Par-cook the potatoes. Add mini potatoes to a pot, cover with cold water by 1 inch, and add 1 teaspoon salt. Bring to a boil, then simmer 10–12 minutes until fork-tender but not falling apart.
Drain well and let them steam-dry 2–3 minutes. (Alternatively, microwave in a covered dish with a splash of water for 6–8 minutes until tender.)
Preheat your air fryer to 400°F (200°C). A hot basket helps the crust form fast.
Smash gently. Place the cooked potatoes on a cutting board. Use the bottom of a glass, a measuring cup, or a fork to press down until each potato is about 1/2 inch thick. Aim for cracked edges, not mashed flat.
Season and oil. In a large bowl, whisk olive oil with salt, pepper, garlic powder, onion powder, and smoked paprika.
Add the smashed potatoes and toss carefully to coat. Make sure the oil reaches all those craggy edges for maximum crisp.
Arrange in the basket. Lay the potatoes in a single layer in the air fryer. Don’t stack. Work in batches if needed for even crisping.
Air fry until golden. Cook 10–14 minutes, flipping halfway.
They’re done when the edges are deep golden and the centers feel tender. If you like extra crunch, add 2–3 more minutes.
Finish with flair. Toss with chopped herbs and, if you like, a sprinkle of Parmesan, a squeeze of lemon, or a pinch of red pepper flakes. Taste and adjust salt.
Serve hot. These are best right away, while the edges are shatter-crisp and the middles are soft.
