The potatoes stay tender, the sauce stays creamy, and the Parmesan brings a gentle, savory edge. It’s a recipe that travels well to gatherings or sits happily on a weeknight table.

Ingredients for this Garlic Parmesan Scalloped Sweet Potatoes

Keep the ingredients simple and predictable. You’ll notice how the flavors build—garlic first, then the richness of the dairy, and finally that salty, tangy punch from Parmesan. If you prefer a lighter version, swap the heavy cream for 1% milk and a splash of cream cheese to help with creaminess.

• 2 large sweet potatoes, peeled and thinly sliced
• 2 tablespoons unsalted butter, melted
• 1 clove garlic, finely minced
• 1 cup heavy cream or half-and-half
• 1/2 cup grated Parmesan cheese
• 1/2 cup shredded mozzarella (optional for extra melt)
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1 teaspoon dried thyme or rosemary (optional)
• 2 tablespoons fresh parsley, chopped (for garnish)
• 1/4 teaspoon nutmeg (optional, a pinch)

Note: The sweet potatoes themselves bring natural sweetness and body. The garlic and Parmesan give depth, while the cream keeps everything velvety. If you’re serving this with something bright like a green salad or roasted greens, the dish will sit nicely in balance.

Instructions

1. Preheat the oven to 375°F (190°C). Lightly butter a shallow baking dish or a cast-iron skillet.
2. In a small bowl, whisk together the melted butter, minced garlic, and cream. Stir in the Parmesan, salt, pepper, and thyme. If you’re using nutmeg, add a pinch.
3. Layer half of the sliced sweet potatoes in the dish in an overlapping pattern. Pour half of the creamy sauce over them. Sprinkle half of the mozzarella if using.
4. Add the remaining sweet potatoes in a second layer. Pour the rest of the sauce over the top and sprinkle with the remaining cheese.
5. Cover the dish with foil and bake for 25 minutes. Remove the foil and bake for another 15–20 minutes, until the potatoes are tender and the top is bubbly and lightly golden.
6. If you like a crisper top, turn on the broiler for 1–2 minutes at the end, watching closely to prevent burning.
7. Let it rest for about 5 minutes before slicing. Garnish with chopped parsley and a final crack of black pepper.

Cook and Prep Times

• Prep time: 15 minutes
• Cook time: 40 minutes total
• Passive time: 5 minutes (resting after baking)

This timing assumes you’re using a standard oven and a shallow baking dish. If your slices are a touch thicker, you might need a few extra minutes. If you’re making this for a weeknight, you can slice the sweet potatoes ahead of time and store them in water to prevent browning. Just be sure to pat them dry before layering to avoid extra moisture in the dish.

Frequently asked questions

1. Can I make this ahead?

Yes. You can assemble the dish a day ahead, cover it, and refrigerate. When you’re ready to bake, increase the baking time a bit to ensure the potatoes are tender all the way through. If it’s cold from the fridge, you may need an extra 10 minutes in the oven.

2. What if I don’t have heavy cream?

You can use half-and-half with a splash of milk to loosen it, or make a light béchamel by whisking a tablespoon of flour into the melted butter, cooking for a minute, then whisking in the milk gradually. It won’t be as rich, but it will still be tasty with garlic and Parmesan.

3. Can I add other flavors?

Absolutely. A pinch of smoked paprika adds a subtle warmth. A handful of sliced shallots can be layered with the potatoes for extra sweetness. If you’d like a hint of herbes de Provence, that works nicely, too. Just don’t go overboard—the potatoes should still be the star.
