My aunt brings this ultimate cozy casserole to every Sunday dinner and there are never leftovers. It only takes 4 ingredients to make a completely filling meal

This slow cooker 4-ingredient chicken and stuffing is the kind of cozy casserole my Midwestern family expects at every Sunday dinner. It reminds me of the church-basement potlucks I grew up with: tender chicken, a rich, creamy sauce, and a savory bread stuffing that turns golden and fluffy on top. It’s a complete, stick-to-your-ribs meal made with pantry-friendly ingredients and almost no prep—exactly the sort of practical comfort food busy home cooks lean on when they want something filling without fuss.

Because this casserole already combines protein and starch, I like to keep the sides light and fresh. A simple green salad with a tangy vinaigrette or steamed green beans with a squeeze of lemon cut through the richness nicely. If you want to stretch the meal for a crowd, serve it with roasted carrots or a tray of buttered corn. A crisp white wine or iced tea pairs well, and for dessert, something simple and bright—like fresh fruit or a lemony bar cookie—balances the hearty, creamy flavors.

Servings: 6

2 pounds boneless, skinless chicken breasts

Lightly grease the inside of a 5- to 6-quart slow cooker with cooking spray or a thin film of oil to help with cleanup and prevent sticking.

Place the boneless, skinless chicken breasts in a single layer on the bottom of the slow cooker. If the pieces are very thick, you can cut them in half crosswise so they cook more evenly and are easier to serve.

In a medium bowl, whisk together the cream of chicken soup and the chicken broth until the mixture is smooth and evenly combined. This creates the creamy, savory sauce that will keep both the chicken and stuffing moist.

Pour the soup-and-broth mixture evenly over the chicken breasts, making sure all of the chicken is covered in the sauce. Some of the liquid will pool around the chicken, which is what you want—it will help steam and braise the meat as it cooks.

Sprinkle the dry seasoned stuffing mix evenly over the top of the sauce-covered chicken. Do not stir. You want the stuffing to sit on top so it can absorb steam and some surface moisture while still forming a golden, slightly crisp layer in spots.

Cover the slow cooker with the lid and cook on LOW for 4 to 5 hours, or until the chicken is cooked through and tender (it should reach an internal temperature of 165°F and shred or slice easily) and the stuffing on top is soft, moist, and lightly golden around the edges.

Once cooked, use two forks to gently pull the chicken into large, rustic chunks right in the slow cooker, folding it just slightly into the creamy sauce while keeping most of the stuffing layer on top. This gives you tender pieces of chicken with a blanket of fluffy, savory stuffing.

Taste a bit of the sauce and stuffing and adjust the seasoning at the table if needed with a pinch of salt and freshly ground black pepper. Serve the chicken and stuffing hot, scooping down through the golden stuffing layer to capture some of the thick, creamy yellow sauce and tender chicken in every portion.

Because this recipe is built on four core ingredients, any variations should be thoughtful so you keep the spirit of a simple, cozy casserole. For a slightly richer flavor, swap one can of cream of chicken soup for cream of mushroom—this adds an earthier note without changing the process. If you prefer darker meat, you can use boneless, skinless chicken thighs in place of breasts; they stay especially juicy after several hours in the slow cooker. To encourage more browned, toasty bits in the stuffing, crack the slow cooker lid open slightly for the last 20–30 minutes of cooking, which lets some steam escape and dries the top just enough. If your stuffing looks a bit dry toward the end, drizzle in a few extra tablespoons of warm chicken broth around the edges (not over the entire top) to keep the texture moist and fluffy. For those cooking ahead, you can assemble the dish (chicken, sauce, and stuffing on top) in the insert, cover, and refrigerate up to 12 hours; let it sit at room temperature while you preheat the slow cooker, then cook as directed, adding up to 30 minutes to the total time if everything went in cold. Finally, if you like a little color when serving, garnish individual plates with chopped fresh parsley or chives—added at the end so they don’t count as a core ingredient in the base recipe but still bring a fresh contrast to the creamy, comforting casserole.
