Creamy Avocado Spaghetti Squash Pasta + How To Roast Spaghetti Squash

« Jump to Recipe »

how to roast a spaghetti squash-6663

Somehow, I managed to live the first 25-26 years of my life before trying spaghetti squash. Actually, I could add many, many foods to that list. When I first came across spaghetti squash, I didn’t quite know what to think of it. Stringy strands of squash? How the heck do I get that to work? It seems weird. Naturally, this only made me want to try it more!

Well, it is a bit weird when you think about it, but it’s also now one of my favourite foods. I could add many things to that list too.

Similar to my beloved zucchini noodles, spaghetti squash makes a light, fiberiffic base for pasta sauce, pesto, chili, stews, and even my creamy avocado pasta sauce. It’s also a great way to up your veggie intake without even realizing it. I can easily pound back an entire squash all on my own. [Did I just say “pound back” and “squash” in the same sentence? Speaking of weird…]

This big squash (photographed) hails from Aylmer, Ontario – a hefty 5 pounder!

If you’ve ever been intimidated by preparing and roasting a spaghetti squash like I have, I hope these step-by-step photos are helpful.

Note: If you really, really don’t want to slice the squash in half, rest assured you can roast squash whole (just pierce it with a few knife cuts first). I prefer to slice it in half for a couple reasons: 1) I season the squash before roasting and the flavour infuses as it roasts, and 2) It cooks in a fraction of the time – often ~20 minutes faster compared to roasting it whole. However, roasting it whole is a nice option if you have a really big squash and a dull knife!

How I Roast Spaghetti Squash:

1. Preheat the oven to 375F. If your squash is quite large, start by slicing off the stem. This makes it easier to slice through and also gives you a flat base to work with. You can do this on a cutting board or an old tea towel.

2. Place squash flat end down. With a [recently sharpened] chef’s knife, slice down the middle lengthwise. I like to use a “rocking” motion to cut through. This big squash was challenging, but a slow and steady pace eventually won the race…or something like that.

3. With a metal ice cream scoop (my Zyliss scoop works amazing for this!) or spoon, scoop out the seeds & guts. Set aside seeds if you plan to roast them later. And you will, right?

4. Brush halves with a tiny amount of olive oil (I used maybe 1/2 tsp oil on each). Sprinkle with Herbamare (or sea salt) and freshly ground black pepper. Place on a baking sheet lined with parchment paper, cut side down. The salt & pepper you just sprinkled on will stick to the oil.

5. Roast at 375F for around 35-45 minutes, or until you can easily scrape strands away from the squash. The outer yellow skin will also deepen in colour. Baking time will vary depending on the size. My 5-pound squash took 40 minutes.

6. Remove from oven and flip each half. At this point, feel free to use the fork to see if the strands easily come off. If it’s ready, cool for about 5-10 minutes and then grab the fork and scrape the squash flesh over and over. You’ll be left with a bunch of spaghetti-like strands! Season again and serve immediately – in the shell if you wish.

My 5 pound squash made just over 4 cups of “spaghetti” strands – the perfect amount for Eric and I to share.

Something as simple as salt, pepper, marinara, dried basil, and garlic powder is a fantastic combo. I could eat this every. single. day.

I also love to serve homemade chili or stew on top.

Or in this case, creamy avocado sauce.

For this recipe, I played around with my creamy avocado pasta sauce. It was so good I had to share the results.

Creamy Avocado Spaghetti Squash Pasta, Fall Edition

Vegan, gluten-free, nut-free, soy-free
Yield
4 servings
Prep time
20 minutes
Cook time
35 minutes
Total time
55 minutes

Ingredients

  • One 4-5 pound spaghetti squash, halved and seeds scooped out
  • 1 tsp extra virgin olive oil
  • sea salt (or Herbamare) and pepper
  • 2 garlic cloves
  • 1/4 cup fresh basil
  • 2 tbsp fresh lemon juice, or more to taste
  • 1 tbsp extra virgin olive oil
  • 1 medium ripe avocado
  • Water, to thin out (I use around 2-3 tbsp water)
  • Fine grain sea salt, to taste (I use between 1/4-1/2 tsp)
  • Black pepper, to taste

Directions

  1. Preheat oven to 375°F. Wash spaghetti squash and place on an old tea towel (this helps prevent it from slipping) or cutting board. Slice off stem, flip cut side down, and then carefully slice it in half, lengthwise. Remove seeds + squash guts and set aside.
  2. Brush the cut-sides with oil and then season with salt and pepper. Place cut side down on a baking sheet lined with parchment paper and bake for 35-45 minutes, depending on the size of the squash. Squash is ready when the strands scrape off with a fork fairly easily. My 5 pound squash took 40 mins.
  3. Meanwhile, make the avocado sauce. Add the garlic and basil to a food processor and mince. Now, add in the lemon juice and olive oil and stop to scrape down the sides of the bowl.
  4. Slice avocado in half and pit. Scoop out the flesh and drop it into the processor with the motor running. Add water, 1 tbsp at a time, to thin out the sauce as needed. Stop to scrape down the bowl. Add salt and pepper to taste and process again. Feel free to add more lemon or oil, adjusting to taste, if desired.
  5. When the squash is ready, flip over and allow to cool slightly so it’s safe to handle. Grab a fork and scrape off strands of squash until you have two empty “shells”. Place strands onto a plate (or just serve in the shells), season with s & p, and top with the avocado sauce. Sauce will keep for 1 day in the fridge in an air-tight container.

We enjoyed the roasted squash seeds while watching some great fall tv! Anyone catch The Mindy Project this week? I’m pretty much obsessed with it after 1 show. Also, glad to have Up All Night back on – another show I never miss.

To my surprise, the seeds taste just like sugar pumpkin seeds. yum!

This creamy avocado sauce is a top notch recipe! You can’t imagine how delicious it is unless you make it. We roasted the spaghetti squash per directions and topped it with Muir Glen portabello mushroom sauce one night. We enjoyed every bite and, the interesting thing is, neither of us have ever liked spaghetti squash; so roasting this way changed all of that! Tonight dinner is: spaghetti squash with the creamy avocado sauce above. I know my husband is going to thank me and “you”, Angela for a special and tasty dinner! :)
