Over the past few years, I have a grown to really love puff pastry. There’s just something so interesting about the dough – how it easily translates from appetizer to the main dish, down to a sweet treat.
Not too long ago, I whipped up a tomato tart and was impressed with how easy it was to put together. Today, I wanted to share with you my Mushroom Puff Pastry Appetizer that I made on a whim (and totally glad that I did!)
Love mushrooms? Try our mushroom and onion baked chicken for dinner! If you’re hosting a party, these little appetizers pair really well with tomato tarts.
How To Make Mushroom Appetizers With Puff Pastry
When it comes to being a food blogger, I usually take my time to sit down, research, and develop recipes.
But sometimes, spontaneity is fun – tons of fun.
At my weekly trip to the grocery store, I knew I wanted to put together a Mushroom Puff Pastry Appetizer – but I didn’t exactly know in what way. So I gathered the essentials: mushrooms (duh!) and a box of frozen puff pastry. The rest, I figured, would be done impulsively. In fact, this recipe is so easy, that you can make it in a few minutes too!
What You Need:
Here’s what you’ll need from the store. The exact amounts are in the printable recipe card at the bottom of this post.
Kitchen Tools Needed:
- Baking Sheet
- Parchment Paper
- Rolling Pin
- Frying Pan
- Electric Hand or Stand Mixer
- Paring Knife
- Offset Spatula
Ingredients Needed:
- Store-bought frozen puff pastry
- Flour
- Butter
- Mushrooms
- Cream Cheese
- Egg
- Parmesan Cheese

Mushroom Appetizer Tips
Here are some more tips that will help you as you make this super-simple appetizer. I also have some photos of the process so you can see it in action.
Cut The Puff Pastry Evenly
You want them to bake at the same rate, so cut them the same size. I used a paring knife for this step and it went really fast.

Use An Electric Mixer For The Cheese Mixture
It’s possible to make the cheese and egg mixture by hand, but it will take a lot longer. A stand or electric mixer is worth the investment.
Beat the cream cheese and egg. Then gently fold in the parmesan cheese.

Saute Mushrooms With Butter
This will caramelize the mushrooms so it brings out their natural sweetness. After they are darker brown, add them on top of the cheese mixture.
Then, just bake them for about 20 minutes.

How To Know When Puff Pastries Are Done
You will know they are done baking when they are inflated and a darker golden color.


Mushroom Appetizer With Puff Pastry
SERVINGS
Equipment
- baking sheet
- Parchment Paper
- Rolling Pin
- Non-Stick Skillet
- Paring Knife
- Electric Mixer and Bowl
- Oven
Ingredients
- 1 Store-bought frozen puff pastry (397 g) thawed
- 2-3 tbsp flour for rolling
- 1 tbsp butter
- 3 brown mushrooms cut into small pieces
- 6 tbsp cream cheese softened
- 1 egg
- 1 cup shredded parmesan cheese
Instructions
- Preheat oven to 400 degrees F.
- Line a baking sheet with parchment paper – set aside.
- Sprinkle a clean working surface with flour and rollout puff pastry until it’s about ½ an inch in thickness.
- Use a paring knife to cut the puff pastry into squares, about 2 inches x 2 inches in size. From 397 grams of puff pastry, you can get approximately 30 squares.
- Gently place each puff pastry square on the lined baking sheet. Refrigerate while you prepare the mushroom and cheese filling.
- Melt butter on a small non-stick skillet over medium heat. Add cut mushrooms and cook for about 2 minutes, until sweating. Remove from heat.
- In a medium-sized bowl, use an electric mixer to slowly beat cream cheese and egg. Once well combined, add parmesan cheese and fold.
- Remove puff pastry from the refrigerator. Use an offset spatula to scoop about ½ tbsp of cream cheese mixture on the center of each puff pastry. Top off with mushroom mixture.
- Bake for 17-20 minutes. Allow to cool for a few minutes (and to allow the puff pastry to deflate a little). Serve and enjoy!
