    What Does It Taste Like?

    Crock Pot Corn Casserole is moist, creamy, and a little dense, somewhere between cornbread and corn pudding. It's creamier than cornbread but firmer than traditional corn pudding.

    It is both sweet and savory. The sweetness comes from the corn, sugar, and the Jiffy corn muffin mix, while the savory comes from the butter, sour cream, and seasonings. If all you need to know is one thing, then delicious best describes it!

    While the corn casserole is cooking in the crock pot, your stove and oven are free for other holiday favorites such as Southern Sweet Potato Casserole or Honey Roasted Carrots and Parsnips.

    Why You'll Love Corn Casserole

    It's a real crowd-pleaser! And you don't have to be an experienced cook to make it. Just mix everything up and let the slow cooker do most of the work, leaving you more time to prepare the rest of your meal or enjoy a little quiet time before the gang arrives!

    Key Ingredients

    Here's what you'll need to create this delectable corn casserole:

    All ingredients measured out into individual containers.

    Cream-Style Sweet Corn and Whole Kernel Corn - Using both gives you plenty of sweet corn flavor with a mix of creamy corn and whole kernels in every bite.

    Butter - Makes the casserole rich and buttery. Simple as that!

    Jiffy Corn Muffin Mix - This little box of corn muffin mix gives the casserole its cornbread flavor and helps give it that creamy-but-firm texture.

    Eggs - Help hold everything together. Be sure to beat them before adding them to the batter.

    Sour Cream - Makes the casserole extra creamy with just a little tang.

    Sugar - Adds a little extra sweetness to the corn casserole.

    Vanilla Extract - Just a little adds a touch of vanilla flavor. Use the pure stuff!

    Onion Powder - Gives you a little onion flavor without having to chop an onion!

    Ingredient Substitutions and Additions

    • You could use frozen corn instead of the whole kernel corn; but frozen corn tends to get a little gummy; that's why I prefer the canned version for this recipe.
    • Prefer your casserole less sweet? You can omit the additional sugar in the ingredient section.
    • Some people prefer Greek yogurt instead of sour cream.
    • In place of onion powder, use about ¼ cup of finely minced fresh onion.

    If you want to customize your corn casserole, consider these options:

    • Want to add cheese? If you'd like it cheesy, sprinkle some shredded cheddar over the top near the end of cooking
    • Want a spicy version? Then, I recommend my Jalapeno Corn Casserole.
    • Love Bacon? Cooked and crumbled bacon on top adds a smoky flavor. Add in the last 15 minutes of cooking.

    How to Make Crock Pot Corn Casserole

    With just a little prep work, you to set it and forget it, freeing up your time for other tasks while your delicious casserole cooks to perfection.

    Anne's Recipe Tips

    • Be sure to add half the melted butter to your crock pot to prevent sticking.
    • Don't overmix the batter; a few lumps are okay.
    • Check for doneness by inserting a toothpick; it should come out without wet batter when it's ready.
    • The cooking time in crock pots can vary depending on their size and temperature settings. Keep an eye on the casserole as it approaches the recommended cook time and adjust as needed. It's better to slightly undercook than overcook, as overcooking can lead to a dry casserole.
    • Cooking a casserole in a crock pot is different than the oven! The middle might not look set but it is, so be sure to stir the casserole before serving it!

    What Goes with Crock Pot Corn Casserole

    Crock pot corn casserole goes great with roasted turkey, cranberry sauce, my Stovetop Skillet Candied Sweet Potatoes, and Cabbage Casserole. With all those delicious holiday sides, you might need a bigger plate!

    Storing and Reheating Leftovers

    To store leftovers, place them in an airtight container in the refrigerator and use within 3 days. Check out this 18-piece set of glass food storage containers with locking lids from Bayco, (affiliate link) available now on Amazon.

    Leftover corn casserole can be reheated in the microwave or oven until heated through. If it's a bit dry, you can sprinkle a little water on top before reheating to add moisture.

    Crock Pot Tips

    • Use the right size crock pot. A 4- to 6-quart crock pot works well for this recipe. A smaller one may overflow, while a larger one can affect how evenly the casserole cooks.
    • Keep the lid on! I know it's tempting to peek, but every time you lift the lid, heat escapes and can add to the cooking time.

    Crock Pot Corn Casserole FAQs

    Do you drain the corn before making corn casserole?

    Yes! Drain the whole kernel corn before adding it to the batter, but don't drain the creamed corn. You need that creamy goodness!

    What's the difference between corn casserole and corn pudding?

    Corn casserole is generally firmer because it contains corn muffin mix. Corn pudding tends to be softer and more custard-like. My Crock Pot Corn Casserole falls somewhere in between ...sweet, creamy and just firm enough to scoop onto your plate.

    Why is my Crock Pot Corn Casserole mushy?

    Corn casserole is supposed to be moist and creamy, but it shouldn't contain uncooked batter. If the middle is still wet, it may need more cooking time. Remember that crock pots cook differently, so check for doneness rather than relying entirely on the clock.

    Equipment

    • crock pot (slow cooker)
    • measuring cup(s)
    • measuring spoons

    Ingredients

    • ½ cup butter, divided and melted
    • 14.75 ounces can of cream style sweet corn
    • 15.25 ounces can of whole kernel corn, drained
    • 8.5 ounces Jiffy corn muffin mix (comes in a small box)
    • 2 eggs, beaten
    • 8 ounces sour cream
    • ¼ cup sugar
    • 1 teaspoon vanilla extract
    • ½ teaspoon onion powder
    • ¼ teaspoon black pepper

    Instructions

    • Coat the bottom of your crock pot with ¼ cup of the melted butter.
    • In a large bowl, mix together the remaining melted butter, cream corn, whole kernel corn, Jiffy corn muffin mix, eggs, sour cream, sugar, vanilla extract, onion powder, and black pepper. Tip: a whisk works well for this step.
    • Pour the mixture into your crock pot/slow cooker (I use a 6-quart capacity). Do not stir but do make sure the batter is evenly spread out.
    • Put the lid on and cook on high for 2-½ hours or until the edges are browned and the center is soft set. Add an additional 15 minutes if the center isn't quite set, however, it's common for the center to be a little soft. Stir the casserole before serving.

    Notes

    • Butter the crock pot first. Pour half the melted butter into the bottom before adding the batter. This helps prevent sticking.
    • Don't overmix! Stir just until everything is combined. A few lumps are perfectly fine.
    • Keep that lid on. I know it's tempting to peek, but lifting the lid lets heat escape and can add to your cooking time.
    • Start checking a little early. Crock pots cook differently, and you don't want to end up with dry corn casserole. The toothpick shouldn't have wet batter on it, but remember that this casserole is supposed to be creamy.
    • Give it a good stir before serving. The middle may look a little soft even when the casserole is done. Stir everything together before scooping it onto everyone's plates.
