Creamy Parmesan Scalloped Sweet Potatoes Tips, FAQ & printable recipe

Tips for success

To achieve the most uniform cooking, try to select sweet potatoes that are similar in diameter. This makes the layering process much easier and ensures that all the slices cook at the same rate. If you find the top is browning too quickly, simply tent the dish with a piece of aluminum foil for the last 15 minutes of baking to protect the cheese while the potatoes finish cooking through.

For an extra layer of flavor, consider rubbing the inside of the baking dish with a cut clove of garlic before adding the potatoes. This subtle addition infuses the entire dish with a deeper garlic aroma.

Additionally, ensure the parmesan is freshly grated; the cellulose used in pre-shredded cheese can prevent it from melting as cleanly, which can affect the final texture of the crust you are aiming to achieve.

Variations

• Herb-Infused Cream: For a more aromatic profile, add a tablespoon of finely chopped fresh rosemary or sage to the cream mixture along with the thyme. These woody herbs complement the sweetness of the potatoes exceptionally well.
• Spiced Sweet Potato: Add a pinch of nutmeg or ground cinnamon to the cream sauce for a warmer, more festive flavor profile. This works especially well if serving the dish as part of a holiday or autumn-themed meal.

Storage and make-ahead

Fridge

Store in an airtight container in the refrigerator for up to 3 days.

Freezer

Freezing is not recommended as the cream sauce may separate and the potato texture can become grainy upon thawing.

Reheat

Reheat in a preheated oven at 350°F (175°C) until warmed through, or use a microwave for smaller portions, heating in 1-minute intervals until hot.

If you have leftovers, allow the dish to cool completely at room temperature for no more than two hours. Once cooled, cover the dish tightly with plastic wrap or transfer the contents to an airtight container.

Properly stored, the scalloped potatoes will maintain their quality in the refrigerator for up to three days. When ready to eat again, ensure the dish is reheated thoroughly before serving to restore the desired texture and temperature.

You can assemble the entire dish up to 24 hours in advance. Simply prepare the potatoes, pour over the cream mixture, and cover the dish tightly with plastic wrap. Keep it refrigerated until you are ready to bake. When it is time to cook, remove the dish from the refrigerator and let it sit on the counter for about 30 minutes to come closer to room temperature before placing it in the preheated oven.

Serving ideas

These scalloped sweet potatoes make an exceptional side dish for roasted meats, such as pork tenderloin or roast chicken. The natural sweetness of the potatoes pairs wonderfully with savory proteins, and the creamy sauce acts as a delicious accompaniment to the meal.

Serve directly from the baking dish to keep the potatoes warm, using a large serving spoon to ensure each portion includes a generous amount of the crispy parmesan crust and the creamy sauce.

For a more complete meal, consider serving alongside a fresh, crisp green salad with a bright vinaigrette. The acidity of the dressing provides a perfect contrast to the richness of the cream and the sweetness of the potatoes.

This combination creates a balanced dining experience that highlights the different textures and flavors of the meal. Whether for a holiday centerpiece or a simple family dinner, this dish is sure to be a crowd-pleasing addition to any menu.

Creamy Parmesan Scalloped Sweet Potatoes

Prep 20 minCook 45 minRest 10 minTotal 1 h 15 minServes 6

Ingredients

• 3 lbs sweet potatoes, peeled and sliced into thin rounds
• 1 1/2 cups heavy cream
• 3 cloves garlic, minced
• 1 tbsp fresh thyme leaves
• 1 cup parmesan cheese, freshly shredded

Instructions

1. Preheat the oven to 375°F (190°C). Peel the sweet potatoes and use a mandoline or sharp knife to slice them into uniform, thin rounds. Arrange the slices in the baking dish by overlapping them in neat, tight rows to ensure even cooking and a beautiful presentation.
2. In a small pitcher, combine the heavy cream, minced garlic, and fresh thyme leaves. Whisk gently to combine the flavors. Pour this mixture evenly over the arranged sweet potato slices, making sure the cream reaches between the layers to provide moisture and flavor during the baking process.
3. Sprinkle the shredded parmesan cheese over the top in a generous, uniform layer. Place the dish in the preheated oven and bake for 45 minutes, or until the potatoes are tender when pierced with a fork and the cheese crust is bubbling and golden brown. Allow to rest for 10 minutes before serving.
