Description

Juicy air fryer chicken breasts topped with sweet roasted onions and melty Fontina cheese — all the flavor of French onion soup in a fast, gluten-free, low-carb dinner.

Ingredients 

For the Onions

  • 1 large onion, thinly sliced
  • 2 tablespoons olive oil
  • 1 teaspoon granulated sugar
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon black pepper

For the Chicken

  • 2 boneless, skinless chicken breasts,
  • 2 teaspoons olive oil
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon black pepper
  • 2 ounces Fontina cheese, sliced

Instructions

  • Slice the onion into thin slices.
  • Toss the onions with olive oil, sugar, salt, and pepper. Spread them in a single layer in the air fryer basket or on the tray. Air fry at 350°F for 5–7 minutes, until soft and golden. (For deeper, jammy onions, roast in 5-minute rounds for 15–20 minutes total, tossing between each.)
  • Rub the chicken breasts with olive oil and season with salt and pepper. Air fry at 350°F for 7–9 minutes, flipping halfway, until cooked through to an internal temperature of 165°F.
  • Top each chicken breast with the roasted onions.
  • Lay the sliced Fontina over the onions and return to the air fryer at 350°F for 1–2 minutes, just until the cheese is melted.
  • Plate, serve, and enjoy.
