Sliced Potato Pie Recipe: Crispy Top, Creamy Vanilla Swirl Magic

This sliced potato pie recipe delivers the perfect balance of crispy, flaky top and creamy vanilla swirls that make every slice irresistible. 💛 I remember my Nonna's kitchen filled with the warm, buttery aroma of freshly baked pies—this version captures that same comforting magic with a modern twist.

The secret lies in parboiling the potatoes just right and layering them carefully for that signature texture.

The recipe starts with a classic pie crust, but the real magic happens with the potato filling. Thinly sliced potatoes absorb the creamy vanilla mixture perfectly, creating tender layers that contrast beautifully with the crisp top.

I've tested this recipe countless times to ensure the potatoes stay tender while the crust achieves that golden, shatteringly crisp finish.

What you'll end up with is a pie that looks impressive but comes together with simple techniques. The creamy vanilla swirls cut through the richness of the potatoes, while the crisp top adds that satisfying crunch with every bite.

It's the kind of dessert that feels like a warm hug—perfect for family gatherings or when you want to treat yourself.

Serve with a dollop of whipped cream or a scoop of vanilla ice cream for extra indulgence. This pie keeps well at room temperature, so you can enjoy seconds the next day. Let's get baking—your kitchen will smell like comfort food heaven in no time.

Ingredients for sliced potato pie

Six simple ingredients transform into a pie that tastes like Nonna's kitchen magic.

The potatoes are the heart of this pie—Russet is non-negotiable for that starchy texture. Grab a 3-pound bag from the grocery store's produce section (the ones with the red skins). Thinly slicing them is key—use a mandoline if you've got one, but a sharp knife works too. Parboiling for 5 minutes keeps them tender without turning mushy. I always buy extra because I can't resist seconds. For the crust, Pillsbury or homemade both work—just make sure it's chilled before using.

No heavy cream? Whole milk plus 1/4 cup melted butter gets you close. Fresh vanilla extract is worth the splurge—McCormick or Nielsen-Massey are my go-tos. The ice cream swirls can be any flavor, but vanilla keeps it classic. Store-bought pie crust saves time, but if you're feeling ambitious, make your own with the butter and flour listed. For the sugar, I divide it—half goes in the crust for sweetness, the rest in the filling to balance the creaminess. The pepper is subtle but adds depth—don't skip it!

This pie tastes even better the next day—room temperature for 2 hours before slicing. Store leftovers in an airtight container for 3-4 days (if they last that long). Freeze individual slices for 2 months by wrapping them tightly in plastic. I always make two pies—one for now, one for later. The crust gets crispier as it sits, so reheating in a 350°F oven for 10 minutes brings back that golden crunch.

Step-by-step instructions for sliced potato pie

Here's how to build that perfect balance of crispy crust and creamy potato filling.

Preheat your oven to 375°F. Peel the 3 lb Russet Potatoes and slice them ⅛-inch thick using a mandoline or sharp knife. Boil the slices in salted water for 5 minutes—they should be tender but still hold their shape when pierced with a fork.

Drain the potatoes and pat them completely dry with paper towels. Arrange the slices in a single layer on a baking sheet, overlapping slightly. Brush each layer lightly with 2 tablespoons of the melted 1 cup Unsalted Butter (reserve the rest for later). This butter will keep the layers moist while creating a golden finish.

Bake for 10 minutes until the edges begin to soften slightly. This pre-baking step prevents a soggy bottom later. Let them cool completely before assembling the pie—warm potatoes release too much moisture.

In a large bowl, whisk together the 1 cup Heavy Cream, 1.5 cups Granulated Sugar, 2 tsp Vanilla Extract, 0.5 tsp Salt, and 0.25 tsp Ground Black Pepper. The sugar should mostly dissolve, but a few tiny crystals are fine—they'll melt as it heats.

Gently fold in the 2 cups Vanilla Ice Cream using a spatula, being careful not to melt it completely. You want soft swirls that stay visible in the final pie. The mixture should be thick but pourable—if it's too stiff, stir in 1 tablespoon of the reserved melted butter.

Roll out the 1 pre-made Pie Crust to fit a 9-inch pie dish, leaving a 2-inch overhang on all sides. Press it gently into the dish, then chill in the freezer for 10 minutes to firm up. This prevents shrinking during baking.

Spread half of the pre-baked potato slices in the bottom of the crust, overlapping slightly. Pour half of the cream mixture over the potatoes, then add the remaining potato slices. Top with the remaining cream mixture, leaving a ½-inch border at the edges for the crust.

Cut the remaining 1 cup Unsalted Butter into 1-inch cubes and chill for 10 minutes. Mix the 2.5 cups All-Purpose Flour with 0.5 tsp Salt and 0.25 tsp Ground Black Pepper in a bowl. Add the cold butter cubes and use your fingers to work them into the flour until you have pea-sized crumbs.

Sprinkle the crumb mixture evenly over the pie filling, pressing down lightly. Fold the crust overhang up and around the edges, pinching to seal. Brush the crust with the 0.5 cup Ice Water to help it brown beautifully. Bake at 375°F for 45-50 minutes until the crust is golden brown and the filling is bubbly.

Let the pie cool completely on a wire rack for at least 2 hours. This resting time is crucial—it allows the filling to set properly and prevents a runny pie. The contrast between the crispy top and creamy filling will be perfect when served cold or at room temperature.

Slice with a sharp knife dipped in hot water for clean cuts. Each piece should show those beautiful vanilla ice cream swirls surrounded by tender potatoes. Serve with whipped cream if you like, but the pie is delicious on its own!

Essential equipment for great sliced potato pie

Crust Perfection Tools

First things first—your pie crust starts with the right tools. I swear by a 9-inch pie dish (I use Wilton for its sturdy, non-stick bottom) to hold everything together.

For rolling out the crust, a rolling pin with a marble base (like OXO Good Grips) gives you that perfect even thickness without tearing. Don’t skimp on the pie weights—I use Ceramic Pie Crust Weights ($10 on Amazon) to keep the bottom crisp while blind-baking if needed. 🥧

Potato Prep Essentials

A mandoline slicer (I love the OXO Good Grips model) is a game-changer for even ⅛-inch potato slices—no more uneven layers. If you don’t have one, a sharp chef’s knife and a ruler work in a pinch.

For parboiling, a large stockpot (like All-Clad Stainless Steel) fits all the slices comfortably. I also keep a fine-mesh colander nearby to drain them quickly and evenly. 🥔

Mixing and Layering

For the creamy filling, a medium mixing bowl (I use Pyrex) with a whisk attachment (like OXO’s silicone whisk) ensures smooth blending of the heavy cream and sugar. A spatula (I prefer stainless steel) helps fold in the ice cream gently without melting it prematurely.

For layering, a pie dish brush (like West Bend) comes in handy to lightly coat the potato slices with butter before baking. 🥛

Baking and Crisping

An oven thermometer (I recommend Thermoworks) is non-negotiable—your oven’s temperature gauge is often off by 25°F or more. For the crumb topping, I use my fingers (yes, really!) to mix the cold butter into the flour for that perfect pea-sized texture.

A pastry brush (like McElroy) helps apply the ice water to the crust edges for that golden-brown finish. 🔥

Cooling and Serving

Once baked, let the pie cool on a wire cooling rack (I use OXO’s non-slip rack) to prevent sogginess. For slicing, a sharp chef’s knife (I swear by Wüsthof) dipped in hot water gives clean cuts every time.

A pie server (like Wilton’s) makes serving look effortless—perfect for guests! Store leftovers in an airtight container (I use Glasslock) to keep them fresh. 🍴
