Air Fryer Peppers And Onions

Whenever I go grocery shopping, I always have a tendency to overbuy peppers and onions. I just use them in so many recipes, I sometimes end up with too much. Which, if I’m being honest, really isn’t a problem. It just means I will have to cook them in batches and use them in multiple recipes.

I highly recommend this air fryer model right here. I use my air fryer all the time (even daily)!

How To Cook Peppers And Onions In The Air Fryer

Before you start cooking these veggies, remember to make sure to scrub and wash the skin of the peppers first. After you have prepped the bell peppers, cut them in half, and remove the stems and seeds.

Then, slice the bell peppers into strips. I like to cut them about 1/2 inch thick so that they cook evenly through and still have a bite to them.

After you have cut up the bell peppers, peel and slice the onions diagonally to make them the same shape and size as the bell peppers.

Add the pepper and onion slices to a bowl and drizzle them with olive oil. Sprinkle some of the taco seasonings over the top and toss the veggies with your hands until the peppers and onions are evenly coated with the olive oil and seasonings.

Pour all of the veggies into the air fryer basket.

Cooking Tips

  • If you are looking to make this recipe extra yummy, I highly recommend making my homemade taco seasoning. It’s way better than anything you’ll find in a packet or shaker- not to toot my own horn!
  • I like to swap out the taco seasoning for some Italian seasonings or some of my homemade cajun seasoning spice mix!
  • You can also easily add in green bell peppers or add red onions for a tangier flavor profile.
