This Jiffy corn casserole with sour cream is a creamy, sweet, and golden-topped side dish that’s perfect for potlucks, holidays, or any gathering. With just five simple ingredients and 10 minutes of prep, it’s an easy crowd-pleaser that disappears fast.
For a crispier top, bake uncovered for the full time or broil for the last 1-2 minutes. The casserole can be assembled up to 24 hours ahead and refrigerated; add 5-10 minutes to baking time. Leftovers keep in the fridge for up to 4 days and can be frozen for up to 3 months. For a gluten-free version, use a gluten-free cornbread mix. For a dairy-free version, use plant-based butter and dairy-free sour cream.
