Step-by-Step Instructions: How to Make Chicken Pot Pie Casserole from Scratch
1. Prep the Chicken and Veggies
You’ll want your chicken ready before anything else. Roast your own, use a rotisserie bird, or boil some breasts and shred them—it’s entirely your call. Just make sure it’s well-seasoned.
Next, chop the carrots, celery, and onion. Uniform pieces make for even cooking and better texture in every bite.
2. Create a Creamy, Savory Base Sauce
This is where the magic happens. Start by melting butter in a deep skillet. Add onions and celery and sauté until they soften and start to glisten.
Now, stir in your flour to make a roux. Don’t rush it—cook the flour just long enough to eliminate that raw flavor.
Slowly add the broth and milk, whisking constantly to avoid lumps. Let it simmer and thicken. Once it coats the back of a spoon, you’re golden.
Fold in the peas, carrots, and shredded chicken. Add your herbs and season to taste.
📝 Pro Tip: Let the filling cool slightly before assembling—it keeps the crust from getting soggy.
3. Assemble the Casserole
Preheat your oven to 375°F (190°C). Grease a 9×13 baking dish and pour in the warm filling.
Unroll your puff pastry or pie crust, and gently lay it over the top. Crimp the edges if you’re feeling fancy. Cut a few slits in the top to let steam escape.
Brush with egg wash if you want that gorgeous golden sheen.
4. Bake It to Perfection
Place your dish in the center rack and bake for 30–35 minutes. When the top is golden and the edges are bubbling, you’ll know it’s done.
Let it sit for about 10 minutes. It’s tempting to dive right in, but this short rest makes slicing and serving much easier.
Pro Tips for the Best Chicken Pot Pie Casserole
If you want your casserole to go from good to unforgettable, keep these tips in mind:

- Let the sauce cool before adding the crust—it keeps things crisp.
- Add mushrooms or garlic for even more umami.
- Egg wash = golden top. Always worth the extra step.
