Your Go-To Lazy Weekday Meal

Some nights, you just need a dinner that practically makes itself. Enter this pesto spaghetti squash bowl—a recipe so easy and satisfying that it’s like dinner on autopilot!

Spaghetti squash noodles can be used just about like regular noodles, so in this recipe, we’ll mix in some pesto (get the homemade pesto recipe here), green healthy noms (spinach + broccoli + plus a few other non-green veggies), and feta cheese to make a quick, filling, low-carb “pasta” dinner.

The best part? The spaghetti squash doubles as your bowl—less cleanup, more time to enjoy your meal (or do other important things like binge-watch Netflix!). Whether you’re planning a cozy night on the couch or just looking for a veggie-packed meal, this dish is calling your name!

Here’s What You’ll Need

These lazy spaghetti squash bowls are super flexible, so add whatever veggies and toppings you have kicking around! Jump down to the recipe card for exact ingredient measurements—this is just an overview!

  • Spaghetti Squash: For the most important ingredient of the recipe, choose 1 medium-sized, golden-colored spaghetti squash.
  • Olive Oil: We’ll spread oil on the inside of the squash to help it tenderize.
  • Cherry Tomatoes: We’ll roast these for a deliciously juicy flavor.
  • Greens: Add some broccoli and spinach for flavor and nutrients!
  • Pesto: This dish needs a rich sauce to balance the veggies, and pesto works so well here!
  • Feta Cheese: Tie it all together with creamy, salt feta cheese.

Making These Bowls Is Too Easy

Step 1: Prep The Ingredients
Preheat the oven to 400°F (204°C). Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle the inside with olive oil and rub it around. Place cut-side down on a baking sheet and prick the outside with a fork. Spread the tomatoes out onto the same baking sheet.

Pricking the squash with a fork will help steam escape during roasting, preventing a squash explosion in your oven (yes, it can happen!).

Step 2: Roast The Squash And Tomatoes
Roast the squash and tomatoes for 30 minutes until the squash is fork-tender but still a little firm.

At this point, the tomatoes should be burst and lightly browned. Before moving to the next step, flip the squash over and let it cool enough to touch.

Step 3: Cook The Broccoli
While the squash bakes, place the broccoli in a microwave-safe bowl and cover it with plastic wrap. Microwave until tender.

Step 4: Saute The Veggies
Lightly grease a large saute pan and set over medium heat. Add the broccoli and spinach, cooking until the spinach has reduced in size.

Step 5: Spaghettify The Squash
Use a fork to scrape strands from the inside of the spaghetti squash. Transfer the strands to a separate bowl.

If you’re using the spaghetti squash as bowls, leave about ¼ inch of flesh in the squash to support the bowls as you eat.

Step 6: Assemble The Bowls
Finally, add the spaghetti squash noodles, tomatoes, pesto, and feta to the pan with the spinach and broccoli. Gently stir to combine, optionally spooning back into the spaghetti squash shells to serve.

Feel free to toss in some cooked chickpeas or roasted tofu for an extra protein boost that makes it even more satisfying.

Picking The Perfect Spaghetti Squash

Choosing a squash is like choosing a watermelon (or a box of chocolates). You never quite know what you’ll get… unless you know what to look for! Here are some pointers for choosing the best, ripest, juiciest squash your local farmer’s market or grocery store can provide.

First, you’ll want a squash that feels heavy and dense, and the skin should be quite thick. This usually means it’s ripe and ready to eat! Soft spots are a no-no, as these are usually bad spots and will need to be cut off. Color-wise, golden yellow or dark yellow means we’re in business!

    How does this how so many grams of fat.. how can I get it down?

    1. Sarah says:

      Hi Greg! Between the pesto (which is an olive oil based sauce), the olive oil used in cooking, and the feta cheese, this is pretty high in fat. You can definitely try to reduce this by using the olive oil more sparingly, halving the pesto (and perhaps mixing the pesto with a bit of Greek yogurt so you still get a nice creamy sauce), and cutting back on the feta cheese.

  2. Dakota says:

    By one half of recipe do you mean one half of the squash with the broccoli and spinach inside or do you mean one half of the one spaghetti squash half with ingredients.

    1. Sarah says:

      Hi Dakota! Sorry for the delay. I mean one half of all the ingredients, so including the broccoli and fillings 🙂

  3. Karen says:

    Can a spaghetti squash be too light yellow to use, my husband brought one home from the grocery and it’s such a light yellow that I thought it might not be ripe enough… then what do I do??

    1. Sarah says:

      Hi Karen! If you haven’t cut it yet, you can let it ripen a bit by setting it in a warm, sunny area. It should turn golden when it is ready 🙂

    This looks so good and with all that nutrition there is room for dessert during the Criminal Minds marathon.

    1. Sarah says:

      😅 EXACTLY! Enjoy! 😀

  5. Jules says:

    I assume the tomatoes get added in at the end along with the squash, pesto and feta? They are mentioned at the beginning, but never again in the rest of the recipe and aren’t showing in the picture of the finished product.

    1. Sarah says:

      Thanks for pointing that out, Jules! They should be stirred in with everything at the end 😀
