Ingredients for Chi Chi’s Corn Casserole
Comforting and familiar flavors come together in this easy side dish with a creamy texture.
| Ingredient | Amount | Notes |

| Canned Sweet Corn 🌽 | 4 cans | 15 oz each, drained |

| Corn Muffin Mix 🥞 | 1 box | 8.5 oz, like Jiffy |
| Large Eggs 🥚 | 2 whole | Beaten, room temperature |
| Shredded Cheddar Cheese 🧀 | 1 ½ cups | Sharp or mild variety |
| All-Purpose Flour 🌾 | ¼ cup | For thickening if needed |
| Granulated Sugar 🍚 | ¼ cup | Optional for extra sweetness |

The corn is non-negotiable here—Del Monte or Green Giant canned sweet corn gives the right balance of sweetness and texture. Most grocery stores carry the 15 oz size, which is perfect. The sour cream needs to be full-fat for that signature creamy consistency. For the muffin mix, Jiffy is the gold standard (find it near the baking aisle). The cheddar should be shredded from a block for the best melt.
No corn muffin mix? Cornbread mix at half the amount works in a pinch, though it’s slightly sweeter. Out of sour cream? Plain Greek yogurt is a great substitute at one-to-one ratio. Want extra richness? Swap the cheddar for Pepper Jack. The butter can be salted if that’s what you have—just skip the added salt in the recipe.
This casserole reheats like a dream—tastes even better the next day. Keeps in the fridge for 4-5 days or freeze for 2-3 months. Leftovers disappear fast, so double the batch if you’re feeding a crowd.

Step-by-Step Instructions for Corn Casserole
Here’s the method. Straightforward, tested, works every time.
Step 1: Preheat and Prepare the Base
Preheat your oven to 350°F and grease a 9×13-inch baking dish with a bit of the unsalted butter. I like to use a paper towel to spread it evenly, making sure to cover the bottom and sides completely to prevent sticking.
Drain all 4 cans of canned sweet corn thoroughly in a colander, pressing gently to remove excess liquid. Transfer the corn to a large mixing bowl. This step ensures your casserole sets properly without becoming watery.
Step 2: Mix Wet and Dry Ingredients
To the corn, add the 1 cup sour cream, 0.5 cup melted unsalted butter, 2 whole large eggs, 0.25 cup granulated sugar, 0.5 tsp salt, 0.25 tsp black pepper, 1 tsp onion powder, and 0.5 tsp garlic powder. Whisk everything together until the mixture is smooth and fully combined.
Next, stir in the 1 box corn muffin mix and 0.25 cup all-purpose flour until no dry spots remain. The batter will be thick but pourable. This combination gives the casserole its signature cornbread-like texture.
Step 3: Incorporate the Cheese and Bake
Fold in 1 cup of the shredded cheddar cheese (reserving the remaining 0.5 cup for topping). Pour the batter into your prepared baking dish and spread it evenly with a spatula. The surface should be smooth, with no lumps or dry patches.
Sprinkle the reserved 0.5 cup shredded cheddar cheese evenly over the top. This will create that irresistible golden, slightly crispy layer that contrasts perfectly with the creamy interior.
Step 4: Bake to Golden Perfection
Bake in the preheated oven for 45-50 minutes, or until the top is golden brown and the center is set. You can test this by inserting a toothpick into the middle—it should come out clean or with just a few moist crumbs.
The edges should pull away slightly from the sides of the dish, and the cheese on top will be bubbly and lightly browned. If the top begins to brown too quickly, tent the dish loosely with aluminum foil for the remaining baking time.
Step 5: Rest and Serve Warm
Remove the casserole from the oven and let it rest for 10 minutes before serving. This allows the dish to set fully and makes it easier to cut into neat squares. The interior will be creamy, with the sweetness of the corn balanced by the savory cheese and spices.
Serve warm, straight from the dish or plated individually. Each portion should have a crisp top layer giving way to a rich, custard-like filling that showcases the sweet corn and cheddar flavors perfectly.
Pro Tips For Making Chi Chi’S Corn Casserole
- Preheat the Oven: Set it to 350°F before mixing ingredients—this recipe bakes best with consistent heat from the start, and I learned this the hard way after pulling out a gooey center more than once.
- Drain the Corn: Use a colander and press the canned sweet corn lightly to remove excess liquid, or you’ll end up with a watery casserole that takes forever to set.
- Melt the Butter: Let the unsalted butter cool slightly after melting before mixing it with the eggs, or you’ll scramble them instead of blending them smoothly into the batter.
- Check at 45 Minutes: Ovens vary, and this casserole can go from perfect to over-browned fast—start testing for a golden top and clean toothpick around the 45-minute mark.
Flavor Customization for This Recipe
Savory Herb Twist
Add 1 tbsp fresh chives and 1 tbsp fresh parsley to the batter for a garden-fresh flavor. I also like stirring in 1 tsp dried thyme for an earthy note that complements the sweet corn beautifully. 🌿
Spicy Kick
For heat lovers, mix in 1 diced jalapeño (seeds removed) or ½ tsp cayenne pepper to the wet ingredients. The spice balances the sweetness perfectly. I’ve also had success with 1 tsp chipotle powder for a smoky heat.
Cheesy Upgrades
Swap the cheddar for Pepper Jack for extra zing, or mix in ½ cup crumbled cotija for a salty crumble. For a richer texture, add ½ cup cream cheese to the batter—it makes the casserole ultra-creamy.
Sweet Enhancements
Increase the granulated sugar to ⅓ cup if you prefer a dessert-like casserole. Another trick: stir in ½ cup crushed pineapple (drained well) for tropical sweetness. The natural juices add moisture too.
Crunchy Topping
Before baking, sprinkle ½ cup crushed Ritz crackers or cornflakes over the cheese for extra crunch. I’ve also used panko breadcrumbs mixed with 2 tbsp melted butter for a buttery, crispy topping. 💛
Southwest Flavor
Add 1 cup black beans (drained) and 1 tsp cumin to the batter for a Tex-Mex twist. Top with ½ cup salsa after baking. This version pairs perfectly with taco night!

Frequently Asked Questions
Can I use fresh or frozen corn instead?
Fresh corn works but needs 6-8 cups of kernels. Frozen is trickier—thaw and drain very well first to avoid a watery texture. Canned remains the easiest for consistent results.
Why did my casserole turn out dense?
Overmixing the batter or using too much flour can cause this. Stick to the ¼ cup flour and mix just until combined. Also ensure your eggs are at room temperature for best rise.
How do I know when it’s done baking?
Look for a golden brown top and edges pulling from the dish. A toothpick inserted in the center should come out clean or with just a few moist crumbs after 45-50 minutes.
Can I make this ahead of time?
Yes! Prepare the batter, cover tightly, and refrigerate for up to 24 hours before baking. Add 5-10 minutes to the baking time if starting cold. It’s perfect for stress-free entertaining.
