Ingredients for Dad’s Creamy Cheesy Au Gratin Potatoes

4 large russet potatoes, thinly sliced
2 cups shredded sharp cheddar cheese
1 cup shredded mozzarella cheese
2 cups heavy cream
2 tablespoons unsalted butter
2 cloves garlic, minced
1 teaspoon salt
½ teaspoon black pepper
½ teaspoon paprika
1 teaspoon dried thyme or fresh thyme leaves for garnish
½ cup grated Parmesan cheese (optional for extra cheesiness)

Step 1: Prepare the Potatoes

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or nonstick spray. Wash, peel, and thinly slice the potatoes into uniform rounds, about ⅛-inch thick. This ensures even cooking and a perfectly creamy texture.

Step 2: Make the Cheese Sauce

In a saucepan over medium heat, melt the butter and sauté the minced garlic until fragrant, about 1 minute. Pour in the heavy cream, stirring continuously. Add salt, black pepper, and paprika. Once the mixture is warm (but not boiling), slowly stir in 1 ½ cups of cheddar cheese and all of the mozzarella cheese. Continue stirring until smooth and creamy.

Step 3: Assemble the Dish

Layer half of the sliced potatoes in the greased baking dish. Pour half of the cheese sauce over them, spreading evenly. Repeat with the remaining potatoes and cheese sauce, ensuring full coverage. Sprinkle the remaining ½ cup of cheddar cheese and optional Parmesan cheese on top for an extra cheesy crust.

Step 4: Bake to Perfection

Cover the dish with aluminum foil and bake for 45 minutes. Then, remove the foil and bake for another 20–25 minutes, or until the top is golden brown and bubbly. To check for doneness, insert a fork into the potatoes; they should be tender.

Step 5: Garnish and Serve

Once out of the oven, let the dish rest for 10 minutes to allow the cheese sauce to thicken. Sprinkle with dried or fresh thyme before serving. Enjoy warm alongside your favorite main dishes!

Frequently Asked Questions

1. Can I use a different type of potato?

Yes! While russet potatoes work best due to their starchy texture, Yukon Gold potatoes are also a great choice for a creamier consistency.

2. Can I make this dish ahead of time?

Absolutely! You can assemble the dish a day in advance, cover it tightly, and refrigerate. Bake it fresh when ready to serve, adding a few extra minutes to the baking time.

3. What cheese works best for this recipe?

Sharp cheddar is ideal for flavor, but you can mix it with Gruyère, Monterey Jack, or even Gouda for a unique twist.

4. How do I prevent the sauce from curdling?

Avoid boiling the cream mixture—keep it on medium heat and stir constantly to create a smooth, stable sauce.

5. Can I add other ingredients to this dish?

Yes! Bacon bits, caramelized onions, or sautéed mushrooms make great additions for extra flavor.

6. How do I make the top extra crispy?

For a crunchier topping, mix breadcrumbs with melted butter and sprinkle over the cheese before baking uncovered for the last 20 minutes.

7. Is it possible to make this dish lighter?

To lighten it up, use half-and-half instead of heavy cream and reduce the cheese slightly. It won’t be as rich, but it will still be delicious.

8. Can I reheat leftovers in the microwave?

Yes, but for best texture, reheat in the oven at 350°F (175°C) until warmed through. If using a microwave, heat in short intervals to prevent the sauce from separating.
