I made some spaghetti and it turned out so good and super filling. One batch could last you the entire week! Chicken or turkey can be substituted for the ground beef. Try adding Italian herbs, like parsley, oregano, and fennel.

Recipe Ingredients

  • ¼ cup water
  • 1 spaghetti squash, halved lengthwise and seeded
  • 1 ½ pounds ground beef
  • 1 white onion, diced
  • 1 tablespoon extra-virgin olive oil
  • 1 cup sliced mushrooms
  • 1 zucchini, diced
  • 1 green bell pepper, chopped
  • 1 red bell pepper, chopped
  • 1 (14.5 ounce) can crushed tomatoes
  • 1 (8 ounce) can crushed tomatoes
  • ¼ cup chopped fresh basil, or to taste
  • ¼ cup chopped fresh oregano, or to taste
  • ¼ cup chopped fresh thyme, or to taste
  • 1 tablespoon red pepper flakes, or to taste
  • ½ cup extra-virgin olive oil, divided

Cooking Directions

  1. 1 Preheat oven to 400 degrees F (200 degrees C).
  2. 2 Pour water into a baking dish. Place squash halves with cut sides down in baking dish; roast for until tender, 30 to 40 minutes.
  3. 3 While squash is baking, cook and stir ground beef and onions in a skillet over medium-high heat until the beef is crumbly, evenly browned, and no longer pink. Drain and discard any excess grease. Set beef aside.
  4. 4 Heat 1 tablespoon olive oil in a skillet over medium heat; cook and stir mushrooms, zucchini, green and red bell peppers, both amounts of crushed tomatoes, basil, oregano and thyme. Simmer over medium heat until vegetables are cooked through and tender, about 10 minutes. Add the ground beef and onions; stir to combine. Simmer on low heat, stirring occasionally, while you finish preparing spaghetti squash.
  5. 5 Scrape the inside of hot spaghetti squash halves with a fork to shred the squash into strands; divide onto 8 plates. Drizzle each serving of spaghetti squash with 1 tablespoon extra-virgin olive oil and top each serving with a generous amount of meat sauce.

  1. This is a great recipe. So what if it is a bit bland... Don't give it a one star because you can't add flavor to your recipes.
  2. Absolutely amazing! My kids prefer this recipe over regular spaghetti sauce with meat and sausage in it. This is amazing on spaghetti squash or by itself. Its very tasty and easy to make. The flavors are wonderful!
  3. I added everything in the recipe minus the red pepper flakes. I cooked the onions by themselves in a tiny bit of olive oil to bring out the flavor the added to them to the cooked hamburger meat and seasoned with sea salt pepper and dried basil thyme and oregano. I then cooked the rest - Read more ...
  4. I used 1 pound of Bison and 1 pound of Veal and made meatballs. I added 4 garlic cloves salt and use whole peeled tomatoes and crushed them with my cavewoman's hand!!. I only put 2 teaspoons of red pepper flakes not 1 tablespoon I may use less next time. Very tasty!! I'm learning how - Read more ...
  5. I appreciate the ingredients, but something is missing... and it's not just salt. As a side note, the amount of salt I added to this dish is appalling. It needs something that would add depth and tie it all together, and I'm not sure what that ingredient is. As it stands now, the recipe is - Read more ...
  6. Relatively bland, but simple meal. I needed to use 2 spaghetti squash, not 1. Good leftovers. I've made better spag. squash paleo recipes, so I'd honestly skip this if you were considering.
  7. For a paleo diet dinner it was ok. But I agree that it's way too bland.
  8. More flavor was needed in this dish. The spaghetti squash is watery and bland and I will not buy again. The sauce made lots and I had to tweak it so I added some leftover spaghetti sauce garlic oregano italian seasoning and a little salt. The sauce then worked great served over spaghetti.
  9. The dish needed more flavor...garlic would have been a great addition.
