Air Fryer Peppers and Onions

Bell peppers are always extra good in the fall, and Air Fryer Peppers and Onions are really a wow for an extra-easy side dish! Check the oven directions if you don’t have an Air Fryer.

This new recipe for Air Fryer Peppers and Onions is so easy and good that it might end up being one of your favorite side dishes! I know some people aren’t bell pepper fans, but I love grilled peppers, roasted peppers, and stuffed peppers, so I had no doubt that I’d love peppers and onions cooked in the Air Fryer. And when I tested this recipe with Kara, we both thought it was completely a wow!

And if you don’t take time to marinate (which is completely optional) you can make the entire recipe including cutting up the veggies in about 20 minutes, which is also pretty great! This is another one of those recipes where I thought the Newman’s Own Classic Oil and Vinegar Dressing that I featured recently gave it just an extra touch of flavor! Check instructions for roasting this in the oven if you don’t have an Air Fryer, and give this a try if you’re also a fan of peppers. 

What ingredients do you need for this recipe?

What Air Fryer Did I use?

I became a big Air Fryer fan after I discovered the Cuisinart Convection Air Fryer Toaster Oven (affiliate link) which is what I used for this recipe. This air fryer has a larger basket, which was big enough to do three large peppers and a large onion but if your Air Fryer has a smaller basket you might need to cut the recipe in half.

What if you don’t have an Air Fryer?

You can definitely cook this side dish of sausage and peppers in the oven if you don’t have an air fryer. I would cook them at 450F/230C. Follow directions for preparing the vegetables and tossing with the seasonings, then drain them spread the vegetables out on a large baking sheet. The Air Fryer cooks hotter like a convection oven, so they will take a bit longer in the oven even if the temperature is higher. I’d start to check the oven-roasted peppers and onions after 10 minutes, and they’ll probably take about 15 minutes, depending on how crisp you like them.

  3. Put onions and peppers into a Ziploc bag or a bowl and toss with Newman's Own Classic Oil and Vinegar Dressing and Italian Herb Seasoning.

  6. Set Air Fryer to 400F/205 C. Preheat if your Air Fryer needs it.

  8. Then cook 3-4 minutes longer, or until done to your liking.
  9. We liked the peppers and onions when they were still slightly crisp, so adjust the cooking time depending on how soft you like them.
  10. Season to taste with salt and fresh-ground black pepper and serve hot.
  11. TO COOK PEPPERS AND ONIONS IN THE OVEN: Preheat oven to 450F/230C. Follow directions for preparing vegetables and tossing with seasonings, then spread vegetables out on a large baking sheet. I'd start to check the oven-roasted peppers and onions after 10 minutes, and they'll probably take about 15 minutes, depending on how crisp you like them.

  1. I have that exact same air fryer but I thought my direction said never to use aluminum foil with it. Any reason not to?

    • I haven’t heard that. I’ve been wrapping my lower tray in foil for months now and no problems. I wonder if they mean don’t try to use the air fryer to cook foods in foil?

  2. Is it 450º in the air fryer?

    I love peppers and onions and am delighted for this option! Thanks!

  3. Looks good and yummy. Does using air fryer deplete the nutrients of vegetables?
