Smashed potatoes are the perfect balance of crispy exteriors and fluffy interiors, making them a versatile side dish for nearly any meal. Unlike traditional roasted potatoes, which rely heavily on oil and long baking times, smashed potatoes achieve maximum crunch with minimal effort when prepared in an air fryer. The air fryer’s high-velocity hot air circulation ensures a golden, crispy crust without the greasiness of deep frying. Beyond convenience, air-fried smashed potatoes offer a unique opportunity to experiment with seasoning, herbs, and textures, allowing even novice cooks to create restaurant-quality results in their own kitchens. This guide delves into every detail, from temperature control to troubleshooting, ensuring your smashed potatoes come out perfect every time.
Temperature control is the cornerstone of achieving perfectly crispy smashed potatoes. The ideal range for air frying smashed potatoes is 400°F (204°C). At this temperature, the potatoes develop a crunchy, golden-brown exterior while the interior remains tender and fluffy. Temperatures lower than 375°F often result in potatoes that are fully cooked but lack the signature crispiness. Conversely, temperatures above 425°F risk burning the edges before the potatoes are cooked through.
It’s important to preheat your air fryer if your model requires it, as an immediate blast of heat ensures that the oil or fat on the potato surface begins crisping instantly. This high, even heat is what creates the characteristic "smashed" texture that differentiates this dish from standard roasted potatoes.

Cooking time is closely linked to the size of your potatoes. For baby or small Yukon Gold potatoes, 20-25 minutes at 400°F is usually sufficient. Medium-sized potatoes may require 25-30 minutes, while larger potatoes may need 35 minutes.
Timing is best approached in stages: first, boil or steam the potatoes until tender; next, air fry after smashing them. The air fryer acts primarily to crisp the outside. Overcooking during the air frying phase can dry out the interior, so keeping a close eye on both texture and color is crucial.
Determining doneness in smashed potatoes involves both visual and tactile cues:
Combining these observations ensures your potatoes are crispy outside yet perfectly soft inside, avoiding both undercooked or overly dry results.
The beauty of smashed potatoes lies in their simplicity. For 4 servings, you will need:
These ingredients can be customized to suit your taste, making smashed potatoes highly adaptable.
Using a lower temperature (350-375°F) will result in longer cooking times and a less crisp exterior. While the interior may remain tender, the potatoes will not achieve the signature crunch that makes them irresistible.
Higher temperatures (425-450°F) accelerate browning, which can create visually appealing edges but risk burning the surface while leaving the center undercooked. If you choose to experiment with higher temperatures, reduce cooking time and monitor closely, flipping halfway through.
Shorter cooking times may produce tender potatoes but with soft, underdeveloped exteriors. Extending cooking time can enhance crispiness but may dry out the interior or even char the potatoes if left too long. Always aim to balance internal tenderness with external crispness, checking periodically in the last 5 minutes of cooking.
Even experienced cooks encounter mishaps:
Small to medium-sized potatoes with a waxy or all-purpose variety, such as Yukon Gold or red potatoes, are ideal. They hold their shape well during boiling and crisp nicely in the air fryer.
Yes, parboiling the potatoes first is recommended. Boil them until they are fork-tender but not falling apart. This ensures the inside is soft while the air fryer crisps the outside evenly.
After boiling, drain and let the potatoes cool slightly. Place each potato on a cutting board and gently press down with a potato masher, spatula, or the bottom of a cup until they are flattened to about ½ inch thick, ensuring they remain in one piece.
Preheat the air fryer to 400°F (200°C). Cook the smashed potatoes for 15-20 minutes, flipping halfway through, until they are golden brown and crispy on the edges.
Lightly coat the smashed potatoes with olive oil, avocado oil, or another high-heat oil. Season with salt, pepper, garlic powder, or herbs like rosemary and thyme to enhance flavor.
Yes, you can prepare and store boiled potatoes in the refrigerator. When ready to serve, smash, season, and air fry them. Reheating in the air fryer will restore crispiness better than a microwave.
For maximum crispiness, ensure the potatoes are dry before applying oil. Avoid overcrowding the air fryer basket to allow proper airflow. You can also sprinkle a small amount of cornstarch or grated Parmesan cheese for an extra crunchy crust.
