Your Questions Answered: Air Fryer 101

If you asked ten people what their favorite kitchen appliance is right now, we’re almost sure most would say the air fryer. But what is it exactly? And how does it work? Air Fryers are convection ovens that circulate air to make everything cook really evenly and crispy. Think crispy fries that you think came straight from the fryer at your favorite burger restaurant. Yum!

One of the other reasons we’re a huge fan of the Air Fryer is it preheats immediately! There’s less worrying about the time it takes to get dinner on the table and food tends to cook more quickly and evenly.

How often should you clean your air fryer?


It depends on how much you cook and what you’re cooking! If it’s something like salmon or cheese that has a lot of oil in it, make sure you clean it right after you use it so it doesn’t smell. If it’s something that cooked without leaving much of a mess, we recommend every 2-3 days if you’re consistently using the air fryer.


So what can you make in an air fryer?


Almost anything! We love making breakfast quesadillas that make the tortilla super crispy, mini pizzas, roast chicken, chickpeas, and even donuts! The options are really endless.

Read on for one of our favorite recipes, Air Fryer Donuts. They’re so fun to make as a weekend activity!

Air Fryer Donuts

Prep Time 1 hr 30 mins
Cook Time 5 mins
Servings 6 servings


  • 1 cup plus 2-3 tablespoons whole milk, lukewarm (about 100 degrees)
  • 2 1/2 tsp active dry or instant yeast
  • 1/4 cup plus 1 tsp sugar
  • 1 tsp salt
  • 1 large egg 1/4
  • 1/4 cup unsalted butter
  • 3 cups all-purpose flour
  • 2 cups powdered sugar
  • 1 tsp natural food color, if desired
  • 1/4 cup assorted colored sprinkles


  • Stir together the lukewarm milk, 1 tsp of sugar, and yeast into the bowl of a stand mixer fitted with the dough hook.  Allow the mixture to sit for about 10 minutes or until foamy. If the mixture doesn't bubble, the yeast is too hot or cold and you will need so start over.
  • Add sugar, salt, egg, melted butter and 2 cups of flour to the milk mixture. Turn the mixer on low speed and  add the remaining cup of flour slowly, until the dough is no longer sticky. Increase the mixer speed to medium and knead for about 5 minutes or until the dough is smooth and elastic. 
  • Place the dough into a greased bowl (you can use oil or melted butter) and cover with plastic wrap. Place the bowl in a warm place until doubled (about 1 hour). The dough is ready when you press it with your finger and it leaves an indentation. 
  • Place the dough out onto a floured surface, press it down, and roll out to about 1/2 inch thickness. Using a 3-inch round donut cookie cutter, stamp out donuts. Alternatively you can use a large glass and a shot glass to cut out 1 inch holes from the middle of the donut. 
  • Transfer donuts and holes to parchment paper and cover loosely with greased plastic wrap. Let donuts rise until doubled in volume, about 20-30 minutes. Spray donuts with cooking oil spray. 
  • Turn air fryer to 350 degrees. Transfer donuts to air fryer basket making sure that donuts are 1 inch apart. Spray donuts with oil spray and cook at 350 degrees until golden, about 4-5 minutes. Repeat with remaining donuts and holes.
  • While the donuts are in the Air Fryer, stir milk 1 tablespoon at a time into powdered sugar until smooth. Add food coloring as desired for desired color. Set aside.
  • Dip hot donuts and donut holes in the glaze using to forks to submerge them. Place on a wire rack set over a rimmed baking sheet to allow excess glaze to drip off. Let sit until glaze hardens, about 10 minutes.
