Step‑by‑Step Instructions for Garlic Butter Roasted Sweet Potatoes
Step 1: Preheat Oven
Begin by preheating your oven to 425°F (220°C). This high temperature is essential for achieving that delightful caramelization and crispy exterior on your Garlic Butter Roasted Sweet Potatoes. Allow your oven to fully heat while you prepare the sweet potatoes, ensuring they roast perfectly.
Step 2: Prepare Sweet Potatoes
Peel and cut the sweet potatoes into 1-inch uniform cubes, which helps them cook evenly. Aim for consistent sizes to avoid uneven cooking—too small pieces may burn, while larger ones might remain undercooked. Once chopped, set them aside and admire the vibrant orange color!
Step 3: Make Garlic Butter
In a saucepan, melt unsalted butter over low heat. Once melted, add the minced garlic and sauté for 1-2 minutes until fragrant, taking care not to burn it. The rich aroma of garlic blending with the butter is a sign that your garlic butter is ready to enhance the flavor of the sweet potatoes.
Step 4: Mix Ingredients
In a large mixing bowl, combine the sweet potato cubes with olive oil, salt, black pepper, smoked paprika (if using), and the melted garlic butter. Toss everything together using a spatula or your hands until the sweet potatoes are evenly coated, ensuring every piece is infused with that savory garlic flavor.
Step 5: Prepare Baking Sheet
Line a baking sheet with parchment paper or lightly grease it to prevent sticking. This step keeps your sweet potatoes from getting too soggy and allows them to roast to a beautiful golden-brown. Spread the sweet potatoes out evenly for optimal roasting.
Step 6: Spread Sweet Potatoes
Arrange the sweet potato mixture in a single layer on the baking sheet, making sure not to overcrowd them. This allows hot air to circulate, promoting even browning. If needed, use two baking sheets to provide enough space for the Garlic Butter Roasted Sweet Potatoes.
Step 7: Roast
Place the baking sheet in the preheated oven and roast for 25-30 minutes. Halfway through the cooking time, toss the sweet potatoes to ensure even browning on all sides. Look for that lovely golden color and caramelized edges, which signal that your sweet potatoes are nearing perfection.
Step 8: Check Doneness
After 25 minutes, check the sweet potatoes for doneness by piercing them with a fork. They should be fork-tender and exhibit golden-brown edges. If they need a little more time, return them to the oven, checking at 2-minute intervals to prevent overcooking.
Step 9: Add Herbs
Once done, remove the sweet potatoes from the oven and immediately sprinkle them with fresh rosemary. This adds aromatic flavors that perfectly complement the rich garlic butter. The warmth from the sweet potatoes helps release the herb’s natural oils, enhancing the overall taste.
Step 10: Garnish and Serve
Transfer the Garlic Butter Roasted Sweet Potatoes to a serving dish and garnish with fresh parsley for a pop of color and extra flavor. Serve warm as a delightful side dish to accompany your favorite entrees, and enjoy the cozy, comforting flavors they bring to your meal!

Make Ahead Options
These Garlic Butter Roasted Sweet Potatoes are perfect for meal prep enthusiasts looking to save time on busy weeknights! You can peel and cubed the sweet potatoes up to 24 hours in advance and store them in a bowl of water in the refrigerator to prevent browning. Additionally, you can prepare the garlic butter and refrigerate it for 3 days, ensuring quick assembly later. When you’re ready to serve, simply toss the sweet potato cubes with the chilled garlic butter, olive oil, salt, and pepper. Spread them on a baking sheet and roast as directed, and you’ll still achieve that delectable, warm, and crispy goodness—just as delicious as if made fresh!
