❤️ 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

🔁 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.
