Low-FODMAP 30-Minute Spaghetti Alla Carbonara; Gluten-free

Print Friendly Version

So simple.  Low-FODMAP Spaghetti Alla Carbonara is food perfection.  This is a meal that whips up in under 30 minutes, but tastes like a gourmet Italian restaurant.

Although there is no cream in traditional spaghetti alla carbonara, the eggs and cheese together make for a creamy and rich sauce.  It is amazing.  Pay attention to the directions to ensure yours tastes as authentic as the Italians 🙂

You can enjoy Spaghetti Carbonara anytime, but in a low-FODMAP version that is also gluten-free!

Although this recipe has not been tested, a single serving should be low-FODMAP based on the ingredients (*using available FODMAP data at time of posting)

Serves: 6-8

Prep time: 10 min

Cook time: 20 min

Total time: 30 min


  • 16 ounces low-FODMAP, gluten-free dry spaghetti
    • I used Barilla GF spaghetti
      • Per their website, 16 ounces of their GF dry spaghetti will yield about 8.7 cups of cooked pasta
      • Ingredients are: corn flour, rice flour, mono and diglycerides
    • One maximum low-FODMAP serve is 1.5 cooked cups, if you use standard gluten-free pasta, based on the Monash app for this ingredient
    • You can also use angel hair or spaghettini, if you prefer.  If you do, just confirm you are within the recommended serving size for each low-FODMAP portion, based on your product 🙂
  • 2 tablespoons garlic infused olive oil, or plain olive oil
    • Infused oils have all the flavor but NOT the FODMAPs! They are not absorbed into the oil base so you are allowed to enjoy this ingredient.  See my low-FODMAP Top 11 Tips and Tricks for more know-how!
  • 6 ounces pancetta or slab bacon, cubed or sliced into small strips
    • Verify your brand has no added onion, or garlic
    • This is not the same as strip bacon
  • 2 large whole eggs and 2 egg yolks, room temperature
  • Just over 1 cup (100g) freshly grated Pecorino Romano or Parmigiano-Reggiano (Parmesan cheese), plus more for serving
    • Check that your cheese brand is low in carbohydrates, this will indicate that it contains few FODMAPs, as the main FODMAP in cheese is typically lactose. Most cheeses are naturally low in FODMAPs.  Pecorino is low-FODMAP in servings of 40g
    • Do not buy pre-grated cheese, the flavor and texture will not work in this recipe
    • Use the smallest/finest pores on your cheese grater to prep your cheese for the sauce.  If you want a coarser grated cheese for the garnish, then adjust to your preference
  • 1/2 tsp freshly ground black pepper, plus to taste
  • Kosher salt, for boiling water and to taste if desired
  • 1 handful fresh Italian (flat) parsley, or regular parsley chopped, for garnish


Rachel’s Notes: You should prepare the sauce while the pasta is cooking to ensure that the spaghetti will be hot when the sauce is finished.  The heat of the pasta will ‘cook’ the eggs in the sauce. See below!  I suggest reading through the recipe once first so you can follow the steps easily.  You don’t want to end up with ‘scrambled egg sauce’ 🙂

  • Bring a large pot of salted water to a boil. Add your pasta and cook for 10-11 minutes until cooked but slightly firm (otherwise known as al-dente)
    • Adjust this time based on your pasta brand (gluten-free will get mushy so do NOT overcook)
    • You should use about 4 quarts (3.7 liters) of water and about 1 tablespoon of kosher salt.  Start with cold water and do NOT add oil to the water and pasta for best results
    • Do not break up your pasta strands if you want this to look authentic.  However, be aware that GF pasta will still break a fair amount when you are tossing it
  • In a small bowl, beat the eggs and egg yolks with Pecorino or Parmesan together well, then add the 1/2 teaspoon of black pepper and whisk again. Set aside for later
    • It should be like a creamy sauce
  • Once your pasta is about halfway through cooking, heat the infused oil in a deep skillet over medium heat (I prefer an 11 inch cast iron skillet for this)
  • Add the pancetta or slab bacon and sauté until the bacon is crisp (about 3 minutes)
    • If you have a lot of grease in the pan, then gently discard it, per your preference
  • Remove 1/2 cup of the pasta water for later, then drain the pasta
  • Remove pan from heat and turn off your burner. Add the drained pasta to the pan and toss for 2 minutes to coat the noodles in the residual fat.  Allow the pasta to cool down slightly in the pan (you want the noodles to be less than 145F to not scramble the eggs.  My cast iron pan took a couple minutes since it retains a lot of heat)
  • Gently, a little at a time, pour the egg/cheese mixture into the pasta, stirring constantly using tongs, until the eggs thicken, but do not scramble (this is done off the heat to limit the eggs from overcooking)
  • Thin out the sauce with the reserved pasta water, if you like, until it reaches your desired consistency (optional)
  • Season the carbonara with several turns of freshly ground black pepper.  It likely will not need salt as the cheese and pancetta are already quite salty
  • Serve the low-FODMAP Spaghetti Alla Carbonara garnished with the chopped parsley and additional Pecorino/Parmesan to taste!

    1. Thanks for the question, however we do not think turkey bacon would result in the same amount of fat or flavor. As the recipe mentions, strip bacon is not a good substitute for the pancetta either. Traditional alla carbonara is made with pork products, sorry. However, if you want another pasta option, check out our low-FODMAP Fettucini with Artichokes and Lemon. Good luck!

  1. Amazing!

    I was amazed by how delicious and easy this was. Thank you also for the video, it really helped me. Great recipe!!

    1. Hi Tammy,
      Thanks for your question!
      For starters, we would be concerned that vegan parmesan is low-FODMAP. We also don’t think it would cook in the recipe the same as real cheese. We suggest you consider another recipe on our site that is dairy-free instead (we have many!) for the best experience. Good luck 🙂

      You can! But may need to experiment. There are several high quality plant parmesans on the market, I’d recommend adding a touch of porcini powder for the tartness.. As with all cheese, try to buy in block when possible, pre-shredded covers the shreds in various ‘dusts’ to keep them from sticking together that will make it melt much worse or clump up and not mix in.

      Cooking is all about experimenting, don’t let the ingredients dissuade you from trying the meal.

      1. Thanks for your comments Gnar, but we are still very concerned about this misleading our readers about FODMAP content. If a plant based product for cheese is made from soy, almond or cashew then it is may not be tolerated.
        Since our focus is on Low-FODMAP Recipes, we want to keep that in the theme!
