Prep Time: 5 minutes Cook Time: 15 minutes Total Time: 20 minutes Serves: 4-6 people
Key Ingredients for Air Fryer Potatoes and Onions:
- 2 pounds baby potatoes (or Yukon Gold), cut into 1-inch pieces
- 1 large yellow onion, sliced into half-moons
- 3 tablespoons olive oil
- 1 teaspoon garlic powder
- 1 teaspoon dried rosemary (or 2 teaspoons fresh)
- 1 teaspoon paprika
- 1/2 teaspoon dried thyme
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 2 tablespoons fresh parsley, chopped (for garnish)
- Optional: 1/4 cup grated Parmesan cheese

Step-by-Step Instructions:
Step 1: Prepare the Vegetables Wash and cut the potatoes into uniform 1-inch pieces. Leave the skin on for extra nutrition and texture. Slice the onion into half-moon shapes about 1/4-inch thick. Pat the potatoes dry with paper towels to remove excess moisture.
Step 2: Season the Mixture In a large bowl, combine the cut potatoes and sliced onions. Drizzle with olive oil and toss until everything is well coated. Add garlic powder, rosemary, paprika, thyme, salt, and pepper. Mix thoroughly to ensure even seasoning distribution.
Step 3: Preheat the Air Fryer Preheat your air fryer to 400°F (200°C) for 3-5 minutes. This ensures even cooking from the start and helps achieve that perfect crispy exterior.
Step 4: First Cook Cycle Place the seasoned potatoes and onions in the air fryer basket in a single layer. Don’t overcrowd – cook in batches if necessary. Cook for 10 minutes, shaking the basket halfway through to ensure even browning.
Step 5: Check and Continue Cooking After 10 minutes, check for doneness. The potatoes should be golden brown and tender when pierced with a fork. If needed, cook for an additional 3-5 minutes, shaking the basket once more.
Step 6: Final Touches Remove from the air fryer and immediately sprinkle with fresh parsley and optional Parmesan cheese. Serve hot for the best texture and flavor.
What to Serve Air Fryer Potatoes and Onions With:
This versatile side dish pairs beautifully with grilled chicken, roasted beef, or chops. For a complete meal, serve alongside a fresh green salad and steamed vegetables. The crispy potatoes also complement fish dishes like salmon or cod perfectly.
Consider serving with a dollop of sour cream or a drizzle of ranch dressing for extra indulgence. For a Mediterranean twist, pair with grilled lamb and a cucumber yogurt sauce. The dish also works wonderfully as part of a breakfast spread alongside scrambled eggs and bacon.

Top Tips for Perfecting Air Fryer Potatoes and Onions:
Choose the Right Potatoes Baby potatoes or Yukon Gold varieties work best because they hold their shape and develop a creamy interior. Avoid russet potatoes as they tend to become too fluffy and may fall apart during cooking.
Don’t Skip the Drying Step Pat your potatoes completely dry before seasoning. Excess moisture prevents proper crisping and can make your potatoes soggy. This simple step makes a huge difference in the final texture.
Avoid Overcrowding Cook in batches if necessary to ensure proper air circulation. Overcrowded baskets result in unevenly cooked potatoes with some pieces remaining soft while others become overcooked.
Shake for Even Cooking Shake the basket 2-3 times during cooking to ensure all sides get evenly browned. This prevents sticking and promotes uniform crispiness throughout.
Adjust Cooking Time by Size Smaller potato pieces cook faster, while larger chunks need more time. Keep pieces uniform in size for consistent results. If your potatoes are particularly large, increase cooking time by 2-3 minutes.
Storing and Reheating Tips:
Storage Instructions Store leftover air fryer potatoes and onions in an airtight container in the refrigerator for up to 4 days. Allow them to cool completely before storing to prevent condensation that can make them soggy.
Reheating for Best Results Reheat in the air fryer at 350°F for 3-5 minutes to restore crispiness. Alternatively, reheat in a conventional oven at 400°F for 5-7 minutes. Avoid microwaving as this will make the potatoes soft and eliminate the crispy texture.
Freezing Options While best enjoyed fresh, you can freeze cooked potatoes for up to 2 months. Freeze in a single layer on a baking sheet first, then transfer to freezer bags. Reheat directly from frozen in the air fryer, adding 2-3 extra minutes to the cooking time.

Frequently Asked Questions
Can I use different types of potatoes?
Yes! While baby potatoes and Yukon Gold work best, you can use red potatoes or even sweet potatoes. Adjust cooking time accordingly – sweet potatoes may cook faster.
Do I need to peel the potatoes?
No, leaving the skin on adds nutrition, texture, and saves time. Just make sure to wash them thoroughly before cutting.
Can I make this recipe oil-free?
You can reduce the oil to 1 tablespoon or use cooking spray, but the potatoes won’t be as crispy. The oil helps achieve that golden, crispy exterior.
What if I don’t have an air fryer?
You can make this recipe in a conventional oven at 425°F for 25-30 minutes, flipping halfway through. The air fryer just makes it faster and crispier.
Can I prep this recipe ahead of time?
You can cut the vegetables and store them in the refrigerator for up to 24 hours. However, for best results, season and cook them fresh.
Why are my potatoes not crispy?
Common causes include overcrowding the basket, not patting potatoes dry, or using too little oil. Make sure to follow the drying and spacing tips for best results.
Can I add other vegetables?
Absolutely! Bell peppers, mushrooms, or zucchini work well. Just keep in mind that different vegetables have different cooking times.
How do I know when the potatoes are done?
They should be golden brown on the outside and tender when pierced with a fork. The internal temperature should reach 210°F for perfectly cooked potatoes.
Creative Variations to Try
Mediterranean Style: Add dried oregano, lemon zest, and crumbled feta cheese after cooking.
