Our Favorite Thanksgiving Side

Since my family is a big foodie family, we always get excited about the food. I plan what recipes to make weeks in advance. I do love to cook! Of course, I have to make all my family’s favorites because, without the loaded mashed potato casserole and oven roasted turkey with homemade turkey gravy, it just doesn’t feel like Thanksgiving.

Want the best loaded mashed potato casserole recipe? You found it! I’m so excited to share my recipe with you! It truly is the perfect Thanksgiving side dish that my family is crazy about. This isn’t just any boring mashed potato recipe- they are seriously loaded with flavor!

Here’s what goes into my best loaded mashed potato casserole recipe:

Potatoes, heavy cream, bacon bits, fried onions, cream cheese, butter, shredded cheese, and salt and pepper.

  • potatoes– I like to use russet potatoes which are nice and starchy. They cook and mash well. 
  • milk– Whole milk is best and adds the most flavor.
  • butter– Lots of butter makes this dish very decadent- it is a holiday, after all!
  • sour cream and cream cheese– Sour cream and cream cheese gives the potatoes a nice tang
  • cheddar cheese– Cheese adds a yummy, salty taste.
  • bacon– You can’t go wrong with crispy, salty bacon!
  • garlic powder and pepper– You don’t need too many seasonings to make these potatoes perfect. Garlic powder and pepper add the perfect amount of spice. 
  • French fried onions– Crispy fried onions are a Thanksgiving must!

All of these ingredients are reminiscent of classic loaded baked potatoes. I have just switched it up a little and turned your favorite baked potatoes into an easy, family friendly casserole. It really may be everyone’s new favorite Thanksgiving dish.

How to Make Easy Loaded Mashed Potato Casserole

Making my loaded potato casserole recipe does take a little bit of time. However, it is not very hard to make, you just need to play in the kitchen for a little bit. Thanksgiving is all about cooking and baking!

Here is a quick look at how you make my yummy and loaded baked mashed potato casserole:

Boiling cubed potatoes in a Dutch Oven.

1. Boil the chopped potatoes until they are fork tender. Drain and discard the water.

Adding butter and cream cheese to the potatoes and mashing them together.

2. Place the cooked potatoes in a large bowl and add the milk, butter, sour cream, and cream cheese to the bowl. Smash all of the ingredients together, making the potatoes as smooth as possible. The butter, sour cream and cream cheese will melt right into the warm potatoes.

Adding shredded cheese and bacon bits to the mashed potatoes

3. Add the cheese, bacon, garlic and pepper and mix well.

Adding mashed potatoes to a casserole dish and spreading fried onions on top.

4. Spread the mashed potato mix in a casserole dish and then top with more cheese, bacon crumbles and the French fried onions. Add a little parsley for an even fancier dish.

5. Bake the casserole until the cheese on top is melted and starts to brown.

Tips and Tricks

I have made this loaded baked mashed potato casserole many times. Like I mentioned before, it is one of my family’s favorite Thanksgiving dishes – a classic in our home! Over the years, I have found a few tips and tricks that work well. Take a look before you start making your own best loaded mashed potato casserole recipe!

  • Skip the homemade mashed potatoes and use pre-made, packaged mashed potatoes. Heat the potatoes and them add all the rest of the ingredients as directed in the recipe. This is a great shortcut and will still give you an incredible dish.
  • Make the whole casserole in advance, layering the potatoes in the pan and topping them with cheese and bacon (hold off on the onions for now). Cover the casserole dish and put it in the fridge for 3-4 days. Unwrap the dish, add the onions and bake on Thanksgiving!
  • Skip the french fried onions and add extra bacon, chopped green onions or even crumbled potato chips. I also love topping the casserole with a sprinkle of breadcrumbs to give it a simple crunch.
  • Add the cooked potatoes to a stand mixer with a paddle attachment to mash them well. This will ensure your potatoes are perfectly smooth.
  • Use heavy cream in place of milk for a very decadent dish.

How To Make Ahead

You can make this up to three days ahead of time. Bake it like normal and then store it in the refrigerator sealed completely in either plastic wrap, a lid, or aluminum foil. When you’re ready to reheat it, put it in a 350F oven for 10-15 minutes or until it is heated through.
