In this tart, it shines, providing a bright counterpoint to the rich, almond-flour based crust.

Beyond its delicious taste, this tart is incredibly versatile. It's perfect for a spring gathering, a special occasion, or simply as a comforting treat any day of the week.

Tips for the Perfect Crust and Filling

A few crucial tips will help you achieve baking perfection. For the crust, ensure you press the mixture firmly into the tart pan – this creates a sturdy base that won't crumble. Pre-baking the crust is also essential to prevent a soggy bottom. As for the filling, cooking the rhubarb until softened and then thickening it with glucomannan ensures a lovely, spreadable consistency that sets beautifully.

After baking, patience is key! Allow the tart to cool completely in the pan before attempting to remove it or slice.

Keto Rhubarb Crumble Tart


  • Total Time: 1 hour 30 minutes (includes cooling)
  • Yield: 10 servings 1x
  • Diet: Keto, Low-Carb, Gluten-Free, Sugar-Free

Description

A delightful low-carb and sugar-free tart featuring tangy rhubarb filling nestled in a buttery almond flour crust with a crunchy crumble topping.


Ingredients

Scale

2 cups almond flour
1/3 cup Swerve Brown
1/3 cup Swerve Granular
2 tbsp coconut flour
1/2 tsp cinnamon
1/4 tsp salt
1/2 cup butter, melted
1/4 cup chopped pecans or walnuts (optional)
3 cups chopped rhubarb
2 tbsp water
1/3 cup allulose (or BochaSweet)
1/4 tsp glucomannan (or xanthan gum)


Instructions

Step 1: Preheat the oven to 325°F (160°C) and grease a 9-inch metal tart pan with a removable bottom. In a large bowl, whisk together the almond flour, Swerve Brown, Swerve Granular, coconut flour, cinnamon, and salt, breaking up any clumps. Stir in the melted butter until well combined.
Step 2: Press about 2/3 of the dough firmly into the bottom of the prepared pan. There's no need to go up the sides. Bake for 15–20 minutes, until just golden brown around the edges. Remove and let cool for 15 minutes to firm up.
Step 3: While the crust cools, prepare the rhubarb filling. In a medium saucepan, combine the chopped rhubarb, water, and allulose (or BochaSweet). Bring to a simmer and cook for about 5 minutes, until the rhubarb has softened and released some of its juices. Stir in the glucomannan (or xanthan gum), which will help thicken the filling. Let it cool to room temperature.
Step 4: Once the rhubarb filling has cooled, spread it evenly over the cooled crust. Add the chopped pecans or walnuts (if using) to the remaining crust mixture, then sprinkle this crumble topping evenly over the rhubarb filling. Gently press the crumble topping to adhere.
Step 5: Bake for another 20 minutes, or until the crumble topping is golden brown. Remove from the oven and let cool completely in the pan before attempting to remove the sides (this is crucial for the tart to set properly).
Step 6: Once fully cooled, gently loosen the tart from the pan using a small sharp knife if needed. Remove the sides and carefully transfer the tart to a serving plate. Slice into 10 equal portions and serve. Enjoy your delicious keto rhubarb crumble tart!

Notes

For an even richer flavor, you can toast the pecans or walnuts lightly before adding them to the crumble topping. If rhubarb is too tart, you can increase the allulose slightly in the filling.
