Plant-Based Broccoli Parmesan Spaghetti Squash

Plant-Based Broccoli Parmesan Spaghetti Squash combines spaghetti squash with roasted broccoli and mushrooms. Topped with a salty, cheesy vegan parmesan!

Plant-Based Broccoli Parmesan Spaghetti Squash

Normally I start my posts with a little anecdote about the food. Or a story about how the recipe came together. Sometimes I rant about something or talk about how to eat healthier.


Today we're diving straight into this dish because I am dying to tell you about this vegan parmesan.

Guys, this parmesan is legit! It is cheesy and salty and slightly crunchy, but not too much because it's supposed to be like cheese.

I seriously want to sprinkle this stuff on everything I eat from now on. It has all the flavor and texture you could want.

I may or may be eating this by the spoonful. It's THAT good.

And it's so incredible because it's completely plant-based. It's actually good for you.

It's simple to make too. Just throw the ingredients in the food processor and pulse for a few minutes until everything is broken up and incorporated. Then sprinkle it on EVERYTHING.

But I'm getting ahead of myself. I am in love with this parm, but I don't want it to completely overshadow the dish I'm serving it on. Because the spaghetti squash deserves some attention too.

As per usual, this recipe is nothing complicated. There's actually only a few ingredients: spaghetti squash, broccoli, mushrooms, and vegan parmesan.

How to make Plant-Based Broccoli Parmesan Spaghetti Squash

Start by cutting the ends off of your spaghetti squash. Then cut it in half lengthwise. Scoop out the seeds and lay it face down on a baking sheet lined with aluminum foil. Bake at 400 for 40 minutes.

If you want more detailed instructions, check out my post on how to cook spaghetti squash.

After you get the spaghetti squash in the oven, prep the broccoli and mushrooms. Chop up a head of broccoli and slice your mushrooms (if you don't buy them pre-sliced). Place them on another foil-lined baking sheet.

Sprinkle some water or veggie broth over the veggies so they don't stick. Then bake them with the spaghetti squash for 15 minutes.

While all the vegetables are in the oven, make the vegan parmesan.

Vegan Parmesan Ingredients

This vegan parm is SO simple and SO delicious. All you need is a few ingredients and a food processor. In 5 minutes you'll have a jar full of deliciousness!

  • Cashews: Cashews are the base of the parm. They provide a nuttiness and slight sweetness. But mostly, they provide texture! When you grind them up just enough, they take on a similar texture to parmesan.
  • Nutritional Yeast: Known for its cheesy flavor, nutritional yeast is the star of the show in this parm. As the name suggests, nutritional yeast has tons of vitamins and minerals. But honestly, it's really about the cheese flavor!
  • Garlic Powder: Garlic adds just a hint of spice, without actually adding any spice.
  • Salt: I know many people are watching their salt intake, but this recipe needs to be one of the exceptions. Salt does an amazing job of bringing out the flavors of all the other ingredients, especially the nutritional yeast.

To make the parm, add all the ingredients to a food processor and pulse until the cashews are broken up into tiny chunks. It will resemble actual parmesan.

Assembling Plant-Based Broccoli Parmesan Spaghetti Squash

When the spaghetti squash, broccoli, and mushrooms are cooked, you're ready to assemble the dish.

Use a fork to scrape the spaghetti squash out of the shell. Then mix the broccoli and mushrooms in with the squash.

Sprinkle with ALL the vegan parmesan that you heart desires (hopefully a lot!). And enjoy!

Thank you God for delicious flavors and healthy meals. Amen.

  • 1 Medium Spaghetti Squash
  • 8 Ounces Sliced Mushrooms
  • 2 Heads Broccoli
  • 1/4 Cup Cashews

  • 1 Teaspoon Garlic Powder
  • 1/4 Teaspoon Salt

  3. Chop the broccoli. Place the broccoli and mushrooms on the other baking sheet. Sprinkle with salt and pepper. Add a tablespoon or two of water, so the veggies don't stick. Bake with the spaghetti squash for 15 minutes.
  4. While the veggies are in the oven, add the cashews, nutritional yeast, garlic powder, and salt to a food processor. Pulse until the cashews are in small pieces, resembling parmesan.

Elizabeth: Thank you so much for making my meal times wonderful again. I am 86 yrs plus, and was finding eating dull and dreary. Now it is " scrum delicious time to eat". . Blessings de Jean
Hi Jean - Thanks so much for your kind words. I'm so glad you are enjoying my recipes. Please let me know if you ever have recipe requests or if there's anything else I can do to keep your meals delicious!

Can you leave nutritional info for your recipes? Serving size/calories would be so helpful! Trying mushroom lentil stew tonight! and looking forward to crispy chickpea stuffed sweet potatoes very soon. Thanks for creating healthy, attractive recipes!
Hi Katie - so excited to hear that you are trying some of my recipes! I'd love to hear how they go. I haven't posted nutritional information for my recipes because I know it can be difficult for some people with disordered eating to see nutrition facts. I've gotten a lot of requests to add them recently, so I'm working on a solution that can provide information for those who want it but not be triggering for others. In the meantime, if you're curious about the nutrient info about a particular recipe, I recommend using Cronometer. It's a website/app to track and understand nutrient info and I think it does a great job of emphasizing all the nutrients (not just macros). I hope this helps! Please let me know if I can help in any other way.

I'd love to try this soup. What are the nutritional values, like how much fat does it contain, carbs, etc.
Hi Sr Maureen - I usually don't post macronutrient information because I know each person has their own goals and I don't want to encourage or discourage anyone's specific goals. But I often use Cronometer as a tool to understand the nutritional profile of my recipes. I plugged the ingredient information for this recipe into Cronometer and got the following nutrient information per serving: 521 calories, 44g fat, 23g carbs, 16g protein. I hope this helps. Please let me know if you have any other questions and if you try the recipe!

Thank you I have been doing the fruit and oatmeal, etc for years and I love it. I will try the pears. I refrigerate my left over oatmeal and with a touch of milk or fruit juice liquid it’s fine the next day. Just a warning about tofu; it interferes with some medicines especially Thyroid medicine. Thank you for the short prayers, there are lovely.
Hi Martha - thank you so much for your kind words. I'm glad you like the prayers! As someone who doesn't take any medications I have no issues with eating tofu and encouraging others to eat it too (it's a great source of protein!). That said, you should always consult with your doctor about possible interactions with medications. I have plenty of recipes without tofu, so hopefully you can find things that work for you!

I made this for Ash Wednesday and it was delicious. It was also simple and not much work time once the mushrooms and onions were cut.
Hi Susan - I'm so glad you liked it!

When you say shape into a rectangular loaf, what dimensions? 1/2 thick by 8 inches long or?
My loaf was about 7" long and 4" wide with about 1" of height. Then I sliced it 1/2" thick along the long end to get 12ish biscotti. I will clarify this in the post! Let me know if this makes sense and if you have any other questions.

Hi Could you please confirm two things:1. The amount of salt. Seems like too much. 2. The directions say there is lemon juice in the dressing but it’s not listed under ingredients. ThanksL.
Hi there! Confirming that the two teaspoons of salt in the dressing is correct. I didn't salt the cauliflower when roasting it or the salad after it was done, so this amount of salt was perfect. If you're concerned about it you can decrease the amount of salt in the dressing and then add more at the end if you need it. As for the lemon juice, SO sorry about that! It was a typo in my directions and I've removed it now. Hope this helps :)

This looks lovely! Do you have a recipe for the red pepper hummus also? Thank you!
Hi Martha! I don't have a recipe for red pepper hummus on my site. I suggest taking a traditional hummus recipe and blending in roasted red pepper.

I tried these and they were delicious! A bit dense but flavorful and the "buckeye" blend of peanut and chocolate was on point! Recommend!
Yay! I'm so glad you liked them! -- Elizabeth

Hi, these look amazing. I was wondering, could I used powdered peanut butter in place of creamy for the recipe? thanks
Hi Grace! There is already some powdered peanut butter in this recipe, so adding more might make the texture more gluey. Also, the real peanut butter adds some fat, which helps create flavor. That said, if you want to use powdered peanut butter, I would suggest mixing it with a high-fat liquid like coconut cream and then measuring out 2/3 cup. Hope this helps! Let me know how it goes :) -- Elizabeth

You mention using vegetable broth in your introduction but it isn’t included in the recipe
Hi Becky - thanks for pointing this out. I have removed mention of vegetable broth from this post. You do not need any vegetable broth. The mushrooms will release natural liquid which will prevent any sticking. -- Elizabeth

Hi Elizabeth, LOVE you recipes. Please keep them coming. :)I was wondering, can you share what is the vegan chocolate bar you used in this recipe?

thank you for the oil free recipe. I'm getting introduced to wild Bolete mushrooms here in Colorado, and everyone sautes Bolete's in butter or olive oil. I'm on a veggie, oil free regimen for heart health reasons. and your recipe suggestion may fill the bill. I can't wait to give it a try.
