Ingredients
- 6 regular croissants
- 12 oz deli ham, sliced
- 12 slices Swiss cheese
- ½ cup honey mustard sauce
- 2 tbsp butter, melted
- ½ tsp garlic powder
- ¼ tsp Italian seasoning
Instructions
- Preheat your oven to 375°F and line a baking sheet with parchment paper. These warm, melty croissant sandwiches are going to be incredible!
- Carefully slice each croissant in half horizontally to create top and bottom pieces. Try to keep them as even as possible for the best sandwich shape.
- Place the bottom halves of the croissants on your prepared baking sheet. Spread each bottom with honey mustard sauce, but save some for the tops too.
- On each croissant bottom, layer one slice of Swiss cheese, then about 2 oz of deli ham (roughly 2 slices), and top with another slice of cheese. This double cheese layer ensures maximum meltiness!
- Spread more honey mustard sauce on the inside of each croissant top, then place them over the filled bottoms to create 6 complete sandwiches.
- In a small bowl, mix together the melted butter, garlic powder, and Italian seasoning. This aromatic topping is what makes these sandwiches extra special.
- Using a pastry brush, generously brush the garlic butter mixture over the tops of all the sandwiches. Bake for 12-14 minutes until the croissants are golden brown and the cheese is completely melted.
- Remove from the oven and let cool for just a minute or two. Serve warm with extra honey mustard sauce on the side for dipping. These are absolutely delicious!
Tips & Variations
- Cheese Options – Try Gruyère, cheddar, or Havarti for different flavor profiles
- Meat Variations – Substitute turkey, prosciutto, or roast beef for the ham
- Add Vegetables – Layer in thinly sliced tomatoes, baby spinach, or arugula after baking
- Make it Breakfast – Add a fried egg for a decadent breakfast sandwich
- Vegetarian Option – Skip the meat and double up on cheese with sliced avocado
- Extra Crunch – Brush the tops with melted butter before baking for an even more golden finish
Serving Suggestions
These Ham and Cheese Croissant Sandwiches pair beautifully with a simple green salad dressed with a light vinaigrette to balance the richness. For brunch, serve alongside fresh fruit and a mimosa for an elegant spread that will impress guests.
If serving for dinner, consider adding a cup of tomato soup on the side for a comforting meal that elevates the classic grilled cheese and soup combination to new heights.
Notes
- Day-old croissants work perfectly for this recipe as they hold up better during baking.
- For make-ahead preparation, assemble the sandwiches, wrap individually in foil, and refrigerate for up to 24 hours before baking.
- The sandwiches are done when the cheese is completely melted and the edges of the croissants turn golden brown.
- Leftover sandwiches can be stored in the refrigerator for up to 2 days and reheated in a 300°F oven for 5-7 minutes.
FAQs
Can I make these sandwiches in an air fryer?
Yes! Air fry at 320°F for about 4-5 minutes until the cheese melts and the croissants are crispy.
How do I keep my croissants from getting soggy?
Avoid adding any wet ingredients like tomatoes before baking, and make sure any condiments are spread in a thin layer.
Can I freeze these sandwiches?
You can freeze the assembled but unbaked sandwiches for up to 1 month. Thaw in the refrigerator overnight before baking.
What’s the best way to reheat leftovers?
For the best texture, reheat in a 300°F oven for 5-7 minutes. Avoid microwaving as it can make the croissants chewy.
