This sweet corn casserole has everything a great comfort-food side should offer: a tender crumb, creamy texture, buttery flavor, and a gentle sweetness that pairs with nearly any main course. The canned whole corn adds pleasant little pops of texture, while the creamed corn keeps every bite moist.
The recipe is especially helpful when you need a dependable dish without a long ingredient list. There is no complicated sauce to prepare, no mixer required, and no special technique beyond stirring the batter gently.
It is also an excellent make-ahead choice for a busy dinner. While the casserole needs to be baked before serving for the best texture, the ingredients can be measured and the baking dish prepared ahead of time.

Ingredients You’ll Need
The ingredient list is short, but each item has an important job. Jiffy corn muffin mix supplies corn flavor and structure, while the eggs help the casserole set as it bakes.
- Jiffy corn muffin mix: One 8.5-ounce box creates the familiar lightly sweet corn-bread flavor and gives the casserole body.
- Whole-kernel corn: One 15-ounce can adds texture. Drain it thoroughly so extra liquid does not make the batter loose.
- Creamed corn: One 15-ounce can goes into the bowl undrained. Its moisture is essential to the soft, spoonable center.
- Sour cream: One cup adds richness and a slight tang while helping keep the baked casserole tender.
- Unsalted butter: Half a cup, or one stick, provides a buttery flavor and smooth texture.
- Eggs: Two large eggs help bind the ingredients and set the casserole without making it firm or dry.
- Salt and black pepper: These are optional, but a quarter teaspoon of each can sharpen the corn’s flavor.
For a thicker casserole, use a deep 8-by-8-inch dish. For a wider casserole with more golden surface area, use a greased 9-by-13-inch dish.

How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C). Grease a 9-by-13-inch casserole dish, making sure to coat the bottom and sides lightly so the finished casserole serves easily. If you prefer a thicker result, prepare a deep 8-by-8-inch dish instead.
Step 2: Melt the unsalted butter and allow it to cool slightly if it is very hot. In a large bowl, whisk the melted butter with the sour cream and two eggs until smooth and evenly blended.
Step 3: Add the Jiffy corn muffin mix, drained whole-kernel corn, and creamed corn. Remember to leave the creamed corn undrained because that liquid helps give the casserole its moist, creamy center.
Step 4: Add the optional salt and black pepper if you want a little extra seasoning. Stir the mixture just until no dry pockets of muffin mix remain, taking care not to overmix the batter.
Step 5: Pour the batter into the greased baking dish. Use a spatula or the back of a spoon to spread it into an even layer so the edges and center bake at a similar rate.
Step 6: Bake for 45–55 minutes. Start checking near the lower end of the range, looking for lightly golden edges and a center that is set but still slightly moist.
Step 7: Remove the casserole from the oven and let it rest for 5–10 minutes before serving. The center will firm gently during this time, making it easier to scoop while preserving the soft texture.
Pro Tips for the Best Corn Casserole
Drain only the whole-kernel corn. The liquid in creamed corn is not excess water to discard; it is part of the recipe’s moisture. Drain the regular corn well, but pour the creamed corn straight into the mixing bowl.
Do not overmix. Once the muffin mix disappears into the wet ingredients, stop stirring. Too much mixing can produce a denser texture rather than the soft, tender consistency this casserole is known for.
Watch the center, not just the clock. Oven temperatures and baking dishes vary, so use the visual cues as your guide. The center should be just set and slightly moist, not wet or liquid, and the casserole will continue firming as it rests.
Use the right dish for your preferred texture. A 9-by-13-inch dish makes a broad casserole with more browned edges. A deep 8-by-8-inch dish creates a thicker center and may need careful checking near the end of the 45–55 minute baking window.
Keep the basic recipe balanced. Sugar is usually unnecessary because the muffin mix and corn already provide sweetness. If you prefer a sweeter, more dessert-like side, add 1–2 tablespoons of sugar.
Serving Ideas for Dinner
Serve this corn casserole warm as a side dish with roasted chicken, baked ham, grilled meats, or a holiday turkey. Its creamy sweetness is particularly good alongside savory gravy, roasted vegetables, and crisp green salads.
For a festive meal, pair it with pecan crumb sweet potatoes for a table filled with warm, comforting flavors. The corn casserole also provides a soft contrast to crisp roasted potatoes or fresh green beans.
Although it is flavorful enough to stand on its own, the casserole benefits from a simple finishing touch. Add a little chopped parsley just before serving for color, or bring it to the table in the baking dish so everyone can enjoy the golden edges.
If you are planning a casual family dinner, serve leftovers with an easy turkey casserole for a filling second-day meal.
Storage and Reheating
Let leftover casserole cool, then cover it tightly and refrigerate it. Store it in the refrigerator and enjoy it within a few days for the best flavor and texture.
Reheat individual portions in the microwave until warmed through, or place the covered casserole in a moderate oven until hot. Reheating gently helps prevent the edges from becoming dry before the center is warm.
If the casserole seems slightly firmer after chilling, that is normal. The sour cream, eggs, and corn mixture softens again as it warms, though it will not be quite as delicate as it is straight from the oven.
For a breakfast-inspired dinner spread, this casserole also pairs nicely with cheesy tater tot casserole, especially when serving a crowd with different tastes.
The Best Sweet Corn Casserole Recipe
Ingredients
Method
- Heat the oven to 350°F (175°C) and grease a 9-by-13-inch casserole dish. A deep 8-by-8-inch dish may also be used for a thicker casserole.
- In a large mixing bowl, whisk together the melted butter, sour cream, and eggs until the mixture is smooth.
- Stir in the Jiffy corn muffin mix, drained whole-kernel corn, and undrained creamed corn. Add the salt and black pepper if desired.
- Mix only until the ingredients are combined. Do not overmix, since a gentle stir helps the casserole stay soft and tender.
- Pour the batter into the prepared dish and spread it evenly. Bake for 45–55 minutes, until the center is set, the edges are lightly golden, and the middle still looks moist.
- Remove the casserole from the oven and let it rest for 5–10 minutes. This short rest allows the center to firm up while keeping its creamy texture.
