- Slice the Steak: Cut the flank steak or sirloin into thin strips, about 1-inch wide. Season with salt and pepper.
- Chop the Vegetables: Slice the onion and bell peppers into strips. Mince the garlic.
Step 2: Brown the Steak (Optional)
For added depth of flavor, you can brown the steak before adding it to the slow cooker:
- Heat Olive Oil: In a skillet over medium-high heat, add the olive oil.
- Brown the Steak: In batches, add the steak strips and sear until browned on all sides (about 2-3 minutes). Remove from heat and transfer to the slow cooker.
Step 3: Add Vegetables and Sauce
- Layer the Vegetables: Add the sliced onion, bell peppers, and minced garlic on top of the browned steak in the slow cooker.
- Make the Sauce: In a separate bowl, whisk together the beef broth, soy sauce, cornstarch, brown sugar, Worcestershire sauce, ground ginger, black pepper, and sesame oil (if using) until smooth.
- Pour the Sauce: Pour the sauce evenly over the steak and vegetables in the slow cooker.
Step 4: Cook the Pepper Steak
- Set the Slow Cooker: Cover and cook on low for 6-8 hours or on high for 3-4 hours. The beef should be tender and the vegetables cooked but still vibrant.
Step 5: Serve and Enjoy
- Thicken the Sauce (if needed): If you’d like a thicker sauce, remove the lid in the last 30 minutes of cooking to let it reduce, or mix an additional tablespoon of cornstarch with a little water and stir it into the sauce.
- Serve: Serve the pepper steak over steamed rice, noodles, or even cauliflower rice for a low-carb option. Garnish with sliced green onions or sesame seeds for an added touch.
Tips and Variations:
- Add Vegetables: Feel free to include other vegetables like snap peas, carrots, or broccoli for extra color and nutrition.
- Spice it Up: For a little heat, add sliced jalapeños or red pepper flakes to the slow cooker.
- Make it a Meal Prep: This dish stores well in the refrigerator for 3-4 days and can be frozen for longer storage.
