About this Leftover Prime Rib Recipe

Like most households at holiday time, ours is very busy. Between kids coming home from college and family visiting from other states, a lot is going on, especially in the kitchen.

To say there was no food shortage would be a bit of an understatement. This is one reason we make so many delicious leftover recipes!

These were the circumstances we faced following our big Prime Rib dinner on Christmas day. (As I found out, If you don’t have leftover prime rib, you can make this delicious pot pie using leftover smoked brisket.) This leftover prime rib recipe is actually the perfect use for any leftover roast beef.

If you want some leftover steak recipes, this flakey pot pie will be your new best friend.

We also had a package of leftover phyllo dough from one of last week’s television segments that we shot in Green Bay. How could I use both of these tasty foods together? It didn’t take long to come up with a solution and to the delight of our family, this leftover prime rib recipe was born!

Christmas is a special time for many families. For us, our oldest was home from his freshman year of college, and we were all together once again for a few days.

Our guys love this special cut of meat, and although it’s not something we make often, this seemed like an appropriate occasion. When I do make it, I usually have enough for a small army (we do have six boys, after all.)

All I can say to my accusers is that I never hear any complaints about this leftover prime rib recipe!

A pan of meat and a phyllo dough.

What’s in this Leftover Prime Rib Recipe:

  1. Phyllo Dough: Wrapped around the filling to create a flaky, golden crust for the pot pie.
  2. Leftover Prime Rib: Diced into hearty chunks, it’s the savory star, bringing richness and depth to the pie.
  3. Butter and Olive Oil: Used to sauté the vegetables, adding flavor and ensuring a tender filling.
  4. Celery: Chopped and sautéed, it contributes a mild, slightly peppery crunch to the mix.
  5. Carrot: Sliced into bite-sized pieces, it adds sweetness and vibrant color to the hearty filling.
  6. Onion: Diced and caramelized, it forms the aromatic foundation of the pie’s savory flavor.
  7. Potato: Cubed and cooked till tender, potatoes offer substance and soak up the surrounding flavors.
  8. Peas: Sprinkled in for sweetness, a pop of green peas brightens the hearty mixture.
  9. Corn: Added for its juicy kernels, corn brings a mild sweetness and textural variety to the filling.
  10. Red Wine: Deglazes the pan, adding a robust depth of flavor that complements the prime rib.
  11. Worcestershire Sauce: A dash enhances the umami and complexity of the pie’s gravy.
  12. Dijon Mustard: A spoonful stirred in for a tangy kick that balances out the meat’s richness.
  13. Bay Leaves: Tucked in for their aromatic and subtly bitter notes, they infuse the pie with herbal undertones.
  14. Seasoning: A careful blend of herbs and spices is chosen to highlight and harmonize all the flavors of this leftover prime rib recipe.

Per the popular demand of our troop of boys, our (Almost) World Famous Mac ‘n Cheese was also on the menu. When served as a side dish, it goes great with just about anything!

May I just say that both featured entrées came out quite well, and maybe due to the quantity of food on our table, there were plenty of leftovers.

That’s how we came up with this leftover prime rib recipe!

Some pot pie on plate.
This simple potpie is the perfect way to use your leftover prime rib.

It turns out that phyllo and leftover prime rib go very well together. However, how can anything not go well with a mouthwatering prime rib – let alone sheets of buttery and flaky phyllo dough?

Together, with this Leftover Roast Beef Pot Pie, the two came together beautifully.

It wasn’t just the meat we used to make this leftover prime rib recipe. The carrots and celery that we roasted with the original entrée went into the mirepoix.

Similarly, the potatoes that roasted with the leftover beef were also added to the mix.

With a little more seasoning and some time on the stove, followed by another trip to the oven, this leftover roast beef recipe proved to be a great use of leftovers.

It seemed to me that the guys loved this leftover creation just as much as the original dish, giving us good reason to call this meal a true double hitter. 

Recipe Tips

When making this leftover prime rib recipe, keep these tips in mind for the best results:

  1. Sauté to Perfection: Take the time to properly sauté the mirepoix (onion, carrots, and celery) until the onions are soft and translucent. This not only builds the foundational flavor for the pie but also ensures that the vegetables are cooked evenly, contributing to the overall texture and taste of the dish.
  2. Layering Phyllo Dough: Handle the phyllo dough carefully, brushing each layer with melted butter before adding the next. This will help achieve a golden, flaky crust that is a hallmark of a great pot pie. Ensure the edges of the phyllo are properly tucked and molded to the pie plate to prevent burning or uneven cooking.
  3. Balancing Liquid Ingredients: When adding the flour, do so gradually to reach the desired consistency of your sauce/gravy without making it too thick or too runny. The reduction of wine and the simmering of broth and milk are crucial steps to concentrate flavors and create a rich, savory filling. Monitor the thickness of the gravy as it simmers, adjusting as necessary to ensure it’s neither too thin nor too thick for a luscious, enveloping texture in every bite.

  1. Can I freeze this? so I can save some for my husband who’s out of town and wished he could try this delicious concoction 🤤

    1. Hello Renee and thanks for this great question. Yes, you can freeze the Prime Rib Pot Pie. To do so effectively, ensure the pot pie is completely cooled after baking. Wrap the pot pie securely in plastic wrap or aluminum foil, then place it in a freezer-safe container or freezer bag. When you’re ready to serve it, you can thaw the pot pie in the refrigerator overnight and then reheat it in the oven at 350 degrees F until it’s warmed through. This method will help maintain the pie’s quality and taste, making it a delicious meal for your husband to enjoy upon his return. Remember to monitor the reheating process closely to prevent the phyllo dough from burning.

  2. 5 stars
    Totally worth the “effort” and time. Lots of prep, so not hard and delicious for all that ate….husband had three servings.

  3. 4 stars
    I made this for supper tonight and it was delicious! Even the kids loved it which was surprising since they barely touched the prime rib dinner that preceded it.
    While this is true what I really wanted to say was it took me 35 to 40 minutes to assemble the pie and another 35 minute cook time. Knowing this I would still make again if the stars aligned and I somehow had all the ingredients in the house at the same time.
