How to Cook Spaghetti Squash (Step-by-Step)

Cooking spaghetti squash is simple, but a few tricks will help you get perfect, tender strands every time.

Step 1: Prep the squash

Wash the spaghetti squash and dry it well.
Using a sharp chef’s knife, carefully cut it in half lengthwise. (Tip: If the squash is too tough, microwave it whole for 2–3 minutes to soften the skin.)
Scoop out the seeds with a spoon.

Step 2: Season and bake

Preheat your oven to 375°F (190°C).
Brush the inside of each half with olive oil and sprinkle lightly with salt and pepper.
Place the squash halves cut-side down on a parchment-lined baking sheet.
Roast for 35–40 minutes, or until the flesh is fork-tender.

Step 3: Shred the “noodles”

Let the squash cool for 5 minutes, then use a fork to gently scrape out long, noodle-like strands.
Transfer the strands to a bowl and fluff them up with a fork.

Alternative Cooking Methods

Microwave: Place squash halves cut-side down in a microwave-safe dish with ½ inch of water. Cover and cook for 10–12 minutes until tender.
Instant Pot: Cook squash halves on the trivet with 1 cup of water for 7–8 minutes at high pressure, quick release.
Air Fryer: Place halves cut-side down in the basket at 375°F for 20–25 minutes.

These methods are great if you’re short on time or want to avoid turning on the oven.

How to Make This Spaghetti Squash Recipe

Once your spaghetti squash is cooked and shredded into tender strands, it’s time to bring the whole dish together with fresh vegetables, herbs, and cheese.

Step 1: Sauté the aromatics

Heat 2 tablespoons of olive oil in a skillet over medium heat.
Add the chopped onion and cook until softened, about 4–5 minutes.
Stir in the garlic and cook for another 1 minute, being careful not to burn it.

Step 2: Add the tomatoes and olives

Stir in the diced tomatoes and sliced black olives.
Cook for 5–7 minutes, until the tomatoes break down into a light sauce.
Season with a pinch of salt and pepper.

Step 3: Combine with spaghetti squash

Transfer the shredded spaghetti squash strands to a large bowl.
Pour the tomato mixture over the squash and gently toss until everything is evenly coated.

Step 4: Finish with herbs and cheese

Sprinkle in the fresh basil and crumbled feta cheese.
Toss lightly and adjust seasoning to taste.

The result is a warm, flavorful dish that’s light yet satisfying — perfect as a vegetarian main course or as a side dish alongside grilled chicken or fish.

Cooking Time Guide

The time it takes to cook spaghetti squash depends on the method you choose. Here’s a quick reference so you can pick what works best for your schedule:

Oven Roasting: 35–40 minutes at 375°F (190°C). This method develops the best flavor and slightly caramelized edges.
Microwave: 10–12 minutes total. Fast and convenient, though the texture is a little softer than oven-baked.
Instant Pot: 7–8 minutes on high pressure, quick release. Great for meal prep when you want tender squash in a hurry.
Air Fryer: 20–25 minutes at 375°F. Produces a roasted texture without heating up the whole kitchen.

No matter which method you use, you’ll know your spaghetti squash is ready when the flesh is fork-tender and pulls apart into long, noodle-like strands.

Serving Suggestions

One of the best things about this spaghetti squash recipe is how versatile it is. You can enjoy it as a light main dish, a flavorful side, or even as a pasta substitute. Here are some tasty serving ideas:

As a vegetarian main course: Serve it topped with extra feta or mozzarella for a hearty, meatless dinner.
Alongside grilled meats or fish: Its mild, slightly sweet flavor pairs well with chicken, salmon, or steak.
As a pasta alternative: Swap traditional pasta with spaghetti squash in dishes like creamy sauces, pesto, or tomato-based recipes. Try using it in place of noodles in recipes such as pappardelle pasta or this savory casarecce pasta.
Mediterranean-style bowl: Keep it simple with olives, basil, and feta for a fresh, Greek-inspired meal.
Kid-friendly option: Top with marinara sauce and a sprinkle of Parmesan — it looks and tastes like spaghetti but is far lighter.

This recipe can easily adapt to whatever you’re craving, making it a staple for weeknight dinners and healthy meal prep.

Storage and Reheating Tips

Spaghetti squash stores well, making it a great option for meal prep or leftovers. Here’s how to keep it fresh:

Refrigeration: Store cooked spaghetti squash in an airtight container in the fridge for up to 4 days. Keep the vegetable mixture and cheese separate if possible for best texture.
Freezing: You can freeze cooked spaghetti squash strands for up to 3 months. Spread them on a baking sheet to freeze individually, then transfer to freezer bags. Note: the texture may be slightly softer after thawing.
Reheating: To warm up leftovers, heat them in a skillet over medium heat with a drizzle of olive oil, or microwave in 1-minute bursts, stirring between each interval. For larger portions, reheat in the oven at 350°F until hot.

With these tips, you can make this recipe ahead of time and enjoy healthy, ready-to-eat meals all week long.

Recipe Variations and Substitutions

This spaghetti squash recipe is highly flexible, so you can adjust it to fit your taste preferences or what you have on hand:

Cheese swaps: Use mozzarella for a melty texture, Parmesan for a nutty bite, or goat cheese for a tangy twist.
Fresh herbs: Try parsley, oregano, or thyme in place of basil for different flavor profiles.
Extra vegetables: Add sautéed zucchini, bell peppers, spinach, or mushrooms for more nutrition and color.
Protein boost: Mix in cooked chicken, shrimp, or chickpeas to turn this dish into a heartier main course.
Spicy kick: Sprinkle in red pepper flakes or drizzle with hot sauce for extra heat.

By experimenting with toppings and seasonings, you can make this recipe new and exciting each time you prepare it.

Expert Tips for Success

A few small tricks will help you get the best results every time you make this spaghetti squash recipe:

Cut safely: If the squash is hard to cut, microwave it whole for 2–3 minutes to soften the skin before slicing.
Avoid watery squash: Roast it cut-side down on a baking sheet so excess moisture can release while cooking.
Don’t overcook: Test doneness by gently scraping with a fork. If the strands pull apart easily but still hold shape, it’s ready.
Use fresh herbs at the end: Adding basil or parsley after cooking keeps the flavors bright and fresh.
Season generously: A light drizzle of olive oil, salt, and pepper enhances the natural sweetness of the squash.

Following these tips ensures your spaghetti squash comes out tender, flavorful, and never mushy.
