I’m starting to think about my Easter menu already and these tarts are getting me insanely excited! Classic chicken cordon bleu is one of our favorite main course choices on Easter so naturally the puff pastry tart version of them can only raise the bar.
And these little beauties do exactly that while being cute as heck AND layered with all kinds of goodness at the same time! Excuse me while I make a meal solely out of that pan down there.

(scroll down to the bottom of the post for the full recipe)
Ingredients You Will Need
- Puff pastry
- Honey
- Dijon mustard
- Whole-grain mustard
- Mayonnaise
- Parsley
- Swiss cheese
- Deli chicken
- Deli ham
- Egg white
- Arugula
How to Prepare Puff Pastry
To prepare the puff pastry for baking, you will first want to thaw it completely in refrigerator. I recommend removing it from the freezer and transferring to the fridge a few hours before baking.
Turn puff pastry onto a floured surface, roll out into a 10 x 10 inch square, and use a sharp knife or a pizza wheel to cut square into 9 equal squares. Now prick the squares all over to allow steam to escape during baking.

Tips for Perfect Puff Pastry Tarts
- Pre-bake puff pastry squares – bake the puff pastry squares at 400F for 10 minutes before adding the other ingredients. This pre-bake allows the pastry set up a bit before adding filling.
- Spread some of honey mustard on pastry – save the other half for drizzling over tarts after baking.
- Layer quarter slices of cheese, chicken, and ham – cut the slices in quarters for easy layering that will fit inside the pastry squares.
- Brush edges of tarts with egg wash – a quick egg wash brush on the pastry will help them brown.
Recipe Variations
Try these ideas for a different twist on these tarts.
- Use another meat – try beef or turkey slices.
- Try another cheese – try white cheddar, gouda, pepperjack, or mozzarella.
- Top tarts with breadcrumbs – toast 1/2 cup breadcrumbs and toss with 1 tablespoon butter. Sprinkle over baked tarts while warm.
Make Ahead Instructions
Follow these instructions for time-saving make ahead tips.
- Thaw, roll, and cut pastry squares – keep the pastry squares chilled in refrigerator up to 6 days until ready to bake.
- Make honey mustard – make the honey mustard and store in refrigerator up to 6 days.
- Assemble cheese and meats – layer the cheese and meats on top of each other and store in refrigerator up to 6 days until ready to bake.

Your next brunch event isn’t ready for this goodness! All the layers of meat, gooey Swiss, and flaky pastry bake together like a dream and that little sprinkle of peppery arugula on top brings all the flavors together.
ALMOST better than the real thing.
