A timeless Italian recipe, aglio e olio is made with just 5 ingredients (spaghetti, garlic, extra virgin olive oil, crushed red pepper flakes, and parmesan cheese) in just 20 minutes.

Weekend or weekday, my pasta cravings just never go away! A big bowl of this fuss-free, simple pasta is always exactly what I need. Spaghetti aglio e olio, translates to “garlic and oil spaghetti”. How could you go wrong with that? 

I use thin spaghetti so each piece of pasta is extra-coated in a smooth garlic oil with a touch of heat from red pepper flakes, pops of fresh parsley, and nutty Parmigiano-Reggiano. Truly delicious food does not have to take hours to prepare! From start to finish, you will have a steaming bowl of happiness in less than 20 minutes.

Aglio e Olio Ingredients

  • Thin spaghetti – thin spaghetti is thinner than regular spaghetti and thicker than angel hair. You can use regular spaghetti if you can’t find thin spaghetti. 
  • Garlic – lots of garlic is a main component of classic aglio e olio.
  • Fresh Italian parsley – parsley adds brightness and freshness. 
  • Extra virgin olive oil –  extra virgin olive oil adds flavor and moisture. A high-quality Italian olive oil is the best option, since it’s a predominant flavor in this pasta dish!
  • Parmigiano-Reggiano – I highly recommend splurging on Parmigiano-Reggiano (aged parmesan cheese) for aglio e olio. With only 5 ingredients, high-quality ingredients are especially important! 
  • Crushed red pepper flakes – crushed red pepper flakes are commonly found in aglio e olio. For a little heat, add a dash (of a lot) of red pepper flakes! Don’t like heat? Leave the flakes out!

  • Swap fresh herbs: use fresh basil instead of fresh parsley. 
  • Add sun-dried tomatoes: consider adding sun-dried tomatoes for a touch of sweetness and tanginess. They will add a burst of flavor to the dish! 
  • Add anchovies: finely chop or mash anchovies and sauté them in the garlic oil before combining with the pasta.
