Ingredients

For the Potatoes

2½ lbs baby potatoes (or Yukon Gold potatoes, quartered)
3 tablespoons olive oil
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon garlic powder
1 teaspoon dried oregano (or Italian seasoning)

For the Creamy Garlic Parmesan Sauce

3 tablespoons unsalted butter
4 cloves garlic, minced
2 tablespoons all-purpose flour
1 cup whole milk
½ cup heavy cream (or half-and-half)
½ cup grated Parmesan cheese
¼ teaspoon salt (adjust to taste)
⅛ teaspoon black pepper
2 tablespoons fresh parsley, chopped (for garnish)

Kitchen Equipment Needed

Large baking sheet
Parchment paper
Mixing bowl
Medium saucepan
Whisk
Spatula or wooden spoon
Measuring cups and spoons

Instructions

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper to prevent sticking and make cleanup easier.

Step 2: Prepare the Potatoes

Wash the potatoes thoroughly. If using baby potatoes, cut them in halves or quarters so they are similar in size. For larger potatoes, cut them into 1-inch chunks to ensure even roasting.

Step 3: Season the Potatoes

In a large bowl, toss the potatoes with:

Olive oil
Salt
Black pepper
Garlic powder
Oregano

Mix well until all the potatoes are evenly coated.

Spread them in a single layer on the prepared baking sheet.

Step 4: Roast the Potatoes

Place the baking sheet in the oven and roast the potatoes for 25–30 minutes, flipping them halfway through cooking.

They should become golden brown, crispy on the outside, and tender inside.

Step 5: Prepare the Creamy Garlic Parmesan Sauce

While the potatoes roast, prepare the sauce.

Melt the butter in a medium saucepan over medium heat.
Add the minced garlic and cook for about 1 minute until fragrant.
Whisk in the flour and cook for 1–2 minutes, stirring constantly to form a smooth roux.
Slowly whisk in the milk and heavy cream until smooth.
Cook for 3–4 minutes, stirring until the sauce thickens.
Remove from heat and stir in the grated Parmesan cheese, salt, and black pepper.

The sauce should be smooth, creamy, and rich.

Step 6: Combine the Potatoes and Sauce

Transfer the roasted potatoes into a large bowl. Pour the warm garlic Parmesan sauce over them and gently toss until all the potatoes are coated.

Step 7: Garnish and Serve

Sprinkle chopped fresh parsley over the top for freshness and color. Serve immediately while warm and creamy.

Frequently Asked Questions

Can I use different types of potatoes?

Yes. Yukon Gold potatoes are ideal because they are creamy and roast beautifully. Red potatoes also work well, while Russet potatoes will be softer inside.

Can I make this recipe dairy-free?

Yes. Replace butter with olive oil, use plant-based milk, and substitute Parmesan with vegan cheese.

Why is my sauce lumpy?

This usually happens if the flour is not cooked long enough or if the milk is added too quickly. Whisk slowly and continuously while adding the liquid.

Can I add vegetables?

Absolutely! Broccoli, green beans, or asparagus can be roasted with the potatoes during the last 10–15 minutes of cooking.

Conclusion

These Creamy Garlic Parmesan Roasted Potatoes are rich, crispy, and full of comforting flavor. With perfectly roasted potatoes coated in a smooth garlic Parmesan sauce, this dish easily becomes a favorite at the dinner table.
