Step‑by‑Step Instructions for Garlic Butter Scalloped Sweet Potatoes

Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This ensures that your Garlic Butter Scalloped Sweet Potatoes will bake evenly and achieve that perfectly golden crust you’re after. While the oven heats up, you can prepare the cream mixture, setting the stage for a rich and creamy casserole.

Step 2: Prepare the Cream Mixture
In a small saucepan over medium heat, whisk together heavy cream and cornstarch until smooth. As the mixture begins to warm, add in the butter, minced garlic, fresh thyme, salt, and pepper. Continue to heat until the butter melts completely, and your kitchen is filled with a delightful aroma—around 5 minutes should do the trick.

Step 3: Slice the Sweet Potatoes
Peel your sweet potatoes, revealing their vibrant orange flesh, and slice them into rounds approximately 1/8-inch thick. Aim for uniform slices to ensure even cooking. If you prefer, you can use a mandoline for that perfectly consistent thickness. This step is crucial for achieving tender layers in your scalloped sweet potatoes.

Step 4: Layer the Sweet Potatoes
Grab a baking dish and start layering the sweet potato slices neatly in the bottom. Pour a little of the creamy garlic mixture over the first layer, allowing it to seep in and coat the potatoes. Continue layering the sweet potatoes and cream mixture until you’ve used all the ingredients, finishing with a layer of the cream mixture on top to ensure a luscious bake.

Step 5: Bake the Casserole
Now, place the baking dish in your preheated oven, uncovered, and let it bake for 30 minutes. During this time, the sweet potatoes will soften and soak up all that garlicky goodness. You’ll know it’s ready when the edges begin to bubble and the top layer looks slightly set.

Step 6: Add the Cheese and Final Bake
Sprinkle a generous layer of Parmesan cheese over the top of the casserole. Pop it back in the oven for an additional 10 minutes, or until the cheese is melted, bubbly, and beautifully golden brown. This final touch adds a satisfying crispy layer that perfectly complements the creamy sweet potato base.

Make Ahead Options

These Garlic Butter Scalloped Sweet Potatoes are perfect for meal prep enthusiasts looking to streamline their holiday cooking! You can assemble the casserole up to 3 days in advance; simply layer the sweet potatoes and cream mixture in your baking dish, cover it tightly with plastic wrap, and refrigerate. To maintain their quality and prevent browning, drizzle a bit of the cream mixture over the sweet potatoes as you layer. When it’s time to serve, just pop the dish in a preheated oven at 350°F (175°C) for about 20 minutes or until heated through. Finish by sprinkling the Parmesan cheese and baking until golden and bubbly for a dish that feels fresh and indulgent, just like when you made it!

What’s the best way to store leftover scalloped sweet potatoes?
To keep your scalloped sweet potatoes fresh, store any leftovers in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy again, reheat them in the oven covered at 350°F for about 20 minutes until warmed through. This helps retain that creamy texture!

What are some common troubleshooting tips for making scalloped sweet potatoes?
Very good question! If your sweet potatoes are too firm after baking, they may have been sliced too thick; aim for about 1/8 inch for optimal texture.
