Ingredients

  • 3 medium-sized potatoes (Yukon Gold or Russet work best), washed and diced into 1-inch cubes
  • 1 large yellow onion, peeled and cut into thin wedges
  • 2 tablespoons olive oil or avocado oil
  • 1 teaspoon garlic powder
  • 1 teaspoon smoked paprika
  • 1 teaspoon dried thyme or rosemary
  • Salt and freshly ground black pepper, to taste
  • Fresh parsley for garnish (optional)

Equipment

  • Air fryer (5-quart capacity recommended for even cooking)
  • Mixing bowl for tossing potatoes and onions with oil and seasonings
  • Sharp knife and cutting board
  • Spatula or tongs for shaking or turning the potatoes midway through cooking
  • Measuring spoons

Instructions

  1. Prepare the potatoes and onions: Wash and dice the potatoes into 1-inch cubes, making sure they are similar in size for even cooking. Peel the onion and cut it into thin wedges.
  2. Season the vegetables: In a large mixing bowl, combine the diced potatoes and onion wedges. Add the olive oil, garlic powder, smoked paprika, dried thyme, salt, and pepper. Toss everything thoroughly until the potatoes and onions are well coated with the oil and spices.
  3. Preheat the air fryer: Preheat your air fryer to 400°F (200°C) for about 5 minutes. This ensures the potatoes start cooking immediately and get crispy.
  4. Cook in batches if necessary: Place the seasoned potatoes and onions in the air fryer basket in a single layer. Avoid overcrowding to allow hot air to circulate properly and achieve crispiness.
  5. Air fry: Cook for 15 minutes at 400°F, then pause to shake the basket or use tongs to turn the potatoes and onions for even cooking. Continue cooking for another 10-15 minutes until the potatoes are golden brown and tender, and the onions are caramelized.
  6. Check doneness: Pierce a potato cube with a fork to ensure it is tender inside. If necessary, cook for an additional 3-5 minutes to get the desired crispiness.
  7. Serve: Transfer the potatoes and onions to a serving dish, garnish with freshly chopped parsley if desired, and serve immediately for the best texture and flavor.

Tips & Variations

For extra crunch, soak diced potatoes in cold water for 30 minutes before cooking, then pat dry thoroughly to remove excess starch.

Feel free to experiment with different herbs and spices. Rosemary, oregano, or even a pinch of cayenne pepper can add a new dimension of flavor.

For a cheesy twist, sprinkle some grated Parmesan or vegan cheese during the last 5 minutes of air frying.

Want to add more veggies? Bell peppers, zucchini, or mushrooms work wonderfully when tossed in with the potatoes and onions.

Just adjust cooking time accordingly.

If you don’t have an air fryer, this recipe can be adapted for oven roasting at 425°F (220°C) for about 30-40 minutes, turning halfway through.
