Make the strawberry layer: In a bowl, toss the sliced strawberries with sugar and lemon juice. Let them sit for 10 minutes until they get juicy.
Prepare the crust: Mix graham crumbs, melted butter, sugar, and a pinch of salt.
The mixture should look like wet sand and hold together when pressed.
Whip the cream: In a cold bowl, beat the heavy cream to stiff peaks. Set aside.
Mix the cheesecake base: In another bowl, beat softened cream cheese, powdered sugar, vanilla, and lemon zest until smooth and fluffy.
Fold together: Gently fold the whipped cream into the cream cheese mixture in two additions until no streaks remain.
Assemble the jars: Spoon 2–3 tablespoons of crust into each jar and press lightly. Add a layer of cheesecake filling, then a spoonful of strawberries and their juices.
Repeat layers if your jars are tall, finishing with strawberries.
Chill: Cover and refrigerate for at least 2 hours, or up to 24 hours, to set and let flavors meld.
Finish and serve: Top with extra berries, a sprinkle of crumbs, or a small swirl of whipped cream. Serve cold.
