I rarely, if ever, ate Mexican food growing up. Fast forward to my move to Oklahoma…my first week on the job was the Big 12 basketball tournament in OKC, and we ate Mexican food at least three times in a four-day period.

One of my favorite things to order at Mexican restaurants is steak fajitas. If it’s my first visit I always get fajitas; I figure if they can do those well, everything else will be delicious.

I can never get that trademark fajitas sizzle, so I’ve learned to improvise. My Crispy Chicken Fajita Wrap is a great handheld sandwich. When I want to lighten it up I make Grilled Vegetable Fajitas. And when the craving hits for beef fajitas I kick it up with Steak Fajita Quesadillas

  • You get all of the flavors of traditional fajitas, inside of tortillas
  • The ribeye takes these fajitas to incredible new levels
  • They’re easy to make and great as an appetizer or lunch

Step up your game with ribeye! Skirt steak or flank steak are traditional for fajitas, but I tried ribeye once at a restaurant and never looked back.

Ribeye is more tender and flavorful than flank or skirt steak, and you can use thicker chunks of ribeye


I use red onions and red/green bell peppers, but you can substitute yellow onions and your favorite combination of peppers.

Slice the onions and peppers into thin slices so they cook evenly. Start the vegetables over high heat so they get a nice char, and then turn down the heat until they soften.

Don’t skimp on the cheese! That’s what holds your Steak Fajita Quesadillas together. I use Cabot Sharp Cheddar Cheese because I always have it on hand and it melts well. But a Mexican cheese blend also works well.

I normally use Burrito-Sized Tortillas and cut the Steak Fajita Quesadillas into quarters. You could also use smaller tortillas for more individual portions.


I used to always buy fajita seasoning. But once I realized how easy it was to make it myself, I always have some in my pantry. It’s super simple to make, uses spices you likely already have on hand and lasts for weeks in an airtight container.

The recipe makes about 1/2 cup of fajita seasoning. You only need about 3 teaspoons for this recipe, so you’ll have plenty leftover.

In a bowl, combine all of the fajita seasoning ingredients and set aside.

Cut ribeye into 1/2” chunks. Season with the fajita seasoning and set aside.

Heat avocado oil in a large skillet over medium-high heat. Add onions and bell peppers and sauté for 3 minutes, tossing occasionally so the vegetables get charred.

Turn heat to medium, add seasoning, and cook for 7 minutes until softened.

Remove vegetables and set aside. Add a little bit more oil, add steak, and cook for 3 minutes per side.

Return pepper and onion mixture to the skillet, and mix together.

Lightly spray a clean skillet with cooking spray, and lay one tortilla inside. Top tortilla with the steak mixture, leaving a little space around the edges so the filling doesn’t fall out.

Place another tortilla on top. Turn heat to medium, place a flat pot cover or plate on top of the quesadilla, and cook for 3 minutes. Carefully flip the quesadilla over with a large spatula and cook for another 3 minutes.

Transfer Steak Fajita Quesadillas to a cutting board. Carefully cut the quesadillas into quarters with a pizza cutter. Serve immediately

Prep and cook the meat and veggies ahead of time. Make a big batch and store the extras in an airtight container in the fridge for up to 5 days.

Fill the tortillas and finish immediately before serving. If you make them ahead, the tortillas will get soggy and then get hard if you reheat them.


So, it depends. As an appetizer, easily for 4 people. 2 people can share it. And yes, I have eaten the whole thing myself more often than I care to admit. And that’s why it’s an occasional treat.

Make Steak Fajita Quesadillas for a crowd! Double or even triple the filling, use soft taco sized tortillas and let your guests make their own mini quesadillas by finishing them on a flat top or griddle.

If you don't have red onions, yellow onions will work fine
