This Chicken and Biscuit Casserole is creamy, hearty, and baked with biscuits on top for an easier twist on chicken pot pie. A perfect comfort food dinner.
Preheat oven to 375°F and lightly grease a 13x9-inch baking dish with non-stick spray.
Melt butter in a large skillet over medium-high heat. Add the diced carrots, celery, onion, and ½ teaspoon salt. Cook, stirring often, until the vegetables soften, about 5–7 minutes.
Sprinkle flour over the vegetables and stir well. Cook for 2 minutes to remove the raw flour taste.
Gradually whisk in the milk, chicken broth, mustard powder, garlic powder, dried thyme, and remaining salt. Bring to a boil, then reduce to medium heat and simmer until the mixture thickens, 3–5 minutes.
Fold in the shredded chicken and frozen peas until combined. Taste and adjust seasoning as needed.
Transfer the mixture to the prepared casserole dish, spreading it evenly.
Place the biscuit dough pieces on top of the filling in a single layer. Lightly season with salt and pepper, or brush with melted butter for extra flavor.
Bake uncovered for 22–25 minutes, until the biscuits are golden brown and the filling is bubbling.
Remove from oven and let rest for 5 minutes before serving.
Notes
Chef Jenn’s Tips
Use a cast iron skillet if you have one—it holds heat well and can go straight from stovetop to oven.
Brushing the biscuits with melted butter before baking makes them extra golden and flavorful.
Add corn, green beans, or even mushrooms to bulk up the veggie mix.
Letting the dish rest before scooping helps keep the filling creamy instead of runny.
