How to Make Slow Cooker Pepper Steak

Step 1: Prepare the Ingredients

Start by slicing the beef into thin strips against the grain to ensure tenderness after slow cooking. Chop the bell peppers and onion into bite-sized strips, and mince the garlic for that fragrant touch.

Step 2: Sauté Beef and Vegetables

In a large skillet, heat olive oil over medium-high heat. Quickly sear the beef strips until browned on all sides, then set aside. In the same skillet, sauté the onions, garlic, and bell peppers just until they start to soften, releasing their natural sweetness.

Step 3: Combine Ingredients in the Slow Cooker

Transfer the beef and sautéed vegetables to the slow cooker. Add vegetarian Worcestershire sauce (natural), grape juice, beef broth, and freshly ground black pepper. Stir everything together to combine flavors evenly.

Step 4: Cook Low and Slow

Cover your slow cooker and cook on low for 6 to 8 hours, allowing the beef to become tender and the flavors to mingle beautifully. The low temperature gently breaks down the meat for that perfect softness.

Step 5: Thicken the Sauce

About 30 minutes before serving, mix cornstarch or a natural gelling agent with cold water to make a slurry. Stir this into the slow cooker and let it thicken the sauce to a luscious, glossy consistency. Give it a good stir, then allow the sauce to finish cooking.

Pro Tips for Making Slow Cooker Pepper Steak

• Thin slices: Cut the beef thinly across the grain to maximize tenderness after slow cooking.
• Don’t skip the sauté: Browning the beef and veggies adds a depth of flavor that is crucial to this dish.
• Use fresh black pepper: Ground fresh black pepper right before cooking enhances the signature pepper steak taste.
• Timing matters: Slow cook on low to avoid drying out the beef and to develop the richest flavor.
• Thicken last: Add the slurry near the end of cooking to avoid a clumpy sauce texture.
