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.

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.

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.
