Tools & Equipment Needed

• Slow cooker (crock pot)
• Large skillet (for searing beef)
• Sharp knife
• Cutting board
• Mixing bowl
• Wooden spoon or spatula
• Measuring cups and spoons

Optional but helpful:

• Garlic press
• Microplane for ginger

Step-by-Step Instructions

1. Sear the Beef

Heat 1 tablespoon olive oil in a skillet over medium-high heat. Add the beef strips and quickly sear for 2–3 minutes until lightly browned. This step locks in flavor and adds depth to the Keto Pepper Steak sauce.

2. Transfer to Slow Cooker

Place the seared beef directly into the slow cooker, spreading it evenly across the bottom.

3. Add Vegetables

Layer sliced onions, bell peppers, minced garlic, and grated ginger over the beef. These aromatics will slowly infuse the dish as it cooks.

4. Prepare the Sauce

In a bowl, combine coconut aminos, Worcestershire sauce, beef broth, salt, and black pepper. Stir well until fully mixed.

5. Pour and Combine

Pour the sauce evenly over the beef and vegetables in the slow cooker, ensuring everything is coated.

6. Slow Cook

Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours until the beef becomes tender and flavorful. This slow cooking process is what makes Keto Pepper Steak so soft and rich.

7. Thicken the Sauce (Optional)

If you prefer a thicker sauce, stir in 1/2 teaspoon xanthan gum during the last 20 minutes of cooking. Mix well to avoid clumps.

8. Finish and Serve

Drizzle 1 teaspoon sesame oil before serving for an extra layer of aroma and depth. Serve warm and enjoy your Keto Pepper Steak at its best.
