Ingredients You’ll Need
Frozen corn kernels: You’ll need 30 ounces, which is about 5 1/3 cups once thawed. Make sure to thaw them first – I like to put them in a colander and run cool water over them.
Nonfat cream cheese: A 4-ounce package works perfectly here. Let it sit out for a few minutes to soften up, which makes mixing so much easier.
Reduced-fat sour cream: Half a cup adds that lovely tangy flavor that balances the sweetness of the corn beautifully.
Low-fat milk: Just half a cup helps create that creamy texture we’re going for. Regular milk works great too if that’s what you have.
Sugar: This is totally optional! Some frozen corn is sweeter than others, so taste yours first and decide if you want that extra 1 1/2 teaspoons of sweetness.
Salt: Half a teaspoon brings out all those wonderful flavors and makes everything taste even better.
How to Make Slow-Cooker Corn Casserole

Step 1: Add all your ingredients to a 3 1/2-quart slow cooker. Don’t worry about mixing them perfectly – they’ll blend together as they cook. Cover with the lid and set to Low heat. Cook for about 4 hours, stirring once halfway through. You’ll know it’s done when everything looks creamy and well combined.
Easy and Quick Slow-Cooker Corn Casserole Version
Want to speed things up a bit? You can cook this on High for about 2 hours instead! Just keep an eye on it and stir every 45 minutes or so. The texture will be just as creamy and delicious, and you’ll have dinner ready in half the time.
Serving Ideas
This creamy corn casserole is the perfect side dish for so many meals! It goes beautifully with grilled chicken, barbecue ribs, or even a simple roast. I love serving it alongside some fresh green beans and warm dinner rolls for a complete comfort food meal.
Storage
Store any leftovers in the fridge for up to 4 days in a covered container. To reheat, just pop it in the microwave for 1-2 minutes, stirring halfway through. You can also warm it up in a saucepan over low heat, stirring gently until heated through.
Substitutions
No reduced-fat sour cream? Regular sour cream works just fine! You can also swap the low-fat milk for whole milk or even heavy cream if you want it extra rich. Greek yogurt makes a great substitute for the sour cream too – just use the same amount.
Pro Tips
- Taste your corn first: Some brands are naturally sweeter, so you might not need that optional sugar at all.
- Don’t skip the halfway stir: This helps everything blend together perfectly and prevents any sticking.
- Let the cream cheese soften: Even just 10 minutes on the counter makes mixing so much easier.
- Use a liner: Slow cooker liners make cleanup a breeze with this creamy dish.
FAQs
Can I use fresh corn instead of frozen?
You bet! Fresh corn works wonderfully in this recipe. You’ll need about 5-6 ears of corn to get the same amount. Just cut the kernels off the cob and use them exactly like you would the frozen corn.
Can I make this ahead of time?
Sure! You can mix all the ingredients together the night before and store them in the fridge. Then just dump everything in the slow cooker the next morning and cook as directed.
Will this work in a smaller slow cooker?
A 3-quart slow cooker will work just fine! Just keep an eye on it as it might cook a little faster. If you only have a larger one, no worries – it’ll still turn out great.
Can I double this recipe?
Absolutely! Just double all the ingredients and use a 6-quart slow cooker. You might need to add an extra hour to the cooking time, so check it at the 4-hour mark.
