Growing up on a farm meant lots of fresh fruit and vegetables. My mother had a healthy rhubarb patch and I remember picking it and even eating it raw. Yep, that’s a little tart but also tasty. Rhubarb is a naturally low-carb vegetable. That’s right, rhubarb is. a vegetable. This Low Carb Rhubarb tart is the perfect combination of sweetness and tartness all in one dessert.

Fresh rhubarb can be easily cooked into a sauce (stewed Rhubarb) and used as toppings for ice cream or in recipes like our Sugar-Free Strawberry Rhubarb Cheesecake (which is really yummy, by the way). When making this recipe, you will find many of the ingredients in your diabetic-friendly pantry.


In this post, I will provide a list of kitchen tools needed to make this recipe, a shopping list of ingredients, the recipe for our Low Carb Rhubarb Tart, and the nutritional information per serving. I will also provide tips for buying rhubarb, just in case you are a first-timer.

Making the Crust

When making any of our diabetic-friendly recipes that use almond flour or coconut flour in the crust, it is a good idea to sift the dry ingredients. I did not include that in the instructions in the recipe but thought it deserved mentioning.

Sifting breaks up any lumps and keeps the flour light and fluffy.

Almond Flour is made by finely grinding almonds and Coconut Flour is made from finely ground dried coconut meat. When purchasing Almond or Coconut flour, always look for the extra-fine grind, for the best results when baking.

You can substitute the Almond Flour and Coconut flour with all-purpose flour, but keep in mind that the nutritional values will be altered and carbs will be increased.

The crust for this recipe should be fully baked prior to adding the filling.

Once baked, add filling and then spread rhubarb [pieces over the top. Once completed, bake in over as directed. (see image below)

Tips for buying fresh rhubarb

When shopping for Rhubarb, it is helpful to know that there are two types of rhubarb, field or farm-grown rhubarb and rhubarb that are grown in a greenhouse preferred to as hothouse rhubarb.

Field or farm-grown rhubarb is easily distinguished by its dark red stalks. The flavour of field or farm-grown rhubarb is much stronger and has a more intense rhubarb flavour.

The stalks should be firm. Firm rhubarb stalks mean that the stalks are not dried out. If you see limp or droopy stalks, do not purchase them. a firm stalk will be juicier and more flavourful than a limp one.

Shiny skin on the rhubarb also is a good indicator of the freshness of the rhubarb. if the stalks appear dull they are past their peak. The nice shine or gloss on the stalk is a sign of freshness.

Field or farm-grown rhubarb is usually found in local farmers’ markets and local markets that sell fresh farm produce.

Opinions vary, but I always find that the young thinner stalks are sweeter and juicier than the big fat ones.

Hothouse Rhubarb is usually found in supermarkets or large grocery store chains.

Hothouse rhubarb is lighter in colour, usually with pinkish or green stalks.

Whichever you choose, avoid rhubarb that has blemished stalks or ends that are curling or appear to be drying out.
