A creamy, cheesy corn casserole made with Jiffy mix, sour cream, and sharp cheddar. Perfect for cozy evenings and holiday gatherings, this easy side dish comes together in minutes and delivers rich, comforting flavor.
Shred your own cheese for best melting. Let ingredients come to room temperature for 20 minutes before starting. For a spicier version, add diced green chiles, cumin, and cayenne. For a lighter version, use reduced-fat sour cream, substitute two egg whites for one egg, and reduce butter to ¼ cup. Casserole can be assembled up to 24 hours ahead; add 5-10 minutes to baking time if starting cold. Leftovers keep in refrigerator for up to 4 days; reheat in oven at 350°F for 10-15 minutes. Freezes well for up to 3 months.
