Kitchen Tools You Need To Make Microwave Spaghetti Squash

Microwaving spaghetti squash is so quick and easy! I cook vegetables in the microwave (for example, broccoli, asparagus, potato, sweet potato, corn, green beans) very often.  If my oven, Instant Pot and Air Fryer are taken up by other foods that are cooking in there, microwave is to the resque :)

How To Cook Spaghetti Squash In The Microwave

Cut the spaghetti squash in half using a sharp knife (a great knife would really make your life easier – click here for my knife recommendations).

Scoop out and discard the seeds.  Did you know that there is such a thing as pumpkin seed scraper? :) If you don’t have it, just use regular spoon!  If you cook squash a lot and want to make the task of scooping seeds easier, click here to get the seed scraper on Amazon – you’ll thank me :)

Put spaghetti squash halves in a microwave-safe 9×13 dish cut-side down and add 1 cup of water.

Put spaghetti squash in the microwave and microwave on High for 15 minutes, or until tender.  When done microwaving, carefully flip over the squash halves with tongs, so the cut side is up.

Separate the spaghetti squash into strands with a fork.

Season spaghetti squash with salt, pepper and your favorite seasonings and enjoy! I love it sprinkled generously with Parmesan cheese, and it’s also great with butter and maple syrup!

Serving Suggestions

• Toss the spaghetti squash with marinara sauce and Juicy Meatballs in the Air Fryer for a classic Italian-inspired meal.
• Drizzle with olive oil, sprinkle with Shredded Parmesan Cheese, and add a pinch of red pepper flakes for a simple yet flavorful dish.
• Pair it with Air Fryer Grilled Chicken Strips or Perfectly Baked Sockeye Salmon for a complete and healthy dinner.
• Serve it as a side dish alongside Rainbow Roasted Vegetables and a hearty protein.
• For a sweet twist, mix in a little butter, cinnamon, and a drizzle of maple syrup.

Tips For Success

• Cutting the Squash: Use a sharp, sturdy knife to cut through the tough skin of the spaghetti squash. If the squash is too hard to cut, pierce it with a fork and microwave for 2-3 minutes to soften slightly before slicing.
• Removing the Seeds: A spoon works well, but if you cook squash often, a pumpkin seed scraper can make the job quicker and easier.
• Microwave-Safe Dish: Ensure the dish you use is microwave-safe and large enough to fit the squash halves comfortably. A tight fit can affect even cooking.
• Cooking Time: Microwave times may vary depending on the size of your squash and the wattage of your microwave. Check for tenderness by piercing the squash with a fork.
• Avoid Overcooking: Overcooking can make the strands mushy. Aim for a tender yet firm texture that holds its spaghetti-like shape.
• Seasoning: Spaghetti squash has a neutral flavor, so don’t be shy with seasonings. Experiment with garlic powder, Italian herbs, or even a splash of balsamic vinegar for added taste.
• Safe Handling: Be cautious when removing the dish from the microwave, as it will be hot. Use oven mitts or a thick towel for safety.
• Serving Fresh: If possible, serve immediately after cooking for the best taste and texture. Reheated squash may lose some of its firmness.

Variations and Substitutions

• Herb-Infused Squash: Add fresh or dried herbs like rosemary, thyme, or basil before microwaving. This infuses the squash with aromatic flavors while it cooks.
• Cheesy Delight: Mix the squash strands with shredded mozzarella or cheddar cheese for a gooey, comforting dish. Parmesan or feta crumbles also make excellent additions.
• Garlic Butter Squash: Toss the cooked strands with melted butter, minced garlic, and a sprinkle of parsley for a savory side dish.
• Low-Carb Pasta Bowl: Use the spaghetti squash as a base for your favorite pasta toppings like marinara sauce, Alfredo, or pesto, making it a healthy alternative to traditional noodles.
• Sweet Squash Option: Turn it into a dessert-like treat by adding butter, brown sugar, and cinnamon. A drizzle of maple syrup can take it to the next level.
• Protein Boost: Combine with cooked ground turkey, chicken, or tofu for a filling, protein-packed meal. Add some veggies like spinach or bell peppers for added nutrients.
• Dairy-Free Alternative: Skip the cheese and butter and opt for olive oil, lemon juice, and nutritional yeast for a vegan-friendly option.
• Spicy Kick: Sprinkle with red pepper flakes or drizzle with sriracha for a bold, spicy flavor.

Storage and Reheating

• Storage: Place any leftover spaghetti squash in an airtight container and refrigerate. It will stay fresh for up to 5 days.
• Freezing: If you’d like to store it longer, freeze the squash strands in a freezer-safe container or bag. Make sure to remove as much air as possible to prevent freezer burn. It can be stored for up to 3 months.
• Reheating in the Microwave: Transfer the desired amount of squash to a microwave-safe dish, cover loosely with a microwave-safe lid or plastic wrap, and heat for 1-2 minutes or until warmed through.
• Reheating on the Stovetop: Heat a non-stick skillet over medium heat, add the squash with a bit of butter or olive oil, and stir until heated thoroughly.
• Avoid Overheating: Reheat just until warm to prevent the squash from becoming mushy.

Frequently Asked Questions

How do I know when the spaghetti squash is done cooking?

The spaghetti squash is done when you can easily pierce the skin with a fork and the flesh is tender. If you’re unsure, gently scrape the inside with a fork—if it forms spaghetti-like strands easily, it’s ready.

Can I cook a whole spaghetti squash in the microwave?

Yes, you can! Pierce the whole squash several times with a fork to allow steam to escape, then microwave it for about 8-12 minutes, depending on its size. Let it cool slightly before cutting it open and removing the seeds.

What’s the best way to cut a spaghetti squash?

Use a sharp knife and a stable cutting board to prevent slipping. If the squash is too tough to cut, microwave it for 2-3 minutes to soften the skin slightly. This makes slicing much easier and safer.

Can I add seasoning before microwaving the squash?

It’s best to add seasoning after cooking, as microwaving with seasonings might not evenly distribute the flavors. Once cooked, you can season the strands to your liking with salt, pepper, herbs, or sauces.

Is microwaving spaghetti squash safe?

Yes, microwaving is a safe and efficient cooking method for spaghetti squash. Be sure to use a microwave-safe dish and handle it carefully when removing it from the microwave, as it will be hot.

Can I make this ahead of time?

Absolutely! Cook the squash in advance, scrape it into strands, and store it in the fridge or freezer. Reheat it just before serving and add your preferred toppings or sauces.

What can I do with leftover spaghetti squash?

Leftovers are incredibly versatile! Use them as a base for stir-fries, add them to soups, or mix with eggs and cheese for a low-carb breakfast bake. You can also toss them with vinaigrette and veggies for a cold salad.
