How to Make Garlic Butter Parmesan Smashed Sweet Potatoes

Step 1: Boil the Sweet Potatoes

Wash the sweet potatoes thoroughly and place them in a large pot. Cover with water and boil for about 18–20 minutes, or until fork tender but not falling apart. Drain and allow them to cool slightly.

Step 2: Preheat the Oven

Preheat your oven to 425°F (220°C). Line a baking tray with parchment paper and lightly grease it with olive oil.

Step 3: Smash the Potatoes

Place each cooked sweet potato on the prepared baking tray. Using the bottom of a glass or potato masher, gently press each potato until about ½ inch thick.

Step 4: Prepare the Garlic Butter

Combine melted butter, minced garlic, Italian seasoning, and smoked paprika in a small bowl. Mix until well blended.

Step 5: Season the Potatoes

Brush each smashed potato generously with the garlic butter mixture. Sprinkle with salt, black pepper, and grated Parmesan cheese.

Step 6: Roast Until Crispy

Bake for 25–30 minutes until the edges become crispy and the Parmesan turns golden brown.

Step 7: Garnish and Serve

Top with fresh parsley, thyme, and an extra sprinkle of Parmesan before serving warm.

Expert Tips

Choose Small Sweet Potatoes

Smaller potatoes roast more evenly and create crispier edges.

Don't Over-Boil

Cook until fork tender but firm enough to hold their shape after smashing.

Fresh Parmesan Works Best

Freshly grated Parmesan melts better and creates a delicious crispy crust.

Use Plenty of Garlic Butter

Brushing generously helps achieve rich flavor and beautiful golden color.
