This modern take on the Monte Cristo sandwich combines prosciutto, cheddar cheese & raspberry jam in a flaky puff pastry crust, baked and glazed with honey.

Baked Puff Pastry Monte Cristo

Some foods instantly bring back a memory. For me, the Monte Cristo sandwich conjures afternoons at a family restaurant in Oklahoma, sharing a large, sweet, fried sandwich with my brother and grandparents. Years later, a refined brunch version I tried in Washington, DC, rekindled that affection—and inspired this lighter, baked adaptation made with puff pastry.

The brunch version that sparked this recipe featured honey-glazed prosciutto, a blend of cheeses and orange marmalade on house brioche. I wanted the same sweet-savory balance but in a much lighter format, so I swapped brioche and frying for flakey puff pastry and the oven. The result: a portable, elegant Monte Cristo pocket with crisp, buttery layers, prosciutto, sharp cheddar and a spoonful of raspberry jam, finished with a drizzle of honey.

This version is quick to put together, bakes in about 20 minutes, and makes four individual sandwiches—perfect for brunch, a light dinner, or as an impressive appetizer. Because the pockets are baked rather than deep-fried, they feel less heavy while still delivering the classic contrast of salty prosciutto, melted cheddar, and fruity jam.

Puff Pastry Monte Cristo Sandwich Ingredients

1 egg
1 tbsp water
1 sheet puff pastry dough
2 tbsp raspberry jam (more for serving, if desired)
8 slices (about 4 oz) prosciutto
1 cup shredded cheddar cheese
2 tbsp honey

Puff Pastry Monte Cristo Sandwich Instructions

Preheat the oven to 400°F (200°C).
Whisk the egg and water together in a small bowl to make an egg wash, and set aside.
On a lightly floured surface, roll the puff pastry sheet slightly to smooth any creases, then cut it into four equal squares.
Brush the edges of each square with the egg wash to help seal the pockets.
Spread approximately ½ tablespoon of raspberry jam into the bottom corner of each square (or use a small spoonful in the center if you prefer).
Top the jam with 2 slices of prosciutto on each square, then sprinkle about ¼ cup shredded cheddar over the prosciutto.
Fold each square over into a triangle and press the edges together firmly, crimping with a fork to seal.
Place the filled pockets on a baking sheet lined with parchment paper. Brush the tops with the remaining egg wash for a glossy finish.
Bake in the preheated oven for about 20 minutes, until the pastry is golden and puffed and the cheese has melted.
Remove from the oven and immediately drizzle about ½ tablespoon of honey over each warm sandwich so it melts slightly into the pastry.
Serve warm with extra raspberry jam on the side for dipping.

Recipe Notes, Variations & Tips

Cheese: Cheddar gives a nice sharp contrast to the sweet jam. You can experiment with Gruyère, Swiss, or a blend of cheeses for a nuttier flavor.
Jam: Raspberry jam works beautifully, but apricot, orange marmalade or fig jam are excellent alternatives depending on your taste.
Prosciutto alternatives: Thin-sliced ham or smoked turkey can be used if prosciutto isn’t available.
To make ahead: Assemble the pockets and refrigerate on a parchment-lined tray, covered, for up to 24 hours. Brush with egg wash just before baking.
Serving suggestions: These pockets pair well with a simple green salad for a light meal or with fruit and a small side of greens for brunch.
