Creamy Garlic & Herb Scalloped Potatoes Casserole
Few side dishes bring warmth and richness to the dinner table like a classic **Creamy Garlic & Herb Scalloped Potatoes Casserole**. Featuring thinly sliced golden potatoes layered in a glass baking dish and drenched in a silky cream sauce infused with minced garlic, fresh parsley, and melted Parmesan, this recipe delivers decadent flavor with a perfectly tender texture in every bite.
1. Key Ingredients for a Rich & Silky Sauce
A well-balanced sauce relies on simple, fresh ingredients that thicken into a velvet coat over the potato rounds:
- Yukon Gold or Yukon Yellow Potatoes: Naturally buttery with a starch level ideal for baking without breaking down entirely.
- Heavy Cream & Whole Milk: Creates the rich, luscious base for the sauce.
- Fresh Garlic & Herbs: Freshly minced garlic cloves, chopped parsley, and a pinch of thyme infuse aromatic notes.
- Grated Parmesan & Mozzarella: Melts into the warm sauce and creates a golden, bubbly cheese top layer.
2. Step-by-Step Cooking Recipe
Ingredients List:
- 3 lbs Yukon Gold potatoes, thinly sliced (about 1/8-inch thick)
- 1.5 cups heavy cream
- 1 cup whole milk or chicken broth
- 4 cloves garlic, finely minced
- 3 tablespoons fresh flat-leaf parsley, finely chopped
- 1 teaspoon fresh thyme leaves (or 1/2 tsp dried)
- 1 cup freshly grated Parmesan cheese
- 1 cup shredded Mozzarella or Gruyère cheese
- 2 tablespoons unsalted butter
- 1 teaspoon sea salt
- 1/2 teaspoon freshly cracked black pepper
Step-by-Step Instructions:
- Preheat & Prep Dish: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch glass casserole dish with butter.
- Layer the Potatoes: Arrange sliced potatoes in overlapping, neat layers across the bottom of the prepared glass dish. Lightly season layers with salt and black pepper as you build them.
- Prepare the Herb Cream Sauce: In a mixing bowl or saucepan, whisk together heavy cream, whole milk, minced garlic, chopped parsley, thyme, grated Parmesan, salt, and pepper until combined.
- Pour over Potatoes: Slowly pour the rich herb cream sauce evenly over the layered potatoes, making sure the liquid penetrates down between the slices.
- Bake Covered: Cover the glass dish tightly with aluminum foil and bake for 45 minutes until potatoes are tender when pierced with a fork.
- Add Cheese & Brown: Remove foil, top with shredded Mozzarella cheese, and return to the oven uncovered for an additional 15 to 20 minutes until the top is bubbling and golden-brown.
- Rest & Serve: Let the casserole rest for 10–15 minutes before serving so the sauce thickens to perfection.

A: Yes. Assemble the potato layers and pour the sauce over top. Cover tightly and refrigerate overnight. Increase initial covered baking time by 10 minutes when baking directly from the fridge.
