What Ingredients You Will Need

This recipe uses simple, wholesome ingredients that you likely already have in your kitchen. Here’s everything you’ll need:

• For the filling:
• 2 cups cooked chicken breast, shredded or diced (rotisserie chicken works wonderfully)
• 2 cups frozen mixed vegetables (carrots, peas, corn, and green beans)
• 1/3 cup unsalted butter
• 1/3 cup all-purpose flour
• 2 cups chicken broth (low-sodium preferred)
• 1 cup milk (whole milk or a non-dairy alternative like oat milk works too)
• 1 teaspoon garlic powder
• 1/2 teaspoon onion powder
• Salt and pepper, to taste
• For the crust:
• 1 package refrigerated pie crust (you can use homemade if you prefer)
• 1 egg, beaten (for brushing the crust)

If you’re feeling adventurous, you can swap out the frozen veggies for fresh ones, or use leftover turkey instead of chicken. Don’t have pie crust? Puff pastry works beautifully as a substitute. This recipe is all about flexibility!

Equipment Needed

• Baking dish (9×13-inch works well)
• Large skillet or saucepan
• Whisk (for the roux)
• Mixing spoon
• Rolling pin (if using homemade crust)
• Basting brush (for the egg wash)

If you don’t have a rolling pin, a clean wine bottle works just as well to roll out the crust. And if you don’t own a basting brush, you can use a piece of paper towel or your fingers to apply the egg wash—just be sure to wash up afterward!

Preparation Method

1. Preheat your oven: Set your oven to 375°F (190°C) and grease your baking dish lightly with butter or non-stick spray.
2. Cook the filling: In a large skillet, melt the butter over medium heat. Once melted, whisk in the flour and cook for 1-2 minutes to create a roux.
3. Add liquids: Gradually pour in the chicken broth and milk, whisking continuously to avoid lumps. Cook for 5-7 minutes until the mixture thickens.
4. Season: Stir in garlic powder, onion powder, salt, and pepper. Taste and adjust seasoning as needed.
5. Add chicken and vegetables: Fold in the shredded chicken and frozen mixed vegetables. Cook for another 2-3 minutes to combine flavors.
6. Assemble the casserole: Pour the creamy filling into the greased baking dish, spreading it evenly.
7. Prepare the crust: Roll out the pie crust (if needed) and place it on top of the filling. Tuck the edges of the crust into the dish to seal.
8. Brush with egg wash: Lightly brush the beaten egg over the crust for a golden, shiny finish.
9. Bake: Place the casserole in the oven and bake for 30-35 minutes, or until the crust is golden brown and the filling is bubbly.
10. Cool slightly: Allow the casserole to cool for 5-10 minutes before serving—this helps the filling set.

The smell of this casserole baking is enough to make your mouth water. Keep an eye on the crust as it nears the end of baking—it should be golden and slightly crisp around the edges.

Cooking Tips & Techniques

Here’s what I’ve learned from making this casserole more times than I can count:

• Use cold butter for the roux to prevent it from burning.
• If your filling looks too thick, add a splash of broth or milk to loosen it up.
• For an extra-crispy crust, sprinkle a pinch of sea salt on top before baking.
• Don’t skip the egg wash—it makes the crust look so much more inviting!
• If you’re short on time, you can prep the filling ahead of time and just assemble the casserole right before baking.

One time I forgot to let the filling cool slightly before topping it with the crust, and the dough turned soggy. Lesson learned! Be patient—those few extra minutes can make a big difference.

Variations & Adaptations

This chicken pot pie casserole is incredibly versatile. Here are a few ways you can make it your own:

• Gluten-Free: Swap the all-purpose flour for a gluten-free alternative, and use a gluten-free pie crust.
• Dairy-Free: Replace the milk with almond or oat milk, and use vegan butter in the roux.
• Vegetarian: Skip the chicken and add more vegetables like mushrooms, zucchini, or sweet potatoes. Use vegetable broth instead of chicken broth.
• Seasonal Twist: In the fall, try adding diced butternut squash or parsnips. During summer, fresh corn and green beans are perfect.

One time I added a sprinkle of shredded cheddar cheese between the filling and the crust—it was a total hit with my family! Feel free to experiment with your favorite flavors.

Serving & Storage Suggestions

Serve this chicken pot pie casserole warm, straight out of the oven. Pair it with a crisp green salad or roasted vegetables for a complete meal. For a comforting touch, you could even serve it alongside a bowl of creamy mashed potatoes.

If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. To reheat, cover and warm in a 350°F (175°C) oven until heated through, or microwave individual portions. This casserole also freezes well—just make sure to wrap it tightly to prevent freezer burn. When reheating from frozen, bake covered at 375°F (190°C) until hot.
