Hot Ham and Cheese Croissant Sliders are easy to make for a crowd! Fill butter croissants with ham and cheddar and bake with a buttery mustard and poppy seed sauce.

Thanks to the sponsorship of Walmart, I am bringing you this new twist on a classic slider recipe. It will make you wondering what else you can do with croissants!

I’ll never forget being in Paris with my husband on our second wedding anniversary. We spent four glorious days sightseeing and picnicking and eating all of the best food Paris has to offer. My favorite? Croissants, of course.

Every morning we’d go to the same bakery in the Rue Cler and I’d get a Pan Au Chocolat, otherwise known as a chocolate croissant. My husband loved ordering ham and cheese croissants multiple times a day, for breakfast or lunch. He loves a good ham and cheese sandwich, especially when slathered with mustard.

I was reminded of those croissants a few weeks ago at a potluck. One of the moms brought ham and cheese sliders that had been coated in a mustard and butter sauce. 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 thanked me for my idea!

Sliders are so simple to make. You just need a few ingredients and they feed a crowd.

Oven baked Ham and Cheese Croissant Sliders with garlic, mustard, and poppyseed are the perfect party dish!

You only need a few simple ingredients to make the sliders:

  • Ham
  • Cheese
  • Butter Croissants

Once you have the mini sandwiches assembled, that’s when you create the buttery mustard sauce for over the top. Baking them in the oven melts the cheese and allows the sauce to soak through the croissant, creating a delicious hot sandwich.

When choosing a croissant, you want to choose a good quality one. I’ve had a lot of butter croissants in my lifetime and believe me, not all are created equal. Last time I was at Walmart I saw Marketside All Butter Croissants in the bakery section. I grabbed a box and realized they’re the good kind: genuine all butter with the essence of French baking!

Croissants are such a good substitute for bread or rolls. The rich buttery flavor pairs perfectly with deli meats and cheeses, whatever you choose to dress them up with.

While I was at Walmart I picked up the other ingredients for the sauce:

  • Butter
  • Mustard
  • Minced Onion
  • Poppy Seeds
  • Garlic

The way to make a great slider is to 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.

Tips for making croissant sliders:

  • 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?
