Classic Key Lime Pie Recipe with Italian Meringue

This Classic key lime pie recipe features a graham cracker crust, a creamy sweet-tart filling made with ordinary limes, and homemade Italian meringue on top. It’s so easy to make, but it looks and tastes amazing! 

I learned how to make this Classic Key Lime Pie recipe with Italian Meringue when I was a teen LOL. And it’s been one of my friends’ favorites.

Actually, I was honored when one of them {a special one} said that mine was the best one he had ever tried LOL. That was a great compliment since he is a huge fan of Lime pies LOL.

Anyway, I made this recipe after many years out of the baking mood and it turned out great {thankfully!}.

How to Make this Classic Key Lime Pie Recipe

This recipe is super easy to make. This time I didn’t make the crust, I just bought it and it was pretty good actually =D.

So, the whole recipe took me about 50 minutes or so to have it ready.

Ingredients:

Pie

• Sweetened condensed milk – to thicken and sweeten the filling.
• Egg yolks – this adds so much richness.
• Limes {Finely grated zest and juice} – I recommend fresh juice but bottled key lime juice works too.
• Extra lime zest for the decoration
• Pre-made Pie Crust – You can me this yourself but I preferred a pre-made one

Meringue

• Egg whites
• Sugar
• Water
• Icing sugar (powdered sugar)

Directions:

Preheat the oven to 180ºC (350ºF).

You can also make your own crust if you prefer by mixing graham cracker crumbs with melted butter, press the mixture into the bottom and sides of a 9-inch pie plate, and then bake it for a few minutes to firm up. For a full crust recipe, you can check out my apple cinnamon cheesecake recipe.

The Key Lime Filling

1. In a blender, mix the egg yolks and the condensed milk for 3 minutes then add the zest and mix for 3-5 more minutes.

The mixture will turn very thick and hot {fun chemical reactions}.

2. Pour the filling into the crust base then put it in the oven. Bake for 15-20 minutes or until it puffs up and becomes a bit golden.

3. Let it cool on a wire rack then chill for at least 6 hours or overnight {it’s even better but I couldn’t wait LOL}.

For the meringue Topping:

4. In a bowl of an electric mixer with the wire whisk attachment, place the egg white and whip it on medium-high speed. Make sure the bowl is dry and clean.

5. In a small pan, heat the water and the regular sugar to create caramel sauce. It will gradually become thicker. You will know when it’s ready when you take some of it with a skimmer and blow softly and you see bubbles going through the holes of the skimmer. =D. Turn off the heat.

6. When the egg white is at soft peaks, add the icing sugar and mix for 3 minutes and pour the hot caramel into the beating egg white very slow and steady.

7. After the sugar mixture is added, increase the speed to high and beat until the bowl is cool to the touch. It could take about 5-10 minutes. You can check out a more detailed recipe for Italian Meringue HERE.

8. Place the meringue on top of the pie quickly. Once the meringue sets up, it’s hard to work with it. If this ever happens, you just need to put it back into the mixer and whip until stiff peaks form again.

9. To decorate, I used the back of a tablespoon and pressed it against the meringue and pushed it up many times all over the meringue. It forms those cute peaks.

10. The final touch was extra lime zest spread all over the pie. You can also add some lime slices around the pie or decorate to taste.

Serve and enjoy!
