When blueberries are in season, it doesn’t take much to turn them into something special. This easy Fresh Blueberry Pie lets the fruit shine with a simple homemade filling tucked into a prepared graham cracker crust.
Inspired by a recipe from Hit the Spot by WeightWatchers, it uses just five simple ingredients and comes together with very little hands-on time. Part of the blueberries are gently cooked to create a glossy filling, while the rest are stirred in at the end so they stay whole and juicy.
It’s the kind of old-fashioned summer dessert that’s perfect for cookouts, family dinners, and holiday celebrations. Serve each slice chilled on its own or with a dollop of light whipped topping or a small scoop of vanilla frozen yogurt.

- Just 5 simple ingredients
- Fresh blueberry flavor in every bite
- Easy to make with a prepared graham cracker crust
- Perfect make-ahead dessert
- Light enough for summer entertaining
Ingredients & Notes
- Cornstarch – Thickens the blueberry filling without masking the fruit.
- Water – Combines with the cornstarch to create the filling.
- Fresh blueberries – You’ll cook half and stir the remaining berries in at the end for the best texture.
- Granulated sugar – Sweetens the filling while letting the blueberries remain the star.
- Reduced-fat graham cracker crust – A convenient shortcut that pairs beautifully with the blueberries.

How to Make Summertime Fresh Blueberry Pie
Step 1: Gather and prepare all ingredients.
Step 2: In a large saucepan, whisk together the cornstarch and water until smooth. Add 3 cups of the blueberries (about half) and the sugar to the pan. Bring to a boil over medium-high heat, stirring frequently and pressing the blueberries against the sides and bottom of the saucepan with a wooden spoon (affiliate link), crushing them. Continue cooking while constantly stirring until the mixture thickens and boils, about 1 minute.
Step 3: Turn off the heat and stir in the remaining blueberries.
Step 4: Pour the filling into the prepared graham cracker crust and chill in the refrigerator until set, about 5 hours or overnight.
Step 5: Cut into 8 wedges and serve.

Recipe Tips
- Stir constantly while the filling thickens.
- Fold in the remaining blueberries after removing the pan from the heat so they stay whole.
- Chill for at least 5 hours, or overnight, before slicing.
- A sharp knife wiped clean between cuts makes the neatest slices.
Variations
- Add a teaspoon of fresh lemon zest to brighten the flavor.
- Stir in a little cinnamon or almond extract.
- Substitute a traditional baked pie crust if you prefer.
- Top with light whipped topping, vanilla frozen yogurt, or Greek yogurt.
Storage
Cover and refrigerate for up to 4 days. This pie is best served well chilled.
