Ingredients and Dietary Substitutions

- Jiffy cornbread mix: The original recipe calls for a box of Jiffy corn muffin mix. Traditional Jiffy corn mix is not gluten-free. This gluten-free version is made from scratch, without a cornbread mix, which is very easy to do and doesn't add much extra time to the entire process. Plus, it is much more cost effective than buying the gluten-free mixes from the grocery store, which all come in different sizes. This from scratch version includes:
- Gluten-free flour blend: Use a gluten-free flour blend for baking that has xanthan gum or another binder already included. I've tested this with a few different brands, such as King Arthur Measure for Measure and Bob’s Red Mill 1:1 gluten-free flour. All have worked just fine.
- Yellow Cornmeal: Look for a gluten-free yellow cornmeal or an allergen statement to make sure your cornmeal is ok for gluten-free.
- Canned Sweet Corn or whole corn kernels. Fresh corn is an option if you have it available. Cook fresh corn in the Instant Pot, or by your preferred method, then remove the kernels from the cobs before adding to the recipe.
- Canned Creamed Corn: May also be labeled cream style corn. While this corn is typically thickened with cornstarch, it is still a good idea to double-check the labels.
- Dairy-Free: Substitute Earth Balance Vegan Buttery Sticks and dairy-free sour cream.
- Egg-Free: You can eliminate the eggs in this recipe, which will result in a more creamy dish, similar to a corn pudding.
- Vegan: Follow both the dairy-free and egg-free substitutions.

Variations
This classic comfort food side dish is slightly sweet but somewhat plain in flavor, think of a corn-filled cornbread. If you'd llike to jazz it up you can try these variations!
- Cheesy corn casserole: Stir in 1 cup of grated cheddar cheese or a cheddar blend. Sprinkle some extra cheese on top of the casserole.
- Spicy: Stir two finely diced jalapeño peppers into the mix.
- Southwest: In a small pan, sauté ½ cup diced red bell pepper and ½ cup diced onion. Stir the sautéed peppers and onions along with a 4 ounce can of diced green chiles and 1 cup of shredded cheddar cheese into the mixture before baking.
- Boost of flavor: Add 1 tablespoon dried minced onion into the mixture.
- Extra sweet: Increase the sugar to ½ cup.
How to Make Cornbread Casserole

Can I make corn casserole in a slow cooker?
Yes! While traditionally you would bake this casserole in the oven, you can cook this casserole in a slow cooker or crock pot as well! Cook on high for 2 ½ hours or on low for 4 hours.
This is a great option for Thanksgiving when oven space may be limited.
How to Make Ahead
- You can mix up this casserole one day in advance.
- Cover the casserole with plastic wrap or aluminum foil and refrigerate it.
- Remove the pan from the refrigerator to bring to room temperature about 30-60 minutes before you put it in the oven.
- If the casserole is still cold, it may take some extra time to bake.
I do not recommend to bake ahead and serve the next day, this side dish is best fresh. If you are making this for Thanksgiving but don't have room in the oven, consider baking your side dishes after you remove the turkey from the oven and while the turkey rests, or cook it in the crock pot.
How to Store
Refrigerate leftover corn casserole 3-4 days or freeze for several months. Refrigerate or freeze leftovers tightly wrapped or in an airtight container. Reheat in the microwave or oven.

Made it for a baby shower and everyone loved it! I have made it 3 times now, it’s easy & delicious!
Marie
This was delicious! Wasn’t sure it needed it, but I added about 1/4 tsp. of xanthan gum since my gluten-free flour doesn’t have any. It turned out great anyway.
Marty
Doubled the recipe and did one with cheese and one without - both in smaller crockpots. Both were great and ended up being in for an additional hour (past the 4 hour low) on warm waiting for everything else to be ready and they held up perfectly. Thank you so much for a great recipe!
