There’s something truly irresistible about the combination of creamy mascarpone and fresh, zesty lemons. This Lemon Tiramisu with Pasteurized Eggs is a sophisticated twist on the beloved Italian classic, offering a silky, luxurious texture and a bright citrus flavor that feels both refreshing and indulgent. Every spoonful is perfectly balanced, with delicate layers of lemon-soaked ladyfingers and rich mascarpone cream that melt effortlessly in your mouth.
What makes this recipe truly special is the use of gently pasteurized egg yolks. Instead of using raw eggs, the yolks are carefully whisked with sugar over a double boiler until they become thick, pale, and velvety. This traditional Italian technique creates a stable, airy cream with an incredibly smooth texture while adding an extra level of food safety. The result is a dessert that tastes authentic, elegant, and wonderfully rich without feeling heavy.
Freshly squeezed lemon juice and fragrant lemon zest bring a vibrant citrus aroma that perfectly complements the creamy mascarpone. Unlike coffee-based tiramisu, this version is light, refreshing, and ideal for warmer months, making it a favorite dessert for spring celebrations, summer gatherings, Easter, Mother’s Day, bridal showers, birthdays, or simply whenever you’re craving something bright and delicious.
Another reason to love this recipe is that it’s completely no-bake and can be prepared a day in advance. In fact, the flavors become even more delicious after an overnight rest in the refrigerator, allowing the ladyfingers to soften beautifully while the mascarpone cream becomes even silkier.
Whether you’re making Lemon Tiramisu for the first time or looking to elevate your favorite Italian dessert, this foolproof recipe delivers bakery-quality results with simple ingredients and timeless techniques. Elegant, creamy, and bursting with fresh lemon flavor, it’s a dessert that’s guaranteed to impress every time.

What Makes This Lemon Tiramisu Special?

Unlike many Lemon Tiramisu recipes that skip the traditional egg base, this version uses gently pasteurized egg yolks to create a rich, silky custard before it’s folded into mascarpone and whipped cream. This classic Italian technique produces a cream that’s lighter, smoother, and far more luxurious than recipes made with whipped cream alone.
Fresh lemon zest and juice bring a vibrant citrus flavor that perfectly complements the rich mascarpone, while the homemade lemon syrup keeps the ladyfingers moist without making them soggy. Every layer is soft, creamy, and beautifully balanced.

Ingredients

For the Lemon Syrup
● 1 cup (240 ml) water
● ⅓ cup (65 g) granulated sugar
● ½ cup (120 ml) freshly squeezed lemon juice
● Zest of 1 large lemon
● 1 teaspoon pure vanilla extract
For the Pasteurized Egg Base
● 3 large egg yolks
● ½ cup (100 g) granulated sugar
For the Mascarpone Cream
● 500 g (17.6 oz) mascarpone cheese, cold
● 1 cup (240 ml) cold heavy whipping cream (35%)
● Zest of 2 large lemons
● 2 tablespoons freshly squeezed lemon juice
● 1 teaspoon pure vanilla extract
● Pinch of fine salt
For Assembly
● 24–28 ladyfingers (Savoiardi)
● Extra lemon zest, for garnish
● Thin lemon slices (optional)
● Fresh mint leaves (optional)
● Powdered sugar (optional)

Instructions

Step 1 – Prepare the Lemon Syrup
In a small saucepan, combine the water and sugar. Bring the mixture to a gentle simmer over medium heat, stirring until the sugar has completely dissolved. Remove from the heat and stir in the fresh lemon juice, lemon zest, and vanilla extract. Set aside and allow the syrup to cool completely before using.
Step 2 – Pasteurize the Egg Yolks
Fill a saucepan with about 1 inch (2.5 cm) of water and bring it to a gentle simmer. Place the egg yolks and sugar in a heatproof bowl set over the saucepan, making sure the bottom of the bowl doesn’t touch the water.
Whisk continuously for 8–10 minutes until the mixture becomes pale, thick, and fluffy and reaches 160°F (71°C). Remove from the heat and let it cool to room temperature.
Step 3 – Prepare the Mascarpone Filling
In a large mixing bowl, beat the cold mascarpone until smooth and creamy.
Gradually mix in the cooled pasteurized egg mixture until fully incorporated.
Add the lemon zest, fresh lemon juice, vanilla extract, and a pinch of salt.
In a separate bowl, whip the heavy cream to medium peaks. Using a spatula, gently fold the whipped cream into the mascarpone mixture until no streaks remain. Be careful not to overmix to keep the filling light and airy.
Step 4 – Assemble the Tiramisu
Quickly dip each ladyfinger into the cooled lemon syrup for 1–2 seconds. Arrange a single layer of soaked ladyfingers in the bottom of an 8×8-inch (20×20 cm) baking dish.
Spread half of the mascarpone filling evenly over the ladyfingers.
Repeat with another layer of dipped ladyfingers, then spread the remaining mascarpone cream on top. Smooth the surface with an offset spatula or the back of a spoon.
Step 5 – Chill
Cover the dish tightly with plastic wrap and refrigerate for at least 8 hours, preferably overnight. This resting time allows the flavors to develop and gives the tiramisu its signature creamy texture.
Step 6 – Garnish and Serve
Just before serving, garnish with fresh lemon zest, thin lemon slices, a few fresh mint leaves, and a light dusting of powdered sugar if desired.
Serve chilled and enjoy every creamy, citrusy bite!
