What You’ll Need

• ▢14 pound spaghetti squash
• ▢1cupwater,may more be needed
• ▢Kosher salt,to taste
• ▢Black pepper,to taste

Prep Tips Before You Start

Choose a firm spaghetti squash without soft spots. A 14 pound squash in this recipe might sound large—make sure you have a microwave-safe dish big enough to hold the squash halves and water. You’ll also want a sharp knife, a large spoon for scraping the strands, and an oven mitt or towel for handling hot dishes.

Step-by-Step: How to Cook Spaghetti Squash in the Microwave

Follow these steps exactly to get even, tender strands every time.

1. Wash and dry the squash. Rinse the outside of the squash under cool running water and pat it dry. This removes any dirt and makes cutting safer.
2. Cut the squash in half lengthwise. Place the squash on a sturdy cutting board. Using a sharp chef’s knife, cut the squash from stem to tip to create two long halves. If the squash resists, press down firmly and rotate the squash as needed until you have two even halves.
3. Scoop out the seeds. Use a large spoon to scrape the seeds and stringy bits from the center of each half. Discard the seeds or reserve them for roasting later.
4. Arrange in a microwave-safe dish. Place the squash halves cut-side down in a microwave-safe baking dish or deep plate. Make sure they fit comfortably without overlapping.
5. Add the water. Pour 1 cup of water into the dish around the squash halves. The water creates steam that helps cook the flesh evenly. If your dish is particularly large or the squash is very thick, you may need a bit more water; add just enough to create steam but not so much that it splashes when you remove the dish.
6. Microwave on high. Place the dish in the microwave and cook on high power. Start with 12 minutes for a squash of average thickness. If your squash is particularly dense, increase the time in 2–3 minute increments until the flesh is tender when pierced with a fork.
7. Check for doneness. Carefully remove the dish from the microwave using an oven mitt. Turn the halves over so the cut side is facing up. Pierce the flesh with a fork; it should slide through easily and separate into strands with a little scraping. If the flesh still feels firm, return to the microwave and continue cooking in short bursts.
8. Season and shred. Once cooked, sprinkle the interior with Kosher salt and black pepper to taste. Use a fork to gently rake the flesh lengthwise to release the spaghetti-like strands into the shell.
9. Serve or use in a recipe. Transfer the strands to a serving bowl or use them directly in your favorite sauce or topping. Taste and adjust seasoning as needed.

Timing Notes

Microwave wattages vary, so cooking time can change. As a starting point, plan on 12–15 minutes for a large squash; check at 12 minutes and add 2–3 minute intervals if needed. The squash is done when the flesh separates into long strands easily with a fork.

Flavor and Serving Ideas

Spaghetti squash is a blank canvas. After following the How to Cook Spaghetti Squash in the Microwave steps above, you can:

• Toss with a simple olive oil, garlic, and lemon juice dressing for a bright, light side.
• Top with your favorite tomato sauce and a sprinkle of grated cheese for an easy weeknight “pasta.”
• Sauté mushrooms, spinach, and onions in a little oil, then fold into the strands for a veggie-forward main.
• Mash in a dollop of pesto and toasted pine nuts for an herby twist.

Storage and Reheating

Cooked spaghetti squash keeps well. Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave for 1–2 minutes, stirring halfway through, or warm gently on the stovetop in a pan with a splash of water or oil to refresh the texture.

Common Questions

My squash came out watery. What happened? If the squash is overly wet, it may have been slightly overcooked or cooked with too much water in the dish. Reduce the cooking time by a minute or two next time, and use only as much water as needed to create steam.

How can I tell when it’s done? The easiest test is the fork test. The flesh should be tender and pull apart into long strands easily. If the fork meets resistance, microwave a little longer.

Can I microwave smaller or larger squashes? Yes. Adjust the time: smaller squash needs less time, larger squash needs more. Always check for doneness and increase cooking time in short increments to avoid overcooking.

Why This Recipe Works

This approach focuses on steam to cook the squash evenly, preserving moisture and producing the distinct strands people love. The minimal seasoning—Kosher salt and black pepper—lets the squash shine while keeping the result versatile for many dishes. The directions are straightforward, making this a method you’ll come back to again and again.

This version of How to Cook Spaghetti Squash in the Microwave keeps the process simple and stress-free. With just a few minutes of active work and a short stint in the microwave, you’ll have a nutritious base that’s ready to adapt to any meal plan.

Ingredients

  

• 1/4 lb spaghetti squash
• 1 cup water more as needed to reach about 1 inch in the dish
• kosher salt to taste
• black pepper to taste

Equipment

• 9×13-inch microwave-safe glass baking dish (or two 8×8-inch dishes)
• Cutting Board
• Sharp chef’s knife
• Spoon
• Fork

Method

 

1. Wash the squash and place it on a cutting board; carefully cut it in half lengthwise using a sharp knife.
2. Scoop out and discard the seeds and stringy bits from each half with a spoon.
3. Place the squash halves cut-side down in a 9×13-inch microwave-safe glass dish; if your dish is smaller, use two 8×8-inch dishes or cook halves separately.
4. Pour about 1 cup water into the dish so there is roughly 1 inch of liquid; add more water if needed to reach that level.
5. Microwave on high for 10–15 minutes, testing after 10 minutes by piercing with a fork; total time depends on squash size and microwave wattage.
6. The squash is done when a fork easily pierces the skin and the flesh shreds into noodle-like strands.
7. Carefully remove the hot dish from the microwave, turn the squash halves cut-side up, and use a fork to shred the flesh into strands; season with kosher salt and black pepper to taste.

Notes

• Be very careful when cutting the squash in half; use a stable cutting surface.
• Start checking doneness at 10 minutes to avoid overcooking.
• Cooking time varies by microwave wattage and squash size.
• If your microwave can't fit a 9×13 dish, cook halves separately in an 8×8 dish.
• Use a fork to test and shred the flesh into noodle-like strands.
