What Ingredients You Will Need

This creamy corn casserole recipe uses humble, easy-to-find ingredients that deliver big flavor with very little effort. Most are pantry staples, and a few swaps can make it fit just about any dietary need.

• For the casserole base:
  • 1 can (15 oz / 425 g) whole kernel corn, drained (adds bursts of sweetness and texture)
  • 1 can (15 oz / 425 g) creamed corn (for creaminess and depth)
  • 1 cup (120 g) shredded cheddar cheese (sharp or mild—sharp is my favorite for extra kick)
  • 1 cup (240 g) sour cream (full-fat for the creamiest result, but light works too)
  • 1/2 cup (115 g) unsalted butter, melted (richness and flavor—use plant-based for dairy-free)
  • 2 large eggs (room temperature for best mixing)
  • 1 box (8.5 oz / 240 g) corn muffin mix (like Jiffy—adds subtle sweetness and lift)
• Flavor boosters:
  • 2 scallions, thinly sliced (optional, but adds a pop of color and freshness)
  • 1/2 tsp salt (adjust to taste)
  • 1/4 tsp black pepper (for a mild kick)
• Optional add-ins:
  • 1/2 cup (60 g) diced roasted red peppers (for color and sweetness)
  • 1 small jalapeño, seeded and minced (for a gentle heat)
  • 1/4 cup (30 g) chopped fresh parsley (for a fresh finish)

Ingredient tips: If you’re gluten-free, swap the regular corn muffin mix for a gluten-free version—Bob’s Red Mill makes a good one. For dairy-free, use vegan butter, unsweetened plain coconut yogurt instead of sour cream, and plant-based cheddar (Violife is decent). In summer, I sometimes swap in fresh corn kernels (about 2 cups) for a slightly crunchier texture. My go-to cheddar is Tillamook or Cabot—both melt beautifully and have a rich flavor. If you want a little tang, add a tablespoon of cream cheese or Greek yogurt. Don’t be afraid to play around with what you have!

Equipment Needed

• Mixing bowls: One medium for wet ingredients, one large for combining everything.
• Whisk and spatula: A whisk works best for mixing eggs and wet ingredients; spatula is handy for folding in the cheese and corn.
• Baking dish: 9×13-inch (23×33 cm) casserole dish is ideal, but you can use two 8-inch (20 cm) square pans if needed. Glass or ceramic works best for even browning.
• Measuring cups and spoons: For accuracy—trust me, you don’t want to eyeball the muffin mix.
• Oven mitts: Because that bubbling cheese gets seriously hot.
• Optional: Cheese grater (if shredding your own cheddar), and a small knife for chopping scallions or peppers.

I’ve made this casserole in everything from a battered Pyrex to a shiny new ceramic dish—both work great. If you’re short on mixing bowls, just rinse and reuse between steps (I’ve done it more times than I care to admit). For easy cleanup, grease your baking dish well or line with parchment. If you have a dishwasher, most of these tools are safe to toss in. Budget-wise, you only need basic kitchen gear—no fancy gadgets required.

Preparation Method

1. Preheat your oven: Set to 350°F (175°C). Grease a 9×13-inch (23×33 cm) baking dish with butter or nonstick spray.
2. Combine wet ingredients: In a medium bowl, whisk together 1 cup (240 g) sour cream, 2 large eggs, and 1/2 cup (115 g) melted unsalted butter until smooth. The mixture should be creamy and pale yellow.
3. Add canned corn: Stir in one can (15 oz / 425 g) whole kernel corn (drained) and one can (15 oz / 425 g) creamed corn. Mix gently—don’t worry if it looks a little runny at this stage.
4. Mix in muffin mix: Add 1 box (8.5 oz / 240 g) corn muffin mix. Fold until just combined. The batter will thicken up and have a slight cornmeal texture—don’t overmix, or your casserole may get tough.
5. Add cheese and seasonings: Stir in 1 cup (120 g) shredded cheddar cheese, 2 sliced scallions, 1/2 tsp salt, and 1/4 tsp black pepper. If using optional add-ins (peppers, jalapeño, parsley), add them now.
6. Transfer to baking dish: Pour the mixture into your prepared baking dish. Use a spatula to smooth the top, making sure the cheese is evenly distributed. It should look thick, creamy, and studded with corn.
7. Bake: Bake uncovered for 40-45 minutes, until the edges are golden brown and the center is just set. The casserole will puff slightly and jiggle just a bit when you shake the dish. If the top browns too quickly, tent with foil for the last 10 minutes.
8. Check doneness: Insert a toothpick near the center—it should come out mostly clean, with a few moist crumbs. The surface should be golden with some crispy cheddar bits.
9. Cool slightly: Let the casserole rest for at least 10 minutes before serving. This lets it set up and makes slicing much easier (plus, the flavors meld together).

Troubleshooting tips: If your casserole is too runny, bake for an extra 5-10 minutes. If it’s dry, check your oven temp (an oven thermometer helps). Use room temperature eggs for best mixing—cold eggs can make the batter seize up. If you forget to grease your dish, just soak it overnight (I’ve been there). For a crispier top, broil for 2 minutes right at the end—just watch closely.

I usually prep everything while the oven heats up, then clean as I go. Sensory cues are key: when the top is deeply golden and the kitchen smells like a buttery corn muffin, you’re good to go!

Cooking Tips & Techniques

Here’s where years of casserole-making (and a few fails) come in handy. Getting this creamy corn casserole recipe just right isn’t tricky, but a few little details make a world of difference.

• Don’t overmix: Mix the batter until just combined. Overmixing can make the casserole dense and tough—trust me, I’ve learned this the hard way.
• Use room temp ingredients: Eggs and sour cream blend more smoothly when not straight from the fridge. If you forget, just let them sit out for 15 minutes.
• Bake uncovered: This lets the top brown and get those irresistible crispy cheddar edges. Cover only if the top is getting too dark.
• Let it rest: Giving the casserole 10 minutes to cool helps it firm up, so you get neat slices (instead of a soupy mess).
• Troubleshooting thickness: If your batter seems too thin, add 2 tablespoons (16 g) extra corn muffin mix. If it’s too thick, a splash of milk works wonders.
• Multitasking: Prep your main dish while the casserole bakes. I usually throw together a salad or set the table—it’s a good way to maximize your time.
• Cheese matters: Pre-shredded cheese is fine, but freshly grated cheddar melts smoother and tastes better. I’ve tried both (sometimes out of pure laziness), and the difference is real.

One time, I forgot to drain the corn—ended up with a slightly wetter casserole, but still delicious. If you want a firmer texture, stick with drained corn and full-fat sour cream. For consistency, always bake in a glass or ceramic dish—metal pans tend to brown too fast. Don’t stress if it cracks on top; that’s just extra crispy goodness.

Variations & Adaptations

This creamy corn casserole recipe is super flexible. Whether you need it dairy-free, gluten-free, or just want to mix up the flavors, here are some easy tweaks:

• Gluten-free: Swap the regular corn muffin mix for a certified gluten-free brand (Bob’s Red Mill or King Arthur). Everything else stays the same!
• Dairy-free: Use vegan butter, plant-based sour cream, and dairy-free cheddar. Coconut yogurt works in place of sour cream for a subtle twist.
• Spicy version: Add 1/2 cup (60 g) diced jalapeños or 1/2 teaspoon cayenne pepper for some heat. My husband loves this one, especially with barbecue chicken.
• Seasonal adaptation: Use fresh corn kernels in summer—about 2 cups (340 g). It adds a little crunch and a burst of sweetness.
• Flavor swap: Stir in 1/2 cup (60 g) crumbled bacon or cooked sausage for a breakfast casserole vibe. Sprinkle smoked paprika on top for a hint of warmth.

I tried adding diced roasted red peppers once, and it was a hit—bright color and a touch of sweetness. For allergies, skip the egg and use a flaxseed or chia seed “egg” (1 tbsp seed + 2.5 tbsp water, mixed and rested). For different cooking methods, bake in muffin tins for individual servings (great for lunchboxes!). Customize with herbs like thyme or chives if you want something fresh.

Serving & Storage Suggestions

This creamy corn casserole with cheddar tastes best fresh from the oven, but it’s just as good reheated. Here are my favorite ways to serve and store it:

• Serving temp: Warm or at room temperature—either works, but I love it piping hot with the cheese still gooey.
• Presentation: Sprinkle fresh parsley or a few extra scallions on top for color. Serve straight from the baking dish for rustic charm.
• Pairings: Goes perfectly with roasted chicken, barbecue, ham, or a simple green salad. A cold glass of sweet tea or lemonade is the classic Southern pairing.
• Storage: Cool leftovers completely, then cover and refrigerate up to 4 days. For longer storage, wrap tightly and freeze for up to 2 months—thaw overnight in the fridge.
• Reheating: Warm slices in the oven at 350°F (175°C) for 10-15 minutes, or microwave individual portions for 1-2 minutes. If reheating from frozen, add 5 extra minutes in the oven.

Honestly, the flavors get even better after a day in the fridge—the sweetness of the corn deepens, and the cheddar melds throughout. If you’re bringing it to a potluck, reheat just before serving and transport in an insulated bag.

Nutritional Information & Benefits

Here’s a quick look at what you’re getting with each serving (about 1/8th of the casserole):

• Calories: Approx. 260
• Fat: 16g
• Carbs: 23g

Corn is naturally high in fiber and antioxidants, while cheddar adds calcium and protein. Using light sour cream and reduced-fat cheese can lower calories if you want. For gluten-free or dairy-free diets, just swap the muffin mix and dairy products accordingly. The casserole contains eggs, dairy, and wheat, so skip or swap for allergies. Personally, I love how it’s filling but not heavy—a great way to sneak veggies into a picky eater’s plate!
