If you’ve ever tried cutting carbs but missed long twirls of pasta on your plate, chances are someone suggested spaghetti squash. This bright yellow vegetable has become a popular alternative for noodle lovers following low-carb and keto diets. But the big question people keep asking is: is spaghetti squash keto? The answer isn’t as simple as yes or no—it comes down to carb counts, portion sizes, and how you prepare it.

The first time I tried spaghetti squash, I was skeptical. I remember a friend serving it as a replacement for traditional pasta during a dinner party.

Why Spaghetti Squash is a Favorite Low-Carb Dish
A Simple Memory of Spaghetti Squash Dinners
When starting a keto lifestyle, the question quickly popped up: is spaghetti squash keto? Unlike zucchini noodles, which are ultra-low in carbs, spaghetti squash does contain more natural sugars. But its net carb content is still much lower than traditional pasta, which makes it a great “middle ground” option if you want something heartier than zucchini noodles but still within keto-friendly limits. It became my go-to vegetable for nights when I craved comfort food but wanted to stay on plan.
What Makes Spaghetti Squash Stand Out on Keto?
People often ask is spaghetti squash keto not just because of its carbs, but because it’s so different from other vegetables. The magic lies in the way it cooks: once baked or microwaved, the inside transforms into thin, noodle-like strands that naturally resemble spaghetti. Unlike cauliflower rice or zucchini noodles, spaghetti squash doesn’t taste watery or mushy. Instead, it has a slightly nutty, mildly sweet flavor that pairs well with almost any sauce or seasoning.
Its versatility is part of why spaghetti squash has earned such a spot in keto and low-carb kitchens. You can keep it light with herbs and olive oil, or make it hearty with a meaty Bolognese. It feels like comfort food without the carb crash. That’s why so many people consider it a “gateway veggie” for transitioning to keto-friendly meals—it satisfies those pasta cravings while keeping carbs in check.

Carb Count and Keto Compatibility
So, back to the big question: is spaghetti squash keto? To answer that, we need to look closely at the carb count. For keto, most people aim for a daily intake of around 20–50 grams of net carbs.
