This Easy Cheesy Potatoes recipe is a beloved family heirloom passed down through generations—from my mother-in-law to her mother-in-law before her. It’s the star of nearly every family gathering, holiday dinner, and Sunday meal. The potatoes bake slowly in cream and cheese until tender, creamy, and golden on top. It’s comfort food at its finest—simple, rich, and irresistibly cheesy.
5large Idaho russet potatoespeeled and cut into ¼–½ inch thick matchsticks or cubes (matchsticks = 2 hours cook time, cubes = 1½ hours)
Salt and freshly ground black pepperto taste
2cupsheavy cream
1cupwhole milk
1teaspoononion powder
1teaspoongarlic powder
3cupsColby Jack cheesefreshly shredded and divided
Fresh parsleychopped, for garnish
Butter or nonstick sprayfor greasing the baking dish
Instructions
Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish or a large Dutch oven generously with butter or nonstick spray.
Make the cream mixture: In a medium bowl, whisk together heavy cream, whole milk, onion powder, and garlic powder until well combined. Set aside.
Layer the potatoes and cheese: Spread a layer of potatoes evenly across the bottom of the prepared dish. Season generously with salt and black pepper, then sprinkle a handful of cheese over the potatoes. Repeat layers until all potatoes are used, reserving about ½ cup of cheese for the topping.
Add the cream mixture: Pour the milk and cream mixture evenly over the layered potatoes and cheese. Gently shake or tap the dish to help the liquid distribute between layers.
Top and bake: Sprinkle the remaining ½ cup of cheese on top. Cover tightly with foil and bake for 1 hour. Remove foil and continue baking uncovered for another 45-65 minutes, until the potatoes are fork tender and the top is golden and bubbly. If you bake it in a deep casserole dish it will take longer :). If using cubed potatoes: total bake time = about 1½ hours.If using matchstick potatoes: total bake time = about 2 hours.
Rest and serve: Let the casserole rest for 10–15 minutes before serving. Garnish with fresh parsley and serve warm.
Notes
Elena's Tips:
Use freshly shredded cheese for the best creamy melt — pre-shredded cheese has anti-caking agents that can affect texture.
Salt and pepper every layer — that’s the secret to well-balanced flavor throughout.
If the top browns too quickly, tent loosely with foil near the end of baking.
Make a double batch for holidays — it disappears fast!
