Frequently Asked Questions About Spaghetti Squash with Meat Sauce

Spaghetti squash contains approximately 7 grams of net carbs per cooked cup — compared to 40+ grams in a cup of cooked pasta. This makes it one of the best low-carb pasta substitutes available for keto and low-carb diets.

Yes — spaghetti squash contains only 42 calories per cup compared to 220 calories in cooked pasta. It is high in water content and fiber, which promotes satiety. Replacing pasta with spaghetti squash in a standard serving reduces the carb and calorie content of a meal by over 70%.
