Steam curls from the skillet, carrying a nutty toasted scent as tender mushroom slices mingle with gooey goat cheese beneath flaky folds. That’s the first memory I have of my own Mushroom Galette trials—after three rounds, I mastered golden edges that crackle just so and a filling rich with earthy warmth. Today, I’m sharing those discoveries, from dough quirks to skillet secrets.

Why You’ll Love Mushroom Galette

  • A symphony of textures: crisp crust giving way to a silky smooth, savory center
  • Hands-on dough work that’s therapeutic yet straightforward
  • Customizable filling—swap cheeses, herbs or mushrooms to suit your pantry
  • A rustic dish with roots in French country cooking, now a weeknight favorite

A Little Background

During early autumn I dedicated a drizzly weekend to perfecting this tart-like Mushroom Galette. My kitchen counter was speckled with flour and thyme leaves as I tested butter quantities for that just-right flakiness. The first batch sank in the center, but by attempt three, I’d nailed a sturdy, golden rim that cradles the filling without a single leak.

Personal Testing Note (Prep): I found chilling the dough a full 30 minutes—rather than the suggested 20—yields a firmer, easier-to-roll disk that resists sticking.

Key Ingredients for Mushroom Galette

  • All-purpose flour: Forms a sturdy base; swap half for whole wheat for a nuttier crust
  • Unsalted butter: Cold cubes create those signature flaky layers
  • Mixed mushrooms: I prefer cremini and shiitake—each slice adds depth
  • Goat cheese & Parmesan: Creamy tang meets sharp umami for balance
  • Fresh thyme: Woody fragrance that bridges dough and filling

How to Make Mushroom Galette

  1. In a bowl, whisk 1¼ cups all-purpose flour, 2 tsp thyme leaves and ½ tsp salt. Cut in 6 tbsp cold butter until pea-sized crumbs form.
  2. Add 3–4 tbsp ice water, stirring until dough just comes together. Shape into a 6-inch disk, wrap, chill for 30 minutes.
  3. Meanwhile, heat 2 tbsp butter and 1 tbsp olive oil in a skillet over medium. Add 1 lb sliced mushrooms, salt and pepper; cook, stirring, until liquid evaporates (8–10 minutes).
  4. Stir in 2 minced garlic cloves and ½ tsp thyme; cook 1 minute. Remove from heat, blend in 3 oz goat cheese and ½ cup Parmesan. Let cool slightly.
  5. Preheat oven to 375°F (190°C) and line a baking sheet with parchment.
  6. On a floured surface, roll dough into a 12-inch circle. Transfer to prepared sheet.
  7. Spoon filling into center, leaving a 2-inch border. Fold edges over, pleating as you go.
  8. Brush crust with 1 beaten egg and sprinkle flaky sea salt. Bake 40–45 minutes until crust is golden and filling bubbles.
  9. Let rest 5 minutes before slicing; the edges will crackle as they cool.

Pro Tips & Troubleshooting

  • For extra flakiness, freeze butter cubes 10 minutes before cutting in.
  • If the filling leaks, your dough was too warm—chill it again for 10 minutes before shaping.
  • Add a handful of baby spinach or a smear of pesto for a seasonal twist.
  • To halve the recipe, divide all ingredients and use a smaller 9-inch rolling circle.

Storage & Make-Ahead Guide

Allow galette to cool, then cover and refrigerate within two hours (max). Store in an airtight container for up to 3 days; reheat at 350°F for 10 minutes. For longer keeping, freeze on a tray until firm, then wrap in foil for up to 1 month—thaw overnight in fridge before reheating. Always discard leftover slices after 4 days for safety.

Personal Testing Note (Storage): I found that reheating on a wire rack preserves crust crispness better than a plate.

Serving Suggestions

Slice alongside a tangy arugula salad for brightness, or serve with a drizzle of aged balsamic and a glass of crisp Chardonnay. Leftovers also shine with a fried egg perched on top for brunch.

Frequently Asked Questions

  • How do you keep the galette crust from getting soggy? Chill the assembled galette 10 minutes before baking and bake on a parchment-lined, preheated sheet to encourage immediate crisping.
  • Can I prepare the galette dough ahead of time? Yes—prepare and chill the dough up to 2 days in advance, wrapped airtight.
  • What are the best mushrooms for a galette? Cremini, shiitake or oyster mushrooms hold shape and develop a deep, nutty flavor when sautéed.
  • How do you reheat leftover galette? Warm slices at 350°F (175°C) for about 8–10 minutes on a wire rack to revive the crisp crust.
  • Can I freeze a fully baked galette? You can—freeze wrapped in foil for up to one month; thaw overnight in the fridge before reheating.
  • What’s the difference between a tart and a galette? A tart uses a pan and uniform shape, while a galette is free-form with rustic folded edges.

Final Thoughts

Mushroom Galette is one of my go-to dishes when I want rustic flair with minimal fuss. I love pairing it with a simple green salad and sharing slices with friends around the table. Give it a try, and let me know how your edges flake and flavors sing!

Ingredients

Dough

  • 1.25 cups all-purpose flour
  • 2 tsp fresh thyme leaves
  • 0.5 tsp salt
  • 6 tbsp cold unsalted butter cubed
  • 3 tbsp ice water plus up to 1 tbsp more if needed
  • 1 egg beaten, for egg wash
  • 1 pinch flaky sea salt for finishing

Filling

  • 2 tbsp unsalted butter
  • 1 tbsp olive oil
  • 1 lb mixed mushrooms sliced
  • 2 cloves garlic minced
  • 0.5 tsp fresh thyme leaves
  • 3 oz goat cheese
  • 0.5 cup grated Parmesan
  • salt and pepper to taste

Instructions

Dough

  • In a bowl, whisk together flour, thyme leaves and salt. Cut in cold butter until mixture resembles coarse crumbs.
  • Add ice water, 1 tbsp at a time, stirring until dough holds together.
  • Shape dough into a 6-inch disk, wrap in plastic and chill for 30 minutes.
  • Preheat oven to 375°F (190°C) and line a baking sheet with parchment.

Filling

  • In a skillet, heat butter and olive oil over medium heat.
  • Add mushrooms, season, and cook until liquid evaporates, about 8–10 minutes.
  • Stir in garlic and thyme; cook 1 minute more.
  • Remove from heat and fold in goat cheese and Parmesan. Let cool slightly.
  • Roll chilled dough into a 12-inch circle on a floured surface and transfer to prepared sheet.
  • Spoon filling into center, leaving a 2-inch border.
  • Fold edges over the filling, pleating as needed.
  • Brush crust with egg wash and sprinkle with flaky sea salt.
  • Bake 40–45 minutes until crust is golden and filling bubbles.
  • Let rest 5 minutes before slicing.

Notes

Chilling the dough for 30 minutes makes it easier to roll and helps the crust stay flaky.
Reheat slices at 350°F for 8–10 minutes on a wire rack to revive the crunch.
Assemble and freeze the dough up to 1 month; thaw overnight before baking.
