Creating your Air Fryer Ham and Cheese Sliders is a breeze. Just follow these simple steps:

1. Preheat the Air Fryer: Preheat your air fryer to 350°F (175°C).
2. Prepare the Buns: Slice the slider buns in half, keeping the tops and bottoms together.
3. Assemble the Sliders: Place a slice of ham on the bottom half of each bun, followed by a slice of cheese. Close the buns with the tops.
4. Make the Butter Mixture: In a small bowl, combine melted butter, garlic powder, onion powder, and Dijon mustard if using. Mix well.
5. Brush the Sliders: Brush the butter mixture generously over the tops of the assembled sliders.
6. Add Poppy Seeds: If desired, sprinkle poppy seeds on top for added flavor and texture.
7. Air Fry: Place the sliders in the air fryer basket in a single layer. Cook for 10-12 minutes or until the tops are golden brown and the cheese is melted.
8. Check for Doneness: Ensure the sliders are heated through and the cheese is fully melted.
9. Serve: Remove the sliders from the air fryer and let them cool for a minute before serving.

These steps will guide you effortlessly in creating these incredible sliders that everyone will love.
