Air Fryer Croissant and Egg Breakfast Sandwich

An Air Fryer Croissant and Egg Breakfast Sandwich tastes like it's straight from a French patisserie, but you made it yourself without ever leaving home.

The ingredients:

*Please note that the exact measurements along with a "shop the recipe" feature from Instacart and Walmart is available inside the printable recipe card.

Basic ingredient information:

LARGE CROISSANTS - I used croissants that I purchased from Costco. They're large, delicious, and incredibly flaky. Feel free to use your favorite brand of croissants (or even make your own if you're so inclined). *Important note -this recipe is NOT intended for pre-baked crescent rolls that come in the pop tube (you know the ones).

LARGE EGGS - You will need two eggs per sandwich. Room-temperature eggs whisk together easier than cold eggs right out of the fridge. Allow your eggs to sit on the counter at room temperature for 30 minutes, or run them under warm water for 2 minutes to bring them to room temperature quickly.

BUTTER - I always use salted butter, but you can use unsalted butter if that's what you prefer for your eggs. Melt the butter in the microwave (one tablespoon melted butter per sandwich) and allow the melted butter to cool slightly before adding it to the whisked eggs.

MILK - This ingredient is optional, but I like adding a splash of milk to my eggs for additional richness. I used 2% milk, but any variety of milk will work (except sweetened almond or nut milk).

SALT AND PEPPER - Kosher salt and freshly cracked black pepper are always the seasonings I use. If you use iodized table salt for this recipe, please refer to the gray box below.

*Important Note—If using table salt instead of kosher salt, please cut back on the amount of salt called for in the recipe card by half because they measure differently due to grain size.

Necessary kitchen tools and equipment:

• Air Fryer (or conventional oven) - These delicious egg-filled croissant breakfast sandwiches can be made in either an air fryer or oven. They'll cook quicker and crispier in an air fryer, but a conventional oven works too. For the air fryer, you'll need to cook the sandwiches at 350 degrees F (175 degrees C) for approximately 10-12 minutes, and for a conventional oven, you need to preheat the oven to 375 degrees F (190 degrees C) and cook them for approximately 20-22 minutes.
• Serrated Knife - Since croissants are flaky and delicate, a serrated knife works best. Use a light sawing motion with the Knife to gently remove the top ⅓ of the bun.
• Cutting Board
• Mixing Bowls - I like to use small ones as prep bowls with all my add-in ingredients.
• Whisk - A fork will also work for blending eggs, but I love my trusty whisk.
• Chef's Knife - Used for chopping any additional fillings you may use in your sandwich. You can find a list of suggestions and options below, but feel free to devise your own concoction.
• Box Grater - grated cheese works best for these egg sandwiches. Feel free to use pre-shredded cheese from the store, but because it gets coated with an anti-caking agent, it won't melt as nicely as cheese grated from the block.
• Spatula - Used to make removing the egg sandwich from the tray easier before serving.
• Oven gloves - Once you reach for the air fryer baking sheet without one, you'll thank me. As a reminder, this is not a microwave; cooking utensils and equipment get HOT (I speak from experience here)!!
• Glass Measuring Cup - I often use my 4-cup glass Pyrex measuring cup as a bowl. It's microwave-safe, and that little pour spout is handy for many things.
• Parchment Paper - Anytime I can use parchment paper to help make cleanup more manageable, I'm all for it. This is optional, of course, but I recommend using it because sometimes some of the uncooked eggs will escape before fully setting in the sandwich.
• Baking Sheet - Whether cooking these egg-filled croissant sandwiches in the air fryer or oven, you'll need a properly sized baking sheet for whatever appliance you use.
• Kitchen Timer

Additional croissant breakfast sandwich add-in suggestions:

• Pre-cooked bacon, cut into small pieces
• Diced ham, cut into small pieces
• Cooked breakfast sausage, cut into small pieces
• Assorted cheeses, grated or shredded
• Spinach, frozen (thawed and drained) or fresh, chopped into small pieces
• Assorted, finely chopped vegetables
• Pre-cooked and shredded hash browns
• Mushrooms, chopped into small pieces

How many eggs are used per croissant breakfast sandwich?

I wrote the recipe using two large eggs for each sandwich. However, if you'd like to use one or even three eggs (depending on how eggy you'd like), feel free to do so and limit or omit the filling extras.

Can croissant egg sandwiches be cooked in a conventional oven?

They sure can, but be aware that they will take longer to cook at a higher temperature and won't become as deep brown or flaky as when cooked in an air fryer.

What can you serve alongside an egg-stuffed croissant breakfast sandwich?

Fresh fruit of any kind is always a delicious accompaniment to a breakfast sandwich, but so is this tall and refreshing Golden Statue Prosecco Cocktail made with pineapple juice, amaretto, and prosecco.

And for another colorful breakfast accompaniment, why not serve this light and citrusy Avocado and Orange Salad with Orange Poppy Seed Vinaigrette?
