Ingredients List for the Easy Key Lime Pie

These ingredients combine the perfect balance of sweet and tart elements to create that authentic key lime flavor. The traditional graham cracker crust provides the ideal crunchy foundation for the creamy filling.

• 1/3 cup butter (melted)
• 1/4 cup sugar
• 1 1/4 cup graham cracker crumbs
• 4 egg yolks
• 6 key limes (for zesting and juicing)
• 14 ounces sweetened condensed milk
• Nellie & Joe’s Famous Key West Lime Juice (if needed)
• Whipped topping to garnish (optional)

Pro Tips

Achieving the perfect Easy Key Lime Pie comes down to mastering a few critical techniques. First, when preparing your crust, use the bottom of a measuring cup to firmly press the graham cracker mixture into your pie plate. This creates an even, compact base that won’t crumble when sliced. The difference between a good crust and a great one is in how firmly it’s packed.

Second, pay close attention to your egg yolks. Whip them until they’re noticeably lighter in color and thicker in consistency—this creates the proper structure for your filling. Rushing this step results in a less stable pie that might not set properly.

Finally, authentic key lime flavor comes from using real key limes whenever possible. These small, aromatic limes deliver a distinctive tartness regular limes can’t match. If you can’t find fresh key limes, Nellie & Joe’s bottled juice is the next best option, offering significantly better flavor than regular lime juice. Always add the zest as well—it contains essential oils that amplify the citrus punch in your finished pie.

Instructions

Step 1: Make the Crust

Combine melted butter and sugar in a medium bowl. Stir in crushed graham crackers.

Spread evenly into a 9-inch pie plate and press onto bottom and sides to form an even crust (use the bottom of a measuring cup to press firmly).

Chill for 1 hour until firm OR bake at 375°F for 5 minutes and allow to cool before filling.

Step 2: Prepare the Filling

Preheat oven to 350°F.

Zest key limes until you have 2 teaspoons of zest, then juice them into a ½ cup measuring cup.

If the ½ cup isn’t full, add bottled key lime juice to fill completely.

Whisk egg yolks until thick and light yellow using a stand or electric mixer.

Slowly add sweetened condensed milk on low speed while mixing.

Gradually add key lime juice and zest, mixing on low just until blended.

Step 3: Bake the Pie

Pour the mixture into the prepared pie shell.

Bake for 15 minutes.

Remove and let cool to room temperature, then refrigerate until ready to serve.

Step 4: Serve

Garnish with whipped topping, lime slices, and a little lime zest if desired.

Variations

The classic Easy Key Lime Pie is perfect as is, but these popular variations offer delightful twists on the original:

For a tropical spin, try a Coconut Key Lime Pie. Simply add 1/2 cup toasted coconut to your graham cracker crust mixture and fold 1/4 cup coconut cream into your filling. Top with toasted coconut flakes for an island-inspired dessert that pairs beautifully with summer gatherings.

Those seeking a gluten-free option can substitute the graham crackers with gluten-free cookies or a nut-based crust. Combine 1 1/2 cups of finely chopped nuts (almonds or pecans work beautifully) with 3 tablespoons of sugar and your melted butter for a naturally gluten-free foundation that adds wonderful texture.

For a special occasion, consider a meringue-topped key lime pie. Use the leftover egg whites to create a fluffy meringue topping. Beat them with 1/4 cup sugar until stiff peaks form, spread over your cooled pie, and briefly torch or broil until golden for an impressive presentation.

Storage and Serving

Your Easy Key Lime Pie will keep beautifully in the refrigerator for up to 3 days when covered with plastic wrap or stored in an airtight container. The flavors actually develop and meld together after the first day, making this an ideal make-ahead dessert. For longer storage, you can freeze the pie for up to one month—simply wrap it tightly in plastic wrap followed by aluminum foil to prevent freezer burn.

When serving, allow a frozen pie to thaw overnight in the refrigerator for the best texture. For the ultimate presentation, slice your chilled pie with a knife dipped in hot water and wiped clean between cuts for picture-perfect slices. Serve alongside a dollop of freshly whipped cream and a small wedge of lime for an elegant touch.

For a delightful dessert pairing, serve your key lime pie with a cup of strong coffee or espresso—the bitterness beautifully complements the sweet-tart flavor profile of the pie. For special occasions, a glass of dessert wine like Moscato d’Asti makes a sublime accompaniment.

FAQs

Can I use regular limes instead of key limes?
Yes, you can substitute regular limes, though the flavor will be slightly different. Key limes have a more intense, aromatic quality. If using regular limes, reduce the amount slightly as they tend to be less tart.

Why did my filling not set properly?
The most common reason is underbaking or not chilling long enough. Make sure to bake for the full 15 minutes and allow at least 4 hours of refrigeration time. Also, ensure you’re using the correct amount of condensed milk and lime juice.

Can I make this Easy Key Lime Pie without eggs?
Traditional key lime pie requires egg yolks for proper setting and texture. For an egg-free version, you’d need to use cream cheese (8 oz) combined with the condensed milk and add 1 tablespoon of cornstarch to help it set.

How do I know when the pie is done baking?
The pie is done when it’s mostly set but still has a slight jiggle in the center—similar to how a cheesecake looks when finished. It will firm up completely during cooling and refrigeration.

Is it necessary to bake this pie?
Yes, baking is essential for food safety as it cooks the egg yolks. Some no-bake versions exist, but they typically use different ingredients like cream cheese instead of the traditional egg-based filling.
