Ingredients & Preparation Notes

- Salt: Enhances the flavors of the dough and filling.
- Cold unsalted butter: Essential for a flaky crust. Keep it cold to avoid melting into the dough.
- Ice water: Helps bind the dough without developing too much gluten.
- Olive oil: Used to sauté the onions and mushrooms, adding a subtle flavor.
- Onion: Thinly slice for even caramelization, which brings out their sweetness.
- Mushrooms: Choose a variety like cremini or button for their earthy flavor and texture.
- Sausage: Use a high-quality sausage; remove from casings for even distribution in the filling.
- Fresh thyme: Adds a subtle herbaceous note that complements the other flavors.
- Gruyère cheese: Its nutty flavor melts beautifully into the filling.
- Egg: Used for the egg wash to give the crust a golden, glossy finish.
- Salt and pepper: Season to taste to balance the flavors.
For substitutions, consider using a gluten-free flour blend for the dough, and a dairy-free cheese alternative if needed.
Professional Tips & Techniques
- Dough Handling: Keep the dough cold to ensure a flaky texture. If it becomes too warm, chill it again before rolling.
- Caramelization: Cook onions slowly over low heat to achieve a deep caramel color and sweet flavor. This can take up to 20 minutes, but it’s worth the wait.
- Sausage Cooking: Break up the sausage into small pieces while cooking to ensure even distribution throughout the galette.
- Baking Temperature: Preheat your oven to 400°F (200°C) for a golden, crisp crust. Check the galette at 30 minutes; it may need a few more minutes depending on your oven.
- Visual Cues: The galette is done when the crust is golden brown and the filling is bubbly. A slight browning of the cheese on top is a good sign.
Recipe Variations
- Vegetarian Option: Substitute the sausage with a mix of lentils and sautéed vegetables for a hearty meat-free version.
- Gluten-Free Adaptation: Use a gluten-free flour blend to make the crust suitable for those with gluten sensitivities.
- Different Meats: Try using ground beef or turkey instead of sausage for a different flavor profile.
- Cheese Varieties: Experiment with different cheeses like cheddar, feta, or goat cheese to change the taste.
- Seasonal Vegetables: In spring, add asparagus or in summer, try zucchini to incorporate seasonal produce.
- Herb Variations: Swap thyme for rosemary or sage to alter the herbaceous notes.
- Spicy Kick: Add a pinch of red pepper flakes to the sausage for a spicy twist.
- Sweet and Savory: Include a touch of balsamic vinegar to the onions for a sweet and tangy flavor.
Serving Suggestions
- As a Main Course: Serve the galette with a simple green salad dressed with vinaigrette to balance the richness.
- For a Brunch: Pair it with fresh fruit and mimosas for a delightful brunch spread.
- At a Dinner Party: Slice the galette into wedges and serve as an appetizer or part of a buffet.
- With Soup: Accompany it with a bowl of hearty vegetable soup for a comforting meal.
- Presentation Tips: Garnish with fresh herbs like parsley or additional thyme for a pop of color.
- Pairing Suggestions: A glass of red wine, such as Pinot Noir, complements the savory flavors beautifully.

Sausage Galette with Caramelized Onion and Mushroom
Ingredients
Equipment
Method
- In a large bowl, combine 1.5 cups all-purpose flour and 0.5 tsp salt. Add 0.5 cup cold unsalted butter and use a pastry cutter or your fingers to blend until the mixture resembles coarse crumbs. Gradually add 0.25 cup ice water, mixing until the dough comes together. Form into a disk, wrap in plastic, and refrigerate for at least 30 minutes.
- Preheat your oven to 400°F (200°C). Heat 1 tbsp olive oil in a skillet over medium heat. Add 1 large onion, thinly sliced, and cook, stirring occasionally, until caramelized, about 20 minutes. Remove onions and set aside.
- In the same skillet, add 8 oz mushrooms, sliced, and cook until browned and tender, about 10 minutes. Remove and set aside with the onions.
- Add 12 oz sausage, removed from casings, to the skillet. Cook until browned and cooked through, breaking it up with a spoon. Drain excess fat if necessary. Stir in 1 tsp fresh thyme, salt, and pepper to taste.
- On a lightly floured surface, roll out the chilled dough into a 12-inch circle. Transfer to a parchment-lined baking sheet. Spread the caramelized onions evenly over the dough, leaving a 2-inch border. Top with the mushrooms and sausage. Sprinkle with 0.5 cup Gruyère cheese.
- Fold the edges of the dough over the filling, pleating as you go. Brush the crust with 1 large egg, beaten, for an egg wash. Bake for 30-35 minutes, or until the crust is golden brown and the filling is hot and bubbly. Let cool slightly before serving.
