- 2 tablespoons butter, melted: Enhances flavor depth and creates a silky coating on the slices.
- 4 tablespoons grated Parmesan cheese: Brings a salty, nutty twist that crisps up beautifully in the oven.
- 1/2 teaspoon garlic salt: A simple seasoning that layers more garlicky goodness while seasoning evenly.

How to Make Roasted Sweet Potatoes with Garlic and Parmesan Recipe
Step 1: Preheat Your Oven
Set your oven to 400ºF (200ºC). This high heat will help the sweet potatoes roast to a beautifully caramelized, tender finish without losing their structure. Preheating ensures your potatoes start cooking evenly the moment they go in.
Step 2: Prepare the Sweet Potatoes
Peel and slice your sweet potatoes into thin, even rounds. Thin slices cook faster and create deliciously crispy edges, while staying tender inside. Uniform slices also help with even cooking, so take your time here for the best results.
Step 3: Season and Coat
In a large resealable bag, combine the sweet potato slices with minced garlic, olive oil, melted butter, garlic salt, black pepper, Parmesan cheese, and Italian seasoning. Shake well to ensure every slice is generously coated in this flavorful mixture. This step is where the magic happens: the garlic and Parmesan meld with rich fats to create that irresistible aroma and taste.
Step 4: Arrange in Baking Dish
Lightly butter your baking dish to prevent sticking and start arranging the coated sweet potatoes in a spiral pattern. This not only looks beautiful but promotes even roasting. Overlapping the slices just slightly helps them cook through while forming tender edges.
Step 5: Add Final Touches and Roast
Sprinkle fresh thyme leaves over the top for a burst of herbal fragrance and, if you like, add a little extra Parmesan. Roast in your preheated oven for 30 to 35 minutes, keeping an eye toward the end of cooking to prevent burning. You’ll know it’s ready when the potatoes are fork-tender and the cheese is golden and slightly crisped.
Step 6: Serve Immediately
Once out of the oven, serve your Roasted Sweet Potatoes with Garlic and Parmesan Recipe right away. Garnish with extra fresh thyme if you want to add a touch more color and brightness, making it as delightful to see as it is to eat.
How to Serve Roasted Sweet Potatoes with Garlic and Parmesan Recipe

Garnishes
Fresh herbs like thyme or parsley make gorgeous, fragrant garnishes that complement the rich flavors. A light sprinkle of additional Parmesan or a drizzle of balsamic glaze can also add a sophisticated flair. Don’t overlook garnishes—they can elevate your dish and make your guests’ taste buds sing.
Side Dishes
This dish is incredibly versatile. Pair it with roasted chicken, grilled salmon, or even a simple salad for a balanced meal. The slightly sweet and savory combination of the sweet potatoes works wonders alongside protein and greens, making your whole dinner feel thoughtfully pulled together.
Creative Ways to Present
Try layering the sweet potato slices in individual ramekins or plating them in a stacked tower for impressive presentation. You can also create a festive holiday platter by arranging these roasted gems around a centerpiece roast. Their vibrant color and rustic look fit perfectly with both casual and fancy settings.
Make Ahead and Storage
Storing Leftovers
After the Roasted Sweet Potatoes with Garlic and Parmesan Recipe has cooled, store leftovers in an airtight container in the refrigerator. They will keep well for 3 to 4 days, allowing you to enjoy that comforting flavor on busy nights with minimal effort.
Freezing
While freezing is possible, it’s best to freeze before adding fresh herbs. Place cooled sweet potatoes in a freezer-safe container or bag, removing as much air as possible. They keep nicely for up to 2 months but may lose a bit of their original crispness upon thawing.
Reheating
For best results, reheat leftover roasted sweet potatoes in an oven or toaster oven at 350ºF until warmed through and crispy again. Avoid microwaving if you want to preserve their texture. A quick reheat in a cast iron skillet also works wonders to revive their roasted edge.
FAQs
Can I use regular potatoes in this Roasted Sweet Potatoes with Garlic and Parmesan Recipe?
Absolutely! While sweet potatoes offer a natural sweetness and vibrant color, regular potatoes can be substituted. Just note they might take a bit longer to cook and yield a different flavor profile—more earthy and less sweet—but still delicious.
Is it possible to make this recipe vegan?
Yes, by replacing the butter with a plant-based alternative and using a vegan-friendly Parmesan substitute or nutritional yeast, you can enjoy a delicious vegan version of this dish without losing the rich, garlicky, and cheesy flavors.
What if I don’t have Italian seasoning? What can I use instead?
No worries! You can easily substitute Italian seasoning with a blend of dried oregano, basil, thyme, and rosemary. These herbs capture the essential flavors and keep your Roasted Sweet Potatoes with Garlic and Parmesan Recipe bursting with aromatic goodness.
Can I prepare this dish ahead of time?
You can prep the sweet potatoes and seasoning mixture up to a day in advance and store it covered in the refrigerator. Then arrange and roast just before mealtime for the freshest taste and perfect texture.
How can I make sure the sweet potatoes don’t stick to the baking dish?
Lightly buttering or greasing the baking dish before layering the potatoes is key. Additionally, making sure each slice is well coated in oil and butter helps create a naturally non-stick surface as it roasts.
