• 2 pounds Yukon Gold potatoes

• 2 tablespoons olive oil

• ½ teaspoon salt

• ½ teaspoon freshly ground black pepper

• ½ teaspoon paprika

For the Creamy Garlic Parmesan Sauce

• 3 tablespoons unsalted butter

• 4 garlic cloves, minced

• 2 tablespoons all-purpose flour

• 1 cup whole milk

• 1 cup heavy cream

• ¾ cup freshly grated Parmesan cheese

• ½ cup shredded mozzarella cheese

• ½ teaspoon Italian seasoning

• ½ teaspoon dried thyme

• ¼ teaspoon onion powder

• Salt and black pepper to taste

For the Topping

• ½ cup shredded mozzarella cheese

• ¼ cup grated Parmesan cheese

• 2 tablespoons fresh chopped parsley

Step-by-Step Instructions

Step 1: Prepare the Oven and Baking Dish

Preheat your oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish with butter or nonstick cooking spray.

This prevents the potatoes from sticking and makes serving easier.

Step 2: Prepare the Potatoes

Wash the Yukon Gold potatoes thoroughly.

You can leave the skins on for a rustic appearance or peel them if you prefer a smoother texture.

Slice the potatoes into approximately ¼-inch-thick rounds or half-moons.

Try to keep the slices evenly sized so they cook at the same rate.

Place the potatoes in a large mixing bowl and toss with olive oil, salt, black pepper, and paprika.

Step 3: Make the Garlic Butter Base

Place a medium saucepan over medium-low heat.

Add the unsalted butter and allow it to melt completely.

Stir in the minced garlic and cook for approximately 30–60 seconds until fragrant.

Avoid browning the garlic because it can develop a bitter taste.

Step 4: Prepare the Cream Sauce

Sprinkle the flour into the melted garlic butter.

Whisk continuously for approximately 1 minute to create a smooth roux.

Slowly pour in the milk while whisking constantly.

Add the heavy cream and continue stirring until the mixture becomes smooth.

Cook for approximately 3–5 minutes until the sauce begins to thicken.

Step 5: Add the Cheese and Seasonings

Reduce the heat to low.

Stir in the Parmesan cheese, mozzarella cheese, Italian seasoning, dried thyme, and onion powder.

Continue stirring until the cheese melts and the sauce becomes creamy.

Taste and adjust the salt and black pepper as needed.

Remove the saucepan from the heat.

Step 6: Arrange the Potatoes

Place the seasoned potato slices evenly in the prepared baking dish.

Spread them into a relatively even layer, overlapping slightly if necessary.

For the creamiest result, avoid packing the slices too tightly.

Step 7: Pour the Garlic Parmesan Sauce

Slowly pour the warm garlic Parmesan sauce over the potatoes.

Use a spatula to gently spread the sauce, ensuring it reaches between the potato slices.

The potatoes should be evenly coated so they cook in the creamy mixture.

Step 8: Cover and Bake

Cover the baking dish tightly with aluminum foil.

Place it in the preheated oven and bake for approximately 40–45 minutes.

The foil traps moisture, allowing the potatoes to soften without drying out.

Step 9: Add the Cheese Topping

Carefully remove the foil.

Sprinkle the remaining mozzarella and Parmesan cheese evenly over the potatoes.

Return the uncovered dish to the oven.

Bake for another 20–25 minutes, or until the potatoes are fork-tender and the top is golden and bubbly.

If necessary, continue baking until a knife slides easily through the center.

Step 10: Rest and Serve

Remove the baking dish from the oven.

Allow the potatoes to rest for approximately 10 minutes.

This helps the creamy sauce thicken slightly and makes serving easier.

Sprinkle with chopped parsley and optional crispy garlic bits.

Serve warm and enjoy!

Tips and Notes

1. Choose the Right Potatoes: Yukon Gold potatoes are ideal because they have a naturally buttery flavor and creamy texture. Russet potatoes also work well but may break apart more easily.

2. Slice Evenly: Uniform potato slices ensure everything cooks properly. A mandoline slicer can make preparation faster.

3. Use Fresh Garlic: Freshly minced garlic provides a stronger, more aromatic flavor than garlic powder.

4. Don’t Overheat the Cheese Sauce: Add the cheese over low heat to prevent the sauce from becoming grainy or separating.

5. Use Freshly Grated Parmesan: Fresh Parmesan generally melts more smoothly than pre-shredded varieties.

6. Cover During the First Bake: Covering the dish helps the potatoes become tender before the cheese topping browns.

7. Check for Doneness: Cooking times may vary depending on potato thickness and baking dish depth. Always check the center with a fork.

8. Make It Extra Cheesy: Add more mozzarella or a little shredded cheddar for a richer casserole.

9. Add Protein: Cooked bacon, diced ham, or shredded chicken can be added for a more filling dish.

10. Storage: Refrigerate leftovers in an airtight container for up to 3–4 days. Reheat until thoroughly hot, adding a splash of milk if the sauce has thickened.

Frequently Asked Questions

1. Can I Make Creamy Garlic Parmesan Potatoes Ahead of Time?

Yes! You can prepare and bake the casserole a day ahead. Refrigerate it after cooling, then reheat covered in the oven until thoroughly heated.

2. Can I Use Russet Potatoes Instead of Yukon Gold?

Absolutely. Russet potatoes become very soft and absorb the creamy sauce beautifully. However, they may not hold their shape as well as Yukon Gold potatoes.

3. Why Are My Potatoes Still Hard After Baking?

The potato slices may be too thick, or the baking time may have been insufficient. Cover the dish again and continue baking until the potatoes are fork-tender.

4. Can I Make This Recipe Without Heavy Cream?

Yes. Replace the heavy cream with additional whole milk for a lighter sauce. The result will be slightly less rich.

5. Can I Add Other Vegetables?

Yes! Sautéed mushrooms, cooked spinach, or caramelized onions make delicious additions. Avoid adding too many watery vegetables because they can thin the sauce.

6. How Do I Prevent the Sauce From Becoming Watery?

Use the recommended amount of flour, avoid adding excessive liquid, and allow the casserole to rest for 10 minutes after baking.

7. Can I Freeze Creamy Garlic Parmesan Potatoes?

You can freeze the baked casserole, but dairy-based sauces may separate when thawed. For the best texture, refrigerating is recommended.

8. What Can I Serve With Garlic Parmesan Potatoes?

These potatoes pair beautifully with roasted chicken, baked pork chops, grilled steak, meatloaf, or a fresh green salad.
