Step 1 Prepare the Potatoes
Wash the potatoes thoroughly under cold running water. Leave the skin on for extra texture and flavor or peel them if preferred. Slice the potatoes into even half inch rounds to ensure they cook evenly. Place the slices into a bowl of cold water for fifteen minutes to remove excess starch. Drain well and pat completely dry with paper towels.
Step 2 Prepare the Onion
Peel the onion and cut it into thick slices or wedges. Separate the layers gently so they cook evenly and caramelize beautifully in the air fryer.
Step 3 Make the Seasoning
In a large bowl combine olive oil, avocado oil, minced garlic, onion soup mix, rosemary, paprika, garlic powder, black pepper, and salt. Stir until everything is fully blended into a flavorful coating.
Step 4 Coat the Vegetables
Add the dried potato slices and onions into the bowl. Toss everything thoroughly until every piece is coated with the seasoned oil mixture. Make sure the garlic and herbs are evenly distributed for maximum flavor.
Step 5 Preheat the Air Fryer
Preheat your air fryer to 390 degrees Fahrenheit for about three to five minutes. Preheating helps create crispier potatoes and ensures even cooking from the start.
Step 6 Arrange in the Basket
Place the potatoes and onions into the air fryer basket in a single layer. Do not overcrowd the basket because proper air circulation creates crispy edges. Cook in batches if necessary.
Step 7 Air Fry Until Crispy
Cook for twelve minutes. Shake the basket or flip the potatoes carefully. Continue cooking for another ten to thirteen minutes until the potatoes are golden brown with crispy edges and the onions are caramelized and tender.
Cooking times may vary slightly depending on your air fryer model and the thickness of your potato slices.
Step 8 Garnish and Serve
Transfer the hot potatoes and onions to a serving bowl. Sprinkle with fresh chopped parsley and serve immediately while hot and crispy.

Storage Instructions
Allow leftovers to cool completely before storing. Place them in an airtight container and refrigerate for up to four days.
Reheating
Reheat in the air fryer at 375 degrees Fahrenheit for four to six minutes until hot and crispy again. Avoid using the microwave if possible because it softens the potatoes.
Freezing
Freeze cooled potatoes in a freezer safe container for up to two months. Reheat directly from frozen in the air fryer until heated through and crispy.
Frequently Asked Questions
Can I use red potatoes
Yes. Red potatoes hold their shape well and develop a delicious crispy skin.
Do I have to soak the potatoes
Soaking is recommended because it removes excess starch and helps produce crispier potatoes.
Can I make this recipe without onion soup mix
Yes. Replace it with additional garlic powder, onion powder, paprika, salt, black pepper, and dried herbs.
Can I prepare everything ahead of time
Yes. Slice and season the potatoes several hours ahead. Refrigerate until ready to air fry.

Overcrowding the basket or leaving moisture on the potatoes can prevent crispiness. Always dry the potatoes thoroughly and cook in batches if needed.
