This Jiffy corn casserole with sour cream and cheddar is a quick, easy, and crowd-pleasing side dish perfect for potlucks, holidays, or weeknight dinners. It combines sweet cornbread, tangy sour cream, and sharp cheddar for a creamy, golden, and utterly delicious casserole.
Don’t overmix the batter; a few lumps are fine. Room temperature ingredients help the batter come together smoothly. Let the casserole rest for 10-15 minutes after baking to set properly. For a spicier version, add diced jalapeño or green chiles. For a gluten-free version, use a gluten-free corn muffin mix and ensure cream-style corn is gluten-free.
