Instructions: Step-by-Step Guide to Perfect Ham and Cheese Puff Pastry Squares

This section will walk you through the entire process of making your puff pastry squares—from preparing your workspace to baking and serving. Whether you’re making these as a quick snack, a party appetizer, or part of a brunch spread, follow these instructions to get the best possible results.

Step 1: Gather and Prepare Your Ingredients

Before diving into assembly, it’s essential to have all your ingredients measured and ready to go. Here’s what you’ll need for a basic batch of 12 squares:

Ingredients:

• 1 sheet of puff pastry (preferably all-butter, about 10 x 10 inches), thawed if frozen

• 6 slices of deli ham (or about 4 oz), thinly sliced

• 1 cup shredded cheese (Swiss, Gruyère, cheddar, or a combination)

• 1 egg, beaten (for egg wash)

• 1 tablespoon whole grain or Dijon mustard (optional, for flavor depth)

• Freshly ground black pepper (optional)

• A pinch of dried thyme or rosemary (optional)

• Flour for dusting the surface

Prep Tips:

• If using frozen puff pastry, allow it to thaw in the refrigerator overnight or leave it at room temperature for 30–40 minutes until pliable but still cool.

• Keep the pastry cold until you’re ready to work with it to ensure the best texture and flakiness.

• Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or a silicone mat.

Step 2: Prepare Your Work Surface

Lightly dust your countertop or work surface with flour to prevent the pastry from sticking. Unfold the thawed puff pastry gently onto the surface. If there are any creases, smooth them out with a rolling pin. You’re not aiming to thin out the dough significantly—just to even out the surface and edges.

Step 3: Shape and Cut the Dough

Using a sharp knife or pizza cutter, cut the puff pastry sheet into 12 equal squares. The easiest way to do this is to:

• First cut the sheet into 3 vertical strips.

• Then cut each strip into 4 squares.

If you prefer smaller, bite-sized pieces, you can cut 4×4 instead of 3×4 to make 16 squares.

Tip: For perfectly uniform squares, use a ruler or a clean-edge guide to keep lines straight.

Step 4: Add Fillings

Arrange half of your pastry squares on the prepared baking sheet. These will be the bases. The remaining squares will act as the tops.

On each base square:

• Add a small dollop (¼ to ½ teaspoon) of mustard, spreading lightly with the back of a spoon.

• Top with a portion of shredded cheese (about 1 to 2 tablespoons).

• Add a small folded piece of ham over the cheese.

• Sprinkle with a touch of black pepper or herbs, if desired.

Be sure to leave a small border (about ¼ inch) around the edge to allow for sealing.

Step 5: Seal and Crimp the Edges

Take the remaining squares and gently lay one over each filled base square.

Using your fingers, press around the edges to seal the two layers of pastry together. Then, use the tines of a fork to crimp the edges firmly—this adds a decorative edge and ensures the filling stays inside during baking.

Tip: If the pastry isn’t sealing well, brush the border of the bottom square lightly with water or egg wash before sealing.

Step 6: Egg Wash for Golden Color

In a small bowl, beat one egg with a tablespoon of water. Brush the tops of each pastry square lightly with the egg wash using a pastry brush.

This step gives the final product that beautiful, glossy golden finish once baked.

Optional: For a more artisan look, you can sprinkle the tops with sesame seeds, poppy seeds, or a pinch of flaky sea salt.

Step 7: Ventilation and Final Touches

To prevent the puff pastries from becoming soggy and to help steam escape, use a small knife to score a tiny “X” or two short slits in the center of each top.

Don’t skip this step—proper venting improves texture and avoids bursting during baking.

Step 8: Bake to Perfection

Place the prepared tray into your preheated oven and bake for 18 to 22 minutes, or until the puff pastry is golden brown, crisp, and puffed up.

Check around the 15-minute mark to ensure they’re browning evenly. You can rotate the tray if needed to promote uniform baking.

Tip: Baking times can vary depending on your oven and the thickness of your fillings, so keep an eye on them in the final minutes.

Step 9: Cool Slightly Before Serving

Remove the puff pastry squares from the oven and let them rest on the tray for about 5 minutes before transferring them to a wire rack.

This allows the cheese to set slightly and avoids burning your mouth with molten filling.

Serve warm or at room temperature.

Step 10: Serving Suggestions

These pastries are incredibly versatile. Here are a few ideas to serve them:

• As an appetizer on a wooden board with dipping sauces like honey mustard, aioli, or tomato chutney.

• Paired with a crisp green salad for a light lunch.

• On a breakfast or brunch spread with fresh fruit, coffee, and juices.

• As part of a picnic basket or potluck table.
