- 2 pounds beef sirloin, cut into 2-inch strips: Choose a good quality cut for the best tenderness after slow cooking.
- 3/4 teaspoon garlic powder: Adds subtle, aromatic depth to the beef seasoning.

- 1/4 cup hot water: Helps dissolve the bouillon and cornstarch for the sauce base.
- 1 tablespoon cornstarch: Thickens the sauce beautifully, giving it that perfect luscious texture.
- 1/2 cup chopped onion: Adds slight sweetness and a tender crunch.
- 2 large green bell peppers, roughly chopped: Brings vibrant color and a fresh, slightly sweet bite.
- 1 (14.5 ounce) can stewed tomatoes, with liquid: Introduces a tangy, juicy base that melds all the flavors.

How to Make Pepper Steak in a Crock Pot Recipe
Step 1: Season and Sear the Beef
Start by sprinkling the beef sirloin strips evenly with garlic powder to layer in some garlic flavor right from the start. Heat the vegetable oil in a large skillet over medium heat, then sear the beef strips for about 5 minutes on each side until they develop a nice brown crust. This step is absolutely key—it locks in the juices and creates a deeper flavor foundation before slow cooking. Once seared, transfer the beef strips to your slow cooker.
Step 2: Prepare the Sauce Mixture
Next, dissolve the beef bouillon cube in 1/4 cup of hot water. This will give your sauce a rich, meaty backbone. Stir in the cornstarch until everything is fully dissolved, which will ensure your sauce thickens perfectly by the end. Pour this mixture over the seared beef in your crock pot to coat every delicious strip in savory goodness.
Step 3: Add Vegetables and Seasonings
Now it’s time for the fresh and flavorful components that make this Pepper Steak in a Crock Pot Recipe so irresistibly colorful and tasty. Stir in the chopped onions, roughly chopped green bell peppers, and the canned stewed tomatoes with their juices. Add the soy sauce, white sugar, and salt to bring everything together with a harmonious balance of sweet, salty, and tangy flavors.
Step 4: Set Your Slow Cooker
Cover the slow cooker and cook on High for 3 to 4 hours or on Low for 6 to 8 hours. This slow, gentle heat breaks down the beef’s fibers to melt it tender and allows all those vibrant flavors to mingle and develop into a hearty, comforting dish.
Step 5: Serve and Enjoy
Once the beef is tender and the sauce has thickened to a glossy perfection, it’s time to serve. This Pepper Steak in a Crock Pot Recipe shines when spooned over warm, fluffy rice or your favorite noodles—it’s the perfect way to soak up the savory sauce.

Garnishes
A sprinkle of freshly chopped parsley or green onions adds a fresh burst of color and flavor that elevates the dish visually and taste-wise. For a little extra crunch and color contrast, try toasted sesame seeds—they bring a delightful nuttiness that pairs wonderfully with the soy sauce base.
Side Dishes
Serve this Pepper Steak alongside steamed jasmine rice or buttery egg noodles to make a complete meal that’s hearty and satisfying. If you prefer more veggies, a simple sauté of broccoli or snap peas works beautifully to complement the rich flavors of the steak.
Creative Ways to Present
For a fun twist, try serving the pepper steak over cauliflower rice for a low-carb option or stuff it inside a warm pita pocket with some crisp lettuce and a dollop of sour cream for a handheld delight. It’s a wonderfully versatile recipe that lets you get creative with presentation and sides.
Make Ahead and Storage
Storing Leftovers
Leftover Pepper Steak in a Crock Pot Recipe keeps beautifully in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, making it even tastier the next day.
Freezing
If you want to freeze leftovers, let the dish cool completely before transferring it into a freezer-safe container. It freezes well for up to 2 months. Just thaw overnight in the fridge before reheating to preserve the tender texture of the beef.
Reheating
To reheat, warm the pepper steak gently in a saucepan over low to medium heat, stirring occasionally to prevent sticking, until heated through. You can add a splash of water or broth if the sauce feels too thick after refrigeration.
FAQs
Can I use a different cut of beef for this recipe?
Absolutely! While sirloin is ideal because it stays tender with slow cooking, you can use flank steak or even stew beef. Just be mindful of cook times, as tougher cuts may need a bit longer to become tender.
Is it necessary to sear the beef before slow cooking?
While you can skip searing for convenience, taking the time to brown the beef first really amps up the flavor and locks in juices, making your Pepper Steak in a Crock Pot Recipe much more delicious.
Can I make this recipe in an Instant Pot?
Yes! You can brown the beef using the sauté function, then pressure cook the ingredients for about 30 minutes followed by a natural release. It’s a quicker alternative with great results.
What can I use instead of bell peppers?
If you’re not a fan of green bell peppers, red or yellow ones work great too and add a slightly sweeter flavor. You can also experiment with poblano or even mild chili peppers for an extra kick.
Can this dish be made vegan or vegetarian?
To make a vegan version, substitute the beef with hearty mushrooms or tofu, use vegetable broth instead of beef bouillon, and check that the soy sauce you use is vegan-friendly. The flavors will still be wonderfully rich and satisfying.
