Rustic Mushroom Galette with Thyme
Rustic mushroom galette with thyme: flaky crust, savory filling, and golden elegance in every bite.
Ingredients
- 1 sheet puff pastry or pie dough (about 9-10 inches), thawed if frozen
- 2 tablespoons olive oil or butter
- 1 large onion, thinly sliced
- 1 lb (450g) mixed mushrooms, sliced
- 3 cloves garlic, minced
- 2 teaspoons fresh thyme leaves (plus extra for garnish)
- 1 teaspoon Dijon mustard (optional)
- ¾ cup (85g) shredded Gruyère or crumbled goat cheese
- Salt and freshly ground black pepper to taste
- 1 egg, beaten (for egg wash)
- Fresh parsley or thyme sprigs for garnish
Instructions
- Preheat and Prep: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper. Roll out the pastry dough into a 12-inch circle on a lightly floured surface.
- Caramelize Onions: Heat olive oil or butter in a large skillet over medium heat. Add sliced onions and cook slowly for 8-10 minutes until soft and golden, stirring occasionally.
- Sauté Mushrooms: Increase heat to medium-high, add sliced mushrooms, and cook for 6-8 minutes until golden brown and moisture has evaporated.
- Add Aromatics: Stir in minced garlic and fresh thyme. Cook for 1-2 minutes until wonderfully fragrant. Season with salt, pepper, and Dijon if using. Remove from heat and cool slightly.
- Assemble the Base: Transfer the dough to the prepared baking sheet. Sprinkle half the cheese in the center, leaving a 2-inch border around the edge.
- Add the Filling: Spoon the mushroom-onion mixture evenly over the cheese. Top with the remaining cheese for extra melty goodness.
- Fold Rustically: Gently fold the dough edges over the filling, pleating as you go to create a beautiful rustic border.
- Egg Wash Magic: Brush the exposed pastry edges with beaten egg. This gives your galette a gorgeous shiny, golden finish.
- Bake to Perfection: Bake for 30-35 minutes until the crust is deep golden brown and the filling is bubbly and aromatic.
- Rest and Serve: Remove from the oven and let the galette rest for 10 minutes. Garnish with fresh thyme or parsley, slice, and serve warm for the best texture and flavor!
Notes
This galette is best enjoyed warm when the crust is crisp and the cheese is gooey. It pairs wonderfully with a crisp green salad and a glass of white wine. Use the best fresh thyme available for maximum aroma. Perfect for make-ahead: assemble earlier in the day and bake just before serving.

Recipe Tips and Tricks
- Keep the dough cold for the flakiest crust—chill it if it warms up.
- Sauté mushrooms on high heat to remove moisture and develop rich flavor.
- Leave a 2-inch border when folding the dough for a beautiful rustic edge.
- Brush the crust with egg wash for a glossy, golden finish.
- Bake on a preheated pizza stone or baking sheet for extra crispiness.
- Let the galette rest 10 minutes before slicing for cleaner cuts.
Ingredients Notes
High-quality puff pastry or homemade pie dough creates the tender, flaky base. Fresh mixed mushrooms (cremini, button, and shiitake) provide deep umami and meaty texture. Caramelized onions add natural sweetness that balances the earthiness.
Fresh thyme is essential for its woodsy, herbal aroma that elevates mushrooms perfectly. Garlic brings savory depth, while Gruyère or goat cheese adds creamy, nutty richness.
A touch of Dijon or balsamic enhances complexity. Use good olive oil or butter for sautéing and season generously to let the simple ingredients shine.
Variations and Substitutions
Add spinach, kale, or leeks for extra greens. Include crumbled goat cheese or feta for tanginess, or sharp cheddar for a bolder flavor. For a meaty version, add cooked bacon or prosciutto.
Swap thyme for rosemary or a mix of fresh herbs. Use wild mushrooms when in season for deeper flavor. Make individual mini galettes for appetizers. For gluten-free, use a gluten-free pie crust.
Add a sprinkle of walnuts or pecans for crunch. Turn it vegan with plant-based cheese, vegan butter, and dairy-free crust. It adapts beautifully to whatever you have on hand.
Storage Options
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a 375°F (190°C) oven for 10-15 minutes to crisp the crust. For longer storage, freeze the unbaked assembled galette on a tray, then wrap tightly for up to 1 month.
Bake directly from frozen, adding 10 extra minutes. Avoid microwaving to preserve texture.
