Scalloped Cheesy Potatoes

1: Preheat oven to 375F.

2: Line a rimmed baking sheet with foil and grease a shallow oval or round baking dish.

3: In a large bowl, combine Cheddar cheese, gruyere cheese, heavy cream, garlic, rosemary, 1 1/4 teaspoon salt, and 1/2 teaspoon pepper.

4: Add the sliced potatoes to the bowl with the cream mixture and toss until every slice is well coated.

5: Arrange potato slices in the baking dish, sides facing up, tightly packed.

6: Pour the remaining cream mixture over the potatoes and crack some pepper on top.

7: Dot with 2 tablespoons of butter.

8: Cover the dish tightly with foil and bake for 40 minutes.

9: Remove foil and bake for 30 minutes more or until potatoes are very tender and the top is golden brown.

10: Check if a fork can effortlessly glide in the potatoes; if not, keep checking until done.
