French Savory Buckwheat Galettes with Mushrooms

Method

1. Mix and rest the batter

   

   Whisk 200 g of buckwheat flour and 4 g of fine sea salt in a large bowl. Gradually whisk in 500 ml of cool water, starting with a small splash to make a smooth paste before adding the rest. Continue whisking until the batter is fluid and free of dry pockets; it should pour in a thin ribbon. Let it rest at room temperature for 40 minutes, then whisk again before cooking.

2. Prepare the mushroom filling

   Wipe 500 g of cremini mushrooms clean and slice them about 5 mm thick. Finely chop 100 g of shallots, mince 2 garlic cloves, strip the leaves from 5 g of fresh thyme sprigs, grate 120 g of Gruyère cheese, and chop 10 g of fresh parsley. Keep the cheese and parsley separate from the raw vegetables so they are ready when the galettes reach the pan.

3. Soften the aromatics

   Heat 30 ml of olive oil in a wide skillet over medium heat. Add 100 g of shallots and cook, stirring often, for about 3 minutes until softened and translucent at the edges. Add 2 garlic cloves and stir just until fragrant, keeping the garlic pale.

4. Brown the mushrooms

   

   Raise the heat to medium-high and add 500 g of cremini mushrooms. Spread them across the skillet and leave them undisturbed briefly so they begin to color, then cook, stirring every minute or two, for 8 to 10 minutes. Start checking at 8 minutes; the mushrooms are ready when their released liquid has evaporated and the edges are well browned. Season with 1 g of black pepper.

5. Finish the creamy filling

   

   Reduce the heat to low. Stir in 80 g of crème fraîche, 15 g of Dijon mustard, and 5 g of fresh thyme sprigs until the mushrooms are lightly coated and the sauce clings rather than pools. Remove the skillet from the heat and taste; the Gruyère added later will bring additional saltiness.

6. Cook the galettes

   

   For the default 4 servings, use a 10-inch (25-cm) nonstick crêpe pan or low-sided skillet to make 8 galettes, 2 per serving. Heat the pan over medium-high heat until a drop of batter sizzles on contact. Melt 20 g of unsalted butter and use just enough to leave a thin film on the pan before each galette. Stir the batter, then pour in about 1/3 cup (80 ml) and immediately tilt and rotate the pan to cover the base in a thin, even layer. Cook for 1 1/2 to 2 minutes, starting the timer for the first check, until the surface has lost its wet sheen, the edges lift easily, and the underside is mottled brown. Flip and cook the second side for about 15 to 30 seconds, until set and lightly spotted. Stir the batter before each new galette and adjust the heat if the edges darken before the center sets.

7. Fill and fold the galettes

   

   Return one galette to the pan with its paler side facing down. Divide 120 g of Gruyère cheese and the mushroom filling evenly among the cooked galettes; at the default 4 servings, this is 8 galettes, or 2 per serving. Keep each portion in the center so the edges remain flexible. Heat for 1 to 2 minutes, starting the timer for the first check, until the cheese softens and the filling is hot. Fold four sides inward to make a square with an open center, pressing each fold gently so it holds its shape.

8. Finish and serve

   Transfer the filled galettes to plates while the edges are crisp and the centers are hot. Scatter 10 g of fresh parsley over the mushrooms and serve immediately, with a knife and fork for cutting through the folded edges and creamy filling.

Smart Substitutions

• No Gruyère? Use Comté, Emmental, or a firm Alpine-style cheese that melts smoothly.
• No crème fraîche? Use full-fat sour cream and keep the heat low so the filling stays smooth.
• No cremini mushrooms? Use white button mushrooms or a mix of oyster and shiitake mushrooms, cutting larger pieces to a similar thickness.
• Prefer a dairy-free filling? Cook the galettes with olive oil, use a thick unsweetened plant-based cultured cream, and replace the cheese with a savory plant-based melting cheese.

Tips and Variations

• Give the pan enough time to preheat; a lukewarm surface makes the batter stick before it can set.
• Stir the batter before every galette because buckwheat flour settles quickly at the bottom of the bowl.
• Keep the mushroom layer modest so the folded edges stay crisp and the galette remains easy to cut.

What Went Wrong?

• Galette tears when flipped Cook the first side until the entire surface looks dry and the edges release cleanly before sliding the spatula underneath.
• Galette is thick or rubbery Whisk in a small splash of water and rotate the pan immediately after pouring so the batter forms a thin layer.
• Mushroom filling is watery Keep cooking over medium-high heat until the released liquid has evaporated before adding the crème fraîche.
• Cheese does not melt Lower the heat slightly, cover the pan briefly, and remove the cover as soon as the cheese softens so the galette does not steam excessively.
