Classic Key Lime Pie

Key lime pie is the dessert that instantly makes me feel like I am on vacation, even when I am very much standing in my Kansas City kitchen with a pile of laundry behind me. That cool, tangy, creamy filling with the buttery graham crust is pure sunshine, and it is so much easier to make than people think.

I bring this to summer cookouts and it is always the first thing gone. There is something about that bright lime flavor against the sweet creamy base that just makes people close their eyes for a second. It is a showstopper that takes almost no effort.

Fresh juice is everything

The flavor of this pie lives and dies by the lime juice, so please use fresh. If you can find actual key limes, wonderful, but they are tiny and fussy to juice, so regular Persian limes work beautifully too and nobody will know the difference. A little zest in the filling adds even more of that fragrant lime punch.

A handheld citrus juicer makes quick work of all those limes, and a fine zester gives you that pretty zest without any bitter pith.

Let it chill, truly

I know the hardest part is waiting, but this pie needs at least three hours in the fridge to set up properly. A well-chilled pie slices into clean, gorgeous wedges, while a warm one will slump. I usually make it the night before so it is ready to go and one less thing to fuss over on the day.

Bake it in a sturdy glass pie dish so you can see those pretty layers, then crown it with fresh whipped cream and a few lime slices right before serving.

Ingredients Method Notes

Ingredients

  

For the crust

• 1 1/2 cups graham cracker crumbs
• 1/3 cup butter melted
• 3 tablespoons granulated sugar

For the filling

• 3 cups sweetened condensed milk about 2 cans
• 4 large egg yolks
• 3/4 cup key lime juice
• 1 tablespoon lime zest

For the topping

• 1 cup heavy whipping cream
• 2 tablespoons powdered sugar

Method

 

1. Preheat the oven to 350 degrees F. Mix the graham cracker crumbs, melted butter, and sugar, then press into a 9-inch pie dish.
2. Bake the crust for 8 minutes, then set aside to cool slightly.
3. In a bowl, whisk the sweetened condensed milk, egg yolks, key lime juice, and zest until smooth.
4. Pour the filling into the crust and bake for 15 minutes until just set.
5. Cool completely, then chill in the fridge for at least 3 hours.
6. Whip the heavy cream with the powdered sugar to soft peaks and spread or pipe over the chilled pie before serving.

Notes

Chill the pie for at least 3 hours so it sets up firm and slices cleanly. Regular limes work beautifully if you cannot find key limes.

Bring on the sunshine

Make this once and it will become your warm-weather signature. Tangy, creamy, cool, and just sweet enough. I hope it brings a little vacation feeling to your table too.

So glad you are here.
