Editor: Arshita Tiwari on May 26,2025

Spaghetti squash has earned its place as a favorite among health-conscious eaters, low-carb lovers, and veggie enthusiasts. It’s a versatile, mildly flavored gourd that, when cooked, shreds into strands resembling spaghetti — hence the name. Whether you're new to cooking this unique squash or just looking for a better method, this comprehensive guide covers how to cook spaghetti squash using both oven and microwave techniques.

We'll explore each method step-by-step, including tips on how to cut spaghetti squash, understanding spaghetti squash cooking time, and even throw in a simple spaghetti squash recipe to get you started.

Why Cook Spaghetti Squash?

Before starting to cook, let’s look at why so many people choose spaghetti squash.

• Low calorie and low carb-containing
• Excellent in fiber and provides important vitamins such as vitamin C, vitamin B6 and manganese
• A gluten-free way to replace regular pasta
• Naturally vegan and paleo-friendly

After seeing the benefits, let’s explore the process of making tasty spaghetti squash.

How to Cut Spaghetti Squash (Safely!)

Thankfully, handling spaghetti squash isn’t as difficult as it looks and you can do it safely with the proper tools.

The Equipment You’ll Use:

• A big, pointy chef’s knife
• A board designed for knife use
• A spoon to scoop the seeds.
• Alternative: You could use a kitchen towel or a microwave if you don’t have a hairdryer.

Steps:

• Secure the squash: Cut it with the length going on the cutting board. If your cake is still moving, carefully trim a flat base from the bottom with a little bit of cake.
• Remove the ends: Cut off both the top of the stem and the base to give the plant the right support.
• Slice Lengthwise: Holding the squash firmly, slice it from top to bottom, just as you would a melon. If you find the squash is very firm, pierce it a few times with a knife and place it in the microwave for 3–5 minutes to just improve its texture.
• Scoop the seeds: Use a spoon to get out the seeds and parts of the stringy flesh from inside the pepper.

Once you’ve done that, you’ll be ready for the oven or microwave method.

Method 1: Roasted Spaghetti Squash in the Oven

How to Roast Spaghetti Squash the Easy Way

Roasting is a great way to bring out the natural sweetness and slightly nutty flavor of spaghetti squash. It gives the strands a firm yet tender bite — perfect for pairing with sauces or enjoying simply with a bit of seasoning.

What You’ll Need:

• 1 medium spaghetti squash
• Olive oil
• Salt and pepper (as per taste)
• Optional: Garlic powder, dried herbs, or a sprinkle of Parmesan

Step-by-Step Instructions:

1. Heat Your Oven

Start by preheating your oven to 400°F (about 200°C). For easy cleanup, line a baking tray with parchment paper or foil.

2. Prep the Squash

Slice the squash in half lengthwise and scoop out the seeds. Place the halves on your tray with the inside (cut side) facing up. Drizzle with olive oil, then add salt, pepper, or any other seasoning you like. Now, flip the halves so the cut side faces down — this helps it cook evenly and steam from within.

3. Let It Roast

Bake in the oven for 35 to 45 minutes. The exact time depends on the size of your squash. Smaller ones might be ready in 30 minutes, while larger ones may take up to 50. It’s done when the skin gives slightly when pressed and a fork easily pierces the outer layer.

4. Cool and Scrape

Once roasted, take the squash out and let it cool for a few minutes. Flip the halves over and use a fork to gently pull the flesh into strands. You’ll see them naturally turn into noodle-like ribbons — just like spaghetti!

Method 2: Microwave Spaghetti Squash (Quick & Easy)

Short on time? The microwave method is your best bet. It’s fast, easy, and gives you soft, flavorful squash noodles in under 15 minutes. While the strands may be a bit softer than roasted ones, they’re still great for any quick meal.

You’ll Need:

• 1 medium spaghetti squash
• A sharp knife or fork
• A microwave-safe bowl or dish with a lid or plastic wrap

Step-by-Step Guide:

1. Get the Squash Ready

If you're okay cutting it, slice the squash lengthwise and remove the seeds. Want to skip the knife? Just poke a few holes all around a whole squash using a fork — this lets steam escape while cooking.

2. Microwave It

Put the squash (cut side down) into your microwave-safe dish. Add about half an inch of water. Cover with a microwave-safe lid or loosely with plastic wrap.

Here’s a quick timing guide for microwave spaghetti squash cooking time:

• Halved squash: Cook on high for 10 to 12 minutes.
• Whole squash: Heat for 12 to 15 minutes. Flip it halfway through so it cooks evenly.

To check if it’s done, poke the outside — it should feel soft, and a fork should easily go through.

3. Let It Cool and Fluff the Strands

Once cooked, let the squash sit for a few minutes — it will be hot! If you microwaved it whole, cut it open carefully. Then, grab a fork and gently pull at the inside. You’ll see the flesh separate into thin, noodle-like strands.

Simple Spaghetti Squash Recipe (Garlic Butter Version)

I’ve come up with a simple, tasty way to let everyone enjoy the flavor of spaghetti squash.

Ingredients:

• 1 single roasted or microwaved spaghetti squash
• 2 tablespoons you can use butter or olive oil
• Minced garlic from 2 cloves
• Add the required amount of salt and pepper.
• 1 tablespoon of chopped parsley
• You can add Grated Parmesan if you like (it is optional).

Directions:

• If using an oven, roast the squash uncovered for 40 to 45 minutes; if you choose the microwave, poke holes in the squash and cook it uncovered for 15 to 17 minutes.
• In the skillet, melt butter as it heats up over medium heat. After adding the garlic, cook it until it becomes fragrant (takes about 1 minute).
• Add the squash strands and stir to make sure they taste of the garlic butter.
• Add salt, pepper and some parsley.
• Top with Parmesan and bring it to the table when it is still warm.
