Instructions

Step 1: Marinate the Chicken

In a bowl, combine:

Chicken

Olive oil

Chili powder

Smoked paprika

Garlic powder

Onion powder

Cumin

Oregano

Salt

Black pepper

Lime juice

Mix well and let marinate for 15 minutes.

Step 2: Cook the Chicken

Heat 1 tablespoon of olive oil in a skillet over medium-high heat.

Cook the chicken for 6–8 minutes, stirring occasionally, until browned and fully cooked.

Transfer to a plate.

Step 3: Sauté the Vegetables

In the same skillet, cook the sliced bell peppers and onion for 4–5 minutes until tender but still slightly crisp.

Return the cooked chicken to the skillet and toss everything together.

Step 4: Assemble the Sliders

Without separating the buns, slice the entire pack of slider buns horizontally.

Place the bottom half on a clean surface or in an air fryer-safe baking pan.

Spread a thin layer of cream cheese over the buns, if using.

Add half of the mozzarella cheese.

Evenly spread the chicken and vegetable mixture over the cheese.

Top with the cheddar cheese and the remaining mozzarella.

Place the top buns over the filling.

Step 5: Brush with Garlic Butter

Mix together:

Melted butter

Garlic

Dried parsley

Onion powder

Paprika

Brush generously over the tops of the slider buns.

Step 6: Air Fry

Preheat the air fryer to:

350°F (175°C)

Place the assembled sliders in an air fryer-safe baking dish or on parchment paper.

Air fry for 6–8 minutes, or until:

The cheese is completely melted

The buns are golden brown

The tops are lightly crispy

If the buns brown too quickly, loosely cover them with foil.

Step 7: Serve

Remove the sliders from the air fryer.

Let them cool for 2 minutes.

Slice into individual sliders.

Serve with:

Salsa

Sour cream

Guacamole

Chipotle mayo

Ranch dressing

Tips for the Best Chicken Fajita Sliders

Marinate the chicken for extra flavor.

Use freshly shredded cheese for the best melt.

Don’t overcook the peppers—they should remain slightly crisp.

Brush the buns generously with garlic butter for a golden finish.

Air fry in a single layer for even cooking.

Let the sliders rest for a couple of minutes before slicing to keep the filling in place.
