How to Make Slow Cooker Pepper Steak Recipe
Step 1: Prepare the Flavorful Sauce
Start by combining the hot beef broth with bouillon cubes, soy sauce, Worcestershire sauce, honey, ground ginger, black pepper, salt, and cornstarch in a mixing glass. Give it a good stir, making sure to crush the bouillon cubes completely. This mixture is the magic potion that will infuse the beef and vegetables with rich, inviting flavors as they slow cook together.
Step 2: Layer Your Ingredients
Place your beef sirloin strips gently into the slow cooker first—this allows them to soak in the sauce as it cooks. Pour the prepared sauce all over the beef, ensuring every strip is coated. Now add the thick slices of bell peppers, onions, and garlic on top. This layering keeps the peppers and onions tender yet just the right amount of bite, perfectly complementing the beef’s softness.
Step 3: Slow Cook to Perfection
Set your slow cooker to LOW for about 6 hours or HIGH for 3 hours. If you can, give the mix a gentle stir halfway through cooking to evenly distribute the sauce and meld all those wonderful flavors together. The slow cooking process transforms the beef into tender pieces that soak up that delicious sauce, while the vegetables release their juices and soften just right.
Step 4: Serve with Love
Once cooked, stir everything well to combine all the flavors one last time. Transfer the pepper steak to a serving dish, letting the gorgeous colors and the inviting smell do the rest of the work. It’s time to gather your favorite sides or carbs and enjoy a meal that tastes like it took all day but required very little effort.

Garnishes
Add a fresh twist by garnishing with chopped green onions or a sprinkle of toasted sesame seeds. These little touches add brightness and a hint of crunch that enhance the overall experience without overpowering the natural flavors of the dish.
Side Dishes
Slow Cooker Pepper Steak Recipe pairs beautifully with simple and comforting sides. Serve it over fluffy white or brown rice to soak up every bit of sauce. Alternatively, wide egg noodles, mashed potatoes, or even buttery baked potatoes are excellent options that complement the savory richness.
Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
You can store any leftover Slow Cooker Pepper Steak Recipe in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, making the next day’s meal just as tasty, if not more.
Freezing
If you want to keep this delicious dish for later, freezing works well. Allow the pepper steak to cool completely, then transfer it to a freezer-safe container or heavy-duty freezer bag. It will stay fresh and flavorful for up to 3 months, so you can enjoy your favorite slow cooker meal anytime with minimal prep.
Reheating
Reheat leftovers gently on the stovetop over medium-low heat or in the microwave, stirring occasionally to warm through evenly. If the sauce becomes too thick after refrigeration, add a splash of beef broth or water to loosen it back up and keep the beef tender and juicy.
FAQs
Can I use a different cut of beef for this Slow Cooker Pepper Steak Recipe?
Absolutely! While sirloin is ideal for its tenderness and flavor, other cuts like flank steak or skirt steak can also work well. Just slice them thinly against the grain to ensure tenderness once cooked.
Is it possible to make this recipe without soy sauce?
Yes, you can substitute soy sauce with coconut aminos for a gluten-free alternative or use tamari. Each will slightly alter the flavor but keep that essential umami depth.
Can I add other vegetables to this dish?
Definitely! Mushrooms, snap peas, or thinly sliced carrots can be wonderful additions. Add them halfway through cooking to prevent them from getting too soft or mushy.
Do I need to thicken the sauce with cornstarch?
It’s highly recommended as it creates a luscious sauce that coats the beef and vegetables beautifully. If you prefer a thinner sauce, you can reduce or omit the cornstarch, but expect a more broth-like consistency.
Can I double this Slow Cooker Pepper Steak Recipe for a larger group?
Yes, this recipe scales up nicely. Just make sure your slow cooker is large enough to accommodate extra ingredients without overcrowding, which could affect cooking times and results.
