Step‑by‑Step Instructions for Slow Cooker Pepper Steak
Step 1: Prep the Beef
Begin by slicing the beef sirloin into even strips, ensuring uniform cooking. Pat the pieces dry with a paper towel and season generously with salt and pepper to enhance the flavor. Set aside the seasoned beef as you prepare the vegetables, creating a strong flavor base for your Slow Cooker Pepper Steak.
Step 2: Layer Ingredients
In your slow cooker, place the seasoned beef at the bottom, allowing it to soak up the flavors from the sauce. Next, chop onions and bell peppers into bite-sized pieces, and layer them over the beef. This layering technique helps to create a beautiful, colorful presentation and ensures that the vegetables infuse their flavors into the dish while cooking.
Step 3: Mix Sauce
In a medium bowl, whisk together the minced garlic, beef broth, crumbled bouillon cubes, soy sauce, honey or brown sugar, Worcestershire sauce, ground ginger, salt, and pepper until the mixture is smooth and well combined. This savory sauce will coat the beef and vegetables, adding depth to the Slow Cooker Pepper Steak.
Step 4: Pour Sauce
Carefully pour the prepared sauce over the layers of beef and vegetables in the slow cooker. Make sure the sauce is evenly distributed to ensure each bite of Slow Cooker Pepper Steak is bursting with flavor. This rich sauce is key to creating a mouthwatering final dish that will delight your family.
Step 5: Cook
Cover the slow cooker with its lid and set it to cook on LOW for 6-8 hours or HIGH for 3-4 hours. The goal is to let the beef simmer until it becomes fork-tender, and the flavors meld beautifully, creating a comforting meal that fills your kitchen with aromatic scents.
Step 6: Thicken Sauce
If you prefer a thicker sauce for your Slow Cooker Pepper Steak, mix cornstarch with a bit of cold water in a small bowl until smooth. Stir this mixture into the slow cooker during the last 10-15 minutes of cooking while keeping the lid off. This will allow the sauce to thicken and achieve that velvety consistency you desire.
Step 7: Serve
Once ready, ladle the hot Slow Cooker Pepper Steak over a bed of fluffy rice, egg noodles, or creamy mashed potatoes for a heartwarming meal. For an extra touch of flavor, garnish with freshly chopped green onions or a sprinkle of sesame seeds, completing your delightful dining experience.
