Ingredients and substitutions
Here are a few quick notes about the ingredients in this recipe. You can see a complete list of ingredients and instructions in the recipe card below.
Almond and oat flours - A combination of almond flour and gluten-free oat flour create our press-in tart crust recipe. I like using Bob's Red Mill brand for both.
Organic cane sugar - A little bit is used for the sweet tart crust and the lemon filling.
Lemons - We are using whole fresh lemons here. Both lemon zest and fresh lemon juice for lots of tangy lemon flavor. You can use regular lemons, or for a sweeter, less tart filling, you can use Meyer lemons.
Maple syrup - A perfect and unrefined sweetener for the tangy-sweet lemon layer. Honey can be substituted (if not vegan) or agave nectar.
Coconut oil - Combined with coconut cream, this helps us achieve a "lemon curd filling."
Coconut cream - This rich ingredient can be store-bought or by chilling a can of full-fat coconut milk overnight.
Arrowroot starch - Also known as arrowroot starch, this helps thicken the filling. Corn starch can be substituted.
Raw cashews - Once soaked and combined with the other ingredients, cashews create a creamy tart filling. (Just like in these gluten-free lemon bars!)
Vanilla extract - I recommend a pure vanilla extract when possible for the best flavor.
Tessa's Tip: A touch of ground turmeric gives our vegan lemon curd a more vivid yellow color.

Tart Crust

- Transfer the crust dough to the prepared tart pan. Bake for 15 minutes and then allow to cool.
Lemon Filling
- Drain cashews and place back into blender. Add remaining filling ingredients to blender. Blend until smooth. Pour filling into parbaked crust. Smooth with spatula. Bake for 16-20 minutes. The edges of the crust should start to turn golden and the middle should be set.

I love the lemon/thyme combo. It looks and sounds incredible!
Tessa
Thanks so much, Kristen!!
Alissa
Love me some lemon curd. I really like the savory addition of thyme too!

I have a strange obsession with lemon curd despite never having tasted it. I just really like the idea of it and I imagine it tastes amazing.
these tartlets are so lovely! I like the simple combination of flavors you employed here: subtly sweet almond flour in the crust, beautiful rich lemon, and sharply fragrant thyme. you're making me wish I had tart pans (or muffin tins). do you think this would bake up decently in a standard pie dish?
Tessa
Hahaha, that is awesome and understandable. Lemon curd is pretty great!
Thank you! I do think the crust would bake up okay in a standard pie dish. If you press the dough about halfway up the sides, it should work and fill like a big tart!
