Quick and Easy Keto Chili Lime Steak Fajita

12 ratings

If you are looking for a quick and easy recipe for your busy weeknights, then you should end your search here. This Keto steak fajita recipe is tangy, juicy, and slightly spicy. It requires 10 minutes of active prep time and another 10 minutes of cooking. You can prepare all the elements the night before and have dinner ready in no time.

The steak is taken to the next level by marinating it in chili powder, minced garlic, lime juice, cumin powder, and olive oil. You can let it marinate for as little as 30 minutes, or ideally, overnight. This leaves the steak juicy, tender, and highly flavorful.

Most Keto steak fajitas are cooked on the pan or grill, while this recipe uses an unconventional method. The foil pack method is an easy, fast, and fuss-free way for cooking Keto fajitas. First, you must preheat your oven to the highest setting, at least 425 Fahrenheit. Then, you must portion out the seasoned vegetables into the center of two 12”x12” pieces of foil, and top them with the marinated steak. Tightly wrap the foil around the steak and vegetables and bake for 6-8 minutes, depending on how you like your steak.

What can you serve this fajita with?

Some tasty toppings include sliced avocado, guacamole, sour cream, fresh herbs, and lemon/lime juice. All these options complement the steak fajita flavors and add freshness. For sides, you can serve this dish with cauliflower rice, steamed broccoli, or Keto tortillas.

Are fajitas Keto?

Not all fajita recipes are Keto-friendly, but this one is. This chili lime steak fajita contains only 4g of net carbs per serving but carries tons of flavor. The quantities of the onions and peppers used are enough to shine through without sabotaging your daily carb allowance.

    The protein seems way too high for what you are eating here - where is that coming from besides the 4 or so oz of cooked steak?

      Hi, I'm thinking it's from the peppers and the avocado.
