Embrace Effortless Vegetarian Meals
Eating a balanced, satisfying meal doesn’t always require meat. In fact, vegetarian cooking opens up a world of vibrant flavors and diverse textures, proving that plant-based dishes can be incredibly fulfilling and packed with nutrients. At Fit Foodie Finds, we believe in making healthy eating accessible and enjoyable, offering a plethora of vegetarian recipes that are ideal for everything from a quick healthy dinner idea to an entire week’s worth of meal prep.
It’s a common misconception that vegetables are best relegated to side dishes. However, with a little creativity, you can easily transform your favorite veggies into the star of the show. Spaghetti squash, in particular, is a game-changer. Its unique stringy texture, which mimics pasta noodles, makes it an excellent, low-carb alternative to traditional spaghetti. This versatile gourd readily absorbs the flavors of accompanying ingredients, making it a fantastic base for a variety of savory fillings, just like any protein or grain. While our Instant Pot Butternut Squash adds a creamy, sweet touch to salads and soups, spaghetti squash is truly in a league of its own when it comes to replicating the comforting experience of a pasta dish. Get ready to elevate your plant-based cooking and dive into this exciting recipe!
Mastering Instant Pot Stuffed Spaghetti Squash
The Instant Pot is a true culinary marvel, celebrated for its ability to dramatically cut down cooking times for dishes that traditionally take hours. This makes it an indispensable tool for healthy cooking, especially for busy individuals and families. Forget waiting an hour or more for your spaghetti squash to roast in the oven; the Instant Pot delivers perfectly cooked, tender strands in a fraction of the time. This efficiency is why beloved recipes like our Instant Pot Pork Roast and Instant Pot Butternut Squash have become Fit Foodie favorites. This Stuffed Instant Pot Spaghetti Squash is poised to become your new go-to recipe for a satisfying and healthy meal prep lunch or dinner. Let’s break down the simple steps to create this incredible dish.
Step 1: Preparing Your Spaghetti Squash
The first crucial step to creating perfect Instant Pot Stuffed Spaghetti Squash is preparing the squash itself. A clean, safe cut is essential. Always ensure you have a high-quality, sharp chef’s knife and a stable, non-slip cutting board before you begin. Safety first in the kitchen!
Carefully trim off both ends of the spaghetti squash to create flat, stable surfaces. This will prevent the squash from rolling as you cut it. Once the ends are removed, stand the squash upright on its flattest end and, using your sharp knife, carefully slice it lengthwise down the middle. This “hotdog style” cut is ideal for creating two boat-like halves. Next, grab a sturdy spoon and scoop out all the seeds and fibrous, slimy innards from both halves. Discard these, and your squash is now perfectly prepped and ready for its Instant Pot transformation!
Step 2: Sautéing the Flavorful Veggie Base
The Instant Pot isn’t just for pressure cooking; its sauté function is incredibly useful for building deep layers of flavor. In this recipe, you’ll be using the sauté feature at two distinct stages. The first stage involves creating a aromatic foundation by sautéing onions, garlic, and mushrooms directly in the Instant Pot.
Begin by heating your olive oil in the Instant Pot on sauté mode. Once shimmering, add the minced onions and cook until they become translucent and fragrant. Then, introduce the minced garlic and chopped crimini mushrooms. Sautéing the mushrooms first allows them to release their moisture and develop a rich, earthy depth of flavor, which is crucial for a robust sauce. This initial sauté also creates a delicious liquid base when combined with the broth, essential for perfectly steaming the spaghetti squash later.
After this initial sauté, turn off the sauté function and place the trivet (the metal rack that often comes with your Instant Pot) directly on top of the sautéed vegetables. Gently place the seasoned spaghetti squash halves onto the trivet. This separation is key for two reasons:
Why use a trivet? The trivet elevates the squash halves above the liquid and other vegetables. This ensures the squash steams evenly without becoming waterlogged or mushy. Crucially, if you plan to use the squash skins as natural “bowls” for serving (which we highly recommend for a fun presentation!), keeping them from sitting directly in the liquid helps them maintain their structural integrity throughout the cooking process. Now, seal the Instant Pot and cook on high pressure for 6 minutes, followed by a quick release.
Step 3: Unveiling the “Squash Noodles”
Once the pressure cooking cycle is complete and you’ve performed a quick release, carefully open the Instant Pot and remove the cooked spaghetti squash halves, along with the trivet. Allow the squash to cool for a few minutes until it’s comfortable enough to handle.
Now comes the magical part: transforming the cooked squash into delicate, pasta-like strands. Take two forks and gently scrape the flesh from the inside of each squash half. Work from the outside edges towards the center, shredding the squash into beautiful, noodle-like pieces. The goal is to create distinct strands, similar to how you would shred chicken, rather than mashing it. Be gentle to preserve the integrity of these “squash noodles.” As mentioned earlier, if you intend to serve the finished dish in the squash skins, be mindful not to damage them during this process. These hollowed-out halves will make charming and practical serving bowls!
Step 4: Crafting the Rich Sauce and Finishing the Sauté
With your spaghetti squash noodles ready, it’s time for the second sauté phase to bring the filling together. Return the Instant Pot to sauté mode. Add fresh kale, sun-dried tomatoes (which add a burst of concentrated tomato flavor and a chewy texture), and a crucial ingredient: tomato paste. Sauté these ingredients with the existing vegetable base until the kale wilts down and turns a vibrant, softened green.
Why is tomato paste important? Tomato paste is a secret weapon in many savory recipes. When heated, it caramelizes slightly and helps to thicken the broth, creating a luscious, deeply flavored sauce that will cling beautifully to every strand of spaghetti squash and every piece of vegetable. This concentrated tomato essence enhances the overall savory profile, transforming the simple broth into a robust, hearty sauce. The combination of kale, sun-dried tomatoes, and a rich tomato-infused base makes for an incredibly flavorful and visually appealing stuffing.
Step 5: Bringing It All Together for a Flavorful Finish
Once your vegetables are perfectly sautéed and the rich, thickened sauce has formed at the bottom of the Instant Pot, it’s time for the grand finale: combining all the elements. Carefully add the shredded spaghetti squash noodles into the Instant Pot with the saucy vegetable mixture.
Using a large spoon or spatula, gently fold the spaghetti squash with all the other ingredients. The goal is to thoroughly coat every strand of squash and every vegetable piece with the delicious tomato sauce. Take your time to ensure an even distribution of flavor and texture. This step integrates the mild, subtly sweet squash with the savory, tangy, and earthy flavors of the sautéed vegetables and rich sauce.
Once everything is beautifully mixed, you can serve this incredible stuffed spaghetti squash in the hollowed-out squash skins – a delightful and eco-friendly way to present your meal. Alternatively, serve it in any bowl of your choice. For an extra layer of texture and nutty flavor, top your servings with a sprinkle of optional toasted pine nuts and a generous shaving of fresh Parmesan cheese (or a dairy-free alternative for a vegan option). This final touch adds a gourmet flourish to your homemade vegetarian masterpiece.
Simplified Meal Prepping for the Week Ahead
One of the greatest advantages of this Instant Pot Stuffed Spaghetti Squash recipe is its incredible suitability for meal prepping. Imagine having a healthy, satisfying lunch or dinner ready to go for several days, saving you time and stress during busy weekdays.
To transform this into a perfect meal prep lunch or dinner, simply scoop the delicious stuffed spaghetti squash out of its skin and portion it into four individual airtight meal prep containers. Allow the squash to cool completely before covering the containers and storing them in the refrigerator. Properly stored, this dish will stay fresh and delicious for up to 5 days, making it an ideal choice for healthy grab-and-go meals throughout your week.
When you’re ready to enjoy your prepped meal, reheating is a breeze. For quick convenience, simply remove the lid from the meal prep container and warm the stuffed squash in the microwave until it reaches your desired temperature. If you prefer a slightly crispier texture or don’t use a microwave, you can transfer the stuffed squash to a skillet pan and cook it over medium-high heat on the stovetop, stirring occasionally, until it’s heated through and develops a pleasant sizzle. Enjoy the ease and deliciousness of homemade meals, even when time is tight!

Ingredients
- 1 2-lb. spaghetti squash
- 1 tablespoon olive oil
- 1/2 medium white onion, minced
- 3 cloves garlic, peeled and minced
- 8 oz. crimini mushrooms, chopped
- 1/4 teaspoon salt
- 1/4 teaspoon ground pepper
- 1/2 cup vegetable broth, but any kind works!
- 4 cups chopped kale, deboned
- 1/2 cup julienned sun-dried tomatoes, in oil
- 1 tablespoon tomato paste
- 1/4 cup shaved parmesan
- Optional: 1/4 cup toasted pine nuts
Instructions
-
First, prepare the spaghetti squash by cutting off the stem end of the squash with a sharp knife. Set the spaghetti squash flat on a cutting board and carefully cut the squash in half (hot dog style).
-
Use a spoon to scoop out the seeds and then discard the seeds. Lightly season squash halves with salt and pepper. Set aside.
-
Next, turn the Instant Pot’s saute feature on and add 1 tablespoon olive oil to the bottom of the pot.
-
When the olive oil is fragrant, add onion to the pot and saute for 1 minute. Then, add garlic, chopped mushrooms, 1/4 teaspoon salt, and 1/4 teaspoon pepper and cook for an additional 2 minutes.
-
Next, pour broth into the bottom of the pot and set the trivet on top of all of the vegetables.
-
Place spaghetti squash halves on top of the trivet and cover the Instant Pot.
-
Turn the pressure valve to seal and set the Instant Pot to manual >> high pressure for 6 minutes.
-
It will take a few minutes for the Instant Pot to build pressure, but eventually it will count down from 6 minutes. When the timer goes off, quick release the Instant Pot.
-
Then, carefully remove the squash and trivet from the Instant Pot and set aside.
-
Turn the saute feature back on and add chopped kale, sun-dried tomatoes, and tomato paste to the pot. Saute everything together for 2-3 minutes or until the kale becomes softer and bright green.
-
While the veggies are sauteeing, carefully scoop out the innards of the spaghetti squash. We like to use a fork to fluff the “squash noodles” and then scoop everything out. If you are serving this dish immediately, make sure to keep the squash skin intact so that you can serve it inside the squash half.
-
Spoon the squash innards into the Instant Pot and saute everything together.
-
Last, add parmesan cheese and mix again.
-
Serve with toasted pine nuts and enjoy!
