This Southwestern spaghetti squash is now one of my latest raves. This humble squash is so versatile and you’d be amazed how many wonderful gluten-free plant-based dishes you can create using this vegetable.

I love stuffed spaghetti squash so much I had to include a recipe (Spaghetti Squash Pad Thai) into my cookbook, Healthier Steps 125 Gluten-Free Vegan Recipes. This Southwestern stuffed spaghetti squash is another winner. By the way, if you have never prepared spaghetti squash you are in for a real treat.

The flesh transforms into spaghetti-like strands when cooked, isn’t that amazing! Yes, you just use a fork to pull the strands apart, simple as that.

    Very delicious recipe. Great flavors and certainly made squash more interesting. PLEASE NOTE: I needed to more than double the amount of cashews to make the “cheese” Sauce reasonably thick. If you wanted a really runny sauce, you could make it as stated, but if you want something a bit thicker, I’d at least double the amount of cashews.

    I’ve made this a few times and it’s becoming one of our favorites. I make extra sauce to use it on other meals, too. Even the meat-eater in the family enjoys it.

    I’ve been trying vegan/vegetarian dishes for the past couple of weeks. It’s been a collection of hit or miss meals as far a flavor goes. My main issue is keeping my wife and 2yos happy. This dish was our favorite so far! The cheese sauce might be my new go-to for anything requiring a melted cheese. It is phenomenal! Thanks for the delicious recipe!

    First visit to your site, but I will come back! We are on a very limited diet–no dairy, sugar, meats–for health reasons as well as others. This recipe looks awesome and possibly will fulfill our craving for our favorite foods–Mexican! Is there some way to make your recipes so that they can be printed up? I am trying to put together a recipe book for us so I don’t have to search on the internet every time I want to fix a meal.

      The Print button is a green tab right below the title of the recipe. Once you hit print, scroll to where it says pages and choose the pages where the recipe is located, so if it is page 4 and 5 put 4-5 and then 1 copy and print. This is how the recipe card is built and I cannot make any changes to it because I’m a recipe creator and I have just a little clue when it comes to technical things. I will talk to my web developer more about your concerns. I actually just print the recipe and it printed fine for me. I have to print my recipes on a regular basis for cooking classes.

    Made this last night. Hubby is a meat and potatoes lover so….. He said it was as good as this “kind of stuff” can be. I guess that is praise. Mine didnt look as pretty as the picture above but it was tasty enough. Nothing terribly exciting but I really liked the “cheese” sauce. In fact, tonight I made a corn potato chowder that was very, very bland so I added the cheese sauce from this recipe to it. What a difference!!

      Wendy, thank you for your feedback. I’m so happy that your hubby tried it and you enjoyed the cheese sauce. Now I really need to put my corn and potato chowder recipe up, thank you for the reminder.

    Not vegan but I love spaghetti squash, which is how I found this.

    THIS IS THE BEST THING I THINK I’VE EVER EATEN. Seriously, I’m in love. I had doubts about the “cheese” sauce but holy cow it is fantastic. I added diced jalapenos in addition to the cayenne because I like a good kick, and otherwise I followed the directions exactly.

    I cannot communicate how much I loved this. Thank you for introducing me to my favorite dish (pho’s in a distant second place now, ha).

        UPDATE: For the first time in longer than I’m proud of, I didn’t have to throw away any leftovers-I finished all of it (very rare in my household of one). That’s how good this is. If this is what vegan is all about, I’m a believer. Thank you so much for this recipe!!!

    I made this tonight for dinner, and my husband and I both enjoyed our southwest spaghetti squash with cashew cheese very much! I wanted something different to do with my squash and this was perfect. We enjoyed them as our main course. Very delicious, filling and satisfying! Thanks for sharing !

    I made this recipe three weeks ago since I’ve cut meat, dairy and bread out of my diet for a month and it was easy and simply delicious. I’ve share with others and they too love it. It was so good I’m making it again right now as we speak. Thanks for sharing it.

      Still making this, almost a year later… and still loving it (as a non-vegan). Easily my favorite thing to cook and eat. The sweetness of the squash is balanced perfectly by the savoriness of the peppers, onions, and beans. This is my go-to for meatless Mondays (and sometimes Tuesdays, Wednesdays, Thursdays, Fridays…)

      It is the cashew cheese sauce. The recipe was included.

    Another beautiful idea! I’ve only ever stuffed acorn squash but the thought just never occurred to me that any winter squash can be stuffed. Thanks!
