Method

01

Place a heavy-bottomed saucepan over medium heat and add the extra virgin olive oil. Once the oil is shimmering, add the diced yellow onion and saute until softened and translucent.

7mLook for: Onions are translucent and soft, without brown color
02

Add the smashed garlic cloves to the saucepan. Saute, stirring frequently with a wooden spoon, until the garlic is intensely fragrant and just starting to turn lightly golden.

2mLook for: Garlic is pale goldenFeel: Aromatic and fragrant
03

Carefully crush the canned whole peeled tomatoes by hand one by one over the pot, letting the pieces fall in. Pour in all the remaining tomato juices from the cans.

04

Stir in the whole fresh basil sprigs, fine sea salt, and black pepper. Bring the mixture to a gentle simmer at around 90 degrees Celsius (195 degrees Fahrenheit). Reduce the heat to low, partially cover the saucepan, and let it simmer gently to meld the flavors and thicken.

45mLook for: Oil separates slightly on the surface and sauce has thickened to a rich consistency
05

Remove the saucepan from the heat. Fish out and discard the basil sprigs and garlic cloves if a smoother, milder flavor is desired. For a completely uniform texture, puree the sauce directly in the pot using an immersion blender.

Chef's Notes

  • Crushing whole canned tomatoes by hand provides a superior, rustic texture compared to buying pre-crushed or pureed tomatoes, which often contain firming agents.
  • Leaving the garlic cloves whole and smashed allows you to extract their sweet, mellow flavor without overpowering the sauce. Removing them at the end ensures a perfectly balanced profile.
  • Do not chop the basil before cooking. Simmering whole sprigs infuses the sauce deeply without turning the delicate herb bitter or black from extended heat exposure.
  • This recipe intentionally omits dried herbs like oregano to serve as a pure, versatile canvas. Adjust the seasoning profile later depending on whether you are using it for a delicate fish dish or a robust meat ragu.
