These Easy Mushroom Tartlets made with cheese and herbs adorned on mini puff pastry squares are delightful appetizers for any occasion.
Here’s a quick and easy mushroom puff pastry appetizer for this holiday season. If you have been following me for some time now, you will know that I love small bites. I enjoy preparing mini bakes for any occasion, and these tartlets; are bite-size flaky goodness!
This mushroom tart is easy to put together. The recipe calls for all butter store-bought puff pastry squares. However, you can use homemade puff pastry dough or buy a puff pastry sheet and cut it into small squares.
I used 6; 4-inch squares for these tartlets. I cut each 4-inch square into 2-inch squares to make it bite size.
Ingredients for the Easy Mushroom Tartlets
Mushroom– This filling is made: with button mushrooms. You could use any mushroom of your choice.
Onion– I like using red onion in my recipes.
Herbs & Spices – Thyme, red chili flakes, garlic, and salt. If you have fresh thyme, add about 1 1/2 teaspoons. Red chili flakes are for little heat, but you can leave them out if you don’t like them.
Add 1 large clove of garlic finely chopped. However, I wouldn’t recommend adding garlic powder to this recipe.
I used fresh chives. Feel free to use dried chives or scallions( green/ spring onions) for this recipe.
Cheese – The recipe calls for Emmental cheese slices and grated parmesan cheese. You can always use grated Emmental cheese.
Other cheese options are Gruyère or Cheddar cheese.
Puff Pastry – Use a good quality all-butter puff pastry for this. I used 6; 4-inch squares for these tartlets. If you cannot find the square-shaped puff pastry, buy a sheet of puff pastry and cut them into 6 – 4 inch squares and then each into 2-inch squares. It makes 24 mushroom tartlets.
Egg – 1 egg to egg wash the pastry.
How to make Mushroom Tartlets
The filling for this recipe is easy to prep with very few ingredients. First, saute the mushrooms, onion, garlic, salt, thyme, chili flakes, and chives; take the mushroom filling off the heat and cool it completely.
Next, add the grated parmesan to the filling and mix well.
Now, Cut each 4-inch square into 2-inch squares. Once you have cut the squares, place the pastry squares on a sheet pan and dock (prick) them with a fork. Brush the pastry squares with egg wash.
Cut the Emmental cheese slices into small squares.
Place the small cheese slices or a little grated Emmental cheese on the pastry squares.
Finally, put 1/2 Tablespoon of mushroom filling on top of the cheese. Bake the tartlets at 392F/200C preheated oven for 15 – 18 minutes or until golden brown. Serve warm.
Can I make these ahead?
These Mushroom Tartlets are best had when it is freshly baked. However, these tartlets can be made a day ahead and stored in an airtight container in the refrigerator. Reheat just before serving at 338F/170C for 5 -7 minutes.
You can also make the filling ahead of time and assemble the tartlets on the day of the event.
