Whether you’re preparing a holiday feast, a potluck contribution, or a cozy family dinner, this Crockpot Corn Casserole is simple, reliable, and irresistibly delicious.
Why Make Corn Casserole in a Crockpot?
Using a slow cooker offers several advantages:
- Frees up oven space (especially helpful during holidays)
- Ensures even, gentle cooking
- Keeps the casserole warm for serving
- Requires minimal supervision
The result is a moist, creamy casserole with golden edges and a soft, custard-like center.
Ingredients You’ll Need
Here’s what makes this dish so easy—you only need a handful of pantry staples:
- 1 can (15 oz) whole kernel corn, drained
- 1 can (15 oz) cream-style corn
- 1 box (8.5 oz) cornbread mix
- 1 cup sour cream
- ½ cup (1 stick) melted butter
- 1 cup shredded cheddar cheese (optional but recommended)
- 2 large eggs (for added structure and richness)
Optional add-ins:
- ½ teaspoon garlic powder
- ¼ teaspoon black pepper
- 2 tablespoons chopped green onions
- 1 small can diced green chilies
Step-by-Step Method
Step 1: Prepare the Crockpot
Lightly grease the inside of your slow cooker with butter or nonstick cooking spray. This prevents sticking and makes cleanup much easier later.
If you have a programmable crockpot, set it aside for now—you’ll adjust the temperature after mixing everything.
Step 2: Combine the Wet Ingredients
In a large mixing bowl:
- Add the drained whole kernel corn.
- Add the cream-style corn (do not drain).
- Stir in the sour cream.
- Pour in the melted butter.
- Crack in the eggs and whisk until fully incorporated.
Mix thoroughly so the eggs are evenly distributed. This step ensures a consistent texture throughout the casserole.
