The thing I love about this hack is that it takes ALL of the effort out of cooking spaghetti squash. Y’all know what I’m talking about… When you roast this kind of squash, you have to cut it first. Whether you cut it length-wise or into rings (my preferred style), it’s a tough squash to cut into, and it takes a good amount of elbow grease to get the job done.

That’s why this slow cooker recipe is so glorious. You simply wash the squash and put it into the slow cooker whole with a little water. After it’s done cooking, it softens enough so that you can easily cut it in half and scoop out the seeds before shredding the good stuff. Once it’s prepped, just serve it up with your favorite pasta toppings! We like a red marinara sauce with meatballs or simple butter, parmesan, and salt and pepper.

Expert Tips

  • A good spaghetti squash will be a little heavy for its size and have no soft spots. Check the blemishes out too – some will just be from growing outside but you want to make sure it’s not damaged.
  • When you reheat leftovers, in the microwave or in a skillet with a little olive oil or butter is your best bet. It will help the squash keep its texture.
  • If you have a couple of smaller squashes, you can definitely cook them together. You just want to make sure they’re similar in size so the cooking time will be the same.
  • This method would a fantastic one for meal prep because you can cook get it going while you work on everything else and then it will be ready to shred and store when you’re done.

    what if the squash is too big for the slow cooker? can you cut it in half first?

    1. Melissa says:

      Yes! That’ll work too, just adjust he cooking time as needed, it may cook a little fast since it’s in smaller pieces.
