Use your air fryer to make the most perfectly crispy and brown smashed potatoes! By steaming the potatoes in the microwave first, you can make these smashed potatoes in only about 25 minutes.


Units Scale
  • 1 pound new (aka "baby") potatoes (see note 1)
  • 2 tablespoons olive oil (or other cooking oil)
  • 1/2 teaspoon dried crushed rosemary (see note 2)
  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon onion powder
  • kosher or table salt, to taste


  1. If needed, scrub the potatoes with water. Place the potatoes in a medium microwave-safe bowl. Pierce each potato with a fork. Add about 3 - 4 tablespoons of water to the bowl. 
  2. Cover the bowl with microwave-safe plastic wrap, leaving at least a 1 inch (2.5 cm) gap between the top of the potatoes and the plastic. Also leave a 1 inch (2.5 cm) space uncovered to serve as a vent. (Or, cover the bowl with a vented lid designed for microwave use.)
  3. Microwave the potatoes on high for 5 - 8 minutes, or until the potatoes are fork-tender. Then remove the lid (be careful of trapped steam and hot water clinging to the lid!) and let the potatoes sit for a minute or two, until they are cool enough to handle.
  4. Meanwhile, stir together the oil, dried rosemary, dried thyme, and onion powder.
  5. Right before you are ready to smash the potatoes, pre-heat the air fryer to 400 degrees F.
  6. Place the potatoes onto a clean work surface. Dry each potato with a paper towel. Using either a spatula, potato masher, or glass with flat bottom, smash each potato to about 1/2 inch (1.3 cm) in thickness. 
  7. Gently brush or drizzle the seasoned oil onto the surface of each potato. Sprinkle the potatoes with salt to taste.
  8. Using a spatula, place the smashed potatoes into the pre-heated air fryer, evenly spaced and in a single layer (see note 3). Air fry for 10 - 12 minutes, or until the potatoes are crispy and browned to your liking!


(1) You can use any type of new (aka "baby") potato. For best results, look for baby potatoes that are on the medium to large size (for baby potatoes!) - about 1 1/2  - 2 inches in length. 

(2) If you have whole leaf dried rosemary, crush it in your hands before adding to the oil.

(3) If the smashed potatoes don't all fit in a single layer, you can air fry them in two batches.

(4) Cook times are given in ranges; the exact times needed will vary based on your own appliances (microwave and air fryer), and how large the potatoes are. Adjust the cook times as needed.

(5) You can use the air fryer to pre-cook the potatoes instead of the microwave. Pierce the potatoes with a fork and cook them in a pre-heated 325 degree F air fryer for 18 - 22 minutes, or until fork-tender. Shake the air fryer basket halfway through the cook time.
