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. This easy recipe comes from The Weekday Vegetarians, a new cookbook I love by Jenny Rosenstrach.

Every so often, I get a chance to share a recipe from a new book in my library. Today's recipe is from Jenny Rosenstrach's cookbook The Weekday Vegetarians with 100 recipes and a real-life plan for eating less meat. While I do eat and enjoy meat, I incorporate several vegetarian meals each week as part of my Mediterranean lifestyle, so this book is right up my alley!

It was hard to select just one recipe to share with you today, but this rustic, savory galette recipe (or tart) ultimately won. I mean, who doesn't love to eat pie for dinner!

No-Fuss Savory Galette

First off, you can use store-bought pie crust for this recipe--bonus points for ease! The golden, crispy pie shell is filled with a combination of comforting sautéed toppings: mushrooms, leeks, and peas. Jenny's secret ingredient here is a dash of nutritional yeast sprinkled all over the pie crust, adding a nutty, savory, cheesy flavor to the tart without the use of cheese!

It took about 20 minutes to bake in a high-heated oven. I served it for dinner with a side of fresh shirazi salad. Thumbs up all around!

What you'll need to make this galette recipe

You need just a handful of ingredients and spices to make this mushroom-leek galette.

  • Extra virgin olive oil
  • Leeks - You'll need one large or two medium leeks for this recipe.
  • Salt and pepper
  • Dried red pepper flakes
  • Mushrooms - Any variety of mushroom will work as they'll be roughly chopped before cooking.
  • Frozen peas
  • Pie dough - Frozen (thawed) pie dough is fine (if you need a homemade dough, try the one used in my apple galette recipe)
  • Fresh thyme - You'll need just the leaves from a few sprigs of thyme.
  • Nutritional yeast - Creates a cheesy texture and flavor on the crust.
  • Egg - Whisked for an egg wash to make the crust crisp and brown.
  • Flaky sea salt

How to make this savory galette with mushrooms and leeks

Making this savory galette is super simple and requires no pie pan or any special equipment. Here is the step-by-step for how to make it (the print-friendly recipe with measurements follows below):

  • Cook the vegetables and mushrooms. Heat up some olive oil in a large skillet. Add the leeks, salt, pepper and red pepper flakes and cook over medium heat, tossing around, until the leeks are soft. Push them aside and add the mushrooms and a bit more olive oil and cook until they shrivel, then add in fresh thyme and peas and fold everything together and cook for another minute or so (taste and adjust seasoning of course to your liking).

  • Prepare the dough. Roll out the thawed pie crust on a sheet pan lined with parchment paper. Sprinkle the nutrition yeast all over. Be sure to press the flakes into the dough to give the dough a delicious savory flavor.

  • Assemble the galette. Spoon the mushroom and leek filling onto the pie crust and spread it in an even layer, leaving a 1-inch border. Fold the edges over the filling. Brush with the whisked egg and sprinkle with sea salt.

  • Bake. Bake until the crust is golden, 20 to 25 minutes or until the pie crust turns nice and golden brown.

A few tips

If you're making a galette for the first time, here are some things to keep in mind

  • Use a mix of mushrooms. While you can use any type of mushrooms for this mushroom galette, baby portobelo and cremini are two of my favorites. If you can, add more than one type of mushroom for a depth in flavor.
  • Change up the toppings. Feel free to switch up the filling by adding some caramelized onions, spinach, kale, or even small broccoli florets.
  • Leave some filling visible. When folding the crust over, remember that you're just creating a little edge and the center filling should be visible.
  • Do not overfill the crust. When layering 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.

Storage and reheating tips

This mushroom-leek galette is best when enjoyed the same day. However, if you have leftovers, they can be stored in the fridge for up to 3 days.

Reheat your galette in an oven preheated to 350 F, until just warmed through. If necessary, wrap in aluminum foil to prevent burning on the crust. If you try to reheat in the microwave the crust may become soggy so I definitely recommend reheating in the oven.

  5. Camille says:

    Where can you buy nutritional yeast and do you really need it in this recipe

    1. Suzy says:

      Hi, Camille. It is readily available in most grocery stores (at least around me). Check the health food, baking and spice aisles. You can also find it online. It's not an essential ingredient. It just adds another layer of flavor.

  6. Kristen says:

    This looks so delicious! I can't wait to try it.

  7. Marta Prado says:
