Crisp, rich sheets of puff pastry encase delicious ham and gooey cheese in these tempting hand-held treats. The kick from zesty Dijon mustard transforms these bites from ordinary to fancy, making them just right for anything from laid-back weekend meals to swanky get-togethers.
I whipped these up for our family gathering last Sunday, and my little nephew said they were "way tastier than the ones from that expensive bakery." The trick? Don't rush sealing the edges properly and make sure your pastry sheets thaw completely - cutting corners on either step won't give you the best outcome.
Key Components
- Puff Pastry: Should be totally defrosted but stay cool for optimal results
- Ham: Go for premium, thin-cut ham that isn't overly moist
- Aged Cheddar: Grate it yourself for smoother melting than packaged options
- Dijon Mustard: Brings a zingy contrast to cut the buttery richness
- Fresh Thyme: Adds a burst of flavor and pretty green flecks
- Egg Wash: Delivers that gorgeous golden finish

Comprehensive Preparation Steps
- Step 1:
- Begin with correctly thawed pastry - it needs to be cool yet flexible.
- Step 2:
- Smooth out gently to consistent thickness without handling too much.
- Step 3:
- Slice squares using a sharp blade for tidy borders.
- Step 4:
- Place filling in center areas to stop leakage.
- Step 5:
- Use just a little water when closing - excess moisture blocks proper puffing.
- Step 6:
- Press edges down thoroughly with fork.
- Step 7:
- Cut small air holes to let steam escape.
- Step 8:
- Brush egg mixture on top without letting it run down sides.
- Step 9:
- Keep an eye on them during last cooking minutes.
- Step 10:
- Let rest briefly before eating so filling firms up.
My grandma used to cook something like this whenever we had special family events, though she went with phyllo instead. These puff pastry ones are so much simpler but they always remind me of those lovely times helping her in the kitchen.
Do-Ahead Wonder
They're a lifesaver for busy hosts - just put them together and pop them in the freezer uncooked for up to two months.
Presentation Ideas
- Arrange them nicely on a serving dish with sprigs of herbs and some honey mustard sauce for dipping.
- Enjoy them warm but not piping hot to get that perfect stretchy cheese effect.

These ham and cheese puffs have become my favorite thing to make when people come over. They show how sometimes the easiest combos create the yummiest snacks, especially when they're wrapped in flaky, buttery dough.
Frequently Asked Questions
- → Can I prep these early?
- Absolutely! Freeze unbaked for up to two months. Bake directly from frozen and just add a few minutes to the baking time.
- → Why is chilling the dough important?
- It keeps the pastry flaky by helping it rise properly while baking.
- → What pairs well with these?
- Try them with spicy pepper jelly, honey mustard sauce, or a light salad on the side.
- → Can I try other cheeses?
- Definitely! Swap in gruyere or even sharp provolone for more variety.
- → Why cut slits on top?
- Those slits let out steam during baking, so the filling won’t spill out.
