Classic Jiffy Corn Casserole

The first time I brought this corn casserole to a potluck, my friend Sarah actually texted me later that night begging for the recipe. She said her husband kept going back for thirds, which is basically the highest compliment a Southern side dish can receive.

I discovered this recipe during a chaotic Thanksgiving when my aunt showed up with a grocery bag and said we needed a backup side dish. We threw everything together in my tiny apartment kitchen while the turkey took forever, and honestly, that casserole upstaged everything else on the table.

Ingredients

• 1/2 cup melted butter: Use real butter here, it creates that gorgeous golden crust and adds depth you cannot fake
• 1 cup sour cream: Full fat is best, it creates that creamy almost custard like texture that makes people swoon
• 2 large eggs: Room temperature eggs blend more smoothly into the mixture
• 1 can whole kernel corn: Drain this well so the casserole sets properly instead of getting soupy
• 1 can creamed corn: This is the secret weapon that makes it taste like it simmered all day
• 1 box Jiffy Corn Muffin Mix: Do not overthink this or try to substitute with something fancy
• Salt and pepper: Even though it is sweet, a little seasoning makes all the flavors pop

Instructions

Get your oven ready:

Preheat to 350 degrees and butter a 9x13 dish, getting into all the corners so nothing sticks

Whisk the wet stuff:

In a big bowl, beat the melted butter, sour cream, and eggs until they are completely smooth and no white streaks remain

Add the corn and mix:

Dump in both cans of corn and the Jiffy mix, stirring just until everything is combined, the batter will be thick

Spread it out:

Pour into your prepared dish and use a spatula to even out the top, this helps it bake evenly

Bake until golden:

Let it go for 45 to 50 minutes until the top is a beautiful brown and a knife comes out clean from the center

Give it a moment:

Let the casserole rest for 10 minutes before serving, it will firm up slightly and be easier to scoop

My sister in law now requests this for every single family gathering, and I have learned to always make two because one mysteriously vanishes before we even sit down to eat.

Make It Your Own

Cheddar cheese folded into the batter takes this from good to incredible, or try diced jalapeños if your crowd likes a little heat.

Timing Is Everything

You can assemble this the night before and keep it in the refrigerator, just add about 5 minutes to the baking time if it goes in cold.

Serving Suggestions

This pairs perfectly with ham, fried chicken, or pretty much any comfort food main. Serve it alongside green beans for that classic Sunday dinner feel.

• A dollop of butter on top while warm is never a bad idea
• Fresh chives add a nice pop of color if you are feeling fancy
• Leftovers reheat beautifully in the microwave

There is something so comforting about a dish that never fails to make people happy, and this corn casserole has been that reliable friend at more tables than I can count.

Recipe Q&A

→ Can I make corn casserole ahead of time?

Absolutely. You can assemble the casserole up to 24 hours in advance and store it covered in the refrigerator. Bake when ready, adding a few extra minutes if baking cold. It also reheats beautifully—cover with foil and warm at 350°F for 15-20 minutes.

→ Can I substitute Jiffy corn muffin mix?

While Jiffy mix provides the classic taste, you can use any cornbread mix or homemade cornbread batter. Keep in mind that different brands may slightly alter sweetness and texture. For homemade, aim for about 1 cup of cornmeal-based mix.

→ Why is my corn casserole runny?

The casserole should have a creamy, pudding-like consistency when hot but will set more firmly as it cools. If it's excessively runny after 45-50 minutes, it may need additional baking time. The center should jiggle slightly like gelatin when done.

→ What can I add to enhance the flavor?

Shredded cheddar cheese is a popular addition—stir 1 cup into the batter or sprinkle on top during the last 10 minutes of baking. Chopped green onions, diced jalapeños, or a pinch of cayenne pepper add savory depth. For herb notes, try fresh chives or parsley.

→ Can I freeze corn casserole?

Yes, it freezes well. Wrap the cooled, baked casserole tightly in plastic wrap and foil, then freeze for up to 3 months. Thaw overnight in the refrigerator before reheating. You can also freeze unbaked batter, though fresh baking yields the best texture.

→ What main dishes pair well with corn casserole?

This versatile side complements roasted turkey, ham, baked chicken, or meatloaf. It's particularly popular alongside holiday roasts and Southern classics like fried chicken or barbecue. As a hearty vegetarian option, it pairs nicely with a simple green salad.
