Monday was a funny day in the ‘kitch. That’s when I wrote this post.

I went over to my refrigerator with a plan to make a roasted vegetable pasta. Pretty simple, right? I was thinking roasted onions and honey-roasted carrots with slivered toasted almonds. Sounded good to me- a basic winter pasta. 

So, I chopped up all the vegetables and looked at my cutting board. It was too blah. Not enough flavor. 

I went back into the fridge and immediately saw my pearl onions I bought over the weekend, with intentions of slow roasting them for dinner one night, alongside some salmon. Well, goodbye dinner planning and hello blog recipe!

This bowl of pasta still has that roasted vegetable element but more dimension and flavor. By lightly marinading the pearl onions in balsamic vinegar, the onions absorb that balsamic flavor as they roast. When you dig your fork into this pasta, you’re met with a soft onion, soft zucchini noodle, tasty asparagus and crunchy pine nut. The pearl onions almost become glazed in the balsamic – they’re luxurious and surprising.

I’m happy I ditched the carrot and onion idea, because this may become one of my new easy go-to winter pastas. Blade A works perfectly here, because it offers a heartiness to an otherwise simplistic, light dish.

Did I forget the dusting of Parmesan at the end? Instead of mixing the Parmesan into the pasta in the skillet, I lightly dusted the dish, so the flavors of the vegetables really shine.

I loved this dish so much that I packaged it in a to-go container and brought it to my doormen. Let’s just say that I may quickly become their favorite resident. Tehe. Bribery always works!

Balsamic Roasted Pearl Onions, Asparagus & Toasted Pine Nuts with Zucchini Pasta

Prep Time10 mins
Cook Time25 mins
Total Time35 mins
Servings: 2


  • 6 asparagus stalks
  • olive oil to drizzle
  • 8 white pearl onions peeled*
  • 1/4 cup balsamic vinegar
  • 1/4 tsp dried rosemary
  • 1/2 tsp dried thyme
  • 1.5 tbsp pine nuts
  • 1.5 tbsp olive oil
  • 1 large garlic clove minced
  • 1/4 tsp red pepper flakes
  • 3 zucchinis Blade A
  • 1 tbsp grated parmesan cheese
  • 1 tbsp freshly chopped parsley


  • Preheat the oven to 375 degrees. Take your asparagus, snap off the bottoms and slice them into 2" pieces.
  • On a baking tray, place in your asparagus pieces and drizzle with olive oil. Mix together to coat and set aside.
  • Place the pearl onions and balsamic vinegar in a bowl and toss to combine. Place the pearl onions on the baking tray with the asparagus.
  • Season the asparagus and onions with salt, pepper, thyme and rosemary. Roast the vegetables in the oven for 25 minutes. Toss halfway through.
  • Place a small skillet over medium heat and add in the pine nuts. Let cook for a couple minutes. Once you can smell the pine nuts toasting, flip them over and cook another couple minutes or until lightly browned. Transfer to a bowl and set aside.
  • 20 minutes into roasting the vegetables, place a large skillet over medium heat and add in the olive oil. Then, add in the garlic, cook for 30 seconds and then add in the red pepper flakes and zucchini noodles. Toss the zucchini noodles for 2-3 minutes or until tender.
  • When done, divide the noodles into two bowls and top each with even amounts of asparagus and pearl onions. Top with 1/2 tbsp of parmesan cheese per bowl. Garnish each with parsley and pine nuts.


*To peel the pearl onions, you can soak them in warm water first for a few minutes to soften the outer peel. Once soaked, slice off the top and bottom and peel the outer skin off.

I made this dish over the weekend and it was yummy! But I think I may have misunderstood part of the directions. It says to combine the peeled pearl onions with ¼ cup balsamic vinegar, then add the onions to the asparagus in the roasting pan. I included the vinegar with the onions in the roasting pan, and it spread out and burned in the pan. Should I have drained it off before adding onions?

I drop a comment whenever I especially enjoy a post on a blog or I have something to add to the discussion. Usually it's caused by the sincerness displayed in the article I looked at. And after this post Balsamic Roasted Pearl Onions, Asparagus & Toasted Pine Nuts with Zucchini Pasta — Inspiralized. I was excited enough to drop a thought :-P I do have 2 questions for you if it's okay. Is it simply me or does it appear like a few of the remarks come across like they are coming from brain dead folks? :-P And, if you are writing at other places, I'd like to keep up with you. Could you make a list all of all your community sites like your Facebook page, twitter feed, or linkedin profile?

VEGETARIAN ZUCCHINI & QUINOA LASAGNA, a fan favorite 👏🏼😍 the zucchini cooks to just al dente for a real lasagna-like texture and the quinoa gives this vegetarian dish a burst of protein and texture. I love making this during the summertime with fresh zucchinis and basil, but it’s amazing year round ☀️ grab the recipe up on the blog! ⁣

the crib to bed and the nap to quiet time transitions all happened within a month or so of each other for us and today on the blog, I’m sharing all about how we got through them smoothly-ish 🤪 also, as just a general thought, all of these baby and toddler transitions tend to be “easier” than we hype them up to be. I think the anxiety of the unknown makes them scarier than they are! anyway, you can check the post out on the blog today for all the details! it’s a quick but to-the-point post ✌🏼 ⁣

and not to contradict myself 🙈, but I need all the tips for putting toddlers together in the same room, which I’m going to have to do soon, so we can start preparing the twins’ nursery (we’re planning on moving Luca into Roma’s room and using Luca’s room for the twins, because it’s larger.) moms/dads who have done it - what’s the secret?! 🤔⁣
