Pin It PIN IT!

Hi friends! Before we begin, I must announce the SUPER lucky winner of the Ted Allen cookbook! A huge huge HUGE thank you again to Robert Mondavi Private Selection for hosting this giveaway ūüôā Look forward to working with you more in the future!

And now! The winner!

aka, Mary Beth! Whose favorite ingredient is hot sauce! Sounds a bit ¬†like my hubby ūüôā Email me, Mary Beth, at to claim your prize!

Now, onto some seriously delicious food! But first I have to share this photo of Oscar. I was prepping in the kitchen yesterday and he just sat and watched me with his¬†tongue¬†hanging out. Honestly just the cutest. Plus, I’m sad b/c he has to get his routine shots today. So please, shoot this furbaby mother¬†some¬†reassuring thoughts, mmk?

He looks like a little e-wok doesn’t he? Oh that face! I could easily gush about him for the rest of my life, but I must restrain so I can talk about THIS. THIS-A BEAUTIFUL THING RIGHT A HERE. (I sometimes talk with an Italian accent. And a British one. Don’t judge me.)

Or better known, in it’s scientific term, as a big ol’ pile of awesome. Or, in lamens terms, spaghetti squash roasted to perfection, paired with sauteed asparagus, mushrooms and onions. Then! It’s garnished with a dollop of this stuff.

Homemade pesto! MMMMM! I’ve never been a huge pesto person. I mean, it’s good but I’m never like “Oh man. I just wish I had a spoonful of pesto!” Well, friends, that was before I made a batch of it at home. This stuff? Tastes like happiness. I would drink it through a straw if everyone around me wouldn’t disown me and put me in a straight jacket. It’s good. Plus, paired with this dish? It’s outstanding.

The pesto adds creaminess while the asparagus lends a superior crunch. If I closed my eyes, I wouldn’t know I was eating a vegetable. That is probably one of my favorite things about spaghetti squash. It’s such a FABULOUS¬†alternative¬†to pasta.

Even though the flavor is awesome, what makes me the most giddy about this dish is the simple fact that it has less than 6 points per 1 cup serving. 6 POINTS! Now that is a cause for celebration.

NOTE: You only need like 1 – 2 tablespoons of pesto to get that flavor. The more you add, the more fat and calories you add to the dish.

Spaghetti Squash with Veggies and Homemade Pesto

Serves 4 [pesto makes 1 cup]
Prep time: 45 minutes
Cook time: 20 minutes


For the pesto: 

  • 2 cups fresh basil leaves
  • 2 garlic cloves
  • 1/3 – 1/2 cup Parmesan cheese (freshly grated, if possible)
  • 1/3 cup walnuts, chopped
  • 1/2 cup olive oil
  • 2 tablespoons lemon juice
  • Dashes of salt and pepper
For the dish:
  • ¬†1 medium spaghetti squash, halved and seeded
  • 3/4 pound asparagus, cut into thirds
  • 1 cup mushrooms, chopped
  • 1 onion, chopped
  • 1 tablespoon olive oil
  • Dashes of salt and pepper


  1. To prepare the pesto, place walnuts, oil and basil leaves into a blender or food processor.  Pulse on low until creamed. Add in cheese, lemon juice and garlic cloves and continue to pulse until mixture is creamy and mixed. Add additional salt and pepper to taste. Cover and chill in the fridge.
  2. To prepare the dish, preheat the oven to 375F. Place the squash flesh side down in a jelly roll pan. Fill the pan with 1/2 inch water. Bake squash for at least 35 – 40 minutes, or until you can easily pull the “noodles” out with a fork. Let cool for 5 minutes.
  3. While squash bakes, prepare veggies. Heat olive oil in a medium pan over medium high heat. Add onions and cook until just translucent, about 3 minutes. Add in mushrooms and asparagus and cook until asparagus is soft, about 5 more minutes. Remove from heat.
  4. Once squash has cooled, carefully pull the flesh from the squash using a fork [this will give you the noodles]. Place in a bowl. Add in veggies and mix up with a tong. Add 1 – 2 tablespoons of pesto, stir and enjoy!

    This looks really good!  I have been wanting to try spaghetti squash as an alternative to pasta for awhile, but I am not sure I could get it past my family.  Scared!!

    This looks absolutely amazing. I made spaghetti squash once and butchered it. I should really try it again, especially with this recipe. Pesto and asparagus...two of my favorites.

    Yum!  And I love your furry baby, too.  Does he mind getting his shots because mine doesn't seem to care as long as there are enough people around for her to lick and jump on :)  Spaghetti squash always reminds of a roommate I had years ago who made spaghetti squash alfredo that made you forget it wasn't pasta.  Never been able to replicate it...

    Spaghetti squash is such a fall farmers market favorite but I haven't made one in months. I might have to "cheat' and pick one up at the grocery store, because this recipe looks delicious. It's funny -- I never make pasta (the same 2 boxes of pasta have come along on my last 2 moves) yet I love pasta-like dishes.

    I adore spaghetti squash but usually end up serving it with a bit of garlic and oil or a splash of tomato sauce.  Thank you for the inspiration!

    Mmm. This looks delicious. Love the carb count on this dish. You could even up the protein a bit by adding some grilled chicken...I need to go to the store immediately.

    Made this tonight with a few was great! For the spaghetti squash...I find that it's so much easier to cut by just baking it whole and not slicing it first...I pierce it all over with a knife and put it on a baking sheet for 80 minutes at 375...rotating it once halfway through.  Let it cool, slice down the middle, and proceed like normal! :)

    This is yummy! -- but I used HALF the olive oil, and added a little salt and pepper to the pesto. Also, I used yellow beans (just blanched) instead of asparagus -it's what was in my CSA box :) Thanks!

    I searched the web for a pesto spaghetti squash recipe and found your blog. So glad I did! This dish is delicious! I'll definitely make this again! I added a clove of garlic, a few sun dried tomatoes, and shrimp. Thanks for the inspiration!

    I am going back on the South Beach Diet and decided to look on the internet for a spaghetti squash recipe that had the veggies I had on hand tonight. So glad your's popped up first. I pretty much did your recipe with the pesto altho I used a scallion instead of a onion. Looking forward to making it again! Thanks
