Once I learned –> the trick <– to getting long, actual spaghetti-like strands from spaghetti squash, I'm always on the look out for new ways to eat it.

We've made it a few ways here on the site so far:

And there's always the option to just substitute it in your favorite spaghetti pasta dish for a little less carbs and a little more veggies. Which I haven't really written about – until now!

If you're someone who isn't a fan of red sauce and just like a little olive oil and flavor, this is the dinner dish for you.

I particularly like the crunch factor from the red onion slices, and the flavor from the herbs and salt and pepper is KEY. Basil and parsley are my favorites to add, and oregano would be a good option as well!

Options to add more flavor: sauté the mushrooms with minced garlic or add chili pepper flakes.

You can eat it in the half-shell (though remember this is the opposite of the trick to get long strands)…

Prep Time 45 minutes
Cook Time 5 minutes

Instructions

  1. Bake and cut your spaghetti squash according to preference. (See this linked post for options and instructions.)
  2. In a medium skillet, heat 1 tablespoon olive oil over medium-high heat. Once hot, add sliced mushrooms and stir-fry until tender, about 3 minutes.

  4. Top with herbs, salt and pepper and serve!

Notes

  • Options to add more flavor: sauté the mushrooms with minced garlic or add chili pepper flakes. Or see how to make caramelized mushrooms.

Kelly, Your photograph of the spaghetti squash and mushroom dish really caught my eye, and I’m looking forward to making it, after my surgery recovery and I get back into cooking. I also really liked and appreciated your explanation and description of how to easily soften the shell and ‘how to’ end up with long spaghetti -like strands of squash. Taking the time, as you have, to explain this, adds to the appearance of the dish!
