat steak strips dry with paper towels to remove excess moisture—this promotes browning. Heat the skillet until it’s very hot, then add the olive oil and beef in a single layer. Work in batches to avoid overcrowding, which traps steam. Sear for 1–2 minutes per side until a golden crust forms, then transfer strips to the slow cooker immediately to preserve that depth of flavor.
