How to Make Vegan Leek Tart
-
Prepare the Cashew Cream: Drain the soaked cashews and add them to a high-speed blender. Pour in the water, then add nutritional yeast and white vinegar. Blend for 30-45 seconds until smooth and creamy. Set aside for later.
-
Slice the Leeks: Take each leek and slice it in half lengthwise. Rinse well under cold water to remove any dirt, then pat dry. Cut into 1/2-inch thick slices for even cooking.
-
Sauté the Leeks: Melt 2 tablespoons of vegan butter in a large non-stick skillet over medium heat. Add the sliced leeks, seasoning with a pinch of salt. Cook for about 10-12 minutes, stirring regularly until softened.
-
Caramelize the Leeks: Continue cooking the leeks for an additional 2-3 minutes until they start to brown and caramelize, adding a rich flavor. Remove the skillet from heat once done.
-
Combine with Cashew Cream: Pour the prepared cashew cream into the skillet with the leeks. Gently toss to coat, adding salt and pepper. Stir to combine, adjusting seasonings to taste. Set this savory filling aside.
-
Preheat the Oven: Set your oven to preheat at 355°F (180°C) so it’s ready for the tart.
-
Make the Dough: In a bowl, mix the softened vegan butter, flour, salt, and water. Knead for about 2 minutes until a firm dough forms. Add more water if necessary until the dough holds together. Shape into a ball and flatten into a thick disc.
-
Roll Out the Dough: On a floured surface, roll out the dough to a ¼-inch thickness. Lightly grease an 8-inch tart pan with vegan butter, carefully transferring the dough into the pan. Trim any excess and prick the bottom with a fork.
-
Add the Filling: Spread the leek mixture into an even layer on top of the crust, ensuring it’s evenly distributed for each delicious bite.
-
Bake the Tart: Place the tart in the preheated oven and bake for 30-35 minutes or until the crust turns golden brown. Allow it to cool for a few minutes before slicing and serving.
Optional: Garnish with fresh herbs for an added burst of flavor.

Expert Tips for Vegan Leek Tart
-
Soak Cashews Properly: Make sure to soak your cashews overnight; this is key for achieving that luscious creaminess in your filling.
-
Leek Preparation: Always rinse leeks thoroughly under cold water; dirt can hide between their layers. A clean leek leads to a flavorful tart.
-
Don’t Rush Caramelization: Give the leeks enough time to brown. This step enhances their sweetness, making your Vegan Leek Tart truly unforgettable.
-
Check Dough Consistency: Be mindful of your dough; if it feels too dry, add a little more water. A well-formed dough ensures a flaky crust!
-
Taste as You Go: Before baking, taste the leek filling to adjust seasonings. A little extra salt or pepper can elevate the flavors wonderfully.
-
Cool Before Serving: Let the tart cool for a few minutes post-baking. This helps the filling set, making it easier to slice and serve.

Vegan Leek Tart Recipe FAQs
What should I look for when selecting leeks?
Absolutely! When choosing leeks, look for ones that are firm, with vibrant green tops and white stems without any dark spots or wilting. The leek should feel heavy for its size, indicating freshness. The greens are also edible and can add flavor to stocks or soups, so don’t discard them!
How long can I store the Vegan Leek Tart?
You can store the Vegan Leek Tart in an airtight container in the fridge for up to 3 days. Reheat slices in the oven at 350°F (175°C) for about 10-15 minutes for the best results. This way, the flavors remain vibrant, and the crust stays flaky!
Can I freeze leftovers of the Vegan Leek Tart?
Very easily! To freeze the tart, wrap it tightly in plastic wrap followed by foil to prevent freezer burn. It will stay fresh for up to 3 months. When you’re ready to enjoy it again, simply thaw it overnight in the fridge before reheating.
What can I do if my leek filling is too watery?
Great question! If your leek filling turns out watery, cook it for a few more minutes on medium heat after you combine it with the cashew cream. This will help evaporate excess moisture. You can also add a tablespoon of cornstarch mixed with a little water to thicken the mixture if needed.
Is this Vegan Leek Tart suitable for gluten-free diets?
Absolutely! You can swap the flour in the crust for a gluten-free all-purpose blend. Make sure to check that your vegan butter is also gluten-free. The tart will still be delicious, but the texture may vary slightly. Always read labels to ensure safety if you have severe allergies.
Can I use other vegetables instead of leeks in the tart?
Very much so! Feel free to use a combination of seasonal vegetables like spinach, zucchini, or mushrooms. Just sauté them similarly as you would the leeks, and adjust the cooking times based on the vegetable’s water content and cooking requirements. The more the merrier when it comes to flavor!
