Easy Sliders with Croissants

I love croissants and recently I had ham and cheese sliders at a potluck. Everyone loved them and I knew I wanted to recreate them. After all, sliders are always a huge hit. I make them for almost every party but I’ve never tried a ham and cheese until now.

Normally, you see sliders made with dinner rolls, but I decided to switch it up. Why not take the classic ham and cheese slider and use a croissant? EVERYONE who tried these loved them!

ingredients to make ham and cheese croissant sliders

Ingredients in Croissant Sliders

  • Ham
  • Cheese
  • Butter Croissants
  • Butter
  • Mustard
  • Minced Onion
  • Poppy Seeds
  • Garlic

How to make Ham and Cheese Sliders

  • First assemble the mini ham and cheese sandwiches by slicing the croissants and filling them with deli ham and cheddar cheese slices.
  • Once you have the mini sandwiches assembled, that’s when you create the buttery mustard sauce for over the top. Melt the butter and mix the other sauce ingredients into it. Then you pour it all over the prepared sandwiches in the pan, ensuring that flavor in every bite.
  • Bake them in the oven to melt the cheese and allow the sauce to soak through the croissant, creating a delicious hot sandwich.

Croissant Sliders Tips

  • Use any kind of deli meat and/or cheese you like to change up the flavors.
  • Cheddar melts best if it’s a thin slice. I like buying the package sliced cheese for this; it’ll melt better.
  • If you’re a mustard or mayo lover, add some to the croissants when adding the meat.
  • You can make these sliders without poppy seeds if you prefer.
  • Use your favorite kind of mustard (yellow or dijon are great choices) for the sauce.
  • Salt the sauce to taste, especially if you substitute salted butter.
  • Make ahead: make the sandwiches up to a day ahead but add the sauce right before baking.

  1. Wow! These were amazing! I didn’t have poppy seeds, so I sprinkled them with some parsley, garlic powder, and basil. So easy to make with the mini-croissants. They are definitely going on my brunch menu.

  2. Ooooh, I see a Turkey/Cranberry/Brie version come fall! This looks easy and delicious. Would you suggest toasting the croissants before, or do you think it would not matter much?
