Nothing beats a warm ham and cheese croissant sandwich when you crave something comforting but quick. Flaky golden croissants, savory ham, gooey Swiss cheese, and a zippy homemade honey mustard sauce all come together for an irresistible meal perfect for brunch lunch or an elevated snack.
I first whipped these up on a lazy Sunday and now everyone at home wants them on repeat. The easy garlic butter trick takes these to a whole new level.
Ingredients
- Croissants: Fresh bakery croissants give the best flaky texture Choose ones that feel light not dense and have a golden crisp outside
- Deli ham: Go for good quality deli ham sliced thin Honey or black forest work beautifully for flavor balance
- Swiss cheese: This melts perfectly with just the right tang Check the cheese counter for real Swiss or try Gruyere
- Honey mustard sauce: Adds sweetness and zing Homemade or a good bottled version both work
- Butter: Unsalted butter is best for making the garlic spread rich
- Garlic powder: Lends a cozy flavor without raw garlic sharpness Look for aromatic powder not bland or stale
- Italian seasoning: A touch of dried herbs elevates the butter and pairs well with the savory ham
Step-by-Step Instructions
- Preheat the Oven:
- Set your oven to three seventy five degrees Fahrenheit Line a baking sheet with parchment paper so the sandwiches are easy to remove and clean up is a breeze
- Prepare the Croissants:
- Carefully cut each croissant in half horizontally using a sharp bread knife You want to create a clean sandwich base so filling does not spill out
- Spread the Sauce:
- Lay the bottom halves on the prepared baking sheet Spoon a good layer of honey mustard on each base leaving a little for the tops This makes every bite flavorful
- Layer the Fillings:
- Place a slice of Swiss cheese on each sauced croissant bottom Follow with two slices of ham then finish with another cheese slice The double cheese makes them extra melty
- Assemble the Sandwiches:
- Spread more honey mustard on the top croissant halves then close the sandwiches Press down gently so everything stays tucked inside
- Make the Garlic Butter:
- Melt butter in a small bowl Stir in garlic powder and Italian seasoning Mix until smooth and fragrant
- Brush and Bake:
- Use a pastry brush to coat the tops and sides of each sandwich with garlic butter Bake for twelve to fourteen minutes until croissants are deeply golden and cheese is bubbling out
- Serve Warm:
- Serve these fresh from the oven with extra honey mustard if desired

A hint of garlic butter on top brings out the bakery aroma and makes them feel fancy My kids love helping with the butter brushing and these croissants always remind me of our Saturday movie lunch tradition
Storage Tips
Store leftovers in an airtight container once completely cooled Reheat in the oven at three fifty degrees for about eight minutes to revive the flakiness The microwave works but can make croissants slightly softer

Absolutely! While Swiss cheese melts beautifully, feel free to substitute with provolone, cheddar, or mozzarella for different flavors.

They’re best enjoyed warm right after baking, when the croissants are crisp and the cheese is melted, but they also taste great at room temperature.

You can assemble the sandwiches in advance and refrigerate them. Bake just before serving for the best texture and flavor.
- → What’s a good side to serve with these sandwiches?
Pair with a fresh green salad, fruit, or some roasted vegetables to round out the meal.

Homemade sauce enhances the flavor, but store-bought honey mustard works well if you’re short on time.
