How to Make Easy Keto Pepper Steak
Step 1: Sear the Steak
Heat 1 tablespoon of olive oil in a skillet over medium-high heat. Once hot, add those juicy steak strips seasoned with salt and pepper. Searing them until browned will develop rich flavors that make this dish irresistible!
Step 2: Sauté the Peppers
Remove the cooked steak from the skillet and set aside. In the same pan, lower the heat to medium and add another tablespoon of olive oil. Toss in your sliced bell peppers and sauté until they become tender. This step adds sweetness to balance out the savory elements.
Step 3: Infuse Flavor
Now it’s time to elevate your dish! Add minced garlic and ginger paste to the skillet, sautéing for about 30 seconds until fragrant. This brings warmth and depth to your sauce that you won’t want to miss.
Step 4: Prepare the Sauce
In a separate bowl, mix together soy sauce, Swerve brown sugar substitute, and xanthan gum until smooth. This mixture will create a delightful glaze that clings beautifully to your steak and veggies.
Step 5: Combine Everything
Return both steak and peppers to the skillet. Pour your prepared sauce over everything and toss gently to combine. Let it simmer for several more minutes while stirring—this allows all those beautiful flavors to meld together perfectly.
And there you have it—your very own Easy Keto Pepper Steak ready to be enjoyed! Perfectly tender, utterly delicious, and incredibly easy—this dish is sure to become a staple at your dinner table!
Pro Tips for Making Easy Keto Pepper Steak

-
Choose the right cut of meat: Using top sirloin provides a good balance of tenderness and flavor, making it ideal for quick cooking and a delicious meal.

-
Adjust the seasoning: Taste as you go! Depending on your preferences, you might want to adjust the soy sauce or add more spices to enhance the flavor profile.
-
Use fresh ingredients: Fresh garlic and ginger provide vibrant flavors that elevate your dish. Fresh produce can make all the difference in taste!
