For an extra layer of flavor, consider adding a pinch of smoked paprika or a dash of Worcestershire sauce to the mayonnaise mixture. Feel free to experiment with different types of cheese. Gruyere, cheddar, or even a spicy pepper jack would be delicious additions. To prevent the croutons from becoming too soggy, you can lightly toast them in a dry skillet or oven before adding them to the casserole. If you don't have red onions on hand, yellow or white onions can be substituted. Sautéing the onions before adding them to the casserole will mellow their flavor. Leftovers can be stored in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through.
