Irish Prime Rib Pie: A Celebration of Comfort and Tradition

Every year after our family’s traditional Christmas prime rib dinner, the scent of savory herbs and roasted beef seemed to linger in the air, a comforting reminder of shared laughter and warm company. But the best part was always the day after: Irish Prime Rib Pie. My grandmother, with flour dusting her apron and a twinkle in her eye, would transform the leftover roast into this masterpiece. The flaky, golden crust, the tender beef melding with sweet carrots and potatoes in a rich gravy, was pure magic—a second act even better than the original.

Ingredients

1 pie crust
2 medium potatoes, cut in 1-inch chunks
2 medium carrots, halved, quartered lengthwise
4 tablespoons unsalted butter
8 small white onions (frozen or from a jar)
½ teaspoon sugar
¼ cup white wine
3 ½ tablespoons all-purpose flour
1 cup hot beef stock or 1 cup broth
1 cup heavy cream
1 ½ lbs leftover prime rib roast beef, cut into 1-inch chunks
0.5 (5 ounce) package frozen peas, defrosted and drained
1 pinch cayenne pepper
⅛ teaspoon ground allspice
Salt & freshly ground black pepper
1 tablespoon chopped chives
1 tablespoon chopped flat leaf parsley
1 egg yolk, beaten with 1 t. water

Equipment Needed

Large saucepan
Small skillet
2-quart casserole dish or deep-dish pie pan
Rolling pin
Whisk

Instructions

Preheat your oven to 450 degrees Fahrenheit.
Begin by preparing the vegetables. In a large pot, combine the potatoes and carrots in boiling salted water. Cook until they are just tender. Drain the potatoes and carrots well and set them aside.
While the root vegetables are cooking, turn your attention to the onions. In a small skillet, melt 1 tablespoon of the unsalted butter over medium heat. Sauté the white onions until they are lightly browned.
Reduce the heat to low. Sprinkle the onions with the sugar, and toss lightly to coat them evenly.
Pour in the white wine and cook until almost all the liquid has been absorbed by the onions. Remove the skillet from the heat and set the onions aside.
Now, it’s time to create the gravy base. In a large saucepan, melt the remaining 3 tablespoons of unsalted butter over low heat.
Add the all-purpose flour to the melted butter, creating a roux. Whisk the roux constantly for 3 minutes. This crucial step ensures a smooth, lump-free gravy.
Gradually add the hot beef stock to the roux, whisking constantly to prevent any lumps from forming. The mixture should thicken considerably as you whisk.
Slightly raise the heat under the saucepan. Pour in the heavy cream, stirring constantly to incorporate it fully into the gravy.
Reduce the heat to low and continue to cook and stir for 1 minute longer, allowing the flavors to meld together.
Add the cooked potatoes, carrots, sautéed onions, leftover prime rib roast beef, defrosted peas, cayenne pepper, and ground allspice to the saucepan.
Season the mixture generously with salt and freshly ground black pepper to taste. Mix all the ingredients well, ensuring the beef and vegetables are evenly coated in the creamy gravy. Remove the saucepan from the heat.
Spoon the beef and vegetable mixture into a 2-quart casserole dish or a deep-dish pie pan.
Sprinkle the top of the mixture with the chopped chives and chopped flat leaf parsley.
On a lightly floured surface, roll out the pie dough. Carefully place the rolled-out dough over the top of the casserole dish, covering the filling completely.
Build up the edges of the pie dough high and pinch them into the rim of the dish to create a decorative and secure seal. This will help prevent the filling from bubbling over during baking.
Cut a slit in the top of the pie crust to allow steam to escape during baking. This will help prevent the crust from becoming soggy.
In a small bowl, whisk together the egg yolk and 1 teaspoon of water. Brush this egg wash evenly over the entire surface of the pie crust. This will give the crust a beautiful golden-brown color and a glossy sheen.
Bake the pie in the preheated 450-degree Fahrenheit oven for 10 minutes.
After 10 minutes, reduce the oven temperature to 375 degrees Fahrenheit and bake for an additional 20 minutes, or until the crust is golden brown and the filling is bubbling.
Remove the Irish Prime Rib Pie from the oven and let it stand for 5 minutes before serving. This allows the filling to set slightly and makes it easier to slice.

Expert Tips & Tricks

Make-Ahead Gravy: The gravy base (steps 6-10) can be made a day ahead and stored in the refrigerator. This saves time on the day you’re assembling the pie.
Beef Enhancement: A splash of Worcestershire sauce or beef bouillon powder to the gravy can amplify the beefy flavor.
Crust Perfection: For an extra flaky crust, use cold butter or shortening when making your own or purchase a high-quality store-bought crust. Docking the crust (poking holes with a fork) before blind baking can also help prevent it from puffing up too much.

Serving & Storage Suggestions

Serve the Irish Prime Rib Pie warm, straight from the oven, with a dollop of sour cream or a sprinkle of fresh parsley for garnish. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, cover the pie with foil and bake at 350 degrees Fahrenheit until warmed through, or microwave individual slices. Freezing is not recommended as it can affect the texture of the crust.
