    If you're looking to load up on veggies, this dish is for you.

    Spaghetti squash is such a great summer veg - it feels like you're eating spaghetti but it's actually a vegetable! And one spaghetti squash makes so much food, you'll have tons of leftovers!

    The spaghetti squash in this dish gets tossed with roasted mushrooms and broccoli for even more veggies.

    And the entire dish is sprinkled with vegan parmesan.

    If you haven't tried my vegan parm, you are in for a treat! I can only rave about this parmesan. It's cheesy and salty and addicting! It turns a boring veggie recipe into a flavorful, exciting dish!

    Why I love this Spaghetti Squash with Roasted Mushrooms

    • Dietary needs - this dish is vegan, gluten-free, dairy-free, oil-free, and sugar free. Great for all diets!
    • Veggie loaded - spaghetti squash, mushrooms, and broccoli. This dish is all veg.
    • Only uses the oven - you'll cook both the spaghetti squash and the mushrooms & broccoli in the oven.
    • Really Easy - while the veggies are in the oven, grab just four ingredients and whip up the vegan parm in only 5 minutes
    • Tastes cheesy & salty & umami - the vegan parmesan seriously makes the dish!

    Ingredient Notes & Substitutions

    • Spaghetti Squash: Spaghetti squash is a fun type of squash named because the tender part of the squash looks like spaghetti. They are in season late summer and early fall, so buy them when they're fresh!
    • Mushrooms: I used cremini mushrooms (also known as baby bellas) because they have more flavor. White button mushrooms work just fine too!
    • Broccoli: I like to buy the broccoli crowns to maximize the ratio of florets to stems, but you can and should eat the entire stalk of broccoli, including the stems - just cut off the tough exterior
    • Salt & Pepper
    • Vegan Parmesan: head over to this post for notes and full instructions.
