Ingredients
For this easy corned beef potato pie, you’ll need:
- 2 (12-ounce) cans corned beef, chilled
- 2 1/2 pounds russet potatoes, peeled and cut into chunks
- 1 cup whole milk, plus more if needed
Because canned corned beef can already be quite salty, taste the mashed potatoes before adding additional salt.
How to Make Corned Beef Potato Pie
1. Prepare the Potatoes
Preheat the oven to 400°F (200°C). Place the chopped potatoes in a large pot and cover them with cold water. Bring to a boil and cook for about 12–15 minutes, or until the potatoes are tender when pierced with a fork.
2. Prepare the Corned Beef
While the potatoes are cooking, crumble the chilled canned corned beef into small pieces using a fork. Keeping the corned beef cold makes it easier to break apart.
3. Make the Mashed Potatoes
Drain the cooked potatoes well and return them to the warm pot. Add the milk and mash until smooth but sturdy enough to spread.
If the potatoes are too thick, add another tablespoon or two of milk until they reach a spreadable consistency.
4. Build the Pie
Lightly prepare a 9-inch glass pie dish and place it on a baking sheet.
Spread about half of the mashed potatoes across the bottom of the dish, gently pressing them toward the sides.
Scatter the crumbled corned beef evenly over the potatoes.
Cover the corned beef completely with the remaining mashed potatoes. Smooth the top with a spoon, then use a fork to create ridges across the surface. These ridges will become beautifully golden and crisp while baking.
5. Bake
Bake the pie for 30–35 minutes, until the top is golden brown and the edges are crisp.
For an even darker crust, place the pie on the upper rack during the final few minutes, watching carefully to prevent burning.
6. Rest and Serve
Allow the pie to rest for about 10 minutes before slicing. This gives the layers time to set, making it easier to serve neat portions.
Serve warm with green beans, peas, salad, dinner rolls, or your favorite simple vegetable side.
Variations
Although this recipe is designed around three main ingredients, there are several easy ways to change it.
Cheesy Corned Beef Pie: Add shredded cheddar to the mashed potatoes or sprinkle some over the top before baking.
Extra-Crispy Potato Topping: Brush a small amount of milk over the potatoes before baking to encourage additional browning.
Richer Flavor: Replace some of the milk with evaporated milk or a splash of cream.
Onion Flavor: Simmer a quartered onion with the potatoes, then remove it before mashing.
What to Serve With Corned Beef Potato Pie
This hearty pie pairs well with simple sides such as:
- Buttered peas
- Green beans
- Tossed green salad
- Roasted vegetables
- Dinner rolls
- Fresh bread
For a classic old-fashioned touch, serve individual slices with a little ketchup or mustard on the side.
How to Store Leftovers
Allow leftover corned beef potato pie to cool promptly, then cover and refrigerate it within 2 hours.
To reheat, place portions in a 350°F oven until heated thoroughly. The center should reach 165°F (74°C).
