How to Make Crockpot Pepper Steak β Step By Step
Step 1: Prepare the Ingredients
Start by washing and slicing your bell peppers into thin strips. Chop the onion into similar-sized slices, and mince the garlic cloves. Make sure your flank steak is cut into even strips for consistent cooking. Gather all other ingredients within arm’s reach to streamline your cooking process.
Step 2: SautΓ© the Beef
In a skillet, heat olive oil over medium-high heat. Add the steak strips and sautΓ© until they’re just browned on the outside. You donβt want to cook them through; just give them a quick sear to lock in the flavors. Remove the beef and set it aside.
Step 3: Combine Ingredients in the Crockpot
In your crockpot, combine the sliced peppers, onion, garlic, soy sauce, beef broth, and tomato paste. Stir in the browned steak strips. Season the mix with salt, pepper, and Italian seasoning to enhance the flavors.
Step 4: Cook and Simmer
Cover your crockpot and set it to cook on low for 6β8 hours or on high for 3β4 hours. This slow cooking method allows the meat to become tender and the flavors to meld together wonderfully.
Step 5: Thicken the Sauce
About 30 minutes before youβre ready to serve, mix a tablespoon of cornstarch with some water to make a slurry. Stir this into the crockpot to thicken the sauce, letting it cook uncovered until you reach the desired sauce consistency.
How to Serve Crockpot Pepper Steak
Serve this delectable Crockpot Pepper Steak over steamed rice or cauliflower rice, perfect for soaking up all the flavorful juices. For a well-rounded meal, pair it with a side of fresh salad or steamed vegetables.
Recipe Success Tips & Suggestions
To enhance the flavor, consider marinating the steak strips in soy sauce, garlic, and ginger overnight before cooking. This will add an extra depth of taste. If you like a little heat, add some sliced jalapeΓ±os or red pepper flakes for a spicy kick.
