How To Air Fry Italian Sausage With Peppers and Onions

Step 1: Slice and cook onions

Add sliced onions to your air fryer-safe pan (usually if it’s oven safe, it is air fryer safe). Mix with 1 tablespoon of olive oil until the onions are well coated.

Air fry the onions for 7 minutes at 390 degrees F (air fryer setting). I mixed mine after 3 minutes, and they came out tender but crisp on the edges.

Step 2: Slice and cook the bell peppers

Swap the pan of onions in the basket for a pan of bell peppers. You’ll want to coat those with about 1 tablespoon of olive oil as well.

Cook for the same amount of time — 7 minutes at 390 degrees F, flipping about halfway. Mine had a nice texture, still firm but not soggy.

You can also cook the onions and peppers at the same time. If so, use less oil.

Step 3: Air fry Italian sausage

Remove the peppers and place the Italian sausage in the air fryer basket.

Cook for 20 minutes at 390 degrees F or until cooked all the way through. I suggest flipping these halfway as well so they brown on all sides.

Step 4: Combine and serve

Slice up the links if desired, then serve air fryer Italian sausage and peppers with onions and your favorite side or pile it all on a hoagie roll. Enjoy!

How To Save Leftovers

If you are cooking for yourself or make enough to have leftovers for lunch the next day, you can easily store them for about 2-3 days in the refrigerator. Keep in an airtight container for optimum freshness.

To freeze: If you want to freeze the extra portion, store in a freezer-safe container. It will keep in the freezer for 2 to 3 months. Thaw in the refrigerator and reheat in either the air fryer or microwave.

Serving Suggestions

This dish is traditionally served with a huge side of French Fries, but you can certainly pair it with whatever you would like! Spoon ____ over some rice or try one of these other popular sides:

You can also layer sausage peppers and onions into a sandwich roll with tomato sauce or your favorite dip.

What Type Of Sausage Can I Use With This Recipe?

I tend to stick to my roots and use Italian sausage in this air fryer recipe — they come in both hot and sweet. Since I have kids, I usually pick up sweet sausages, but obviously, hot would work the same way.

Other great options are smoked sausage, sweet sausage, andouille sausage, and even chorizo sausage.

Which Color Bell Pepper Is The Best?

I tend to use various colored bell peppers in my recipes; the reason is simple, they look better.  They sell a package of three peppers in my grocery store — usually red, green, and either yellow or orange. Any combination works for this sausage peppers and onions recipe.

How Long Do You Cook Italian Sausage In Air Fryer?

Set the air fryer to 400 degrees F, air fryer setting, and cook until the sausages are completely cooked. The exact time will depend on your air fryer, but the average time is 8-12 minutes.

Use a meat thermometer to make sure they are fully cooked, as the internal temperature should reach 160 degrees F.

Can I Make This Sausage Peppers And Onions Recipe Spicier?

If you really want to add some heat to this dish, I would suggest that you change out your sausages. You can either use Italian Hot Sausages or even Chorizo Sausages. You can also do a blend of the mild and hot Italian sausages to please everyone! 

Another great option would be to add some chili pepper flakes or a few dashes of hot sauce right before serving.
