Main Ingredients

  • 2 large sweet potatoes peeled and cut into 1-inch cubes
  • 1 lb green beans trimmed
  • 2 tablespoons olive oil
  • 1 teaspoon dried rosemary crushed
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon onion powder

Instructions
 

Preparation

  • Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
  • In a large bowl, combine the cubed sweet potatoes and trimmed green beans.

Seasoning & Roasting

  • Drizzle olive oil over the vegetables, then sprinkle with dried rosemary, garlic powder, onion powder, salt, black pepper, and optional red pepper flakes. Toss to coat evenly.
  • Spread the seasoned vegetables in a single layer on the prepared baking sheet, ensuring they are not overcrowded.
  • Bake for 20-25 minutes, or until tender and lightly caramelized; stir or flip halfway through for even browning.

Serving

  • Remove from the oven, garnish with fresh parsley or chives if desired, and serve hot.

For extra flavor, you can add a squeeze of lemon juice after roasting.
