Instructions
1. Preheat the oven
Set the oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Prepare the potatoes
Cut the potatoes into evenly sized pieces, about 1 inch each.
3. Season them
In a bowl, toss the potatoes with olive oil, salt, black pepper, garlic powder, and oregano. Spread them out in a single layer on the baking sheet.
4. Roast
Bake for 25–30 minutes, turning the potatoes halfway through, until they’re golden brown and crisp on the outside.
5. Make the sauce
In a saucepan, melt the butter over medium heat. Add the minced garlic and cook for about 1 minute until fragrant. Whisk in the flour, then slowly add the milk and cream while stirring. Cook for 3–4 minutes, until the sauce thickens. Stir in the Parmesan cheese, salt, and pepper.
6. Combine everything
Place the roasted potatoes in a large bowl, pour the creamy sauce over them, and gently toss to coat.
7. Finish and serve
Sprinkle with fresh parsley and serve immediately while warm.
Tips for the Best Results
- Cut the potatoes evenly so they cook at the same rate.
- Avoid crowding the baking sheet—use two pans if necessary to keep them crisp.
- Turn the potatoes halfway through roasting to brown them evenly.
- Prepare the sauce while the potatoes roast so everything is ready at the same time.
- Serve immediately because the potatoes will continue to absorb the sauce as they sit.
- Consider doubling the sauce if you love extra creaminess.
