Mexican food is my all time favorite food! Gimme allllll the queso, salsa, and guac you got! I’ve truly never met a taco I didn’t like. That’s why I made these keto sheet pan fajitas. I’m just trying to do my part and spread that taco love, y’all. It comes as no surprise that we eat tacos all the time in our house.

Normally I fix my low-carb beef tacos or chicken tacos but there are times when I’m more in a fajita mood.

I love the combination of spices, peppers, and meat in fajitas.

What To Serve With Your Fajitas

If you want to serve these with tortillas, I have the recipe for you. Try Keto Tortillas (1.9 grams of Net Carbs – Vegan & Gluten Free). I then serve these fajitas on top of a bed of Mexican Cauliflower Rice and then drizzle some queso and hot sauce on top. You can also add some of my Low-Carb Chipotle Lime Mexican Coleslaw. Might I also suggest my Keto Tortilla Chips (Low Carb & Gluten Free) — it makes for a nice side. Oh, and you can’t forget about the guacamole or avocado! If low-carb tortillas are your thing, you could make fajita quesadillas, enchiladas, or even burritos.

FAQs

Can I make this using a skillet?

Yes, fajitas are typically fried in a cast-iron skillet, which gives them those nice crispy edges. I made these keto fajitas on a sheet pan in my oven because some days I just don’t have it in me to stand over a stove. You could definitely make these keto fajitas in a skillet if you feel up to it, though!

How do you prevent everything from getting soggy?

You’ll want to put the meat and peppers on a rack on your sheet pan so that the juice and fat can drip down.

I like a really crispy fajita. Suggestions?

Me too! So I throw these under the broiler after they’re finished cooking.

Which hot sauce do you use?

I use Cholula. A popular one, so you shouldn’t have any issues finding it.

How To Store Sheet-Pan Fajitas

Let them cool completely. Put the fajitas in a resealable bag or an airtight container then into the fridge it goes where it can be kept for up to 4 days. You can also freeze the fajitas for up to 3 months. When it comes time to eat them, you can either microwave them or put them in the oven at 350°F. To combat the chicken drying out while reheating them, add either a sprinkle of water or oil.
