Ingredients for canned corned beef pie
Six ingredients transform canned corned beef into a showstopping pie—creamy, salty, and perfectly golden.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Corned Beef 🥩 | 1 lb | Drained, shredded or chopped |
| Russet Potatoes 🥔 | 3 lb | Peeled, boiled until tender |
| Sweet Potatoes 🍠 | 1 ½ lb | Peeled, cubed, cooked until soft |
| Yellow Onions 🧅 | 2 whole | Diced, sautéed until golden |
| Unsalted Butter 🧈 | ¾ cup | Full-fat for creaminess (or dairy-free alternative) |
| Whole Milk 🥛 | 1 cup | Warmed for smooth mash |
| All-Purpose Flour 🌾 | 2 cups | For pie crust and thickening |
| Cold Water 💧 | ¾ cup | For pie crust dough |
| Salt 🧂 | 1 ½ tsp | Adjust to taste (corned beef is salty) |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked for heat |
| Ground Nutmeg 🌿 | ¼ tsp | Freshly grated for warmth |
| Granulated Sugar 🍚 | 1 tbsp | Balances corned beef saltiness |
| Garlic Powder 🧄 | 1 tsp | For depth of flavor |
| Vegetable Oil 🫒 | 2 tbsp | For crust and filling |
The corned beef is the star, so pick a quality canned brand—Hormel or Libby's work best. Sweet potatoes add natural sweetness to balance the saltiness, and Russet potatoes (not red or Yukon gold) give the filling that perfect fluffiness. For the crust, store-bought pie crust works fine, but homemade is worth it if you're feeling fancy. The key to the mashed potato topping is using hot potatoes and warm milk—this ensures a smooth, creamy texture that crisps beautifully in the oven. If you're short on time, instant potatoes (like Idahoan) cut prep time in half without sacrificing flavor.
No sweet potatoes? Extra Russet potatoes plus a pinch of cinnamon works in a pinch. Short on butter? Olive oil or vegan butter keeps it creamy, though the flavor will shift slightly. For the crust, shortening instead of butter makes it flakier but less flavorful. The corned beef is already salty, so go light on added salt—taste as you go! If you're feeling adventurous, add a splash of beef broth to the filling for extra richness. And if you're making this ahead, bake the filling only, then assemble and bake the topping the next day—it reheats beautifully.
This pie tastes even better the next day, so make it a day ahead if possible. Store leftovers in the fridge for up to 5 days, reheating in the oven at 350°F until the topping is crispy again. For freezing, bake the filling only, then freeze the assembled pie (unbaked) for up to 3 months. Thaw overnight in the fridge before baking. The crust gets crispy again after reheating, so don't worry about sogginess. And if you're serving it at a gathering, bake it in a deep dish pie pan—it looks impressive and holds more filling!

Step-by-step instructions for canned corned beef pie
Here's how to create a hearty, comforting pie that balances rich corned beef with velvety mashed potato crown.
Prepare the Corned Beef Filling
Preheat your oven to 375°F. In a large skillet, heat 2 tablespoons vegetable oil over medium heat. Add the 2 whole yellow onions that have been diced and cook for 8-10 minutes until they're soft and golden brown. This caramelization adds incredible depth to the filling.
Drain and shred the 1 lb canned corned beef using two forks, then add it to the skillet with the onions. Stir in 1 teaspoon garlic powder, 1 tablespoon granulated sugar, and 0.5 teaspoon ground black pepper. Cook for another 5 minutes to let the flavors meld together. The sugar helps balance the saltiness of the corned beef while the garlic powder adds warmth.
Transfer the corned beef mixture to a 9-inch pie dish and spread it evenly. This will be the flavorful base for your pie. Set aside while you prepare the mashed potato crown.
Make the Creamy Mashed Potato Crown
In a large pot, combine the 3 lb peeled russet potatoes and 1.5 lb peeled, cubed sweet potatoes. Cover with cold water by about 2 inches and bring to a boil over high heat. Once boiling, reduce heat to medium-low and simmer for 15-20 minutes until both potatoes are fork-tender.
Drain the potatoes thoroughly, then return them to the pot. Add 0.75 cup unsalted butter and 1 cup whole milk. Using a potato masher or ricer, mash until completely smooth. Season with 1.5 teaspoons salt, 0.25 teaspoon ground nutmeg, and 0.5 teaspoon ground black pepper. The nutmeg adds a subtle warmth that complements the rich flavors of the corned beef.
Spread the mashed potato mixture evenly over the corned beef filling in the pie dish. The combination of russet and sweet potatoes creates a perfect balance of textures and flavors. Smooth the top with a spatula for an even surface.
Prepare the Pie Crust
In a medium bowl, combine 2 cups all-purpose flour and 1.5 teaspoons salt. Cut in 0.75 cup unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Add 0.75 cup cold water and mix just until the dough comes together.
Turn the dough onto a lightly floured surface and knead gently for 1 minute until smooth. Divide the dough into two equal parts. Roll out one portion to fit the top of your pie dish, leaving enough dough to create a 1-inch overhang. Roll out the second portion for the bottom crust.
Carefully transfer the bottom crust to the pie dish and press it gently into the edges. Pour in the mashed potato and corned beef filling, then cover with the top crust. Seal the edges by pinching them together firmly. Cut a few small slits in the top crust to allow steam to escape during baking.
Bake to Golden Perfection
Brush the top crust with a beaten egg (optional but recommended for a golden finish) and bake in the preheated 375°F oven for 45-50 minutes until the crust is golden brown and the filling is bubbling at the edges. The pie is done when the crust is deep golden and the filling is heated through.
Remove the pie from the oven and let it rest for 15-20 minutes before slicing. This resting period allows the filling to set slightly, making it easier to serve. The result is a beautifully layered pie with a rich, savory corned beef filling topped with a creamy mashed potato crown and a flaky crust.
Serve warm with a simple green salad or crusty bread to complete the meal. This pie is perfect for a comforting family dinner or a special occasion when you want to impress with a hearty, home-cooked dish.
Pro Tips For Making Canned Corned Beef Pie
- Pre-Cook the Sweet Potatoes: I learned this the hard way—raw sweet potatoes in a pie turn to glue. Parboil them for 8-10 minutes until fork-tender, then drain and mash them with the butter. This keeps the texture light and prevents a sad, gummy filling.
- Shred the Onions Fine: Skip the big chunks—you want the onions to melt into the filling, not sit as identifiable bits. Pulse them in a food processor for 10 seconds, then stir them into the corned beef with the potatoes. The flavor spreads evenly, and the pie tastes richer.
- Don’t Overmix the Filling: Once you fold in the mashed potatoes and onions, stop stirring the second everything looks combined. Overmixing makes the filling dense and heavy. A few streaks of corned beef juice are fine—they add depth.
- Blind-Bake the Crust: If you’re using a store-bought crust, weigh it down with pie weights or dried beans for 10 minutes at 375°F before adding the filling. This prevents a soggy bottom, and the extra time ensures the crust holds up to the juicy corned beef. (Yes, even if you’re impatient like me.)
Pro cooking tips for this dish
Filling Flavor Balance
The corned beef's saltiness needs careful balancing—start by sautéing onions until deeply caramelized (10 minutes on medium heat) to develop sweetness. Add 1 tbsp sugar to the filling to counteract salt, but taste as you go.
I often reduce the corned beef's liquid by simmering uncovered for 3-4 minutes to intensify flavors. 🌶️
Crust Perfection
For a flaky crust, chill the dough for 30 minutes before rolling—this prevents shrinking. Use a rolling pin with a marble base (like OXO Good Grips) for even thickness.
Brush the bottom crust with 1 tbsp melted butter before adding filling to prevent sogginess. Seal edges with a fork for extra strength.
Mashed Potato Crown
Hot potatoes + warm milk = ultra-creamy topping. I use a potato ricer (not a masher) for silky texture. For extra richness, fold in 2 tbsp sour cream before spreading. The nutmeg is crucial—use freshly grated for maximum warmth. Spread evenly to ¼-inch thickness for even baking.
Baking Secrets
Pre-bake the bottom crust for 8 minutes at 375°F to prevent sogginess. Place a baking sheet under the pie dish to catch drips. For a restaurant-style finish, broil for 2 minutes at the end to crisp the topping. Let rest 20 minutes before slicing—this keeps the filling intact. ✨
Make-Ahead Magic
Assemble the pie (unbaked) up to 24 hours ahead, refrigerate, then bake straight from cold. For freezing, bake the filling only, then freeze assembled pie (unbaked) for 3 months. Thaw overnight in the fridge before baking. The crust will crisp beautifully after reheating.
Equipment Upgrades
Invest in a pie bird (like Wilton's) to prevent soggy tops during baking. A pie cooling rack keeps the bottom crust crisp. For even heat, use a glass pie dish—it browns better than metal. I swear by Pyrex for consistent results. 💡

Frequently asked questions
Can I use canned corned beef hash instead of shredded corned beef?
Yes, but with a few adjustments! Drain the hash well and chop it into ½-inch pieces for even cooking. You may need to add 1-2 tablespoons extra milk to the mashed potato crown since hash tends to be drier. The texture will be slightly chunkier but still delicious.
How do I make this pie without a pie crust?
For a crustless version, spread the corned beef filling in a 9-inch oven-safe skillet and top with the mashed potato mixture. Bake at 375°F for 30-35 minutes until golden and bubbly. Finish under the broiler for 2-3 minutes to crisp the top. Serve straight from the skillet for easy cleanup!
Why did my pie crust turn out soggy?
Soggy crusts usually happen when steam gets trapped. Always pre-bake the bottom crust for 8 minutes before adding filling, and cut vent slits in the top crust. For extra insurance, brush the bottom crust with 1 tablespoon melted butter before adding filling. Chill the assembled pie for 30 minutes before baking to help the crust set.
Can I use instant potatoes for the mashed potato topping?
Use 2 cups instant potatoes (like Idahoan) mixed with 1 cup warm milk and ¼ cup butter. Add ½ teaspoon salt and ¼ teaspoon nutmeg for seasoning. The texture will be slightly lighter but still creamy. This cuts prep time by 15 minutes while keeping the same great flavor.
What's the best way to reheat leftovers?
Slice the pie and reheat portions in a 350°F oven for 15-20 minutes until the topping is crispy. For microwave reheating, cover with a damp paper towel and heat in 30-second bursts on medium power. The oven method gives the best texture, but microwave works in a pinch. Leftovers keep well for 4-5 days in the fridge.
