This is a recipe given to me by a world-class chef, who claimed it is "the easiest key lime pie recipe in the world." And it's true!

It's a nicely tart dessert, without all that meringue and sugar. And it's the kind of pie that people love, which makes it fun to bring to parties. ("Oh, this? Just a secret family recipe smuggled out of Europe during WWII that requires 15 days of hard toil, a full moon, and a dash of fairy dust to set correctly… but you're worth it.")

  1. I make this recipe semi-regularly and love it! I recommend buying a lime or two as well, and using a cheese grater to zest the lime. Mix the zest in with the filling. It adds a bit of flavor and if you're into green color, that too…

  2. "177 degrees Celsius for my Canadian friends out there"

    Actually, our ovens are mostly made in the US, so most of us have Fahrenheit as well. However, I'm sure the European crowd will thank you 🙂

  3. Pretty sure this is the recipe my mom uses and it's super yum all the time. Bonus points for fresh whipped cream on top.

  4. So, if anyone wants to try this with fresh key limes as opposed to the bottled juice (nothing wrong with the bottled juice though), I have two tips.

    1) Zest the key limes *before* you juice them. Put some of the zest in the custard, sprinkle some on the finished pie (I top it with stiff whipped cream)

    2) To juice the limes, cut them in half and squeeze them in a pair of kitchen tongs (jam them in near the hinge for maximum physics). Attempting to use a juicer will lead to frustration and heartbreak.

  5. This sounds so yummy!
    I'm across the pond and have no access to key limes. What do they taste like, compared to usual limes or lemons? Do you think a mix of the two could substitute it?
    Also, what exactly is a graham crackers crust? The kind you'd make crushing cookies and mixing them with butter?
    Thanks!

  6. It does sound super easy. I'm in the UK and was also wondering about the limes tho I guess just regular lime juice would work too. Also if I could get a gluten free pie crust that would be great!

    • You can totally make a graham cracker crust with gluten-free cookies. Just crush them up, mix them with a little butter and sugar (slightly drier than you would use for making a sand castle), mush the mix into a pie plate, and bake it for about 10-15 minutes.

      I would not use regular (persian) lime juice however. Key limes are far sweeter, less sour, and far less bitter. I'd use lemons before I'd use regular limes.
