The Best Cheesy Corn Casserole That Everyone Always Raves About
There are recipes you make once and forget, and then there are those you find yourself coming back to again and again — sometimes more than a dozen times a year. This cheesy corn casserole is absolutely one of those dishes. Golden on top, tender and moist inside, and packed with savory flavor from green onions, cheese, and bits of bacon, this baked beauty has earned a permanent spot on potluck tables, holiday spreads, and weeknight dinners alike.
If you have ever shown up somewhere and immediately become the most popular person in the room, this casserole is your secret weapon. It is the kind of dish people crowd around and ask for the recipe before they have even finished their first serving. Let us walk you through exactly how to make it.
Ingredients
- 1 box (8.5 oz) Jiffy corn muffin mix
- 1 can (15 oz) whole kernel corn, drained
- 1 can (15 oz) cream-style corn
- 1 cup sour cream
- 2 large eggs, beaten
- 1/2 cup unsalted butter, melted
- 1 1/2 cups shredded cheddar cheese, divided
- 4 strips bacon, cooked and crumbled
- 3 green onions, sliced (plus extra for topping)
- 1/2 small white onion, finely diced
- 1/2 teaspoon garlic powder
- 1/2 teaspoon black pepper
- 1/2 teaspoon salt
Method
- Preheat your oven to 350°F (175°C). Grease a 9×9 inch baking dish or a similar-sized casserole dish generously with butter or non-stick spray and set aside.
- In a large mixing bowl, combine the Jiffy corn muffin mix, whole kernel corn, cream-style corn, sour cream, beaten eggs, and melted butter. Stir everything together until just combined — do not overmix.
- Fold in one cup of the shredded cheddar cheese, the crumbled bacon, diced white onion, sliced green onions, garlic powder, salt, and black pepper. Mix gently until evenly distributed.
- Pour the batter into your prepared baking dish and spread it out into an even layer using a spatula.
- Sprinkle the remaining half cup of shredded cheddar cheese evenly over the top of the casserole. Add a few extra sliced green onions on top for color and freshness.
- Bake uncovered for 45 to 55 minutes, or until the top is deep golden brown and the center is set. A toothpick inserted into the middle should come out clean or with just a few moist crumbs.
- Remove from the oven and allow the casserole to rest for at least 10 minutes before slicing and serving. This helps everything firm up beautifully and makes it much easier to cut clean squares.
Tips for the Best Results
Do not skip the resting time after baking. It might be tempting to dive right in, but letting the casserole sit allows the texture to come together and makes for much cleaner, prettier slices when serving a crowd.
If you want a little heat, stir in a diced jalapeño or a pinch of cayenne pepper with the batter. It pairs wonderfully with the sweetness of the corn and the richness of the cheese.
This casserole reheats like a dream. Store leftovers covered in the refrigerator for up to four days. Warm individual portions in the microwave for about a minute, or reheat the whole dish in a 325°F oven for 15 to 20 minutes.
Why This Dish Is Always a Crowd Pleaser
There is something deeply comforting about a corn casserole that hits every note at once — slightly sweet, savory, cheesy, and just a little smoky from the bacon. It works as a side dish alongside grilled meats, roasted chicken, or holiday turkey, but honestly it is hearty enough to hold its own as a main course with a simple salad on the side. Once you bring this to a gathering, be prepared to hand out the recipe on repeat.
