Step‑by‑Step Instructions for Slow Cooker Pepper Steak
Step 1: Prep the Beef
Begin by slicing your beef sirloin into thin strips, about 1/4 inch thick, ensuring even cooking. Pat the beef dry with paper towels and season generously with salt and pepper. This seasoning step enhances the flavor of the meat, making it deliciously savory in your Slow Cooker Pepper Steak.
Step 2: Layer Ingredients
In a slow cooker, layer the seasoned beef at the bottom, allowing the juices to flavor the dish. Next, add sliced onions and vibrant bell peppers on top, creating a colorful base. This layering helps infuse the vegetables with the beef’s juices and flavor as they cook together on low heat.
Step 3: Mix the Sauce
In a separate bowl, whisk together minced garlic, beef broth, bouillon cubes, soy sauce, honey, Worcestershire sauce, and ground ginger until well combined. This rich sauce is the heart of your Slow Cooker Pepper Steak, adding depth and a delightful aroma to the dish.
Step 4: Pour and Cook
Pour the sauce evenly over the layered beef and vegetables in the slow cooker. Cover the slow cooker with its lid and set to cook on LOW for 6–8 hours or HIGH for 3–4 hours. You’ll know it’s ready when the beef is fork-tender and the vegetables are soft, creating a comforting meal.
Step 5: Thicken the Sauce (if necessary)
If you prefer a thicker sauce for your Slow Cooker Pepper Steak, mix cornstarch with a bit of cold water to create a slurry. About 10–15 minutes before serving, stir this mixture into the slow cooker, setting it to HIGH to thicken the sauce, stirring occasionally until bubbling.
Step 6: Serve
As your Slow Cooker Pepper Steak finishes up, prepare to serve this delightful dish over rice, noodles, or mashed potatoes. For a burst of flavor and garnish, sprinkle sesame seeds or chopped green onions on top. Enjoy the warm, hearty comfort of a meal that brings everyone to the table!

Make Ahead Options
These Slow Cooker Pepper Steak ingredients are perfect for meal prep enthusiasts! You can slice the beef and chop the onions and bell peppers up to 24 hours in advance; simply store them separately in airtight containers in the refrigerator to keep them fresh. The sauce can also be prepared ahead and stored in the fridge for up to 3 days—just whisk together the garlic, broth, and seasonings, pour it into a jar, and refrigerate. When you’re ready to cook, layer everything in the slow cooker and let it do the magic. This makes dinner a breeze after a busy day, ensuring every bite is just as delicious as when made fresh!
