Like clockwork, I get a deep craving for pot pie around this time of year. The comforting dinner was a staple of my childhood, and I’ve been making it during cold winter months ever since.

As much as I love a classic chicken pot pie, it’s really the rich gravy and buttery pie crust that draws me in — I’ve never felt the chicken is essential. This vegetarian version is just as homey and satisfying, and is an easy way to transform a traditionally meaty dish into a plant-based one. Expect it to become a new favorite — whether you’re vegetarian or not.

Why You’ll Love It

It’s hearty and comforting. Tender sweet potatoes, meaty mushrooms, and wilted kale, all swimming in a rich and creamy gravy.
The crust is flaky and buttery. The mix of hearty vegetables ensures each bite will warm you up, while the flaky puff pastry crust will keep you going in for another bite.

Key Ingredients in Vegetarian Pot Pie

Puff pastry: Store-bought frozen puff pastry is convenient and easy. Look for an all-butter puff pastry for the best flavor.
Vegetables: We use a hearty mix of vegetables here – sweet potatoes, cremini mushrooms, and kale. Opting for baby kale here trims down prep work — all you have to do is toss it into the skillet rather than worrying about stripping the leaves and chopping them.
All-purpose flour: Thicken the gravy with a bit of flour.
Vegetable broth: Use low-sodium vegetable broth to control the amount of salt in the pot pie.
Milk: You can use either whole milk or 2% milk for the creamy gravy.

How to Make Vegetarian Pot Pie

Cook the sweet potatoes. Sauté the onion until softened. Add the sweet potatoes and cook, stirring occasionally, until the sweet potatoes are just tender. Transfer the mixture to a plate or bowl.
Cook the mushrooms. Add the mushrooms and cook, stirring occasionally, until just tender. Add the garlic and thyme and sauté until fragrant.
Make the gravy. Sprinkle in the flour and whisk until the flour dissolves. While whisking constantly, slowly add the low-sodium vegetable broth and whisk until smooth. Bring to a simmer and stir with a wooden spoon until thickened.
Finish the filling. Remove from heat. Stir in the baby kale a few handfuls at a time until just wilted. Stir in the milk. Return the sweet potato mixture to the skillet and stir to combine.
Bake. Unfold the puff pastry and place it over the filling, tucking the excess pastry inside the pan. Use a sharp knife to cut slits in the crust as vents. Bake until the crust is golden-brown.

Helpful Swaps

Baby spinach: You could easily swap in baby spinach for the baby kale, if your prefer.
10-inch skillet: The pot pie can also be prepared in a 10-inch cast iron or other oven-safe high-sided skillet but the gravy may bubble over in the oven. To prevent oven messes, bake the 10-inch skillet on a parchment paper-lined baking sheet.

Storage Tips

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.

Prep time 10 minutes to 15 minutes

Cook time 50 minutes to 55 minutes

Serves 4

Ingredients

1 sheet frozen puff pastry (from a 17-ounce box), thawed
1 small yellow onion, finely chopped
1 pound sweet potatoes (about 2 medium), peeled and cut into 1/2-inch cubes
1 pound cremini mushrooms, quartered
2 cloves garlic, minced
1 teaspoon fresh thyme leaves
5 ounces baby kale (about 5 packed cups)
3 tablespoons olive oil, divided
1 teaspoon kosher salt, divided
1/2 teaspoon freshly ground black pepper, divided
3 tablespoons all-purpose flour
2 cups low-sodium vegetable broth
1/2 cup whole or 2% milk

Instructions

Arrange a rack in the middle of the oven and heat the oven to 400°F.
Heat 2 tablespoons of the olive oil in a 12-inch cast-iron or oven-safe straight-sided skillet over medium heat until shimmering. Add 1 finely chopped yellow onion and sauté until softened and translucent, 3 to 4 minutes. Add 1 pound peeled and cut sweet potatoes, 1/2 teaspoon of the kosher salt, and 1/4 teaspoon of the black pepper, and cook, stirring occasionally, until the sweet potatoes are just tender, about 10 minutes. Transfer the mixture to a plate or bowl.
Add the remaining 1 tablespoon of olive oil to the skillet. Add 1 pound quartered cremini mushrooms, remaining 1/2 teaspoon kosher salt, and remaining 1/4 teaspoon black pepper. Cook, stirring occasionally, until just tender, 5 to 7 minutes. Add 2 minced garlic cloves and 1 teaspoon fresh thyme leaves and sauté until fragrant, about 1 minute more.
Sprinkle in 3 tablespoons all-purpose flour and whisk until the flour dissolves. While whisking constantly, slowly add 2 cups low-sodium vegetable broth and whisk until smooth. Bring to a simmer and stir with a wooden spoon until thickened, 8 to 10 minutes.
Remove from heat. Stir in 5 ounces baby kale (about 5 packed cups) a few handfuls at a time until just wilted, 1 to 2 minutes. Stir in 1/2 cup whole or 2% milk. Return the sweet potato mixture to the skillet and stir to combine.
Unfold the puff pastry and place it over the filling, tucking the excess pastry inside the pan. Use a sharp knife to cut 4 (1-inch) slits in the crust as vents. Bake until the crust is golden-brown, about 20 minutes. Let cool 10 minutes before serving.
