• 1 tablespoon lemon zest finely grated
• 1 container (8 oz) frozen whipped topping fully thawed

Notes

Pro Tips:

• Chill the condensed milk before mixing to help the filling thicken faster.
• Use freshly squeezed lemon juice for the brightest flavor and best texture.
• Make sure the whipped topping is completely thawed before folding it into the filling.
• Whisk the lemon juice into the condensed milk gradually for an even consistency.
• Use a warm, dry knife and wipe it between cuts for clean slices.
• Keep the pie covered in the refrigerator to prevent it from absorbing other food odors.

Storage: Cover and refrigerate for up to 4 days. The crust is crispest during the first 2 days. Freeze tightly wrapped for up to 2 months and thaw in the refrigerator for approximately 30 minutes before slicing.

Variations: Use a chocolate cookie crust for a chocolate-lemon combination, add fresh berries for a blueberry lemon pie, spoon the filling into individual dessert jars, or freeze individual slices for refreshing lemon pie bites. You can also replace the whipped topping with 1 1/2 cups cold heavy cream whipped to stiff peaks.

Pro Tips

• Chill the condensed milk first, because a cold can helps the filling thicken faster.
• Squeeze the lemons fresh, since bottled juice can taste flat and may weaken the set.
• Thaw the whipped topping completely so it folds in without lumps.
• Add the lemon juice while whisking so the filling thickens evenly.
• Use a hot, dry knife and wipe it between cuts for clean slices.
• Keep the pie covered in the fridge so it does not absorb other food smells.

FAQs

Can I really make this in 15 minutes?
Yes, the hands-on work takes about 15 minutes with a store-bought crust. The chilling time is what firms it up, so plan ahead for the slicing.

Can I use real whipped cream?
Absolutely, whip 1 1/2 cups of cold heavy cream to stiff peaks and fold it in the same way. The pie tastes richer and may soften a little faster at room temperature.

How long does this pie keep?
Covered, it stays fresh for up to 4 days in the fridge. The crust is crispest within the first 2 days.

Can I freeze it?
Yes, freeze it wrapped tightly for up to 2 months. Let it sit in the fridge for 30 minutes before slicing. For another lemon bake, try my authentic southern lemon cake.

Why is my filling runny?
It usually needs more chilling time, or the lemon juice was measured a bit generously. Give it a full 4 hours and measure carefully next time.
