3 Simple Ingredients

  • Spaghetti Squash: Look for heavy, unblemished squash with an even golden color.
  • Fat: Butter, oil, or leftover bacon grease helps to caramelize the squash and add flavor.
  • Seasonings: Other than salt and pepper, try a mild Italian blend, a spicy adobo, or a zesty Cajun flavor to match the meal.

Holly’s Prep Tip

Before slicing the squash, pop it in the microwave for 3 to 4 minutes first to soften the outside and make cutting easier.

Just poke it a few times with a fork and do not cook it longer than 5 minutes, or it could build up pressure and pop!

How to Bake Spaghetti Squash

  1. Cut the squash in half vertically and remove the seeds and stringy fibers.
  2. Season the cut sides with butter or oil and desired seasonings.
  3. Bake cut-side down until tender.
  4. When cool enough to handle, separate the flesh into strands with a fork.

How Long to Bake?

Cooking times and temperatures vary based on the size of the squash, but here’s a general baking guide for a 1.5 to 2-pound spaghetti squash:

  • Bake at 425°F for 35-45 minutes
  • Bake at 400°F for 40-50 minutes
  • Bake at 375°F for 50-60 minutes
  • Bake at 350°F for 55-70 minutes

Holly’s Helpful Hints

  • You’ll know spaghetti squash is done when you can pierce the skin with a fork or knife easily.
  • Even though spaghetti squash can be cooked in the microwave, this method enhances its sweetness by caramelizing the edges.
  • I love to save the seeds for roasting; they taste just like my roasted pumpkin seeds.

Storing Leftovers

Keep leftovers in an airtight container in the refrigerator for up to 4 days or in the freezer for up to 6 months. Reheat in the oven or in the microwave and season as desired

  1. Delicious and easy. Definitely will make it again. I added fresh sliced mushrooms and butter on top. After removing vegetables and feta and shredding the spaghetti squash I returned all back into squash and spread fresh parmesean cheese and returned to oven for a few minutes.5 stars

  2. The spaghetti Squash looks delicious, I’m going to try this recipe. Thanks so much.❤️❤️❤️❤️❤️

  3. Very tasty and easy. Strands came out very easy and Had excellent texture. I will use this as my go to recipe from now on!!5 stars

  4. I have so many spaghetti squash left from the garden and couldn’t remember how to prepare them! This recipe was so easy and turned out delicious. I topped with butter once shredded and my kids absolutely loved it! SWP Employee5 stars

  5. My first time cooking Spaghetti Squash; so happy I found your recipe. I added Garlic Plus and it is really tasty good. Served with your Air fryer Chicken Breast that also came out fantastic.

  6. I love this recipe!! Thank you for sharing. I cook my squash for 20-25 minutes depending on size. First time I baked one, I overcooked the squash. Second time 5-10 minutes less and it was a little firm (Al dente) and it came out perfect! I made the best meat sauce spaghetti Served with cottage cheese and Caesar salad! I like my spaghetti spicy! Thai ground Chili 5 stars

  7. Spaghetti squash fibers wrap around the squash in such a way that cutting it lengthwise results in very short strands. If you want longer strands, cut it in half the other way.4 stars

    1. I always do it this way, cut across the short side and after it’s roasted gently slide a spoon around the entire outside, between the skin and the strands, and remove it in one piece for a spaghetti squash nest, it’s a really fun serving option!4 stars

  8. The Baked Spaghetti Squash came out excellent. Very quick & easy. Topped it with ground turkey, seasoned and added sauteed vegetables(sweet potatoes, cabbage, carrots, zucchini, spinach, mushrooms, red peppers).5 stars
