Wash the spaghetti squash thoroughly under running water to remove any dirt from the skin.
Using a fork or a paring knife, make small holes in the spaghetti squash skin.
Place it in the microwave. Cook it on high for 4 minutes.
Carefully remove the squash from the oven and let it rest for a minute or two. With a chef’s knife, slice it lengthwise from top to bottom, right down the middle. Use a spoon to scoop out the seeds and any loose fibers.
Cook spaghetti squash in slow cooker
Season with salt and pepper.
Place the squash halves in a slow cooker, cut side up.
Add 1 cup of water.
Cover and cook on low for 4-6 hours or until the squash is tender.
Let it cool slightly and scrape the squash into strands.
Notes
The cup of water in the bottom of the slow cooker is essential for creating steam that cooks the squash evenly without drying it out.
Pre-cooking the squash in the microwave for 4 minutes makes it easier to cut through and reduces overall cooking time. (please link to "microwave spaghetti squash")
Season the inside of the squash generously with salt and pepper before cooking to infuse the strands with flavor as they soften.
Placing the squash halves cut side up prevents them from getting too soggy as they won't be sitting directly in the water.
Start checking the squash at the 4-hour mark. Overcooking can make the strands mushy.
