What to expect

Louise holding a vegan lemon bars

Vegan lemon bars combine a tender, slightly crumbly shortcrust base with a silky, tangy lemon curd topping. The crust offers a subtle lemon aroma from added zest and stays pleasantly crumbly when handled gently. The lemon curd is thickened with cornstarch and colored naturally with a pinch of turmeric, producing a bright yellow filling without affecting flavor.

The method is intentionally streamlined: mix wet and dry crust ingredients, press into a pan, bake briefly, prepare the curd on the stovetop, pour it over the pre-baked crust, and finish with a short bake. The end result is a dessert that looks impressive, tastes fresh and lemony, and is simple enough for home cooks of all levels.

Ingredients and substitutions

Vegan shortcrust pastry

ingredients for the pie crust
  • Flour: Use all-purpose flour or a 50/50 blend of all-purpose and whole wheat for a slightly nuttier flavor and firmer texture.
  • Sugar: White granulated sugar works well; brown sugar gives a hint of caramel depth if preferred.
  • Oil: Any neutral vegetable oil is fine—sunflower, canola, or light olive oil are common choices.
  • Lemon zest: Grated zest adds a bright citrus note to the crust; use organic lemons if you plan to use the peel in the curd as well.
  • Baking powder: A small amount helps the crust stay tender rather than dense.

Vegan lemon curd

  • Plant milk: Any plant milk will work: oat, soy, almond, rice, or others. Thicker milks give a richer curd.
  • Sugar: Granulated sugar, cane sugar, or other granulated alternatives.
  • Cornstarch: Essential for thickening the curd into a custard-like consistency.
  • Lemons: You need both lemon juice and lemon peel (not the same as grated zest used in the crust). Strain the juice to remove pulp and seeds.
  • Turmeric: A pinch for color only; it won’t affect the taste when used sparingly.

Instructions

Vegan shortcrust pastry

Preheat the oven to 350°F (180°C). Line a 10 x 10 inch (25 x 25 cm) baking pan with parchment paper, leaving an overhang on two opposite sides to make lifting the baked slab easier.

In a medium bowl combine 1/4 cup (50 g) sugar, 3 tablespoons (45 g) water, 3 tablespoons (40 g) vegetable oil, and the grated zest of one lemon. Mix until the sugar has started to dissolve and the mixture is evenly combined.

Sift in 1⅓ cups (200 g) all-purpose flour and 1 teaspoon (5 g) baking powder. Stir with a spatula until the flour absorbs the liquid, then briefly knead the dough by hand for about one minute in the bowl. The goal is to bring the dough together without overworking it; minimal kneading keeps the crust tender and crumbly rather than tough.

Transfer the dough to the prepared pan and press it evenly across the bottom to form a compact base. Use your fingers to press and smooth the surface so it holds together well.

Prick the crust a few times with a fork to prevent large air bubbles, then bake for 15 minutes at 350°F (180°C). Remove from the oven and allow it to cool for about 10 minutes while you prepare the lemon curd; keep the oven on for the final bake.

Vegan lemon curd

While the crust cools, make the lemon curd. Start by removing the peel (large strips) from one lemon and add it to a medium saucepan. Use the grated zest you reserved for the crust; the peel here adds aromatic oils during cooking.

Juice three medium lemons (including the zested and peeled lemons if applicable) to yield about 1/3 cup (80 g) lemon juice. Strain the juice through a fine sieve to remove any pulp and seeds and set aside.

To the saucepan with the lemon peel add 2 cups (500 g) plant milk, 1/2 cup (100 g) sugar, and 1/2 cup (60 g) cornstarch. Add a pinch of turmeric for color if desired. Whisk thoroughly to eliminate lumps before heating.

Place the saucepan over medium heat and whisk continuously as the mixture warms. Continue stirring until the mixture thickens to a custard-like consistency. Once thickened, remove and discard the lemon peel, then stir in the strained lemon juice. Keep stirring for another minute so the lemon juice is fully incorporated and the curd is smooth and glossy.

The curd should be pourable but thick enough to hold when chilled. Taste and adjust sweetness if needed before pouring over the crust.

Pour the warm lemon curd onto the pre-baked crust and spread it evenly with a spatula. Return the pan to the oven and bake at 350°F (180°C) for another 15 minutes to set the filling.

Remove from the oven and allow the bars to cool on a rack until they reach room temperature, then chill in the refrigerator for about an hour to fully set. Use the parchment overhang to lift the slab from the pan, place it on a cutting board, and slice into 16 squares or desired portions.

Just before serving, dust lightly with powdered sugar if desired. Keep in mind that powdered sugar will begin to dissolve on moist surfaces after a few seconds, so add it right before presentation.

Variations

You can adapt this recipe in a few simple ways: bake the crust longer for a crunchier base and create a tart-like dessert, or reduce baking time on the crust and finish with a lattice or rustic top to make a crostata-style dessert. Swap some of the all-purpose flour for whole wheat for added texture, or replace a portion of sugar with a lower-glycemic sweetener to suit dietary preferences. Fresh berries, a thin layer of raspberry jam under the curd, or a sprinkle of toasted coconut provide pleasant flavor contrasts.

For a complete meal plan, serve these vegan lemon bars as a refreshing dessert after a casual starter such as mini pizzas, followed by a hearty main like oven-baked chickpea stew and a bright side of cauliflower rice with lemon and parsley. The lemon bars offer a light, citrusy finish that complements savory mains without being overly heavy.

Dinner menu ideas

Serve these vegan lemon bars as a dessert with simple, balanced dishes that highlight Mediterranean and plant-based flavors. They pair especially well with light mains and lemon-accented sides to create a cohesive menu.

Storage

At room temperature, the bars will keep well for up to half a day. For longer storage, refrigerate them flat on a plate or tray for up to 2–3 days. Avoid stacking bars directly on top of each other so the filling and crust remain intact and do not become soggy. For longer preservation, wrap individual bars in plastic wrap and store in an airtight container in the refrigerator.
