This simple Thanksgiving dessert is the kind of clever shortcut bake that feels almost too easy for the payoff. Using frozen puff pastry sheets straight from the freezer creates a flaky, buttery base with minimal prep, while two additional ingredients turn it into a warm, sweet casserole-style treat that fits right in on a holiday table. It has the spirit of rustic fruit pastries and cobbler-inspired bakes, but with a streamlined method that works especially well when oven space and time are limited.

Serve this dessert warm with vanilla ice cream, lightly sweetened whipped cream, or a spoonful of crème fraîche to balance the sweetness. It also pairs nicely with coffee after dinner, hot cider in the afternoon, or a small drizzle of caramel sauce if you want it to feel a little more holiday-special. For a Thanksgiving spread, it sits beautifully beside roasted nuts, fresh pears, or a platter of sharp cheeses for contrast.

Ingredients

1 package solid frozen unthawed puff pastry sheets, about 2 sheets

1 can apple pie filling, about 21 ounces
1/4 cup cinnamon sugar

Directions

1. Preheat the oven to 375°F and lightly grease an oven-safe ceramic casserole dish.

2. Place the solid frozen unthawed puff pastry sheets flat in the casserole dish, overlapping slightly if needed to fit.

3. Spoon the apple pie filling evenly over the pastry, spreading the fruit so it covers most of the surface.

4. Sprinkle the cinnamon sugar evenly over the top.

5. Bake for 35 to 45 minutes, until the pastry is puffed and deeply golden and the filling is bubbling around the edges.

6. Let the dessert rest for 10 minutes before serving so the filling settles slightly and the pastry stays crisp on top.

Variations & Tips

Pear Version: Swap the apple pie filling for pear pie filling if you can find it, or use canned sliced pears tossed with a little sugar and cinnamon for a softer, more delicate holiday flavor.

Extra Crunch: A handful of chopped pecans or walnuts scattered over the filling before baking adds texture and makes the dessert feel especially appropriate for Thanksgiving.

Crisper Pastry Tip: If your casserole dish is deep, try arranging the puff pastry so some edges sit slightly above the filling. Those exposed corners will bake up especially crisp and flaky.

Serving Tip: This dessert is best served warm the day it is baked, but leftovers can be reheated in a 300°F oven for a few minutes to refresh the pastry better than a microwave will.
