Make this Instant Pot Stuffed Spaghetti Squash next time you’re looking for a vegetarian meal prep idea that you can enjoy all week long! It’s ready in 30-minutes!

Vegetarian Meals Made Easy

You don’t need meat to have a balanced meal. We have so many delicious vegetarian recipes on Fit Foodie Finds that are great for a quick healthy dinner idea or even for meal prep throughout the week. I understand that sometimes it can be hard to make a vegetable a main dish, but it can be fun to take a vegetable you usually use as a side dish and turn it into the main meal! Squash is a hearty vegetable that is very versatile and compliments flavors just like any other protein or pasta. Our Instant Pot Butternut Squash can be a delicious addition to any vegetarian salad! Spaghetti squash is a whole other ball game, but no doubt makes a delicious alternative to PASTA. Yes, I said it. PASTA. Let’s get started.

How to Make Instant Pot Spaghetti Squash

If there is one thing I absolutely love about the Instant Pot, it’s that it cooks things that usually take hours, in minutes! Our Instant Pot Pork Roast and Instant Pot Butternut Squash are two Fit Foodie Favorites that we turned into meals and they take no time at all! This Stuffed Instant Pot Spaghetti Squash is going to be your new favorite meal prep lunch recipe.

Step 1: Gut the Squash

Step one is to prep the squash to be cooked in the Instant Pot. The key to cutting the squash is to have a good, sharp knife! Also, make sure you have a solid and steady cutting board. Next, carefully cut off the stem of the squash so that you have a flat surface. Flip the squash on its flattest end and cut the squash lengthwise (hotdog style). Use a spoon to scoop out the seeds and slimy innards and discard them. Now your squash is ready!

Step 2: Sauté the Veggies

There are two different times during this recipe where you will have to use the sauté feature. The first time you sauté the onions, garlic, and mushrooms. You sauté these vegetables first to cook down the mushrooms and to make a delicious base for the sauce that you will eventually mix with your spaghetti squash. The mushrooms create moisture that works with the broth to steam the spaghetti squash until perfectly cooked. After sautéing the first round of vegetables, place the trivet on top of the vegetables and then place the seasoning spaghetti squash on top of the trivet and cook on high for 6 minutes. Why do I need a trivet? If you are planning on using the squash skins as the “bowls” to serve this stuffed spaghetti squash in, you don’t want the squash skins to get to mushy. Keeping them from cooking in the moisture of the mushrooms will help the skin keep its integrity.

Step 3: Shred Spaghetti Squash

After the cook time is up, carefully remove the spaghetti squash from the Instant Pot as well as the trivet. When the spaghetti squash has cooled a bit, take two forks and gently shred the squash into noodle-like pieces (similar to how you shred chicken). Be extra gentle and try not to mash the squash and try to keep the integrity of the squash skins (you’ll be using them as bowls after the recipe is done). You are going to prepare this spaghetti squash as you would prepare noodles and sauce.

Step 4: Sauté Again + Make the Sauce

Finally, you turn the sauté feature on again and you add the kale, sun-dried tomatoes, tomato paste to the Instant Pot. Sauté everything together until the kale softens. Why add tomato paste? The tomato paste thickens the broth when heated. It helps to make a flavorful sauce that will cover all the vegetables and spaghetti squash. YUM.

Step 5: Mix it All Together

After all of the vegetables are sautéd and there is a thicker sauce at the bottom of the Instant Pot, its time to add the spaghetti squash to the Instant Pot. Slowly fold the spaghetti squash with all of the other ingredients until the spaghetti squash is covered in the tomato sauce. After everything is mixed together, serve the spaghetti squash in the hollowed-out spaghetti squash skins as bowls or any bowl of your choice. Top with optional toasted pine nuts and parmesan.
