Air Fryer Croissant Sandwiches were my attempt to recreate that bakery-style breakfast at home without overbaking the croissants. The first time, I set the temperature too high and the tops browned before the cheese melted. After testing this three ways, I discovered that 350°F was the sweet spot. That temperature warmed the center, melted the cheese perfectly, and kept the croissant flaky instead of dry. Now this is my go-to brunch shortcut when I want something indulgent but quick.
Why This Air Fryer Croissant Sandwiches Recipe Works
Air Fryer Croissant Sandwiches work because the moderate heat melts the cheese and warms the filling without over-crisping the delicate pastry. Croissants brown faster than regular sandwich bread, so keeping the air fryer at 350°F (175°C) prevents burnt edges.
After testing 370°F, I noticed the tops darkened too quickly while the inside stayed cool. Lowering the temperature gave even heat throughout. Cooking the egg separately in a small mold ensures it sets properly at 160°F (71°C) before assembling, creating a perfectly layered sandwich every time.

How to Make Croissant Sandwiches in the Air Fryer

- Lightly grease two small ramekins or silicone molds.
- Whisk eggs, milk, salt, and pepper until fully combined.
- Pour egg mixture into molds and air fry at 350°F (175°C) for 3–4 minutes, until set and reaching 160°F (71°C) internally.
- Remove eggs and let them rest for 1 minute to firm slightly.
- Lightly butter croissant interiors if desired.
- Assemble sandwiches: bottom croissant half, egg round, cooked meat, cheese slice, and top half.
- Place assembled sandwiches in the air fryer basket.
- Air fry at 350°F (175°C) for 3–4 minutes, until cheese is fully melted and croissant is lightly crisp on the outside.
- Serve warm.
Tips for Perfect Air Fryer Croissant Sandwiches
- Keep temperature at 350°F: Higher heat browns croissants too quickly.
- Use fully cooked meat: Raw sausage won’t cook through properly.
- Wrap loosely in foil: For a softer, less crisp texture.
- Don’t overcrowd: Airflow ensures even warming.
- Check at 6 minutes total: Smaller air fryers may cook faster.
- Let egg rest before stacking: Prevents sliding layers.
Storing and Reheating Croissant Sandwiches
Storage: Wrap tightly in parchment paper and refrigerate up to 3 days.
Freezing: Wrap individually and freeze up to 1 month for best texture.
Reheating (Refrigerated): Air fry at 330°F (165°C) for 3–4 minutes.
Reheating (Frozen): Air fry at 330°F (165°C) for 6–8 minutes, checking halfway.
Variations:
- Ham & Swiss: Skip egg for a quick melt sandwich.
- Veggie: Spinach, feta, and tomato.
- Sweet version: Nutella and sliced strawberries (no egg).
- Turkey & provolone: Add Dijon mustard before heating.
Conclusion
These Air Fryer Croissant Sandwiches are my shortcut to flaky, melty breakfast sandwiches without the bakery price tag. Once I locked in 350°F, the texture was consistently warm inside and lightly crisp outside. They’re simple, satisfying, and perfect for busy mornings.
