Ingredients (Serves 6–8):

6 medium potatoes, peeled and thinly sliced (use a mandoline if you have one)
2 cups shredded Pepper Jack cheese
1 cup sour cream
1 cup heavy cream
2 cloves garlic, finely minced
1 tsp onion powder
½ tsp smoked paprika
Salt and freshly ground black pepper, to taste
¼ cup grated Parmesan cheese
2 tbsp melted butter
Chopped fresh parsley, for garnish (optional)

Instructions

1. Preheat Your Oven

Preheat to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or non-stick spray.

2. Make the Creamy Sauce

In a medium mixing bowl, whisk together:

Sour cream
Heavy cream
Garlic
Onion powder
Smoked paprika
Salt and pepper

This rich and flavorful mixture is what transforms plain potatoes into a luxurious casserole.

3. Layer the Casserole

Spread half of the potato slices evenly on the bottom of the baking dish.
Sprinkle half of the shredded Pepper Jack cheese over the potatoes.
Pour half of the cream mixture over the top.
Repeat the layers with the remaining potatoes, cheese, and cream.

4. Top It Off

Sprinkle the Parmesan cheese over the top.
Drizzle with melted butter for that golden, crispy finish.

5. Bake

Cover with foil and bake for 40 minutes.
Uncover and bake an additional 20 minutes, or until the potatoes are fork-tender and the top is bubbling and golden brown.

6. Rest & Serve

Let the casserole rest for 5 minutes before serving to allow the layers to set. Garnish with chopped parsley for a fresh pop of color.

Pro Tips

Want it extra spicy? Add a pinch of crushed red pepper flakes or jalapeño slices between the layers.
