This is one of the easiest and quickest Key Lime pie recipes you’ll find anywhere. It uses canned key lime pie filling but is modified to create one of the most flavorful key lime pies you’ll ever eat. Adding key lime juice adds that tangy signature taste that Key Lime pie is famous for. Key lime pie is extremely popular in the South, especially in Florida. In other areas of country it appears to be more of specialty dessert served mostly in restaurants.
The first time I tried key lime pie was in a little restaurant in Key West after a long day walking around the village. I expected the pie to be rich and sugary, since it’s basically cheesecake. Instead, the tart citrus flavor hit me immediately and made my lips pucker and eyes close for a nanosecond. After a few more bites, I started to appreciate the balance of sweet and tangy flavors. By the end of dessert, I completely understood why key lime pie is such a famous Florida tradition.

To keep this recipe simple, quick, and easy, I recommend using a store-bought graham cracker crust. This keeps the total prep time to a mere 5 minutes. If you’re not a fan of store bought crusts, of course you can make your own. You can also use a regular flaky pie crust. Simply bake the crust at 425 degree F for 12-15 minutes and allow to cool at room temperate for at least 30 minutes before filling.
While this recipe is certainly not a secret, few people know that canned Key Lime pie filling even exists. It is not available in all grocery stores. When your guests marvel at how amazing the pie is, it’s up to you whether you accept all the credit or tell them that it came from a can. Lucky Leaf and Comstock are the two best known brands of canned Key Lime pie filling.
Comstock and Lucky Leaf Key Lime Pie Filling is a smooth, tangy, ready‑to‑use citrus filling designed to make key lime desserts fast and reliable. It delivers that classic bright, zesty key lime flavor with a balanced sweetness, so it tastes refreshing rather than heavy. The texture is silky and custard‑like, giving pies a clean slice and a glossy finish without any stovetop cooking or complicated steps. It’s made to pair easily with graham cracker or traditional pie crusts, making it a convenient shortcut for quick, consistent key lime pies, bars, and layered desserts.
Key lime pie made with canned filling and a premade graham cracker crust is one of the easiest ways to get that classic, bright, tangy flavor with almost no effort. The canned filling is already smooth, glossy, and perfectly balanced between tart and sweet, so it sets into a silky, custard‑like layer as it chills. Its citrus punch stays vibrant even after baking, giving the pie that refreshing, tropical character people love. When paired with the sweet, buttery crunch of a ready‑made graham crust, the contrast in textures makes each slice feel both nostalgic and indulgent.
Using a premade graham cracker crust also means the entire dessert comes together in minutes—no mixing, rolling, or blind‑baking required. The crust holds its shape well, browns lightly at the edges, and provides a sturdy base for the creamy lime filling. Add a swirl of whipped cream or a sprinkle of lime zest, and the pie looks beautifully homemade despite the shortcuts. It’s the perfect warm‑weather dessert that is bright, cool, reliable, and wonderfully simple.
