The Secret to Perfect Roasted Sweet Potatoes

There are a few simple techniques that make this recipe absolutely foolproof:

Cut the sweet potatoes evenly

Uneven pieces will cook at different speeds. Aim for 1-inch cubes.

Don’t overcrowd the pan

Crowding traps steam and prevents crisping. Use two pans if needed.

Roast at high heat

425°F is the sweet spot for caramelization.

Add Parmesan at the right time

Roasting with the potatoes helps it melt into a crisp crust.

Flip halfway through

This ensures even browning and crispy edges on all sides.

Ingredients You’ll Need

  • Sweet Potatoes: Peeled and cubed.
  • Olive Oil: Helps crisp and brown the potatoes.
  • Garlic: The star seasoning — use fresh for best flavor.
  • Parmesan: Adds salty richness and crispiness.
  • Salt and Pepper: Essential for balance.
  • Italian Seasoning: Adds herbaceous depth.
  • Parsley: Optional garnish for color and freshness.

Simple ingredients, big flavor.

  • 3 large sweet potatoes, peeled and cubed
  • 3 tbsp olive oil
  • 4 cloves garlic, minced
  • 1/2 cup grated Parmesan
  • 1 tsp Italian seasoning

Instructions

1. Prep the Oven and Pan
