🔪 How To Make Leftover Prime Rib Pot Pie

By using leftover prime rib, the prep time is cut down a lot! Take out a saucepan, silicone whisk, mixing bowl, and a 9-inch pie pan to begin!

This pot pie recipe will yield about 4 hearty servings. You can easily double this recipe if you need to serve a larger crowd.

  1. Prep. Preheat your oven to 350°F (175°C) and move your baking rack down to the second rack from the bottom.
  2. Saute onion. In a large skillet over medium heat, melt the 1 tablespoon of butter and saute the 1 cup of yellow onion until tender. Add 1 teaspoon salt, 1 teaspoon pepper, and ½ teaspoon garlic powder. Stir to combine.
  3. Add ingredients. In a small mixing bowl or your liquid measuring cup, dissolve the 3 tablespoons of cornstarch into the 2 cups of beef broth. Pour the mixture into the skillet with onions and add 1 teaspoon of Worcestershire sauce, 2 cups of frozen vegetables, and 1 pound of leftover prime rib roast meat, and then mix until smooth.
  4. Simmer. Bring the gravy with vegetables and beef to a simmer, then remove from heat and allow to thicken and cool slightly before transferring it into your pie crust.

Fill Pot Pie And Bake

  1. Fill the pie crust. Place the butter pie crust into your 9-in pie pan and poke holes with a fork throughout the bottom of the crust. Pour the pot pie filling into the crust and gently smooth it into one layer.
  2. Bake pot pie. Bake the pot pie on the lower rack at 350°F (175°C) for 15 minutes. Take the pot pie out and add 2 cups of mashed potatoes on top in a smooth layer. Place the pie back into the oven and bake for another 12-15 minutes.
  3. Cool and serve. Once the pie is done, take it out of the oven and allow it to cool for 5-10 minutes before serving.

Prime rib pot pie is a tasty main course meal on its own. However, you can't go wrong serving up some buttery rolls to soak up any extra gravy! Also, anything you can serve with a chicken pot pie would be great with this pot pie too! Enjoy!

💭 Angela's Tips & Recipe Notes

  • 2 cups of frozen vegetables weigh around 12 ounces and 3 cups of cooked prime rib will be around 1 pound.
  • You could easily swap the frozen veggie mix out for your favorite variety of frozen vegetables, like frozen peas and carrots, or frozen corn.
  • Baking pot pies on a lower shelf as suggested is what cooks the bottom crust!

🥡 Storing & Reheating

Place your leftover prime rib pot pie in an airtight container or wrap it tightly in foil and refrigerate it for up to 3 days.

Baked or unbaked pot pies can be frozen for up to 3 months. For long-term storage, you should flash freeze the pie on a baking sheet until fully frozen, then wrap it tightly in heavy-duty aluminum foil.

Reheating Leftover Prime Rib Pot Pie

Thaw the pot pie in the fridge overnight, then cover it with foil. Bake at 350 (175°C) for 15-25 minutes or until heated through. You can also microwave individual slices.

❓ Recipe FAQs

Can I Make Prime Rib Pot Pie Without Mashed Potatoes?

Yes! You can use a double-crust pie crust or top off your pot pie with Pillsbury Grands Biscuits. Also, some crescent rolls would be great too! Any way you pick, this pot pie will be delicious no matter what!

Can I Make Prime Rib Pot Pie In Advance?

Absolutely! You can make the filling up to 24 hours in advance from when you want to bake the pot pie. You may need to add up to 5-10 more minutes to the cooking time since the filling will be cold. You can also assemble the whole pot pie and freeze it for up to 3 months. Make sure to thaw the pie in the fridge overnight before baking.

Does Prime Rib Pot Pie Have A Top Crust?

This one does not, instead, it has a layer of mashed potatoes on top! So if you have a prime rib holiday dinner with mashed potatoes, this is the ultimate recipe to make the day after!
