Can we talk about this whole “Day Light Savings” thing?

I’m not liking it one bit. It’s seriously messing every thing up. Majorly.

First of all, I was supposed to get an extra hour of sleep on Sunday morning, but no… my daughter comes bursting into my room an hour earlier stating that it’s time to wake up. And guess what? That hasn’t stopped. So now I get negative one hour of sleep.

Then there is the fact that it is now freakishly dark at 5:30pm, and I’m actually losing more and more day light by the day. Where’s the savings in that??

With the lack of day light, the chances of me getting some decent photos are slim. So, I apologize for these pictures of my Slow Cooker Macaroni and Corn Casserole with their lack-luster quality… and I’m blaming whoever invented day light savings. 

Thanksgiving is just a couple weeks away so I am sharing some of my favorite holiday recipes with you. When it comes to side dishes, it’s always a juggle between the side dishes and the turkey. How and when will it all fit into your oven?!

Have no fear- I’m here to save the day! I’m going to share with you some classic side dishes that can easily be prepared in your slow cooker to free up your oven. If by chance, you’re not making a turkey in your oven and want to make this Macaroni and Corn Casserole without a crock pot, then I’ve got you covered there too! 🙂

I first made this casserole over 4 years ago for my Christmas Eve dinner. It’s a tradition I started to have a Mexican feast every Christmas Eve. I normally prepare this with the Mexican Velveeta Cheese, so it has peppers and a bit of a kick to it. For this recipe though, I left it with the plain Velveeta, but feel free to switch it up if you prefer.

What’s so simple with this Slow Cooker Macaroni and Corn Casserole is that it’s a “dump and stir” kind of recipe.

You don’t even need to pre-boil the macaroni noodles!

How much easier could it get?

Just toss it all in, give it a stir, set it to High and stir again at 45 minutes, then stir one more time after another 30 minutes.

Reduce the heat to Low for another 3 to 4 hours and you’ve got a side dish that will receive rave reviews.

My family goes nuts over this casserole.

It’s basically like macaroni and cheese that’s filled with corn. It’s so simple, yet so, so satisfying.

    I took this to a cookout this summer and it was such a hit!! Had 4-5 people ask for recipe!! I did not drain the corn and by the time I got to the cookout, the sauce was just perfect! Thank you for this recipe…it is now my go-to traveling casserole!!

    I was wondering if I could use Ragu Double Cheddar sauce in this instead of Velvetta? My boyfriend is not a big fan of Velvetta and was wondering what your thoughts were on this before I make it.

    I was curious if the cooking on low for 3-4 hours after cooking on high was necessary?
    I’m making this at work and plan to turn crockpot on at 9am but we will be eating around 1130am so I don’t have several hours to cook on low but was afraid the macaroni noodles wouldn’t be done.
    What do you recommend?

      I bake mine for 30 minutes, stir and bake another 30 minutes in the oven at 350. I make this often. You can add the extra cheese or just use the velvetta. I’m bringing mine to work tomorrow for the kids and staff.

    It doesn’t seem like there is much macaroni in the recipe compared to all of the cheese? I am wanting to make this for a work pot luck and need enough for 26 employees. I could double it but I was wondering if I could just add more noodles?

    1. You can half the recipe. I would follow the cooking instructions until you get to the last part. I think cooking on HIGH for 2 hours will suffice. If the noodles aren’t tender yet, just keep cooking until they are. Enjoy!

    I’ve never made Mac n Corn but discovered it at a friend’s party and loved it (is this a Wisconsin thing?!). I want to make it for my son’s 3rd bday party but wonder if picky toddlers will be put off by the corn. Can I make it with half the corn? One can of creamed and one can of whole? Anything else I would need to do to modify? Thanks!

    P.S. I also love your site, it’s my go-to for quick and easy family-friendly recipes. And such a cute site!

    1. Hi Amy! Thanks for your sweet comment! Yes, I think you can cut back on the corn in the recipe and it’ll work out just fine. My kids personally love the corn, but I know some kids can be picky. Hope you enjoy it and happy birthday to your little man! 🙂

  6. Susie

    P.S. – I absolutely LOVE your site. I look forward to every facebook post popping up and have used so many of your recipes.
    Thanks for all that.

  7. Emily

    Opinions please: For those who have tried both – If you bake in the oven, does it taste as good as the crockpot version? Trying to cut down on time but I LOVE this recipe and would hate to sacrifice the flavor/texture for time sake.

  8. Steph

    I was wondering if gluten free pasta would cook the same way in the crock pot? Do you think it would taste similar enough? Any other thoughts on using gluten free macaroni?

    What if I made the mistake of adding everything (shredded cheese from the beginning)? I read combine everything and turn on high to later see hold the shredded cheese to the end. The answer may not help me for Easter Sunday meal tomorrow but may help some other person who is too quick for their own good (like me). Thanks

  10. Wendy Bridstrup

    If you combine all ingredients in the beginning like it says….then you don’t have any cheese at the end to add….this is a mistake in the recipe!

  11. Becky

    I made your mac and cheese recipe for a work mac and cheese contest. I came in first place. Thanks for the wonderful recipe. I hope to add it to my Thanksgiving menu.
