Savory Mushroom and Leek Galette

Made with pie crust and a handful of fresh ingredients, this Savory Mushroom Galette with Leeks is a delicious vegetarian dish that’s perfect served for dinner (with your favorite salad) or as an appetizer for a small crowd. Making this savory galette is super simple and requires no pie pan or any special equipment.

While you can use any type of mushrooms for this galette, baby portobello and cremini are two great choices—and it was what we used. If you can, add more than one type of mushroom for a depth in flavor. And if you are feeling a bit adventurous, feel free to switch up the filling by adding some caramelized onions, spinach, kale, or even small broccoli florets. Personally, we thought it was great as is!

When folding the crust over, remember that you’re just creating a little edge and the center filling should be visible. With the filling on the pie dough, be sure to leave an edge of 1″ or so without any filling, to later fold the dough over. Be sure to spread the filling evenly as well for better baking.

Nutritional yeast was new to me (but not The Hubs). It, affectionately called “nooch” is a deactivated form of Saccharomyces cerevisiae, commonly known as baker’s or brewer’s yeast. The key word here is deactivated. Don’t try putting nutritional yeast in your next loaf of bread—it won’t make it rise! This funky, flaky yellow powder seems like a totally out-there ingredient, but today, it is used for making “cheesy” vegan sauces and dips, punching up popcorn, and adding savory flavor to soups, scrambles, and more. Who knew?

But the reasons to eat nooch go beyond its health benefits. Its flavor is nutty and savory, making it a delicious addition to all sorts of dishes. Most often, it’s used to add cheesy flavor to plant-based recipes like Vegan Mac and Cheese, creating the umami that Parmesan or cheddar cheese would add.

Between the two of us, we ate 3/4 of the galette with a side salad for dinner. If going to make as an appetizer, we suggest cutting the filling ingredients in half, otherwise it will be a bit wonky to try to eat.

  • Difficulty: easy
  • Print


  • 4 Tbsp. extra virgin olive oil
  • 1 large leek (or two medium leeks, white parts only, finely chopped, about 3 cups)
  • Kosher salt and black pepper
  • ½ tsp. dried red pepper flakes
  • 1 lb. mushrooms (any kind, stemmed, cleaned, and roughly chopped, about 7 cups)
  • 3 fresh thyme sprigs, leaves only
  • ⅓ cup frozen peas

  1. Preheat the oven to 425°F. Line a sheet pan with parchment paper

  4. Stir in the thyme and peas and cook another minute, folding in the leeks.
  5. Place the pie dough on the prepared sheet pan and sprinkle the nutritional yeast all over it, pressing the flakes into the dough with your fingers or a rolling pin

  7. Brush the dough with the whisked egg and sprinkle with the sea salt.
  8. Bake in the heated oven until the crust is golden, 20 to 25 minutes.
  9. Let cool about 5 minutes and then cut into 8 slices. Serve immediately.
