Holly’s Recipe Highlights: Slow Cooker Pepper Steak

Flavor: Savory and slightly sweet, with an Asian vibe from ginger and garlic, rich beef flavor, and just a touch of heat.
Why It Works: Skip the skillet and browning. Just add the beef, vegetables, and sauce to the slow cooker and let it do all the work.
Serving Suggestions: Spoon over fluffy white rice or baked brown rice, or serve over soba or udon noodles with a side of steamed broccoli.

Ingredients Notes

broth , peppers , onion , cornstarch , soy sauce , flank steak , ginger , Worcestershire , red pepper flakes , garlic powder , honey , sesame seeds with labels to make Slow Cooker Pepper Steak

Flank Steak or Sirloin Steak: Both work well, but flank steak is especially flavorful.
Bell Peppers: I like to use a mix of different colors. Add them towards the end of the cooking time for a crisp texture.
Fresh Ginger: Freshly minced ginger gives the sauce the best flavor, but dry ground ginger works too.
Soy Sauce: This adds the savory, umami flavor to the sauce. Use regular or reduced-sodium soy sauce.
Honey: A little honey balances the salty soy sauce and adds a touch of sweetness. Replace with brown sugar with similar results.

Slice Against the Grain: Slicing the beef against the grain is the key to getting tender strips of steak. Use a sharp knife and cut across the muscle fibers.
Adding the Peppers: For softer bell peppers, add them at the beginning of the cooking time. For tender-crisp bell peppers, add them during the last hour of cooking.
Thicken on High: Create a slurry, and mix the cornstarch with cold water before stirring it into the cooking liquid, and add it 20-30 minutes before cooking time is complete.
Rest Before Serving: Once thickened, let it set uncovered for a few minutes so the sauce clings to the beef strips when serving.

Storing Leftovers

Refrigerate: Transfer leftovers to an airtight container and use within 4 days.
Freeze: Freeze cooled pepper steak in airtight, freezer-safe containers or zippered bags for up to 4 months. Defrost overnight in the refrigerator.
Reheat: Reheat individual portions in the microwave or on the stovetop on low heat. Remove from heat promptly to avoid overcooking.
