Best Ever Spaghetti Carbonara - Slimming Eats Recipe (1)

Easy Carbonara

I wanted to put together a spaghetti carbonara recipe (one of my fav pasta dishes ever) that was still really yummy but also light on the calories to a traditional carbonara and oh boy! did I achieve that. It isdelicious.

Ingredients for Carbonara

The ingredients for carbonara are pretty straight forward and despite what some think there is no cream added to a traditional carbonara, that creamy finish comes from eggs, parmesan (Parmigiano-Reggiano) or Pecorino Romano, and some pasta water. Please don't be tempted to ruin this by stirring in something like Quark.

To make this carbonara you need:

  • Spaghetti
  • Eggs (whole and yolk)
  • Parmesan or Pecorino Romano
  • Lean Bacon
  • Garlic
  • Onion
  • Chicken Stock
  • Salt and Pepper

Simple ingredients, right?

How to Make a Lower Calorie Carbonara

Bear in mind there are so many different ways available to make carbonara and this is my method of what we like and might not be quite the traditional method. I tweak a few things to get the calories lower.

One thing is the the addition of stock, this is a ingredient I use for softening down vegetables without the need for adding lots of oil/fat. You just add a little bit at a time into the pan of the onion and garlic and cook it off before you add more. Don't add it all at once or you will end up with a watery mess. The result is a golden lovely softened base to your carbonara.

I tend to use parmesan cheese as it's what I always on hand, but you can use Pecorino Romano if you prefer, which is the more authentic ingredient.

Some of the measurement of cheese is mixed with the eggs and reserved pasta water, this is liquid gold and is what makes that silky creamy sauce appearance on the pasta, so don't be tempted to skip the pasta water step, it's a vital part of the recipe.

Instead of pancetta, I use lean back bacon, diced up and pan fried until golden, you get that flavour without the higher calories of pancetta

Lastly is the pasta and it's not spaghetti carbonara without spaghetti.

Additions to Carbonara

Although not traditionally found in a carbonara, I sometimes add in some sliced mushrooms with the onions and garlic, not a true carbonara when you include this, but is a great way to bulk out the dish and make it more filling, which is vital when watching the calories.

Sides for Carbonara

Other ways to make this a more filling meal is to include some healthy sides alongside the carbonara.

A bowl of mixed salad is my usual go to, with any of my salad favourites like baby greens, tomatoes, red onion, cucumber etc

But when I don't fancy a salad any steamed, sauteed or roasted greens are great - like tenderstem broccoli or asparagus etc. Remember this are just to make your plate more feeling and high satiety.

Best Ever Spaghetti Carbonara

Yield: SERVES 2

Prep Time: 10 minutes

Cook Time: 12 minutes

Total Time: 22 minutes

The best ever spaghetti carbonara - traditional flavours and ingredients and a dish you will want to make again and again.


  • 140g (5oz) uncooked spaghetti (gluten free can be used)
  • 4 slices of lean back bacon (fat removed), chopped up
  • 1 onion, thinly sliced
  • 2 garlic cloves, crushed
  • 30g (1oz) finely grated parmesan
  • salt and black pepper
  • 1 large egg
  • 1 large egg yolk
  • 240ml (1 cup) of chicken or vegetable stock
  • ⅓ cup (80ml) of the pasta liquid (once pasta is cooked)
  • spray oil

to serve

  • 30g (1oz) of parmesan
  • 2 tablespoons chopped fresh flat-leaf parsley


  1. Cook pasta according to the packet instructions.
  2. Drain, but keep ⅓ cup of the cooking liquid.
  3. Combine 30g/1oz oft the cheese, egg, egg yolk and a little salt and pepper in a small bowl, stirring with a whisk. Gradually add the reserved ⅓ cup cooking liquid (this ensures the egg doesn't scramble when you add it to the pasta) to egg mixture, stirring constantly with a whisk. Set aside.
  4. Spray a large nonstick frying pan over medium-high heat with some spray oil. Add the bacon and cook until golden. Remove bacon and set aside.
  5. Add the onion and garlic (also mushrooms if you are adding those) to the pan, and sauté until golden.
  6. This is where you will need the stock, if the mushrooms, onions and garlic start to stick, keep adding a little of the stock and continue this process until the stock is almost gone and the mushrooms and onion have a nice golden color.
  7. Add the pasta and bacon back to the pan; reduce heat and mix thoroughly.
  8. Add the egg mixture, remove from heat and toss in pan to evenly coat.
  9. Divide equally among two plates, season with salt and black pepper and sprinkle with some fresh parsley and the remaining parmesan cheese.
  10. Enjoy!!

  9. greenpixey says

    Great recipe. Just made this for me and my 3 children and we all loved it.
    Is this freezable or is it possible to leave any left overs in the fridge for later in the day?


    • admin says

      I am not sure it would keep well, because of the egg added to it and would most likely be best eaten fresh once made.


  10. Victoria Sawyer says

    it says its 2 hexa's on extra easy but we are only aloud one hexa on extra easy??


    • Siobhan (Slimming Eats) says

      it is 2 HEa's for the entire recipe. The recipe serves 2, so 1 HEa per person.

  15. Emily-Jane says

    Bloody lush! This will now become a weekly staple in our house!


  16. Kelly says

    Would you freeze this??


    • Shevy (Slimming Eats) says

      Hi Kelly, pasta is always best eaten once cooked, as it can become slightly soft when reheated. I am okay with slightly overcooked pasta, so do freeze pasta dishes, however as this one using a sauce which is made with eggs etc, I don't recommend freezing. Hope that helps.


  17. Claire Wade says

    This was divine. I did swap pecorino for parmesan but that's just a personal preference. Hubby loved it too which is always a plus. A great use of hexa. Will definitely be making a regular appearance in this house.


  18. Teresa Leahy O Brien says

    So for this are you using 1 full egg and an a extra egg yoke as well


    • Shevy (Slimming Eats) says

      Hi Teresa, yes that is correct 🙂


  19. Suzanne says

    This was the absolute best carbonara recipe I've had, thank you Siobhan I'll be making this a regular in my house x


  20. Elena says

    • Shevy (Slimming Eats) says

  21. Hilda Reid says

    Absolutely adore this receipe, thank you.

    This is the godfather of slimming world recipes. I tried this for the first time tonight and it is by far the best recipe I've ever made... not just slimming world friendly but ANY recipe. Better than the full fat version. Absolutely amazing.


  23. Cathryn Short says

    Just made this and omg it was gorgeous! So easy to make and my boyfriend loved it! Thank you so much for sharing this recipe


  24. Karen Graham says

    Made the carbonara for me and hubby tonight, I can definitely say it’s the best I’ve tasted by far, even hubby loved it and he’s not a big pasta fan, will definitely be making this again


  25. Sam says

    We love this dish! However, do you need as much (or any) stock if you are leaving out the mushrooms?


  26. Julie Hawkins says

    Can you just had chedder cheese instead of parmesan.


    • Shevy (Slimming Eats) says

      you could, but carbonara will never use cheddar, for that authentic taste a hard cheese like parmesan or pecorino is best.


  27. Connie says

    Such a tasty recipe, can’t believe it’s syn free!


  28. Janette says

    Just had this for dinner tonight it was amazing thank you.


  29. Vas says

    Hi, I’m looking at making this tonight, just had a question about the stock? Is the stock meant to all evaporate by the time you add the pasta in? Sorry I just got confused! Can’t wait to try this though!


    • Siobhan (Slimming Eats) says

      yes pretty much, the stock is used to cook, flavour the onions and mushrooms in place of butter or oil as in step 6. It will evaporate down really quick, just ensure you don't turn the heat too low, otherwise the mushrooms and onoon will just sit in stock.


  30. Laura Meyer says

    Fabulous carbonara recipe, can't believe its syn free, really tastes amazing!


  31. Rebecca says

    Oh my days. This really is sooooooooo good!


  32. Jacqui says

    I'd like to try this recipe but need to make it for 1 person. Could. I just add the one egg yolk?


    • Siobhan (Slimming Eats) says

      yes that should work, just half all the ingredients and use 1 egg yolk.


  33. Debbie says

    Made this tonight for the first time, I was amazed how good this recipe is, and as I can’t tolerate cream but love carbonara, I’ve missed out. Not anymore. Will definitely be my go to recipe. Thanks for sharing


  34. Lisa says

    Made this recipe last night and wow! What a game changer. I was really worried I would mess this up and end up with scrambled eggs but it didn't happen! It was actually so quick and easy to whip up and even the picky eaters loved it in my house. Thank you


  35. Becky says

    Hi I’m making this tonight and my son has just gone out saying he will have tea when he comes in, can this be reheated?


    • Siobhan (Slimming Eats) says

      I personally wouldn't reheat carbonara, it's best eaten when cooked.


  36. amy cunningham says

    made this today during my lunch time whilst working at home, incredibly tasty 🙂


  37. Sandra Jones says

    Made this for the second time last night from your cookery book. It is delicious as are all the other recipes I've made so far from your book.
