How to Make Slow Baked Chicken and Stuffing Casserole
Ingredients
- 2 pounds boneless, skinless chicken breasts
- 1 box (6 oz) stuffing mix (chicken or savory herb flavor)
- 1 can (10.5 oz) cream of chicken soup
- 1 can (10.5 oz) cream of mushroom or cream of celery soup
- 1 1/2 cups low-sodium chicken broth (divided: 1 cup + 1/2 cup)
- 1/2 cup milk
- 2 tablespoons butter, melted (plus extra for greasing the dish)
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon dried thyme (optional)
- 1/2 teaspoon dried parsley (optional, plus extra for garnish)
- 1/2 teaspoon salt (or to taste)
- 1/2 teaspoon black pepper
- 2 cups frozen mixed vegetables, thawed and drained (optional but recommended)
Directions
- Preheat your oven to 300°F (150°C). Lightly grease a 9×13-inch casserole dish with butter or cooking spray.
- In a medium bowl, whisk together the cream of chicken soup, cream of mushroom (or celery) soup, 1 cup of chicken broth, milk, garlic powder, onion powder, thyme, parsley, salt, and pepper until smooth.
- Spread the thawed mixed vegetables (if using) evenly in the bottom of the prepared casserole dish. Lay the chicken breasts on top of the vegetables in a single layer. If the pieces are very thick, you can slice them in half horizontally to ensure they cook evenly and stay tender.
- Pour the soup mixture evenly over the chicken, making sure each piece is well coated. Gently wiggle the dish so the sauce settles around the chicken and veggies.
- In a separate bowl, add the dry stuffing mix. Pour in the remaining 1/2 cup chicken broth and the melted butter. Stir just until the stuffing is evenly moistened—don’t overmix; you want some texture.
- Sprinkle the moistened stuffing mixture evenly over the top of the chicken and sauce, covering as much of the surface as possible.
- Cover the casserole dish tightly with foil. Bake at 300°F for 2 hours, letting it cook low and slow so the chicken gets very tender and the flavors meld together.
- After 2 hours, carefully remove the foil. Check that the chicken is cooked through (it should reach 165°F in the thickest part). If the top looks very wet, bake uncovered for an additional 10–15 minutes to let the stuffing crisp up a bit.
- Remove from the oven and let the casserole rest for 5–10 minutes before serving. Sprinkle with a little extra dried or fresh parsley for color, then scoop generous spoonfuls onto plates and enjoy.
How to Serve Slow Baked Chicken and Stuffing Casserole
Serve the casserole warm straight from the oven. It pairs well with a simple green salad or some crusty bread. Feel free to garnish with additional parsley for a pop of color.
