Zucchini Noodle Spaghetti Bolognese

This zucchini noodle spaghetti bolognese is reminiscent of an Italian beef ragu, but better. Fresh zoodles are warmed up with a layer of rich bolognese, then topped with basil and parmesan. It’s an easy weeknight meal the whole family will love!

With zucchini season just around the corner, you know what that means. More zucchini recipes for your summer menu! And if you loved my zucchini lasagna, you’re sure to love this healthier spin on a classic.

It’s a simple combination of zucchini noodles and bolognese sauce. And instead of using a store-bought pasta sauce, we’re making it from scratch today. But don’t worry. It’s easier than you think and adds that vine-ripened freshness to this summer plate. 

What Is Bolognese?

When you hear bolognese, you’re probably thinking of a meaty tomato sauce. But, it’s much more than that. It transforms ground beef into something rich and appetizing.

Traditional Italian bolognese may include vegetables such carrot and celery, in addition to the meat, onions, and tomatoes. But since we’re serving the bolognese sauce on top of vegetables today, we’re keeping the sauce simple yet flavorful.

Creating An Easy, Simple Bolognese Sauce 

While you can certainly use store-bought pasta sauce in this recipe, give this homemade version a try for fresh, herby goodness. I’m using beefsteak tomatoes for this recipe. But you can use plum or roma tomatoes (which have less liquid) to speed up the cooking process. Here’s how to make it. 

Process the tomatoes. First, slice the tomatoes into quarters and toss them into a food processor. Pulse a few times until it’s slightly pureed. 

Saute and boil. In a pot over medium heat, saute the diced onions and garlic, then stir in the tomatoes and oregano. Your sauce will thicken in about 30 minutes after much of the water has evaporated.

Cook the beef. While the tomato sauce is cooking, saute the ground beef in a large pan until it’s browned. 

Mix everything together. Add some tomato paste to the sauce (which helps to thicken a bit more) and finish it off with salt, pepper and fresh basil. Then, pour the sauce into the pan and mix it in with the beef. And you’re done!

The Best Zucchini Noodle Spaghetti Bolognese

Now that your sauce is ready, all you need to do is spiralize the zucchini. In previous recipes I’ve cooked the zucchini, but today I’m keeping the zucchini raw for a more crisp texture.

With room temperature zucchini, the heat of the bolognese sauce warms it perfectly. But if your zucchini is refrigerated or you prefer it slightly cooked, there’s a few things you can do after spiralizing. 

  • Sauté the zoodles with a little bit of olive oil for one minute
  • Blanch in a pot of boiling water for one minute
  • Microwave the zoodles for one minute

When you’re done, add a serving of zucchini noodles to a plate and top with bolognese sauce. Then, garnish with grated parmigiano reggiano and fresh basil. Voila – zucchini noodle spaghetti dinner!

Bolognese Variations

Not a fan of beef? No problem. Here’s a few substitutions that will still create a delicious “meaty” mixture. 

  • Chicken or Turkey: use ground chicken or turkey for a lighter, low-carb option.
  • Vegan Mushroom and Walnut Mix: Saute chopped mushrooms until cooked. Then add in grated carrots, onions, chopped walnuts, minced garlic and saute for another 4 minutes. Let this mixture cook with the tomato sauce.

This zucchini noodle spaghetti bolognese is a healthy, gluten-free weeknight dinner the whole family will love.


  • 1 lb ground beef
  • 4 large zucchini

  • 1/2 onion, diced
  • 3 cloves garlic, minced
  • 1 tbsp olive oil
  • 1/2 tbsp dried oregano
  • 2 tbsp tomato paste
  • 1 1/2 tbsp fresh basil, finely chopped
  • 1/4 tsp sea salt
  • pepper, to taste
  • parmigiano reggiano, grated for topping (optional)

  • Slice the tomatoes in half, remove the core and quarter. Place in a food processor and pulse a few times, until finely diced and almost pureed.

  • Heat the olive oil in a pot on medium heat and saute the onions for 2-3 minutes or until slightly translucent. Add the garlic and cook an additional minute.
  • Add the tomatoes and oregano to the pot, then stir and simmer uncovered for 20-30 minutes or until the sauce has thickened and much of the liquid has evaporated.
  • While the sauce is cooking, spiralize the zucchini with either a spiralizer or julienne peeler and set aside.
  • Add the ground beef to a saute pan and cook on medium-high heat. Use a wooden spoon or spatula to break the ground beef up into small pieces as it cooks. The beef is done when it's browned and cooked through.
  • After the sauce has reduced, stir in the tomato paste, fresh basil and salt and pepper. Cook for another 2-3 minutes, then add to the cooked ground beef and stir to combine.
  • Add a serving of zucchini noodles to a plate and top with bolognese sauce and grated parmigiano reggiano. Garnish with additional basil.

  1. So you suggest to saute the noodles and zucchini in better before serving?

    • No, there’s no need to saute the noodles before serving. You can read more about prepping zucchini noodles in my “how to make zucchini noodles” post!

  2. We have been enjoying your recipes SO much! Everything we’ve tried was delish!! 5 stars

  3. This is absolutely delicious! I used whole tomatoes and added one link of mild Italian sausage to the ground beef. Fresh basil really enhances the dish. This will be a regular favorite.

  4. Much better with fresh tomatoes 👍5 stars

  5. Hello Lisa,

    thank you again for a great recipe! Can canned tomatoes be substituted for the fresh tomatoes? And can the zoodles be food prepped? If yes, how long will it last for?

    • Hi there! You can use canned whole tomatoes if you’d like. As for zoodles, they can be prepped and stored in the fridge for a few days :)

  6. How many cups of tomatoes would this equal? It’s hard to know what size of tomatoes you expect. Thanks!

    • Hi Amanda- Just 10 regular tomatoes are fine, and if you have smaller tomatoes (such as roma tomatoes) then around 12 works.

  7. Hi Lisa! 

    I love your site – content, pictures, the works :) ! 

    Thank you for including the clarification re: Registered Dietitians and other Registered Health professionals practicing in the Medical model and for hi-lighting the scope of these professionals who are trained to work with clients in disease states and/or managing chronic diseases.  

    Your nutrition content is top notch as a Health Coach.  It’s great to see the evidence you cited for wellness programs enhancing behaviour change and that there is a role for Health coaches to work with healthy clients – provided scope of practice is adhered to and clients are informed of the same. 

    In terms of the bolognese recipe..  your ground beef sub lists ground chicken or ground turkey as a “low Carb” option.   Perhaps an edit is required as subbing the meat sources does not affect the carbohydrate nutrition profile. 

    Kind regards,

  20. How many Calories and carbs per serving. And how much is 1 serving? Is it one ounce? Or 2? Just trying to get my macros right and on point.

  21. Can I use Turkey in this recipe?

  22. How long does the Bolognese sauce last in the refrigerator? 

  23. Just getting into “zoodles”. Borrowed my daughter-in-laws spiral and love using it. Used to day for first time. I think I still need to practice cooking the zoodles. I put it with some left-over sauce and warmed it all up. Still a little crunchier than I want, but still tasted yummy. I will definitely be purchasing my own spiral and making more recipes.
    Thanks!5 stars

    • Glad you like it! Share a pic and tag me – I’d love to see! :) x

      • I tried to take a picture, but nighttime kitchen lighting is the worst, and just didn’t do this dish justice….
        Such a great recipe!
        There was a teeny bit leftover, and I was able to microwave it all together, and it reheated perfectly! The moisture from the warmed up zucchini noodles didn’t even water down the sauce at all. :D
        Thank you, Lisa!!

      • Oh, I totally understand kitchen lighting – lol! And I do the same on the leftovers. Love making one meal for two days (and only having one set of dirty pots and pans!). ;) x
