Mini Ham and Gruyère Quiches are the perfect bite-sized appetizer for your spring celebrations. Whether you’re hosting an Easter brunch, a Mother’s Day gathering, or a bridal shower, these savory tarts offer a sophisticated yet simple solution for feeding a crowd.

I didn’t make the crust from scratch; instead, I used store-bought puff pastry. It makes preparing these mini quiches incredibly easy and, honestly, I feel it is better than many homemade doughs for this specific application. It’s buttery, flaky, and takes no time at all to prepare. For more inspiration on using similar ingredients, check out this Greek Ham and Cheese Pie (Zambonopita).

Ingredients for Mini Ham and Gruyère Quiches
To make these delicious Mini Ham and Gruyère Quiches, you will need the following simple ingredients:
- Cooking Spray: To prevent sticking in the muffin tin.
- All-Purpose Flour: For dusting the surface when rolling out the pastry.
- Frozen Puff Pastry: Thawed according to package instructions. This is the secret to easy, flaky crusts.
- Eggs: Large eggs form the base of the custard filling.
- Half-and-Half: Adds creaminess to the egg mixture without being too heavy.
- Gruyère Cheese: A nutty, melty cheese that pairs perfectly with ham. If you can’t find it, Swiss or Emmental works well too.
- Ham: Diced cooked ham. You can use leftover holiday ham or deli ham.
- Dijon Mustard: Adds a tangy depth of flavor.
- Fresh Thyme: For an aromatic, earthy note.
- Kosher Salt & Black Pepper: To taste.

Step-by-Step Instructions
Step One: Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly spray a 12-cup muffin tin with cooking spray to ensure the quiches release easily after baking.
Step Two: Prepare the Puff Pastry Crusts
On a lightly floured surface, roll the thawed puff pastry slightly to seal any seams. Cut the pastry into 12 equal squares. Gently press each square into a muffin cup, leaving the corners slightly raised above the rim for a rustic look. Use a fork to prick the bottom of each pastry square 2 to 3 times to prevent excessive puffing during baking.

Step Three: Egg Wash the Crusts
In a small bowl, beat one egg until smooth. Using a pastry brush, lightly brush the sides of the puff pastry cups with the beaten egg. This helps them brown evenly and creates a beautiful golden finish. This technique is similar to what you might use in other pastry recipes like these Palmiers (Elephant Ears).
Step Four: Make the Filling
In a large bowl, whisk together the remaining eggs, half-and-half, grated Gruyère cheese, diced ham, Dijon mustard, fresh thyme, salt, and pepper. Whisk until well combined. The mixture should be smooth and uniform.

Step Five: Fill and Bake
Divide the egg and ham mixture evenly between the prepared puff pastry cups, filling each cavity about 3/4 full. Be careful not to overfill, as the mixture will puff up slightly. Place the tin in the center of the oven and bake for 25 to 28 minutes, or until the quiches are golden brown and set in the center.

Step Six: Serve and Enjoy!
Allow the quiches to cool slightly in the pan before removing them. This helps them set further and makes them easier to handle. Serve hot or at room temperature. They pair wonderfully with a fresh green salad or fruit platter.

Tips for the Best Mini Quiches
- Don’t Skip the Pricking: Pricking the pastry prevents large air bubbles from forming under the filling.
- Cheese Choice: Gruyère is traditional, but you can experiment with other melting cheeses. For a different twist, try adding some cheddar as seen in this Broccoli Cheddar Soup concept.
- Make Ahead: These quiches are excellent for meal prep. See the FAQ section below for storage instructions.
- Variations: Add sautéed spinach, mushrooms, or caramelized onions for extra flavor and nutrition.
Frequently Asked Questions
Can I make these Mini Ham and Gruyère Quiches in advance?
Yes! These quiches are great for making ahead. Once cooked, let them cool to room temperature, then transfer to an airtight container and refrigerate for up to five days. To reheat, bake them in a 325°F oven for 8 to 10 minutes until warmed through.
I can’t find Gruyère! What else can I use?
Any type of sharp, nutty cheese works well. Good substitutes include Swiss, Comté, Emmental, or even a sharp white cheddar. The key is to use a cheese that melts well and has a distinct flavor.
Can I freeze these quiches?
Absolutely. Freeze the baked and cooled quiches on a baking sheet until solid, then transfer to a freezer-safe bag. They can be frozen for up to 2 months. Reheat in the oven from frozen, adding a few extra minutes to the baking time.
