20-Minute Air Fryer White Fish Fillets with Spinach and Tomatoes

December 31, 2019

These white fish fillets cook up quickly in the air fryer (much faster than the
oven!). Serve with sautéed spinach and tomatoes for a delicious dinner.

New Year, same me!  I’ve never been one to crash diet, or diet in general!  I try to do everything in moderation and still allow myself carbs when I want them (and let’s be honest, the same went for sweets!)  When I purchased an air fryer, I was so excited because I knew I could make some easy cuts to calories in my normal foods that would otherwise be fried in a bunch of oil and fats. Fish is no exception!  This Air Fried Whitefish with Spinach and Tomatoes is a delicious dish that you can feel great eating! And you can’t beat a dinner that takes just 20 minutes!

When I worked in the restaurant industry after culinary school, we made a dish very similar to this one, but the fish was sauteed in lots of olive oil. I love that the air fryer makes cooking fish so much healthier!

What kind of fish is Whitefish?

Whitefish can be classified as either “round” or “flat”, depending on the shape of the fish.

Any of these mild white fish varieties would be a great choice for this dish!  Examples of white, round fish include:

  • Cod
  • Haddock
  • Chilean Sea bass
  • Sole, John Dory
  • Halibut
  • Flounder

What is an air fryer?

If you’re not familiar with what an Air Fryer is, this new kitchen appliance uses circulating hot air to cook food similar to a small convection oven.  Compared to using a deep-fryer, the air fryer reduces the amount of fat and calories in your food. It has cut my cooking time in half and made foods that would normally be loaded in calories so much healthier! 

When you use parchment paper to cook whitefish in the air fryer, there’s no sticking and super easy cleanup. It makes cooking delicate fish so much easier to release without sticking or tearing the fish. You can find air fryer parchment sheets that are perforated, which allows air to circulate through and provide more even cooking. They are super easy to use. There are many different sizes, so make sure you buy the one that fits your air fryer basket! 

If you don’t have the parchment sheets specific to an air fryer, just regular parchment is fine! The air fried whitefish will come out perfect every time, and in under 15 minutes!

What’s not to love about cooking fish in an air fryer? With air fryer fish recipes, you cut your cooking time in half, and clean up is a breeze with parchment paper! The air-fried whitefish comes out fantastic and always perfect within minutes.   I simply seasoned the filets with salt, pepper, and paprika for an easy meal.  I’m skipping out on the breadcrumbs because I want to keep this dish as simple and healthy as possible!

Air Fried Whitefish with Spinach and Tomatoes

  • Author: Nicole Triebe
  • Prep Time: 5 minutes
  • Cook Time: 12 minutes
  • Total Time: 20 minutes
  • Yield: 2 1x
  • Category: Dinner
  • Method: Air Fryer
  • Cuisine: Italian



2 x 6 oz whitefish filets


Salt and pepper

For the sauce:

3 tbl butter

2 tbl balsamic vinegar

Pinch of salt

8 oz spinach

mushrooms (oyster)

grape tomatoes




Preheat the Air Fryer to 360°F for 5 minutes.
Rinse and pat dry the whitefish filets. Spray with coconut oil spray and season with salt, pepper, and paprika on both sides.
Place parchment paper or air fryer baking paper inside the base of the air fryer basket. Lightly spray the paper with coconut oil
Place the fish on top of the paper
Air Fry at 360°F for about 6-12 minutes, depending on thickness.  You should be able to easily flake the whitefish with a fork. Thicker filets will take longer to cook.

Make the brown butter by melting butter over medium heat. Use a pan with a light-colored bottom so you can keep track of the color. Swirl the pan occasionally to be sure the butter is cooking evenly.

As the butter melts, it will begin to foam. The color will change from lemony-yellow to golden-tan to, finally, a toasty-brown. Once you smell a nutty aroma, take the pan off the heat and transfer the browned butter into a heat-proof bowl to cool.  Add balsamic vinegar and stir to combine.

In a medium saute pan over medium heat, add 1 tbl butter and melt.  Add mushrooms and tomatoes until tomatoes begin to burst and mushrooms soften.  Add spinach and cover with a lid until it wilts.  Add half the brown butter balsamic sauce to the spinach and mushrooms.

When plating, place spinach on the bottom and fish over top.  Top with additional brown butter balsamic sauce.  Serve!
