Strawberry Preserves: If you don’t have preserves, you could substitute strawberry jam. However, because preserves are made with whole or large pieces of fruit, the texture of the dessert may be a bit different.

Strawberries: I prefer fresh strawberries, but you could use frozen strawberries that have been thawed.

Can I Make Easy Strawberry Napoleon Ahead of Time?
Yes. Strawberry Napoleon Dessert can be prepped ahead of time for convenience and to save time. The puff pastry layers can be made in advance and frozen for later use. The cream cheese mixture can also be prepared ahead of time and stored in the refrigerator for up to 3-4 days. When ready to assemble the dessert, thaw the puff pastry layers and use the cream cheese filling. Fresh strawberries can be prepared in advance, but it’s best to add them just before serving to prevent sogginess.
