Ingredients
See the recipe card for exact amounts.
- croissants: Use large croissants for this recipe.
- pesto: I used a store-bought basil pesto for this recipe but homemade oregano pesto or pepita pesto would be good too!
- mayo: any mayo is fine
- cheese: I like Havarti for its mild flavor and ability to melt.
- toppings: Shredded romaine lettuce adds freshness and pickled red onions add some much-needed acidity and tanginess to cut through the super savory and rich flavors in this sandwich.
Substitutions
- pesto: try red pesto, made with sundried tomatoes!
- cheese: try cheddar cheese, Swiss cheese, Gruyere, or Monterrey Jack.
- toppings: choose other toppings like tomato, cucumber, or other mixed greens.
Instructions
Prep Tips
Cut the croissant in half.
- Mix the mayo and pesto together in a small bowl.
- Spread the pesto mayo on the four cut sides of the croissant.
- Layer the cheese on one side of each croissant.
- Place the croissants on an air fryer tray or the air fryer basket.
Air fry for 2-4 minutes.
I use a tray style air fryer and air fry my croissant for 2 minutes and then rotate the top and bottom trays before air frying for another minute.
This crisps the croissant and also melts the cheese.
- Place the finished croissant on a plate or croissant. Add freshly cracked black pepper on the cheese side.
- Add shredded lettuce and pickled red onions.
Place the top side of the croissant on top of the lettuce to make the sandwich.
