Place cream cheese in a large bowl; beat with an electric mixer until smooth, 2 to 3 minutes. Add sugar; mix until combined, 1 to 2 minutes. Add eggs; blend for 1 to 2 minutes. Add lemon zest and juice; mix until incorporated. Pour mixture into cooled tart shell.

Bake in the preheated oven until filling has set, about 25 minutes. Chill thoroughly, at least 1 hour. Top with berries and garnish with mint.
