Is Spaghetti Keto-Friendly?

Let’s break that down, first the noodles, then the sauce.

How Many Carbs Are In Spaghetti Noodles?

Regular Spaghetti noodles are made with milled wheat. As a result, they contain about 30 grams of net carbs per 100 grams.

It is not keto-friendly at all! You would reach your daily macro with just 3 ounces of spaghetti, and that’s with no sauce at all!

That’s why I am using zero-carb noodles, a keto-friendly spaghetti in this recipe. Read more about that below!

Is Spaghetti Sauce Keto?

There is a great number of spaghetti sauce recipes out there.

I am a big fan of the Bolognese sauce, and this recipe is inspired by the traditional Spaghetti Bolognese recipe.

A traditional Bolognese sauce has about 5 to 8 grams of net carbs per 100 grams. Which again is not particularly keto-friendly.

So keep on reading to learn how I make a keto-friendly spaghetti sauce!

How To Make Keto Spaghetti And Meatballs

I learned this recipe from an Italian friend, so it has some deep traditional roots.

Key Ingredients

The two magical ingredients that create a super tasty keto spaghetti and meatballs recipe with juicy beef meatballs are:

  • Zero-Carb Noodles. I love Wonder Noodles because they have zero net carbs or calories. In fact, these keto spaghetti noodles are made of water, yam fiber, lime, and oat fiber. Another option for this keto spaghetti recipe is to use shirataki noodles or homemade zucchini noodles, also known as zoodles.
  • Diced chicken liver. The meatballs are hand-shaped with a mix of minced beef and finely-diced chicken liver. If it’s the chicken liver that makes you doubt this recipe, don’t! Give it a try. As the keto spaghetti sauce simmers for a while, and because the liver is finely diced, it doesn’t taste like liver at all. It simply makes the meatballs super tender, and they melt in your mouth.

I would never have thought that I would eat chicken liver before she made me this recipe.

Making The Keto Meatballs

The keto meatballs are one of the secrets of this recipe. To make them, slice the chicken liver finely and mix it with ground beef, Parmesan, herbs, and salt.

Then, shape and cook 20 meatballs with onions and garlic.

Tip: Deglaze

Deglaze with beef broth to add a delicious taste!

For a slightly different meatball taste, try my Gluten-Free Meatballs.

Making The Zero Carb Pasta

The zero-carb keto pasta is very easy to cook! They essentially behave like regular spaghetti.

Tip: add a pinch of salt to the boiling water!

Serving The Keto Spaghetti And Meatballs

To serve this delicious keto dish, put a quarter of the spaghetti in a bowl with a quarter of the meatball and sauce.

Add some grated Parmesan on top for a true Italian taste!

Storage Instructions

Like regular spaghetti, this keto spaghetti can easily be stored in an airtight container in the fridge for two to three days.

You can also freeze leftovers in an airtight container for up to three months.

Defrost the day before eating and rewarm in the microwave or saucepan.

Frequently Asked Questions

Can You Eat Spaghetti On Keto?

No, not regular spaghetti. Since classic spaghetti is made with wheat flour, it is way too high in carbs.
You have to use low-carb spaghetti and a meatball recipe that reduces the carbs like this one.

How Many Carbs Are In Keto Spaghetti And Meatballs?

This recipe has only 6.4 grams of net carbs per serving and only 365 calories.
So it is a great pasta recipe on your keto journey!
I use keto-friendly Zero-Carb spaghetti to make this keto spaghetti and meatballs recipe, but spiralizing zucchini into zucchini noodles would also work well.
I love Wonder Noodles as they contain no carbs, no calories, and the texture is firmer than regular keto noodles.

  • In a bowl, mix the minced beef with finely diced chicken liver (or ground chicken if you don't like liver), grated parmesan, dried herbs, and salt.
  • Shape meatballs with your hands and form 20 meatballs.
  • In a large saucepan, under medium heat, warm olive oil.
  • Add the crushed garlic and diced onion, reduce to low heat and cook for 2 minutes until golden and fragrant.
  • Add the meatballs into the saucepan and fry the meat for 2-3 minutes on all sides.
  • Add the beef broth to deglaze and stir in the can of diced tomatoes.
  • Cover and simmer for 20 minutes or until the liquid slightly thickens and reduces.
  • Adjust with salt and pepper to taste.
  • Meanwhile, cook the wonder noodles following your packing instructions. If you can't find these noodles, you can make your zucchini noodles with a spiralizer or try shirataki spaghetti.
  • When the keto noodles are cooked, serve 1/4 cooked noodles per plate (or more, they have zero carbs, so they won't impact carb count, but they will add fiber). Top with 1/4 of the whole meatball sauce.
  • Serve with 1/4 cup of grated parmesan.


  • You can freeze the leftovers in an airtight container or store them for 2 days in the fridge.
  • Defrost the day before eating and rewarm in the microwave or saucepan.


If you are using zucchini noodles, they will add 2 grams of net carbs per 3.5 oz (100 g)

    4 Thoughts On Keto Spaghetti And Meatballs With Zero-Carb Noodles
  1. 5 stars
    Hi Carine

    I recently borrowed your book Clean Bakery from our local library in Te Aroha and loved it so much – I didn’t want to return it!!! So have now purchased a copy of my own. I’m loving all the recipes in your book and wanted to see if you had a ‘savoury’ version. So I am so happy to have found this site which gives me lots more of your sweet recipes and also the savoury! (Although you can’t beat sitting down with a cup of tea and perusing a beautiful cookbook!) Thank you so much for your inspiration and your healthy alternatives to our favourite recipes and yours from France! Keep up the good work! 🙂


    • Kia ora Victoria! I am so happy to read your comment. Unfortunately I only wrote one cookbook in New Zealand and it is a sweet one. The rest of my low carb baking recipes are here on the blog, for free. I also love to read books so I totally get the frustration to navigate through a blog but my passion is to write here and I hope you will enjoy every recipe I post. Enjoy the recipes, XOXO Carine.

  2. I truly believe that there’s never a bad time for spaghetti and meatballs. For some reason, it’s the dish that just makes me feel comforted and happy and content no matter what’s going on in my life– not sure if that’s from the carbo-high or my childhood memories, but either way I totally love it! Need to try this recipe soon!

    • Hi Karly, So true ! it is the kind of simple comforting dish we could eat all year long right? Tell me if you like this recipe. I very enjoy the addition of chicken liver in the meatballs it makes them extra juicy and tender. See you soon on the blog! Merry Christmas too! Carine.

The nutrition data is calculated using WP Recipe Maker. Net Carbs is calculated by removing the fiber and some sweeteners from the total Carbohydrates. As an example, a recipe with 10 grams of Carbs per 100 grams that contains 3 grams of erythritol and 5 grams of fiber will have a net carbs content of 2 grams.
