Lemon Ricotta Strawberry Pie with Poppy Seed Shortbread Crust Recipe
A scientifically optimized lemon ricotta strawberry pie featuring a crisp poppy seed shortbread crust and a perfectly set, silky ricotta custard.
- Draining the ricotta overnight removes excess whey, preventing the custard from weeping and ensuring a dense, velvety texture.
- Blind baking the poppy seed shortbread crust sets the starch barrier, keeping the base crisp under the wet filling.
- Cornstarch acts as a thermal stabilizer, raising the coagulation temperature of the egg proteins to prevent curdling.
The secret to a flawless lemon ricotta strawberry pie lies in controlling moisture migration between the wet custard and the crisp crust. We achieve this by utilizing a high-fat shortbread base infused with poppy seeds.
Excess water is the enemy of custard.
To prevent a watery filling, you must drain the ricotta cheese to remove excess whey. When baked, the proteins in the ricotta and eggs coagulate to form a stable protein matrix. Adding a small amount of cornstarch acts as a thermal stabilizer, preventing the egg proteins from curdling. This scientific approach to moisture control is also why we balance wet and dry ratios in our Strawberry Greek Yogurt Banana Bread.
Blind baking the crust at 350°F (177°C) is non-negotiable. This step initiates the Maillard reaction, developing complex nutty flavors.
The strawberry topping relies on maceration, a process where sugar draws out water from the fruit via osmosis. This concentrates the natural strawberry flavors and creates a glossy, self-glazing syrup. If you enjoy this flavor profile, you will appreciate the strawberry syrup technique detailed in our Strawberry and Mascarpone Crepes with Strawberry Syrup.
Lemon Ricotta Strawberry Pie with Poppy Seed Shortbread Crust
Ingredients
- 1.5 cups (180g) King Arthur Unbleached All-Purpose Flour
- 1/3 cup (40g) powdered sugar
- 1.5 tablespoons poppy seeds
- 1/2 cup (113g) unsalted butter, cold and cubed
- 1/4 teaspoon Diamond Crystal Kosher Salt
- 1 large egg yolk
- 15 ounces (425g) whole milk ricotta cheese, drained overnight
- 1/2 cup (100g) granulated sugar
- 2 large eggs, room temperature
- Zest of 2 organic lemons
- 2 tablespoons fresh lemon juice
- 1 tablespoon cornstarch
- 1 teaspoon pure vanilla extract
- 2 cups fresh strawberries, hulled and sliced
- 2 tablespoons granulated sugar (for strawberries)
- 1 teaspoon fresh lemon juice (for strawberries)
Directions
- Place the whole milk ricotta in a fine-mesh sieve lined with cheesecloth over a bowl, weigh it down, and let it drain in the refrigerator for at least 4 hours, preferably overnight.
- In a food processor, combine the King Arthur flour, powdered sugar, poppy seeds, and Diamond Crystal salt, then pulse to combine.
- Add the cold cubed butter and pulse until the mixture resembles coarse sand, then add the egg yolk and pulse until the dough begins to clump together.
- Press the dough evenly into the bottom and up the sides of a 9-inch tart pan with a removable bottom, then freeze the crust for 20 minutes to solidify the butter fats.
- Preheat the oven to 350°F (177°C), line the chilled crust with parchment paper, fill with pie weights, and bake for 15 minutes.
- Remove the weights and parchment, bake for an additional 8 to 10 minutes until the bottom is dry and lightly golden, then let cool completely.
- In a large bowl, whisk the drained ricotta, granulated sugar, eggs, lemon zest, lemon juice, cornstarch, and vanilla extract until completely smooth and emulsified.
- Pour the ricotta filling into the cooled shortbread crust and bake at 350°F (177°C) for 30 to 35 minutes, or until the edges are set but the center retains a slight, uniform jiggle.
- Cool the pie to room temperature, then chill in the refrigerator for at least 3 hours to set the custard.
- Thirty minutes before serving, toss the sliced strawberries with granulated sugar and lemon juice in a bowl to macerate at room temperature, then spoon over the chilled pie just before slicing.
Notes
Following these precise parameters ensures structural integrity and optimal texture.
- Use King Arthur Unbleached All-Purpose Flour for the crust; its precise 11.7% protein content provides the perfect balance of structural integrity and tenderness compared to lower-protein national brands.
- Draining the ricotta is essential because excess whey water will vaporize during baking, creating steam pockets that cause the custard to puff up and subsequently collapse into a cracked surface.
- If you skip chilling the pressed crust in the freezer before baking, the butter fats will melt too quickly in the oven, causing the crust to shrink down the sides of the pan. Prevent this by freezing the crust for a full 20 minutes.
- After 24 hours in the refrigerator, the shortbread crust will begin to absorb moisture from the ricotta filling, gradually losing its crisp texture and becoming soft.
- If you do not have a tart pan with a removable bottom, a standard 9-inch glass pie dish works as a backup; however, you must increase the initial blind-baking time by 3 minutes to account for the slower heat transfer of glass.
Serving Suggestions
Serve this pie chilled to ensure the ricotta custard maintains its clean, sliceable structure. The contrast of cold, creamy filling against a crisp crust is enhanced by these specific pairings:
- A dollop of unsweetened whipped cream (to balance the bright acidity of the lemon and strawberries).
- Fresh mint leaves (to add a clean, herbaceous aroma that cuts through the richness of the whole milk ricotta).
- A glass of chilled Moscato d'Asti (the light effervescence and sweet stone fruit notes harmonize beautifully with the citrus custard).
- A dusting of powdered sugar right before slicing (for a sharp visual contrast against the vibrant red strawberries).
Storage and Reheating
Store any leftover pie in the refrigerator, loosely covered with plastic wrap or stored in an airtight pie container, for up to 3 days. Keep it in the main body of the fridge rather than the door to maintain a constant cold temperature.
Freezing this pie is highly discouraged.
The freezing process causes the water molecules in the ricotta custard to expand into ice crystals, which will rupture the delicate protein emulsion and result in a spongy, weeping mess upon thawing.
This pie is designed to be served cold or at room temperature. Do not attempt to reheat the assembled pie, as heat will melt the fresh strawberry topping and cause the custard to lose its firm structure.
You can easily prepare the shortbread crust and the ricotta filling 24 hours in advance. Keep the baked crust wrapped tightly at room temperature and store the raw filling in an airtight container in the fridge, then assemble and bake on the day of serving.
Ingredient Substitutes
If you need to adapt this recipe, ensure you maintain the balance of fat and moisture to preserve the pie's structural integrity.
- Ricotta substitute: Swap the drained ricotta with an equal weight of drained cottage cheese processed in a blender until completely smooth.
- Poppy seed substitute: Use black sesame seeds in a 1:1 ratio to maintain the visual contrast and nutty undertones in the shortbread crust.
- Strawberry substitute: Replace the strawberries with fresh raspberries or blackberries using a 1:1 ratio, adjusting the maceration sugar slightly depending on the fruit's natural sweetness.
Mastering this pie is a masterclass in moisture management and temperature control. By respecting the science of draining the cheese and blind baking the crust, you will achieve a professional-grade dessert every single time. Enjoy the clean, bright flavors of this perfectly balanced pastry.
