Crock Pot Corn Casserole Recipe

Ingredients

• Corn muffin mix — two boxes give you the perfect amount of cornbread base. Jiffy is the most popular and affordable brand. If corn muffin mix isn’t available where you live, try our Homemade Cornbread Mix recipe as a substitute.
• Cream-style sweet corn — creates the creamy sweet base of the casserole. Do not drain — the liquid from the cream corn is part of what makes this so incredibly creamy
• Whole kernel sweet corn, drained — adds texture and sweet corn flavor throughout. Always drain thoroughly before adding — excess liquid is the main reason corn casserole turns out runny
• Salted butter, melted — adds richness and a buttery flavor throughout. Salted butter gives the best flavor without needing to add extra salt
• Eggs, beaten — bind the casserole together and keep it tender and moist during the long slow cook. Always beat thoroughly before adding
• Sour cream — adds a subtle tang and incredible creaminess to the finished casserole. Full fat gives the richest most authentic result

How to Make Corn Casserole in Crock Pot

Step 1 – Combine Ingredients – In a large mixing bowl combine all of the ingredients. Mix thoroughly.

Step 2 – Prepare Slow Cooker – Spray crock pot with nonstick cooking spray. 

Step 3 – Add ingredients to Crock Pot – Pour batter into the prepared slow cooker.

Step 4 – Cover and cook on LOW for 6-7 hours, until the center is set and no longer jiggly. Cooking on high is not recommended — it can burn the edges before the center finishes cooking.

Step 5 – Serve and Enjoy – Dish serving onto plate and enjoy.

Tips for Success

• Place paper towels under the lid. This is the single most important tip — condensation dripping back onto the casserole makes it wet and runny. Two paper towels under the lid absorb all that moisture and give you a perfectly set creamy result
• Drain the whole kernel corn thoroughly. Excess liquid from the whole kernel corn is the number one reason corn casserole turns out runny — always drain well before adding
• Do not overmix. Stir just until everything is combined — overmixing makes the casserole dense and tough instead of light and tender
• Use a slow cooker liner. Corn casserole sticks to the slow cooker insert significantly — a liner makes serving and cleanup completely effortless especially on a busy holiday
• Switch to warm after cooking. If dinner is not ready the moment the casserole finishes switch the slow cooker to the warm setting — it will stay perfectly hot for up to 2 hours without overcooking
• Use an oval or casserole-style slow cooker if you have one. A wide, shallow shape cooks more evenly than a tall, round one, and a ceramic insert heats more gently than metal — both help prevent burnt edges with an undercooked center.

Variations and Substitutions

• Add 1 cup shredded cheddar or pepper jack cheese to the mixture for a cheesy version
• Add diced jalapeños or green chiles for a spicy kick
• Swap sour cream for softened cream cheese for an even richer creamier result
• Use fresh or frozen corn kernels instead of canned — no thawing needed for frozen
• Add ½ cup brown sugar and 1 teaspoon cinnamon to the mixture for a sweeter more dessert-style version
• Bake in a greased 9×13 dish at 350°F for 45–55 minutes if you prefer the oven method
