filled puff pastry with cheese, mushrooms and spinach on plate

You would never know from the abundance of recipes on the blog containing mushrooms, that I’m a recently converted mushroom fan.

That’s right, mushrooms were not my favorite vegetable growing up. As I tried different varieties of mushrooms in a variety of dishes, I realized that I absolutely love them!

From Portobello Stuffed Mushrooms to Brussels Sprout Mushroom Casseroles to Creamy Mushroom Chicken Parmesan, I seriously can’t get enough of this Vitamin B packed veggie!

This particular recipe was actually inspired by a Mushroom Empanada from one of of my favorite Spanish Tapas Restaurants in San Diego, Cafe Sevilla. I love the flaky, buttery empanada dough wrapped around the rich, hearty mushrooms and melty, delicious cheese!

Instead of re-creating this dish as an empanada, I decided to make this scrumptious spinach puff pastry recipe. The puff pastry still gives it that flaky, buttery crust that I love, yet I put my own twist on the recipe!

Ingredients

  • Unsalted butter
  • Baby bella mushrooms – you could use another variety of mushrooms, like white button if you prefer, or you could dice up a large portobello mushroom. I prefer the deep, earthy flavor of the baby bella mushrooms, also known as crimini mushrooms.
  • Garlic – I always recommend fresh-minced cloves for the best flavor.
  • Baby spinach
  • Salt + black pepper – to season the filling.
  • Cheddar cheese – I’ve made this recipe with traditional white cheddar cheese, and garlic herb cheddar. Both are delicious and work great in this recipe. You could even sub in shredded Monterey jack or gouda cheese.
  • Puff pastry sheet – I love how easy it is to find pre-made puff pastry dough sheets at the grocery store in the freezer section. It makes this recipe so easy to make in no time at all! Just don’t forget to thaw the puff pastry! Remove one sheet of dough from the freezer, and the packaging, to allow it to defrost for at least 30 minutes before starting this recipe.
  • Egg – you’ll need one large egg for this recipe to make the egg wash. This helps the top of the puff pastry turn golden brown.

Instructions

Preheat the oven to 425°F.

Heat a large skillet over medium heat, then add butter.

Once the butter has melted, add sliced mushrooms and cook for 5-7 minutes. Add minced garlic and cook for 1-2 minutes, then add spinach leaves and sprinkle salt and pepper over the top.

Cook for an additional 3-4 minutes, then turn the heat off and set the skillet aside.

Roll the puff pastry sheet out on to a large piece of parchment paper.

If you would like to get fancy with the braided top (which is actually super simple!) follow the next step.

If you would like to keep it simple, you can simple wrap the puff pastry around the ingredients without the braid.

To make the braided top, slice a triangle from the bottom of the dough, then slice ½ inch diagonal lines up each side of the pastry, like so ↓

If you’re keeping it simple, fold the sides of the puff pastry over.

If you’re using the braid method, lay the rectangular end of the puff pastry over the filling, then begin on one side, and lay one strip of dough over the filling, then alternate laying a strip of dough from the other side, then alternate back and forth, back and forth, over the filling.

Once the entire puff pastry is wrapped up, transfer it on the parchment paper to a baking sheet.
