Ingredients
| Ingredient | Quantity | Notes |
| Canned Whole Kernel Corn | 1 can (15 oz) | Drained well |
| Cream-Style Corn | 1 can (15 oz) | Do not drain |
| Corn Muffin Mix | 1 box (8.5 oz) | Jiffy brand is standard |
| Sour Cream | 1 cup | Full fat recommended |
| Unsalted Butter | 1/2 cup | Melted |
| Large Eggs | 2 count | Room temperature |
Step-by-Step Instructions
Preparation
- Preheat your oven to 375 degrees Fahrenheit.
- Grease a 9×13 inch baking dish with non-stick cooking spray or butter.
Mixing
- Combine the melted butter and sour cream in a large mixing bowl until smooth.
- Whisk in the eggs until the mixture is fully incorporated.
- Fold in the canned whole kernel corn and the cream-style corn.
- Stir the corn muffin mix into the wet ingredients until just combined.
Baking
- Pour the batter into the prepared baking dish and smooth the top.
- Bake the casserole for 40 to 45 minutes until the edges are golden brown.
- Check for doneness by inserting a toothpick into the center to ensure it comes out clean.
- Rest the dish for 10 minutes before serving.
Chef Tips for Perfect Results
- Use room temperature eggs to ensure the batter emulsifies properly during the mixing stage.
- Drain the whole kernel corn thoroughly to prevent the casserole from becoming soggy or watery in the middle.
- Allow the dish to rest after removing it from the oven to let the center set properly for easier slicing.
- Add a pinch of salt or a dash of black pepper if you prefer a more savory flavor profile.
Common Mistakes to Avoid
- Mixing the batter for too long will create a tough texture; stir only until the dry ingredients are moistened.
- Using cold ingredients can result in an uneven rise; always bring your eggs and sour cream to room temperature first.
- Cutting the casserole immediately after baking causes the soft center to collapse; let it sit to firm up.
- Overbaking turns the edges dry and hard; pull the dish from the oven as soon as the center is set.

Frequently Asked Questions
Can I make this sweet corn casserole ahead of time?
You can assemble the mixture up to 24 hours in advance and store it covered in the refrigerator. Simply bake the casserole according to the instructions just before you plan to serve it.
How do I know when the casserole is fully baked?
The casserole is finished when the edges are deep golden brown and a toothpick inserted into the center comes out clean. Avoid relying solely on time; visual cues are more accurate for golden results.
What is the best way to substitute sour cream?
Plain Greek yogurt serves as the best direct substitute for sour cream without changing the final texture significantly. It maintains the necessary acidity and moisture to ensure the casserole rises properly.
Why is my corn casserole mushy in the middle?
A mushy center usually indicates that the excess liquid from the canned corn was not drained properly. Always drain your whole kernel corn well and ensure the dish rests for 10 minutes to allow the starches to set.
Can I serve this as a main course?
This dish is primarily categorized as a side, though you can boost the protein by adding shredded cheese or roasted peppers. Pair it with a side salad to create a balanced vegetarian meal.
This sweet corn casserole stands as a testament to the magic of simple ingredients. By following these precise steps, you create a dish that satisfies cravings and anchors any meal. Enjoy the warm, buttery sweetness that makes this recipe a household staple for years to come.
