Mashed Potato Bake with Mozzarella

My Mashed Potato Bake is packed with flavor!  Mozzarella, Parmesan, garlic and creamy potatoes make this a flavorful twist on a comfort food classic.

If someone told me I had to choose five foods to eat exclusively for the rest of my life, I really don’t know what four of my choices would be.

But I do know that one of those five foods would be potatoes.

Doesn’t sound very exciting, but potatoes are just too versatile—and delicious in every way I’ve ever tried them—to not choose as a food I quite literally couldn’t live without.

Mashed Potato Bake: A Twist on a Classic!

One of my favorite ways to prepare potatoes is the good old classic, mashed potatoes.

As an adult, I’ve come to enjoy baked mashed potatoes more than simply mashed potatoes, thanks in large part to my mom!  She has an excellent mashed potato bake recipe that is always my favorite dish in any meal it’s part of.  Her baked mashed potatoes are insanely good!

Mashed Potato Bake with Mozzarella

The dish I’m sharing today is my unique twist on both classic mashed potatoes, and baked mashed potatoes.  My decadent mashed potato bake is filled with flavor from mozzarella, Parmesan, and garlic.  And because I find Yukon Gold potatoes to be particularly creamy, that’s what I always use in this recipe.

The best part about using mozzarella here is that the top of the potatoes crisps up and browns by the end of baking.  The mozzarella also gives this potato bake a nice amount of structure.  It’s sort of like a Dutch egg pancake, but with potatoes.

Best of both worlds in my book. !!!!

Make this Mashed Potato Bake!

So next time the mashed potato craving hits you, make my Mashed Potato Bake with Mozzarella.  Pair with my Tuscan Veggie Sausage and Grapes, or whatever protein you’ve got on had for a delicious and filling meal.

A Few Things!

You can make the potato mixture the day before, or the morning before, you plan to bake the dish.  Super convenient  for busy weeknights!  Just make the potato mixture, and store covered overnight/during the day in the fridge until you’re ready to bake the potatoes.   So easy. (Spreading the potato mixture into the baking dish will be easier if you give it about 10-15 minutes to come to room temperature.)

My Favorite Offset Spatula

An offset spatula is the only tool I use for dishes like this that require spreading a mixture evenly into a baking dish.  You won’t believe how easy an offset spatula makes this step until you try it!  Here is my favorite offset spatula on Amazon [aff. link].  Give an offset spatula a try, and I guarantee you’ll find yourself using it everyday.  I certainly do!

  • 3 pounds Yukon Gold Potatoes, peeled and quartered (or cut to about 1 ½ inch by 1 ½ inch pieces)
  • 3 garlic cloves, minced
  • 3 Tbsp butter, cut into small cubes
  • 1 tsp sea salt
  • 1 cup milk
  • 1 cup mozzarella, freshly grated
  • ½ cup Parmesan, freshly grated
  • Parsley, to garnish


Boil the potatoes

  • Peel the potatoes and cut them into halves or quarters (about 1 ½ inch by 1 ½ inch pieces; this will help the potatoes cook faster.)
  • Put the potatoes in a large pot, and fill with water until the water covers the potatoes by 2 inches. Bring the water to a boil over high heat.
  • Boil the potatoes for 10-15 minutes, until when you prick the potatoes with a fork, they basically fall apart. Adjust the heat as needed during boiling to keep the water from bubbling out of the pot.

Prepare the rest of the ingredients

  • While the potatoes boil, prep all of your other ingredients—grate the cheese, cube the butter, dice the garlic.

Put it all together

  • Drain the potatoes, and place them back in the boiling pot. Add the garlic, butter, sea salt, milk, mozzarella, and Parmesan.
  • With a hand held mixer, beat all the ingredients together, until everything is completely incorporated and smooth. (You can also do this in a stand mixer if you've got one.)
  • At this point, you can go ahead and bake the potatoes, or you could refrigerate the potatoes until you are ready to bake them the next day.

Bake the potatoes

  • Preheat the oven to 375 degrees.
  • Oil an 8x8 inch pan, and add the potato mixture to the pan. With your offset spatula, spread the potato mixture evenly into the pan. You can spread the top smoothly with your spatula, or make some texture. (I kind of do little waves.)
  • Bake at 375 degrees for 35-40 minutes, until the top of the potatoes has puffed up a bit and turned a golden brown.

Serve and enjoy!

  • Remove the potatoes from the oven from oven, and let cool for at least 20-30 minutes before serving. (The longer the potatoes cool, the better each serving will retain its shape.)
  • Garnish the top of the dish with chopped parsley, if desired, and serve!


 This mashed potato bake is great with some Gardein and my Sautéed Garbanzo Beans and Spinach.  
This dish can be made ahead up to the baking part—so you can make the potato mixture, put it in the fridge, and then bake it the next day.
This dish is vegetarian and gluten-free.

    This is truly beautiful. I’ve decided i really like potatoes. But this didn’t happen until recently. So strange. Maybe I’m starting to like carbs more. I have no idea! This is perfect for a holiday meal!

      Haha that’s awesome! Potatoes are so incredibly versatile, I don’t know what I’d do without them. 😋

    Shannon, mine would be potatoes, rice, wheat, tomatoes, and bacon. But, potatoes would be my first choice. I love them cooked any way, but made into your mashed potato bake sounds like it’ll be right there on the top.

      Ohhh those are some excellent choices Ron, I’d probably choose much the same! Thanks so much! I am so with you, I don’t think I’ve ever had a potato dish I didn’t enjoy. 😋

    I would absolutely include potatoes in my list, too! There are so many fun ways to prepare them. I have to admit that I’ve never made a mashed potato bake before, though. This sounds kinda like the inside of twice-baked potatoes. I’m pretty sure it would be a HUGE hit here – yum!

      Thanks David! Potatoes are literally the BEST. 😋. And now you’ve got me craving twice-baked potatoes!! 😄
