Storage and Make-Ahead Tips

This no-bake lasagna is perfect for prepping ahead of time. In fact, chilling it overnight enhances the flavor and helps the layers set for clean slicing.

Fridge: Store covered in the refrigerator for up to 4 days.
Freezer: Not recommended — whipped topping and pudding don’t freeze well and may separate when thawed.
Make-ahead: Prepare the entire dessert up to 2 days in advance. Garnish just before serving to keep the toppings fresh and crisp.

This dessert is ideal for holiday prep — just make it, chill it, and serve when ready.
