Ingredient Breakdown

Here’s what you’ll need to make this scrumptious sandwich:

4 Whole Croissants
4 Slices Swiss or Cheddar Cheese
8 Slices Deli Ham or Turkey
4 Leaves Lettuce
1 Medium Tomato
2 tbsp Dijon Mustard
2 tbsp Mayonnaise

Let’s Get Cooking!

Here’s how to whip up this crafty croissant sandwich that’s perfect for a busy weeknight!

Warm the croissants: Preheat your oven to 350°F (about 180° for my Celsius friends). Place the croissants on a baking sheet and warm them for about 5 minutes until they’re just slightly toasted and their buttery aroma fills your kitchen, so heavenly!
Slice carefully: Now, take those warm croissants and slice them in half, lengthwise. Do this gently so that the flaky layers don’t tear apart. Nobody wants a messy sandwich, right?
Spread the condiments: On each cut side of the croissants, spread a couple pinches of Dijon mustard and mayonnaise evenly. Make it yours! Sometimes, I sprinkle in a few herbs or hot sauce for an extra kick.
Add the cheese: Layer your cheese slices right against the cut sides of the croissant. This little step prevents sogginess from any toppings. After all, we want that nice, crispy bite!
Stack it up: Build your sandwich by layering on the ham (or turkey), followed by that delightful crisp lettuce and tomato slices. Make sure everything is nice and balanced in flavor and texture!
Close it gently: Bring the two halves of the croissant together, and oh, I highly recommend cutting the sandwich diagonally. It just makes it feel a little fancier, don’t you think?
Serve immediately: That’s it! Best enjoyed fresh with a side of potato chips or a simple salad.

Customizable

One of the secrets to a delicious croissant sandwich is how customizable it is. You can easily switch out ingredients based on allergies or what’s lurking in your fridge. Leftover grilled veggies? Toss those in!

Comfort Food

It’s loaded with tons of flavor… and let’s be real, it just feels good to eat. There’s something about the rich buttery croissants combined with savory meats and creamy cheeses that hits the spot!

Serving and Storage Tips

How to Serve This Croissant Sandwich

Serve these sandwiches while hot! They’re fantastic as they are or with a side of homemade potato chips, just saying! For a lighter approach, a crunchy green salad works great, too.

Storage

If you have any leftovers (which is rarely the case in my house!), you can keep them in the refrigerator for about 1-2 days. But, I wouldn’t recommend assembling the sandwiches ahead of time, as the croissants can get soggy. Instead, keep the ingredients separate and assemble as you go!

Reheating Instructions

To reheat, pop your sandwiches back into a 350°F oven for about 5 minutes until warmed through and cheesy. If I’m feeling lazy, I sometimes microwave them, but they lose that crispiness, just a little heads-up!

Freezer Friendly

Now, here’s the thing: this croissant sandwich is not really freezer-friendly. Croissants lose their amazing texture after freezing and thawing, which is a bit of a bummer. But hey, feel free to freeze your deli meats or cheeses for future use!

And there you have it! This croissant sandwich recipe is full of buttery goodness and versatility that will surely become a staple in your weeknight dinner rotation. Just remember that cooking is supposed to be enjoyable, so have fun getting creative with your ingredients! Happy cooking! For more Recipes Follow Us in our Pinterest.
