Best Key Lime Pie

The Best Key Lime Pie recipe EVER! And so darn easy too! You won’t be able to stop at just one slice!

The Best Key Lime Pie recipe EVER! And so darn easy too! You won't be able to stop at just one slice!

I’m, admittedly, not much of a pie person. But this, this Key Lime Pie, has changed my life.

So, confession time. I didn’t use key limes for this pie. I used regular ole limes that you can find anywhere. I meant to use key limes but after three stores I gave up. Ain’t nobody got time for that.

So here’s the skinny on the key lime pie sitch, you don’t have to use key limes. They may, may make the pie a teensy bit better but goodness gracious I was so happy not to have squeeze 20+ key limes for this pie. It was a blessing in disguise fo sho!

After all of that, Happy Pi Day! With an electrical engineering degree you can bet I’ve had my fill of pi. But never, NEVER will I have my fill of this pie.

So this “key” lime pie recipe is crazy easy. And I mean cray-zee.  So easy, you may find yourself making one a week, like I plan to, for the rest of my life.

The pie starts with a graham cracker crust. I am terrible at crusts but gosh darnit, a homemade graham cracker crust tastes WAY better than a store bought one and it’s pretty simple to make. Just some graham cracker crumbs, sugar and butter will do it.

Now let’s get to the filling. It’s a whole lotta lime juice, lime zest, sour cream and a couple cans of sweetened condensed milk (a.k.a. nectar of the gods). You just whisk it all together, pour it into your pie shell, bake for 10 minutes and voila – you’ve got a key lime pie that will blow your family and friends away.

The truth is, I’m not much of a decorator when it comes to pies and cakes. I’m all about simple, easy, get-it-in-my-mouth-as-quick-as-possible. You too? Good. Then you’ll like my no-nonsense whipped cream topping.

If you are in a hurry, and I mean, a BIG HURRY, I would perhaps allow you to use a store bought pie crust and a can of whipped cream.  This pie would still be heavenly. No doubt.

  1. Oh my gosh the thought of squeezing all those key limes! No thank you. Love using lime juice or key lime juice instead. Thanks for being nerdy with me today and posting pie!! :) xo

  2. Key limes can be a pain because there’s so darn many of them, and I’ve even used lemon before and called it “key lemon pie” haha. The funny part was, it didn’t taste much different! It’s a signature pie for me, and love how much lime juice you used and the sour cream sounds like a great addition. Beautiful pie, Trish!

  3. “…not much of a pie person.” Dude. My ears are bleeding. Lol. What I find funny about that is, I’ve made a few of your pies and they’re awesome. So you crazy, girl. I will for sure, make this one, too. I want all the pie!!!

  5. No no no no no! You cannot call this KEY lime pie, without TRUE, genuine, fresh squeezed Key Lime Juice, from fresh, genuine, KEY LIMES. What you have here is a wonderful Lime Pie, but it is NOT the same. Deep breaths……by the way, I LOVE all your recipes and your blog. In fact I am going out to get some key limes now, and try this recipe. (By the way, I had a Key Lime Pie recipe published by the Miami Herald waaaay back in the ’80’s!

  6. Key lime pies are the best, and this one has the greatest filling! I love melting white chocolate into my graham cracker crusts when I do key lime to play against the tang. This one looks pretty darn perfect!

  7. I adjusted this recipet to have a gluten-free crust for my daughter. It was great. She lived in Key West for 10 years so she was happy to get the recipe.

  8. key lime is one of my all time favorites, and without a regular pastry crust, one of the few I can actually make – this looks incredible Trish!

  9. Oh how delicious!! I love a key lime pie, especially as it gets warmer. It says spring and summer to me and I am definitely ready for spring and summer! :) pinning, stumbling and yumming

  10. Happy belated Pi day! This pie looks delicious! (I don’t even know what key limes look like, so probably you would have told me to get key limes and I would have just ignored that and come back with a bunch of regular limes;)

  12. I make a very similar pie (I happen to have a key lime tree in my backyard) only it has an eight ouce block of cream cheese that when chilled makes the pie firm. Also, I use ginger snaps for the crust and sometimes add coconut or pretzels. Delish!

  13. This looks too easy not to try! I will have to make this for sure!

    i made this for tomorrow’s Easter celebration, and I am totally calling a key lime pie. I like the rubber spatula…the filling is do delicious!

  20. Man, every time I see pictures of Key lime pie my mouth waters

  21. Melissa says:

    How far in advance can I make this? I was considering making it Wednesday for a dinner on Saturday, will it keep okay?

  22. I love a traditional key lime pie–and I really like the extra zest you added on top! If you don’t want to squeeze 80 billion key limes (and who does?), I use Nellie and Joe’s Key Lime Juice. Just open and measure, and gives that extra tart, tangy key lime punch to this pie. It’s even what I used at the restaurants I worked in, so it’s not even cheating. =)

  23. Hi…
    I am from Croatia and would like to make this pie for my birthday on saturday. Could you tell me how much condensed milk I need in milliliters? Thank you for your answer

  24. Just tried this pie – OMG – Soooo goood!!! Exactly as you promised – easy & delicious. Can’t wait to make another one. :)

  25. Hi ! Thank you very much this recipe !!! Looks delicious ! I had just one question before making the pie : how can the filling be so ferm without eggs ?
    Thank you !
    Greetings from France,
    Héléna

  26. I grew up on key lime pies in Miami and my question is when did it become acceptable to replace meringue with whipped cream? A real key lime pie has meringue and isn’t green

  27. I was torn between recipes that call for eggs and those that don’t, so I compromised by using this recipe and adding one egg and only using 1/4 cup of sour cream. I don’t know if it made much of a difference but it was the best key lime pie ever (maybe the best pie ever)! I used a granola crust and made coconut whipped cream to go on top.

  28. My husband was commenting that we don’t have dessert very often. I found this recipe on Pinterest and I had most of the ingredients at home and thought it sounded like an easy surprise. It was!! If I can do this anyone can. He loved it and had to share it with friends almost immediately after tasting it. Thanks for the recipe! We loved it!!!

  29. Melinda says:

    This recipe has descended itself from the heavens and I feel like I know what my purpose in life is after making this.

    I’ve made this about 3-4 times now and every time I make it I have a mini stroke from how good it is. I once made it with a ginger snap crust and…. omg I don’t even have words for it.

    Thank you for sharing this heavenly recipe :)

  30. Jessica says:

    Made this lastnight and it was so good. Everyone loved it and it’s all gone. Thanks for the recipe:)

  31. FYI you can by key lime juice in the supermarket. It is from Key West too. NO WAY would I squeeze all those key limes. I will follow the rest of the recipe except I’m going to use key lime juice from the bottle. I’m going to make it for my husband’s birthday Wednesday. Thanks for posting. Key like pie is my all time favorite and my husband hs fallen for it as well. :)

  32. Made this today for my husband for his birthday. Absolutely delicious! Moved recently and could not find a pie pan…….used a Spring Form pan and turned out perfectly with a nice looking edge :)
    Thanks for the recipe!

  33. What do you refer to in your recipe as half and half? We are not accustomed with that term here in South Africa.

  34. Hi , I’m from Argentina and I want to try your recipe, but here we don’t use Oz so I ‘m a little confused 2 14 oz is 2lb oz ? Thank you !!!

  35. this truly is the best key lime pie ever! we have made it multiple times after trying it this winter, thank you!
