Ingredients
Instructions
- Saute onions in butter until they are clear and slightly browned.
- Layer two-thirds of the shredded Swiss cheese and the sautéed onions in a 2-quart casserole dish.
- Heat the cream of chicken soup, milk, and soy sauce in a saucepan until warm.
- Stir the soup mixture and pour it over the cheese and onion layers in the casserole.

Tips & Substitutions
For added flavor, consider using a mix of cheeses like Gruyère or cheddar along with Swiss. If you're short on time, you can use pre-sliced onions or even frozen onion slices. Ensure the onions are sautéed until they are just golden to enhance their sweetness. For a lighter version, substitute the cream of chicken soup with a homemade white sauce or a lower-fat alternative.
Serving Suggestions
This casserole makes a delightful side dish for any protein, especially chicken recipes or a roast. Serve it alongside a fresh salad or some steamed vegetables for a complete meal. For a comforting twist, consider pairing it with a bowl of Spinach Soup for a hearty dinner.
