Rosemary Parmesan Scalloped Potatoes

Follow our step-by-step guide on how to make Rosemary Parmesan Scalloped Potatoes.

1. Step 1

   Start by preheating your oven to a cozy 400°F (200°C) and give an 8-inch baking dish a light spritz of cooking spray to prevent sticking.

2. Step 2

   In a mixing bowl, combine the rich, grated Parmesan cheese with fragrant minced rosemary and zesty minced garlic, then set this delightful mixture aside for later.

3. Step 3

   Now, grab a mandolin and slice 3 or 4 red potatoes into ultra-thin rounds, while the rest can be sliced a bit thicker for added texture.

4. Step 4

   Begin layering the thin potato slices in the bottom of your prepared baking dish, overlapping them to create a beautiful base that’s about 2 to 3 slices deep.

5. Step 5

   Stand the remaining thin slices along the sides of the dish, letting them peek over the rim by about half an inch, and overlap them to form a lovely layer that’s 4 slices deep.

6. Step 6

   Next, spread one-third of the thicker potato slices over this first layer, followed by a sprinkle of one-third of your Parmesan cheese mixture.

7. Step 7

   Repeat this layering process once more for extra flavor and texture.

8. Step 8

   Finally, arrange the remaining potato slices on top and set aside one-third of the Parmesan mixture for later use.

9. Step 9

   In a saucepan over medium heat, melt some butter and whisk in flour until it’s smooth and creamy.

10. Step 10

    Gradually pour in milk, stirring constantly until the sauce thickens, which should take about 5 to 6 minutes.

11. Step 11

    Don’t forget to stir in a pinch of salt for flavor! Using a knife, create small wells in the potato layers to let the sauce seep through, then pour the creamy sauce evenly over the potatoes in the baking dish.

12. Step 12

    Top it all off with the reserved Parmesan cheese mixture and brush the edges of the exposed potato slices with a drizzle of olive oil for a golden finish.

13. Step 13

    Now, it’s time to bake your creation in the preheated oven for about 1 hour to 1 hour and 15 minutes, or until the potatoes are tender and the edges are beautifully golden and crusted.

14. Step 14

    Enjoy the wonderful aroma filling your kitchen as you await this delicious dish!.
