This Lemon Blueberry Tart has everything I want in a spring dessert: a buttery shortbread crust that crumbles just right, a creamy lemon filling that makes your mouth water, and swirls of homemade blueberry sauce running through it like little purple ribbons. I first made this tart for a friend’s bridal shower last April, and honestly, I’ve been making it on repeat ever since. It looks fancy enough for special occasions but comes together with simple ingredients you probably already have.

Why You’ll Love This Lemon Blueberry Tart
This citrus dessert Lemon Blueberry Tart checks so many boxes. It’s make-ahead friendly, which means you can bake it the day before and let it chill overnight (actually, it tastes even better the next day). The shortbread tart crust is super forgiving and doesn’t require any rolling or chilling before baking. And the lemon curd style filling? You just whisk everything together and pour it in. No double boiler, no constant stirring.
It’s also beautiful. The Lemon Blueberry Tart effect looks like you spent hours on it, but really, you just dropped some sauce on top and dragged a toothpick through it. Guests always think I fussed over this dessert way more than I actually did.

Lemon Blueberry Tart Ingredients
Here’s what you’ll need to make this Lemon Blueberry Tart with blueberries.
See Recipe Card Below This Post For Ingredient Quantities
Blueberry Sauce
Cornstarch: Thickens the blueberry sauce so it holds its shape when swirled into the filling instead of sinking to the bottom.
Lemon juice (or water): Helps dissolve the cornstarch smoothly and adds a little extra tang to the sauce.
Fresh or frozen blueberries: Either works great here. Frozen blueberries actually hold their shape well and release just the right amount of juice as they cook.
Granulated sugar: Sweetens the berries and helps them break down into a jammy sauce.
Shortbread Crust
Unsalted butter, melted: Creates that rich, crumbly shortbread texture. Melting the butter makes the dough easy to press into the pan without any rolling.
Granulated sugar: Adds sweetness and helps the crust bake up tender and golden.
Pure vanilla extract: Gives the Lemon Blueberry Tart crust a warm, subtle flavor that complements the lemon filling.
Salt: Balances the sweetness and brings out all the other flavors.
All-purpose flour (spooned & leveled): Forms the structure of the crust. Spooning and leveling prevents packing too much flour, which keeps the crust tender.
Filling
Full-fat sweetened condensed milk: This is what makes the filling so creamy and smooth without any fuss. It’s already sweetened, so you don’t need extra sugar.
Lemon juice : Provides that bright, tangy flavor and helps thicken the filling as it bakes.
Lemon zest : Adds extra lemon flavor and a little texture. Fresh zest makes a big difference here.
Large egg yolk: Helps bind everything together and gives the filling a silky, custard-like texture.
Optional Garnishes
Lemon slices: Pretty and fresh looking on top of each slice.
Blueberries: A few fresh berries scattered on top add color and a nice pop of tartness.
Leftover blueberry sauce: Drizzle extra sauce over each slice for even more blueberry flavor.
Whipped cream: A dollop of whipped cream balances the tangy lemon and adds a light, airy contrast.
How To Make Lemon Blueberry Tart
Let’s walk through making this homemade Lemon Blueberry Tart step by step.
Make the Blueberry Sauce: Using a fork, mix the cornstarch and lemon juice together in a small bowl until the cornstarch has dissolved completely. Set it aside for now. In a small saucepan over medium heat, warm the blueberries and sugar together. Stir occasionally for about 3 minutes, mashing the blueberries against the bottom and sides of the pan to help them break up. Stir in the cornstarch mixture and cook for 2 more minutes as the sauce thickens, mashing the berries to your liking.
Some people like chunky sauce, some like it smoother. Remove from heat and set aside at room temperature until you’re ready to swirl it in later. You’ll end up with about ½ to ⅔ cup of sauce, and you’ll use about half for the swirl. Save the rest for serving.
Preheat Oven: Preheat your oven to 350°F (177°C).
Prepare the Crust: In a medium bowl, mix the melted butter, sugar, vanilla extract, and salt together until combined. Add the flour and stir until everything comes together. The dough will feel a little greasy and very thick, almost like cookie dough. Using a silicone spatula or your hands, press the dough firmly into a 9-inch tart pan. You don’t need to grease the pan. Make sure the layer is even on the bottom and all around the sides, pressing it up the edges.
Bake the Crust: Bake for 15 minutes, or until the edges turn very lightly golden. Remove from the oven and use a fork to poke a few holes all over the warm crust (don’t poke all the way through to the bottom). This helps the filling stick and prevents any air bubbles.
Make the Filling: Whisk all of the filling ingredients together in a bowl until smooth and combined. Pour the mixture into the warm crust right away. The warmth helps everything settle in nicely.
Swirl the Blueberry Sauce: Give your blueberry sauce a stir since it may have thickened as it cooled. If it’s too thick to drizzle, warm it in the microwave for 5 to 10 seconds. Drop spoonfuls of the sauce all over the top of the lemon filling, using about half of what you made. Using a toothpick or the tip of a knife, gently swirl the sauce and filling together in whatever pattern you like. Shimmy the pan back and forth 2 to 3 times to help the filling settle and smooth out.
Bake the Tart: Bake for 17 to 19 minutes, just until the center no longer jiggles when you lightly tap the pan. The top will still look a little sticky and soft. Don’t over-bake it or the filling can crack or get grainy.
Cool & Chill: Remove the tart from the oven and let it cool completely at room temperature on a cooling rack. Once cool, chill it uncovered in the refrigerator for at least 2 hours. You can leave it up to a full day. If you’re chilling it longer than 2 hours, cover it loosely with plastic wrap.
Serve: If your tart pan has removable sides, pop them off for a clean presentation. Slice the tart into wedges and serve with any optional garnishes you like, plus a drizzle of that reserved blueberry sauce.
Smart Substitutions
No tart pan? Use a 9-inch pie dish instead. The crust might be a little thinner on the sides, but it’ll still work beautifully.
Can I use bottled lemon juice? Fresh lemon juice really does taste better here, but bottled will work in a pinch. Just use the same amount.
What about lime? You can swap lemon for lime if you want a different citrus vibe. The filling will taste slightly more tropical and less tangy.
Gluten-free option: Use a 1-to-1 gluten-free flour blend in the crust. The texture might be slightly more crumbly, but it’ll still taste great.
Dairy-free: This one’s tricky since the filling relies on sweetened condensed milk. You can try a dairy-free condensed milk alternative, though I haven’t tested it myself.
Equipment For Lemon Blueberry Tart
Here’s what makes this baked Lemon Blueberry Tart come together easily:
Small saucepan: For cooking the blueberry sauce.
Mixing bowls: One medium for the crust, one for the filling.
Whisk: Gets the lemon filling nice and smooth.
Silicone spatula: Helps press the dough into the pan evenly.
Fork: For poking holes in the warm crust.
Toothpick or knife: For creating those pretty blueberry swirls.
9-inch tart pan (with or without removable sides): A removable bottom makes serving easier, but either works.
Cooling rack: Lets air circulate under the tart as it cools.
How to Store This Lemon Blueberry Tart
Refrigerator: Cover leftovers tightly with plastic wrap or foil and store in the fridge for up to 1 week. The Lemon Blueberry Tart actually tastes better after a day or two as the flavors meld together.
Freezer: This spring dessert Lemon Blueberry Tart freezes beautifully. Once it’s completely cooled and chilled, wrap it well in plastic wrap and then foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before slicing and serving.
Make-ahead tip: You can bake this Lemon Blueberry Tart a full day ahead and keep it chilled until you’re ready to serve. Just remember, the filling must be poured into a warm crust, so don’t try to pre-bake the crust ahead of time and cool it.
Expert Tips
Use room temperature ingredients for the filling: Let your egg yolk sit out for a few minutes before whisking. It blends more smoothly.
Don’t skip poking the crust: Those little fork holes really do help the filling stick and prevent bubbles from forming under the surface.
Watch the bake time closely: Over-baking makes the filling grainy and can cause cracks. As soon as the center stops jiggling, pull it out.
Let it chill fully: I know it’s tempting to dig in right away, but this tart needs time to set in the fridge. Two hours minimum. Overnight is even better.
Save extra blueberry sauce: That leftover sauce is liquid gold. Drizzle it over each slice, or save it for topping yogurt or pancakes later in the week.
FAQ
Can you make a Lemon Blueberry Tart the day before?
Yes, and I actually recommend it. This Lemon Blueberry Tart recipe tastes even better after chilling overnight. The flavors have time to come together, and the texture sets up perfectly. Just cover it loosely after the first 2 hours of chilling.
How long to cook blueberry tarts?
This tart bakes in two stages: the crust bakes for 15 minutes, then the filled tart bakes for 17 to 19 minutes. Total oven time is about 32 to 34 minutes, but the tart needs at least 2 hours of chilling time in the fridge before serving.
How long does a Lemon Blueberry Tart take to cook?
The filling itself only needs 17 to 19 minutes in the oven. You’ll know it’s done when the center no longer jiggles when you tap the pan lightly. The top might still look a little sticky, and that’s normal.
Does a fruit tart need to be refrigerated?
Absolutely. This summer fruit tart has dairy and eggs in the filling, so it needs to stay cold. Always store it covered in the refrigerator, and it’ll keep well for up to a week.

Notes
This tart is all about balance-bright lemon, rich creaminess, and pockets of sweet blueberry. Let it chill fully for the smoothest slices and best flavor. It’s the kind of dessert that feels fancy but comforting at the same time.
