Ingredients

1 Spaghetti Squash (medium size)

1/2 – 1 cup pasta sauce (adjust according to preference)

1/2 – 1 cup shredded mozzarella cheese (adjust according to preference)

Salt & Pepper (to taste)

leaves Optional: fresh garlic (fresh chopped basil , dried oregano or Italian seasoning)

Instructions

1

Preheat oven to 375 degrees F. Line a baking sheet with parchment paper or grease with olive oil or cooking spray.

2

With a sharp knife, carefully cut spaghetti squash in half lengthwise. With a spoon, gently remove seeds and discard. Place spaghetti squash cut side down on baking sheet. Bake for 45 minutes or until a fork can pierce the shell easily.

3

Remove from oven and allow to cool slightly. With a fork, loosen and separate spaghetti squash strands from shell. Reserve shells.

4

Place strands in a bowl. Mix strands with pasta sauce (and additional spices, if you wish). Adjust the amount of sauce you use based on your own preference. Spoon mixture back into the empty shell. If you have enough strands, you may be able to separate the mixture into each of the two shells, but you may also be able to spoon the entire mixture into just one of the shell halves. Sprinkle with mozzarella cheese.

5

Bake for 7-9 minutes or until cheese is melted, bubbly, and slightly browned. Spoon and serve directly from shell.

Key Points About Ingredients:

• Spaghetti squash is a nutrient-dense, low-carb alternative to pasta, naturally rich in fiber, vitamin C, and B vitamins while being very low in calories.
• Choose a pasta sauce with no added sugar and low sodium to keep this dish as wholesome as possible — a simple marinara works beautifully.
• Shredded whole-milk mozzarella melts more evenly and develops better browning than part-skim, giving you that irresistible bubbly, golden topping.
• Fresh basil or Italian seasoning added to the sauce mixture elevates the flavor dramatically without adding calories or complexity.
• Using the squash shell as the serving vessel makes presentation effortless and reduces dishwashing — a perfect weeknight dinner hack.

Key Nutritional Insights:

• Spaghetti squash is naturally very low in calories and carbohydrates compared to traditional pasta, making this dish a smart choice for those watching their carb intake.

• This dish provides a meaningful amount of vitamin C, primarily from the spaghetti squash, which supports immune function and skin health.
