Corn Casserole Without Jiffy

This corn casserole builds its own cornbread base from scratch instead of relying on a boxed mix, using plain cornmeal, flour, and baking powder in place of the shortcut most versions call for.

Creamed corn and whole kernel corn both go into the batter, along with sour cream and melted butter, so the inside stays moist and slightly custardy even as the top turns deep golden and a little crisp around the cheese.

Cheddar folded into the batter and sprinkled over the top means every bite has some of that sharp, melted contrast against the sweet corn underneath.

Ingredients

• 1 cup yellow cornmeal
• 1/2 cup all-purpose flour
• 1/4 cup sugar
• 1 tablespoon baking powder
• 1/2 teaspoon salt
• 2 large eggs
• 1/2 cup sour cream
• 1/2 cup melted butter
• 1 (15 ounce) can creamed corn
• 1 (15 ounce) can whole kernel corn, drained
• 1 1/2 cups shredded cheddar cheese, divided

Why You’ll Love This Corn Casserole Without Jiffy

• Building the base from scratch means no boxed mix to track down, and you can see exactly what’s going into it.
• The mix of creamed corn and whole kernels gives a texture that’s both soft and slightly toothsome, not just one uniform mush.
• It’s a true one bowl recipe, mixed and poured straight into the baking dish with no separate steps.
• The cheddar folded into the batter and layered on top means cheese shows up in every bite, not just as a garnish.
• It reheats well, so leftovers the next day are nearly as good as fresh from the oven.

Ingredient Notes

Yellow cornmeal gives this casserole its color and classic cornbread flavor. A finer grind will produce a slightly smoother texture than a coarse, stone ground cornmeal, though either works fine here.

Creamed corn is what makes this casserole custardy rather than dense like a straightforward cornbread. Don’t substitute it with more whole kernel corn, since the creamed version is doing real textural work beyond just adding corn flavor.

Sour cream adds moisture and a slight tang that balances the sweetness from the sugar and creamed corn. Plain Greek yogurt is a reasonable substitute if that’s what’s on hand, though it will make the casserole taste a touch tangier.

Sharp cheddar holds up best against the sweetness of the corn, giving a stronger cheese flavor than a mild cheddar would. Shred it yourself from a block rather than buying pre-shredded cheese, since pre-shredded cheese often contains anti-caking additives that keep it from melting as smoothly into the batter.

Melted butter adds richness that a neutral oil wouldn’t bring, and it’s what gives the edges of the casserole that slightly crisp, browned quality visible once it comes out of the oven. Let it cool slightly before whisking it into the eggs so it doesn’t start cooking them on contact.

How to Make Corn Casserole Without Jiffy

Preheat the oven to 350°F and grease a 9-by-9-inch baking dish. Whisk together the cornmeal, flour, sugar, baking powder, and salt in a large bowl until evenly combined.

In a separate bowl, whisk the eggs, then stir in the sour cream and melted butter until smooth. Add the creamed corn and drained whole kernel corn and stir to combine.

Pour the wet ingredients into the dry ingredients and stir just until no dry streaks of cornmeal remain. Fold in half of the shredded cheddar, keeping the mixing gentle so the batter doesn’t get overworked.

Pour the batter into the prepared baking dish and spread it into an even layer. Sprinkle the remaining cheddar evenly over the top.

Bake for 40 to 45 minutes, until the top is deep golden and a toothpick inserted into the center comes out mostly clean, with maybe a few moist crumbs from the melted cheese. If the top is browning too quickly before the center sets, loosely tent the dish with foil for the last 10 minutes of baking.

Let the casserole rest for at least 10 minutes before cutting into it, since it firms up as it cools and is much easier to serve in clean squares once it’s had a few minutes to set. A wooden spoon or spatula works well for lifting out the first square, since the edges tend to be the crispest and can stick slightly to a thin metal spatula.

Tips for Success

• Don’t skip draining the whole kernel corn. Extra liquid in the batter will make the finished casserole soggier than intended.
• Shred your own cheese from a block for the smoothest melt, both in the batter and on top.
• Check for doneness with a toothpick in the center, not just the edges, since the middle takes longest to set.
• Let the casserole rest before cutting. It holds together much better sliced after 10 minutes than straight out of the oven.
• Loosely tent the dish with foil if the top browns faster than the center finishes baking.

Storage

Store leftover casserole in an airtight container in the fridge for up to 4 days. Reheat individual portions in the microwave, or warm the whole dish covered in a 300°F oven until heated through, which helps keep the top from drying out. This casserole freezes well too. Wrap tightly and freeze for up to 2 months, then thaw overnight in the fridge before reheating.

FAQ

Why skip the Jiffy mix?

Some people prefer to know exactly what’s in their food, avoid a specific ingredient in the boxed mix, or simply don’t have a box on hand. This version uses basic pantry staples to get a similar sweet, moist result without needing the shortcut.

Can I make this ahead of time?

Yes. Assemble the batter, pour it into the baking dish, cover, and refrigerate for up to a day before baking. You may need to add a few extra minutes to the bake time if it goes into the oven cold.

Can I use a different cheese?

Yes. Monterey jack or a pepper jack for some heat both work well in place of cheddar, though cheddar gives the closest flavor to a classic version.

Can I add extras like jalapeños or bacon?

Yes. Diced jalapeños or crumbled cooked bacon folded into the batter along with the corn are both common additions that don’t require changing the bake time.
