Spaghetti Squash Marinara

Spaghetti Squash Marinara is the best gluten-free, low-carb spaghetti alternative with a yummy marinara sauce! Our kids love this recipe and have never complained that it isn’t “real” pasta. It’s just THAT delicious. 

At this time of year, the farmers’ markets are filled with all different varieties of winter squash. Most of them have a buttery, silky quality, but not spaghetti squash. After you bake spaghetti squash, you take a fork and scrape it out into what looks just like spaghetti. We made this recipe for a bunch of kids and they all yelled “spaghetti!” when they saw it. 

We were a little nervous they would turn their noses up when they realized it wasn’t pasta, but they totally dug it. Their moms were thrilled too because it is a vegetable, so we all chowed down together and enjoyed every bite!

Spaghetti squash is an oblong-shaped seed bearing squash that can be orange, yellow-hued or white, and is rich in folic acid, potassium, vitamin A and beta carotene. It’s also low in calories (about 75 for every 8 ounces cooked).

This is a perfect inexpensive dish that’s also great for kids’ school lunches. It’s yummy warm or cold, so make plenty to have for leftovers!
