1sheet puff pastry, defrosted according to package instructions
1egg
1tbspmilk
1 1/2cupsgrated Gruyere cheese
6pieces of ham
2-4tbspdijon or grainy mustard
ground pepper, salt and dried thyme or Italian seasoning; or, everything bagel seasoning
fresh thyme leaves for garnish
Instructions
Preheat the oven to 425F and line a large baking sheet with parchment paper.
Make an egg wash by whisking the egg with 1 tbsp milk.
Roll out tone piece of puff pastry and use a sharp knife to cut into 6 rectangles / squares by slicing once lengthwise and then three time width-wise. Place the 6 rectangles / squares on the parchment lined baking sheet.
Brush the outer edges of the puff pastry with egg wash.
In the center of each rectangle spread 1-2 tsp of dijon or grainy mustard (use as much or as little depending on your tastes); followed by placing 1/4 cup of shredded Gruyere cheese on top of the mustard on an angle from one corner to another; and, then top the cheese with a piece of ham that's been rolled up so it's not falling out of the puff pastry.
Lift one corner of the puff pastry rectangle and place it over the ham. Brush a bit of the egg wash on top of the puff pastry. Then grab the opposite corner of the puff pastry rectangle and bring it on top of the other piece to seal. (See photos in blog post if needed).
Brush the egg wash over each bundle and sprinkle with a bit of ground pepper, salt and dried thyme or Italian seasoning; or, everything bagel seasoning (whatever you have on hand).
Bake until puffed and golden brown, about 18-22 minutes. Serve immediately.
Notes
Use a sliced ham like black forest ham or virginia, or leftover spiral or glazed ham or even an Italian ham like prosciutto
Use everything bagel spice or sesame seeds as a fun topping instead of dried thyme or italian seasonging.
If using frozen puff pastry, make sure to defrost it according to package directions well ahead of time. I like to place it in the fridge overnight to be ready to use the next day.
