Let’s get started—your new favorite dessert awaits!
Ingredients
Key lime pie is all about balance—tangy, sweet, and creamy all at once. The secret? Using the right ingredients to nail that signature flavor and texture. Fresh key lime juice is non-negotiable for its bright, zesty kick, but regular limes can step in if needed. Every component plays a role, from the buttery graham cracker crust to the creamy filling that sets just right. Here’s what you’ll need:
For the crust:
- 1 ½ cups graham cracker crumbs (store-bought or DIY)
- 6 tbsp unsalted butter, melted (salted works, but adjust additional salt)
- ¼ cup granulated sugar (optional, but adds sweetness)
For the filling:
- 4 large egg yolks (save the whites for another recipe!)
- 1 can (14 oz) sweetened condensed milk (don’t swap—it’s essential for creaminess)
- ½ cup freshly squeezed key lime juice (use regular limes if key limes are unavailable)
- 1 tbsp key lime zest (adds an extra punch of flavor)
For garnish (optional but recommended):
- Whipped cream (homemade or store-bought)
- Extra lime zest or slices (for that professional touch)
Pro tips:
- Use fresh key limes—their juice is less bitter than bottled.
- For a sturdier crust, add an extra tablespoon of butter.
- Don’t skip the zest—it amplifies the lime flavor tenfold.
How to Make the Best Key Lime Pie Instructions
- Preheat your oven to 350°F (175°C)—ensuring it’s properly heated is vital for even baking. If you skip this step, the pie mightn’t set correctly.
- Prepare the graham cracker crust: Combine 1 ½ cups crushed graham crackers, ⅓ cup melted butter, and ¼ cup sugar in a bowl. Press the mixture firmly into a 9-inch pie dish, covering the bottom and sides evenly. Bake for 8 minutes, then let it cool completely.
*Pro Tip:* Use a flat-bottomed cup to press the crust—it creates a smooth, even layer.
– Make the filling: In a large bowl, whisk together 4 egg yolks and 1 can (14 oz) of sweetened condensed milk until smooth. Gradually add ½ cup fresh key lime juice and 1 tablespoon lime zest, mixing gently until fully combined.
*Watch-Out:* Overmixing can cause the filling to become too dense—stir just until smooth.
– Assemble the pie: Pour the filling into the cooled crust, spreading it evenly with a spatula. Tap the pie dish lightly on the counter to remove any air bubbles.
*Visual Cue:* The filling should be smooth and jiggle slightly when you move the dish.
– Bake for 15 minutes: Place the pie in the oven and bake until the filling is set but still slightly wobbly in the center.
*Flexibility:* If your oven runs hot, check at 12 minutes to avoid overbaking.
– Cool and chill: Let the pie cool to room temperature, then refrigerate for at least 4 hours or overnight. This step is pivotal—it allows the filling to firm up completely.
*Time-Saving Trick:* If you’re short on time, place the pie in the freezer for 1-2 hours instead.
– Serve and enjoy: Slice the pie and garnish with whipped cream and lime zest for a fresh, tangy finish.
*Pro Tip:* Use a sharp knife dipped in hot water for clean cuts.

Chef Tips
Although making Key Lime Pie seems straightforward, I’ve learned a few tricks over the years to guarantee it turns out perfectly every time.
Use fresh lime juice—never bottled—for the brightest flavor.
Chill the crust before filling to prevent sogginess.
Don’t overbake; the filling should jiggle slightly when shaken.
Let it cool completely before slicing.
A dollop of whipped cream balances the tartness beautifully.
Trust me, these small steps make all the difference.
