  • 1 spaghetti squash
  • 1 14.5 ounce can fire roasted tomatoes, drained well
  • ½ cup marinara sauce *
  • ¾ cup mozzarella cheese *, divided
  • extras: fresh basil, dried basil or Italian seasoning, garlic powder & parmesan cheese!


  • Preheat the oven to 375 degrees.  Line a baking sheet with foil.  Spray it with cooking spray.
  • Carefully pierce the whole spaghetti squash with a sharp knife.  Put the squash in the microwave for 3-5 minutes or until it is easier to cut.  Carefully slice it in half.
  • Place the squash flesh side down on the baking sheet.  Bake for about 45 minutes or until the squash is tender and comes apart in spaghetti-like noodles easily.  It will take a little more time for a larger squash and little less for a smaller one.
  • When the squash is cooked flip it over and carefully remove the seeds.  Use a fork to separate the squash being careful to leave a little around the edges and to not hurt the squash boat.  Put all of the noodles in a bowl.
  • Add the canned tomatoes to the spaghetti squash.  Add a little bit of marina sauce until you have enough to cover all your noodles.  The exact amount will vary due to the variable size of spaghetti squash.  Toss ½ cup of the cheese.  If you want to be creative also add fresh or dried basil, garlic, and parmesan cheese.
  • Refill the squash halves with the marinara mixture.  Sprinkle the top with the remaining mozzarella cheese.
  • Bake for 7-9 minutes or until the cheese on top is melted.  To get a golden brown color you can turn to oven up to broil for a few minutes.  Just be careful not to burn the squash.


*The exact amount of sauce and cheese will vary due to the size of your squash.  Just add enough until the noodles are covered but not soggy.
