How to Make Vegan Leek Tart
-
Blend the Cream: Drain the soaked cashews and add them to a high-speed blender with water, nutritional yeast, and white vinegar. Blend for 30-45 seconds or until smooth, creating a creamy delight. Set aside.
-
Prepare the Leeks: Slice each leek in half lengthwise, rinse under cold water, pat dry, and slice crosswise into 1/2-inch thick pieces. This step ensures they’re ready to shine in the tart.
-
Sauté the Leeks: Melt the vegan butter in a large non-stick skillet over medium heat. Add the leeks and season with salt. Cook for 10-12 minutes, stirring regularly, until they soften.
-
Caramelize the Leeks: Continue to cook the leeks for another 2-3 minutes until they start to brown and caramelize—this brings out their sweet flavor! Remove from heat and set aside.
-
Mix the Filling: Pour the cashew cream into the skillet with the leeks. Add salt and pepper, stirring gently to combine. This rich mixture will enhance the tart’s flavor.
-
Preheat the Oven: Preheat your oven to 355 °F (180°C) so it’s ready when the tart is assembled.
-
Make the Crust: In a bowl, combine softened vegan butter, flour, salt, and water. Knead for about 2 minutes until a dough forms, adding more water if too dry.
-
Shape the Dough: Flatten the dough on a floured surface to about 1/4-inch thickness. Grease an 8-inch tart pan, transfer the dough into it, and cut off any excess. Prick the bottom with a fork to prevent bubbles during baking.
-
Fill the Tart: Spread the prepared leek and cashew filling evenly into the pie crust. Every bite will be packed with flavor!

Tips for the Best Vegan Leek Tart
-
Soak Cashews Properly: Ensure your cashews are soaked overnight. This step is crucial for achieving a smooth, creamy consistency in your cashew cream.
-
Perfectly Cooked Leeks: Don’t rush the sautéing process! Allow the leeks enough time to caramelize for the best flavor, avoiding a raw or overly crispy texture.
-
Avoid Dough Dryness: If your tart dough feels dry, add water a tablespoon at a time until it forms a smooth ball. This prevent a crumbly crust.
-
Watch the Baking Time: Every oven is different! Keep an eye on your tart during the last few minutes of baking to prevent it from getting too dark.
-
Let it Cool: Allow the Vegan Leek Tart to cool for a few minutes before slicing. This helps the filling set and makes for cleaner, neater slices.

Vegan Leek Tart Recipe FAQs
How do I select the best leeks for this tart?
When choosing leeks, look for ones that are firm and vibrant with a rich green color. The white part should be free from dark spots or blemishes, and the stalk should feel crisp. Avoid leeks that appear wilted or have yellowing leaves, as they may not provide the best flavor.
How do I store leftover Vegan Leek Tart?
To store your Vegan Leek Tart, keep it in an airtight container in the refrigerator for up to 3 days. When ready to enjoy it again, reheat individual slices in the microwave for quick warmth or in the oven at 350°F (175°C) until heated through. This way, you can savor leftovers without losing that delicious texture!
Can I freeze Vegan Leek Tart?
Absolutely! You can freeze your Vegan Leek Tart unbaked for up to 1 month. Wrap it tightly in plastic wrap and then in foil to protect it from freezer burn. When you’re ready to bake it, simply remove it from the freezer, unwrap, and bake directly from frozen, adding an extra 5-10 minutes to the baking time until golden brown.
What are some common issues when making the crust?
If your tart crust is crumbly, it may need more moisture. Add water, a tablespoon at a time, until it forms a smooth ball. If it’s too sticky, sprinkle on a little flour as you roll it out. Make sure to prick the bottom with a fork to prevent bubbles during baking. Patience is key here!
Are there any dietary considerations with this Vegan Leek Tart?
Yes! This recipe is entirely vegan, so it contains no dairy or animal products. If you’re cooking for someone with nut allergies, you could substitute the cashew cream with a soy-based or seed-based cream alternative. Always check the labels of pre-packaged ingredients to ensure they meet dietary restrictions.
