Grapefruit Pie is a refreshing baked dessert that combines the tangy flavor of fresh grapefruit with a smooth, creamy filling and a buttery crust. This pie offers a unique twist on classic citrus desserts, delivering a perfect balance between sweet, tart, and slightly bitter notes. Light yet indulgent, it’s an excellent choice for spring gatherings, summer treats, or anyone who loves elegant fruit-based desserts.
Unlike traditional lemon or lime pies, grapefruit pie stands out for its vibrant color and sophisticated flavor profile. The creamy filling sets beautifully after baking, creating a silky texture that pairs perfectly with a crisp pie crust.
Ingredients
For the Crust
- 1 deep-dish pie crust (homemade or store-bought)
For the Filling
- 1 can (14 oz / 397 g) sweetened condensed milk
- 4 large egg yolks
- ½ cup fresh grapefruit juice
- 1 tablespoon grapefruit zest
For the Topping (Optional)
- 1 to 2 fresh grapefruits, peeled and segmented
- Whipped cream for serving
Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 350°F (180°C). Place the pie crust into a deep pie dish if it isn’t already shaped.
2. Blind Bake the Crust
Line the crust with parchment paper and fill with pie weights or dried beans. Bake for about 10 minutes, then remove the weights and bake for another 5 minutes until lightly golden. Let it cool slightly.
3. Prepare the Grapefruit Filling
In a large mixing bowl, whisk together the sweetened condensed milk and egg yolks until smooth and creamy. Add the grapefruit zest, then slowly pour in the fresh grapefruit juice while whisking continuously. The mixture will begin to thicken slightly.
4. Fill the Pie
Pour the citrus filling into the pre-baked crust and smooth the top with a spatula.
5. Bake
Bake the pie for 25 to 30 minutes, or until the edges are set and the center still has a slight jiggle. Avoid overbaking to keep the texture creamy.
6. Cool and Chill
Remove the pie from the oven and let it cool at room temperature. Once cooled, refrigerate for at least 4 hours, or until fully set. Chilling helps the filling firm up and enhances the flavor.
7. Add the Topping
Before serving, arrange fresh grapefruit segments on top of the pie. You can also add a layer of whipped cream for extra sweetness and decoration.

Flavor and Texture
Grapefruit pie has a smooth, custard-like consistency with a bright citrus flavor. The condensed milk creates richness, while the grapefruit juice adds freshness and a gentle tang. Each bite offers a contrast between the creamy filling and the crisp crust, making it both refreshing and satisfying.
Tips for Success
- Use fresh grapefruit juice for the best flavor and natural aroma.
- Zest the grapefruit before cutting it to make the process easier.
- Chill the pie thoroughly before slicing to achieve clean pieces.
- Ruby red grapefruits give a sweeter taste and a beautiful pink color.
Variations
- Try a graham cracker crust for a sweeter, crumbly texture.
- Add a light meringue topping for a bakery-style finish.
- Mix grapefruit with a little lemon or lime juice for a more complex citrus flavor.
Serving Suggestions
Serve grapefruit pie cold, straight from the refrigerator. It pairs wonderfully with whipped cream, fresh berries, or a light dusting of powdered sugar. This pie can be prepared a day in advance, making it a convenient dessert for gatherings or special occasions.
