This post is about cornbread casserole.

Cornbread Casserole Ingredients:
- 8oz - Jiffy corn muffin box mix
- 1/4 cup - Salted butter (melted)
- 15oz - Whole kernel corn can
- 15oz - Creamed corn
- 1 cup - Sour cream
- 2 - Large eggs
- 1/4 cup - Granulated sugar
- 1/2 tsp - Salt
Materials:
- Mixing bowl
- Whisk or spoon
- 9x9-inch baking dish (glass preferred)

Cornbread Casserole How-To:
1. Preheat your oven to 350°F (175°C).
Lightly grease a 9x9-inch baking dish with nonstick spray or butter.
2. Melt the butter, but allow it to cool slightly so it’s warm—not hot—before mixing. (Hot butter can scramble the eggs.)
3. In a large mixing bowl combine Jiffy mix, melted butter, drained whole kernel corn, creamed corn, sour cream, eggs, sugar, and salt. Stir until fully combined. Avoid over-mixing.
4. Pour the batter into the prepared dish and smooth the top.
(Optional: Sprinkle a little sugar on top now or halfway through baking for a sweet crust.)
5. Bake for 40-50 minutes, or until a toothpick inserted in the center comes out clean and the center is set. Glass dishes tend to take a little longer than metal.
6. Cool slightly before serving. Cut into squares for a cleaner presentation, or scoop it out with a spoon for a more rustic serving style.

Recipe FAQs:
Can I make this ahead of time?
Yes! Prepare the batter a day ahead and refrigerate it covered. Let it come to room temperature before baking the cornbread casserole.
Can I use a larger baking pan?
Yes! Using a larger pan like a 9x13-inch dish will result in a thinner cornbread casserole, which bakes faster. Start checking for doneness around 30–35 minutes. The edges may brown more quickly, so keep a close eye to avoid over-baking.
Can I freeze cornbread casserole?
Yes. Let it cool completely, then wrap tightly and freeze for up to 2 months. Reheat the cornbread casserole in the oven until warmed through.

Why is my casserole too wet or undercooked?
This usually means it needs more bake time. Ovens vary—always test with a toothpick in the center. It should come out clean and the middle should be set.
Can I make this cornbread casserole gluten-free?
Yes! Just substitute the regular Jiffy corn muffin mix with a gluten-free corn muffin mix (make sure it’s an 8.5 oz box equivalent). The texture may be slightly different, but it’ll still be delicious and moist like normal cornbread casserole.
