I first made this casserole for a snowy Thanksgiving when we had fewer side dishes than usual It was such a hit that now even the picky eaters ask for seconds at every gathering

  • Whole kernel corn canned: brings bursts of sweet juicy corn in every bite look for cans with only corn water and salt for the best flavor
  • Cream style corn: gives the casserole its luscious creamy base choose a brand with a smooth consistency
  • Sour cream: adds tang and makes the inside extra tender full fat makes a richer dish
  • Unsalted butter melted: gives the casserole an addictive buttery flavor high quality butter amps up the taste
  • Large eggs: bind everything and help the casserole set up in the oven go for fresh eggs when possible
  • Corn muffin mix like Jiffy: adds subtle sweetness and creates that light fluffy bread texture check the date for freshness
  • Shredded cheddar cheese optional: but recommended for melt and flavor sharp cheddar stands out best grate it yourself for the creamiest finish

Step-by-Step Instructions

Preheat the Oven:
Set your oven to 350 degrees Fahrenheit or 175 degrees Celsius Grease a 9 by 9 inch or 9 by 13 inch baking dish with butter or nonstick spray so the casserole releases easily later
Mix the Wet Ingredients:
In a big mixing bowl combine the drained whole kernel corn cream style corn sour cream melted butter and eggs Stir everything until completely blended with a spoon or spatula so no streaks remain
Add Corn Muffin Mix:
Sprinkle the corn muffin mix evenly over the wet ingredients Stir just until no dry patches show Avoid overmixing which can make the casserole dense
Fold in Cheese:
If using cheddar gently fold it through so it is evenly distributed This step makes for gooey pockets of cheese in every serving
Pour into Baking Dish:
Transfer the mixture into your greased baking dish Spread it out to the corners with a spatula and smooth the top so it bakes evenly
Bake the Casserole:
Place the dish on the center rack and bake for 45 to 55 minutes The top should be golden brown and the center just set It is ready when a toothpick poked into the middle comes out mostly clean with a few moist crumbs
Cool Slightly and Serve:
Allow the casserole to cool in the dish for 5 to 10 minutes before serving This helps it firm up and makes slicing easier

My favorite touch in this casserole is the sharp cheddar which melts perfectly and creates an irresistible cheesy top It always reminds me of my grandmother who insisted on extra cheese the crisp buttery edges made this a family classic that brings back so many happy holiday memories every time

Storage Tips

Let the casserole cool completely before covering tightly with foil or plastic wrap You can refrigerate it for up to four days To reheat pop slices in the microwave or warm the whole dish in a low oven Keep in mind the cheese on top may crisp up even more the second time around

Ingredient Substitutions

You can swap Greek yogurt for sour cream if you want a lighter tangy twist If you are out of canned cream style corn stir in extra whole corn and a splash of milk for creaminess To make it gluten free use a packaged gluten free corn muffin mix and check all can labels for hidden gluten

Serving Suggestions

Corn casserole shines alongside favorites like roast chicken barbecue brisket or pork chops For vegetarians pair it with a salad of fresh tomatoes and cucumbers or serve it with a bowl of warm black bean chili At Thanksgiving it always finds a place next to the stuffing and mashed potatoes
