tips to make Overnight Breakfast Casserole
- Use day-old bread for the best texture. Stale bread absorbs the egg mixture better.
- Feel free to customize the casserole with your favorite ingredients. Swap different cheeses, meats, or vegetables based on what you have on hand.
- If you want a little spice, add some diced jalapeños or sprinkle some red pepper flakes in with the eggs.
- For extra creaminess, use half-and-half instead of milk.
