Step‑by‑Step Instructions for Scalloped Sweet Potatoes
Step 1: Preheat Your Oven
Begin by preheating your oven to 400°F (200°C). As the oven heats up, lightly grease a 2-quart baking dish with cooking spray or butter to prevent the scalloped sweet potatoes from sticking. This step sets the stage for a deliciously baked dish that is both creamy and crispy on top, ensuring a delightful contrast of textures.
Step 2: Prepare the Sweet Potatoes
While the oven is heating, take your sweet potatoes and peel them carefully. Using a mandolin or a sharp knife, slice them into thin rounds, about 1/8 inch thick. Combine all the sliced sweet potatoes in a large bowl, making sure they are evenly coated and ready to soak up the creamy sauce you’ll prepare next.
Step 3: Sauté Aromatics
In a medium saucepan over medium heat, melt 3 tablespoons of unsalted butter. Once melted, add in 2 minced garlic cloves and 1 finely chopped shallot. Sauté these aromatics for about 2-3 minutes until they become fragrant and translucent, stirring frequently to avoid burning. This flavorful base will enhance the creamy sauce for your scalloped sweet potatoes.
Step 4: Create the Creamy Sauce
Stir in 1 teaspoon of fresh thyme, and season with 1 teaspoon of kosher salt and 1/2 teaspoon of black pepper to the sautéed mixture. Gradually pour in 1 cup of heavy cream while stirring continuously, and then add 1 cup of grated parmesan cheese. Mix until the cheese is fully melted and the sauce is creamy and well-combined. This luscious sauce will envelop the sweet potatoes perfectly.
Step 5: Combine Sweet Potatoes and Sauce
Pour the creamy sauce over the bowl of sliced sweet potatoes. Gently toss to ensure each slice is coated in that irresistible mix. Then, carefully arrange the potato slices upright in the greased baking dish, layering them tightly. Make sure to pour any remaining sauce over the top for added richness before moving to the oven.
Step 6: Bake to Perfection
Place your baking dish in the preheated oven and let the scalloped sweet potatoes bake for 50-60 minutes. After about 40 minutes, check for doneness; the potatoes should be fork-tender and the top should become golden and slightly crispy. Keep an eye on it to ensure it doesn’t over-brown while developing that perfect, bubbling goodness.
Step 7: Garnish and Serve
Once baked, remove the dish from the oven and let it cool slightly for 5-10 minutes. Before serving, sprinkle a few fresh thyme leaves on top for a vibrant burst of color and flavor. Serve these creamy scalloped sweet potatoes warm, and watch them steal the show at your next festive feast!

To ensure the dish remains just as delicious, avoid combining the ingredients until you’re ready to pop it in the oven, preventing any sogginess.

How to Store and Freeze Scalloped Sweet Potatoes
• Fridge: Store leftover scalloped sweet potatoes in an airtight container for up to 3 days. Reheat in a low oven to maintain the creamy texture and crispy top.

Expert Tips for Scalloped Sweet Potatoes
• Even Slices: Ensure consistent cooking by slicing sweet potatoes evenly, preferably using a mandolin. Thicker slices may remain firm while the sauce gets too thick.
• Doneness Check: To avoid undercooked potatoes, test doneness with a fork after 50 minutes; the potatoes should be fork-tender but not mushy when making your scalloped sweet potatoes.
• Sauce Thickness: If the sauce appears too thick after combining, add a splash of extra cream. This will ensure a creamy consistency that coats the potatoes beautifully.
• Bake Time Variation: Keep in mind that oven temperatures can vary, so watch closely towards the end of baking. Adjust time based on the thickness of potato slices.
• Serving Tip: Let the dish cool for a few minutes before serving to enhance flavors and make for easier serving. Enjoy your scalloped sweet potatoes warm for the best experience!
