What Goes in Mushroom Tart
- Mushrooms: You can use any type of mushrooms that you like, I went for chestnut/cremini brown mushrooms, but by all means, go for any type of mushrooms that you have available. Whether it’s white button mushrooms, wild mushrooms, or porcini mushrooms, it will taste amazing!
- Puff Pastry: I recommend getting an all-butter puff pastry. You have to read the label, but many brands use shortening and other types of fat. If you can’t find it, use pie crust instead.
- Cheese: I used Edam (semi-hard cheese), but Gruyere or raclette go very well here. You can also go for a mix of cheddar and mozzarella.
- Garlic, onion, and fresh thyme (you can also use rosemary).
- Olive oil, butter, salt, pepper, and an egg for the egg wash.
How To Make Mushroom Tart
If you’re using frozen puff pastry, you have to make sure that it’s thawed. I recommend that you thaw the frozen puff pastry in the fridge overnight, but if you don’t have time then you can leave it on the counter at room temperature to thaw. But, when puff pastry is warmed up it will melt so you really have to catch it during that sweet spot when it’s thawed but not melted? So keep an eye on it!
To make the mushroom tart, it’s just 4 simple steps:
- Saute the mushrooms. Feel free to change things up and add other ingredients such as onions or even cherry tomatoes. But no matter what you do, always make sure that you’re using enough garlic because there’s nothing better than garlicky mushrooms in a mushroom tart!
- Line a sheet pan with parchment paper, this will prevent the puff pastry from sticking to the sheet pan. Unroll the puff pastry sheet, then score the edges (create a border) and this will create your crust. Then using a fork prick the puff pastry sheet.
- Grate some cheese, and sprinkle it over the puff pastry sheet.
- Top with the sauteed mushrooms, and bake!
With the same method, the possibilities are endless! Make a mixed vegetable tart, tomato tart, asparagus tart, you name it! You can get as creative as you’d like, and add your own seasonings and flavors to make your own creation inspired by this mushroom tart.
Also keep in mind that this mushroom tart reheats beautifully. You can either reheat it in the microwave, or in the oven just for a couple of minutes until it’s warmed up. And you can even freeze it.
What To Serve Mushroom Tart With
Serve this mushroom tart warm as an appetizer, side, or even main. It goes so well with a side salad and a portion of french fries or oven-baked fries.

Mushroom Tart
Ingredients
- 2 tablespoons olive oil
- 3 cups (200g) mushrooms
- ½ teaspoon salt
- ¼ teaspoon ground black pepper
- 1 tablespoon butter optional
- 2 cloves garlic minced
- 1 tablespoon fresh thyme chopped
- 1 sheet puff pastry
- 1½ cups (125g) grated cheese Edam, Gruyere, raclette, or a mix of cheddar and mozzarella.
- 1 egg for the egg wash
- ¼ teaspoon chili flakes optional
Instructions
- Preheat oven to 180°C/350°F (160°C/320°F fan).
- On medium heat, heat olive oil in a pan. Add the mushrooms, season with salt and pepper, and cook stirring occasionally until the mushrooms release their liquids and it cooks off (about 8 minutes).
- Melt butter (optional)*, and saute garlic until its fragrant. Add thyme, cook for a minute, and remove from heat.
- Line a baking sheet with parchment paper, this will prevent the puff pastry from sticking to the sheet pan. Unroll the puff pastry sheet, then score the edges using a sharp knife leaving a 1-inch border. Then using a fork, prick the puff pastry sheet.
- Top the puff pastry with grated cheese, followed by sauteed mushrooms.
- Using a pastry brush, brush the border with an egg wash.
- Bake for 12-15 minutes, or until the puff pastry is puffed and lightly browned.
- Sprinkle some chili flakes if desired, then cut into 6 squares, and serve warm.
Notes:
- If using frozen puff pastry, let it thaw completely before using (preferably overnight in the fridge).
- Keep the puff pastry in the fridge until you’re ready to use as otherwise it will melt and become too soft and difficult to handle.
- I used an All-Butter Puff Pastry sheet that was 320g in weight, which is around 11 ounces.
- Adding butter to the sauteed mushrooms is optional, it adds more flavor but if you don’t want the tart to be too buttery then omit the butter.
- Feel free to saute an onion with the mushroom.
- Other herbs that go well with the filling are rosemary and oregano

does the melted butter, garlic, thyme get added to the cooked mushrooms?
pastry does not need to baked at all prior to toppings?
Thank you!
making his tomorrow:)
Diana says
Hi Carol, yes all added to the mushrooms. No need to prebake the puff pastry before adding the toppings. There’s a video in the recipe card that you might find useful. Enjoy!
Melissa says
This is wonderful! I’ve made it twice now. The first time, I thought it was too bland, so the second time around I used quite a bit of ground pepper, and about 1 tsp. of red pepper flakes – and I sprinkled them on before I baked it.
I substituted dried Rosemary for the Thyme, and used Swiss cheese.
Everyone who had some is asking for the recipe.
Maria Hudon says
Cheese is not included in the printable recipe. How much grated cheese?
Diana says
Good catch, Maria! I used about 1.5 cups of grated cheese, but you can use more if you like.
