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.

I was in the middle of making your Tempeh Swiss Chard recipe and noticed you never mentioned how much Swiss Chard to add. I just added the sautéed tempeh towards the end and mixed it all together. I also reduced the amount of red pepper flakes.
Hi Jenny - so sorry about that! It should be one bunch. I've updated the recipe to include the correct information. Thanks!

This looks fantastic! Do you think we could substitute butternut squash for the acorn squash?
Hi Elissa - you can definitely use butternut squash. In terms of texture, the pie will be exactly the same with either squash. I'd recommend using the volume measurement instead of the weight measurement, since the density of butternut squash isn't exactly the same as acorn squash. Also, the flavor of the butternut squash might come through in the end pie a bit more prominently than acorn squash does, but I don't think it will be too noticeable. Let me know how it goes if you try with the butternut squash. I'd love to hear!

THIS LOOKS DELICIOUS! DID YOU USE FIRE-ROASTED TOMATOES?
Hi Katherine - yes, I did use fire-roasted tomatoes when I photographed this recipe. I don't call for fire roasted in the recipe because it's intended to be a basic, use-in-anything type recipe. But it does taste delicious with the fire roasted tomatoes! -- Elizabeth

As someone who has pretty much never successfully scrambled tofu - this was the best scrambled breakfast dish I've ever had - better than eggs and the seasoning is truly delicious!!

It's close to my bedtime, but I've been thinking about making this recipe all day, so I made it just now. After all, it only takes 15 minutes! I used what I had, so I made a few minor substitutions...white beans for cannellini, purple basil from my garden, red onion for more color, and date syrup for maple. I took a bite before putting it in the fridge for tomorrow, and oh my! It's delightfully flavorful, light, and fresh-tasting. Thanks for sharing your recipe!
Hi Linda - I'm so glad you liked the recipe - and your substitutions sound great (wish I was growing purple basil in my garden!) Thanks so much for sharing!

Hi, is this ice cream soft to scoop out? I always find my ice creams are hard.
Hi Carol - yes, this ice cream is soft if you let it thaw a few minutes after you take it out from the freezer. It can become pretty solid if it's in a deep freezer, but still thaws quickly on the counter. Hope this helps!

Hi Elizabeth! I found you by searching for plant based Catholics! There are very few of us! Thank you for your site and sharing recipes!! I look forward to trying these muffins! Can sugar be reduced safely in most of your recipes? -JMJ-
Hi Katherine, Thanks so much for reaching out! Glad to meet another plant-based Catholic - agree, there are so few of us. As for sugar, I never use white granulated sugar in any of my recipes. Most use maple syrup or date sugar/date syrup. I'm not sure if this is what you mean, or if you're asking about reducing the amount of date sugar that the recipe calls for. If that's the case, it really depends on the recipe. A lot of the baking recipes have specific ratios of flour to sugar and wet to dry, so it may not go well if you change the amount of sugar. I hope this helps, but if I didn't answer your question, please let me know. Also happy to advise on a particular recipe if you're looking to change it. Let me know how I can help :) Elizabeth

Hello, I found you on FB and really enjoy your Catholic Plant Based GF information & recipes. About the Chickpea beet burgers: if the beans are dried and not cooked, do you think it is enough cooking for the beans? If beans are not cooked completely I have read they are toxic with phytic acid & also cause digestive problems. I am just wondering and will leave it to you to decide/research. To be safe I am toasting canned garbanzos and trying that way out. God Bless
Hi Geraldine, Thanks so much for reaching out. In the beet burgers, the beans do get cooked when the burgers are cooked. You soak them first and then incorporate the beans into the burger patty, then cook the patty. I find that this is the best way to achieve the proper burger texture - if you use pre-cooked beans or canned beans the burgers are mushy and don't get crisp. Your solution of toasting the beans sounds like a great idea to completely ensure the beans are cooked fully - I hope that it worked for you and your burgers turned out well! -- Elizabeth

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!

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 :)

Grace
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

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.
