Roasted Vegetable Galette (Vegan) Recipe

I love how this Roasted Vegetable Galette turns simple winter produce into a golden, flaky centerpiece that looks far fancier than it is. One slice and it’s easy to see why it disappears fast.

During cold winter days I find myself spending much more time in my kitchen, mostly because I start craving food with real heft and a little drama. I love this Roasted Vegetable Galette because it looks rustic in the best way, messy edges and all, but still feels special enough to stop me mid-bite.

The flaky crust, the deeply roasted vegetables, that sharp little hit of Dijon mustard. So good.

I’m obsessed with how the zucchini goes tender and slightly sweet against the savory filling. And honestly, I adore anything that lands on the table looking this gorgeous without trying too hard.

Ingredients

• All-purpose flour makes the crust sturdy, tender, and easy to love.
• Cold vegan butter gives those flaky bits you’ll absolutely notice.
• A tiny bit of sugar helps the crust brown nicely.
• Salt keeps the dough from tasting flat or boring.
• Olive oil helps the veggies roast up glossy and rich.
• Balsamic vinegar adds sweet tang, especially with tomatoes and onions.
• Garlic brings that cozy, “something smells amazing” kitchen moment.
• Thyme and rosemary make it taste herby, earthy, and homemade.
• Zucchini and eggplant turn soft, savory, and almost creamy.
• Red pepper and onion add sweetness without trying too hard.
• Cherry tomatoes get juicy, bright, and a little jammy.
• Plus, Dijon mustard adds a sharp little kick under everything.
• Nutritional yeast or vegan Parmesan brings salty, cheesy vibes.
• Basically, cornmeal keeps the bottom from getting sad and soggy.

Ingredient Quantities

• All purpose flour 1 1/4 cups (160 g)
• Cold vegan butter 1/2 cup (113 g) cubed or cold coconut oil solid
• Granulated sugar 1 teaspoon
• Fine salt for crust 1/2 teaspoon
• Ice water 3 to 4 tablespoons
• Olive oil 3 tablespoons
• Balsamic vinegar 1 tablespoon
• Garlic 2 cloves minced
• Fresh thyme leaves 1 teaspoon, or 1 tablespoon chopped
• Fresh rosemary 1 teaspoon chopped
• Fine salt for vegetables 1 teaspoon
• Freshly ground black pepper 1/2 teaspoon
• Zucchini 1 medium, thinly sliced
• Eggplant 1 small, thinly sliced
• Red bell pepper 1, seeded and sliced
• Yellow onion 1 small, thinly sliced
• Cherry tomatoes 1 cup, halved
• Mushrooms 1 cup, sliced (optional)
• Dijon mustard 1 tablespoon
• Non dairy milk 1 tablespoon for brushing
• Vegan grated Parmesan or nutritional yeast 2 tablespoons (optional)
• Coarse cornmeal or extra flour for dusting 1 to 2 teaspoons

How to Make this

1. Make the crust by whisking 1 1/4 cups (160 g) all purpose flour with 1 teaspoon granulated sugar and 1/2 teaspoon fine salt, then cut in 1/2 cup (113 g) cold vegan butter or solid coconut oil until pea sized pieces remain; sprinkle 3 to 4 tablespoons ice water a tablespoon at a time and gently bring the dough together, form a disk, wrap and chill at least 30 minutes.

2. Preheat oven to 425F and line a baking sheet with parchment; toss sliced zucchini, eggplant, red bell pepper, yellow onion, cherry tomatoes, and mushrooms if using with 3 tablespoons olive oil, 1 tablespoon balsamic vinegar, 2 minced garlic cloves, 1 teaspoon fresh thyme leaves (or 1 tablespoon chopped), 1 teaspoon chopped fresh rosemary, 1 teaspoon fine salt and 1/2 teaspoon freshly ground black pepper.

3. Spread the vegetables on the prepared sheet in a single layer and roast 15 to 20 minutes until tender and lightly browned, stirring once; remove and let cool slightly.

4. On a lightly floured surface or dusted with 1 to 2 teaspoons coarse cornmeal, roll chilled dough into a rough 12 inch circle about 1/8 inch thick and transfer to the parchment lined sheet.

5. Spread 1 tablespoon Dijon mustard over the center of the dough leaving a 2 inch border.

6. Arrange the roasted vegetables over the mustard in an even layer, draining any excess liquid from the tomatoes as you place them; sprinkle 2 tablespoons vegan grated Parmesan or nutritional yeast if using.

7. Fold the 2 inch border up over the filling, pleating as needed to form a rustic edge and leaving the center exposed; brush the crust with 1 tablespoon non dairy milk.

8. Chill the assembled galette in the refrigerator 10 minutes while you lower the oven to 400F for baking.

9. Bake the galette at 400F for 30 to 35 minutes until the crust is golden and vegetables are bubbling; rotate the pan halfway through for even browning.

10. Let rest 10 minutes, then slice and serve warm or at room temperature, garnishing with extra thyme or rosemary if desired.

Roasted Vegetable Galette (Vegan) Recipe Substitutions and Variations

• All purpose flour (1 1/4 cups / 160 g)
  • Whole wheat pastry flour: use 1:1 for a nuttier flavor and slightly denser crust; chill dough well.
  • Gluten free flour blend: use a 1:1 baking blend that contains xanthan or guar for structure.
  • Spelt flour: use 100% spelt for a tender, slightly sweet crust; handle gently and avoid overworking.
• Cold vegan butter or solid coconut oil (1/2 cup / 113 g)
  • Cold vegetable shortening: yields a flaky crust but with milder flavor; use same amount.
  • Cold extra-virgin olive oil in a blended method: use 3 parts flour to 1 part oil by volume and mix until crumbly for a tender, flavorful crust.
  • Equal parts vegan butter and coconut oil: combines flavor and flakiness while remaining solid when cold.
• Balsamic vinegar (1 tablespoon)
  • Red wine vinegar plus 1/2 teaspoon maple syrup: mimics sweetness and tang of balsamic.
  • Sherry vinegar: slightly nuttier and less sweet, use 1 tablespoon.
  • Apple cider vinegar plus pinch of brown sugar: bright and slightly sweet alternative.
• Dijon mustard (1 tablespoon)
  • Whole grain mustard: similar tang with visible seeds and texture.
  • Yellow mustard plus a pinch of ground mustard powder: milder but acceptable in a pinch.
  • Vegan mayonnaise with a squeeze of lemon: for creaminess and brightness, use about 1 tablespoon.

Pro Tips

1. Chill the dough well and handle it lightly. Cold fat and minimal handling keep the crust flaky, so press and roll just enough to bring it together and pop it back in the fridge before rolling if it warms up.

2. Roast the vegetables until they have some color. A little caramelization adds depth, and pulling them when they are lightly browned prevents sogginess once they go on the crust.

3. Pat or drain the tomatoes and any very juicy pieces before assembling. Excess moisture is the main culprit for a soggy center, so remove seeds or blot with paper towel if needed.

4. Make the non dairy milk brush richer for color and shine by whisking in a tiny splash of olive oil and a pinch of salt. It gives the crust a nicer golden finish without changing the flavor.

5. Cut all vegetables to similar thickness and arrange with intention. Even slices cook at the same rate, and a tidy, layered presentation makes each slice more appealing when served warm or at room temperature.
