These Ham Cheese Puff Pastries are an easy, savory bake that turns simple puff pastry, chopped ham, shredded cheese, mustard, and egg yolks into golden, flaky pastries.
Each pastry has a crisp, beautifully browned exterior that gives way to layers of tender puff pastry surrounding a warm, flavorful filling.
The combination of ham and melted cheese creates a classic savory center, while a small amount of mustard adds a tangy layer that keeps the filling from tasting too rich.
Dijon, grainy, or yellow mustard can be used, giving you flexibility while preserving the pastry’s overall character.
The chopped ham brings a satisfying meaty texture, while cheddar or Gruyere melts into the filling for a creamy, savory bite.
The preparation is straightforward and makes good use of leftover ham. Defrosted puff pastry is divided into individual squares, then layered with mustard, ham, and shredded cheese.
Each piece is folded into a neat parcel and sealed with egg yolk before baking.
The egg yolk brushed over the surface helps create the characteristic golden finish as the pastries bake.
With just 10 minutes of preparation and about 20 to 25 minutes in the oven, these pastries are practical for breakfast, brunch, or a simple savory snack.
They are especially appealing when served warm, when the puff pastry is crisp and the cheese is freshly melted.
The recipe yields 9 servings, making it convenient for sharing at a casual breakfast or brunch gathering.

Ingredients
Equipment
Method
- Prepare the Puff Pastry: Defrost the puff pastry sheets, then cut each sheet into 9 equal squares by cutting it into thirds in both directions, creating 18 squares total. Arrange the squares on a greased or parchment-lined baking sheet.
- Add the Mustard: Spread ¼ teaspoon of mustard diagonally across each puff pastry square, using Dijon, grainy, or yellow mustard according to preference.
- Fill the Pastries: Place about 1 tablespoon of chopped ham over the mustard on each square, then add 1 tablespoon of shredded cheddar or Gruyere on top of the ham.
- Seal the Pastries: Spread a small amount of egg yolk onto one corner of each pastry square, making sure that corner is not one of the corners containing the ham, cheese, and mustard. Fold the opposite corner over the filling, then fold the egg-coated corner over the first folded corner and press to seal. Repeat with all 18 pastry squares.
- Brush with Egg Yolk: Brush the top of each sealed pastry with egg yolk, coating the surface for a golden finish during baking.
- Bake Until Golden: Bake the pastries at 350°F for 20–25 minutes, or until the puff pastry is golden brown.
Notes
- Use fully defrosted puff pastry so the squares can be cut and folded without cracking.
- Dijon, grainy, or yellow mustard can be used according to the original recipe.
- Keep the ham and cheese centered over the mustard so the pastry can be folded and sealed properly.
- Make sure the egg-yolk-coated corner does not contain filling before folding, as this helps create a secure seal.
- Brush the tops evenly with egg yolk to encourage an attractive golden-brown finish.
- Bake until the pastries are visibly golden brown, using the 20–25 minute baking time as the source guideline.
Chef’s Secret
The most useful trick for these pastries is to pay close attention to where the filling sits before folding each puff pastry square.
Keep the ham, cheese, and mustard positioned away from the corner that will receive the egg yolk, leaving that corner clear for sealing.
When folding, bring the opposite corner over the filling first, then place the egg-coated corner over it and press firmly enough to hold the layers together.
This simple arrangement makes the folding process much easier and helps keep the filling enclosed as the pastries bake.
A consistent amount of filling in each square also makes the pastries easier to seal and keeps the finished batch uniform.
