Lemon Blueberry Lasagna

My neighbor brought a version of this to a block party one July and I literally could not stop going back for seconds. The combination of tart lemon and sweet blueberries nestled between soft cookie layers caught me totally off guard. I begged her for the recipe that same evening while standing in her driveway.

I made it for my in-laws the following weekend and my mother in law who rarely compliments anything asked for the recipe before she even finished her slice. That is when I knew this one was a permanent fixture in my rotation.

Ingredients

• 300 g vanilla wafer cookies, crushed: These form the tender base and I have found vanilla wafers give a softer more delicate bite than graham crackers here
• 80 g unsalted butter, melted: Just enough to hold the crust together without making it greasy
• 300 g fresh or frozen blueberries: Frozen work perfectly fine since they break down in the sauce anyway
• 60 g granulated sugar: Balances the tartness of the berries without turning them into jam
• 2 tbsp lemon juice: Adds brightness to the blueberry layer
• 2 tbsp water: Helps the berries start cooking before they release their own juices
• 2 tsp cornstarch: The secret to getting that beautiful thick sauce instead of a runny mess
• 300 g cream cheese, softened: Must be truly soft or you will fight lumps the entire time
• 200 g powdered sugar: Dissolves smoothly into the cream cheese without any grittiness
• 2 tbsp lemon zest: This is where all the aromatic lemon punch comes from so do not skip it
• 4 tbsp lemon juice: Keeps the cream layer tangy and prevents it from tasting like plain frosting
• 400 ml heavy whipping cream, cold: Cold cream whips faster and holds its shape better when folded in
• 100 g whipped cream and garnishes: The finishing touch that makes it look bakery worthy

Instructions

Build the cookie base:

Toss the crushed cookies with melted butter until every piece is coated then press firmly into your 23x33 cm dish. Pop it in the fridge to set while you work on the fruit.

Cook the blueberry sauce:

Combine blueberries sugar lemon juice and water in a saucepan over medium heat and wait for those berries to burst open. Whisk the cornstarch with a splash of water into a slurry then stir it in and simmer until the whole thing turns glossy and thick about two minutes.

Whip up the lemon cream:

Beat the softened cream cheese and powdered sugar until completely smooth then mix in the lemon zest and juice. In another bowl whip the cold heavy cream to stiff peaks and gently fold it into the lemon mixture being careful not to deflate it.

Layer everything together:

Spread half the lemon cream over the chilled crust then spoon half the cooled blueberry sauce on top. Repeat both layers and you will see those gorgeous purple streaks running through the cream.

Let it rest:

Cover the dish and refrigerate for at least four hours or overnight if you can stand the wait.

Finish and serve:

Spread whipped cream over the top and scatter fresh blueberries and a pinch of lemon zest across the surface right before slicing.

Pin it

There is something almost magical about pulling this out of the fridge the next morning seeing those distinct layers through the glass dish. It became the dessert I bring to every potluck where I want people to actually remember what I brought.

Getting the Layers Right

The trick to clean layers is spreading each one gently without dragging the spoon through the previous layer. I drop small dollops across the surface first then use the back of a spoon to connect them.

Making It Ahead

This dessert actually improves after a full night in the fridge because the cookie layer softens and absorbs some of the cream. I always make it the evening before any event and it has never failed me.

Serving Suggestions and Substitutions

Swap in gluten-free cookies to make this work for almost anyone at the table and honestly nobody will notice the difference. Mascarpone instead of cream cheese gives a softer more Italian pastry shop feel if you want to switch things up.

• A cold glass of sparkling wine pairs surprisingly well with the tartness
• Lemonade on the side makes it feel like a full summer experience
• Cut it with a hot knife for the cleanest squares

Pin it

This is the kind of dessert that makes people close their eyes when they take the first bite. Keep it in your back pocket and pull it out when you really want to impress someone.

Recipe FAQs

→ Can I use frozen blueberries instead of fresh?

Yes, frozen blueberries work perfectly. Cook them straight from frozen — the sauce will thicken just the same once the cornstarch slurry is added.

→ How long does this need to chill before serving?

At least 4 hours in the refrigerator. Overnight chilling yields the firmest, cleanest slices and the best flavor meld.

→ Can I make it gluten-free?

Absolutely. Swap the vanilla wafer cookies for any certified gluten-free cookie or graham cracker alternative.

→ What can I substitute for cream cheese?

Mascarpone is an excellent choice for a milder, slightly sweeter flavor. Full-fat Greek yogurt works too but will produce a tangier result.

→ How should I store leftovers?

Cover the dish tightly with plastic wrap and keep refrigerated for up to 4 days. The layers hold their structure well after the initial chill.

→ Can I prepare it in advance for a party?

It's ideal for making ahead. Assemble and chill overnight, then add the whipped cream topping and garnish just before serving for the freshest presentation.
