❤️ Why I Love This Recipe

Sweet potatoes often lean sweet in most recipes—but this version goes bold with savory flavor. Garlic, Italian seasoning, cracked black pepper, and Parmesan create that irresistible balance of umami and richness.

Best of all, it’s ridiculously easy. Everything gets tossed together in a bag (minimal mess!) and arranged into a beautiful spiral before roasting to perfection. It’s a dish that looks impressive but takes very little effort.


🛒 Ingredients

  • 2 medium sweet potatoes, peeled and thinly sliced
  • 2 tsp minced garlic
  • 1 tbsp olive oil
  • 2 tbsp butter, melted
  • 4 tbsp grated Parmesan cheese
  • 1/2 tsp garlic salt
  • 1/2 tsp freshly cracked pepper
  • 1/2 tsp Italian seasoning
  • Fresh thyme (for garnish)

🔁 Ingredient Notes & Swaps

  • Butter + Olive Oil: The combo gives flavor and crispness. Use all olive oil for dairy-free or all butter for richness.
  • Parmesan: Fresh grated Parm works best, but pre-grated is fine too.
  • Garlic Salt: Can substitute with regular salt + garlic powder.
  • Italian Seasoning: Swap in rosemary, thyme, or oregano if you want to customize.
  • Sweet Potatoes: Use uniform slices so they cook evenly—about 1/8 to 1/4 inch thick.

👨‍🍳 How to Make Garlic Parmesan Roasted Sweet Potatoes

Step 1: Preheat and Prep

Preheat your oven to 400°F (200°C). Lightly butter or oil a round baking dish.

Step 2: Season the Sweet Potatoes

Place your sliced sweet potatoes into a large resealable bag or bowl. Add:

  • Garlic
  • Olive oil
  • Melted butter
  • Garlic salt
  • Pepper
  • Parmesan
  • Italian seasoning

Seal the bag and shake until fully coated.

Step 3: Assemble in the Dish

Arrange the slices in a spiral or overlapping pattern in your prepared baking dish. Sprinkle with fresh thyme and a little extra cheese if desired.

Step 4: Roast

Bake for 30–35 minutes or until the potatoes are tender and the edges are golden and crisp.

Step 5: Serve

Let cool for 5 minutes. Garnish with more thyme and serve warm. Trust us—they disappear fast!


💡 Tips for Success

  • Use a mandoline slicer for perfectly even rounds that roast evenly.
  • Fan out slices slightly for visual appeal and better texture.
  • Want extra crisp edges? Broil for the last 1–2 minutes of baking.
  • Don’t crowd the dish too tightly—airflow helps crisp things up.
