"A healthy low-carb dish every one likes. I have taken it to pot-lucks and people love it. Ground beef or Italian sausage can be added. I have even used leftover spaghetti sauce in this."
1Preheat oven to 400 degrees F (200 degrees C). Spray a 9x13-inch baking dish with cooking spray.
2Pierce spaghetti squash in several places with a knife. Microwave on medium-high, rotating every 5 minutes, until tender, 10 to 15 minutes. Remove from microwave. Let cool until easily handled, 5 to 10 minutes.
3Cut squash in half and scoop out seeds. Scrape insides of squash into spaghetti strands with a fork. Transfer to the greased baking dish.
4Pour tomatoes, 3/4 cup Parmesan cheese, oregano, basil, garlic, and salt over spaghetti squash; mix well. Sprinkle remaining 1/4 cup Parmesan cheese on top.
5Bake in the preheated oven until golden and bubbly, 45 to 60 minutes.
