Hot Ham & Swiss Croissants are my favorite easy sandwich, perfect for lunch or for dinner!

This is one of my most popular recipes and I know it’s a favorite in our house.

Check out this video to see how to make these delicious Hot Ham & Swiss Sandwiches!


It is such a simple meal and I think that is the appeal.  It is easy enough that anyone can make them and the flavor combo is amazing!

My favorite thing to do is make a big batch of these and wrap them in foil, then keep them in the fridge.  They take minutes to heat up and are a lifesaver on busy nights.  It is so comforting to know I have these hearty sandwiches waiting in the fridge and dinner will be just minutes away.

They are also great to keep in the fridge for fast lunches, filling breakfasts or hearty snacks when they come home from work and school ravenous.

The honey mustard sauce on these really bump up the flavor and take them to the next level. It is sooo good, you can use it on these sandwiches, as a dipping sauce for chicken strips, or even a salad dressing.

The buttery croissant holds all the warm ham and gooey cheese deliciousness.  Everything compliments each other so well making it the ultimate sandwich!

Hot Ham & Swiss Croissants are perfect on a cold winter night, a breezy spring day, a chilly fall evening, and since they require minimal heating up time they are great to make on those scorching summer days when you do not want to be in the hot kitchen.

I’ve also had a lot of people say they love taking these camping because you can make them ahead of time and warm them up at camp.  Love it!

Can I use any cheese?

Any cheese you like will work, just make sure you use a slice on each side for optimal meltiness!

What is the best ham to use?

Any ham you like will work!  I like using honey ham from the deli, but whatever deli ham you have on hand will work.  You can also use leftover ham from the holidays, that would work wonderfully in this recipe!

Can I freeze these?

You sure can!! Assemble the sandwiches and then you can wrap them in foil and pop them into a freezer bag until you are ready to use.  Be sure to thaw them before cooking or just add a little extra cooking time to be sure they are warm and melty all the way through.  Freeze for up to 3 months.

Can these be made with no sauce?

Of course!! I love the sauce and it adds a pop of flavor, but if you aren’t a mustard fan or have picky eaters (I feel you!) then feel free to leave it out, they will still be yummy!

Do I have to wrap these individually?

I get this question a lot.  You guys want to know if you can make all the sandwiches, pop them on a cookie sheet and then wrap the whole thing in foil and bake the next day.  Yes you can do that if you are baking them the next day.  I would not freeze them without being individually wrapped and I would not keep them for a more than a day in the fridge unless they are individually wrapped, they will not stay fresh as long.  If I were to use this method I would wrap the pan in plastic wrap to keep them fresh and then remove it and replace with foil before baking.

Do these travel well?

These travel amazing!!! I have lots of readers that tell me they love making these for camping because they travel so well and are so easy to reheat and can feed a crowd which makes them perfect for taking to parties, pot lucks, camping, traveling and picnics!!!

How to make Hot Ham & Swiss Croissants

  • Just spread a little homemade honey mustard on a split croissant.
  • Add swiss cheese on both sides (you can never have enough cheese!!) Then pile on some thin sliced ham.
  • Sandwich it closed.
  • Wrap in foil.
  • Now you can either put them in the fridge or bake them.
  • I place what I need on a cookie sheet and pop them in a 350 degree oven for about 10-15 minutes.  You just want to warm them up and really melt the cheese.
  • Then voila you have the perfect dinner!  I serve these with a little side salad and it makes for an amazing dinner that is so easy to whip together!


  • Dijon Mustard- This adds a great pop of flavor to these sandwiches but you can use what you have on hand. 
  • Honey-  This adds a little sweetness to the sandwiches.
  • Brown sugar-  Adds a little sweetness and flavor to the sauce. 
  • Croissants-  I like to use the large full size ones but you can use the minis too if your prefer. 
  •  Swiss cheese-  These are hot ham and swiss but if you do not like swiss feel free to use your favorite sliced cheese. 
  • Deli ham-  Any flavor you like and you might not end up using the whole pound, depends on how thick you like your sandwiches.  This is also a great recipe to use up leftover ham. 

Products I used to make this dish!

Honey Dijon Mustard:  I always keep this on hand, it is my favorite to use in recipes like this and amazing on sandwiches and burgers!
Copper Baking Sheet:  I am obsessed with this baking sheet, cooks evenly and everything wipes up soo easily!
Large Wooden Cutting Board: I love using the large space of this cutting board to assemble these sandwiches.

  1. Have you ever tried assembling these and freezing? I don’t see why it wouldn’t work, but curious if you’ve tried it. Thinking these would be the perfect quick meal/snack for the early days with a new baby, when I’m nursing a baby all the time and HUNGRY all the time. :)

    1. I think these are perfect for the freezer. I just had a baby and wish I would have frozen some! Congrats on your new little one!

Loved them!!! Will add turkey next time, but endless possibilities. Just the right amount of sweet and savory. Thank you for something new and yummy!!!!5 stars

  3. These are wonderful because of the sauce you made! I’m going out for more ingredients and I will be making them up to take to an Oscar Night party.

    1. You should be able to wrap them in foil and throw them right on the coals. We do that with potatoes all the time. Just keep an eye on them so they don’t cook too long.

  5. I made the Ham and Swiss sandwiches for camping last weekend. They were a big hit and will definately be on the camping menu again.

  6. Could you make a dozen of these and instead put them on a cookie sheet and put aluminum foil over the cookie sheet instead of individually?

    1. I made these for the first time last week and they are amazing. I didn’t have Dijon mustard so I used yellow mustard and it came out just as good.

  7. Not only is it quick it’s delicious and super easy too! I used leftover baked him which worked out perfectly. Thanks so much for sharing

  10. Girl, that sauce will make you wanna slap someone it’s soooo good!!! It reminds of what Honey Baked Ham puts on their sandwiches! Love love this recipe, it was so quick and easy.

    1. I’ve been making a variation of these sandwiches for over 20 years. The only difference is I use melted butter on the rolls sprinkled with garlic butter; no mustard. I’ve had them made ahead for parties st my house. They are always a hit.

  12. Can I make more and put them on a cookie sheet. Cover the pan with foil and bake them the next morning. I’m making them for a brunch/baby shower.

    1. I think that would be okay, I would maybe wrap in plastic wrap to keep them from drying out overnight since you aren’t wrapping them individually, then the next morning I would take off the plastic wrap and replace with foil before baking.

  13. I understand a ecipe similar to this except it used hamburger buns and a butter and Dijon mustard. Spread they were good. I made them for my residents at a CBRF. I however love crossings so this one is going to be My at home go to.5 stars

  14. Would love to make this for an up coming birthday party/baptism. Was wondering though about putting them in a roaster for a few hours while we leave to go to church and baptism. Would that work to do? Do you have any suggestions on how to make it work. Would be in the roaster for around 3and half hours.5 stars

  15. I made these last week and took them on our camping trip. We kept them in the cooler then heated them daily on a griddle for breakfast . They were delicious and such an easy meal. I’m about to make another batch for the upcoming week. Thank you so much for sharing this recipe!

    1. Did you leave them in the foil when baking them on the griddle? Temp: 350, for 15 min?. This looks like a great camping breakfast!

  16. These are GREAT! I made a batch of these and also turkey. I froze them and in the morning threw them in my lunch bag and by the time lunch rolled around they were perfect heated up for 10 minutes!! Thank You!!5 stars

    1. I do get them right in bakery section of any grocery store. Sams Club and Costco always have a big container of them too.

  17. I’m going camping next weekend and I think these will be perfect for breakfast! Would these work on a portable gas grill? Maybe keep on low and just put the tinfoil directly on the grill?
