I found this recipe from my grandmother’s collection that my Aunty Irma put together for the family.  It was titled ‘Spring Rhubarb Dessert’.  The subtitle was ‘Art’s favorite dessert’.  Art, being my Uncle Art.

When I gave my sister a piece, she loved it and said No wonder it was his favorite!  Even my super picky 21 year old son loved it.  You are going to love it too!

At first I was a little intimidated by it, but it was surprisingly easy to turn this Spring Rhubarb Dessert into my Keto Rhubarb Lemon Meringue Squares.

Can I Eat Rhubarb on Keto?

Many people are not aware that rhubarb is actually a vegetable and not a fruit!  This is because rhubarb is often featured in recipes that are associated with fruit such as crumble and pie recipes.

If you are wondering how many net carbs in rhubarb, you will be pleasantly surprised to find out that 1 cup of diced rhubarb has only 26 calories and 3.3 net carbs.  You can find out other Rhubarb Nutrition Facts in this article

So the answer is a resounding YES!  Feel free to eat rhubarb on Keto!

Tips and Tricks for Making Keto Rhubarb Lemon Meringue Squares

  • The original recipe calls for the juice and zest of 1 orange.  I didn’t have an orange so I used 2 lemons. If I ever have an orange in the house, I might try it and if I do I’ll report back here with an update.
  • You can meal prep by making the rhubarb custard filling a day ahead and refrigerate until you are ready to bake.
  • I couldn’t find my cream of tartar so I made it without and it turned out perfectly fine
  • When the baking is finished, allow to cool and then refrigerate until cold.  The lemon flavor seeps down into the bottom layer and the result is a super moist, lemony piece of heaven.
  • For those using different sweeteners:  The original recipe calls for the following amounts of sugar (which I lowered for this recipe), 1/4 cup in the bottom layer, 1 1/4 cup in the custard layer, and 1/3 cup in the meringue.

    Now I remember why I don’t follow your blog and recipes. Could you please include the actual sugar equivalent in the recipe? Not all artificial sweeteners sweeten the same. It is very frustrating and disappointing to want to try one of your recipes and run up against the wall because I don’t have the information to adjust the sugar to the sweetener I use. Feeling sad, no rhubarb bars for us today,

      Sorry Traci, I did not realize this was an issue for anyone! Nobody has ever mentioned it before. The reason I don’t include in the nutrition count is because the calculator includes the carbs but doesn’t deduct the sugar alcohols which really skews the carb count. But I will go and edit the recipe to include the orginal amount of sugar used (which I lowered for myself because I thought it was way too sweet!). The original recipe calls for: 1/4 c sugar in the base, 1 1/4 c sugar in the filling, 1/3 c sugar in the meringue topping. I hope that helps.

        Weird that comment posted twice. Thanks for that information. I too find most sweetened foods to be overly sweet and the same goes for most substitute sweeteners. That is one reason I like erythritol, it is sightly (25 or 30%) less sweet than table sugar so I can simply use the measurements or cut them just a little..Bars tonight after all. Yippee.

          Lol, I am happy that you will try them now!
