- Add milk, Worcestershire sauce, and salt to the eggs and blend well.
- Place 4 slices of bread in a single layer in a buttered 1 1/2-quart casserole dish, trimming if necessary.
- Layer with half of the sautéed onion rings, melted butter, tuna, and shredded cheese.
- Repeat the layering process to make two more layers.

- Bake uncovered at 350°F (175°C) for 45 minutes or until golden brown.
Tips & Substitutions
For a creamier texture, consider adding a can of cream of mushroom soup to the mixture. You can substitute the bread with whole grain or gluten-free varieties for a healthier option. If you prefer a different flavor, try using pepper jack cheese for a bit of heat, or mix in some chopped bell peppers for added crunch. This casserole also pairs beautifully with Quick Tuna-Macaroni Salad.
Serving Suggestions
This casserole is a complete meal but can be served with a light salad for a refreshing contrast. Consider a simple green salad or a side of steamed vegetables to balance the richness of the dish. It also pairs well with crusty bread or a side of fruit for a more complete dining experience.
