Ingredients for this Cheesy Baked Mashed Potatoes

For this recipe you need simple pantry and fridge staples. I like using russet or Yukon Gold potatoes; russets give a fluffier texture while Yukon Golds are creamier. The cream cheese adds extra silkiness and a little tang that pairs nicely with sharp cheddar. Parmesan on top is optional, but it helps create a nicely browned crust.

2 lb potatoes, peeled and cut into chunks
1 cup whole milk
1/2 cup unsalted butter (1 stick), cubed
1 cup sharp cheddar cheese, shredded
1/2 cup cream cheese, softened
1 tsp salt, plus more to taste
1/2 tsp black pepper
1/4 cup grated Parmesan (optional, for topping)
2 tbsp chopped chives or green onions (optional, for garnish)

Instructions

Alright, let’s walk through it. It’s straightforward, but a few little touches make a big difference. I’ll give you notes along the way so it turns out creamy and not gluey.

Preheat the oven. Set it to 400°F (200°C). Grease a 9×9-inch baking dish or similar casserole. Easy so far.
Cook the potatoes. Place the potato chunks in a large pot and cover them with cold water by about an inch. Salt the water lightly. Bring to a boil, then simmer until tender, about 12 to 15 minutes. You want them fork-tender but not falling apart.
Drain and dry. Drain the potatoes well and return them to the warm pot for a minute to let off steam. This step helps keep the mash from becoming watery.
Mash and mix. Mash the potatoes until mostly smooth. Add the butter and cream cheese, then pour in about half the milk. Stir, then add the rest of the milk gradually until you hit the right consistency. If you like your mash silky-smooth, a ricer is great. For a homier texture, a masher is perfect.
Add cheese and season. Stir in 3/4 cup of the cheddar, plus salt and pepper. Taste and adjust seasoning. The potatoes should be flavorful enough to stand on their own; cheese brings richness, but salt is what makes it sing.
Top and bake. Transfer the mash to the prepared dish. Smooth the top and sprinkle the remaining cheddar and the Parmesan evenly over it. Bake until the cheese is melted and bubbling and the top is nicely golden, about 15 to 20 minutes. For an extra-crispy top, broil for 1 to 2 minutes—watch it closely.
Rest and serve. Let the dish rest for a few minutes after coming out of the oven. Sprinkle with chives or green onions. Serve warm.

Frequently asked questions

Can I make Cheesy Baked Mashed Potatoes ahead of time?

Yes. You can prepare the mashed potatoes up to a day ahead, store them in an oven-safe dish covered in the fridge, and bake when you’re ready. You may need to add a splash of milk when reheating if the potatoes have stiffened. For best results, bake covered for the first 10 minutes, then uncover to brown the top.

What kind of potatoes are best for mashed potatoes?

Russet potatoes give a light, fluffy texture. Yukon Golds produce a creamier, naturally buttery mash thanks to their slightly waxier starch. Both work well in this recipe. If you prefer a denser, creamier result, go with Yukon Golds.

How can I make this recipe lighter but still tasty?

Try using 2% milk or a mix of milk and low-fat sour cream instead of cream cheese, and reduce the amount of butter. You can also substitute half of the potatoes with cauliflower for a lower-carb version. Keep in mind that flavor and texture will shift slightly, but seasoning generously helps retain a satisfying taste.
