Prepare the Creamy Filling
- Preheat your oven to 400°F (200°C).
- In a large skillet or Dutch oven, melt the butter over medium heat. Add the chopped onion and sauté until it becomes fragrant and translucent, about 5-7 minutes.
- Sprinkle the flour over the onions. Whisk continuously for about one minute to cook out the raw flour taste. This creates your roux, the base for a smooth, lump-free gravy.
- Slowly pour in the chicken broth while whisking constantly. Add the salt and pepper, then bring the mixture to a boil. Watch as it thickens beautifully!
- Reduce the heat and stir in the heavy cream, frozen mixed vegetables, and your pre-cooked chicken. If your frozen veggies have a lot of ice crystals, give them a quick rinse under warm water first to prevent a soupy filling. Let everything heat through for a few minutes.
Assemble and Bake the Casserole
- Pour the hot chicken and vegetable mixture into a 9x13-inch casserole dish.
- Now for the twist! If using refrigerated biscuit dough, gently fold 1/2 cup of shredded sharp cheddar and 1 teaspoon of dried herbs (like thyme or poultry seasoning) into the dough. Arrange the biscuits evenly over the hot filling. Don't press them down; just let them rest on top.
- Bake for 25-30 minutes. You'll know it's done when the biscuit topping is a deep golden brown and the filling is bubbly and hot around the edges.

Notes
This chicken pot pie casserole is a true one-dish meal. For an even thicker gravy, add an extra heaping tablespoon of flour when making the roux. If your frozen veggies have a lot of ice crystals, rinse them under warm water and drain completely to prevent a watery filling. This recipe is fantastic for meal prep; the filling can be prepared up to 2 days in advance or frozen without the biscuit topping.
