Essential Ingredients
The magic of this recipe relies on a simple, high quality cream sauce that blankets the potatoes as they bake.
For the Potatoes:
-
Potatoes: 3 lbs of Yukon Gold or baby yellow potatoes. Yukon Golds have a naturally buttery flavor and thin skin, meaning you don’t even have to peel them!
-
Olive Oil: 1 tablespoon to coat the baking dish.

For the Creamy Parmesan Sauce:
-
Heavy Cream: 1 cup of heavy whipping cream. (Do not substitute with milk, or the sauce will be watery and separate in the high heat of the oven!)
-
Butter: ¼ cup (½ stick) of unsalted butter, melted.
-
Parmesan Cheese: 1 cup of freshly grated Parmesan cheese. Half goes into the sauce, and the other half gets sprinkled on top for a crispy crust.
-
Garlic: 4 cloves of fresh garlic, minced.
-
Spices: 1 teaspoon of dried thyme (or Italian seasoning), 1 teaspoon of salt, and ½ teaspoon of freshly cracked black pepper.
-
Fresh Parsley: 2 tablespoons of chopped fresh parsley for a bright garnish.

Step-by-Step Instructions
Step 1: Prep the Potatoes Preheat your oven to 400°F (200°C). Grease a 9×13 inch baking dish lightly with olive oil. Wash your potatoes thoroughly. If using baby potatoes, simply cut them in half. If using larger Yukon Golds, cut them into bite sized 1 inch chunks. Place all the potato pieces into your prepared baking dish.
Step 2: Whisk the Cream Sauce In a medium bowl, whisk together the heavy cream, melted butter, minced garlic, dried thyme, salt, pepper, and ½ cup of the grated Parmesan cheese.
(Pro Tip: If you are making this for a weekend brunch, these savory potatoes are incredible when served alongside a massive Ultimate Breakfast Grilled Cheese!)
Step 3: Toss and Coat Pour the creamy garlic parmesan mixture directly over the potatoes in the baking dish. Use a large spoon or spatula to toss the potatoes until every single piece is evenly coated in the rich sauce.
Step 4: Add the Cheese Crust Spread the coated potatoes into an even layer in the dish. Sprinkle the remaining ½ cup of Parmesan cheese evenly over the top.
Step 5: Bake to Perfection Bake uncovered for 40 to 45 minutes. You want the potatoes to be fork tender and the cheese on top to be bubbly, golden brown, and slightly crispy around the edges of the pan.
Step 6: Garnish and Serve Remove the dish from the oven and let it rest for 5-10 minutes before serving. This resting time allows the cream sauce to thicken up perfectly! Garnish with fresh chopped parsley and serve warm.

Notes
Storage and Freezing Tips
To Store: Keep any leftover baked potatoes in an airtight container in the refrigerator for up to 4 days. To Reheat: The cream sauce will thicken significantly in the fridge. To reheat, add a tiny splash of milk or cream and microwave in 30 second bursts, or warm them in a 350°F oven until heated through. Leftovers are so good, they even make a brilliant side for a hearty Ultimate Breakfast Grilled Cheese the next morning! To Freeze: It is not recommended to freeze this dish. Potatoes change texture and become grainy when frozen, and the dairy based heavy cream sauce will separate and break upon thawing.
Frequently Asked Questions (FAQs)
Can I use Russet potatoes instead of Yukon Golds? Yes, but you will need to peel them first! Russet potatoes have very thick, tough skins. They are also starchier, so they may break down a bit more in the cream sauce, resulting in a slightly softer, mash like texture.
What desserts pair well with a rich dinner like this? Since these creamy potatoes are incredibly savory and rich, you will want a sweet, flavorful dessert to end the meal!

If you want something warm and cozy, a bubbling Bananas Foster Cobbler is the perfect choice.
My sauce looks a little watery when it comes out of the oven. What went wrong? This usually happens if you substitute heavy cream with whole milk or half and half. Potatoes release water as they bake, and you need the high fat content of heavy cream to bind with that moisture and create a thick sauce. Additionally, make sure you let the dish rest for 10 minutes after baking so the sauce has time to set!
