I stumbled upon this recipe while browsing for vegetarian savory galette recipes and this caught my eye immediately. I loved the idea of using mushrooms and fresh herbs. I tried this recipe out at work and served it as an appetizer. I found that if you cut too small of pieces, the crust falls apart a little bit in the middle, so I suggest cutting it into 8 pieces or less. I also highly recommend letting it cool down so that the whole galette firms up and can truly be a handheld snack.
Swiss Chard and Mushroom Galette barely adapted from Bon Appétit. Serves 4 for dinner or 8 as an appetizer.
Whole Wheat Dough
1 cup all-purpose flour
1 cup whole wheat flour
1 teaspoon kosher salt
3/4 cup (1 1/2 sticks) chilled unsalted butter, cut into pieces
1 tablespoon apple cider vinegar (I didn’t have on hand, so omitted it)
1 cup ricotta (I wanted to add some more, so I used 1 1/2 cups total)
Kosher salt and freshly ground black pepper
3 tablespoons olive oil, divided
4 oz. crimini mushrooms, thinly sliced
1 garlic clove, finely chopped
1 bunch large swiss chard, ribs and stems removed leaves cut into bite size pieces
All-purpose flour (for parchment)
1 large egg, beaten to blend
1 cup mixed fresh tender herbs (such as flat leaf parsley, cilantro, dill and/or chives. Personally, I went with parsley, dill and chives, but only used about 1/2 cup)
1 teaspoon finely grated lemon zest
1 teaspoon fresh lemon juice
Flaky sea salt (such as Maldon)
For the Dough:
1. Pulse all-purpose flour, whole wheat flour, and salt in a food processor to combine. Add butter and pulse until mixture resembles coarse meal with a few pea-size pieces of butter remaining.
2. Transfer mixture to a large bowl; drizzle with vinegar and ¼ cup ice water. Mix with a fork, adding more ice water by the tablespoonful if needed, just until a shaggy dough comes together; lightly knead until no dry spots remain (do not overwork). Pat into a disk and wrap in plastic. Chill at least 2 hours.
3. DO AHEAD: Dough can be made 2 days ahead. Keep chilled.
For the Galette:
1. Preheat oven to 400°. Season ricotta with kosher salt and pepper; set aside.
2. Heat 1 Tbsp. oil in a large skillet over medium-high heat. Add mushrooms; season with kosher salt and pepper and cook, stirring occasionally, until golden brown and crisp, about 5 minutes. Transfer to a small bowl.
3. Heat 1 Tbsp. oil in same skillet over medium heat. Cook garlic, stirring, until fragrant, about 30 seconds. Add half of chard, season with kosher salt and pepper, and cook, tossing, until slightly wilted. Add remaining chard and cook, tossing occasionally, until completely wilted, about 4 minutes. Remove from heat; season with salt and pepper. Set aside.
4. Roll out dough on a lightly floured sheet of parchment to a 14” round about ⅛” thick. Transfer on parchment to a baking sheet. Spread three-fourths of ricotta over dough, leaving a 1½” border. Top with reserved chard, then mushrooms. Dollop remaining ricotta over vegetables. Bring edges of dough up and over filling, overlapping as needed, to create a 1½” border; brush with egg. Bake galette, rotating once, until crust is golden brown and cooked through, 35–40 minutes. Let cool slightly on baking sheet.
5. Toss herbs with lemon juice and remaining 1 Tbsp. oil in a small bowl; season with pepper. Top galette with herbs, zest, and sea salt.
