Description
Chicken Pot Pie Casserole with biscuits is a creamy, hearty one-pan dinner built on a from-scratch thyme-seasoned filling loaded with cooked boneless chicken, tender vegetables, and a golden Pillsbury Grands biscuit topping. Ready in under an hour, it is one of the most satisfying casserole recipes for dinner that the whole family will request on repeat.
Ingredients
- 2 cups frozen, fully-cooked grilled chicken breast strips, cubed (or rotisserie chicken)
- 1 tbsp canola or vegetable oil (for sauté)
- ¼ cup canola or vegetable oil (for roux)
- ½ cup fresh or frozen chopped onions
- ½ cup chopped celery
- ½ cup frozen chopped carrots
- ¼ cup all-purpose flour
- 2 cups low-sodium chicken stock
- 1 (12 oz) can evaporated milk
- ½ cup frozen peas
- ½ cup frozen French-cut green beans
- 1 tsp salt
- ½ tsp black pepper
- 1 tsp dried thyme
- â…› tsp cayenne pepper
- 1 (16 oz) package refrigerated biscuit dough (Pillsbury Grands recommended)
- 1 large egg, beaten
Instructions
- Prep and Preheat: Wash hands with soap and water. Reheat frozen chicken strips per package directions, then cut into bite-sized pieces. Preheat oven to 350°F. Wash counters and produce before chopping.
- Sauté the Vegetables: Heat 1 tablespoon oil in a large pan over medium heat. Add onions, celery, and frozen carrots. Cook for approximately 5 minutes until tender.
- Build the Roux: Add the remaining ¼ cup oil to the pan. Once hot, sprinkle flour over the vegetables and whisk constantly for 60 seconds. Wash hands after handling raw flour.
- Add Liquid and Simmer: Pour in chicken stock slowly while whisking constantly to prevent lumps. Stir in evaporated milk until smooth. Bring to a gentle simmer.
- Finish the Filling: Reduce heat to medium-low. Add chicken, peas, green beans, salt, pepper, thyme, and cayenne. Stir well and simmer 2 minutes. Taste and adjust seasonings.
- Assemble: Transfer hot filling to a greased 9×13-inch baking dish. Arrange biscuits on top of the filling in a single layer. Brush each biscuit with beaten egg. Wash hands after handling raw egg.
- Bake: Bake at 350°F for 20 to 25 minutes until biscuits are deep golden brown and a food thermometer inserted in the center reads 165°F.
- Rest and Serve: Let the casserole rest for 5 minutes before serving to allow the filling to set.
Notes
Whisk flour into oil for a full 60 seconds before adding any liquid to eliminate raw flour taste. Keep the filling hot before topping with biscuit dough so the bottoms begin cooking immediately. For a flakier topping, substitute chicken pot pie with crescent rolls. Pull the dish from the oven the moment the thermometer reads 165°F to prevent the filling from drying out.
