Who Actually Has the Best Key Lime Pie?

We ate them all so you don't have to (but you should). The definitive ranking of Key West's most famous dessert.

The Great Key Lime Pie Debate

Ask ten people in Key West where to get the best key lime pie and you'll get ten different answers—delivered with the kind of passion usually reserved for politics and religion. This is a town where key lime pie isn't just a dessert; it's a cultural institution, a point of civic pride, and occasionally, a topic that can start an argument at a bar. Meringue or whipped cream? Graham cracker crust or pastry crust? Tart and tangy or sweet and creamy? Frozen on a stick or served on a plate? Everyone has an opinion, and everyone is convinced they're right.

We decided to settle the debate the only way possible: by eating them all. Over the course of several months (and a truly alarming number of calories), we sampled key lime pie from every bakery, restaurant, and roadside stand in Key West. Below are our findings—plus a little history, some tasting tips, and our honest rankings.

A Brief History of Key Lime Pie

Key lime pie has been the official state pie of Florida since 2006, but its origins are murky and hotly contested. The most popular story traces it back to the early 1900s and a woman known as "Aunt Sally," who reportedly created the recipe for William Curry, Florida's first self-made millionaire. But there's no definitive proof, and food historians have debated the claim for decades.

What we do know is that key limes (Citrus aurantiifolia) are native to Southeast Asia and were brought to the Florida Keys by Spanish explorers. They're smaller, seedier, and more aromatic than regular Persian limes—with a distinctive floral tartness that you can't replicate with supermarket limes. Before refrigeration was common in the Keys, cooks combined key lime juice with sweetened condensed milk (which didn't need refrigeration) and egg yolks to create a custard that set without baking. The graham cracker crust came later, as did the eternal meringue-vs-whipped-cream topping debate.

Today, authentic key lime pie is made with real key lime juice (not the bottled stuff), sweetened condensed milk, and egg yolks, baked briefly to set the filling. The color should be pale yellow—not green. If your slice is bright green, that's food coloring, and you should be suspicious of whatever else they're doing back there.

What Makes a Great Key Lime Pie?

After eating more key lime pie than any human probably should, we've identified the hallmarks of a truly excellent slice:

• The Filling: Should be smooth, creamy, and firmly set—not runny or gelatinous. The tartness should hit you first, followed by sweetness. You should taste real key lime, not artificial citrus flavor. The color should be naturally pale yellow.
• The Crust: A good graham cracker crust should be buttery, lightly sweet, and hold together when you cut a slice—not crumble into a pile of dust. Some places use a pastry crust, which can work beautifully if done right, but the classic graham cracker version is hard to beat.
• The Topping: This is where it gets personal. Meringue lovers argue that the light, toasted peaks complement the dense filling. Whipped cream fans say it lets the lime flavor shine. We love both, but we'll say this: a great meringue takes skill, while mediocre whipped cream is still acceptable. A bad meringue (weepy, flat, or overly sweet) can ruin an otherwise perfect pie.
• The Balance: The best key lime pies achieve a harmonious balance between tart and sweet, creamy and light. You should want another bite after every bite. If it's cloyingly sweet or so tart it makes you pucker, the balance is off.

Our Rankings

Here's our honest ranking of Key West's best key lime pies, from top to bottom. We'll probably get angry emails about this, but we stand by our taste buds.

1. Blue Heaven — The Meringue Mountain

Blue Heaven serves what might be the most photogenic key lime pie in existence. Their signature mile-high meringue topping is a towering, golden-tipped cloud that practically dares you to take a photo before diving in. But this isn't just Instagram bait—the pie underneath is genuinely excellent. The filling is perfectly tart with a silky-smooth texture, and the graham cracker crust is buttery and well-structured. The meringue is light and marshmallowy without being too sweet, and it's toasted to perfection. It's a showstopper, and for our money, it's the best overall key lime pie in Key West.

2. Kermit's Key West Key Lime Shoppe — The Classic

Kermit's has been doing one thing and doing it exceptionally well for years. Their traditional key lime pie is dependable, delicious, and exactly what you picture when someone says "key lime pie." But the real game-changer here is their chocolate-dipped frozen key lime pie on a stick. Imagine a creamy, tart key lime filling coated in dark chocolate and served frozen like a popsicle. On a sweltering Key West afternoon, there is genuinely nothing better. Kermit's also sells whole pies shipped nationwide if you want to bring the taste of Key West home.

3. Santiago's Bodega — The Sleeper Hit

Santiago's Bodega is known primarily as a tapas restaurant, but their key lime pie is a revelation that flies under most tourists' radar. The filling is incredibly creamy and rich, with a pronounced key lime flavor that's tart without being aggressive. Their crust is especially noteworthy—buttery, crunchy, and perfectly proportioned. If you're already eating dinner here (and you should—their tapas are fantastic), do not skip dessert.

4. Southernmost Beach Cafe — Best Setting

Is the key lime pie at Southernmost Beach Cafe the absolute best on the island? Maybe not by a hair. But eating it while sitting on the beach with your toes in the sand, watching the waves roll in? That context elevates it to something special. Their version is classic and well-executed, with a smooth filling and whipped cream topping. The setting makes it unforgettable.

5. Old Town Bakery — The Local's Choice

Tucked away on Eaton Street in a charming white clapboard building with green shutters, Old Town Bakery is where the locals go when they want key lime pie without the tourist markup. Their version is understated and honest—a perfectly tangy filling with real key lime juice, a buttery graham cracker crust that holds together beautifully, and just the right amount of whipped cream on top. No gimmicks, no mile-high meringue theatrics—just a really well-made pie. They also bake some of the best pastries, breads, and breakfast sandwiches on the island, so come early and make a morning of it.

6. The Key West Key Lime Pie Co. — The Award Winner

These guys have won multiple awards at food competitions, and their filling is notably rich and creamy—almost like a key lime cheesecake. If you prefer your key lime pie on the sweeter, denser side, this is your spot. They also offer creative variations like key lime pie with a pretzel crust and key lime pie ice cream.
