Hands down, this is the BEST spaghetti squash dish.

Spaghetti Squash Aglio E Olio with Rainbow Chard | @hbharvest

I will admit, I pretty much love spaghetti squash in every which way it can be served it up. It’s one of my favorite veggies, and about the only veggie I can truly eat in place of a carb like pasta. I know that my cousin Abby actually prefers spaghetti squash over real spaghetti. I’m not sure I can go that far, because well, real pasta will always be the best, but spaghetti squash is high on my list of favorite foods!

Why is THIS recipe the best though? Because it’s SO simple, SO easy, super healthy, and yet SO freaking good.

AND it’s got a grand total of SEVEN ingredients. Yes, please! Just spaghetti squash, olive oil, garlic, crushed red pepper flakes, swiss chard, parmesan, salt and pepper. Like the most basic ingredients, but I promise, it’s the best. It’s Italian made super healthy…and who wouldn’t be totally down with that.

So you guys! Aside from the pasta, I also have to tell you some random things. Random Gilmore Girls things. I finally finished the new Gilmore Girls, a Year in a Life. It only took from Thanksgiving until now for me to finish, but you have to understand, I practically watch ZERO TV, so really it’s a miracle I ever finished. I somehow even managed to not let the internet spoil the outcome, which was probably one of the hardest things ever since it was EVERYWHERE.

Anyway, I watched all four seasons, and guys, I dunno. I don’t want to spoil it for anyone who has yet to watch, but I’m not sure about the ending. I mean, don’t get me wrong I LOVED every minute of it and want to watch it over and over (read: need more time), but the ending threw me a bit. The good news is that the ending left A LOT to be told, meaning more episodes are a must. I mean, right? Hoping someone high up at Netflix is possibly reading because I SO want more episodes.

You guys are with me, right?

Also, do you think Lorelai and Rory would partake in “Healthy January” I’m kind of thinking it’s just not in them. What would life without doughnuts, pop-tarts, pizza, and burgers be for the Gilmore Girls? Yeah, they could never.

So ahh, anyway. This spaghetti squash! Other than the fact that it’s delicious and healthy, it also includes some of my favorite Italian flavors. Garlic, red pepper flakes and parmesan. I know, that some of you may think the one cup of parmesan is a little indulgent, but when eating all spaghetti squash for dinner, you gotta add the cheese. You just have to!

Although, if any of you vegan eaters are wanting to make this dish, I think subbing this vegan parmesan would be incredible. It will not melt into the pasta like real parmesan, but the flavors it will give are going to be SO GOOD. So if you are at all opposed to cheese, I high recommend going this route. Then this dish would be one hundred percent vegan – cool. cool.

The rest is honestly so simple. Roast your spaghetti squash, cook the olive oil, garlic and crushed red pepper until fragrant and the garlic has caramelized. Add the rainbow chard, the squash and the cheese and toss, toss, toss.


Eat. YUM.

The rainbow chard was a last-minute addition. I’ve been eying it on the grocery store shelf for the last couple of weeks and wracking my brain for a fun way to use it, it’s just so pretty. But for some reason I just could not think of a fun or different way to use it up. I kept thinking about using it in soup, but kind of felt like, “been there done that”. Then, as I was planning this healthy version of Spaghetti Squash Aglio E Olio, I knew that the chard would be the perfect green addition to round out this already veggie packed meal!

If you wanted to add a little protein to the dish, I’d recommend some garlic shrimp or roasted chicken. You could also add lentils for a veggie option!

I am all about all the pasta though…or I mean squash, but I swear this tastes just like pasta. HONEST.

    1. Hi Kelly,

    I made this recipe and my family loved it! I loved it too if course and saving this one for the books.

    Once the spaghetti squash is cooked, this comes together very quickly and easily. I was glad for the healthy side dish, but wish it had just a bit more flavor. I think I’ll use feta cheese instead of (or in addition to) the parmesan next time, for a bit more zip. But overall, a yummy, easy, and healthy recipe!

    1. Hi Blayre,
      Fantastic! Thanks a lot for making this recipe, I love to hear that it was enjoyed! Have a great week:) xx

    Seriously had a spaghetti squash on the counter and Swiss chard in the fridge – never expected a search combining these two things would yield such an amazing recipe!! I reeeaallyyy let the garlic infuse in the oil and WoW! I skipped adding the extra water just because when it came to that step I tasted it and liked it just as it was!. Will def make again!

    1. Hey MaryAnne,
      Happy Friday!! Love hearing that you enjoy this recipe, I so appreciate you giving it a try! xxT

    This is such a great fall recipe! I halved it and added grilled garlic shrimp which was such a great suggestion. Perfect with some white wine ?

  5. Oh my gosh! I loved this! Made this tonight and ate it all!! I only had one small spaghetti squash so I used a little less garlic and used vegan Parmesan ( cashews and nutritional yeast) to make it vegan. Delicious! I will definitely be making it again … and again.

  6. Just made this for dinner. So simple yet so delicious! To make it a quick weeknight meal, I made the spaghetti squash in the Instant Pot using the pressure cooker – cooked in 15 min, so even better! Thanks for the tasty recipe!

  7. I’d love to read a review by someone who’s actually made the recipe??? Why do people leave reviews for recipes they’ve not tried. That’s not a review, that’s a comment. Irritating.

    1. Hi Shauna! They leave reviews based off of the photos I take and the recipe itself. I hope you understand.. xTieghan

    Made this tonight! First time making spaghetti squash ever & this was amazing!!! And never knew what to make with Swiss chard either. Can’t wait to make it again! Thank you for the recipe!

  9. Oh my gosh that was amazing. I was searching for what to do with my chard and then I found this recipe. I also had a spaghetti squash on hand and I wasn’t sure what to do with it. And then this. Yum! Even my husband gave it a 10. Thanks for sharing your amazing recipes.

    1. So perfect! I am really glad this recipe turned out so well for you Jill! I hope you continue to enjoy my recipes! xTieghan

  10. I have made this recipe so many times and it is perfect. Unfortunately, I bought all of the ingredients to make this dish and purchased kale instead of chard! Don’t like it quite as much, but the substitution still worked out great.

    I didn’t have parmesan, so replaced it with cheddar but oh my God!!! What a delicious meal! I didn’t expect that good of a harmony between the ingredients. This is not a simple dish but a gurme dish 🙂 thank you for sharing.
