Ingredients for old fashioned leek and potato pie
The heart of this pie starts with tender potatoes and leeks, wrapped in a rustic buttermilk crust.
| Ingredient | Amount | Notes |
|---|---|---|
| Yukon Gold Potatoes 🥔 | 2 ½ lb | Medium size, peeled and cubed |
| Leeks 🧅 | 3 whole | White and light green parts, sliced thin |
| Unsalted Butter 🧈 | ¾ cup | Cold, cut into small pieces |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Fresh Thyme Leaves 🌿 | ¼ cup | Stems removed, finely chopped |
| Fresh Parsley Leaves 🌿 | ¼ cup | Flat-leaf preferred, chopped |
| Ground Nutmeg 🌶️ | ¼ tsp | Freshly grated preferred |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| All-Purpose Flour 🌾 | 2 ½ cups | For crust, sifted |
| Buttermilk 🥛 | 1 cup | Cold, for crust |
| Cold Unsalted Butter 🧈 | ½ cup | Cubed, for crust |
| Ice Water 💧 | ½ cup | For dough consistency |
| Egg 🥚 | 1 whole | For egg wash |
The Yukon Gold potatoes are non-negotiable—their buttery texture makes all the difference. Buy them fresh from a local market or the produce section, avoiding any with sprouts. Leeks need thorough cleaning since dirt hides between layers, so rinse them well under running water. For the crust, King Arthur flour is my go-to, but any all-purpose works. The buttermilk should be cold—this keeps the crust flaky. If you can't find fresh thyme, dried works at one-third the amount, but fresh is worth the hunt at Whole Foods or your local farmers market.
No buttermilk? Mix 1 tablespoon lemon juice or vinegar with 1 cup milk and let sit for 5 minutes. Short on heavy cream? Half-and-half plus a splash of milk works, but the texture won't be as rich. The nutmeg should be freshly grated—pre-ground loses flavor fast. For the crust, if you're nervous about handling cold butter, microwave it for 20 seconds to soften slightly before cutting into cubes. And trust me on the ice water—it keeps the dough from getting gummy.
This pie keeps beautifully—3-4 days in the fridge for maximum freshness, though it reheats just as well. Wrap tightly with foil to preserve that flaky crust. For serving, a quick broil for 2-3 minutes under the oven's broiler gives the top a golden finish. Leftovers? Slice and reheat in a 350°F oven for 15 minutes—the crust stays crispy, and the filling gets that comforting second-bake warmth.

Step-by-step instructions for old fashioned leek and potato pie
Here's how to create a hearty, rustic pie with a golden crust and velvety herbed filling.
Prepare the Potato-Leek Filling
Preheat your oven to 375°F. In a large pot, combine the 2.5 lb Yukon Gold Potatoes (peeled and cubed) and 3 whole Leeks (white and light green parts, sliced thin). Add 1 cup Heavy Cream, 0.5 tsp Black Pepper, and 1 tsp Salt to the pot. Bring to a boil, then reduce heat to medium-low and simmer for 15-20 minutes until the potatoes are fork-tender.
While the potatoes cook, melt 0.5 cup Unsalted Butter in a separate skillet over medium heat. Add the 0.25 cup Fresh Thyme Leaves and 0.25 cup Fresh Parsley Leaves, cooking for 1-2 minutes until fragrant. Stir in the 0.25 tsp Ground Nutmeg and 0.5 tsp Salt. Once the potatoes are tender, drain them well and mash slightly with a potato masher or fork. Fold in the herbed butter mixture, mixing until fully combined. The filling should be smooth but still slightly chunky. Let it cool for 10 minutes before assembling the pie.
Make the Rustic Crust
In a large bowl, whisk together the 2.5 cups All-Purpose Flour, 1.5 tsp Salt, and 0.5 tsp Black Pepper. Cut in the 0.5 cup Cold Unsalted Butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Add the 1 cup Buttermilk and mix until just combined. The dough should come together but not be sticky.
Turn the dough out onto a lightly floured surface and knead gently for 1-2 minutes until smooth. Divide the dough into two equal pieces. Roll one piece into a 12-inch circle for the bottom crust, and roll the second piece into a slightly smaller circle for the top crust. If the dough feels too sticky, wet your hands slightly as you handle it. Keep the unused dough covered with a damp towel while you prepare the pie dish.
Assemble and Bake the Pie
Grease a 9-inch deep-dish pie dish lightly with butter. Line the bottom of the dish with the rolled-out bottom crust, pressing gently to fit it into the dish. Trim any excess dough hanging over the edges. Pour the cooled potato-leek filling into the crust, spreading it evenly. The filling should come about ¾ of the way up the sides of the pie dish.
Roll out the second piece of dough for the top crust and place it over the filling. Trim any excess dough and press the edges together to seal. Use a fork to crimp the edges decoratively. Cut a few small slits in the top crust to allow steam to escape. In a small bowl, beat the 1 whole Egg with 1 tablespoon Ice Water and brush the egg wash over the top crust. Sprinkle with a pinch of Salt for extra flavor.
Bake to Golden Perfection
Place the pie on a baking sheet lined with parchment paper to catch any drips. Bake in the preheated 375°F oven for 45-50 minutes until the crust is deep golden brown and the filling is bubbling through the slits in the top crust. If the crust starts to brown too quickly, cover the edges loosely with aluminum foil to prevent over-browning.
Remove the pie from the oven and let it cool for 15 minutes before slicing. The filling should be creamy and flavorful, with a hint of nutmeg warmth. Serve warm with a simple side salad or steamed green vegetables. This pie tastes even better the next day, so plan ahead if you can! The crust will stay crisp, and the filling will deepen in flavor as it rests.
Pro Tips For Making Old Fashioned Leek And Potato Pie
- Parboil Potatoes First: Cut those Yukon Golds into even ½-inch slices, then boil them in salted water for 3-4 minutes before adding to the pie. This guarantees they’ll finish tender without turning to mush—no more dry patches or gummy centers. (Yes, even if you’re impatient like me, resist the urge to skip this.)
- Sweat Leeks Low: After slicing leeks thinly, cook them in butter over low heat for 10-12 minutes until they’re soft and golden, not browned. High heat burns them before they release their sweetness, and you’ll end up with bitter, sad leeks instead of the rich, mellow base the pie needs.
- Don’t Skip the Cream Rest: Once you stir heavy cream into the potato-leek mixture, let it sit off the heat for 5 minutes before baking. This lets the starches settle, so the filling stays silky smooth instead of turning gluey. (Your future self will thank you—trust me.)
- Thyme Early, Thyme Often: Toss fresh thyme leaves into the butter when you start cooking the leeks, not just at the end. The flavor infuses deeper this way, and you won’t have to worry about wilting sprigs floating on top. (Pro move: Use 2 tablespoons chopped leaves—more than you’d think.)
Creative variations of this old fashioned leek and potato pie
Herbed Cheese Twist
Add ½ cup shredded Gruyère or Comté cheese to the filling before baking for a nutty, savory depth. I fold it into the mashed potato-leek mixture along with the herbed butter. The cheese melts into the filling, creating pockets of rich, gooey goodness that contrast beautifully with the flaky crust.
For extra flavor, sprinkle ¼ cup grated Parmesan over the top crust before baking—it crisps into a golden blanket. 🧀
Smoky Bacon Crust
Swap the buttermilk crust for one with crispy bacon by cooking 6 slices of thick-cut bacon until crisp, then crumbling it into the dough. This adds a smoky, salty punch that pairs perfectly with the earthy leeks and potatoes.
I like to use Applewood-smoked bacon for extra depth. For a shortcut, buy pre-cooked bacon and crumble it directly into the flour mixture before adding the buttermilk. 🥓
Spinach & Feta Layer
Add a layer of wilted spinach and crumbled feta between the bottom crust and filling for a Mediterranean twist. Sauté 4 cups fresh spinach with 2 minced garlic cloves until just wilted, then mix with ½ cup crumbled feta cheese.
Spread this over the bottom crust before adding the potato-leek filling. The tangy feta cuts through the richness, while the spinach adds a subtle earthiness. 🌿
Spiced Apple Topping
For a sweet-savory balance, top the pie with thinly sliced tart apples (like Granny Smith) before baking. Toss the slices with 1 tsp cinnamon, ½ tsp nutmeg, and 1 tbsp brown sugar to caramelize.
Arrange them decoratively over the top crust. The apples soften during baking, releasing juices that mingle with the filling for a delightful contrast. 🍎
Creamy Gouda Swirl
Create a marbled effect by swirling ½ cup melted sharp cheddar or Gouda into the filling before baking. Use a knife to drag lines through the filling, then sprinkle extra cheese on top.
The melted cheese creates beautiful swirls that add visual appeal and extra richness. For a bolder flavor, mix in 1 tbsp Dijon mustard with the melted cheese. 🧈
Pesto-Inspired Filling
Boost the herb profile by blending ½ cup fresh basil, ¼ cup pine nuts, 2 cloves roasted garlic, and ¼ cup olive oil into a pesto. Fold this into the filling along with the herbed butter for a bright, herby twist.
The pine nuts add a delightful crunch, while the garlic deepens the savory notes. Store-bought pesto works in a pinch, but fresh is worth the effort. 🌱

Frequently asked questions
Can I make this pie without a buttermilk crust?
Swap the buttermilk for 1 cup cold milk + 1 tablespoon vinegar or lemon juice to mimic buttermilk's tang. For a richer crust, try 1 cup sour cream or Greek yogurt instead—just chill the dough longer before rolling to prevent stickiness. The flavor will be slightly different but still delicious.
How do I prevent a soggy bottom crust?
Always pre-bake the bottom crust for 10 minutes at 375°F before adding filling. Brush it lightly with egg wash afterward to create a moisture barrier. Another trick: sprinkle ½ cup crushed cornflakes or almond flour between the crust and filling to absorb excess moisture.
Can I use sweet potatoes instead of Yukon Gold?
Yes, but adjust the seasoning! Sweet potatoes have a naturally sweeter, denser texture. Reduce the nutmeg to ¼ teaspoon and add ½ teaspoon cinnamon to complement their flavor. You may also need 1 extra tablespoon of cream to balance their moisture content.
Why did my crust turn out tough instead of flaky?
Overworking the dough or using warm butter are the most common culprits. Keep everything cold (including your hands!) and handle the dough minimally. For extra flakiness, cut the butter into ¼-inch cubes and fold them into the flour like "coins" rather than cutting them in. Also, avoid overbaking—the crust should be golden, not brown.
How far ahead can I prepare the filling?
The filling can be made 1 day ahead and stored in the fridge. Reheat it gently in a saucepan with a splash of cream until warmed through. For best texture, assemble the pie just before baking, but you can prep the crust separately and refrigerate it overnight. The flavors actually improve after resting!
