Mushroom Galette Recipe
If you’ve never heard of a galette, it’s essentially a rustic pie or tart. On the blog, I’ve shared recipes for an apple galette and strawberry galette, which are both dessert galettes.
Today, I’m sharing this recipe for a savory galette, which is basically a mushroom tart.
If you’ve ever made a French onion tart, it’s not too different from that.
For this mushroom galette recipe, you’ll need pie dough for the pastry aspect.
You can make your homemade pie crust or simply use a sheet of store-bought pie dough.
Once you’ve got the pie crust ready to go, you’ll spread a layer of ricotta cheese over the crust, then top it with some grated parmesan for extra flavor.
The cheese is then topped with sautéed mushrooms and caramelized onions before all of the filling is topped with gruyere cheese.
The great thing about a galette is that it’s incredibly versatile. You can use all kinds of vegetables and cheeses to make a galette, so if you’re not a fan of mushrooms or you’re not a fan of gruyere, you can swap them out.
You could pile on sautéed veggies like zucchini, tomato, and bell pepper for a rustic summer version.
Or, turn this into a meat lover’s delight by incorporating ham or sausage.
If you are a fan of mushrooms, however, you are going to love the version shared here today, just as it is!
The combination of mushrooms with onions is divine. Anytime I make this for a gathering with friends, I always get people asking me for the recipe.
You can also enjoy this mushroom galette as a meal with a glass of crisp, white wine.
To serve the galette, simply cut it up into pizza-like slices. If you’re serving it as an appetizer, you’ll want to cut them into smaller slices.
If you’re serving it as a meal, you can afford to be more generous with your portions.
You can also prep this galette and freeze it for baking later. If you decide to make ahead and freeze, just be sure to increase the duration in which you bake the tart as it will likely need more time to bake through.

A savory tart made with flaky pastry and a delicious combination of cheeses, mushrooms, and caramelized onions.
Ingredients
1 sheet of pie dough
1/3 cup whole milk ricotta
6 oz. crimini mushrooms, cut into slices
1/4 of a jumbo white onion, cut into thin crescent-shaped slices
1.5 oz gruyere cheese, shredded
parmesan cheese, for grating as a garnish
pinch of salt and freshly ground pepper
pinch of nutmeg
1 egg, separated into white and yolk
olive oil
1 sprig of thyme
Instructions
Preheat the oven to 400°F. To a pan, add about a tablespoon of olive oil. Warm over medium heat and once hot, add in the onion slices. Cook until the onions begin to become golden along the edges and caramelize.
Add the mushroom slices to the pan and cook for another few minutes until the mushrooms are tender. Turn off the heat and temporarily set the pan aside.
Unroll the pie crust onto a baking sheet fitted with parchment paper or a silicone baking mat. Brush the egg white over most of the pie crust, leaving about a 1 1/2 inch perimeter bare. Let the crust rest for a minute for the egg white to slightly dry.
Spread the ricotta cheese all over the area covered with the egg white. Use a zester to finely grate a little bit of parmesan cheese as a slight garnish over all the ricotta cheese. Add a small pinch of salt and freshly ground pepper, as well as the pinch of nutmeg, over the cheese.
Distribute the mushroom-onion mixture all over the ricotta cheese, then top that with the shredded gruyere. Add the thyme leaves all over the top.
Fold the edges of the pie crust over the mushroom filling, all along the edges. Brush the egg yolk over the pastry, then top the pastry with some of the finely grated parmesan.
Bake the galette for 20-30 minutes. If you're using store-bought crust, it will typically look golden and be ready in the 20-25 minute mark, whereas homemade pastry can take up to 30 minutes.
Let the galette rest for 10 minutes on the baking sheet, then transfer to your serving plate.
Because you can't par-bake a galette crust to prevent the fruit's juices from making the crust soggy, many folks brush their galette crust with egg white or make a layer of crushed cookies or cake crumbs, either of which work fine.
A galette, if you're unfamiliar, is a kind of open-faced, freeform pie. The dough for the crust is the same as a traditional pie, but the structure of the dessert is different.
The website joyofbaking.com defines the term galette as "a French term signifying a flat round cake that can be either sweet or savory and while [recipes can use] puff pastry as a base, they can also be made from risen doughs like brioche, or with a sweet pastry crust."
Crust dust is a 1:1 mixture of flour and granulated sugar. When baking a pie, especially a fruit pie, a couple of teaspoons of crust dust sprinkled into the bottom of the crust will help prevent the crust from becoming saturated with juicy filling as it bakes.
The main difference is that tarts only have a bottom crust, and the crust is much thicker than a pie crust. Galettes – This is basically a pie made without using a pie dish, but because that would be too simple galettes can be made with any type of pastry dough.
The three most common types of galette are galette Breton, galette de rois, and fruit galette. A galette Breton is a buckwheat crepe. A galette de rois is a type of flat cake made with pastry dough. Finally, a fruit galette is a freeform pie shaped around the filling.
Crostata is an Italian term, and galette is French; however, by definition, you can use these terms interchangeably. They're referring to the same, easy and distinctly elegant dessert.
Remove the dough from the plastic wrap and roll it out into a 12 by 12-inch circle. It's okay if the circle isn't perfectly round. In fact, my galette dough usually appears quite rustic and I like it that way. For a perfect circle, simply use a pizza cutter to cut off any uneven edges.
The “king” is represented by the fève, once a fava bean, now a porcelain or plastic figurine, hidden inside the cake. The person who discovers the fève in their serving is declared le roi (the king) or la reine (the queen) and gets to wear the golden paper couronne (crown) that comes with cake.
So where does puff pastry come from. Well it comes from France, where it is called pâte feuilletée. It was invented in 1645 by Claudius Gele, a pastry cook apprentice. He wanted to bake an improved bread for his father who was sick and was on a diet of flour, butter and water.
The simple answer is that a galette is a savoury crêpe. Galettes are made with buckwheat flour instead of usual flour varieties. This gives them a slightly stronger flavour than a normal crêpe or pancake and also means they're gluten free.
Brushing the interior crust of the galette with egg white before adding the filling is a tried and true method for preventing a soggy bottom. The egg white creates a seal that prevents excess moisture from soaking into the crust.
Galette des Rois is eaten to celebrate the Biblical Epiphany. It is a religious feast commemorating the arrival of 'Three Kings' at the manger where Jesus was born.
Brushing the surface of the unbaked crust with beaten egg or egg white mixed with water before adding the filling means that as it bakes, the proteins in the egg will form a moisture barrier over the crust and provide a layer of protection.
And finally, the most frustrating pastry problem of all – the soggy bottom. This normally happens when the oven is not hot enough or the pastry is not baked for long enough. However, it can also be because too much water was added to the dough.
