What is Aglio E Olio?
Spaghetti Aglio e Olio, translated as Spaghetti with Garlic and Oil, is a traditional Italian pasta dish that is made by lightly sautéing sliced or minced garlic in olive oil, then tossing with spaghetti. It sometimes has the addition of dried red chili flakes, and I use them in this recipe for an extra kick.

DON'T THROW OUT YOUR PASTA WATER
The secret to the best pasta ever is all in your pasta water.
The salty, starchy pasta water works its magic in a few ways…
- It adds flavour and richness to the sauce
- It thickens the sauce
- It helps the sauce stick to the pasta
Goodbye sauce puddles lying on the bottom of the plate. Hello best pasta ever!
All you need to do is reserve half a mug of pasta water just before you drain your pasta.
Then add your cooked pasta and some of the pasta water to your pasta sauce (start with ¼ cup), and cook for a few minutes, tossing regularly. The sauce will thin out initially, but don’t worry, it will quickly thicken into a delicious creamy texture.
HOW TO MAKE SPAGHETTI WITH GARLIC AND OIL - STEP BY STEP
Bring a large pot of water to boil, add a generous amount of salt to the pot, then add in the pasta. Cook according to packet instructions. Reserve ¼ cup of pasta water, then drain.

When the pasta is almost ready heat oil in a frying pan over low heat, then add garlic and sauté for 1-2 minutes until it just starts to turn golden around the edges. Be careful here - garlic can burn quickly and turn bitter. Add red chilli / pepper flakes and stir for 30 more seconds.


Add the ¼ cup of reserved pasta water, then the spaghetti and cook, stirring regularly, until the liquid has reduced. Remove the frying pan from heat and stir through a good handful of shredded parmesan cheese, tossing through the pasta.


Serve immediately with extra parmesan cheese on top and garnish with chopped parsley and a drizzle of olive oil, if desired.
TOP TIPS
- Use a good quality olive oil - the flavours in this dish are simple and the olive oil really elevates it.
- Use freshly grated parmesan - never the stuff from the can!
- Be careful when sautéing the garlic that you don't burn it as it will then become bitter. Keep the burner on the lowest setting and slowly sauté until the garlic is fragrant and just starting to turn golden around the edges.
- Never throw out your pasta water without reserving a little! Then add your cooked pasta and some of the pasta water to your pasta sauce (start with ¼ cup), and cook for a few minutes, tossing regularly. The sauce will thin out initially, but don’t worry, it will quickly thicken into a delicious creamy texture.
- Serve with extra parmesan and more olive oil drizzled on top, if desired.
- Cooking for one? Simply halve this recipe! It's one of my go-to's when I'm home alone!

Eat this on its own, or add grilled chicken and veg...just make sure you double the recipe, because this is outstanding.

Can you mince the garlic?
Cassie

You can, but as it is one of the only few flavour elements in this dish I think the small pieces help make a lovely bite.

Can you double the recipe? If so, is the water also doubled? It seems like the sauce would be really watery.

Hi Mary - you can definitely double the recipe. I wouldn't recommend doubling the pasta water unless it looks extra dry. The reason for the pasta water is to help everything stick together nicely rather than a sauce sitting on top of the pasta if that makes sense. But really you can't go too wrong - sometimes ive gone a little heavy handed on my pour of water and I just cook it down, add a little more EVOO and its all good. Enjoy 🙂
