Desserts
This old-fashioned leek and potato pie delivers the comforting warmth of a classic savory dessert that feels like a hug from your great-grandmother's kitchen. The secret lies in a rich, herbed filling of tender potatoes and delicate leeks, all encased in a golden, flaky crust that crackles with every bite.
I've perfected this recipe over years of testing, ensuring the crust stays crisp while the filling remains velvety and flavorful.
The beauty of this pie is in its simplicity—just a handful of ingredients transform into something extraordinary. A well-seasoned potato-leek mixture forms the heart of the pie, while a traditional pie crust provides that satisfying crunch.
The herbs, typically thyme and parsley, add depth without overpowering the natural flavors of the vegetables. What sets this apart is the balance: the crust must be sturdy enough to hold the filling but delicate enough to melt in your mouth.
What you'll end up with is a pie that's hearty enough to serve as a main dish yet elegant enough for special occasions. The golden crust contrasts perfectly with the creamy, herbed filling, creating a dish that's both rustic and refined.
Each slice offers layers of texture and flavor—crisp crust, tender potatoes, and aromatic leeks—that make it impossible to resist a second helping.
Best of all, this pie reheats beautifully, making it perfect for meal prep or leftovers. Whether you're hosting a dinner party or simply craving a comforting meal, this recipe delivers restaurant-quality results with minimal effort. Let's get started on creating this timeless classic.
Ingredients for old fashioned leek and potato pie
Just 14 ingredients transform into a pie that tastes like homecoming every time.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lb | Peeled and thinly sliced |
| Leeks 🧅 | 3 large | White and light green parts only |
| Unsalted Butter 🧈 | ¾ cup | Cold, cut into small pieces |
| Heavy Cream 🥛 | 1 cup | Full-fat for creaminess |
| All-Purpose Flour 🌾 | 1 ½ cups | For pie crust |
| Cold Water 💧 | ½ cup | Plus ice for chilling dough |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Fresh Thyme 🌿 | 1 tbsp | Leaves only, finely chopped |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Garlic Cloves 🧄 | 2 cloves | Minced for filling |
| Egg 🥚 | 1 large | For egg wash |
| Milk 🥛 | 1 tbsp | For egg wash |
| Granulated Sugar 🍚 | 1 tbsp | For crust sprinkle |
The leeks are the star here—clean them well, slicing off the dark green tops and cutting the white/light green parts into thin half-moons. Whole Foods or Trader Joe's usually carry the freshest, but any grocery store will do. I always double-check for crispness—no wilted or slimy spots. The potatoes? Russets are non-negotiable—they hold their shape better than Yukon Golds in this dish. For the crust, King Arthur flour is my go-to, but any all-purpose works if you're in a pinch. Keep everything cold until you're ready to roll out the dough—it makes all the difference for that perfect flaky texture.
No fresh thyme? Dried works at one-third the amount, but fresh has that bright aroma you can't beat. Short on butter? Vegetable shortening keeps the crust flaky, though it won't taste as rich. The heavy cream can be swapped for half-and-half if needed, but trust me on the full-fat version—it makes the filling silky. For the leeks, if you can't find them fresh, frozen chopped leeks (thawed and drained) work in a pinch. Just don't skip the mincing the garlic—it's what ties all the flavors together. And if you're feeling fancy, sprinkle a pinch of nutmeg into the filling for that classic old-fashioned touch.
This pie keeps beautifully—3-4 days in the fridge, 2 months frozen. I always make an extra crust and freeze it separately for future pies. The filling can be prepped ahead and refrigerated for 1 day before baking. For serving, a quick brush with melted butter and 5 minutes under the broiler gives that golden finish. Leftovers reheat perfectly—just wrap them in foil and warm in a 350°F oven for 15 minutes. The crust stays crisp, and the filling gets that comforting second-life warmth.

Step-by-step instructions for old fashioned leek and potato pie
Here's how to create a comforting pie with layers of flaky crust and herbed potato-leek filling.
Prepare the Potato-Leek Filling
Peel the 3 lb russet potatoes and slice them into ⅛-inch thick rounds. You'll want about 6 cups of sliced potatoes. Soak the slices in cold water for 10 minutes to remove excess starch, then drain well and pat dry with paper towels.
Clean the 3 large leeks thoroughly, then slice off the white and light green parts only, discarding the dark green tops. Thinly slice the leeks lengthwise into ¼-inch strips. In a large skillet, melt 2 tablespoons of the 0.75 cup unsalted butter over medium heat. Add the leeks and cook for 8-10 minutes until softened but not browned.
In a separate large bowl, combine the cooked leeks with the potato slices. Add the 1 cup heavy cream, 1 tbsp finely chopped fresh thyme, 0.25 cup chopped fresh parsley, 0.5 tsp black pepper, and the 2 minced garlic cloves. Stir gently to combine. Season with 1 tsp of the 1.5 tsp salt. The filling should look creamy and fragrant with visible potato slices and wilted leeks.
Make the Pie Crust
In a large mixing bowl, combine the 1.5 cups all-purpose flour and the remaining 0.5 tsp salt. Cut in the remaining 0.5 cup cold unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. Sprinkle in 0.5 cup cold water, 1 tablespoon at a time, mixing gently with a fork until the dough just comes together.
Turn the dough out onto a lightly floured surface and knead lightly for 1 minute until smooth. Divide the dough into two equal parts. Roll out one half into a 12-inch circle for the bottom crust. Transfer it to a 9-inch pie dish, pressing gently to fit. Roll out the second half for the top crust, keeping it slightly larger than the pie dish.
Assemble and Bake the Pie
Preheat your oven to 375°F. Spread the potato-leek filling evenly into the pie crust, mounding it slightly in the center. Brush the edges of the bottom crust with the beaten egg mixed with 1 tbsp milk. Place the top crust over the filling, trimming any excess dough. Cut 4 slits in the top crust to allow steam to escape.
Brush the top crust with the remaining egg wash. Sprinkle evenly with the 1 tbsp granulated sugar. Bake for 50-55 minutes until the crust is golden brown and the filling is bubbling through the slits. If the edges brown too quickly, cover them with aluminum foil.
For the final step, remove the pie from the oven and let it rest for 15 minutes before slicing. This resting time allows the filling to set slightly, making it easier to serve. The pie will be warm and inviting with a golden crust and creamy, herbed potato filling that captures all the comforting flavors of a classic family recipe.
Pro Tips For Making Old Fashioned Leek And Potato Pie
- Parboil Potatoes First: Toss whole Russets in boiling water for 5 minutes before slicing—this keeps them from falling apart when you later simmer them in the cream. I learned this the hard way after watching a batch of potatoes turn to mush mid-cooking.
- Sweat Leeks Low and Slow: Cook leeks in butter over medium-low heat for at least 15 minutes, stirring often, until they’re translucent and just starting to caramelize. Rushing this step makes the filling taste raw and bitter—no one wants that.
- Skip the Overmixing: Once you add flour to the cream-butter mixture, stir just until combined—lumps are fine. Overworking it turns the filling gluey instead of silky smooth. Trust me, your pie’s texture will thank you.
- Blind-Bake the Crust: Roll out the dough, press it into the pan, then prick the bottom with a fork and weigh it down with pie weights or dried beans. Bake at 375°F (190°C) for 10 minutes before adding filling—this prevents a soggy bottom. (Yes, even if you’re impatient like me.)
Best sauces and condiments for this dish
Creamy Thyme Butter
This rich, herbed butter elevates the pie by adding depth to the potato-leek filling. Melt 2 tablespoons of the reserved unsalted butter with 1 tbsp finely chopped fresh thyme and ½ tsp black pepper over low heat until fragrant (about 1-2 minutes).
Stir this into the filling just before assembling the pie. The thyme's aroma will infuse the entire dish, creating a cohesive flavor profile that feels nostalgic and homey. 🌿
Herb-Infused Cream Sauce
For an extra-luxurious filling, make a quick herb-infused cream sauce by heating ½ cup heavy cream with 1 tbsp chopped fresh parsley and ½ tsp minced garlic in a small saucepan over low heat until just simmering. Remove from heat, cover, and let steep for 5 minutes.
Stir this into the filling before baking—it adds a velvety texture and brightens the flavors. I find this works especially well if you're serving the pie with a side salad or crusty bread. 🥛
Garlic-White Wine Pan Sauce
After baking, transform any leftover filling or drippings into a silky pan sauce. Sauté 2 minced garlic cloves in 1 tbsp butter until fragrant, then deglaze the pie dish with ¼ cup dry white wine (like Sauvignon Blanc).
Simmer for 3-4 minutes until slightly reduced, then whisk in 2 tbsp heavy cream. Drizzle this over individual slices for a restaurant-worthy touch. The wine adds a subtle acidity that cuts through the richness. 🍷
Crispy Onion Jam
For a sweet-savory contrast, caramelize ½ cup thinly sliced yellow onions in 1 tbsp butter over medium-low heat for 20 minutes until golden. Add 1 tbsp brown sugar and 1 tsp apple cider vinegar, then cook another 5 minutes until jam-like.
Spread a thin layer on the bottom crust before adding the filling—this adds a caramelized depth that pairs beautifully with the herbed potatoes. 🧅
Cheesy Béchamel Topping
For a decadent twist, replace the top crust with a creamy béchamel. Mix ½ cup milk, 2 tbsp butter, 2 tbsp flour, and ¼ cup shredded Gruyère cheese until smooth, then spread over the filling before baking.
The cheese melts into a golden, bubbly topping that adds a nutty richness. This works especially well if you're serving the pie as a main dish. 🧀
Post-Bake Drizzles
Finish your pie with a drizzle of truffle oil (just ½ tsp) for an earthy, luxurious note, or a touch of honey** (about 1 tsp) for a subtle sweetness.
Both options add visual appeal and an extra layer of flavor. I love the contrast of truffle oil with the herbed filling—it feels unexpectedly elegant for a home-cooked pie. 💫

Frequently asked questions
Can I make this pie ahead of time?
This savory pie actually tastes even better the next day. The filling sets beautifully, and the crust maintains its flakiness. Assemble the pie up to 24 hours ahead, cover it tightly, and refrigerate. Bake it straight from the fridge—just add 10-15 extra minutes to the baking time at 375°F.
What if I don't have fresh thyme?
Use 1 teaspoon dried thyme instead—just reduce the amount since dried herbs are more concentrated. For extra flavor, add ½ teaspoon of nutmeg or a pinch of smoked paprika to complement the earthy notes. The pie will still taste delicious, though fresh thyme gives that bright, aromatic quality.
How do I prevent a soggy bottom crust?
Prevent sogginess by pre-baking the bottom crust for 8-10 minutes before adding the filling. For extra insurance, sprinkle ½ cup of crushed cornflakes or breadcrumbs on the crust before filling. This creates a barrier that absorbs moisture, keeping the crust crisp.
Can I substitute Yukon Gold potatoes?
Yukon Golds work, but they'll make the filling creamier and slightly less firm. For the classic texture, stick with Russet potatoes—they hold their shape better and absorb flavors without turning mushy. If using Yukons, reduce the heavy cream to ½ cup to balance the moisture.
Is this pie suitable for vegetarians?
Yes! This recipe is naturally vegetarian—just confirm your butter and cream are dairy-free if needed. For a vegan version, use plant-based butter and coconut cream, and brush the crust with a flax egg wash (1 tbsp ground flaxseed + 3 tbsp water). The flavors remain rich and satisfying.
