👩🏽🍳 PRO TIPS
Chill the dough: To achieve a flaky, delicious crust, make sure your butter and water are chilled before incorporating them into your dough. This will help create tiny pockets of steam as the galette bakes, resulting in a wonderfully layered texture.
Season the filling: Don't forget to season your mushroom and onion filling with salt, black pepper, and dry oregano. Proper seasoning will bring out the natural flavors of your ingredients and make your galette truly mouthwatering.
Roll the dough evenly: When rolling out your dough, aim for a thickness of around six to seven inches. This will help guarantee even baking and prevent the dough from becoming too thin or breaking when you add the filling.
Layer the ingredients: Start with a generous layer of your chosen cheese, followed by the mushroom and onion filling. This not only adds depth of flavor but also helps to keep the crust from getting soggy.
Watch Your Baking Time: After initially baking the galette for twenty minutes, you'll want to add an egg to the center and bake for ten more minutes. Keep a close eye on your oven during this time to prevent overcooking.
📋 VARIATIONS
Add Some Heat: For those who enjoy a bit of spice, try adding half a teaspoon of crushed red pepper flakes to the mushroom filling. This will add a subtle heat that enhances the earthy flavors of the mushrooms and onions.
Boost the Herbs: If you love the taste of herbs, add a teaspoon of fresh thyme leaves to the mushroom filling. The thyme adds a wonderful earthy flavor that compliments the mushrooms perfectly.
More Cheese, Please: For the cheese lovers out there, consider doubling the amount of cheese in the filling. You can even try a blend of different cheeses like Gruyere and Parmesan for a more complex flavor.
