Step‑by‑Step Instructions for Garlic & Parmesan Roasted Sweet Potatoes
Step 1: Preheat the Oven
Start by preheating your oven to 400°F (200°C). While the oven heats up, line a baking sheet with parchment paper to prevent the sweet potatoes from sticking. This simple preparation step ensures that your Garlic & Parmesan Roasted Sweet Potatoes will roast evenly and develop that irresistible crispy texture.
Step 2: Prepare the Sweet Potatoes
Wash and halve the medium-sized sweet potatoes lengthwise. Using a spoon, scoop out a small amount of flesh from the center of each half to create wells for your delicious garlic and cheese mixture. This also allows the sweet potatoes to cook more evenly, enhancing their tender texture once roasted.
Step 3: Mix the Flavorful Topping
In a bowl, combine the olive oil, minced garlic, grated Parmesan cheese, dried thyme, salt, and black pepper. Stir the mixture well to combine all the ingredients, creating a flavorful coating that will enhance the sweet potatoes. This aromatic blend will give your Garlic & Parmesan Roasted Sweet Potatoes a vibrant flavor profile that tantalizes the taste buds.
Step 4: Brush the Sweet Potatoes
Generously brush the garlic and Parmesan mixture onto the cut sides of the sweet potatoes, ensuring they are well-coated. Place the prepared halves cut-side up on the lined baking sheet. This step is crucial for achieving that beautiful golden crust and maximizing flavor on your Garlic & Parmesan Roasted Sweet Potatoes as they roast in the oven.
Step 5: Roast Until Tender
Transfer the baking sheet to the preheated oven and roast the sweet potatoes for 30 to 40 minutes. They are ready when they become tender and a fork can easily pierce through them. Keep an eye on them as they roast, enjoying the intoxicating aroma filling your kitchen as the sweet potatoes caramelize beautifully.
Step 6: Prepare the Roasted Garlic
While the sweet potatoes are roasting, take the reserved garlic cloves and wrap them in a small piece of aluminum foil. Place the foil packet alongside the sweet potatoes on the baking sheet for the last 10 minutes of roasting. Roasting the garlic will mellow its sharpness and infuse your dish with a rich, aromatic flavor.
Step 7: Add Roasted Garlic & Serve
Once the sweet potatoes are cooked and fork-tender, remove both the sweet potatoes and the foil-wrapped garlic from the oven. Mash the roasted garlic with a fork and spread it onto the sweet potatoes for an extra burst of flavor. If desired, garnish with fresh parsley for a pop of color, and serve your delectable Garlic & Parmesan Roasted Sweet Potatoes hot!
