Ingredients

• 2-3 tablespoons butter or margarine
• 3 large sweet onions or 4 medium white or yellow onions
• 2 cups shredded Swiss cheese (8 oz.)
• 1 can cream of chicken soup, undiluted (or cream of mushroom soup for a vegetarian option)
• 2/3 cup milk
• 1 teaspoon soy sauce
• 8 or so slices of French bread

Instructions

1. Prepare the Onions: Begin by slicing the onions. If you find yourself tearing up, a sharp knife or chilling the onions beforehand can help minimize crying.
2. Sauté the Onions: In a large sauté pan, melt the butter over medium heat. Add the sliced onions and sauté them until they become clear and slightly browned. This usually takes about 10-15 minutes, and it’s essential to stir occasionally to ensure even cooking.
3. Layer the Casserole: In a shallow 2-quart casserole dish, layer the sautéed onions. Sprinkle about two-thirds of the shredded Swiss cheese over the onions, and add pepper to taste.
4. Prepare the Sauce: In a saucepan, combine the undiluted cream of chicken soup, milk, and soy sauce. Heat over medium-low, stirring to blend the ingredients well.
5. Combine and Top: Pour the soup mixture over the onion and cheese layers in the casserole. Stir gently to combine the ingredients. Next, lay the slices of French bread on top of the casserole.
6. First Bake: Place the casserole in an oven preheated to 350°F (175°C) and bake uncovered for 15 minutes. This step allows the top of the bread to become nice and toasted.
7. Final Touch: After 15 minutes, push the bread slices under the sauce to soak up the flavors, then top with the remaining Swiss cheese.
8. Second Bake: Return the casserole to the oven and bake for an additional 15 minutes, or until the cheese is melted and bubbly.
