Is Spaghetti Squash a Carb? 

First, let’s address the burning question: Is spaghetti squash a carb? The answer is yes, but the carb content is significantly lower compared to traditional pasta, and of course, it has no gluten. 

While regular pasta is primarily made from wheat flour and is relatively high in carbohydrates, spaghetti squash is a vegetable that contains carbohydrates in the form of natural sugars and dietary fiber. 

Named for the way its cooked flesh naturally resembles delicate strands of spaghetti, this yellow squash has a slightly sweet and nutty flavor.

We eat a lot of spaghetti squash when it’s in season. Since we limit our consumption of gluten and wheat, I’m always looking for alternatives. Spaghetti squash definitely has more of a “spaghetti feel” than “zoodles” when you’re trying to watch your carbs or just eat more vegetables.

If you aren’t vegan or following Whole30, this spaghetti squash recipe is fantastic with a generous sprinkle of parmesan cheese. Sometimes I’ll add grilled chicken or serve it with Pesto or No-Cook Summer Pasta Sauce.

How to Make Spaghetti Squash Noodles

Choose the perfect squash: Look for a spaghetti squash that feels heavy for its size and has a firm, matte skin. Avoid any with soft spots or blemishes.

Prepare your squash: Preheat your oven to 350°F. There are a couple different ways to cut spaghetti squash. Slicing it into thick rings will produce shorter, bite-sized strands. Cutting it in half lengthwise produces longer spaghetti-like strands. Using a sharp knife, carefully cut the squash as you prefer. Scoop out the seeds and stringy bits using a spoon.

Roasting: Place the squash rings/halves cut-side down on a baking sheet lined with parchment paper. Roast them in the preheated oven for about 35-45 minutes or until the flesh is tender. You can tell it’s done when a fork easily pierces the skin and flesh.

Creating the Noodles: Once the squash is cooked and slightly cooled, use a fork to gently scrape the flesh. The flesh will naturally separate into strands resembling spaghetti.

Can you microwave spaghetti squash?

If you’re short on time, you can microwave spaghetti squash. 

Pierce the squash with a knife several times to release steam. Microwave the squash whole for a few minutes until it’s soft enough to cut into. 

Slice it either horizontally or vertically. Scoop out the seeds and stringy bits, then continue microwaving, a few minutes at a time, by placing the halves in a shallow microwaveable dish with a little bit of water.

This should take a total of 10 minutes.

Once your squash is cooked and separated into spaghetti strands, top it with your favorite veggies or sauce.
