Step-by-Step Cooking Instructions

Follow these simple steps to create a delicious Slow Cooker Corn Casserole:
- Prepare the Slow Cooker: Lightly grease the inside of your slow cooker with non-stick cooking spray or a small amount of butter.
- Mix Ingredients: In a large bowl, combine the drained whole kernel corn, creamed corn, sour cream, melted butter, beaten eggs, and Jiffy corn muffin mix. Mix until well blended.
- Add Cheese and Seasoning: Stir in the shredded cheddar cheese, salt, and black pepper. If using sugar for a sweeter casserole, add it to the mixture at this stage.
- Pour into Slow Cooker: Transfer the mixture into the prepared slow cooker, spreading it out evenly.
- Cook: Cover and cook on low for 3-4 hours or on high for 2-3 hours, or until the casserole is set in the middle and the edges are golden brown.
- Check for Doneness: Insert a toothpick into the center of the casserole. If it comes out clean, the casserole is ready.
- Rest: Let the casserole sit for about 10-15 minutes before serving to allow it to set properly.
Common Mistakes to Avoid
To ensure your Slow Cooker Corn Casserole turns out perfectly every time, avoid these common mistakes:
- Overcooking: Keep an eye on the cooking time, especially towards the end. Overcooking can make the casserole dry.
- Uneven Mixing: Make sure all ingredients are thoroughly mixed to avoid pockets of dry corn muffin mix.
- Using the Wrong Cheese: While any cheese can technically be used, stick to cheeses that melt well and complement the flavors, such as cheddar or Monterey Jack.
- Skipping the Grease: Don’t forget to grease the slow cooker. This helps prevent the casserole from sticking and makes cleanup easier.
