Inspiration Behind the Recipe

Over the summer we were making pesto like crazy. It’s such a refreshing sauce to add to grilled veggies, fish, and chicken. We were craving this refreshing taste but wanted to tone it down and make it a tad bit creamier. That is where the cashews come in. Many pesto recipes like our Pesto Salmon Skewers, call for walnuts or pecans, but when they are ground up they produce a tangier taste. Cashews, like almond product a creamier accent to the sauce.

Tools Needed to Create

Blender/Food Processor: To quickly blend up the pesto, use a blender or food processor.

Air Fryer: We tailored this recipe around cooking the salmon in the air fryer. Linked is the one we have and LOVE!

Ingredients You Need to Have

Salmon: There is just something about pesto and salmon that pair so well together. We prefer fresh Atlantic salmon but whatever is your preference go for it!

Spaghetti Squash: Honestly I think this dish would be so amazing with butternut squash noodles but it’s time consuming and this dish is so simple and quick, I didn’t want to spoil it with a time consuming task. Spaghetti Squash is so fresh and tasty, it’s perfect for this.

Cashews: Like I wrote about at the top of this post, this type of nuts make for a creamier pesto sauce.

Basil: Basil paired with cashews are the perfect combo!

Parmesan: What would a pesto be without a creamy parmesan cheese added to the sauce and then again sprinkled on top. Do yourself a favor and grate fresh parmesan for this. It really does make a world of a difference.

Lemon: Any pesto requires a little acid to give you that perfect velvety taste and flavor.

Step by Step Instructions

Preheat your oven to 400 degrees. While the oven is preheating slice the spaghetti squash in half length-wise and scoop out the seeds. Drizzle olive oil, salt, pepper, and nutmeg over the spaghetti squash and bake face down on a rack for 45-50 minutes. While the spaghetti squash is cooking, go ahead and combine all of your pesto ingredients into your blender and blend until smooth. Add additional oil if needed based on your desired thickness.

Turn your air fryer on and let preheat to 400 degrees. Slather both sides of the salmon with pesto. You should have a thick layer of pesto around the salmon. Remove tray, spray with olive oil, and add salmon to rack. Cook for 5 minutes and flip the salmon, let cook another 5 minutes. In a small sauce pan add the remainder of your pesto and whisk to heat up.

Remove the spaghetti squash from the oven and make the “spaghetti” using a fork. Add your salmon over the squash and then additional pesto to your linking. Garnish with extra parmesan and serve your Pesto Salmon Spaghetti Squash!
