What Kind of Croissant Should I Use?

For best results, go for large, buttery croissants that are light and flaky. Day-old croissants work great because they hold up well to fillings and toast nicely. If you’re buying from the store, look for ones with a slightly crisp exterior and soft, pillowy inside — the better the croissant, the more decadent your sandwich will be.

How To Make the Breakfast Croissant Sandwiches

Step 1: Prepare the Croissants

Slice each croissant in half horizontally. If they’re a bit soft, you can toast them lightly in a skillet or oven for a bit of crunch.

Step 2: Cook the Bacon

In a skillet over medium heat, cook bacon strips until crispy. Transfer to a paper towel-lined plate to drain excess grease.

Step 3: Cook the Eggs

In the same skillet, fry or scramble your eggs to your preferred doneness. Season with salt and pepper to taste.

Step 4: Assemble the Sandwich

Place a layer of greens on the bottom half of each croissant. Top with an egg, a couple strips of bacon, and your cheese of choice. Place the top half of the croissant on and gently press.

Step 5: Optional Melt

For extra melty cheese, place the assembled sandwiches in a warm oven (about 350°F) for 5 minutes until cheese melts.

How to Serve and Store These Breakfast Croissant Sandwiches

These breakfast croissant sandwiches are best served warm, right after assembly, when the cheese is melty and the croissant is toasty. However, they’re also great for meal prep. You can store assembled sandwiches (without greens) wrapped in foil or an airtight container in the fridge for up to 3 days.

To reheat, place them in the oven or toaster oven at 350°F for 10–12 minutes or until warmed through. They can also be frozen for up to one month — just thaw overnight before reheating.

This recipe makes 4 hearty sandwiches, perfect for feeding a family or for storing and enjoying throughout the week.

Frequently Asked Questions

Can I make these croissant sandwiches ahead of time?
Yes! You can assemble them without the greens and store them in the fridge or freezer. Add the greens after reheating to keep them fresh.

What’s the best way to reheat them?
For the best texture, reheat in a preheated oven at 350°F for about 10 minutes. If you’re in a rush, a microwave works, but the croissant may lose some crispiness.

Can I make them vegetarian?
Absolutely. Omit the bacon or swap it for plant-based alternatives, grilled mushrooms, or avocado.

What cheeses work best?
Sharp cheddar, gouda, Swiss, or even brie — use what you love! Melty cheeses with strong flavor make the sandwich even more delicious.
