How to Make Pepper Steak in a Crock Pot Recipe
Step 1: Prepare the Beef
Start by slicing your beef sirloin or flank steak into thin strips. This is key to ensuring the meat becomes tender and soaks up all those incredible flavors during slow cooking. Placing the beef at the bottom of your crock pot creates the perfect foundation for the sauce and vegetables to meld together.
Step 2: Mix the Sauce
In a small bowl, whisk together the cornstarch, soy sauce, beef broth, brown sugar, sesame oil, minced garlic, ground ginger, and black pepper until everything is smooth and well combined. This sauce is the soul of the dish, offering a beautiful balance of savory, sweet, and aromatic notes that will infuse the beef and veggies as they cook slowly.
Step 3: Combine and Add Vegetables
Pour the sauce over the beef in the slow cooker and gently stir to coat the strips evenly. Then layer your vibrant red and green bell peppers along with the sliced onion on top. These vegetables add essential texture, sweetness, and a pop of color that makes this Pepper Steak in a Crock Pot Recipe truly irresistible.
Step 4: Slow Cook to Perfection
Cover and cook on low for 5 to 6 hours, or if you’re short on time, set it to high for 2.5 to 3 hours. The slow cooking process tenderizes the beef beautifully while allowing the vegetables to soften yet maintain a pleasant bite. The aroma during cooking will have you eagerly awaiting the moment you can dig in.
Step 5: Final Stir and Serve
Before serving, give everything a gentle stir to mix the flavors just right, ensuring every bite is coated with that luscious sauce. Serve hot over fluffy rice or your favorite noodles for a complete meal that’s deeply satisfying and packed with flavor.
