This slow cooker steak and peppers recipe is an easy crock pot dinner made with sirloin This easy slow cooker steak and peppers recipe uses tender sirloin steak with bell peppers and onions simmered in a savory soy-ginger sauce. It’s a family-friendly crock pot dinner that’s best served over rice to soak up all the flavorful sauce.

The flavor here is really good, but I want to be upfront about texture because that matters with peppers in the slow cooker. They do soften more than they would in a skillet or stir fry. If you prefer firmer peppers, cut them very thick, at least 1 inch or more, so they hold up better during the long cook time.
I used a thin cut beef sirloin tip steak, which worked well and stayed tender. You can also start with a thicker cut of sirloin and slice it thin yourself. Right before serving, I added a small handful of chopped fresh parsley, which is more of a personal preference.
Ingredients
- 2 pounds beef sirloin steak, thin cut into 1 inch strips
- 3/4 cup hot beef broth
- 3 beef bouillon cubes
- 1/4 cup soy sauce
- 2 tablespoons honey
- 1 tablespoon Worcestershire sauce
- 1 teaspoon ground ginger
- 1/2 teaspoon ground black pepper
- 1/2 teaspoon salt
- 2 tablespoons cornstarch
- 3 bell peppers (red, yellow, and orange), seeds removed and sliced thick
- 1 yellow onion, sliced
- Cooked rice, for serving

How to Make Slow Cooker Steak and Peppers
Add the sliced steak to the bottom of a slow cooker and spread it out evenly.
In a small bowl, add the hot beef broth and dissolve the bouillon cubes, crushing and stirring until completely dissolved. Add the soy sauce, honey, Worcestershire sauce, ground ginger, black pepper, and salt. Mix well.
Whisk the cornstarch into the liquid mixture until smooth, then pour it evenly over the steak in the slow cooker.

Add the thick sliced bell peppers and sliced onion on top of the beef. Do not stir.
Cover and cook on low for 6 hours or on high for 3 hours, until the steak is tender and the sauce has thickened.
Serve hot over rice. Garnish with chopped fresh parsley if desired.

Pepper Texture Notes
Because this recipe cooks for several hours, the peppers will soften more than they would in a skillet. If you like firmer peppers, cut them very thick or add them during the last hour of cooking.
Thinly sliced peppers will become very soft by the end of the cook time.
Serving Suggestions
This slow cooker steak and peppers is best served over steamed rice, which pairs perfectly with the savory soy-ginger sauce.
For a complete Asian-inspired dinner spread, try serving it alongside:
- Jasmine Fried Rice — fragrant rice that soaks up the sauce.
- Broccoli Mushroom Stir Fry — a simple veggie side with savory flavor and texture.
- Garlic Sesame Noodles — savory noodles that complement the steak and peppers
Leftovers reheat well, and the flavor continues to develop after sitting overnight.
