How to Make Chicken Pot Pie Casserole
-
Preheat Oven: Begin by preheating your oven to 375°F. Make sure to spray a 2-quart casserole dish with nonstick spray and set it aside for later use.
-
Prepare Pie Crust: Let the pie crust sit at room temperature for about 15-20 minutes. This will make it easier to roll out and shape while keeping it pliable.
-
Heat Butter and Oil: In a large skillet over medium-high heat, melt the unsalted butter with olive oil until it shimmers. This combination adds flavor and prevents the butter from burning.
-
Sauté Veggies: Add the diced carrots and celery to the skillet. Cook them for 3 minutes, stirring occasionally, until they start to soften. Their vibrant colors will brighten your kitchen!
-
Cook Onions: Toss in the minced onions and continue to sauté until they become translucent, about 3-4 minutes. The aroma at this point is irresistible!
-
Add Garlic: Stir in the minced garlic, cooking for an additional 30 seconds until fragrant. This step really enhances the dish’s flavor profile.
-
Incorporate Chicken and Mushrooms: Add the cubed, cooked chicken, sliced mushrooms, and frozen peas to the mixture. Cook for 1 minute just to warm everything through.
-
Thicken Sauce: Sprinkle the flour over the mixture and cook, stirring continuously for about 3 minutes. This helps to create the base for your creamy filling.
-
Deglaze the Pan: Pour in the chicken stock while scraping the bottom of the pan to release all those flavorful bits. This adds depth to your sauce.
-
Add Cream and Wine: Stir in the white wine and heavy cream, mixing well. Allow this to cook for a few minutes until the mixture thickens to a creamy, stew-like consistency.
-
Season to Taste: Season your filling with salt, pepper, thyme, and basil. Stir everything together, letting it simmer for a few more minutes until all the flavors meld beautifully.
-
Assemble Casserole: Pour the chicken stew mixture into the prepared casserole dish, spreading it out evenly.
-
Prepare Pie Crust: Roll the pie crust to about ¼ inch thickness, then cut it into 1-inch strips to create a lovely lattice top, or simply drape it over the filling and crimp the edges.
-
Egg Wash: Mix the egg with a splash of water, then brush it over the crust. This gives it that gorgeous golden hue when baked.
-
Bake to Perfection: Place the casserole on the center rack of the oven and bake for 35-45 minutes, or until the crust is golden brown and crisp.
Optional: Serve with a sprinkle of fresh herbs for added flavor and color.
