Root Vegetable Skillet Pot Pie

This rustic take on a pot pie combines the classic fall flavors of carrots, sweet potatoes, rosemary, and sage in a creamy sauce that is rich and bold flavored, even without chicken stock. Enjoy this pot pie as a vegetarian holiday entree or a hearty side dish to a meat-centered meal.

All-in-One Skillet Pot Pie

This pot pie is prepped on the stove, baked in the oven, and served directly in the skillet—which saves time doing dishes! For those looking to save time upfront, a pre-made pie crust works as well as a freshly prepared one. If it cools before everyone comes to the table, you can pop it directly back into the oven to keep it warm until everyone is ready.

While it isn’t the fastest recipe, its presentation and taste stand up to a casual family dinner or an elegant meal.


If you find working with a traditional roux stressful, you’ll be happy to know that this recipe breaks down the process into a more foolproof one: Just add butter to the empty pan, sauté the vegetables, sprinkle the flour over the vegetables, then whisk in the liquid. Simmer until thickened.

When the pot pie goes in the oven, it will bake just long enough to cook the crust on top, and the filling won’t thicken much further.

The less time you spend on it the better—fork tines pressed all around, fingertip patterns, and other normally-great decor touches should be avoided, as they will melt the crust further.

  • If you make the crust yourself, this recipe is an excellent choice, because there will be no leftover crust. You do not need an egg wash on top, but feel free to use one for extra shine if preferred.
  • Keep the crust refrigerated until five minutes before rolling it out.
  • Cast iron pans retain heat, so it’s best to let the cooked filling sit for about 10 minutes before placing the crust over the skillet.
  • Make sure the crust reaches the edges of the pan, otherwise the filling will seep out. It can overlap the pan edges to the outside or reach just to the inner edge; either works fine.
  • Once the crust is placed on the skillet, you should make at least two one-inch vent lines with a sharp knife for steam to escape.


When it comes to flavor, rosemary and sage were chosen for their fall, holiday feel in this pot pie. Use either fresh or dried herbs; using one fresh and one dried is our suggestion, so you don’t have to have two types of fresh herbs on hand at once.

To substitute fresh or dried herbs or vice versa: Half tablespoon of fresh for one half teaspoon of dried.

If rosemary and sage aren’t your favorite flavors, you can also use:

  • Thyme
  • Italian herb blend
  • Dried dill

This pie is easy to adapt to your personal taste, but I do recommend sticking to mostly root vegetables here, because they all have similar cook times. If you swap in a green vegetables like broccoli or zucchini, they will overcook.

A half to three quarter-inch dice for all root vegetables will ensure even cooking, and since this is a rustic dish, there is no need for perfect cubes.

As far as root vegetables go, the underground world of tubers is at your disposal! Keep it simple with our selection of sweet potatoes, carrots, and potatoes, or make a colorful exchange with beets. You could also use parsnips, turnips, or rutabagas, if available.

Whatever combo you choose, stick to only one or two sweet root veggies (beets, sweet potatoes or yams, parsnips) with at least one savory (potatoes, rutabaga, turnip), to equal a total of four cups. Even though white sweet potatoes are slightly firmer than yellow, both work equally well here.

Peas are added for green color and a customary pot pie flavor; they can be omitted or swapped for lima beans, should you have friends or family who enjoy that embattled veggie.

No Cast Iron Skillet? No Problem

The fun of this dish will not be lost if you can’t cook and serve it all in one vessel! If you don’t have a cast iron skillet, cook the filling on the stove, then pour it into a deep dish pie plate, top with the crust, and bake that way. We used a 10-inch cast iron pan, so a 10-inch deep dish pie plate is ideal. If you don’t have a pie plate, cooking in a shallow 9×11-inch casserole pan will work.

This dish reheats well and can be made a day ahead, then popped back into the oven at 350°F for 25-30 minutes to reheat. Note that you do not want to keep it in the cast iron pan for more than two days, or you’ll risk the vegetables turning grey from the pan.

It also freezes nicely. Freeze individual portions or the entire pie in Tupperware containers, not the cast iron pan itself. While the pie crust may soften slightly, reheating in the oven instead of the microwave will help it re-crisp.
