- 3 ounces Gruyere, thinly sliced: This cheese melts beautifully and brings a nutty, savory depth.
- 1/2 Pink Lady or Honeycrisp apple, thinly sliced: Provides a crisp, sweet contrast to the salty ham and cheese.
- 2 teaspoons olive oil: Keeps the apples moist and adds a gentle sheen.

- Several sprigs fresh thyme: Adds a fragrant herbal note that ties everything together.
How to Make Ham & Gruyere Puff Pastry Tarts Recipe
Step 1: Preheat the Oven
Start by heating your oven to 400 degrees Fahrenheit. This high temperature helps the puff pastry puff up beautifully and turn golden crisp in just about 20 minutes.
Step 2: Prepare the Puff Pastry
Roll out the sheet of puff pastry gently on a lightly floured surface, smoothing any creases or fold lines. Trim the edges so they look neat and straight. Cut the sheet into six equal pieces by slicing down the center lengthwise and then into three sections across.
Step 3: Prepare the Pastry Borders
Place the pastry squares on a baking sheet lined with parchment paper. Use a sharp knife to score a 1/4 inch border around each piece but do not cut all the way through. Then prick the inside area with a fork to prevent it from puffing unevenly, keeping the edges crisp and defined.
Step 4: Layer the Flavors
Spread the stoneground mustard evenly inside the scored border on each pastry piece. Layer 3 slices of Gruyere cheese over the mustard, then add 2 slices of ham on top. Finally, fan out 3 to 4 thin apple slices across the ham. This layering makes for a perfect bite with each element shining through.
Step 5: Dress the Apples
Brush the apple slices lightly with olive oil to keep them moist and prevent drying out. Sprinkle a pinch of kosher salt and freshly ground black pepper over each tart to enhance the overall seasoning.
Step 6: Bake Until Golden
Pop the baking sheet into the oven and bake for 20 to 24 minutes. You’re looking for a beautifully puffed, golden crust and bubbly, melted cheese. Keep an eye on them towards the end so they don’t over-brown.
Step 7: Add the Finishing Touches
Once out of the oven, immediately drizzle each tart with honey for a touch of sweetness that balances the savory notes. Finish by garnishing with fresh thyme sprigs to add an earthy aroma that complements every bite.

Garnishes
Fresh thyme sprigs not only bring beautiful color but infuse the tarts with subtle herbal hints. For an extra pop, you might sprinkle some finely chopped chives or dot with a little crème fraîche to enhance creaminess.
Side Dishes
These tarts pair wonderfully with light, crisp salads—think arugula tossed with lemon vinaigrette or a simple mixed greens salad with shaved fennel. The freshness complements the richness of the tarts perfectly.
Creative Ways to Present
For a charming presentation, arrange the tarts on a rustic wooden board with scattered thyme leaves and a small bowl of honey on the side for guests to drizzle more if they wish. They also make excellent finger food for a cocktail party or brunch buffet.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, store the tarts in an airtight container in the refrigerator. They will stay fresh for up to 2 days, making for a quick snack or easy addition to the next day’s meal.
Freezing
You can freeze unbaked assembled tarts by placing them in a single layer on a baking sheet until firm, then transferring them to a freezer bag. Bake directly from frozen, adding a few extra minutes to cooking time. This is a great way to have impressive appetizers ready whenever needed.
Reheating
Reheat leftovers in a 350-degree Fahrenheit oven for about 10 minutes to revive the crispness of the puff pastry without drying out the ham and cheese. Avoid microwaving to keep the flaky texture intact.
FAQs
Can I use a different cheese instead of Gruyere?
Absolutely! While Gruyere is perfect for its melting quality and nutty flavor, Swiss or Fontina also work well if you want a milder taste. Just make sure to use a cheese that melts nicely.
Is it possible to make these tarts vegetarian?
Yes, simply omit the ham and add your favorite vegetables like caramelized onions, sautéed mushrooms, or roasted red peppers for a delicious vegetarian version.
What type of puff pastry should I use?
Store-bought frozen puff pastry sheets are ideal for convenience without sacrificing quality. Just be sure to thaw it according to package instructions before you start.
Can I prepare these tarts ahead of time completely?
You can assemble the tarts and keep them covered in the refrigerator for up to 24 hours before baking. Just bake them fresh to enjoy the best puff and crispiness.
What wine pairs well with Ham & Gruyere Puff Pastry Tarts?
A crisp white wine like Sauvignon Blanc or a light Pinot Noir complements the savory and sweet flavors beautifully, enhancing your overall dining experience.

Instructions
- Preheat Oven: Preheat your oven to 400 degrees Fahrenheit to ensure it’s properly heated for baking the tarts.

Notes
- Use firm apples like Pink Lady or Honeycrisp for the best texture and sweetness contrast.
