Loaded Mashed Potato Casserole

Want to take your Mashed Potatoes up a notch this Thanksgiving?! Then you have to give my Loaded Mashed Potatoes a try! This casserole is the BEST way to prepare baked potatoes to feed a crowd (and with no peels in sight). Enter this delicious and easy Loaded Mashed Potato Casserole. (Well, I call it a casserole because it’s baked in a casserole dish, but it’s just all the components of a baked potato minus the peels.) Fluffy white potatoes meet all of the classic baked potato toppings like butter, crumbled bacon, sharp cheddar cheese, sour cream, salt, and freshly cracked pepper. YUM! I didn’t think mashed potatoes could get any better until now! Take it up a notch with additional mix-ins like chopped green onions, pickled red onions, diced jalapeños, or chopped fresh parsley. However you serve these Loaded Mashed Potatoes, you can’t go wrong!

Ingredients for Loaded Mashed Potato Casserole

Russet Potatoes: Russet potatoes make the fluffiest mashed potatoes, so stick with russet for this recipe! You will want to peel them and cube them into smaller pieces. Bay Leaf: Bay leaf is added to the boiling water with the potatoes for added flavor. Butter: I use unsalted butter in my mashed potatoes. If you have salted, decrease the added salt you use. Sour Cream: I add sour cream to my mashed potatoes in addition to the milk and butter and it is also great to use as a topping. Milk: Milk will make the mashed potatoes smooth and fluffy! Bacon: These wouldn’t be loaded mashed potatoes without crispy bacon bits on top! Cook the bacon prior to putting it on top of the casserole. Shredded Cheese: I use shredded cheddar cheese spread on top before I pop it into the oven. Salt & Pepper: Add salt and freshly cracked black pepper to taste.

Additionally, you could mix in or top this Baked Potato Casserole with shredded barbecue chicken or pork, a heavy drizzling of barbecue sauce, chopped green onions or chives, pickled red onions, diced jalapeños, or chopped fresh parsley. You can truly customize this dish however you would customize a classic baked potato!

How To Make Loaded Mashed Potatoes

Prep: Preheat oven to 375 degrees. Grease a 9 x 13 pan with nonstick cooking spray. Meanwhile, peel and cut potatoes into large chunks. Add the potatoes to a large pot along with the bay leaf and fill with cold water. Sprinkle with salt and bring to a boil. Cook for 15-20 minutes or until the potatoes are fork tender. Drain potatoes, and transfer back to the pot. Discard the bay leaf.

Make the Mashed Potato Base Layer: Add the softened butter, and mash the potatoes until smooth (meaning lump free). Add the sour cream and milk, and continue mashing until the potatoes are smooth and fluffy. Season with salt and pepper to taste. Layer potatoes into the bottom of the prepared pan, but be careful to not pack them in (which would reduce their fluffiness).

Add the Toppings: Top with shredded cheddar cheese. (Reserve remaining toppings until the Loaded Mashed Potato Casserole is done baking). Bake: For 10 minutes or until the cheese is melted and starts to brown. If you cheese does not brown you can also turn on the broiler for a minute or so. Garnish: Top with crumbled bacon and fresh chopped parsley, and serve. Enjoy!

Tips and Tricks

Don’t over mash your potatoes: While you want your potatoes to be smooth, over mashing can lead to gluey potatoes. So try not to go overboard! To peel vs not to peel? For the best texture I recommend peeling your potatoes first! However to save on time you can scrub them really well and boil them with the skin on. Sub half the potatoes with cauliflower: If you are worried about the amount of calories in this recipe, substitute half of your potatoes with cauliflower. Just boil the cauliflower until fork tender and blend them in a food processor and mix with the rest of the potatoes. Make in advance: Make this casserole in advance by assembling the casserole and then baking when you are ready to eat! Make it your own: So many fun variations can be used with this casserole. Add different herbs like chives and thyme, or even top with some black olives or beans!
