30 Minute Light Lemon Pie is a fresh lemon dessert made with cinnamon graham crackers, butter, sweetened condensed milk, eggs, lemon juice, and lemon zest.
It has a soft lemon filling, a crumb crust, and a chilled finish that makes it great for warm days, weekend dessert, or a make-ahead treat for guests.
This pie keeps things practical. You don’t need a long ingredient list, and the flavor comes mostly from fresh lemon juice and zest. The graham cracker crust adds a little cinnamon flavor without making the pie feel heavy.
Serve it after dinner, bring it to a potluck, or keep it in the fridge for a cold dessert that slices clean after it chills. A pie dish, food processor, mixing bowl, and measuring cups are the main tools you’ll use, so the setup stays manageable.

Tips and Tricks
Chill before slicing – Let the pie chill long enough before serving. This helps the filling set and makes cleaner slices. Use fresh lemons – Fresh lemon juice and zest give the pie a better citrus taste than bottled juice alone. Press the crust firmly – Use the bottom of a measuring cup to press the crumbs into the pie dish. This helps the crust hold together when sliced. Let the pie cool before chilling – Let the pie cool at room temperature before placing it in the refrigerator. This helps prevent extra moisture on top.Storing
Store in the Refrigerator – Cover the pie and store it in the refrigerator for up to 4 days. Freeze – Wrap the cooled pie tightly and freeze for up to 2 months. Thaw in the refrigerator before serving. Serve Chilled – This pie is best served cold, so keep it refrigerated until ready to slice.Nutrition
