For a richer flavor, consider using Gruyere or a blend of cheeses in addition to or instead of the Cheddar. If you prefer a less creamy casserole, reduce the amount of mayonnaise by 1/4 cup. Feel free to add other vegetables such as zucchini or bell peppers to the mix. A sprinkle of buttery breadcrumbs on top before baking adds a delightful crunch.

Jun 27, 2025I've made this casserole several times now, and it's always a crowd-pleaser. The only change I made was to use reduced-fat mayonnaise to cut down on the calories.
