Sometimes, the most memorable dishes from our past aren’t elaborate holiday feasts or recipes passed down through generations. Instead, they’re based on the flavors of childhood – for inspiration for this dish came from a like a plate of perfectly fried zucchini. While many people associate zucchinis with summer, they remain a staple in our kitchens throughout the year, making them a fantastic choice for comforting dishes. Today, I’m sharing a no-nonsense recipe that takes this versatile vegetable and turns it into a delicious and satisfying treat: a savory and seasonal zucchini galette, made with a gluten-free crust, caramelized onions, Gruyere cheese, and beautifully sliced zucchini.

It’s a dish that will keep you cozy on chilly night.

For me, this dish holds a special place, evoking cherished memories of the delicious tastes of youth. It’s a taste that I’ve carried with me through the years, and it recently sparked a culinary journey that led to something truly special. Join me as I share a unique creation born from my love for the delicate and savory taste of zucchini.

Ingredients

These ingredients come together to create a gluten-free zucchini galette that’s both flavorful and suitable for those with gluten sensitivities.

Gluten-Free Dough
  • Follow the instructions found here for my gluten free pie dough recipe.
Zucchini
  • Zucchinis are a summer and early fall squash with tender, edible skin. They are mild in flavor and have a slightly sweet, nutty taste. You thinly slice the zucchinis and arrange them on top of the galette, creating a delicious and visually appealing layer.
Olive Oil
  • Use olive oil to sauté and caramelize the onions. It adds a subtle fruity and earthy flavor to the dish and helps soften and sweeten the onions.
Unsalted Butter
  • Unsalted butter lends a creamy and rich quality to the caramelized onions.
Onions
  • Use sliced and caramelized to bring a sweet, rich, and savory flavor to the galette. The slow cooking process turns them soft and golden brown, enhancing their natural sweetness.
Fresh Thyme, Sage, or Herbs de Provence
  • Aromatic herbs are a wonderful addition, providing a burst of flavor and aroma. Thyme is earthy, and slightly lemony note. Sage is warm, and savory. Herbs de Provence is a blend of herbs like rosemary, marjoram, and lavender, offering a fragrant and harmonious flavor profile. When caramelized with the onions, they infuse a rich, savory essence that elevates the overall taste of the galette. Sprinkling some fresh herbs on top of the assembled galette enhances its visual appeal and introduces a pop of freshness.
Gruyere Cheese
  • A Swiss cheese known for its nutty and fruity flavor, melts into a creamy texture that enhances dishes like quiches, galettes, and fondues. In this recipe, it adds a cheesy richness to the filling.
Kalamata Olives
  • Chefs and home cooks alive prize Kalamata olives for their distinctive flavor and texture. These dark, almond-shaped olives have a briny, slightly tangy taste with a hint of fruitiness. When chopped in half or quarters and placed on top of the zucchini in the galette, they contribute a delightful burst of salty, umami goodness that complements the other ingredients. Their brininess adds depth and contrast to the dish, creating a harmonious balance of flavors.11. Salt and Pepper:
Salt and Pepper
  • I use salt and pepper to enhance the overall flavor of the galette. They add a necessary savory element to balance the sweetness of the caramelized onions and zucchini.

Equipment

Essential Equipment to Prepare the Gluten-Free Zucchini Galette Recipe:

Food Processor (optional)
  • A food processor is handy for making the gluten-free dough quickly and efficiently. However, you can also mix the dough by hand if you don’t have a food processor.

Rolling Pin

  • You’ll need a rolling pin to roll out the dough into a circle of the desired size. This will help create the crust for your galette.

Mixing Bowls

  • Use mixing bowls to combine and mix various ingredients throughout the recipe, including the dough and filling components.

Measuring Cups and Spoons

  • Measuring cups are essential for accurately measuring ingredients like flour, water, and grated cheese. Measuring spoons help you measure smaller quantities of ingredients like salt, xanthan gum, sugar, and herbs.

Skillet

  • Use a skillet or frying pan to caramelizing the onions. You’ll use it to melt butter, cook the onions until they become soft and caramelized, and add herbs and sugar for flavor.
Rimmed Baking Sheet
  • A rimmed baking sheet is essential for baking the galette in the oven. It provides a flat surface for the galette to cook evenly.
Parchment Paper
  • I use parchment paper is to line the baking sheet and prevent the galette from sticking. It also makes it easier to transfer the galette in and out of the oven.
Knife and Cutting Board
  • A knife and cutting board are essential for slicing the zucchinis thinly and chopping the Kalamata olives if they aren’t pre-pitted and sliced.
Box Grater (optional)
  • If you prefer using whole blocks of cheese, you can grate Emmentaler cheese with a box grater, which is a key ingredient in the filling of the Gluten-Free Zucchini Galette. However, if you choose the convenience of pre-grated cheese, you can skip this step and proceed with the pre-grated cheese of your choice. 
Brush or Pastry Brush
  • A brush or pastry brush is handy for applying the egg yolk wash to the edges of the galette, which gives it a beautiful golden finish.
Oven
  • You’ll use a conventional oven to bake the galette to perfection.
Mandolin Slicer (Optional for Zucchini)
  • A mandolin slicer can be used to achieve even and consistent 1/8-inch rounds when slicing the zucchinis for the galette.
Cooling Rack (Optional)
  • While not essential, a cooling rack can help cool the galette evenly once it’s removed from the oven. Just don’t place a hot pan directly on a heat sensitive counter.
Pastry Brush (Optional)
  • A pastry brush is used to apply the egg yolk wash to the edges of the galette for a golden finish. You can also use a clean brush or your fingers for this step.A food processor is handy for making the gluten-free dough quickly and efficiently. However, you can also mix the dough by hand if you don’t have a food processor.

These are the basic kitchen tools you’ll need to make the Gluten-Free Zucchini Galette. Make sure to have them ready before you start cooking for a smooth and enjoyable cooking experience.

Substitutions

Remember to consider any dietary restrictions or personal preferences when making substitutions. The key is to adapt the recipe to your needs while still maintaining the overall structure and flavors of the galette. Enjoy your customized zucchini galette!

These ingredients have easy substitutions.

Unsalted Butter
  • If you’re dairy-free, you can substitute cold dairy-free margarine or a vegan butter alternative for the unsalted butter used in the dough. Make sure it’s cold and solid when you use it. Additionally, if you don’t have unsalted butter, you can use salted butter, just reduce the salt in the dough by ½.
Gruyère Cheese
  • If you prefer a different cheese or have dietary restrictions, you can substitute Gruyère with other mild, meltable cheeses like Emmental, Swiss, or a dairy-free cheese if you’re vegan.
Egg Yolk (for egg wash)
  • If you’re vegan or allergic to eggs, you can use dairy-free milk, like almond or soy milk, as a wash to give the crust a golden color.
Olive Oil
  • If you don’t have olive oil or prefer a different flavor, you can use vegetable oil, canola oil, or even melted coconut oil. My go-to when I don’t want to use olive oil is avocado oil as it has a neutral flavor, high heating temperature and is heart healthy.
Onions
  • If you’re not a fan of onions or have dietary restrictions, you can use shallots, leeks, or scallions as a substitute. They will provide a similar caramelized flavor.
Zucchinis
  • While zucchinis are the star of this recipe, you can experiment with other thinly sliced vegetables like summer squash, yellow squash, or even thinly sliced sweet potatoes for a different twist.
Seasonings
  • Feel free to adjust the seasonings according to your taste. You can add herbs like thyme, rosemary, or basil to enhance the flavor.

Ingredients

Gluten Free Dough

Zucchini Filling

Instructions

Prepare the Gluten-Free Crust

  1. Prepare a single gluten-free pie crust according to the recipe found here

Caramelize the Onions

  1. Heat 1 tablespoon olive oil in a skillet over medium-low heat.

  2. Melt 1 tablespoon of butter.

  3. Add the thinly sliced onions, herbs, and cook, stirring occasionally, until they turn a deep golden brown and become caramelized, about 30-40 minutes. Watch the heat to ensure you do not burn the onions. Lower the heat if necessary. Season with salt and pepper to taste. Set aside to cool.

Prepare the Zucchini (While Caramelizing Onions)

  1. While the onions are caramelizing in the skillet, slice the zucchinis into thin 1/8-inch rounds. You can use a knife or a mandoline slicer for even thickness.

  2. Place the sliced zucchini rounds in a mixing bowl and toss them with 1 teaspoon of kosher salt. Ensure that the salt is evenly distributed among the zucchini slices.

  3. Allow the salted zucchini to rest in the bowl for approximately 30 minutes. This resting period will draw out excess moisture from the zucchini, helping to prevent a soggy galette. After 30 minutes, drain the zucchini slices in a colander and gently press them with a clean kitchen towel or paper towels to remove any excess moisture before arranging them on the galette. This step ensures that the zucchini slices are properly prepared to maintain the galette's texture and prevent excess moisture, resulting in a delicious and perfectly cooked Gluten-Free Zucchini Galette.

Assemble the Galette

    • Preheat your oven to 375°F (190°C).
    • On a sheet of parchment paper, roll out the chilled dough into a rough circle, about 14 inches in diameter.
    • Transfer the dough on the parchment to a rimmed baking sheet. Chill in the refrigerator for 15 minutes.
    • Leaving a 2-inch border, spread the caramelized onions evenly over the dough.
    • Sprinkle 2/3 of the shredded Emmental or Gruyere cheese over the onions.
    • Arrange the thinly sliced zucchini in an overlapping pattern on top of the cheese.
    • Cut each olive in half or quarters and arrange on top of the zucchini layer
    • Sprinkle the remaining cheese over the zucchini.
    • Lightly season with salt and pepper to taste.
    • Carefully fold the edges of the dough over the filling, creating pleats as you go.
    • Brush the folded edges of the galette with the egg yolk (or cream) wash for a golden finish.
    • Sprinkle with additional herbs or cracked pepper.
    • Bake in the preheated oven for 30-35 minutes, or until the crust is golden brown and the zucchini is tender.
    • Remove the galette from the oven and let it cool for a few minutes.
    • Slice, serve, and savor the hearty flavors of fall with this straightforward and gluten-free zucchini galette.

Note

  • Gluten-Free Flour: I use a blend that I have modified, based on a recipe from ATK, The ATK recipe can be found in this cookbook. That blend does not contain xanthan gum, so I add it separately depending on the recipe.
  • If you are using a gluten-free blend that is not listed as a one-to-one replacement, it is important to weigh the flour. My gluten-free flour blend weighs 128 grams.
  • There are, however, many commercially available gluten-free flour blends at your local grocer or online. Here are several that are available from Amazon:
  • All of these flours do contain xanthan gum. So omit the extra xanthan if using one of these blends. All of the manufacturers promote these products as a one-to-one replacement.
  • Resting the batter: after mixing the dough, let it chill in the refrigerator for one hour. This allows the gluten-free flour to fully hydrate creating strength and eliminating a gritty texture.
  • These cookies are best enjoyed in 3 – 5 days. They are on the dryer side and are great with coffee, tea, or red wine.

Frequently Asked Questions: Feel free to ask any additional questions you may have about the Gluten-Free Zucchini Galette recipe, and I'll be happy to assist!

Expand All:
Can I use regular all-purpose flour instead of gluten-free flour for the dough?

Yes, you can use regular all-purpose flour if you don't have dietary restrictions. The dough will have a different texture and flavor, but it will work just fine.

What is the purpose of xanthan gum in gluten-free baking?

Xanthan gum is a common additive in gluten-free baking. It helps mimic the binding and elasticity properties of gluten, improving the texture and structure of gluten-free baked goods.

Can I make the dough ahead of time and store it in the fridge?

Yes, you can prepare the dough in advance. After shaping it into a disk, wrap it tightly in plastic wrap and refrigerate it for up to 2 days before using it in the recipe.

I don't have Gruyère cheese. What other cheeses can I use?

You can substitute Gruyère with similar mild and meltable cheeses like Emmental, Swiss, or even mozzarella. If you have dietary restrictions, consider using dairy-free cheese alternatives.

Why should I salt and rest the zucchini before placing it on the galette?

Salting and resting the zucchini is a crucial step to ensure the success of your Gluten-Free Zucchini Galette. When you slice the zucchini into thin rounds and toss them with salt, you initiate a process called "osmosis." During this resting period, the salt draws out excess moisture from the zucchini, which is essential for two reasons:

  1. It Prevents Sogginess: Zucchini contains a high water content, and if it's not properly prepared, it can release excess moisture while baking, leading to a soggy galette crust. Salting and resting the zucchini helps remove this excess liquid, ensuring a crisp, flaky crust.
  2. It Enhances Flavor: The salt not only extracts moisture but also seasons the zucchini from the inside out. This step enhances the zucchini's flavor, making it more savory and delicious in the final dish.

I'm vegan. Can I make this galette without dairy and eggs? Yes, you can make this galette vegan-friendly. Use dairy-free margarine or vegan butter for the dough, skip the egg yolk wash (use a dairy-free milk wash instead), and opt for dairy-free or vegan cheese alternatives.

Yes, you can make this galette vegan-friendly. Use dairy-free margarine or vegan butter for the dough, skip the egg yolk wash (use a dairy-free milk wash instead), and opt for dairy-free or vegan cheese alternatives.

How do I store leftover galette?

To store leftovers, wrap the galette in aluminum foil or plastic wrap and refrigerate for up to 2-3 days. Reheat in a preheated oven at 350°F (175°C) for about 10-15 minutes until warmed through.

Can I freeze the galette for later?

Yes, you can freeze the galette. Wrap it tightly in plastic wrap and aluminum foil or place it in an airtight container before freezing. It should be good for up to 2-3 months. Thaw in the refrigerator before reheating.

Can I customize the fillings in this galette?

Absolutely! You can get creative with the fillings. Try adding sautéed mushrooms, spinach, roasted red peppers, or different herbs and spices to suit your taste.

What's the best way to reheat a slice of galette?

To reheat a slice, place it on a baking sheet and warm it in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until it's heated through.

Can I make mini galettes instead of one large one?

Yes, you can portion the dough and filling to make mini galettes. Adjust the baking time accordingly, as they may cook faster than a single large galette.
