Cheesy Baked Spaghetti Squash with Pesto

I know what you’re thinking… What’s so special about spaghetti squash? I may be the first to say it, but it’s completely underrated. It’s cauliflower’s less popular cousin but oh so good and easy to cook. 

I think people are afraid to eat it because they think it might be gross or don’t know how to cook it. I love spaghetti squash in a way that’s almost judge-worthy. Yes, it’s a bit higher in carbs but worth it. It’s incredibly versatile too.

To pick the best one, you need to know how to tell if spaghetti squash is ripe. 

The more yellow the squash, the riper it is! Uncooked squash doesn’t need to be refrigerated until after you cut/cook them. If you’re taking a chance with Instacart, your best bet is to ask for a very yellow squash.

How to cook spaghetti squash

This squash looks intimidating, but it’s super easy. You can cook spaghetti squash in an air fryer, put it in the Instant Pot, or bake it in the oven. 

For the air fryer and oven, poke the squash with a knife several times before placing it in the microwave on high for about 5 minutes. If it’s a big squash you may need to nuke it for another couple of minutes until it’s easy to cut.

Once you remove it from the microwave (be careful, it will be hot!) place it on a cookie sheet lined with parchment paper or a silicone baking mat. There are a million ways to make it, but the standard is slice, scoop, bake.

Slice the squash lengthwise. I haven’t tried it, but if you want to get wild, cut it horizontally (Like a madman)

Once you cut it, scoop out the seeds and pulp like you would with a pumpkin, drizzle with a keto friendly oil like olive or avocado, and season with a bit of salt. Place the sliced squash face down if going in the oven, or face-up if placing in the air fryer and roast that squash.

When it’s done, scrape it with a fork to get that noodle appearance. This squash is the best noodle replacement in my opinion if you’re trying to keep it clean.

I love to eat it plain, or covered in sauce and cheese. I needed to find some fresh spaghetti squash recipes because the hubs has been judging my squash habit. After enjoying it many times as a noodle sub, I thought about how I could make it a glorious side dish and BOOM….
