If you’ve ever wondered if there’s an easy way to cook spaghetti squash, look no further. Microwaving is the fastest and easiest way to get those tender, noodle-like strands without heating up your oven.

Why Microwave Spaghetti Squash?

Spaghetti squash is a fan favorite in the world of healthy recipes. Its long strands mimic traditional spaghetti noodles without all the carbs. It’s packed with nutrients like vitamin C and is naturally gluten-free.

Microwaving is the best way to get dinner on the table faster. The cooking process is simple, mess-free, and perfect for beginners.

Tools You’ll Need

• Sharp knife
• Cutting board
• Microwave-safe glass baking dish
• Oven mitts
• Fork for fluffing strands

Ingredients

• 1 whole spaghetti squash
• ​1 inch of water in baking dish
• Toppings of your choice, such as oil, salt and pepper; freshly grated parmesan cheese; or pasta sauce 

Simple Steps to Microwave Spaghetti Squash

1. Wash the squash. Use water and a clean towel to remove any dirt from the outside of the squash.
2. Cut the squash in half lengthwise. Use a very sharp knife on a flat surface to safely cut the stem off the squash and then cut the squash in half from top to bottom lengthwise. 
3. Scoop out the seeds. Remove the seeds and stringy pulp from the middle of the squash with a spoon. 
4. Place the squash halves cut side down. Position each half flesh-down in a glass microwave-safe dish. The flesh of the squash should be touching the bottom.
5. Add one inch of water. This helps create steam inside the microwave.
6. Microwave on high for 20 minutes. Microwave times may vary slightly depending on the size of the spaghetti squash and the strength of your microwave oven. You know it’s done when you can easily pierce the flesh with a fork and get spaghetti-like strands when scraped. 
7. Let it cool. Use an oven mitt to remove the hot dish. Let the squash halves rest for a few minutes before handling.
8. Fluff with a fork. Turn the halves over and gently scrape the spaghetti-like strands from the flesh of the squash.
9. Season and serve. Add a little olive oil, parmesan cheese, or your favorite pasta sauce to complete the dish.

Tips for Success

• If you’re nervous about cutting, poke holes in the whole thing and microwave for 3–5 minutes first to soften. 
• Halving the squash lengthwise is easier if you first cut off the stem.
• A larger squash may need more cooking time. A small one might need less time.
• For storage, use an airtight container. Keep in the fridge for 3 to 4 days.

Different Ways to Use Spaghetti Squash

• Toss with pasta sauces like marinara or alfredo.
• Top with meatballs or sautéed vegetables.
• Mix with cheese and herbs for a simple casserole.
• Use instead of spaghetti noodles for a low carb meal.
• ​Use with stir fry. Instead of rice, use spaghetti squash. 
• Stuff the halved squash with a savory mixture of meat or beans, vegetables, and spices (similar to zucchini boats).

Frequently Asked Questions (FAQs)

• How long do you microwave spaghetti squash? Usually about 20 minutes, but the size of your squash affects the cook time.
• Can I microwave a whole spaghetti squash without cutting it? Probably, but I wouldn’t recommend it. Instead, slice it in half for even cooking and steaming.
• How do I store leftover spaghetti squash? Cool it first. Then keep it in an airtight container in the fridge for 3 to 4 days.
• What’s the best method for getting long strands? Cut across the width, not lengthwise. This preserves the spaghetti-like strands better. 
• Can I freeze cooked spaghetti squash? Yes, although it may have a softer texture when thawed. Store in freezer-safe bags, being sure to remove excess liquid. Press out extra air to prevent freezer burn.
• What size of the squash works best? Medium is ideal, but you can use any size. Just adjust the cooking time appropriately.
• Why is my squash watery? You may have added too much water. Stick with about an inch of water in the bottom.
• What’s the mild flavor of spaghetti squash like? It’s slightly sweet and very neutral – perfect with garlic, herbs, or spicy sauces.

Microwaving spaghetti squash is our preferred method because it’s fast, reliable, and mess-free. It’s the perfect way to prepare a healthy side dish without the fuss.

Try pairing it with your favorite sauce and a sprinkle of fresh basil or parmesan cheese. Spaghetti squash is super versatile, making it fun to experiment with toppings.

Microwaving squash may seem unconventional, but once you try this method, you might never go back to roasting. Cooking spaghetti squash in the microwave is truly one of the best hacks I’ve discovered. Hope you enjoy it as much as I do!
