Easy Cheesy Casserole

This meal is quick to make and we love it because it is not heavily dressed.

A bit of sour cream and ranch and ranch dressing is flavored even further with our favorite seasonings.

This is the perfect recipe to use up leftovers in your fridge. Swap in leftover chicken, roast turkey, or even cubes of ham. Have extra roasted veggies or steamed broccoli? Add ’em in!

POTATOES Baby potatoes with their skins on means no peeling and extra quick prep. Any type of potato works well in a casserole, even sweet potatoes are an option!

MEAT Crispy bacon can be made ahead in the oven and crumbled. Use leftover or even rotisserie chicken to make this quick. Or try boiling the chicken, it’s fast & turns out flavorful every time.

SAUCE This casserole is flavorful without being too saucy. Sour cream and cheese make this casserole flavorful and we add in our favorite seasonings.

  1. I changed it a bit. I added a lot of yellow onions and cooked the onions with the potatoes until they were almost done then added bacon bits. After all was cooked I re-added the cooked chicken. and stirred the sour cream with herbs into it all. I seasoned the chicken with Aleppo pepper salt and pepper and I didn’t put it in the oven I melted the cheese on top in the skillet. Next time I will add mushrooms and maybe Dijon mustard.5 stars

  2. This is so yummy! My kids wish that there was more sauce in it. Next time I think I will double the sauce but its definitely tasty!!!

  3. I used tater tots. Sauce was good, but it didn’t really leak down through the layers. A little Buffalo Sauce thrown in was amazing!!5 stars

  4. I’m making this because I LOVE potatoes with anything or anything with potatoes.
    I was just wondering how this recipe would turn out if the potatoes were mashed with all the ingredients mixed in with the potatoes ??? Maybe cut the sauce in half ???

    1. I haven’t tried it but think it would be great with mashed potatoes. I’d think you would need to add the extras that go into a mashed potato recipe or enough sour cream/ranch to ensure they’re nice and creamy.

    1. I haven’t tried it, but I would expect the cook time would remain the same. Check to make sure they are tender, and cook a few minutes longer if needed.
