Prep the spaghetti squash by washing the outside, drying it with a paper towel, and then cutting it in half lengthwise. Remove the seeds.
Add 1 cup of water to the bottom of the pressure cooker and insert the steamer rack trivet.
Place the spaghetti squash halves on top of the instant pot trivet with the squash facing down. They won't both fit perfectly and we needed to place one spaghetti squash half on its side to fit.
Pressure cook the spaghetti squash on high for 7 minutes, and then do a Quick Release of the remaining pressure.
Remove lid, squash, and trivet from the pot. Drain any moisture that collected inside the squash. Discard the water in the pot and remove the trivet.
Use a fork to shred the instant pot spaghetti squash into long strands and then serve with butter (or olive oil), salt and pepper or try it with our garlic parm sauce. Serve the pressure cooker spaghetti squash in either a bowl or in the squash shell.
Garlic Parmesan Sauce
Over medium heat, melt the butter in the pot. Add the garlic and stir for 1 minute until fragrant. Add the salt, pepper, and chicken broth and combine.
In a small bowl combine the spaghetti squash, garlic broth mixture and the parmesan cheese.
Toss with two forks to combine.
Garnish with fresh parmesan cheese and the fresh parsley.

Notes
Skip all the sauces if you just need a basic spaghetti squash pressure cooker recipe.
Serve with alfredo sauce, marinara sauce, garlic parm sauce, or just with butter, salt and pepper.
Cutting the squash in half lengthwise will give you short spaghetti squash strands, if you cut it in half across the width, it'll give you longer strands.
To cook the squash al dente reduce the cook time to 4-5 minutes.
To cook the spaghetti squash whole, put the entire squash in the pressure cooker for 10 minutes and do a Natural Release. Remove the seeds after it's cooked with a cookie scoop or ice cream scoop.
