Tips & Tricks
- Day-old bread works best because it absorbs the egg mixture without becoming soggy.
- Shred your own cheese for the smoothest melt.
- Swap cheddar with mozzarella, Monterey Jack, or Swiss cheese.
- Add diced tomatoes, broccoli, or kale for more vegetables.
- Use turkey sausage or chicken sausage if preferred.
- Let the casserole rest before slicing for cleaner servings.
- Double the recipe for large gatherings by baking in two dishes.
