Ingredients

• Sweetened condensed milk. Sweetened condensed milk is your secret ingredient in this recipe.It works double-duty in providing the perfect amount of sweetness and helps the pie set.

• Key lime juice. Key lime juice is a must in this recipe, and luckily it’s found at most supermarkets.If you can’t find it, try subbing equal parts lime and lemon juice.

• Sour cream. Adding sour cream to a sweet pie sounds strange, I know. But it helps make an ultra-creamy pie filling.Don’t worry, it won’t taste anything like sour cream!

• Lime zest. Use any limes you have on hand.Adding lime zest takes those citrusy, tropical flavors over the top.

How to Make Key Lime Pie

You don’t have to be an expert in the kitchen to whip up this fantastic Key lime pie.Follow these simple steps to create the perfect sweet and tart dessert everyone will love.

1. Prepare. Preheat the oven to 350 degrees Fahrenheit.

2. Mix the Key lime filling. In a medium mixing bowl, combine the sweetened condensed milk, sour cream, Key lime juice, and lime zest.

Stir it until combined, and pour it into a graham cracker crust.

3. Bake. Place the pie in the oven, and bake it until the tiny bubbles on the surface burst, around 5 to 8 minutes.

The filling will be a little wobbly when you remove it from the oven.

4. Cool. Allow the pie to come to room temperature on a wire rack, then transfer it to the fridge for one hour.

5. Garnish. Before serving, garnish it with whipped cream and lime zest, and dig in!

How to Tell When Key Lime Pie is Done

One of the biggest mistakes in making Key lime pie is telling when it’s perfectly cooked.Unlike other baked treats, it doesn’t have an obvious tell when it’s set.

If you closely monitor it while baking, you can determine when it’s ready to take out of the oven.Here are a few tricks to tell when it’s ready.

1. Check the bubbles on the surface. When you pour the filling into the pie pan, it will create tiny little bubbles.As hot air escapes as it cooks, those bubbles on the surface will pop, letting you know it’s done.

2. Give it the jiggle test. A perfectly set pie has a bit of a wiggle in the center.After 5 minutes, give it a wiggle.A perfectly set pie has firm edges with some wobble in the middle.

Tips for the Best Key Lime Pie

Here are a few quick tricks and tips to make your key lime pie the talk of the potluck!

• Take it easy on the lime zest. Adding lime zest to the filling adds so much flavor, but it can quickly turn bitter.When adding lime zest to this recipe, less is more.

• Give your pie plenty of time to cool. Placing your pie in the fridge for an hour to set is the bare minimum.For a perfectly set pie, leave it in the fridge to set overnight.

• Don’t overbake! There’s nothing worse than when the top of that pie starts to brown.Key lime pie doesn’t take very long to cook in the oven. Hovering in front of the oven door is okay.

• Can’t find Key lime juice? There’s an easy substitute if you don’t want to hunt down Key lime juice.Mixing equal parts lemon and lime juice will provide that patented citrusy kick from Key limes.

• Make your crust. Store-bought graham cracker crusts are quick and easy, but nothing beats homemade! You have your crust essentials with butter, graham crackers, and brown sugar!

Make Ahead and Freezing Tips

You can get ahead of the game by preparing the pie the day before and placing it in the fridge.Insert toothpicks before covering the pie with plastic wrap to prevent sticking. A baked pie stays fresh in the fridge for 3 to 4 days.

Did you know you can also freeze Key lime pie? The best way to freeze it is to cover the top with parchment paper and then wrap it with aluminum foil.
