Stuffed with So Much Goodness!

It’s no secret that our family LOVES potatoes, especially Mashed Potatoes. Just search “potato” here on the site and see the dozens of recipes!

Our loaded baked mashed potatoes are a must. They combine all of our favorite flavors into one delicious dish! Cheese, bacon, butter, and sour cream – what more could a potato ask for?!

We’ve taken our classic mash to new heights – a side dish perfect for holidays, dinner parties, or just because. These mashed potatoes are ALWAYS a just-because in our house!

WHY WE LOVE IT:

  • Loaded with flavor. They’re similar to our Twice Baked Potatoes but in mashed potato form.
  • A cheesy crust. Baking it in the oven gives it that deliciously cheesy melted top – our favorite part!
  • An elevated dish. This favorite potato side dish is perfect for holiday gatherings or Sunday dinners!

How to Make Baked Mashed Potatoes

  1. POTATOES. Add 8 cups water to a large pot, add 6 peeled and cubed Yukon gold potatoes, and bring to a boil. Cook for 20 minutes or until tender. Do not overboil.
    • Drain water and return the potatoes to the pot.
  2. PREP. Preheat oven to 350°F.
  3. SEASON. Add 3 tablespoons butter, ½ cup sour cream, garlic salt, and pepper to the pot and mash until smooth. Do not overmix.
  4. LAYER. Spoon half of the potatoes into a greased 8×8 pan. Cover with ½ cup of cheese and half of bacon crumbles.
    • Add the rest of the potatoes to the pan and top with the remaining cheese and bacon crumbles.
  5. BAKE. Bake for 30-35 minutes. Add fresh parsley if desired. ENJOY!

Avoid Gummy Potatoes

Overboiling and overmixing the potatoes can cause them to become thick and sticky. Mash the potatoes with an old-fashioned potato masher and then briefly mix them with a handheld electric mixer.
