What Ingredients You Will Need

This Parmesan creamed corn casserole uses simple, wholesome ingredients to deliver bold flavor and a satisfying creamy texture without any fuss. Most of these are pantry staples, and you probably already have them on hand.

• Creamed Corn: 1 can (about 14.75 oz / 417 g) – the base for creaminess and sweetness.
• Whole Kernel Corn: 1 can (about 15.25 oz / 432 g), drained – adds nice texture and pops of corn flavor.
• Parmesan Cheese: 1 cup, freshly grated – I recommend Parmigiano-Reggiano for best nutty flavor.
• Sharp Cheddar Cheese: 1 cup, shredded – adds melty, gooey richness.
• Butter: 1/4 cup (4 tablespoons / 57 g), melted – gives that luscious mouthfeel and depth.
• Sour Cream: 1/2 cup (120 ml) – for tanginess and extra creaminess (substitute with Greek yogurt if preferred).
• All-Purpose Flour: 1/4 cup (30 g) – helps thicken the casserole.
• Granulated Sugar: 1 tablespoon – balances the savory flavors perfectly.
• Garlic Powder: 1/2 teaspoon – just a hint to boost flavor without overpowering.
• Black Pepper: 1/4 teaspoon – freshly ground if possible.
• Salt: 1/2 teaspoon – adjust to taste.
• Milk: 1/2 cup (120 ml), whole or 2% – adds moisture and creaminess.

Optional but recommended:

• Chopped Fresh Parsley: 1 tablespoon for garnish – adds a pop of color and freshness.
• Panko Breadcrumbs: 1/4 cup (25 g) sprinkled on top for a crunchy finish.

If you want to make it gluten-free, swap the all-purpose flour for almond flour or a gluten-free flour blend. For a dairy-free version, try using dairy-free sour cream and a vegan Parmesan substitute—though the flavor won’t be quite the same, it still works surprisingly well.

Equipment Needed

• Baking Dish: A 9×9 inch (23×23 cm) square casserole dish works perfectly for this size recipe. I’ve also used a similarly sized glass or ceramic dish with great results.
• Mixing Bowls: One medium bowl for combining ingredients, and a small one for melting butter.
• Measuring Cups and Spoons: Accurate measurements make a difference here, especially with flour and cheese.
• Grater: For shredding fresh Parmesan and cheddar cheese. Freshly grated cheese melts better and tastes way fresher.
• Spatula or Spoon: For mixing everything together evenly.
• Oven Mitts: Essential for safely removing the hot casserole from the oven.

If you don’t have a grater, pre-shredded cheeses work fine but expect a slight difference in texture. A silicone spatula is my personal favorite because it scrapes the bowl well, minimizing waste. For budget-friendly baking dishes, glass Pyrex sets are reliable and affordable, plus easy to clean after cheesy casseroles!

Detailed Preparation Method

1. Preheat the oven to 350°F (175°C). This gives the dish a nice, even bake and ensures the cheese melts perfectly.
2. Prepare the baking dish: Lightly grease a 9×9 inch (23×23 cm) casserole dish with butter or non-stick spray to help prevent sticking.
3. Combine the corn: In a medium mixing bowl, stir together the creamed corn (14.75 oz / 417 g) and the drained whole kernel corn (15.25 oz / 432 g). This mix creates a lovely texture balance of creamy and whole kernels.
4. Add the cheeses: Stir in 1 cup of freshly grated Parmesan and 1 cup of shredded sharp cheddar cheese. The fresh Parmesan adds that signature nutty flavor, while cheddar brings gooey richness.
5. Mix wet ingredients: Melt 1/4 cup (57 g) butter in a small bowl (microwave or stovetop). To the melted butter, add 1/2 cup (120 ml) sour cream and 1/2 cup (120 ml) milk. Whisk well for a smooth blend.
6. Incorporate the dry ingredients: Add 1/4 cup (30 g) all-purpose flour, 1 tablespoon sugar, 1/2 teaspoon garlic powder, 1/4 teaspoon black pepper, and 1/2 teaspoon salt to the corn and cheese mixture. Stir gently to combine.
7. Add the wet mixture: Pour the butter, sour cream, and milk mixture into the bowl with the corn and dry ingredients. Stir everything together until well combined. The batter should be thick and creamy.
8. Transfer to baking dish: Pour the mixture into the prepared casserole dish, spreading evenly with a spatula. If you want extra crunch, sprinkle 1/4 cup (25 g) panko breadcrumbs evenly over the top.
9. Bake: Place the casserole in the preheated oven and bake for 35-40 minutes, or until the top is golden brown and the casserole is bubbling around the edges.
10. Rest before serving: Let the casserole cool for about 5 minutes once out of the oven. This helps it set nicely and makes serving easier without it falling apart.
11. Garnish: Sprinkle with freshly chopped parsley for a touch of color and freshness just before serving.

If you notice the top browning too quickly, loosely cover the casserole with foil halfway through baking. The casserole should be creamy and set, not runny, when done. If it seems too loose, an extra 5 minutes in the oven usually helps.

Cooking Tips & Techniques

In my experience, the key to this Parmesan creamed corn casserole’s success lies in balancing moisture and cheese. Too much liquid makes it runny; too little, and it dries out. That’s why measuring the milk and sour cream carefully matters.

Freshly grating the Parmesan is definitely worth the extra step. Pre-grated cheese often has anti-caking agents that can affect melting and texture.

A common mistake is skipping the flour; it might seem minor, but it’s what helps thicken the casserole so it holds together nicely. If you want a gluten-free version, just swap the all-purpose flour for a gluten-free blend with xanthan gum.

Timing is another thing I learned the hard way—don’t rush the bake! The bubbling edges and golden top are your cues that it’s ready. Pulling it out too early leaves the center too soft.

When multitasking, prep your ingredients first. Drain the corn, grate the cheeses, and melt the butter ahead of time to make mixing a breeze. I like to mix the dry ingredients separately before combining to avoid lumps.

Variations & Adaptations

• Spicy Kick: Add 1/2 teaspoon of smoked paprika or a pinch of cayenne pepper to the mix for a subtle heat that wakes up the flavors.
• Herb Lover’s: Mix in 2 tablespoons of chopped fresh herbs like thyme, chives, or basil for a fresh, garden-inspired twist.
• Low-Carb Option: Replace the flour with almond flour and use full-fat sour cream to keep it creamy without the carbs.
• Vegan Version: Swap butter for vegan margarine, use dairy-free sour cream and plant-based milk, and opt for a vegan Parmesan alternative. Keep in mind the flavor will be milder but still tasty.
• Extra Crunch: Stir in 1/2 cup cooked and crumbled bacon or toasted pecans on top for a smoky or nutty twist I sometimes do for holiday dinners.

For a seasonal twist, try adding fresh corn kernels during the summer instead of canned. Just blanch the fresh corn first, then fold it in. It adds a bright sweetness that’s unbeatable.

Serving & Storage Suggestions

This Parmesan creamed corn casserole is best served warm, straight from the oven. The gooey cheese and creamy corn are at their peak when fresh. I like to plate it alongside roasted meats or grilled veggies for a hearty, well-rounded meal.

It pairs beautifully with a crisp green salad or tangy cranberry sauce during holiday meals. For beverages, a chilled white wine or a sparkling lemonade complements the richness nicely.

To store leftovers, cover the casserole tightly with foil or plastic wrap and refrigerate for up to 3 days. Reheat gently in the oven at 325°F (163°C) for about 15-20 minutes so it warms evenly without drying out.

You can also freeze leftover portions in airtight containers for up to 2 months. Thaw overnight in the refrigerator before reheating. The flavors actually deepen after a day, so leftovers can be even better!

Nutritional Information & Benefits

One serving (about 1/6th of the casserole) offers approximately 250 calories, 15 grams of fat, 15 grams of carbohydrates, and 8 grams of protein. It’s a satisfying side that provides a good balance of fats and protein with moderate carbs.

The Parmesan cheese delivers calcium and protein, while the corn provides fiber and essential vitamins like B-complex and vitamin C. Using sour cream adds a bit of probiotic goodness too.

If you’re watching carbs or gluten, swapping flour for almond flour or gluten-free blends keeps it doable. Just be mindful if dairy is a concern—substitute with lactose-free or plant-based alternatives.

As someone who pays attention to balanced meals, I appreciate how this casserole adds creamy comfort without relying on heavy cream or processed ingredients. It’s a wholesome way to enjoy a classic side!
