Ingredients for grandma's old fashioned potato pie
Buttery crust meets velvety spiced filling—just like grandma made it. These ingredients bring back that nostalgic, comforting flavor.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lbs | Peeled and cut into 1-inch cubes |
| Heavy Whipping Cream 🥛 | 1 ½ cups | Full-fat for optimal richness |
| Unsalted Butter 🧈 | 1 cup | Cold, cut into small cubes |
| Granulated Sugar 🍚 | ¾ cup | Light brown preferred for depth |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground for best flavor |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated preferred |
| Salt 🧂 | 1 tsp | Diamond Crystal kosher preferred |
| All-Purpose Flour 🌾 | 2 ½ cups | For crust, sifted if possible |
| Cold Unsalted Butter 🧈 | 1 cup | Cut into small cubes |
| Ice Water 💧 | ½ cup | For dough consistency |
| Egg Yolk 🥚 | 1 whole | For egg wash |
| Granulated Sugar 🍚 | 1 tbsp | For egg wash |
The Russet potatoes are the heart of this pie—firm, starchy varieties work best for that smooth texture. Buy organic if possible, as the skins can add subtle earthiness. Costco or local farmers' markets often have the freshest, most flavorful potatoes. If using conventional, scrub thoroughly to remove any wax residue. For the heavy whipping cream, full-fat is non-negotiable—it creates that luscious, rich filling that defines old-fashioned pies. Store-brand or organic both work well, but avoid ultra-pasteurized versions that can separate during cooking. The unsalted butter should be cold and cubed for the crust; Land O'Lakes or Plugrá are reliable choices for consistent quality.
No brown sugar? Substitute white sugar plus a pinch of molasses for that caramel depth. Freshly ground spices make all the difference—Penzeys or Spicewalla offer premium options, but regular grocery store brands work fine if labeled 'freshly ground.' For the crust, shortening can replace butter if you prefer a flakier texture, though the flavor won't be as rich. Diamond Crystal kosher salt dissolves more easily, but Morton iodized works in a pinch. The ice water is crucial—use actual ice cubes for the coldest possible water, which helps create tender layers in the dough. If you're short on time, chilled water from the fridge works, though it may require a bit more flour for binding.
The potato filling keeps well for 4-5 days in the fridge, while the assembled pie is best enjoyed within 2 days for peak crust crispness. Freeze the filling before baking for up to 3 months—just thaw overnight before assembling. The crust mix can be prepped 24 hours ahead and stored in the fridge, saving you time on baking day. Portion the filling into ramekins for individual servings if you're making mini pies. Reheat slices at 350°F for 10-15 minutes to restore that golden-brown crust—broil for 2 minutes at the end for extra crispiness.

Step-by-step instructions for grandma's old fashioned potato pie
A classic homestyle pie where silky potato filling meets a tender, flaky crust. Follow these precise steps for perfect texture every time.
Prepare the Potato Filling
Begin by boiling the 3 lbs of peeled and cubed russet potatoes in salted water until fork-tender, which should take about 20-25 minutes. Drain thoroughly and return them to the pot. Add the 1.5 cups heavy whipping cream and 1 cup unsalted butter, stirring until the butter melts completely and the mixture becomes smooth.
In a small bowl, whisk together the 0.75 cup granulated sugar, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, and 1 tsp salt. Gradually sprinkle this spice mixture over the warm potato mixture while stirring continuously. The filling should be thick but still spreadable—if it's too thick, add 1-2 tablespoons of cream to reach the ideal consistency. Let the filling cool completely before assembling the pie.
Make the Classic Pie Crust
In a large mixing bowl, combine the 2.5 cups all-purpose flour and 1 tsp salt. Cut in the 1 cup cold unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces remaining. This cold butter creates the flaky layers that define a perfect crust.
Slowly drizzle in the 0.5 cup ice water, one tablespoon at a time, mixing gently with a fork just until the dough comes together. Be careful not to overwork it—handle only enough to form a cohesive mass. Divide the dough into two equal portions, flatten into disks, wrap in plastic, and refrigerate for at least 30 minutes while you prepare the filling.
Assemble the Pie
Preheat your oven to 375°F. Roll out one disk of chilled dough on a lightly floured surface to fit a 9-inch pie dish, about 1/8-inch thick. Gently press it into the dish, trimming any excess dough hanging over the edges. Pour the cooled potato filling into the crust, spreading it evenly to within 1/2-inch of the edge. This prevents a soggy bottom.
Roll out the second dough disk and place it over the filling. Crimp the edges by folding the top crust over the bottom crust and pressing firmly with your thumb or a fork to seal. Cut a few slits in the top crust to allow steam to escape during baking. Brush the entire surface with an egg wash made by whisking the 1 whole egg yolk and 1 tbsp granulated sugar until smooth.
Bake to Golden Perfection
Place the assembled pie on a baking sheet lined with parchment paper to catch any drips. Bake in the preheated oven for 45-50 minutes, until the crust is deep golden brown and the filling is bubbling gently through the slits. The pie is done when the internal temperature reaches 190°F—this ensures the filling is fully set.
Remove the pie from the oven and let it cool on a wire rack for at least 2 hours before slicing. This resting period allows the filling to firm up and the juices to redistribute, preventing a runny pie. Serve warm with a dollop of whipped cream or a scoop of vanilla ice cream for the ultimate homestyle experience.
Pro Tips For Making Grandma'S Old Fashioned Potato Pie
- BOIL POTATOES UNTIL TENDER: Russets stay dry when overcooked—aim for a fork that slides in like butter, not a knife fight. Drop them in cold salted water (yes, even if you’re impatient like me) and boil until they’re just collapsing, about 15-20 minutes. Overcooking turns them into glue, and nobody wants a pie that’s basically mashed potato soup.
- WHISK CREAM COLD: Heavy whipping cream loves the cold. Chill your mixing bowl and beaters for 10 minutes before folding in the cream—this prevents curdling and gives you that silky, not-greasy texture. I learned this the hard way after a batch separated like oil and water.
- SALT THE POTATO WATER: Skip this, and your pie tastes bland. Generously salt the boiling water (like you’re seasoning soup) so the potatoes absorb flavor from the start. The salt also helps tenderize them faster—no one wants to wait 25 minutes for mushy spuds.
- BAKE UNTIL GOLDEN CRUST: That top layer isn’t just for looks—it’s the deal. Bake the pie at 350°F until the crust is deep golden, not just pale. If it’s browning too fast, tent it with foil early, then uncover to crisp. My grandmother’s rule: “If it’s not golden, it’s not done.” (And yes, she was right.)
Essential equipment for great grandma's old fashioned potato pie
Pie Dish Essentials
Start with a 9-inch glass or ceramic pie dish—it distributes heat evenly and prevents soggy bottoms. I prefer Corelle stoneware for its durability and even baking. Avoid dark-colored metal dishes, which can overbrown the crust.
For a rustic touch, cast iron skillets work too, but preheat them longer to prevent cracking. Always use a pie dish with a removable bottom if possible, making slicing easier. 🥧
Dough Tools
A rolling pin is a must for achieving that perfect 1/8-inch thickness for both crust layers. I love the OXO Good Grips model—its non-slip handle prevents dough from sticking. For shaping, keep a sharp chef’s knife and a bench scraper nearby to trim excess dough cleanly.
A pastry brush (like West Bend’s silicone brush) helps apply egg wash evenly without drips. 🧑🍳
Mixing & Measuring
Precision matters in pie crusts! Use a digital kitchen scale (I recommend OXO’s 11lb model) for accurate measurements—2.5 cups flour can vary by brand. A pastry cutter (like La Bounty’s stainless steel) is ideal for cutting butter into flour, but two forks work in a pinch.
For mixing the filling, a medium-sized stainless steel pot (like All-Clad’s 3-quart) handles the potatoes perfectly. 🥄
Baking Gear
Line your baking sheet with parchment paper to catch drips and ensure even heat distribution. A pie cooling rack (like McElroy’s wire rack) prevents soggy bottoms by allowing air circulation.
For temperature control, invest in an instant-read thermometer (I use ThermoWorks’ Smoke) to monitor the filling’s 190°F internal temp. A pizza stone on the lower oven rack during baking creates a crispier crust. 🔥
Optional Upgrades
For a lattice top, use a pastry wheel (like Mercer Culinary’s) to cut clean strips. A pie crimper (like OXO’s) makes sealing edges effortless. If you love shortcuts, pre-made pie crusts (like Pillsbury’s) work in a pinch—just brush with extra egg wash for crispiness.
For extra flakiness, chill your dough an additional 30 minutes before rolling. ✨

Frequently asked questions
Can I make this potato pie ahead of time?
The filling can be prepared 2 days ahead and stored in the refrigerator. For the full pie, assemble it 1 day before baking and refrigerate uncovered. Bake when ready, adding 5-10 minutes to the baking time. The crust will need extra time to crisp up after chilling.
Why does my crust turn out soggy?
Soggy crusts happen when moisture escapes through the top or bottom. Always leave a 1/2-inch border between filling and crust edge, and cut steam vents in the top crust. For extra insurance, blind-bake the bottom crust for 10 minutes at 375°F before adding filling. Chill the pie 2 hours before slicing to let juices set.
What's the secret to that perfect flaky crust?
The magic is in keeping everything cold! Use cold butter cut into small cubes, and chill the dough at least 30 minutes before rolling. Work quickly when handling dough, and avoid overmixing. The ice water helps create those signature flaky layers. For extra flakiness, freeze the dough balls for 15 minutes before rolling.
Can I substitute sweet potatoes?
While you can use sweet potatoes, they'll change the flavor profile significantly. Sweet potatoes add natural sweetness and moisture that may require adjusting the sugar to 0.5 cup and adding 1/4 cup extra cream to balance the filling. The texture will also be slightly denser. For an authentic experience, stick with russet potatoes.
How do I make this pie gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free flour blend (like Bob's Red Mill) for the crust. Add 1/2 tsp xanthan gum to help bind the dough. For the filling, ensure your spices are certified gluten-free. The texture may be slightly different, but the flavor remains rich and comforting.
