The long, thin strands of spaghetti squash are perfect for pasta sauces, but they are also excellent when tossed with olive oil and seasoned with salt and pepper.


Uncooked onion(s)

1 medium, diced

Olive oil

1 tsp

Fresh tomato(es)

1 small, plum, seeded and diced

Canned tomato sauce

1 cup(s)

Ground oregano

¾ tsp

Table salt

½ tsp

Black pepper

¼ tsp

Uncooked spaghetti squash

1½ medium, or 1 large, about 5 pounds

Grated Parmesan cheese

¼ cup(s)


  1. In a nonstick skillet, sauté onion in oil until translucent, about 10 minutes. Add tomato, tomato sauce, oregano, salt and pepper and simmer over low heat for 30 minutes.
  2. Meanwhile, halve spaghetti squash lengthwise and remove seeds. Cover each half with wax paper, leaving 1 corner exposed. Microwave, cut side up, on a plate on high power for 8 minutes. Squash should separate easily into strands when done. Scrape out flesh and place in a large mixing bowl.
  3. Mix in tomato sauce and season to taste. Divide into six 2/3-cup portions and top each with 1 tablespoon Parmesan.
