- Spread cream of mushroom soup over the onions.
- Sprinkle shredded cheese evenly over the layer.
- Repeat layering with remaining onions, soup, and cheese if desired.
- Beat eggs, add milk, salt, and pepper, then pour this mixture over the layered ingredients in the casserole dish.
- Sprinkle additional cracker crumbs and cheese on top.
- Bake at 350°F (175°C) until brown and bubbly, about 35-45 minutes.
Tips & Substitutions
For a richer flavor, consider using butter instead of margarine. If you want to lighten the dish, use low-fat cream of mushroom soup and substitute some or all of the milk with vegetable broth. You can also add cooked bacon or sausage for a meaty twist. For a vegetarian option, ensure the cream of mushroom soup is vegetarian-friendly. Feel free to adjust the amount of onions based on your preference for sweetness.
Serving Suggestions
This casserole is best served warm and pairs beautifully with a fresh green salad or steamed vegetables for a balanced meal. It also makes a great side dish for grilled meats or as a comforting main dish alongside crusty bread. For a complete dinner, consider serving it with Sweet And Sour Meatballs(Reduced Fat) for a delightful contrast.
