This simple recipe for how to cook a whole spaghetti squash in the slow cooker is the best set-it-and-forget-it hack — when you can prepare a vegetable this easily, there’s no reason not to cook it more often!
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.
