Step‑by‑Step Instructions for Garlic Butter Sweet Potato Bake
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms up, prepare a 9×13-inch baking dish by greasing it lightly with butter or non-stick spray. This will ensure your Garlic Butter Sweet Potato Bake comes out easily and retains its delicious texture.
Step 2: Make the Cream Mixture
In a medium saucepan over medium-low heat, whisk together cornstarch and heavy cream until smooth. Add unsalted butter, minced garlic, fresh thyme, kosher salt, and pepper. Stir gently for about 5 minutes until the mixture is hot but avoid boiling. The aroma of garlic will fill your kitchen, creating a delightful foundation for your bake.
Step 3: Prepare the Sweet Potatoes
Carefully peel the sweet potatoes and slice them into uniform 1/8-inch rounds using a sharp knife or mandoline for consistency. This even cutting ensures that your sweet potatoes cook uniformly throughout the baking process, yielding tender bites enveloped in creamy goodness.
Step 4: Layer the Sweet Potatoes
Arrange half of the sweet potato rounds in the bottom of your prepared baking dish. Season this layer with kosher salt and pepper before adding the remaining sweet potatoes on top. Layering the sweet potatoes evenly is essential for creating a harmonious blend of flavor in your Garlic Butter Sweet Potato Bake.
Step 5: Add the Cream Mixture
Pour the prepared garlic-infused cream mixture evenly over the layered sweet potatoes. Use a spatula to gently spread and ensure that all the potatoes are well-coated. This creamy layer is key to achieving that luxurious texture and rich flavor profile in your dish.
Step 6: Bake the Dish Covered
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 30 minutes. This initial steaming step is crucial for tenderizing the sweet potatoes, allowing them to absorb all the aromatic flavors from the garlic butter.
Step 7: Add the Topping and Brown
After 30 minutes, carefully remove the foil, and sprinkle a generous layer of grated Parmesan cheese evenly over the top. Return the dish to the oven for another 10 minutes. This final bake allows the cheese to melt and turn golden, enhancing the overall appeal of your Garlic Butter Sweet Potato Bake.
Step 8: Optional Broil for Crispiness
For an extra layer of deliciousness, consider broiling the bake for the last 1-2 minutes. Keep a close eye on it to avoid burning; you want the cheese to achieve that perfect crispy, bubbly finish.
Step 9: Rest Before Serving
Once out of the oven, let the Garlic Butter Sweet Potato Bake rest for 10 minutes. This allows the flavors to settle, making it easier to serve and more enjoyable to eat. Pair it with your favorite protein or salad for a comforting meal.
