When it comes to desserts, I believe that it should taste like you spend three days in the kitchen without actually having to do it. Who is with me?! Because when you want dessert, you don’t want it to take all day!


This Strawberry Mousse Tart was made for those first beautiful days of spring,  studded with fresh juicy strawberries, garden fresh thyme, and fresh cream. Fresh, juicy strawberries are roasted with vanilla beans and thyme to utter perfection. The roasted strawberries are then turned into a beautifully creamy and fluffy strawberry mousse for a no-bake pie that was meant for sharing on a beautiful warm day.

How to Roast Strawberries

Roasted strawberries have a deep, delicious flavor – juicier, sweeter, and almost caramel-y. To make Vanilla and Thyme Roasted Strawberries:

  • Take 1 lb of fresh or frozen strawberries and remove the stems.
  • Slice into quarters and place on a rimmed baking sheet lined with a sit-pat mat.
  • Toss the strawberries with brown sugar, fresh thyme, and the seeds of a vanilla bean.
  • Roast in a preheated oven (at 375 degrees) for about 30 to 35 minutes.

How Your Kids Can Help You Bake

One of the best ways of getting kids interested in eating new foods is to have them help you in the kitchen! The more involved they are, the more likely they will want to try it and actually like it. Here are some great age appropriate ways to get your kids baking in the kitchen with you to make this roasted strawberry mousse tart:

  • Kids aged 1-3 can help you wash the strawberries, measure out ingredients, and help hold the mixer while you whip the cream.
  • Kids aged 4-6 can help you slice the strawberries, ready the strawberries to be roasted, help mix and roll the shortcrust pastry, help fold the pureed strawberries into the whipped cream, and help place the filling into the shortcrust pastry.
  • Kids aged 7-10+ can help you cut open the vanilla bean pod and scrape out the seeds, help roll out the shortcrust pastry, and puree the strawberries with the immersion blender.

*Please note that these recommendations are generalized, and to please use your personal discretion with your child’s skill level. And always, always supervise! Read more about how to have your children help you in the kitchen.

Roasted Strawberries:

  • 15 oz or 2 cups strawberries

To Make the Shortcrust Pastry:

  • Cool completely.

To Make Strawberry Mousse Filling:

  • When the roasted strawberries are cooled slightly, place them in a large bowl.
  • Puree the strawberries with an immersion blender until smooth.
  • Sprinkle 1 teaspoon of gelatin over the strawberries and allow to cool for 30 minutes.
  • Whip the heavy whipping cream to peaks.
  • Gently fold the whipped cream into the pureed strawberries.
  • When the tart crust is cool, place the strawberry mousse into the tart crust and smooth to create an even layer.
  • Chill for at least 2 hours before serving.
  • Enjoy!

  1. Roasting strawberries brings out even more sweetness! So good!

    1. Hi Dee, this recipe uses a standard pie plate, which are usually 9″ in diameter. Sometimes pie plates can be between 8″ and 10″, and this recipe would work just fine for those as well, just make sure you fit the crust to your pan.
