Lemon Tiramisu brings a bright citrusy twist to the classic Italian dessert. Layers of delicate ladyfingers are soaked in homemade lemon syrup then stacked with tangy lemon curd and a billowy mascarpone cream for a refreshing treat that is perfect for spring or summer gatherings. Every bite feels like a taste of sunshine and the chill time makes it melt-in-your-mouth soft.

My first time making this was for my partner’s birthday and now it is the most requested dessert among my friends during warm weather picnics. It never fails to impress even those who claim they do not like lemon.

Ingredients

  • Freshly squeezed lemon juice and zest: Brings a bright citrus note Select firm lemons with glossy skin for best juice and zest
  • Granulated sugar: Provides sweetness and helps build structure in syrup and curd Opt for fine sugar for smooth mixing
  • Egg yolks and whole egg: Creates the rich velvety body of the curd Use large eggs and check freshness
  • Unsalted butter: Adds creaminess and shine to the lemon curd Look for European style for extra richness
  • Mascarpone cheese: Gives that classic tiramisu silkiness Buy high quality mascarpone from a reputable dairy case and keep it cold until use
  • Heavy cream: Whips up light fluffy layers for the mascarpone filling Choose full fat for best texture and volume
  • Savoiardi ladyfingers: Soft but sturdy base that soaks up the lemon syrup Classic Italian imported brands maintain their structure best
  • Vanilla: Enhances the filling and rounds out the lemon tang A splash of pure vanilla extract makes a big difference
  • Salt: Balances sweetness in lemon curd Use just a pinch to highlight flavors

I always love using lemon zest in desserts because of the fragrant oils it brings It makes me think of helping my grandmother zest fruit for her Sunday cakes The savory aroma fills my kitchen and instantly brings me back

Storage Tips

Once assembled lemon tiramisu should be covered tightly and kept cold in the fridge It is best eaten within three days as the delicate ladyfingers get softer over time Individual slices hold their shape best if sliced straight from the chilled pan Use a thin spatula for neat servings and if you want to make it ahead prepare the separate layers and only assemble the day before

Ingredient Substitutions

If you cannot find mascarpone substitute a combination of softened cream cheese and a few spoons of heavy cream to mimic the texture For the ladyfingers you can use soft store bought sponge cake sliced into fingers Fresh Meyer lemons bring a slightly floral flavor if you would like to experiment Also store bought lemon curd can work for an easy shortcut though homemade is noticeably better

Serving Suggestions

Serve lemon tiramisu as a cool refreshing finish after a summer barbecue or picnic Individual jars or cups make beautiful single servings for parties Top each portion with thin curls of lemon zest or fresh berries for a bright burst I often garnish mine with a tiny sprig of mint for color and aroma

Recipe FAQs

→ How do I prevent soggy ladyfingers?

Quickly dip each ladyfinger in lemon syrup—just a second or two is enough. Avoid letting them sit too long, as they absorb liquid quickly.

→ Can I make lemon curd in advance?

Yes, you can prepare the lemon curd up to two days before assembling. Store it tightly covered in the refrigerator.

→ Can mascarpone be substituted?

Full-fat cream cheese is the closest substitute, though it will alter the flavor and texture slightly.

→ How long does the dessert need to chill?

For best results, chill for at least 6 hours. This allows the flavors to meld and layers to firm up for easy slicing.

Steps

Step 01

Combine lemon juice, water, sugar, and lemon zest in a medium saucepan over medium-high heat. Simmer while occasionally stirring until sugar dissolves and mixture reduces slightly, approximately 5 minutes. Remove from heat, strain through a fine-mesh sieve into a shallow bowl, and refrigerate until cooled.

Step 02

In a medium saucepan, whisk together egg yolks, whole egg, and sugar until combined. Stir in lemon juice, zest, and salt. Add butter pieces and cook over medium-low heat, stirring continuously, until the mixture thickens, approximately 5-8 minutes. Strain through a fine-mesh sieve into a medium bowl, cover with plastic wrap, and refrigerate until fully cooled.

Step 03

Using a stand mixer with a whisk attachment, whip heavy cream to stiff peaks. Transfer whipped cream to a separate bowl. Replace the whisk attachment with a paddle attachment. Beat together mascarpone cheese, sugar, lemon syrup, and vanilla extract on high until well combined. Add 1 cup of whipped cream to the mixture and beat until incorporated, then gently fold in the remaining whipped cream.

Step 04

Quickly dip each ladyfinger into the prepared lemon syrup, ensuring they are soaked but not soggy. Arrange in two rows of six along the bottom of an 8-inch square dish. Spread half of the lemon curd evenly over the ladyfingers, followed by half of the mascarpone filling. Repeat with another layer of syrup-soaked ladyfingers, the remaining lemon curd, and half of the remaining mascarpone filling. Pipe the rest of the mascarpone filling on top using a pastry bag or a ziplock bag with the corner cut off. Cover and refrigerate for at least 6 hours before serving.
