In a large bowl, beat the softened cream cheese, icing sugar, lemon juice and vanilla until smooth.
Blend half of the roasted strawberries and mix the purée into the cheesecake mixture.
Whisk the cold whipping cream (with an electric whisk or by hand), until soft peaks are reached.
Gently fold the whipped cream into the strawberry cheesecake mixture. Fold in a couple tablespoons of the whipped cream to loosen the cheesecake before adding the remaining whipped cream.
Place the remaining half of the roasted strawberries over the crust, making sure to leave a 2 cm gap from the edge.
Add the cheesecake mixture gently on top of the roasted strawberries and level off the surface.
Place in the fridge to cool and set (allow to set for at least 30 minutes before adding the jelly layer).
