Plus, all of the ingredients are inexpensive, but when combined, create a hearty dish that the entire family is sure to love!

This easy corn casserole recipe uses Jiffy corn muffin mix, whole kernel corn, and cream-style corn. If you already enjoy a classic Jiffy corn casserole, this version gives you an easy way to make one in the slow cooker.

Why Make Corn Casserole in the Slow Cooker?

Oven space is often limited at Thanksgiving, with the turkey, rolls, stuffing, and other dishes all needing to bake. By making this corn casserole in the slow cooker, you free up oven space for other dishes. It’s one of the easiest slow cooker side dishes for Thanksgiving that you can make when your oven is already full, and a handy option if you want more slow cooker side dishes in your fall menu rotation.

Ingredients for Slow Cooker Corn Casserole

• 2 (15.25 oz) cans whole kernel corn, drained well
• 2 (14.75 oz) cans sweet corn cream style
• 2 (8.5 oz) boxes Jiffy corn muffin mix
• 2 cups sour cream
• 1 stick butter, melted
• 2 eggs, beaten
• ¼ cup honey

This corn casserole with Jiffy mix gets its rich, creamy texture from combining whole kernel corn with cream-style corn. The whole kernels add texture, while the cream-style corn is what gives this creamed corn casserole its soft, custardy center. The sour cream and melted butter add moisture, the Jiffy mix helps everything set as it cooks, and the honey adds a hint of sweetness.

Easy Corn Casserole Variations

This recipe is a sweet corn casserole that has a slightly sweet flavor from the ¼ cup of honey. You can swap out the honey for an equal amount of sugar, or leave out the sweetener for a more savory casserole.

For a cheesy corn casserole, leave out the honey and stir in shredded cheese before cooking. If you want a little more kick, turn it into a jalapeño corn casserole by adding diced jalapeños. You can also use diced green chiles for a milder option.

You can also mix in cooked, crumbled bacon for a more savory bacon corn casserole. Cheese, jalapeños, green chiles, and bacon can be used on their own or combined depending on what you and your guests prefer.

If you prefer not to use canned whole-kernel corn, you can use fresh or frozen corn instead. Thaw frozen corn first and drain off any excess moisture before adding it to the mixture. You can cut fresh corn from the cob and use it in place of the canned whole-kernel corn. Keep the cream-style corn in the recipe since it helps give the casserole its soft, creamy texture.

For the sweet version, you can serve it with a dollop of whipped topping, sour cream, or Greek yogurt. If you make one of the savory variations, you can serve it as is or add a little cheese, bacon, or jalapeño on top.

What To Serve With Corn Casserole This Thanksgiving

How to Store and Reheat Corn Casserole

If you have leftovers, transfer the corn casserole to a covered container and refrigerate it within two hours of cooking.

Reheat single servings in the microwave or warm a bigger portion in the oven. Make sure leftovers reach 165°F before serving. If you use the microwave, cover the casserole to help it heat evenly and stay moist.

If you won’t finish the leftovers in a few days, you can freeze them. For best quality, use frozen corn casserole within 2 to 6 months. Thaw in the fridge before reheating, or reheat straight from frozen in the oven or microwave.

Don’t reheat leftovers in the slow cooker. It’s recommended to use the oven, microwave, or stovetop instead, since slow cookers take too long to heat food safely.

Slow Cooker Corn Casserole FAQs

Can I Use Fresh or Frozen Corn Instead of Canned Corn?

Yes. You can use fresh or frozen corn in place of the canned whole-kernel corn. Thaw and drain frozen corn first so you aren’t adding extra liquid to the casserole. If you’re using fresh corn, cut the kernels from the cob before adding them.

I recommend keeping the cream-style corn in the recipe because it adds moisture and texture to the casserole.

Can I Make Corn Casserole Less Sweet?

Yes. The honey adds a bit of sweetness so you can leave it out for a more savory casserole. Try adding shredded cheese, bacon, jalapeños, or green chiles instead.

If you want the casserole to stay sweet but don’t have honey, you can use the same amount of sugar instead.

How Do I Know When Slow Cooker Corn Casserole Is Done?

Check the center with a toothpick. It should come out mostly clean without wet, raw batter.

The edges might brown before the center is done, especially on high heat, so check the middle of the casserole to see if it’s ready.

How Long Does Corn Casserole Last in the Refrigerator?

Keep leftover corn casserole in the fridge and use it within 3 to 4 days. Put leftovers in a covered, shallow container within two hours of cooking so they cool quickly.

Can You Freeze Corn Casserole?

Yes. If you won’t eat the leftovers within 3 to 4 days, you can freeze them instead. For best quality, use frozen leftovers within about 2 to 6 months.

How Do You Reheat Corn Casserole?

Reheat corn casserole in the microwave or oven until the center is 165°F. Cover it while reheating to help keep it moist.

This slow-cooker corn casserole is an easy way to add something warm and comforting to your fall or Thanksgiving meal with minimal prep.
