Spaghetti squash gets its name from the fact that the inside of the squash transforms into stringy squash strands once its cooked, very much like spaghetti noodles. It is a magical vegetable that you must try!

A lot of people like to serve cooked spaghetti squash as a gluten-free, grain-free, and low-carb alternative to cooked pasta. It’s that time of year when we start to think about low calorie recipes to help off-set the heavier fall and winter dishes.

This Slow Cooker Spaghetti Squash recipe is my new favorite dish.

Key Ingredients

Choose a spaghetti squash that is a nice yellow color with no blemishes. You may need to check the length of the squash to make sure it will fit into your crockpot. You can find spaghetti squash at the grocery store during the fall and winter months.

You’ll also need a cup of water to help provide steam and moisture to keep your spaghetti squash from drying out as it cooks. Just add the water to the bowl of your slow cooker.

Recipe Steps

Step One

The first step is to wash your squash, pat it dry, and then prick it all over with a fork. You want to prick the outside skin of the squash to prevent it from exploding in the bottom of the slow cooker.

Step Two

Next, place your whole squash inside of a large crockpot with a cup of water. Put on the lid and set the cooking time to five hours on high.

Step Three

Your squash will be done when it is fork-tender and you can literally just cut it in half very easily with a sharp knife on a cutting board.

Use a spoon to remove and discard the seeds. Then, use a fork to simply scoop out the “spaghetti” shreds. If you’ve never cooked this type of squash before, you’ll be amazed how the flesh comes apart into noodle-like strands. They have a similar look and texture to pasta noodles.

Serve the squash hot with your choice of toppings. I hope you agree that this is one of the best easy recipes out there! Even if you’re not on a special diet like low carb or gluten-free, this is a great way to cook squash.

Recipe FAQs

How do you serve spaghetti squash?

There are so many things you can do with cooked spaghetti squash! My favorite thing to do is top it with spaghetti sauce. You can add grass-fed ground beef to add protein (use crumbled tempeh for a plant-based version). Top it with parmesan cheese or dairy-free parmesan.
