A keto strawberry rhubarb crisp offers the perfect solution sweet, tart, and topped with a golden, buttery crumble. It’s a guilt-free way to enjoy dessert while sticking to your ketogenic diet. The combination of fresh strawberries and rhubarb brings both flavor and texture, while a low-carb topping made from almond flour and sugar alternatives keeps it keto-friendly. This dish is simple to prepare and works beautifully as a summertime treat, holiday dessert, or even a make-ahead option for special occasions.
Why Strawberry Rhubarb Crisp Works on a Keto Diet
Low-Carb Fruits and Ingredients
Strawberries and rhubarb are both naturally lower in carbs compared to other fruits. While rhubarb is technically a vegetable, it’s often used in desserts due to its tart, fruity flavor. Combining these two creates a satisfying base that doesn’t overload you with sugar. With the right sweetener and topping, you can enjoy this dessert without getting knocked out of ketosis.
Healthy Fats and Nutrients
The crisp topping often includes almond flour, butter, and chopped nuts all of which are rich in healthy fats and protein. These ingredients provide energy, satiety, and texture. Unlike traditional crisps that use oats and sugar, the keto version focuses on nutrient-dense, low-glycemic ingredients that support your dietary goals.
Essential Ingredients for Keto Strawberry Rhubarb Crisp
Fruit Filling
- 2 cups chopped rhubarb (fresh or frozen)
- 2 cups sliced strawberries (fresh is best)
- 1/3 cup erythritol or monk fruit sweetener (adjust to taste)
- 1 teaspoon vanilla extract
- 1/2 teaspoon ground cinnamon
- 1 tablespoon lemon juice (optional, for added brightness)
Low-Carb Crisp Topping
- 1 cup almond flour
- 1/2 cup chopped pecans or walnuts
- 1/3 cup unsweetened shredded coconut (optional for texture)
- 1/4 cup erythritol or other keto sweetener
- 1/4 teaspoon salt
- 1/2 teaspoon cinnamon
- 1/3 cup melted butter or coconut oil
Step-by-Step Preparation
Preparing the Filling
Start by preheating your oven to 350°F (175°C). In a medium mixing bowl, combine chopped rhubarb and sliced strawberries. Add your keto sweetener, cinnamon, vanilla extract, and lemon juice. Stir until the fruit is evenly coated and well mixed. Pour this mixture into a greased 9×9-inch baking dish and spread it evenly across the bottom.
Making the Topping
In a separate bowl, mix almond flour, chopped nuts, shredded coconut (if using), sweetener, cinnamon, and salt. Add the melted butter or coconut oil and stir until everything is coated and crumbly. The mixture should resemble a coarse, grainy texture that sticks together when pressed slightly.
Assembling and Baking
Sprinkle the topping evenly over the fruit layer. Try to cover as much of the surface as possible without packing it down. Place the baking dish in the preheated oven and bake for 30 to 35 minutes, or until the top is golden brown and the fruit is bubbling. Let it cool for 1015 minutes before serving so the filling can thicken slightly.
Serving Ideas
Perfect Companions
This keto strawberry rhubarb crisp is delicious on its own, but it can be even better with keto-friendly whipped cream or a scoop of low-carb vanilla ice cream. These additions provide a creamy contrast to the tart fruit and crunchy topping. Serve it warm for the best experience, or chill it for a cool, refreshing dessert during hot weather.
Portion Control and Net Carbs
Depending on the size of your servings, each portion typically has about 58 grams of net carbs. Always check your specific ingredients to calculate exact macros. Keeping your portion size in check will help you stay within your daily carb limits while still enjoying a sweet treat.
Tips for Success
Use Fresh Ingredients
Whenever possible, opt for fresh strawberries and rhubarb. Fresh fruit offers better flavor and texture. If using frozen rhubarb, make sure to thaw and drain it before baking to avoid excess moisture in the dish.
Sweetener Options
Choose a low-carb sweetener that suits your taste. Erythritol and monk fruit blends work well and don’t leave a bitter aftertaste. Adjust the sweetness depending on how tart your rhubarb is and your personal preference.
Customize the Topping
Feel free to get creative with the topping. Add a pinch of nutmeg, swap pecans for hazelnuts, or mix in sunflower seeds for extra crunch. Just make sure your additions are keto-compliant and low in carbs.
Storing and Reheating
How to Store Leftovers
Store leftover crisp in an airtight container in the refrigerator for up to 4 days. The topping may soften slightly, but the flavors will continue to develop. For longer storage, freeze individual portions and reheat when needed.
Reheating Tips
To bring back the crisp texture, reheat in an oven or toaster oven at 300°F (150°C) for about 10 minutes. Microwave reheating is convenient but may result in a softer topping. If reheating from frozen, allow it to thaw first for even warming.
