Ingredient Notes

This section provides a quick rundown of the ingredients used when baking spaghetti squash and also in our spaghetti squash recipe. For complete measurements and step-by-step instructions, please scroll to the recipe card located at the bottom of this post.

For The Baked Spaghetti Squash

  • Spaghetti Squash: Look for a squash that is firm to the touch, without any soft spots, and feels heavy for its size. The stem should be dry and intact. Keep your uncooked squash in a cool, dry place, and it should stay fresh for about a month.
  • Olive Oil: Extra virgin olive oil is preferred due to its rich flavor and high nutrient content, as it undergoes minimal processing. It adds a distinct, authentic olive taste to the dish. However, for a milder flavor, feel free to use light olive oil.
  • Salt and Black Pepper: These classic seasonings are key for enhancing the natural taste of the squash.

For The Spaghetti Squash Recipe

  • Butter: Salted butter is used to enrich the dish with its creamy flavor.
  • Garlic: Use thinly sliced garlic to infuse the squash with a warm, aromatic quality.
  • Parmesan Cheese: Whenever possible, opt for freshly grated Parmesan cheese to add a sharp, salty finish to the dish.

How To Cut Spaghetti Squash Safely And Effectively

For prepping your spaghetti squash, here’s what you’ll need:

  • A sturdy chef’s knife
  • A towel for drying and stabilizing the squash
  • A cutting board
  1. Prep the Squash:
    • Select an oval-shaped spaghetti squash, which is easier to slice into.
    • Wash and dry the squash completely to ensure a safe, slip-free cutting process.
    • Position the squash on a sturdy cutting board.
    • With a sharp chef’s knife, trim off the stem and the bottom ends of the squash to create stable, flat cutting surfaces.
  2. Cutting and Cleaning:
    • Stand the squash upright on one of the flat ends and slice it down the middle lengthwise.
    • Use a spoon to remove the seeds from each half, leaving a clean cavity ready for cooking.

How To Cook Spaghetti Squash

  1. Preheat and Prepare: Set your oven to 400 degrees F (200 degrees C). Take the spaghetti squash halves and place them on a baking sheet with a heavy base. Drizzle 1 tablespoon of olive oil over each half. Season with a pinch of salt and pepper.
  2. Rub the oil and seasoning over the inside and outside skins of the squash for even flavor.
  3. Bake: Turn the squash halves cut side down on the baking sheet. Cover the sheet with aluminum foil to create a steamy environment for even cooking. Place the baking sheet in the oven. Bake until the outer shell feels soft to the touch, which should take about 45-50 minutes, but this may vary if your squash is particularly large or small.
  4. Cool and Shred: Once baked, remove the squash from the oven and let it cool enough to be handled safely. Use a fork to gently scrape out the squash flesh into strands that look like noodles. Enjoy your spaghetti squash as a delicious, low-carb alternative to pasta.

Frequently Asked Questions

How Can I Tell If Spaghetti Squash Is Fully Baked?

To check if your spaghetti squash is fully cooked, press the skin with your finger—it should be soft and give way under pressure. Be cautious; the squash will be very hot. If the skin doesn’t dent and feels hard, continue to bake it for a few more minutes.

What’s The Best Way To Store Spaghetti Squash After Cooking?

Once cooked, spaghetti squash should be stored in a sealed container in the fridge, where it will keep for up to one week. For longer storage, it can be frozen for up to three months.

Is It Possible To Cook Spaghetti Squash In A Slow Cooker?

While baking is my preferred method for a crispier texture, cooking spaghetti squash in a slow cooker is possible. Here’s how to do it:
Clean the squash thoroughly and dry it. Make several small punctures in the squash with a fork to allow steam to escape.
Place the squash in a large slow cooker. For a 3-pound squash, cook on high for 3-4 hours or on low for 5-6 hours. Add one additional hour of cooking time for each pound over 3 pounds.
After cooking, carefully remove the squash from the slow cooker. Let it cool until it’s manageable, then cut it open, remove the seeds, and use a fork to shred the flesh into strands, as shown in the guide images.

Expert Tips

  • Sharp Knife for Cutting: Employ a large, sharp knife for slicing through the spaghetti squash. Position the squash on a stable cutting board, trim off both ends, then cut down the middle. Should the knife become lodged, start again from the initial cut and slice from the opposite direction for ease.
  • Additional Cooking Time: Should the spaghetti squash still be firm after the initial baking time, don’t hesitate to place it back in the oven. Continue to bake until it reaches the desired tenderness.

  1. This was so easy and the spaghetti squash was very tasty. Thank you for the wonderful recipes, this is a delightful place to find new and interesting cooking challenges.

  2. First time making spaghetti squash. Easy recipe, used Cabot 5 cheese Italian shredded cheese. Very tasty. Thanks for sharing 😊

  3. Hi this will be my first time trying the recipe, I can’t wait! A bit of clairfication, please Your description says heat the oven to 400f but the actual recipe say 375? What do you suggest?

  4. Have you tried baking the squash whole and just poking it like you would a baked potato? I baked my spaghetti squash like that at 350 for about 45-50 min and turning over half way through.
    After I let it rest, I cut it in half then scooped out the seeds and stuff. Then I was able to get almost all of the squash out, down to the skin. And it was still that crunchy, nutty flavor that is spaghetti squash and not over cooked, baby food!

  5. It’s my first time baking spaghetti squash and I’m so glad you mentioned consistency in a previous comment. I searched everywhere looking for it and no one bothers to mention it. I popped my spaghetti squash back in the oven after realizing it was probably under cooked. Thank you for your comments!!!!

  6. I’m making spaghetti squash chow mein today but I’ve never worked with it so I was thrilled to stumble across your post. So helpful!!

    1. Lesa,
      The texture of spaghetti squash will not be as soft as regular pasta. There will always be a slight crunch to the spaghetti squash. You will know that the squash is completely cooked if there is a little “give” to the rind of the squash when you press on it and when the strands pull away from the rind easily. If your squash isn’t completely cooked after 45 minutes, I would recommend leaving the squash in the oven, covered for an additional 10 minutes to cook. Hope this helps.

  7. I am the only one who eats spaghetti squash in my house. They are too large to eat the whole squash. Can I save half uncooked and covered in the fridge? If so, how long do you think it will last?

    1. Hi Andrea, you can save the other half of the spaghetti squash by wrapping it in plastic wrap and storing it in the fridge. It’ll stay good for a few days. What I have done in the past is cooked up the entire spaghetti squash and stored the remaining portion in the freezer. To do this, portion the spaghetti squash into smaller containers and when you want to eat it, defrost the squash and then heat it in a skillet with a little olive oil and flavor it with herbs and parmesan cheese. You will find that the squash will be watery when defrosted but by warming it in the skillet, the water will evaporate.

  8. Your recipe for spaghetti squash sounds so easy, I am looking forward to cooking it. This will be my first attempt with this squash. So thank you for your help.

    1. Thanks, Susan. It’s such an easy vegetable to cook, the hardest part is cutting it down the middle. I’d love to know how you prepared your spaghetti squash.
