This vegan chicken pot pie casserole is rich, creamy, and well-seasoned. It has the same hearty, comforting flavor as a traditional chicken pot pie, but without any of the meat or dairy. You can even make it gluten-free!

Chicken pot pies are one of the most comforting foods around. They’re warm, soothing, creamy, and hearty, with lots of familiar flavors. Unfortunately, they’re usually packed full of dairy and meat. So I decided to come up with a vegan recipe that hits all of the same flavors. And I decided to make it a casserole, which is a little easier than making individual pot pies, and much more convenient for serving a family. 

This vegan pot pie casserole, made with meatless chicken, carrots, and potatoes, is so filling. And it’s full of strong flavors from the garlic, thyme, and black pepper. This recipe will be a hit with anyone you serve it to, not just vegans! Plus, you can easily make it gluten-free as well.

How to Make Vegan Chicken Pot Pie Casserole

Here’s how to make this hearty and rich pot pie. 

  • Prep. Preheat the oven to 425F, and lightly grease a 2-quart casserole dish. 
  • Prepare the chicken. Follow the instructions on the package to cook the vegan chicken. 
  • Prepare the puff pastry. Place the puff pastry on a piece of parchment paper and roll it out until it’s a little bit larger than the casserole dish. Place the casserole dish upside-down on the puff pastry and trim the pastry so that it fits the dish. Cut a few holes in the center of the puff pastry for ventilation.

  • Freeze the puff pastry. Carefully lift up the parchment paper with the puff pastry, and place it on a baking sheet, then put the baking sheet in the freezer while you continue with the recipe. 
  • Cook the veggies. Heat a dutch oven over medium heat and add the oil. Then add the carrots, onion, celery, and potatoes, and cook, stirring occasionally, until the onions and celery are tender. This should take about 10 minutes. 
  • Add the flour and seasonings. Add the flour, thyme, garlic, salt, and pepper to the dutch oven and cook for 2 more minutes, while stirring.

Tips for Success

Here are some of my favorite tricks and tips for making this hearty casserole.

  • Make your own broth. If you want to really take this vegan chicken pot pie casserole to the next level, you can do so by making your own vegetable broth. Homemade veggie broth is a lot more flavorful than what you’ll find in the store, so making your own broth really adds to the complexity of this dish. Here’s my recipe for a vegetable stock that uses veggie scraps.
  • Make consistent cuts. When cutting the vegetables for this recipe, try to cut them all to similar sizes. That way the veggies will cook at the same speed, and you won’t have a pot pie that has some overcooked or undercooked vegetables. 
  • Add whatever veggies you want. Potatoes, carrots, onion, celery, and peas are the standard vegetables for chicken pot pie, but feel free to clean out your fridge by using up whatever spare veggies you have around the house. You can put almost any veggies in this dish and they’ll taste great!
