How to Make Crock Pot Pepper Steak {Low Carb, Gluten Free} Recipe

Step 1: Prepare the Sauce Mixture

Start by combining the gluten-free soy sauce or coconut aminos, Worcestershire sauce, sesame oil, minced garlic, fresh grated ginger, brown sugar, and crushed red pepper in a small bowl. This mixture is the heart of your Crock Pot Pepper Steak {Low Carb, Gluten Free} Recipe, blending savory, sweet, and spicy notes to infuse every bite with richness.

Step 2: Layer the Ingredients in the Crock Pot

Place the thinly sliced sirloin steak strips and the freshly sliced vegetables—green peppers, mushrooms, and onions—into the Crock Pot. Keeping the sizes consistent helps the steak and veggies cook evenly, giving you the perfect texture in every spoonful.

Step 3: Add the Sauce

Pour your carefully mixed sauce over the meat and vegetable layers. The sauce will gently seep through the ingredients as it cooks, marrying the flavors and tenderizing the steak for that melt-in-your-mouth sensation.

Step 4: Slow Cook to Perfection

Set your Crock Pot to low and cook for 4 hours, or choose high for 2 hours if you’re pressed for time. Slow cooking here is crucial—it transforms the sirloin into tender strips that soak up every bit of the luscious sauce without turning mushy.

Step 5: Serve and Enjoy

Once cooked, serve your Crock Pot Pepper Steak {Low Carb, Gluten Free} Recipe over rice or your favorite low carb alternative. The sauce will be thick and flavorful, perfectly complementing whatever base you choose.
