This Herb-Infused Cheesy Potato Casserole is your go-to comfort dish, perfect for cozy dinners or family gatherings. With the earthy aroma of fresh herbs and the irresistible gooeyness of melted cheese, it’s hard to resist this savory delight.
Russet potatoes are the star here, offering a sturdy texture that holds up well during baking. Sharp cheddar cheese adds a bold, tangy flavor, while mozzarella cheese provides that melty, stretchy goodness. Sour cream and heavy cream create a rich, creamy base, while unsalted butter adds a touch of richness. The garlic adds a warm, pungent note that complements the thyme and rosemary, infusing the dish with a woodsy, aromatic depth. Salt and black pepper round out the flavors, and a sprinkle of Parmesan cheese on top provides a savory, nutty finish. Lastly, fresh parsley is used as a vibrant garnish.
This casserole pairs beautifully with a simple green salad or roasted vegetables for a balanced meal. For a heartier dinner, serve alongside baked chicken or a juicy steak. A glass of crisp white wine complements the cheesy richness wonderfully.
First off, preheat your oven to 375°F (190°C). Trust me, starting with a hot oven makes a big difference in getting that perfect bake. In a large mixing bowl, combine your sour cream, heavy cream, and melted butter. Toss in the minced garlic, thyme, rosemary, salt, and black pepper. Give it a good stir until everything is well mixed.
Now, add your thinly sliced potatoes, along with the shredded cheddar and mozzarella cheeses, into the bowl. Use your hands or a spatula to make sure the potatoes are evenly coated with that creamy, cheesy mixture. This is where the magic starts!
Transfer everything into a greased 9x13-inch baking dish, spreading it out evenly. Cover the dish with aluminum foil — not too tight, just enough to keep the steam in. Pop it into the oven for 45 minutes. This will allow the potatoes to soften and soak in all those wonderful flavors.
After 45 minutes, take off the foil and sprinkle Parmesan cheese on top. Put it back in the oven for another 15 minutes. You’re looking for a golden, bubbly finish on top. Let it cool for a good 10 minutes before garnishing with fresh parsley and serving. This wait time helps the flavors settle and makes serving easier.
