Chicken pot pie is one of my favorite dishes, but it can be such a chore dealing with both the top and bottom crusts. This chicken pot pie casserole makes my life so much easier! This crazy good chicken casserole is loaded with carrots, peas, and chicken, and topped with a flakey pie crust, making it the ultimate easy comfort food! Prep only takes 15 minutes, and it’s so unfussy!

This casserole is loaded with the tastiest sauce, chunky chicken, peas, carrots, and more, and topped with a beautiful lattice pie crust. I love how homey, delicious, fun, and comforting it is. It has all the flavor of my favorite classic chicken pot pie, but it’s there for me when I need something less fussy!

What’s in this Chicken Pot Pie Casserole Recipe?

• Pie Crust: For this recipe, I love that I only need one pie crust to place on top of the pie– so easy!
• Butter + Oil: Olive oil helps the veggies cook without burning, while butter infuses them with a rich flavor.
• Mirepoix: Carrots, celery, and onion create a flavorful, vegetal base for this dish.
• Garlic: Adds an earthy flavor.
• Chicken: Pot pie is the perfect recipe to use up leftover cooked chicken. I cubed mine, but shredded chicken also works well!
• Mushrooms: Add a rich umami flavor.
• Peas: Add a pop of color and sweetness.
• All-Purpose Flour: Thickens the gravy.
• Chicken Broth: Combines with the fat and drippings to create a rich gravy.
• White Wine: Adds a touch of acidity and freshness. You can use a splash of vinegar and more chicken broth if you prefer.
• Heavy Cream: Makes this pot pie thick and creamy. You can use half-and-half to lighten it up a bit.
• Spices: Kosher salt, black pepper, thyme, and basil enhance the flavors of this dish.
• Egg: Combines with water to create an egg wash that gives the crust a rich golden brown color.

Tips for Success

• For a gluten-free pie, use a gluten-free pie crust and gluten-free 1:1 all-purpose flour.
• For a dairy-free pie, use dairy-free butter and coconut cream or soy-based heavy whipping cream.
• If you like your filling a bit thicker, continue simmering until it thickens to the desired consistency.
• Try to keep the crust relatively taut over the baking pan so that it doesn’t touch the filling. If it is sitting directly on the filling, it may take longer to bake due to the extra moisture.
• If you notice that the pot pie crust is browning too quickly, loosely cover the pot pie with foil halfway through baking.

How to Store and Reheat

Store: Store leftover chicken pot pie casserole in an airtight container in the refrigerator for up to 3 days. Reheat in a 375°F oven for 25-30 minutes, or until warmed through.

Freeze: You can freeze chicken pot pie casserole both before and after baking. Just be sure to do so in a non-glass baking dish to prevent it from shattering. Tightly wrap the casserole in 2 layers of plastic wrap and 1 layer of aluminum foil and freeze for up to 2 months.

Reheat: To reheat an already-baked frozen pie, place it in a 375°F oven for 30-35 minutes. To bake from frozen, bake in a preheated oven with the foil on for 30 minutes, then remove the foil and continue to bake for 45-50 minutes, until golden brown and 165°F internally.

Serving Suggestions

This chicken pot piecasserole is a meal all by itself. But because this casserole doesn’t have a second crust, you could serve it over a bed of mashed potatoes, rice, or cauliflower. A fresh green salad or some roasted vegetables on the side would also be delish! For something a little lighter, consider some coleslaw.
