Instant Pot Spaghetti Squash: The 7-Minute Wonder

My journey with spaghetti squash began with a generous gift from a relative’s garden. Determined not to let anything go to waste, I decided to explore the hype around “stuffed spaghetti squash noodles.” And let me tell you, I am now a total convert! The Instant Pot revolutionized how I prepare this amazing vegetable, making it incredibly fast and simple.

While there are several methods to quickly soften the inside flesh of a spaghetti squash, the pressure cooker undeniably stands out as the easiest and fastest. You can use any brand of electric pressure cooker you own; my preferred Instant Pot delivers consistent results, but popular alternatives like the Ninja Foodi and Crockpot Express also work wonderfully.

Ninja Foodi Spaghetti Squash: Pressure Cooking & Air Frying Combined

Just like the Instant Pot, the Ninja Foodi excels at pressure cooking spaghetti squash, offering the same speedy and tender results. The squash pictured above was fresh from the garden, but you can readily find high-quality spaghetti squash in grocery stores year-round. Once you experience the convenience of pressure cooking, you’ll wonder how you ever managed without it!

To ensure it fits comfortably in a 6-quart pressure cooker, aim for a spaghetti squash around 3 pounds, ideally no larger than 4 pounds. The goal is to cook the squash until it’s easily pierced and the “pasta” can be scraped out with just a fork. If you encounter resistance, it simply needs a bit more cooking time. Cutting the squash in half lengthwise before cooking is crucial for allowing the steam to properly penetrate and tenderize the inner flesh, resulting in those perfect, spaghetti-like strands.

Instant Pot Spaghetti Squash Cooking Time & Steps

The cooking time for spaghetti squash in the Instant Pot is incredibly quick, typically just 7 minutes for a 3-4 pound squash. This timing ensures perfectly tender noodles without overcooking. Here’s a detailed breakdown of the steps:

1. Prepare the Squash: Carefully slice the spaghetti squash in half lengthwise. Using a spoon, scoop out all the seeds and the stringy pulp from the middle, much like you would with a pumpkin. Ensure the interior is clean.
2. Set Up the Instant Pot: Place a trivet inside the bottom of your Instant Pot. Pour 1.5 cups of water into the pot. This water will generate the steam needed to cook the squash.
3. Arrange the Squash: Place both halves of the prepared spaghetti squash onto the trivet, with the cut sides facing up. Try to minimize overlapping to allow for even steaming.
4. Pressure Cook: Secure the lid on your Instant Pot and ensure the steam release valve is set to the sealing position. Set the pressure cooker to Manual or Pressure Cook (High) for 7 minutes.
5. Release Pressure: Once the cooking cycle is complete, perform a quick release of the pressure by carefully moving the steam release valve to the venting position. Be cautious of the hot steam.
6. Cool and Scrape: Once the pressure has fully released and the float valve drops, open the lid. Carefully remove the squash halves from the pot and place them on a cutting board. Allow them to cool for a few minutes to handle safely.
7. Create Noodles: While holding one half of the squash with an oven mitt (if still warm), use a fork to gently scrape the cooked flesh from the shell. It should easily separate into distinct, spaghetti-like strands.
8. Drain Excess Liquid: Transfer all the scraped spaghetti squash noodles into a bowl. You might notice some accumulated liquid at the bottom of the bowl; drain this liquid thoroughly to prevent soggy “pasta.”
9. Serve and Enjoy: Now your tender spaghetti squash noodles are ready to be dressed! Add your favorite spaghetti sauce, a generous sprinkle of parmesan or mozzarella cheese, and any other seasonings you desire. You can enjoy it directly from the bowl, or for an extra special presentation, use the empty squash halves as natural bowls.
10. Optional: Stuffed and Baked/Air Fried: To make “stuffed” spaghetti squash, fill the empty halves with the sauced noodles, top with more cheese, and bake in an oven at 375 degrees Fahrenheit for about 10 minutes, or until the cheese is melted and bubbly. Alternatively, use an air fryer lid (if you have one) at 400 degrees Fahrenheit for approximately 5 minutes for a quick melt and slight crisp.

Unlike traditional spaghetti, these squash noodles are typically shorter, which actually makes them much easier and more enjoyable to eat!

Serving Pressure Cooker Spaghetti Squash: Endless Possibilities

Here’s the exciting part: when you use spaghetti squash noodles as an alternative to traditional pasta and load it with your favorite sauces and cheeses, you genuinely cannot tell the difference! I was incredibly surprised myself, and now spaghetti squash is a beloved staple in our home. Its mild flavor readily absorbs whatever delicious toppings you add, making it a fantastic canvas for countless meals.

Here’s a popular way we prepare it to mimic classic spaghetti:

• After expertly scraping out the tender spaghetti squash strands, transfer them to a large mixing bowl.
• Pour in your preferred spaghetti sauce – whether it’s a rich marinara, a hearty bolognese, or a zesty pesto.
• Stir in a generous amount of grated Parmesan cheese and a few of your go-to Italian spices, such as oregano, basil, or garlic powder, just as you would with regular spaghetti.
• For a truly impressive presentation, spoon this flavorful mixture back into the emptied squash halves, creating natural “squash bowls.”
• Top everything with an extra layer of your favorite melting cheese, like mozzarella, provolone, or a blend of Italian cheeses.
• Place the filled squash halves onto a rimmed baking sheet.
• Bake in a preheated oven at 375 degrees F for about 10-15 minutes, or until the cheese is beautifully melted and golden brown. A sprinkle of fresh green onions or parsley adds a lovely finish.
• Finally, a dash of salt and pepper to taste, and you have a dish that’s absolutely irresistible!

No matter how you decide to prepare it, the tender, flavorful insides are truly amazing. Even my kids, who usually detect any deviation from their usual meals, were pleasantly surprised. They noted it was “pretty good” and were astounded to learn they were eating vegetables instead of starch. They even asked me to make it again soon, which is the highest culinary compliment a parent can receive!

How to Cook Spaghetti Squash in the Oven: The Traditional Method

For those who prefer a more traditional approach or don’t own a pressure cooker, baking spaghetti squash in the oven is a classic and reliable method. While it takes significantly longer than pressure cooking, it still yields delicious results, often with slightly caramelized edges. Bear in mind that this method will heat up your kitchen, which might be less ideal during warm summer months.

1. Prepare the Squash: Begin by cutting the spaghetti squash in half lengthwise and scooping out all the seeds and stringy pulp from the center.
2. Preheat Oven: Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius).
3. Season and Bake: Place the squash halves cut-side up on a baking sheet. You can rub a little olive oil or butter along the edges of the cut sides to help prevent them from drying out and ensure they stay moist and tender. Season with salt and pepper, if desired.
4. Bake Until Tender: Bake for 30 to 45 minutes, or until the flesh is tender enough to be easily scraped into strands with a fork.
   1. The exact cooking time will vary depending on the size of your squash. Larger squash will naturally require a longer baking period. Check for tenderness after 30 minutes and continue baking in 5-10 minute increments as needed.
5. Cool and Serve: Once tender, remove the squash from the oven, let it cool slightly, and then scrape out the “noodles” to serve as desired.

Expert Tip: How to Soften Spaghetti Squash for Easier Cutting

Spaghetti squash can be notoriously hard to cut when raw, posing a challenge even for the sharpest knives. Your best bet for making the cutting process safer and easier is to pre-soften the squash using your microwave. This simple trick not only reduces the effort required to slice it open but can also slightly decrease the overall cooking time, regardless of the method you choose next.

How to Cook Spaghetti Squash in the Microwave

The microwave is an excellent tool for quick and easy vegetable preparation, and spaghetti squash is no exception. We often share easy microwave recipes on our site because they’re incredibly simple and fast. Cooking spaghetti squash in the microwave is quite similar to how to cook acorn squash in the microwave, with the main difference being that spaghetti squash is typically larger and may require a few more minutes of cooking time.

• Prepare the Squash: Carefully cut the spaghetti squash in half lengthwise and thoroughly remove all the seeds and stringy pulp.
• Arrange in Dish: Place the squash halves cut-side down in a microwave-safe dish.
• Add Water: Pour 1 to 2 tablespoons of water into the dish around the squash. This helps create steam, ensuring even cooking and tenderness.
• Microwave: Cover the dish (with a microwave-safe lid or plastic wrap, venting slightly) and microwave on high for 9 to 12 minutes.
• Check for Doneness: After 9 minutes, check for tenderness by piercing the flesh with a fork. If it’s not tender enough, continue microwaving in 1-minute increments until it reaches your desired consistency.

Once cooked, you can scrape out the tender strands as described earlier. For an even softer texture suitable for blending, microwave for a few extra minutes. These softer strands can be added to recipes like creamy butternut squash soup, enhancing flavor, texture, and nutritional value. Mixing different squash varieties can also introduce a range of essential vitamins and minerals to your dish.

Spaghetti Squash in Ninja Foodi: Pressure Cook & Air Crisp

The Ninja Foodi is another fantastic multi-cooker that functions much like an Instant Pot for pressure cooking, offering the same swift results for spaghetti squash. Its main advantage lies in its air frying capability, which opens up exciting possibilities for finishing your dish. While not strictly necessary for cooking the squash, the air crisp function is perfect for melting cheese or adding a delightful crispy texture, especially if you’re making a twice-stuffed spaghetti squash.

• Pressure Cooking Phase: Follow the same Instant Pot directions detailed above for pressure cooking. Use the trivet and the pressure cooker lid of your Ninja Foodi. This ensures the squash cooks quickly and becomes perfectly tender.
• Air Frying for Stuffed Squash: If you’re creating stuffed spaghetti squash with sauce and cheese, you can bypass the oven and use the air crisp lid to melt and brown the cheese!

This dual functionality makes the Ninja Foodi a favored method in our kitchen, especially when we want to add that perfect golden crust to our cheese toppings.

• When using the air fryer lid for melting cheese, you’ll need to work with one squash half at a time to ensure even cooking and browning across the entire cheese-filled top.
• Place a filled squash half on the trivet, close the air fryer lid, and set it to 400 degrees Fahrenheit for approximately 5-6 minutes. Keep an eye on it until the cheese is beautifully melted and golden brown.
• Many Instant Pot models now also offer an air fryer lid accessory. If you have this, you can achieve the same crisping results without needing a separate Ninja Foodi appliance.

Storing and Reheating Cooked Spaghetti Squash

Don’t let any delicious leftovers go to waste! Cooked spaghetti squash stores remarkably well. If you have any halves left, it’s best to keep them intact. The robust outer shell acts as a natural bowl, helping to keep the squash moist and fresh in the refrigerator. To maximize freshness, place the squash halves in a gallon-sized freezer bag, pressing out as much excess air as possible before sealing. Stored this way, cooked spaghetti squash will remain fresh for up to 3-4 days in the fridge.

When you’re ready to enjoy your leftovers, reheating is a breeze. You can place the squash halves back on a trivet in your pressure cooker with a bit of water at the bottom and use the sauté function to steam until warm. Alternatively, for a quicker option, simply microwave the squash for about 1 minute, checking and adding more time if needed. Proper storage and reheating mean you can savor this healthy and delicious vegetable for days, ensuring nothing is wasted.
