Grab the cheese grater

To get the best melty cheese experience, always shred your own quality cheese instead of using pre-shredded. This small step makes a big difference in how well the cheese melts, giving you that perfect cheesy goodness of quesadillas.

Now that you know what to get from the grocery store, let’s dive into the best part: grilling and eating! Either skip to the recipe card or let me walk you through the easy steps. 

How to Make a Grilled Chicken Fajita Quesadilla

Let’s get started! First, prep your chicken thighs by rubbing them down with a bit of vegetable oil and our savory seasonings.

FYR Red adds a kick os spice to the grilled chicken.

Fire up your grill to medium-high heat, around 350 degrees F. Toss your chicken onto the grill, cooking it for about 7-9 minutes per side until you’ve got tender chicken with a beautiful char. Baste the chicken with some FYR RED Hot Sauce for a fiery kick. Once done, let the chicken rest before chopping it into small, bite-sized cubes.

The fajita mixture of veggies is prepared and grilled.

Now, grab your large skillet or nonstick skillet, add a little canola oil (or a little olive oil), and sauté those fajita vegetables—bell peppers, onions, and jalapenos—until they’re soft and full of flavor. This should take about 4-5 minutes. Once done, clean the skillet and prepare for the main event.

Lay down a large flour tortilla on the skillet, spreading out a cup of cheese on one half of the tortilla. Pile on your cooked chicken, a handful of sautéed fajita veggies, and then another layer of cheese.

The chopped chicken is layered over the flour tortilla on the grill.

Fold the empty side of the tortilla over to seal in all that goodness. Cook for 2-3 minutes on each side, flipping until you’ve got a crispy tortilla and melted cheese.

All that’s left to do is slice the quesadillas into sharable portions and enjoy the flavor fiesta!

What to Serve with Grilled Chicken Fajita Quesadillas

Serve these quesadillas with a side of sour cream, guacamole, and then maybe even some fresh pico de gallo. If you’re feeling extra hungry, pair them with black beans or refried beans for a complete Tex-Mex meal. For a little extra flavor, squeeze some lime juice over the top before serving.

The meal is ready to serve and eat!

Leftovers & Reheating

Got leftovers? No problem! Store them in an airtight container in the fridge. When you’re ready to reheat, just pop them back in a skillet over medium heat to keep that tortilla crispy and the cheese melty. Skip the microwave if you want to avoid a soggy tortilla.

FAQs for Grilled Chicken Fajita Quesadillas

Can I use a different cheese?

Absolutely! While Monterey Jack is a great choice for melty cheese, you can also use cheddar cheese or pepper jack cheese for extra flavor.

Can I make these quesadillas ahead of time?

Yes! You can prepare the fajita mixture and cooked chicken in advance, store it in a small bowl in the fridge, and assemble the quesadillas when you’re ready to eat.

Can I use corn tortillas instead of flour?

Definitely! Corn tortillas offer a slightly different texture but are just as delicious, especially if you like a more traditional flavor.
