Swiss chicken casserole is a retro meal that has been around for decades — the kind you’d spot in church cookbooks and on hand-me-down recipe cards.

It features chicken, Swiss cheese, condensed soup, and a buttery stuffing topping, so you’re working with familiar ingredients and simple steps. Mix the sauce in one bowl, toss the stuffing with butter, layer everything in the dish, and let the oven do the rest.

👉 Easy ingredient swaps

Chicken: Swap with turkey breast or cooked rotisserie chicken (just reduce bake time to about 25 minutes).
Swiss Cheese: Try provolone or mozzarella for milder flavor, or cheddar/Monterey Jack for sharper.
Cream of Chicken Soup: Cream of mushroom or cream of celery both work.
Stuffing Mix: Use any seasoned stuffing or make your own with cubed bread and herbs; toss with the melted butter as written.
Butter: Use olive oil in the same amount if needed.

✨ Variations

Extra Creamy: Stir ¼ cup cream cheese into the sauce before layering.
More Veggies: Add a layer of steamed broccoli, mixed veggies, or green beans before the sauce.

〰️ How to serve

Veggies — Pair with steamed mixed veggies, roasted broccoli, or a crisp side salad.
Bread — Garlic bread or soft dinner rolls.
Starches — Mashed potatoes, buttered noodles, or rice to soak up the sauce.

💬 FAQs

Can I prepare this casserole in advance?

Yes. Assemble everything through the stuffing layer, cover, and refrigerate up to 24 hours. Bake as directed, adding about 5-10 minutes to the bake time if starting from cold.

How long will leftovers keep?

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat covered in the oven at 350°F or microwave until warmed through.

Can this be frozen and reheated?

Yes. Let it cool completely, then cover tightly and freeze for up to 3 months. Thaw overnight in the fridge before reheating at 350°F until hot. You can add a little extra broth or sauce if it seems dry after freezing.
