Creamy roast garlic and lemon pasta sauce

  • Author: Emilie Pullar
  • Total Time: 1 hour 15 minutes
  • Yield: 2 - 3 people


A simple creamy pasta sauce packed with flavour. A combination of sweet roast garlic, zingy lemon, pepper and parmesan make this a truly delicious and luscious sauce.


  • Pasta of your choice, I do 150g fresh per person or 100g dried
  • 2 whole heads garlic
  • 2 tbsp olive oil
  • 30g butter, cubed
  • 1/2 tsp pepper
  • 1 cup cream (I used single but use heavy if you want!)
  • 2 - 3 tbsp freshly squeezed lemon juice
  • Zest of a lemon
  • 50g parmesan, finely grated with a microplane or equivalent
  • Extra zest to serve
  • Dried paprika flakes to serve


  1. Preheat your oven to 200 celsius (400f)
  2. Prepare your garlic bulbs. Take off the outer papery layers and cut the top off horizontally. You want to cut off just enough that you expose the tops of the cloves.
  3. Drizzle the top with olive oil then wrap up each one individually in foil and roast in the oven for about 45 mins or until the cloves are soft and starting to caramelise.
  4. When roasted to your liking let them cool and then squeeze all the garlic out. I like to use the back of a spoon on a chopping board to turn it into a smooth paste.
  5. Cook your pasta in a pot of well salted boiling water.
  6. Melt the butter in a frying pan over medium heat.
  7. Let it foam up then add the pepper and stir.
  8. Add the garlic paste and whisk (you don't need to add all of it, I love garlic so add it to taste!)
  9. Add the cream and whisk (lower the heat so it's not boiling, it should be a gentle simmer throughout the process).
  10. Add the lemon juice and zest and whisk again.
  11. Add the parmesan in a few lots, whisking and letting it melt in between each addition.
  12. Let it gently simmer for a couple of mins until it thickens slightly.
  13. Add your cooked pasta straight into the sauce with a 1/4 cup of pasta water and let it bubble away for a minute or so.
  14. My biggest tip is that you want it on the saucier side so add more pasta water if you need to loosen. Pasta soaks up sauce quick so by making it super saucy in the pan by the time you serve it into bowls it will be perfect!
  15. I like to top the pasta with extra lemon zest and some paprika flakes


  • The amount of lemon and garlic is up to you! You might want to add half of both to start but if you like big flavour like me chuck it all in! You can add more lemon juice if you like!
  • If you can't find the dried paprika flakes (I use this brand) then add a sprinkle of chilli flakes or a dusting of smoked paprika powder to the top, or neither is fine!
  • This sauce is probably enough for three portions of pasta, I favour big portions oops. You can always add some extra pasta water to make it go a bit further.
