Gather Your Ingredients for Lemon Tiramisu
Alright, let’s get our mise en place ready! This Lemon Tiramisu is all about layering those bright, creamy flavors, so make sure you have everything handy. We’ll break it down by what we’re making.
First up, for that luscious Lemon Curd:
- 4 large egg yolks
- 4 large eggs (yes, the whole thing!)
- 1/4 teaspoon sea salt
- 1 1/4 cups granulated sugar
- Zest from 2 lemons – get all those fragrant oils!
- 2/3 cup freshly squeezed lemon juice (that’s about 2-3 juicy lemons)
- 1/2 cup unsalted butter, cubed
Next, for the Zesty Lemon Syrup (the fun part for soaking!):
- 1/2 cup water
- 1/4 cup granulated sugar
- 1 lemon, peeled and juiced (save the peel for the curd!)
- 1 sprig of fresh basil (optional, but totally wakes it up!)
- 1/4 cup limoncello (also optional, but oh-so-dreamy!)
Now, for the creamy Filling:
- 1 1/2 cups cold heavy whipping cream
- 1 1/2 cups lemon curd (about half of what you make, chilled!)
- 1 lb mascarpone cheese, softened to room temperature (this is key for smoothness!)
And finally, for the Assembly:
- 2 packs ladyfingers (grab your favorite kind, keto or regular!)
- Pretty lemon slices for decorating
Crafting the Perfect Lemon Curd for Your Lemon Tiramisu
Okay, let’s get down to business and make that glorious lemon curd! This is where the magic really starts, and trust me, it’s easier than you think. The key here is patience and constant motion. You’ll want to grab a medium saucepan and whisk together your egg yolks, the whole eggs, that pinch of sea salt, sugar, zesty lemon zest, and the fresh lemon juice. Give it a good whisk until it’s all combined.
Now, place that saucepan over medium heat. This is where the whisking becomes your best friend! You need to stir constantly, making sure nothing sticks to the bottom. Once it starts to simmer – and you’ll know because it’ll get a bit bubbly – keep whisking for about a minute. You’ll feel it start to thicken up.
Here’s a little trick for that super silky smooth texture: pour the thickened curd through a fine-mesh strainer into a non-metal bowl. This catches any bits of zest or cooked egg bits, giving you pure, velvety goodness. Now, add in your cubed butter. Let it sit for just a minute to start melting, then stir it in until it’s completely melted and the curd is glossy and smooth. To get it perfectly chilled and ready for our tiramisu, cover it with a piece of parchment paper right on the surface (this stops a weird skin from forming!) and pop it in the fridge. It needs to chill and get nice and thick, which usually takes at least a couple of hours.
Preparing the Zesty Lemon Syrup
While that gorgeous lemon curd is chilling, let’s whip up the lemon syrup! This is what’s going to give our ladyfingers that lovely, subtle citrus flavor and just the right amount of moisture. It’s super simple – grab another little saucepan and combine the water, sugar, the juice from *one* lemon (you can use the peeled lemon from earlier!), and that optional sprig of basil if you’re feeling fancy.
Bring this mixture to a gentle simmer over medium heat, just letting it bubble a little until the sugar dissolves completely. Once it’s all dissolved and fragrant, take it off the heat and let it cool down. When it’s completely cooled, just strain out those lemon peels and the basil. If you’re adding the limoncello for an extra grown-up kick, stir it in now. This syrup is key for that perfect soak – you don’t want your ladyfingers to turn to mush, just absorb that lovely flavor!
Assembling Your Delicious Lemon Tiramisu
Alright, the moment we’ve all been waiting for! It’s time to bring everything together and create this stunning Lemon Tiramisu. Seriously, as you start layering, the kitchen fills with this incredible aroma of creamy mascarpone and bright lemon – it’s like bottling up sunshine, just like I remember it! So, grab your serving dish – an 8×8 inch or a nice glass dish works perfectly.
First things first, let’s get those ladyfingers ready. You want to give them a quick dip in that zesty lemon syrup we made. Don’t let them soak for too long, or they’ll get soggy! Just a quick dunk on each side, and then arrange them in a single layer on the bottom of your dish. Try to fit them in snugly.
Next up is that heavenly filling. Remember how we gently folded the whipped cream into the lemon and mascarpone mixture? That’s so important to keep it light and airy! Spread about half of this gorgeous filling evenly over the ladyfinger layer. It should be smooth and creamy. Then, repeat! Dip another batch of ladyfingers and lay them on top of the filling. Finish by spreading the remaining filling all over, making sure to cover those ladyfingers completely. Smooth it out with your spatula.
Now for the hardest part: waiting! Cover this beauty with plastic wrap and pop it into the refrigerator. It needs at least 2 hours to chill and let all those flavors meld together. Honestly, overnight is even better if you can resist the temptation! This chilling time is crucial for the tiramisu to set up properly, making it sliceable and perfectly delicious.

Tips for the Best Lemon Tiramisu
Okay, so you’ve got the recipe, and you’re ready to whip up some magic! But just to make *sure* this Lemon Tiramisu is absolutely, positively spectacular, let me share a few little secrets I’ve picked up along the way. It’s all about those small details that make a big difference, you know?
First off, ingredient temperature is your friend. Make sure that mascarpone cheese is *really* at room temperature. If it’s too cold, it’ll be lumpy, and nobody wants a lumpy tiramisu. Conversely, your heavy cream needs to be super cold for it to whip up properly into those lovely stiff peaks. It’s like a little dance between warm and cold!
Also, when you’re mixing the mascarpone and lemon curd, be gentle! Seriously, don’t go crazy with the mixer. Overmixing can make the mascarpone get a bit… well, gritty. Just stir until it’s smooth and happy. And for those ladyfingers? A quick dip is all they need! We want them soaked but not falling apart. You can always add more syrup if you think they need it, but never too much at once. I learned that the hard way experimenting with low-carb versions, trying to get the texture just right so they don’t disintegrate.

Frequently Asked Questions about Lemon Tiramisu
Got questions about making this sunny Lemon Tiramisu? I’ve got answers! It’s totally normal to wonder about a few things when you’re trying a new twist on a classic, so let’s clear those up!
Can I make this Lemon Tiramisu ahead of time?
Oh, absolutely! In fact, I highly recommend it. This dessert actually gets *better* when it has time to chill in the fridge for at least 2 hours, or even overnight. All those flavors get to mingle and deepen, and the ladyfingers soften up perfectly. It’s the ideal make-ahead dessert for parties!
What are some good substitutions for ladyfingers?
If you’re going keto or just can’t find ladyfingers, no worries! You can totally use keto-friendly ladyfingers or even slices of a low-carb pound cake. Just make sure they’re not too thick, so they can soak up that delicious lemon syrup nicely. You can find some great options for keto-friendly desserts that might give you other ideas too!
Can I skip the limoncello?
Yes, you absolutely can! The limoncello adds a lovely extra layer of lemony depth and a little boozy kick, but it’s totally optional. The tiramisu will still be wonderfully lemony and delicious without it. For an alcohol-free version, just leave it out – maybe add an extra splash of lemon juice to the syrup if you want!
How should I store leftover Lemon Tiramisu?
Keep any leftovers covered tightly in the refrigerator. Because of the mascarpone and cream, it’s best to enjoy it within about 2-3 days. It’s so popular, though, I doubt you’ll have any leftovers!

Lemon Tiramisu
Ingredients
Equipment
Method
- If using store bought lemon curd you will need 2 ½ cups, 725g, or 26oz by weight.In a medium saucepan, combine egg yolks, whole eggs, salt, sugar, lemon zest, and lemon juice. Whisk to combine.
- Heat on medium heat, whisking or stirring constantly. Let the lemon curd come to a simmer and thicken – approximately one minute after simmering.
- Once thickened, strain the curd through a wire strainer or cheesecloth to remove the zest and any lumps. Transfer to a non-metal heat safe bowl. Add butter to the curd and let sit for a minute to melt. Stir until fully melted and smooth.
- Cover with a piece of parchment paper or wrap placed directly on the surface and refrigerate until cold and thickened.
- While the lemon curd chills, prepare the lemon syrup. Combine water, sugar, lemon juice, peeled lemon zest, and basil (optional).
- Bring to a simmer on medium heat and let cool. Once cooled, strain out the lemon peels and set aside in a bowl for later. If using limoncello, add it in at this point.
- Chill your mixing bowl and whisk in the freezer for 5 minutes. Pour heavy whipping cream into the chilled mixing bowl and whip to stiff peaks (using an electric mixer).
- In a large bowl, combine half of the cooled lemon curd (set aside the other half in the fridge) and all of the mascarpone cheese. Whisk until fully combined and smooth. Do not overmix or the mascarpone will become gritty.
- Add whipped cream into the lemon curd mixture. Gently fold with a whisk or spatula to combine, being careful not to deflate the whipped cream.
- Dip ladyfingers briefly into the cooled lemon syrup. Arrange a layer of soaked ladyfingers in the bottom of your serving dish. Spread half of the mascarpone-lemon filling over the ladyfingers.
- Repeat with another layer of soaked ladyfingers and the remaining filling. Cover and refrigerate for at least 2 hours, or until firm.
- Decorate with lemon slices before serving.
