Creamy Scalloped Potatoes with Parmesan and Thyme Recipe
Introduction
Creamy scalloped potatoes are a comforting classic that’s perfect for family dinners or special occasions. Thinly sliced Yukon gold potatoes are baked in a rich, garlicky cream sauce with Parmesan and thyme, resulting in a golden, cheesy dish that melts in your mouth.

Ingredients
- 5 pounds Yukon gold potatoes, thinly sliced (about 1/16 inch)
- 2 tablespoons unsalted butter
- 2 cloves garlic, minced or pressed
- 1 tablespoon all-purpose flour
- 1 cup heavy cream (or substitute with whole milk or half-and-half)
- ½ cup grated Parmesan cheese (plus more for topping)
- 1 teaspoon fresh thyme (or ½ teaspoon dried thyme)
- ½ teaspoon kosher salt
- ½ teaspoon black pepper
Instructions
- Step 1: Preheat your oven to 400°F (200°C) and lightly grease a ceramic baking dish.
- Step 2: Peel the potatoes and slice them thinly, about 1/16 inch thick, using a mandoline or sharp knife.
- Step 3: In a large pot over medium heat, melt the butter. Add the minced garlic and cook for 1 minute until fragrant.
- Step 4: Stir in the flour and cook for 1–2 minutes, forming a roux that will thicken your sauce.
- Step 5: Slowly whisk in the heavy cream, stirring constantly, and cook until the sauce thickens slightly, about 5 minutes.
- Step 6: Add the Parmesan cheese, thyme, salt, and pepper to the sauce. Stir until smooth and velvety.
- Step 7: Toss the sliced potatoes in the sauce, ensuring they are coated evenly.
- Step 8: Arrange the potatoes upright in the prepared baking dish. Pour any remaining sauce over the top and sprinkle with extra Parmesan cheese.
- Step 9: Cover the dish with foil and bake for 30 minutes.
- Step 10: Remove the foil and bake for an additional 30 minutes until the potatoes are golden and bubbling.
- Step 11: Let the scalloped potatoes rest for 10 minutes before serving to allow the sauce to set.
Tips & Variations
- Use a mandoline for uniformly thin potato slices, ensuring even cooking.
- Substitute half-and-half or whole milk for heavy cream to reduce richness if preferred.
- Add a pinch of nutmeg to the sauce for a warm, subtle spice.
- Mix in shredded Gruyère or cheddar cheese for a different cheesy flavor.
- Use fresh herbs like rosemary or sage instead of thyme for a flavor twist.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 350°F (175°C) covered with foil until warmed through, or microwave in short intervals, stirring occasionally to keep the sauce creamy.

Ingredients
Potatoes
- 5 pounds Yukon gold potatoes, thinly sliced (about 1/16 inch)
Sauce
- 2 tablespoons unsalted butter
- 2 cloves garlic, minced or pressed
- 1 tablespoon all-purpose flour
- 1 cup heavy cream (or substitute with whole milk or half-and-half)
- ½ cup grated Parmesan cheese (plus more for topping)
- 1 teaspoon fresh thyme (or ½ teaspoon dried thyme)
- ½ teaspoon kosher salt
- ½ teaspoon black pepper
Instructions
- Preheat and prepare baking dish: Preheat the oven to 400°F (200°C) and lightly grease a ceramic baking dish to prevent sticking and ensure even baking.
- Slice potatoes: Peel the Yukon gold potatoes and thinly slice them about 1/16 inch thick using a mandoline or a sharp knife to ensure even cooking and layering.
- Melt butter and cook garlic: In a large pot over medium heat, melt the unsalted butter, then add the minced or pressed garlic and cook for 1 minute to release its aroma without browning.
- Make roux: Stir in the all-purpose flour and cook for 1 to 2 minutes, stirring constantly, to form a roux that will thicken the sauce and remove the raw flour taste.
- Whisk in cream: Slowly add the heavy cream while whisking constantly to prevent lumps. Continue stirring until the mixture slightly thickens, approximately 5 minutes.
- Add seasoning and cheese: Incorporate the grated Parmesan cheese, fresh thyme, kosher salt, and black pepper into the sauce, stirring until the sauce becomes smooth and velvety.
- Coat potatoes with sauce: Toss the thinly sliced potatoes in the prepared cheese sauce to coat each slice evenly, enhancing flavor throughout.
- Arrange potatoes in dish: Place the sauced potato slices upright in the greased baking dish for an attractive presentation. Pour any remaining sauce over the top and sprinkle additional Parmesan cheese for a golden crust.
- Initial bake: Cover the baking dish with foil to retain moisture and bake in the preheated oven for 30 minutes to allow the potatoes to soften.
- Finish baking uncovered: Remove the foil and continue baking for another 30 minutes until the potatoes are tender, the top is golden brown, and the sauce is bubbling.
- Rest before serving: Let the scalloped potatoes rest for 10 minutes after baking to allow the sauce to thicken and set for easier serving and enhanced texture.
Notes
- Using Yukon gold potatoes provides a creamy texture and holds shape well during baking.
- Substitute heavy cream with whole milk or half-and-half for a lighter version but expect a less rich sauce.
- Thinly slicing the potatoes ensures even cooking and tender layers.
- Covering with foil initially helps the potatoes cook through without drying out.
- Allowing the dish to rest after baking improves sliceability and flavor melding.
