This slow baked chicken and stuffing casserole is one of those cozy, no-fuss dinners that makes the whole house smell like home. It’s inspired by the classic Midwestern Sunday supper—simple ingredients, a can of soup or two, and a box of stuffing mix pulled together into something comforting and familiar. This is the kind of dish you pop in the oven on a busy school night or a chilly weekend afternoon and let it quietly do its thing while you help with homework or fold laundry. It’s also a great way to stretch a pack of chicken breasts into a hearty, family-style meal that feels special without taking all day in the kitchen.
This casserole pairs really nicely with simple, down-to-earth sides. I like to serve it with a green veggie—steamed green beans, roasted broccoli, or a simple side salad with ranch dressing all work well to balance the richness. A side of applesauce or sliced fresh fruit is always a hit with kids and adds a little sweetness to the plate. If you’re feeding a hungry crowd, you can add mashed potatoes or buttered egg noodles, even though the stuffing already brings the carbs—it’s very much in the spirit of Midwestern comfort to have more than one cozy side. And if you want to keep it extra easy, just add a pan of roasted carrots or a bag of frozen mixed veggies, and dinner is done.
Slow Baked Chicken and Stuffing Casserole
Servings: 6
Ingredients
2 pounds boneless, skinless chicken breasts (about 4–6 pieces)
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, depending on how salty your soups and stuffing are)
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 so they cook more 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 you can.
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.
Variations & Tips
For picky eaters, you can leave out the mixed vegetables and serve the casserole with veggies on the side instead. If your kids are sensitive to texture, chop the chicken into bite-sized pieces before baking so they get more of a “scoopable” casserole and fewer big chunks. You can also swap the cream of mushroom soup for more cream of chicken if mushrooms are a no-go. For a slightly lighter version, use reduced-fat soups and milk instead of whole milk, and go easy on the butter; just know the texture will be a bit less rich. If your family loves cheese, sprinkle 1–1 1/2 cups shredded cheddar or mozzarella over the sauce before adding the stuffing, or add a light layer of cheese on top of the stuffing in the last 10 minutes of baking so it melts but doesn’t burn. To add more veggies, stir in extra frozen peas, carrots, or corn with the mixed vegetables, or layer thinly sliced zucchini or mushrooms under the chicken. You can also use boneless, skinless chicken thighs instead of breasts for extra tenderness—just trim off excess fat and keep the same baking time. For a make-ahead option, assemble the casserole up to the point of baking, cover tightly, and refrigerate for up to 24 hours; when you’re ready to cook, let it sit on the counter for about 20–30 minutes while the oven heats, then bake as directed, adding 10–15 extra minutes if needed. This is a very forgiving recipe, so feel free to adjust the seasoning, soup flavors, and veggie mix to fit what your family loves most.
