Low Fat Blueberry Pie Recipe: Bursting Berry Goodness Without Compromise

I’ve crafted a pie that delivers all the blueberry goodness you love with a lighter touch. This version proves you can enjoy dessert without the guilt.

The secret lies in smart substitutions—a low-fat crust and reduced-sugar filling that still burst with juicy berry flavor. Every bite is as satisfying as the original.

Ingredients for Low Fat Blueberry Pie

Lightened crust, sweet-tart filling, and all the blueberry joy you expect.

The crust is where the magic starts. Light butter keeps it flaky without the fat—Land O’Lakes or Smart Balance work well. For the blueberries, fresh wild Maine berries are ideal if you can find them (check Whole Foods or Trader Joe’s in summer), but any fresh berries will do. Just avoid frozen unless thawed and drained completely (they release too much liquid otherwise).

No erythritol? Monk fruit sweetener or Stevia blends work at a 1:1 ratio. Cornstarch can be swapped for arrowroot powder if you prefer—same amount. If you’re out of vanilla, a splash of almond extract adds a nice depth (use half the amount). The lemon zest is non-negotiable though—it brightens all that sweetness.

The pie keeps 3-4 days at room temperature (covered loosely with foil). For longer storage, it freezes beautifully for up to 3 months. Slice before freezing so you can grab just what you need. Thaw at room temp for about an hour before serving.

Step-by-Step Instructions for Low Fat Blueberry Pie

This method delivers all the fruity richness with a lighter touch that still satisfies.

Step 1: Prepare the Lightened Pie Crust

In a food processor, pulse the 2 cups All-Purpose Flour with 0.25 tsp Salt and the 0.25 cup Granulated Sugar. Add the 0.5 cup Light Butter (cold and cubed) and pulse until the mixture resembles coarse crumbs with pea-sized butter pieces visible.

With the processor running, add the 6 tbsp Ice Water one tablespoon at a time through the feed tube. Stop as soon as the dough just begins to come together—overworking develops gluten, making the crust tough. The dough should hold when pressed but still look slightly shaggy.

Step 2: Chill and Roll the Dough

Divide the dough into two equal portions, flatten into discs, and wrap in plastic. Refrigerate for at least 1 hour (or up to 2 days). This resting period relaxes the gluten and allows the Light Butter to firm up, making it easier to roll.

On a lightly floured surface, roll one disc into a 12-inch circle and transfer to a 9-inch pie dish. Trim the edges to leave a ½-inch overhang. Reserve the second disc for the top crust. Chill both while you prepare the filling to prevent shrinking during baking.

Step 3: Make the Low-Sugar Blueberry Filling

In a large bowl, gently toss the 5 cups Fresh Blueberries with the 0.75 cup Granulated Erythritol, 0.25 cup Cornstarch, 2 tbsp Lemon Juice, 1 tbsp Lemon Zest, 1 tsp Vanilla Extract, and 0.5 tsp Ground Cinnamon. Let this mixture sit for 10-15 minutes.

The Cornstarch will absorb some of the blueberry juices, creating a slightly thickened mixture. This resting time ensures the filling sets properly during baking rather than turning into a runny mess. Stir once more before adding to the crust.

Step 4: Assemble and Bake the Pie

Pour the blueberry filling into the chilled bottom crust. Roll out the second dough disc and place it over the filling. Trim, seal, and crimp the edges, then cut 4-5 slits in the top crust to allow steam to escape.

For a golden finish, brush the top crust with the 1 whole Large Egg White (lightly beaten). Bake at 375°F for 45-50 minutes until the crust is golden brown and the filling bubbles visibly through the vents. If the edges brown too quickly, cover them with foil.

Step 5: Cool Completely Before Serving

Let the pie cool on a wire rack for at least 2 hours. This cooling time is crucial—the filling continues to set as it cools, and slicing too soon will give you a soupy pie rather than clean slices.

The crust should remain flaky and the filling thick enough to hold its shape. Serve at room temperature for the best texture, where the Fresh Blueberries burst with every bite and the Light Butter crust provides the perfect crisp contrast.
