Zucchini noodles or zoodles are more than just an “alternative” to regular pasta – they’re a culinary treat! With all the creamy textures and crispy-bacon crunch of the Italian classic, this quick and satisfying keto recipe hits all the right notes.
4 servingservings


  • 1¼ cups 300 ml heavy whipping cream
  • 1 tbsp 1 tbsp butter
  • 10 oz. 275 g bacon or pancetta, diced
  • ¼ cup 60 ml mayonnaise
  • salt and pepper
  • 2 lbs 900 g zucchini
  • 4 4 egg yolkegg yolks
  • 3 oz. 75 g grated parmesan cheese, some more for serving


Instructions are for 4 servings. Please modify as needed.

  1. Pour the heavy cream into a sauce pan, and bring it to a boil over medium high heat. Lower the heat to medium low, and let boil for a few minutes until reduced by a fourth.
  2. In a large frying pan, melt the butter over medium heat. Add bacon to the pan, frying until crispy. Set bacon aside. Keep the fat warm in the pan, on lowest setting.
  3. Whisk the mayonnaise into the heavy cream. Salt and pepper to taste, and cook until mayonnaise is warmed through. Reduce temperature to low, stirring occasionally.
  4. Make spirals of the zucchini with a spiralizer. If you don't have a spiralizer you can make thin zucchini strips with a potato peeler.
  5. Place zoodles in a microwave safe bowl, and microwave on high for 3-5 minutes, until warmed through, yet have a fresh, crispy texture. If you don't want to microwave, you can boil the zoodles in hot water for 30 seconds.
  6. In a separate bowl, combine the egg yolks, diced bacon and parmesan cheese.
  7. Add the bacon fat and the warm cream sauce to the zoodles, tossing together until zoodles are completely coated. Ensure that this mixture is slightly warm, and then add the egg-bacon-parmesan cheese mixture to the zoodles, tossing all together (the egg mixture will scramble if too warm when combining).
  8. Divide between four plates. Top with a generous amount of freshly grated parmesan.

Vegetarian keto carbonara

You can easily turn this recipe into a vegetarian keto dish! You can just skip the bacon and instead you can add some olive oil to your keto carbonara after combining the zoodles with the parmesan mixture.


If you prefer more of a crunch, don’t microwave the zoodles. Instead, add the warm bacon fat and sauce to the raw noodles, toss together, and enjoy.

    I'm confused... what do you do with the yolks at the end?
  3. carol
    I didnt bother with the eggs
  4. Zoe
    I think the raw egg yolks go into the warm dish to cook gently and make the sauce rich and glossy. In fact a classic carbonara wouldn't use any cream at all - only raw egg yolks. I'm going to try the Diet Doctor version though, as it sounds delicious.
  5. Krista
    So is the zucchini raw?
  6. Krista
    Amazing! I didn't use the egg yolks either. I also sautéed the zucchini in the bacon grease instead of drizzling it on top. Yum!
  7. Caroline
    Just made this for lunch. Amazing, didn't use the egg yolk, fried the noodles in the bacon fat, highly recommended.
  8. Rachel
    So good!!!!!!!!!!!! I made mine with turkey strips and mushrooms. I added the zucchini strips at the end and heated them for 2 minutes maybe? They were soft but not mushy. I did use the egg yolk - simply added it to my dish before eating and the egg cooks enough for sure. Delicious!!!!!!

    I wish I could see all nutrition info for this recipe to add in MyFitnessPal.

    Destiny you can add recipes to MyFitnessPal directly in the app. after you select what meal you are adding to tap recipes at the top, then click create a recipe, then add from the web and you can copy the link directly in to myfitensspal. works great.

    Definitely one of my favourite recipes thus far. Very tasty, and I loved the "zoodles".
  12. Andrea
    Sooo yummy! This is possibly my favourite LCHF recipe, and it really hits the spot as far as a creamy pasta substitute goes. Even my husband (who doesn't like vegetables) thought it was fantastic. I put the egg yolks in at the end, as per recipe, and mixed it all up so they just become a part of the sauce. Delicious!
  13. Mark
    Call it whatever you like, but certainly not carbonara... :)
  14. Kelli
    This may be a stupid question, but are the nutritional facts per serving or per recipe? When I did the calculations for each individual item per serving, it didn't match these numbers.
  15. Christine
    were can I find keto recipes just for Dinners?
  16. Donna
    Loved it!! I added garlic and mushrooms, and at the end I added some chopped Basil... Very good! but I didn't add the eggs either! (I forgot! ;)
  17. Pennie Morgan
    Would this freeze well? Anyone tried?

    Hi guys sup. The food was really nice and I just had t

    A typical carbonara recipe would have you mix them in at the end while it's all still on the stove. Add beaten eggs and cook, tossing constantly with tongs or large fork until eggs are barely set. Quickly add 1/2 cup Parmesan cheese, and toss again. Add salt and pepper to taste (remember that bacon and Parmesan are very salty). Peace :)

    Just made this and it is AMAZING. I will definitely make this again.

    Can this happen without mayo?
    Is there a breakdown of the crabs by ingredient somewhere? I do not see how its more than 5.5 net carbs per serving?
  24. Nina
    Just made this with a few tweets, I added chicken breast, garlic and onions. It came out lovely, I also added the Egg yolks at serving which made it lovely. I questioned it but decided to go with it. Two of us added the yolk one of us didn’t, you could tell the difference and the one who didn’t add the yolk regretted it.
  25. maryse
    I mix my egg yolks with my cream then pour it in once the rest is cooked, just simmer a few minutes and stir, done.
  26. Michelle
    The egg yolks get mixed in to the dish once it has been served. You stir them in on your plate while it's still warm. They make the sauce extra creamy and yummy.
  27. Alex
    This is not anywhere near Carbonara. There is no mayo, cream, or parsley in Carbonara. At all.

    Carbonara has butter, raw egg yolks, bacon, garlic, parmesan, course black pepper, and basil. That's it. Much better tasting. The black pepper is supposed to symbolize the carbon (coal) in the, the classic Italian 'coal miner's' dish.

    This was sooooo good. We added mushrooms and instead of all that mayo, we used 1 tblspn of avocado may and 2oz of cream cheese and half cup of whipping cream. Yum.
  29. Dione
    Hi Alex, zoodles aren’t pasta either! I’d love your quantities and method for proper carbonara please. Maybe D Dr will add it to the recipes for us. :-) To go with zoodles of course.

    Most calculator apps seem to over recommend protein and under recommend fat for some reason. We recommend keeping fat at about 70-75% of your calories and 20-25% from protein.

    I debated between giving this a 3 or a 4 stars but gave it a 4 because it really was good. It was VERY SOUPY, even after reducing the HWC. I added lots of salt and pepper and lemon juice to the mayo as it was so oily. I also added garlic to the pan as I cooked the zoodles which helped the dish not be so bland. I went ahead and added the egg yolk to the top but didn't find it added enough to make it worth it as the dish is already very rich.

    When you say soupy, did you mean from the cream or the zucchini? Zucchini noodles release so much liquid that I sweat them on paper towels for 30 minutes to an hour before cooking... turning them over frequently on the paper towels to absorb as much liquid as possible before. I'm going to try this recipe using this method!
  35. Marcin
    I don't care people say it's not real carbonara. It tastes great. I didn't even bother making zoodles, just cut zucchini roughly julienne style and fried it shortly in the fat from bacon. Unfortunately the sauce breaks if you want to reheat it the next day or I'm just unlucky.
