Here is my favorite croissant grilled cheese recipe, with buttery, flaky croissants instead of regular bread, two types of melty cheese, and a hint of garlic powder for extra flavor.
This grilled cheese is what I make when I want something special but don’t have a lot of time. The croissants get so crispy on the outside while the cheese gets all gooey inside. My kids request this for lunch at least once a week!
Why You’ll Love This Croissant Grilled Cheese
- Ready in minutes – This croissant grilled cheese comes together in just 10-20 minutes, making it perfect for a quick lunch or easy weeknight dinner when you’re short on time.
- Minimal ingredients – You only need four simple ingredients that you might already have in your kitchen to make this satisfying meal.
- Buttery, flaky texture – Using croissants instead of regular bread takes your grilled cheese to the next level with layers of buttery goodness that get perfectly crispy on the outside.
- Double cheese blend – The combination of mozzarella and cheddar gives you the best of both worlds – stretchy, melty goodness with sharp, rich flavor in every bite.
What Kind of Cheese Should I Use?
The beauty of a croissant grilled cheese is that you can really use any cheese you like, though the combination of mozzarella and cheddar gives you the best of both worlds. Mozzarella provides that amazing stretchy, gooey pull when you bite into your sandwich, while cheddar adds a sharp, tangy flavor that keeps things interesting. If you want to switch things up, gruyere, fontina, or even a bit of brie would work wonderfully here. Just make sure to use good quality cheese that melts well, and if you’re buying pre-shredded cheese, know that it won’t melt quite as smoothly as cheese you shred yourself from a block.
Options for Substitutions
This simple recipe is easy to customize based on what you have in your kitchen:
- Croissants: While croissants give this sandwich its special flaky texture, you can use brioche buns or thick slices of sourdough bread if that’s what you have. The sandwich will taste different but still delicious.
- Mozzarella and cheddar: Feel free to mix and match your favorite cheeses here. Gruyere, fontina, provolone, or gouda all melt nicely. You can also use just one type of cheese instead of two – about 100 grams total should do the trick.
- Butter: If you’re out of butter, mayonnaise works surprisingly well for grilling. Just spread a thin layer on the outside of the croissant – it’ll get golden and crispy just like butter does.
Watch Out for These Mistakes While Cooking
The biggest mistake when making croissant grilled cheese is using heat that’s too high, which will burn the buttery, flaky exterior before the cheese has a chance to melt inside.
Medium-low heat is your friend here – it might take a few extra minutes, but you’ll get that perfect golden-brown crust with gooey, melted cheese instead of a burnt outside with cold cheese in the middle.
Another common error is skipping the step of letting your cheese come to room temperature first, as cold cheese straight from the fridge takes much longer to melt and can lead to overcooked croissants.
If you want to speed things up without cranking the heat, try covering the pan with a lid for the last minute or two, which traps the heat and helps the cheese melt faster while keeping your croissants perfectly crispy.
What to Serve With Croissant Grilled Cheese?
A croissant grilled cheese is rich and buttery, so I like pairing it with something fresh to balance things out. A simple arugula salad with lemon vinaigrette cuts through all that cheesy goodness perfectly, or you could go with sliced tomatoes and cucumbers drizzled with olive oil. If you want to make it a heartier meal, a bowl of tomato soup is always a winner for dipping. You could also serve it alongside some crispy pickle spears or a handful of kettle-cooked chips for a nice crunch.
Storage Instructions
Best Fresh: Honestly, croissant grilled cheese is one of those things that’s best enjoyed right away while the cheese is still melty and the croissant is crispy. If you do have leftovers, wrap them in foil and keep in the fridge for up to 2 days, but they won’t be quite as good as fresh.
Reheat: To bring your grilled cheese back to life, skip the microwave since it’ll make the croissant soggy. Instead, pop it in a 350°F oven for about 8-10 minutes, or warm it up in a skillet over medium-low heat for a few minutes on each side until the cheese melts again and the outside gets crispy.

- Calories: 590-670
- Protein: 18-22 g
- Fat: 38-46 g
- Carbohydrates: 40-50 g
Ingredients
- 2 croissants
- 2 oz mozzarella (freshly shredded for a better melt)
- 2 oz cheddar (I prefer Tillamook sharp cheddar)
- 1.5 tbsp butter (I like Kerrygold salted butter for this)
- 1/4 tsp garlic powder
Step 1: Prepare the Croissants and Cheese
- 2 croissants
- 2 oz mozzarella
- 2 oz cheddar
Slice your croissants in half horizontally, creating top and bottom pieces.
Shred the mozzarella and cheddar cheeses if not already shredded—freshly shredded cheese melts much more evenly than pre-packaged varieties.
I find that a box grater works perfectly for this task and takes just a minute.
Step 2: Assemble and Butter the Sandwich
- 1.5 tbsp butter
- 1/4 tsp garlic powder
- cheese-filled croissants from Step 1
Divide the shredded cheese between the bottom halves of both croissants, distributing it evenly.
Close the sandwiches by placing the top halves over the cheese.
Spread about three-quarters of the butter on the outside of the top croissant halves, and the remaining butter on the outside of the bottom halves.
Sprinkle the garlic powder evenly over the buttered exterior of both sandwiches—this adds a subtle savory depth without overpowering the delicate croissant.
Step 3: Cook and Flip the Grilled Cheese
- buttered and assembled croissants from Step 2
Heat a skillet or griddle over medium-low heat.
Once the pan is warm, carefully place both buttered croissants onto the surface.
Cook for 3-4 minutes without moving them until the bottom is deeply golden and crispy.
Flip gently and cook for another 2-3 minutes until the second side is equally golden and the cheese inside is completely melted.
I like to press down gently with a spatula during the last minute of cooking to help compress the sandwich slightly and ensure the cheese melts evenly.
Step 4: Serve Immediately
Transfer the grilled cheese croissants to a plate and let them cool for just 1-2 minutes before serving.
The croissants will continue to crisp slightly as they cool, and this brief rest prevents the molten cheese from burning your mouth.
