Croissant Grilled Cheese | A cheesy, flaky, buttery spin on the classic grilled cheese. This croissant sandwich is an easy and delicious lunch or snack and takes just a few minutes to make.

Croissants are a light, flaky, buttery pastry, perfect for making sandwiches. When I went to San Fransisco, I had the best croissant sandwich at a little cafe, and since then, croissant sandwiches have been a staple in my house.
This grilled cheese croissant is everything you want in a grilled cheese, just more flaky, buttery and delicious. It’s made in a pan, like classic grilled cheese, so it’s just as simple and easy. It makes for a quick breakfast or lunch if you’re busy, or just craving comfort food.
The croissant gets golden brown and crispy on the outside, and it’s filled with gooey, melty cheese. I always use 2 or 3 cheeses when I make grilled cheese, and it’s really up to you what kind you use. Almost any cheese works, so use whatever you have on hand.
What kind of croissants should I use?
Croissants are a favourite for many people. They’re so popular that they’re likely sold in your local grocery store. Of course, you can buy them from a bakery, or even make them at home, but the process can take an entire day.
I love Costco Butter Croissants! They’re flaky, affordable, and super convenient.
Can you grill croissants?
Yes, you can grill croissants in a frying pan to achieve a crispy, buttery, golden-brown finish. Croissants can be used as bread for grilled cheese. They offer a light, flaky vessel to hold the melty cheese. Grill it up in a frying pan and try it out!

What to serve with croissant sandwiches
Croissant sandwiches are perfect for a quick snack, or part of lunch or dinner. Serve them with a side of Dill Pickle Chickpea Salad for some added protein.
For something more hearty, serve the sandwich with soup, like my Lima Bean Soup or Carrot Lentil Soup.
Storage
The grilled cheese is best served immediately after making, but it can be stored in the fridge for up to 2-3 days.
FAQ’s
You should cook grilled cheese over medium low heat so that the bread can be toasted without getting too dark while the cheese melts.
You can make a grilled cheese croissant the same way you make regular grilled cheese. Butter the outside of the croissant and fill it with cheese. Fry it until it’s golden brown and melty.
