Step‑by‑Step Instructions for Garlic Parmesan Roasted Sweet Potatoes
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature is perfect for achieving that golden-brown color on your Garlic Parmesan Roasted Sweet Potatoes. While the oven heats up, you can prepare the sweet potatoes, ensuring they’ll roast evenly and efficiently.
Step 2: Prepare the Sweet Potatoes
Peel the sweet potatoes and slice them into thin rounds, about ¼ inch thick. This ensures even cooking throughout the dish. Aim for uniform sizes to help the sweet potatoes roast beautifully. The vibrant orange color will shine once they’re roasted, promising a delightful visual treat.
Step 3: Coat the Sweet Potatoes
In a large resealable bag, combine your sweet potato slices with minced garlic, olive oil, melted butter, salt, pepper, parmesan cheese, and Italian seasoning. Seal the bag tightly and shake it well until the sweet potato slices are thoroughly coated, ensuring each slice will be infused with flavor.
Step 4: Arrange in Baking Dish
Lightly butter a baking dish to prevent sticking and to enhance flavor. Carefully arrange the coated sweet potato slices in a spiral or a single layer, making sure they are not overcrowded. Even spacing will help them roast perfectly, allowing for a delightful texture on each piece.
Step 5: Add Final Touches
If desired, sprinkle the sweet potatoes with fresh thyme and additional parmesan cheese for an extra layer of flavor just before baking. The fresh thyme will add a lovely herbal note, making your Garlic Parmesan Roasted Sweet Potatoes even more inviting when they come out of the oven.
Step 6: Roast in the Oven
Place the baking dish in the preheated oven and roast for 30 to 35 minutes. Halfway through, flip the sweet potatoes to ensure they cook evenly and achieve that crispy texture. You’ll know they’re done when they are tender and the edges are golden brown, creating an irresistible aroma.
Step 7: Serve Warm
Once cooked, remove the dish from the oven and allow the sweet potatoes to cool slightly. Serve them warm, garnished with fresh thyme for added flair. These Garlic Parmesan Roasted Sweet Potatoes not only look beautiful on the table but also bring warmth and comfort to your meal.
