If you need a side dish that disappears from the table faster than you can say seconds, please, Jiffy Cornbread Casserole is it. Six ingredients, one bowl, and about five minutes of actual work — this is the recipe everyone begs you to bring every single holiday.

Why Everyone Loves This Recipe
There is something almost unfair about how easy this casserole is. You dump everything into a bowl, stir it together, and the oven does the rest.
The result is a dish that sits right between a fluffy cornbread and a creamy pudding — moist all the way through, slightly sweet, with a golden top that practically crackles when you cut into it. It is the definition of crowd-pleaser comfort food.
What You Need
The beauty here is the short list. Here is what makes this casserole so special:
Jiffy Corn Muffin Mix — The base of everything. Do not substitute; the specific blend of flour, cornmeal, and leavening is what gives this its signature texture.
Whole Kernel Corn — Drained canned corn adds little pops of texture and a bit of chew throughout the casserole.
Creamed Corn — This is the secret to the moist, almost custardy interior. Do not drain it — the liquid is everything.
Sour Cream — Adds richness and a subtle tang that balances the sweetness of the corn. It also keeps the crumb incredibly tender.
Eggs — Two eggs bind the whole thing together and give it structure so it slices cleanly.
Melted Butter — Half a cup. Yes, really. This is what makes it taste like a special occasion side dish.
How To Make Jiffy Cornbread Casserole
Step 1: Preheat your oven. Set it to 350 degrees F and grease a 9×13-inch baking dish with butter or nonstick spray. You want it well-coated so the edges get a golden, slightly crispy crust.
Step 2: Mix the batter. In a large bowl, combine the Jiffy mix, drained whole kernel corn, creamed corn, sour cream, eggs, and melted butter. Stir until everything is just combined — a few lumps are perfectly fine and actually welcome here.
Step 3: Pour and spread. Pour the batter into your prepared baking dish and spread it into an even layer. It will be thick and look almost like a dense pudding at this point — that is exactly right.
Step 4: Bake. Slide it into the oven and bake for 45 minutes, until the top is deeply golden brown and a toothpick inserted in the center comes out clean. The edges will pull away from the sides of the dish slightly when it is done.
Step 5: Rest and serve. Let the casserole rest for 5 minutes before cutting into it. This lets the interior set up so you get clean, beautiful squares. Serve warm with a pat of butter on top.

Tips and Variations
Want to make it even more decadent? Stir in a cup of shredded sharp cheddar cheese before baking. The cheese melts into the batter and creates pockets of savory richness that play perfectly against the sweet corn.
For a little heat, add a small can of diced green chiles or a pinch of cayenne to the mix. It gives the casserole a subtle kick that adults especially love.
This casserole reheats beautifully. Cover leftovers with foil and warm in a 325-degree oven for about 15 minutes, or microwave individual portions for 60 to 90 seconds. It stays moist for up to four days in the refrigerator.
Make It Ahead
This is one of those rare dishes that is genuinely better made in advance. Mix the batter the night before, cover the dish tightly with plastic wrap, and refrigerate. When you are ready to bake, pull it out while the oven preheats and add five extra minutes to the bake time.
You can also bake it fully and reheat it the day you need it — it holds incredibly well and the texture does not suffer at all. That makes it an absolute lifesaver for Thanksgiving, Christmas, or any big gathering where oven real estate is at a premium.
