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 your Garlic Butter Scalloped Sweet Potatoes will cook evenly and develop a beautifully golden top. While the oven warms up, gather your ingredients and equipment, including a large mixing bowl and a 9×13-inch baking dish.
Step 2: Prepare the Cream Mixture
In a mixing bowl, combine your heavy cream and cornstarch. Whisk them together until the cornstarch is fully dissolved and the mixture is smooth. Next, stir in the melted butter, minced garlic, fresh thyme, and a pinch of salt and pepper. This creamy concoction will be the luscious sauce that brings the sweet potatoes to life.
Step 3: Slice the Sweet Potatoes
Peel and thinly slice your sweet potatoes into 1/8-inch rounds, using a sharp knife or mandoline for precision. To prevent browning, pour a little of the cream mixture over the slices as you go. This also ensures that each slice is nicely coated in the sauce when layered, enhancing the overall flavor of the dish.
Step 4: Layer the Potatoes
In your prepared baking dish, lay out a layer of sweet potato slices, slightly overlapping them. Drizzle some of the cream mixture over this layer, allowing it to seep in and start softening the potatoes. Continue this process, alternating layers of sweet potatoes and cream mixture until all the slices are arranged beautifully.
Step 5: Add the Final Cream
Once your sweet potatoes are all layered in the dish, pour the remaining cream mixture over the top. Make sure it covers the potatoes completely, allowing every slice to soak in the rich flavors. This will create that irresistible creaminess as it bakes and bubbles away in the oven.
Step 6: Bake the Dish
Slide the baking dish into your preheated oven and bake for 30 minutes. The sweet potatoes should start to soften and the cream should be bubbling around the edges. Keep an eye on it, as you want the top to set but not burn before adding the cheese.
Step 7: Add Cheese and Continue Baking
After 30 minutes, remove the dish from the oven and sprinkle the shredded Parmesan cheese evenly across the top. This addition will create a delightful crispy crust. Return the dish to the oven and bake for another 10 minutes, or until the cheese is golden and the sweet potatoes are fork-tender.
Step 8: Serve Warm
Once baked to perfection, remove your Garlic Butter Scalloped Sweet Potatoes from the oven. Let them cool for a few minutes before serving. This comforting dish is best enjoyed warm, showcasing its creamy texture and melt-in-your-mouth flavors.
