Layers of croissant dough wrapped around melty cheese and salty ham turns everyday stuff into something totally next-level. You'll end up with crispy outsides, soft insides, and a sweet buttery crunch in every bite. A simple hit of butter on top and maybe a few herbs for good measure, and now you've got something that works any time of day—breakfast, lunch, or whenever hunger hits.
When my sister and her crew dropped by last weekend, I whipped up these croissants for brunch. Honestly, the smell alone—cheese bubbling, buttery pastry browning—had everyone hanging out in the kitchen before I even got a word out. My nephew, champion of eating fast, actually slowed down to really enjoy each bite. If that's not winning over a teenager, I don't know what is.
Tasty Ingredients
- Big Croissants: Flaky and buttery, they're what make this shine. Bakery ones have great texture, but supermarket croissants do the trick too.
- Good Ham: Gives that salty punch and texture. Sliced deli ham with some marbling? Perfect for flavor.
- Cheese Slices: Melts into that drool-worthy goo. Swiss is classic with a little sweetness, cheddar gets you a nice sharp bite.
- Dijon Mustard: Brings just a little zing. It doesn't take much to perk up the whole thing without taking over.
- Butter, Melted: Swiping this on top gets you a shiny, golden finish that screams "fresh from the bakery."
- Dried Thyme: Totally optional but gives a smidge of herby aroma that vibes with the filling.
- Garlic Powder: Sneaks in a warm, savory background note. Just enough to make you notice, never too much.
Easy How-To
- Start Baking
- Fire up your oven to 350°F and move the rack to the middle spot so heat gets everywhere. Line a pan with parchment—that way your croissants won't stick and clean-up's a breeze.
- Prep Croissants
- Grab a serrated knife and slice those croissants open sideways, keeping their shape intact. Go easy so you don’t smash the fluffy layers. Want more crunch? Toast them cut-side down in a pan before building them.
- Dijon Base
- Smear a little Dijon on each open side, mostly on the bottom. It’ll give just enough zing underneath the main flavors.
- Layering Magic
- Lay out your ham on the bottom piece. If it's too big, fold it so it fits. Top that with cheese—it should hang over the ham a bit so you get those epic melty edges.
- Sandwich Time
- Pop the top back on each croissant. Gently press down. You want it snug, but not so tight that the flaky bits get crushed.
- Buttery Finish
- Brush each croissant top with a layer of melted butter. Use a pastry brush and do a quick lap over each for max coverage—think glossy and delicious.
- Extra Touch
- If you're feeling fancy, sprinkle some thyme and garlic powder all over the tops. It'll look pretty and add a tiny bit more flavor.
- Into the Oven
- Space your croissants on the tray—don't crowd them. Bake about 10-12 minutes till the tops are shiny gold and the cheese bubbles through. The result? Toasty outsides, melty centers—best of both worlds.

When I first made these, I learned something big about where cheese goes. I tried putting the cheese right under the top croissant, but it just got messy. Laying cheese over the ham, not next to the bread, made it melt better and saved the bottom from getting soggy. Now I always go ham first, then cheese—total game changer.
Serving Ideas
These croissants fit in anywhere. Add fresh fruit or a handful of greens with a splash of vinaigrette on the side for breakfast or brunch—you’ll balance out the richness. Making lunch? Grab a cup of tomato soup and start dunking. It turns this simple sandwich into a full meal.
Fun Twists
This dish is a total blank canvas. Feeling Mediterranean? Toss in some sliced olives and roasted red peppers. If brunch is more your thing, sneak in a thin layer of scrambled eggs before the ham. Want sweet and salty? Swap the mustard for a bit of fig jam. Magic.
Storing Leftovers
If you're saving a few, wait till they're totally cool, wrap each one in parchment, and pop them in an airtight container. They'll last fine for two days on the counter. Skip the microwave—just rewarm them at 325°F for about 5-7 minutes. Your parchment wrap will keep them from drying out or going soggy.

I've made these ham and cheese croissants so many times for family and friends. You get that perfect mix of wow factor without a ton of hassle. Simple stuff plus a few easy moves, and suddenly breakfast or dinner feels fancy. Whether it's an easy brunch or weeknight comfort with soup, these always hit the spot and make you look like you tried way harder than you did.
Recipe FAQs
- → Can I swap the cheese for something else?
- Definitely! While cheddar (smoked or regular) is suggested, you can use Swiss, Gruyère, Havarti, or provolone for a twist. Feeling adventurous? Pepper jack adds some spice. Just pick a gooey cheese that melts nicely.
- → What's the best reheating method?
- Oven's the way to go! At 350°F (175°C), about 10 minutes should do it to keep them crispy. Got a toaster oven? That’ll work too. If you're in a hurry, microwaving for 30-45 seconds is okay, but expect a softer texture.
- → Can I freeze them to store for later?
- Sure can! Either freeze them before or after baking. For unbaked ones, skip the egg wash, freeze on a tray, then put them in a storage bag once solid. When baking from frozen, add 5-7 extra minutes. Already-baked croissants can be cooled, wrapped, and frozen for up to two months.
- → What can I serve alongside these croissants?
- These go great with fruit, yogurt, or a fresh salad for breakfast. For lunch, a bowl of soup or some chips makes a good match. Hosting brunch? Pair them with bacon, scrambled eggs, or even mimosas to make it special.
- → How do I make these vegetarian-friendly?
- Skip the ham and get creative! Extra cheeses, or cooked veggies like roasted peppers, spinach, or mushrooms, work great. You can even try vegetarian meats. Just make sure your veggies aren’t too wet to keep things crispy.
