Step‑by‑Step Instructions for Mushroom & Onion Galette
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This ensures that your Mushroom and Onion Galette bakes evenly, achieving that perfect golden brown crust. While the oven warms, gather your ingredients and prepare your workspace, including a baking sheet lined with parchment paper for easy cleanup.
Step 2: Sauté the Vegetables
In a large pot, melt a generous amount of butter over medium-high heat. Once melted, add the sliced onions along with the shiitake, white button, and mini portobello mushrooms. Cook for about 10-15 minutes, stirring occasionally, until the vegetables soften and the liquid has mostly evaporated. You’ll want the mixture to be fragrant and only lightly caramelized.
Step 3: Season and Deglaze
After the mushrooms and onions have softened, stir in kosher salt, black pepper, and fresh thyme for depth of flavor. Pour in the white wine and allow the mixture to simmer for an additional 10 minutes. Add minced garlic in the last 2-3 minutes of cooking, just until fragrant. Once done, remove from heat and mix in half the cheese, letting it cool slightly.
Step 4: Prepare the Puff Pastry
Next, take your thawed puff pastry and place it on a floured surface. Using a rolling pin, roll it out into a circle, large enough to fit your baking dish or baking sheet. Carefully transfer the rolled pastry onto your prepared baking sheet, allowing it to rest while you assemble the filling.
Step 5: Assemble the Galette
Spread the creamy boursin cheese evenly in the center of the puff pastry, leaving about an inch of border. Pile the cooled mushroom mixture on top of the cheese, ensuring even distribution. Now, carefully fold the excess pastry over the filling, creating a rustic edge that showcases your savory Mushroom and Onion Galette.
Step 6: Add Toppings and Egg Wash
Sprinkle the remaining cheese over the top of your galette for an extra layer of flavor. To achieve a beautiful golden crust, brush the exposed edges of the pastry with an egg wash made from whisked egg. This gives your galette a delectable finish that is visually enticing as it bakes.
Step 7: Bake to Perfection
Place the assembled galette into your preheated oven and bake for about 40 minutes. Keep an eye on it; you’re looking for a beautifully golden brown crust that’s crispy all around. Once baked, remove it from the oven and let it cool on a rack for approximately 10 minutes before serving.
Step 8: Make the Balsamic Reduction
While the galette cools, prepare the balsamic reduction. In a small skillet, combine balsamic vinegar and sugar, bringing the mixture to a gentle boil. Allow it to simmer for about 10 minutes until it thickens into a syrupy consistency. Stir occasionally to prevent burning, then set aside to cool slightly.
Step 9: Final Touches
To finish, toss fresh arugula with a drizzle of extra virgin olive oil and a pinch of salt for garnish. Once your Mushroom and Onion Galette has cooled, arrange the dressed arugula on top and drizzle the balsamic reduction generously over the entire dish. This adds a pop of color and flavor that elevates the entire experience.
