This creamy and refreshing no bake lemon blueberry pie doesn't require any cooking or baking. It's perfect for summer when you want something cool and delicious without heating up the kitchen. The vibrant purple filling transforms into a delightful frozen treat with minimal effort.
I first made this pie during a heatwave last summer when the thought of turning on the oven seemed unbearable. My family was so impressed by how something so simple could taste so incredible that it's now our go to summer dessert.
Ingredients
- Lemon juice: fresh squeezed provides the best tangy flavor that balances the sweetness perfectly
- Fresh blueberries: choose plump berries without wrinkles for the best color and flavor
- Sweetened condensed milk: the key to creating that creamy texture without any cooking
- Premade graham cracker crust: saves time but you can certainly make your own if preferred
Step-by-Step Instructions
- Blend the Filling:
- Add lemon juice blueberries and condensed milk to your blender. Process until completely smooth with just small flecks of blueberry visible. This creates that gorgeous purple color and ensures the perfect balance of flavors in every bite.
- Fill the Crust:
- Pour your beautiful purple mixture into the graham cracker crust making sure to distribute it evenly. Use a spatula to smooth the top completely. This step is important for presentation and ensures equal thickness throughout.
- Freeze Until Set:
- Place the entire pie in the freezer for about an hour or until the filling becomes solid. The freezing process is what transforms the liquid filling into that amazing ice cream like texture. Keep the pie frozen until right before serving for the perfect consistency.

The magical reaction between the acidic lemon juice and the condensed milk is what makes this recipe work without any cooking. I discovered this pie method from my grandmother who made a similar version with just lemon for her famous easy lemon ice box pie. Adding blueberries takes it to another level of flavor and visual appeal.
Texture Options
This recipe offers versatility in the final texture based on how you choose to chill it. When frozen as directed the pie develops an ice cream like consistency that's refreshing and perfect for hot summer days. If you prefer something softer and more like a custard simply refrigerate instead of freezing. This will take longer to set approximately 3 to 4 hours but creates a completely different dessert experience. Both versions are delicious just different in their final texture.
Seasonal Variations
While blueberries create a stunning purple pie you can adapt this recipe throughout the year using seasonal fruits. Try strawberries for a pink version in spring or blackberries for a deeper purple in late summer. Mixed berries work beautifully too creating a complex flavor profile while maintaining the simple preparation. Just ensure whatever fruit you choose pairs well with the bright lemon flavor and adjust sweetness if using particularly tart fruits.
Make It Fancy
This simple pie can be elevated for special occasions with minimal effort. Once the filling has set add a border of fresh blueberries around the edge or create a decorative pattern across the top. Lemon zest sprinkled over the surface adds both visual appeal and an extra burst of flavor. For a truly impressive presentation add dollops of whipped cream around the edge just before serving and garnish with mint leaves. These small touches make the dessert look like it came from a professional bakery despite taking just minutes to prepare.
