This Publix mango key lime pie recipe delivers the perfect balance of tropical sweetness and zesty citrus in every bite. The secret lies in a buttery graham cracker crust that adds a subtle crunch, while the mango nectar-infused filling brings vibrant sweetness that complements the classic key lime custard.
I've perfected this recipe after testing countless variations, ensuring the crust stays crisp, the filling stays firm, and the tangy-sweet flavors shine through without overpowering each other.
The recipe begins with a foolproof graham cracker crust that requires just five minutes of prep time and 15 minutes in the oven to achieve that ideal golden-brown texture.
For the filling, I use Publix's premium mango nectar for its rich, concentrated flavor—this is where the tropical twist truly comes alive. The key lime custard layer gets its signature tang from fresh key lime juice, but I've included a substitution option for when fresh limes aren't available.
What makes this pie stand out is the way the flavors come together: the mango filling adds a fruity depth that rounds out the tartness of the lime custard, while the graham cracker crust provides just enough texture to keep each bite interesting.
The pie bakes for 50-55 minutes at 350°F, developing a caramelized top that's irresistible. Once cooled, it's ready to be garnished with whipped cream and toasted meringue for that restaurant-quality finish.
Perfect for summer gatherings, this pie serves 8-10 and can be prepped a day ahead, making it ideal for busy hosts.
The combination of sweet, tangy, and creamy elements creates a dessert that's both impressive and approachable—guests will think you spent hours in the kitchen when the truth is, this recipe is surprisingly simple to execute. Let's get started on creating your own tropical masterpiece.

The Publix mango nectar is non-negotiable here—it’s what gives this pie that ultra-tropical vibe. Grab the premium canned version from the nectar aisle at Publix (or any well-stocked grocery store). If you can’t find it, Dole mango nectar works in a pinch. For the crust, graham crackers with no added sugar are key—Honey Maid is my go-to, but any sturdy graham cracker will do. The unsalted butter should be cold when mixing to avoid a greasy crust. Trust me, the difference between cold and room-temperature butter is huge for that perfect crunch.
No fresh key limes? Lime juice concentrate (thawed and diluted) or even regular lime juice (with a pinch of extra sugar) works. For the meringue topping, store-bought is fine (like Duncan Hines or Betty Crocker), but if you’re feeling fancy, homemade is worth the extra 10 minutes. The whipping cream for garnish should be heavy cream—none of that light stuff. And if you’re skipping the coconut flakes, a sprinkle of toasted pecans adds a nice crunch. The vanilla extract? Pure Madagascar bourbon vanilla is ideal, but imitation will do if that’s all you’ve got.
The crust can be prepped a day ahead and stored in the fridge—just press it into the pie dish and wrap it tightly. The filling keeps in the fridge for up to 3 days, though it’s best eaten within 24 hours for that perfect texture. The meringue topping? Toast it under the broiler for 2-3 minutes right before serving—don’t skip this step, or it’ll stay raw. Leftovers? Slice and freeze for up to 3 months—just thaw overnight in the fridge before serving.

Step-by-step instructions for Publix mango key lime pie
Here's how to assemble this tropical twist on a classic—crisp crust meets tangy mango-lime filling.
Bake the Graham Cracker Crust
Preheat your oven to 350°F and grease a 9-inch pie dish lightly with butter. In a large bowl, combine the 2 cups graham cracker crumbs with the 0.5 cup unsalted butter and 0.25 cup granulated sugar. Use your fingers or a fork to mix until the crumbs are evenly moistened and the mixture resembles wet sand.
Press the crumb mixture firmly and evenly into the bottom and about 1 inch up the sides of the pie dish, using a glass to compact it smoothly. Bake for 10-12 minutes until the edges are lightly golden. Let it cool completely before filling—this prevents a soggy crust. I like to chill it in the fridge for 15 minutes while I prepare the filling.
Prepare the Mango-Lime Filling
In a large mixing bowl, whisk together the 1 cup key lime juice, 15 oz Publix mango nectar, and 14 oz sweetened condensed milk until fully combined. The mixture should be smooth with no lumps. In a separate bowl, beat the 4 whole large eggs until they're well incorporated, then gradually whisk them into the mango mixture.
Add 1.5 cups granulated sugar, 1 teaspoon vanilla extract, and 0.25 teaspoon salt to the egg mixture and whisk until everything is evenly distributed. The filling should be thick but pourable—if it looks too thin, let it sit for 10 minutes to slightly thicken. This step is crucial for that perfect balance of sweet, tangy, and tropical flavors.
Assemble and Bake the Pie
Pour the mango-lime filling into the cooled crust, spreading it evenly with a spatula. Place the pie on a baking sheet to catch any spills and bake at 350°F for 40-45 minutes, or until the center is just set (it should still have a slight wobble when gently shaken). The edges should be golden, and the filling should look thickened but not dry.
Remove the pie from the oven and let it cool to room temperature. Then, refrigerate it for at least 4 hours or overnight—this allows the flavors to meld and the filling to fully set. Patience here makes all the difference in texture and taste.
Add the Meringue Topping
Once the pie is completely chilled, spread the 7 oz meringue topping evenly over the filling, sealing it to the edges to prevent shrinking. Return the pie to the oven and bake at 350°F for 8-10 minutes, until the meringue is lightly golden. Watch it closely—meringue burns quickly!
Let the pie cool completely before slicing. The meringue should be crisp on top and smooth on the sides, creating that classic pie finish. For extra flair, top with 1 cup whipped cream and 0.25 cup toasted coconut flakes right before serving.
Pro Tips For Making Publix Mango Key Lime Pie
- Melt Butter Slowly: Heat the butter for the crust over low heat—just until it’s liquid enough to mix with sugar. I used to rush this, and the crumbs would turn greasy instead of crisp. A 90-second simmer on low gives you the perfect texture without burning.
- Strain the Mango: Publix mango nectar has seeds and pulp that sink to the bottom. Pour it through a fine-mesh strainer into your mixing bowl first—this keeps your filling silky smooth and avoids that gritty mouthfeel.
- Chill the Crust Hard: Press the crust into the pan, then freeze it for 15 minutes before adding the filling. This prevents soggy bottoms later. I learned this after my first pie had a mushy crust—now it’s always crisp.
- Whisk Condensed Milk: Stir the sweetened condensed milk into the mango mixture gently with a whisk, not a spoon. This avoids lumps and ensures the filling sets evenly. A few extra strokes now saves you from a grainy texture later.
Flavor customization for publix mango key lime pie
Tropical Fruit Swaps
Swap Publix mango nectar for guava nectar or pineapple juice to change the flavor profile completely. I’ve tested this with Dole guava nectar—it adds a floral sweetness that pairs beautifully with the lime.
For a more exotic twist, try passion fruit puree (about ½ cup) mixed with the mango nectar. Just reduce the sugar slightly since these fruits are naturally sweeter. 🥭
Spice & Citrus Boost
Add ½ teaspoon ground ginger or ¼ teaspoon cinnamon to the filling for warmth. A splash of lime zest (about 1 tablespoon) brightens the flavor without altering the texture.
For heat lovers, mix ¼ teaspoon Tajín into the whipped cream garnish—it’s a game-changer. I also love a pinch of cardamom (just ⅛ teaspoon) for an aromatic depth. 🌶️
Dairy-Free Adaptations
Replace sweetened condensed milk with coconut condensed milk (like Goya) for a dairy-free version. Swap heavy whipping cream for coconut whipped cream (chill a can of full-fat coconut milk overnight, then whip the solids).
The crust stays the same, but the filling gains a subtle coconut note that complements the tropical flavors. 🥥
Texture Variations
For a cheesecake-style texture, add 8 oz cream cheese to the filling and bake at 325°F for 50-55 minutes. If you prefer crunch, sprinkle ½ cup chopped macadamia nuts or toasted almonds on top before baking the meringue.
I’ve also experimented with a caramel drizzle (melt ½ cup caramel sauce and pour over the cooled pie). 💫
Seasonal Twists
In summer, keep it light with fresh berries (raspberries or blackberries) arranged on top. For fall, swap the mango for peach nectar and add pumpkin spice to the crust.
Winter calls for gingersnap crumbs in the crust and a cranberry compote drizzle. Each season transforms the pie’s vibe while keeping the key lime tang. ❄️

Frequently asked questions
Can I make this pie without Publix mango nectar?
Use Dole mango nectar or even fresh mango puree (about 1.5 cups blended and strained). For a different tropical twist, try guava nectar or pineapple juice—just reduce the sugar slightly since these fruits are naturally sweeter. The key lime flavor will still shine through.
How do I prevent the crust from getting soggy?
Bake the crust until it's lightly golden (about 10-12 minutes at 350°F) and let it cool completely before adding the filling. For extra insurance, brush the bottom with a thin layer of apricot jam or mango nectar before baking—it creates a moisture barrier. Chill the assembled pie for at least 4 hours before slicing.
What if I don't have fresh key limes?
Use lime juice concentrate (thaw and dilute with water to match the volume) or regular lime juice with an extra 1-2 tablespoons of sugar to balance the tartness. For a deeper flavor, add 1 teaspoon lime zest to the filling. The pie will still taste amazing—just slightly less vibrant.
Can I make this pie ahead of time?
Yes! Assemble the pie (without the meringue) up to 2 days ahead and refrigerate. Add the meringue topping 1 day before serving, then broil for 2-3 minutes just before eating. The flavors actually improve overnight as the filling sets. For make-ahead convenience, bake the crust and filling separately, then combine before serving.
Why did my meringue collapse?
Meringue collapses from humidity, overbaking, or opening the oven door too soon. Let the pie cool completely before adding meringue, and bake it at 350°F for just 8-10 minutes—watch closely! If humidity is high, try a dehumidifier or bake on a lower rack. For extra stability, seal the meringue to the edges with a spatula.
