Why You’ll Love Strawberry Mousse Tartlets Recipe

I love how these tartlets combine a buttery, flaky crust with a smooth and airy strawberry mousse filling. The fresh strawberries provide natural flavor and color, while the mascarpone adds a rich creaminess that makes every bite irresistible. I also appreciate that these mini desserts can be made ahead of time, making them ideal for parties, holidays, and special occasions. Their individual size makes serving easy and elegant.

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

pie dough, store-bought or pre-made, enough for 2 pie crusts

2 Cups strawberries, fresh, chopped

1 Tablespoon lemon juice, fresh is best

1 Tablespoon gelatin, unflavored

8 Ounces mascarpone cheese

½ Cup granulated sugar, divided plus 1 tablespoon

2 Cups whipping cream, divided

1 Teaspoon vanilla extract, divided and 1/2 teaspoon

Optional Garnishes:

strawberries, fresh

mint sprigs, fresh

Directions

I preheat the oven to 400°F.
On a lightly floured surface, I roll out the pie dough to about 1/8-inch thickness.
I cut out 5-inch circles and gently fit them into the tart or mini pie pans.
I reroll any scraps and continue cutting until all the dough is used.
I place the tart pans on a baking sheet, line each crust with parchment paper, and fill them with pie weights.
I bake the crusts for 12 to 15 minutes.
I carefully remove the pie weights and parchment paper, then bake for another 4 to 5 minutes until golden brown.
I allow the crusts to cool for 5 minutes in the pans before transferring them to a cooling rack to cool completely.
While the crusts cool, I blend the chopped strawberries and lemon juice until mostly smooth.
I transfer the strawberry mixture to a medium saucepan and stir in the gelatin.
I heat the mixture over medium-high heat for 4 to 5 minutes, stirring continuously until the gelatin dissolves completely.
I remove the mixture from the heat and allow it to cool to room temperature, about 30 minutes.
Once cooled, I fold in the mascarpone cheese and 1/4 cup of the granulated sugar until smooth.
In a stand mixer, I whip 1½ cups of whipping cream with 1 teaspoon vanilla extract until soft peaks form.
I gradually add another 1/4 cup granulated sugar and continue whipping until stiff peaks form.
I gently fold the whipped cream into the strawberry mixture in three additions.
I spoon the mousse mixture evenly into the cooled tart shells.
I refrigerate the tartlets for 2 to 3 hours until fully set.
Before serving, I whip the remaining 1/2 cup whipping cream with the remaining 1/2 teaspoon vanilla extract.
I slowly add the remaining tablespoon of sugar and whip until peaks form.
I top each tartlet with whipped cream and garnish with fresh strawberries and mint if desired.

Variations

I sometimes use raspberries or mixed berries instead of strawberries for a different flavor profile. When I want a more citrus-forward dessert, I add extra lemon zest to the mousse mixture. For added texture, I like sprinkling crushed graham crackers or shortbread cookie crumbs over the whipped cream topping. Chocolate lovers can drizzle melted white chocolate over the finished tartlets for an extra indulgent touch.

Storage/Reheating

I store these tartlets covered in the refrigerator for up to 3 days. Because the mousse contains whipped cream and mascarpone, I keep them chilled until serving time. If I need to make them ahead, I prepare the tartlets a day in advance and add the whipped cream garnish just before serving for the freshest presentation. Freezing is possible, although the texture of the mousse may change slightly after thawing.

FAQs

Can I use frozen strawberries?

I can use frozen strawberries, but I thaw and drain them first to remove excess moisture before blending.

Can I use store-bought tart shells?

I often use pre-made tart shells when I want to save time, and they work wonderfully in this recipe.

What does mascarpone cheese add to the mousse?

I find that mascarpone creates a rich, silky texture and helps stabilize the mousse.

Can I make these tartlets ahead of time?

I like making them a day in advance and keeping them refrigerated until serving.

How do I know when the mousse is set?

I check that the filling feels firm and holds its shape when lightly touched.

Can I substitute cream cheese for mascarpone?

I can use cream cheese, although the flavor will be tangier and the texture slightly denser.

Why is gelatin used in the recipe?

I use gelatin to help the mousse set properly and maintain its light, airy structure.

Can I make one large tart instead of mini tartlets?

I can use a larger tart pan and adjust the filling amount accordingly for a full-sized dessert.

What toppings work best with these tartlets?

I enjoy topping them with fresh strawberries, whipped cream, mint leaves, or even a drizzle of white chocolate.

How long can the tartlets stay out at room temperature?

I try not to leave them out for more than 2 hours because the mousse filling is dairy-based.

Conclusion

I love serving these Strawberry Mousse Tartlets whenever I want a dessert that looks impressive yet feels surprisingly simple to make. The combination of flaky crust, creamy strawberry mousse, and fresh toppings creates a refreshing treat that is perfect for celebrations, afternoon gatherings, or anytime I’m craving something light and fruity. Their beautiful presentation and delicious flavor make them a dessert I return to again and again.
