This cheesy mashed potato casserole will be the highlight of your table during family dinners, potlucks, or festive gatherings. It is extraordinarily delightful and quite simple to prepare. Like any conventional mashed potato recipe, it begins by boiling the finest spuds and incorporating butter, milk, and seasoning. This recipe distinguishes itself by infusing fresh thyme and garlic during the boiling phase for remarkable flavor.
Once the potatoes are boiled, they are mashed using a potato ricer for the optimum fluffy and creamy texture. Then comes the cheesy goodness of sharp cheddar cheese, gruyere, and mozzarella cheese. The mixture is then seasoned to perfection and transferred to a baking dish, topped with additional cheese before being baked until flawless. This recipe is for you if you are a fan of comfort food.
You might be curious about why I didn’t include sour cream or parmesan cheese in this recipe. It doesn’t require them, and I aimed to keep it straightforward without sacrificing flavor and texture. However, feel free to incorporate any other cheeses or ingredients you prefer to personalize it. Let’s get started!

Instructions to make baked cheesy mashed potatoes
Peel the potatoes and chop them into sizable chunks of uniform size to ensure they cook uniformly. Place the diced potatoes in a large pot over high heat and fill with water, approximately 2 inches above them. Incorporate salt, fresh thyme, and garlic, and stir lightly to mix.
Preheat your oven to 400F /200C.
Lower the heat to medium-high and boil the potatoes until they are tender enough to pierce with a fork, approximately 12-15 minutes. Drain the potatoes thoroughly (discard the thyme stem) and return them to the pot. Allow them to cool while you warm the milk and butter.
Meanwhile, heat the milk and butter in a saucepan until the butter is melted. Take the pan off the heat and set aside.
Using a potato ricer, handheld masher, or electric potato masher, mash the potatoes until they are smooth and creamy.
Gradually pour in the milk and butter mixture while stirring continuously until fully blended. Next, add chopped parsley and season with salt and pepper according to your preference.
Incorporate the shredded mozzarella, gruyere, and cheddar cheese and gently fold it into the mashed potatoes.
Transfer the mashed potato blend to a casserole dish and spread the top evenly. Finally, top with additional shredded cheese.
Bake in the oven until the cheese is melted, bubbly, and golden brown, approximately 20-25 minutes. For a more golden brown crust on top, switch to broil for the last few minutes of baking.
Remove the baking dish from the oven and let it cool slightly.
Serve hot as a side dish with your favorite protein, vegetables, and gravy for a complete meal.
