How to Make Gluten Free Chicken Pot Pie Casserole

1. Preheat your oven to 425°F and ensure your baking dish is ready to go.
2. Combine gluten-free flour and salt in a mixing bowl, then cut in cold butter until the texture resembles coarse crumbs.
3. Slowly stir in the cold milk until a dough forms. Divide the dough in half, wrap one portion, and refrigerate.
4. Roll out the remaining dough and press it into the bottom and sides of your casserole dish, then poke holes with a fork and prebake for 5-7 minutes.
5. Start the filling by melting butter in a large saucepan. Add onions, carrots, and celery, cooking for about 6 minutes until softened.
6. Stir in mushrooms, cooking for another 7-10 minutes, then add peas, salt, and pepper.
7. Sprinkle potato starch and gluten-free flour over the veggies, stir to coat, and cook for a minute.
8. Pour in milk and broth, stirring constantly until the mixture thickens. Add cooked chicken and simmer 2-3 minutes before removing from heat.
9. Pour the filling into the pre-baked crust. Roll out the refrigerated dough and either make shapes with a cookie cutter or cover the filling fully with the rolled dough.
10. Bake the casserole for 35 minutes until the crust is golden brown. Allow to cool for 10 minutes before serving.

• For easy cleanup, line your work surface with parchment paper while rolling the dough.
• Make it ahead! The filling can be prepped and stored in the fridge up to two days in advance.
• Reheat leftovers in the oven instead of the microwave to maintain that crusty texture.
