Ingredients You’ll Need
The magic of this galette lies in its simplicity; each ingredient plays a vital role in building those rich, layered flavors and giving the dish its inviting texture and color. Here’s a complete list that you’ll find both straightforward and essential for this recipe.
- 1 cup all-purpose flour: Provides the perfect base for a sturdy yet tender crust.
- 1/2 cup cornmeal: Adds a lovely crunch and subtle nuttiness to the crust.
- 1 teaspoon kosher salt: Enhances all the flavors, especially in the dough and filling.
- 1 teaspoon black pepper: Gives a gentle spicy kick throughout.
- 1 stick butter, very cold: The secret to a flaky, buttery crust that melts in your mouth.
- 2 eggs, divided: One for the dough to bind it together, and one to brush over the crust for a beautiful golden finish.
- Ice water: Keeps the dough cool to help maintain that flaky texture.
- 1 tablespoon olive oil: Adds richness to the sautéed filling.
- 3 garlic cloves, minced: Brings a fragrant aroma and depth to the mushrooms and spinach.
- 10 ounces mushrooms (shiitake and baby bella recommended): Offer meaty, earthy flavor and texture.
- 5 ounces baby spinach: Adds freshness, color, and nutrients.
- 1 kosher teaspoon salt: Seasoning for the filling to bring out the greens and mushrooms.
- 16 ounces mozzarella, sliced into 1/4 inch rounds: Melted, gooey, and perfectly mild cheese.
- 1 cup shredded parmesan: Adds a sharp, salty punch that balances the creaminess of mozzarella.
- Optional fresh thyme or rosemary: Perfect aromatic herbs to finish and garnish.
How to Make Spinach Mushroom Galette Recipe
Step 1: Prepare the Crust
Start by combining the flour, cornmeal, salt, and pepper. You can do this either in a food processor or by hand in a bowl. The key here is to cut the cold butter into the dry ingredients until it resembles pea-sized pieces—this is what creates all those flaky layers in your crust. Next, add one egg and a tablespoon of ice water, pulsing or mixing patiently until the dough just comes together. It might take a few tablespoons of water, but be careful not to over-hydrate. Once combined, knead briefly, form a disk, wrap it up, and chill in the fridge for 30 minutes to let the butter firm back up.
Step 2: Prepare the Filling
This is where the galette comes alive. Warm olive oil in a pan and gently sauté the minced garlic until fragrant, about 30 seconds. Toss in the mushrooms and cook until they start to soften and release their lovely juices. Gradually add the spinach in handfuls, letting it wilt down perfectly. Season with kosher salt, stir it one last time, and take it off the heat. This filling, bursting with umami and brightness, will be the heart of your galette.
Step 3: Roll Out the Dough and Assemble
Preheat your oven to 375°F (190°C). On a floured surface, roll your chilled dough into a circle about 1/4 inch thick. Transfer it to a baking sheet for easy handling. Arrange mozzarella slices around the dough but leave a 2-inch border—this border will be folded over to cradle the filling. Spread half your mushroom and spinach mixture over the cheese, sprinkle half the parmesan, then layer the rest of the filling and cheese before folding the edges inward. Brush the crust with the beaten second egg for that beautiful golden hue after baking. If you like, tuck a few rosemary leaves into the crust edges for fragrance and beauty.
Step 4: Bake to Perfection
Bake your gorgeous galette for 45 minutes or until the crust is golden and crisp. The aroma will be irresistible. Once out of the oven, let it cool a few minutes so the filling sets a bit, then slice and serve your masterpiece.
