We’ll show you the secret to getting that perfectly tender beef and a sauce so good you’ll want to pour it over everything. Perfect for serving over fluffy rice or noodles, this is a dish your whole family will ask for again and again.
Why This Slow Cooker Pepper Steak Recipe Works
Forget tough, chewy beef and watery sauces. This recipe is foolproof, and here’s why: the low-and-slow cooking method breaks down the beef until it’s melt-in-your-mouth tender. The sauce ingredients meld together over several hours, creating a depth of flavor that you just can’t achieve with a quick stir-fry. We also wait to add the peppers until the end, ensuring they stay vibrant and crisp-tender, not mushy. It’s the perfect balance of flavor, texture, and convenience.
The Best Ingredients for Pepper Steak
The magic of this dish lies in its simple, accessible ingredients. Quality matters, so let’s break down what you’ll need.
What Cut of Beef is Best?
For the most tender Slow Cooker Pepper Steak, we recommend using beef sirloin or flank steak. Both cuts are lean yet flavorful and become incredibly tender when cooked low and slow. Slice the beef thinly against the grain to ensure every bite is easy to chew. You can also use round steak, but sirloin or flank will give you the best results.

Peppers, Onions, and Aromatics
A vibrant mix of bell peppers not only adds beautiful color but also layers of flavor. We use a combination of red, green, and yellow bell peppers, along with a sweet yellow onion. Fresh garlic and ginger are non-negotiable for that aromatic, savory base that makes the sauce so addictive.
The Perfect Pepper Steak Sauce
The sauce is a simple but powerful combination of low-sodium soy sauce, beef broth, sesame oil, and a touch of brown sugar for balance. A cornstarch slurry is added at the end to transform it into a thick, glossy sauce that clings perfectly to the beef and peppers.
How to Make Slow Cooker Pepper Steak (Step-by-Step)
This recipe is as easy as 1-2-3. Follow these simple steps for perfect pepper steak every time.
- Prepare the Beef: Pat the steak dry and slice it thinly against the grain, about 1/4-inch thick. This is the most crucial step for tender results!
- Make the Sauce: In the bottom of your slow cooker, whisk together the beef broth, soy sauce, brown sugar, sesame oil, minced garlic, and grated ginger.
- Combine and Cook: Add the sliced beef and onions to the slow cooker. Stir everything together to ensure the beef is coated in the sauce. Cover and cook on low for 4-5 hours or on high for 2-3 hours.
- Add the Peppers: About 30-45 minutes before serving, add the sliced bell peppers to the slow cooker. Stir them in and continue to cook until they are crisp-tender.
- Thicken the Sauce: In a small bowl, whisk together the cornstarch and cold water to create a slurry. Pour it into the slow cooker and stir gently. The sauce will thicken as it heats. Serve immediately.

Tips for the Most Tender Pepper Steak
For beef that truly melts in your mouth, always slice against the grain. Look for the lines (the grain) in the muscle and cut perpendicular to them. This shortens the muscle fibers, making the meat much more tender. Also, be careful not to overcook it. Even in a slow cooker, beef can become tough if cooked for too long, so stick to the recommended cooking times.
How to Thicken the Sauce
The key to a perfect, glossy sauce is a cornstarch slurry. It’s essential to mix the cornstarch with cold water before adding it to the slow cooker. If you add cornstarch directly to hot liquid, it will clump up. Whisk the slurry in during the last 15-20 minutes of cooking and let it heat through to activate its thickening power. You’ll be left with a rich sauce that’s perfect for spooning over rice.

Freezing Pepper Steak
You can freeze pepper steak for up to 3 months. For best results, let it cool completely and store it in a freezer-safe, airtight container or a zip-top bag.
