Are you guys ready for all of the holiday parties and gatherings that are approaching us? Well I am sharing with you today a side dish that will be the star of the dinner table. I couldn’t be more thrilled to partner up with Cache Valley Cheese to bring you one of the best side dishes that you will ever make!

I am all about sharing my favorite products with you that I use in my own kitchen. And Cache Valley just happens to be my favorite choice of cheese. I actually have six different kinds of cache valley cheeses stocked up in my fridge. My hubby calls me a cheese hoarder, but it would be such a tragedy to run out of cheese! Cheese can add such great flavor and a finishing touch to almost any meal and I don’t want to be without that ooey gooey cheese.

Cache Valley Cheese has been around since 1937 and they have perfected making delicious cheese using only the highest ingredients. They believe that good cheese comes from a good place and are inspired by people like us! Cache Valley Cheese is a company that I love and stand by!

Now can we just talk about a mashed potato casserole? Have you made one before? I made my first one a few years ago and they are life changing. Not only are they so convenient to be made in a casserole dish, they can be made the night before. This frees up some time in the kitchen and can easily be thrown into the oven the next day.

I promise this recipe is for the creamiest most delicious mashed potatoes you will ever eat. The addition of garlic plus the cheddar cheese! Oh my heavens. The cheddar cheese in these potatoes takes them to the next level. I mean just imagine pockets of cheddar cheese in each bite. My family couldn’t get over how incredible these were.

I love how in a mashed potato casserole the edges get slightly crisp and the inside is so tender and creamy. I don’t think I will ever make mashed potatoes any other way and I guarantee that you guys are going to love them. The flavor will absolutely blow you away and the cheddar cheese hidden inside is spectacular. Top it with some bacon and chives and you just created an amazing side dish!

This is the perfect for your next gathering and I know that it is going to be the hit at the dinner table. This is a recipe that you will want to make again and again!

  1. I’m just getting ready to make this for an early Christmas with family. Four pounds of potatoes seems like a lot but I’m going ahead. Looks delicious!

  2. This recipe looks fabulous! If I make it the night before, do I bake it then and reheat? Or bake it the next day? Thanks for your help!

  3. Made this recipe it was great…but I didn’t have sour cream bacon or chives, the family still loved it. Oh and one thing I did was put minced garlic instead of garlic salt.

  4. Lissen, this was everything. If you are reading this…simply add each of those ingredients to your shopping list and off you go. Would definately recommend making ahead and popping that pan in the oven 45 min before your guests arrive. We also used turkey bacon (of the best thickest variety, not that slippery, thin stuff) and this recipe is nothing without the green onions (chives).

  5. can’t wait to try this! if make the night before, do you recommend cooking, cooling before frig? or make, frig and cook next day?
