Step‑by‑Step Instructions for Savory Garlic Parmesan Roasted Sweet Potatoes
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C) to ensure perfect roasting conditions. A hot oven is crucial for achieving that crispy exterior on your savory garlic parmesan roasted sweet potatoes. While the oven heats up, gather your tools—prepare a large baking dish and a cutting board for the next steps.
Step 2: Prepare the Sweet Potatoes
Peel the sweet potatoes and slice them into thin, even discs, about ¼ inch thick. This helps them roast uniformly, allowing for that delightful caramelization. Arrange the slices on your cutting board, ensuring they are consistent in size for a perfect cook throughout the dish.
Step 3: Mix Ingredients in a Bag
In a large resealable bag, combine the sweet potato slices with olive oil, melted butter, minced garlic, grated parmesan, salt, pepper, and Italian seasoning. Seal the bag tightly and shake vigorously until each slice is well-coated in the savory blend. This step ensures that all the flavors intermingle beautifully with the sweet potatoes.
Step 4: Prepare the Baking Dish
Lightly butter your baking dish to prevent sticking and enhance the flavors as the sweet potatoes roast. Once coated, take a moment to visually arrange your coated sweet potato slices in a spiral pattern within the dish, overlapping slightly to create a beautiful presentation. For an extra pop of flavor, sprinkle fresh thyme on top at this stage.
Step 5: Roast the Sweet Potatoes
Now, place the baking dish in the preheated oven and roast for 30-35 minutes. Keep an eye on the sweet potatoes; they’re ready when they are tender and golden brown on the edges. A fork should easily pierce the thickest part of a slice, revealing that creamy interior under the crispy surface.
Step 6: Serve and Enjoy
Once perfectly roasted, remove the savory garlic parmesan roasted sweet potatoes from the oven and allow them to cool for a few moments. Serve warm as a delightful side dish at your next gathering or dinner, relishing in the aroma and flavors that elevate this everyday ingredient into something truly special.
