Optional substitutions:

Step-by-Step Instructions
1. Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter or non-stick spray.
2. In a large bowl, whisk eggs and melted butter until well combined. Add sour cream and whisk until smooth.
3. Fold in both cans of corn (drained whole kernel and creamed corn) – stir gently but thoroughly.
4. Gradually add the corn muffin mix while stirring; avoid overmixing to keep texture light and fluffy.
5. Pour batter evenly into prepared dish. Spread with a spatula to ensure even thickness.
6. Bake for 45–50 minutes until top is golden brown and edges pull away from the dish slightly. A toothpick inserted in the center should come out mostly clean (with a few moist crumbs).
7. Rest for 5 minutes before serving – this sets the casserole and prevents it from falling apart.
Pro tip for perfect texture: Check internal temperature reaches 200°F for a fully set custard-like center. For a firmer bite, bake 5 additional minutes. This Corn Casserole pairs wonderfully with other holiday side dishes like roasted vegetables or glazed ham.

Common Mistakes to Avoid
| Mistake | Solution |
|———|———-|
| Dry casserole | Don’t overbake; check at 45 minutes. Add 2 tbsp milk if batter looks thick. |
| Soggy center | Drain whole kernel corn thoroughly and avoid adding extra liquid. |
| Greasy texture | Use cold butter (melted but not hot) and room-temperature eggs for even emulsification. |
| Falls apart when sliced | Always let rest 5–10 minutes after baking. Refrigerate leftovers to firm up for next-day serving. |
| Too salty | Use unsalted butter and adjust salt in muffin mix if needed (Jiffy already contains salt). |

Storage & Meal Prep Tips
Refrigeration: Store leftover Corn Casserole in an airtight container for up to 5 days. Place parchment paper between layers to prevent sticking.
Freezing: Cool completely, wrap tightly in plastic wrap and foil, then freeze for up to 3 months. Thaw overnight in refrigerator before reheating.
Reheating:
– Oven: 350°F for 10–15 minutes (cover with foil to prevent drying)
– Microwave: 30-second intervals on 50% power
– Air fryer: 350°F for 5–7 minutes (crisps the edges beautifully)
Meal prep tip: Assemble the casserole the night before (without baking) and refrigerate. Add 10 minutes to baking time if starting from cold.

FAQs
1. Can I use frozen corn instead of canned?
Yes! Thaw 3 cups frozen corn and drain excess moisture. Reduce baking time by 5 minutes since frozen corn releases more liquid.
2. Why is my casserole runny in the middle?
The center should still jiggle slightly when done; it will set while cooling. Ensure oven temperature is accurate with an oven thermometer.
3. Can I make this dairy-free?
Absolutely—use vegan butter, coconut cream (with lemon juice), and a dairy-free cornbread mix. Expect slightly less rise but similar flavor.
4. How do I get a crispy top?
Sprinkle 1/4 cup crushed cornflakes or panko breadcrumbs mixed with 2 tbsp melted butter on top before baking. Remove foil for last 10 minutes.
5. Can I add protein like chicken or bacon?
Fold in 1 cup shredded cooked chicken or 1/2 cup cooked, crumbled bacon after mixing all ingredients. Bake as directed (add 5 minutes if using cold meat).
