There is something truly magical about the way a high-heat oven transforms humble root vegetables. These roasted potatoes are the definition of a reliable side dish—crispy on the edges, fluffy in the center, and bursting with the natural sweetness of caramelized peppers and onions. It's a colorful addition to any plate that feels both rustic and sophisticated at the same time.

What I love most about this recipe is its sheer versatility. Whether you’re serving it alongside grilled steak, roast chicken, or even topping it with a few fried eggs for a hearty weekend breakfast hash, it never fails to satisfy. The secret lies in using a hot oven and not crowding the pan, which ensures every single piece gets that golden-brown finish we all crave.

Directions

  1. 1
    Oven preheated to 425 degrees for roasting vegetables

    Preheat your oven to 425°F (220°C).

  2. 2
    Cubed potatoes, peppers, and onion wedges combined on a sheet pan

    On a large rimmed baking sheet, combine the cubed potatoes, chopped peppers, and onion wedges.

  3. 3
    Olive oil and spices sprinkled over potatoes, peppers, and onions

    Drizzle the olive oil over the vegetables. Sprinkle with garlic powder, oregano, smoked paprika, salt, and black pepper.

  4. 4
    Vegetables tossed with oil and spices on the sheet pan

    Use your hands or a spatula to toss everything together until the vegetables are thoroughly and evenly coated with the oil and spices.

  5. 5
    Seasoned vegetables spread in a single layer before roasting

    Spread the mixture out into a single layer. If the pan is too crowded, use two pans to ensure the potatoes roast instead of steam.

  6. 6
    Roasted potatoes, peppers, and onions tossed halfway through cooking

    Roast for 30 to 35 minutes, tossing the vegetables halfway through, until the potatoes are tender and golden brown.

  7. 7
    Finished roasted potatoes with peppers, onions, and fresh parsley

    Remove from the oven, garnish with fresh parsley, and serve immediately while hot.

Ingredients

  • Yukon Gold potatoes, cut into 1-inch cubes:2 lb
  • Red bell pepper, chopped:1 piece
  • Green bell pepper, chopped:1 piece
  • Large yellow onion, sliced into wedges:1 piece
  • Extra virgin olive oil:3 tbsp
  • Garlic powder:1 tsp
  • Dried oregano:1 tsp
  • Smoked paprika:1 tsp
  • Kosher salt:1 tsp
  • Black pepper:½ tsp
  • Fresh parsley, chopped:2 tbsp

Tips & Notes

  • Try to cut the potatoes into uniform sizes so they all finish cooking at the same time.
  • For extra crispiness, leave the baking sheet in the oven while it preheats so the vegetables hit a hot surface.
  • Yukon Gold potatoes are ideal here because they hold their shape well and have a naturally buttery texture.
