What it is

What is a classic tomato sauce?

A classic tomato sauce is the simplest mother sauce to make and the one that rewards good ingredients the most. At its heart it is tomatoes cooked down with a little fat and a few aromatics until they lose their raw edge and turn sweet and cohesive. Escoffier counted tomato among the five French mothers, and the home-kitchen version is something you can build any night from a can.

The reason it is a mother and not just a recipe is its reach. Pull the same base in different directions and it becomes marinara, pizza sauce, or a long-simmered pomodoro. It is the foundation under pasta, baked dishes, and braises, which is why a cook who can make it well rarely needs a jar.

The recipe

What goes in a classic tomato sauce?

28 oz
Tomato
×
2 tbsp
Fat
×
aromatics
Onion, garlic

This sauce is forgiving rather than rigid, but the working ratio is one large can of tomatoes to about two tablespoons of fat and a handful of aromatics. Whole canned tomatoes crushed by hand beat pre-crushed ones, which often taste tinny.

Method

How do you make a classic tomato sauce?

  1. Warm the olive oil over medium heat and soften the onion until translucent, about five minutes.
  2. Add the garlic and cook one minute, until fragrant but not browned.
  3. Crush the tomatoes by hand and add them with their juice. Stir in the salt and a pinch of sugar if needed.
  4. Simmer uncovered for twenty-five to thirty minutes, stirring now and then, until thickened and the raw tomato taste is gone.
  5. Tear in the basil at the end and adjust the salt. Blend for a smooth sauce or leave it rustic.
Turn it into marinara Push the garlic up, drop the onion, and finish with more basil and a glug of olive oil. That brighter, quicker version is marinara, built for weeknight pasta.
Cook's notes

What should you know before making a classic tomato sauce?

History

Where did a classic tomato sauce come from?

Tomato sauce entered the canon of grand sauces when Auguste Escoffier named tomato among the five French mothers in 1903, formalizing a sauce that Italian and American kitchens had long made their own. Fannie Farmer's American cookery of the same era records the home versions that most closely match this one.

Drawn from the public-domain text of Auguste Escoffier, Le Guide Culinaire (1903).

FAQ

Common questions.

How do you make tomato sauce from scratch?

Soften onion and garlic in olive oil, add a can of crushed whole tomatoes, and simmer about thirty minutes until thick and sweet. Season with salt and basil. That is the whole sauce.

What is the difference between tomato sauce and marinara?

A classic tomato sauce often uses onion and a longer simmer for a rounder flavor. Marinara is brighter and faster, leaning on garlic and basil with little or no onion.

Should I use fresh or canned tomatoes?

Canned whole tomatoes are more reliable year round, since they are picked ripe. Use fresh only at peak summer when tomatoes are genuinely good.

Why is my tomato sauce sour?

The tomatoes were sharp. A small pinch of sugar or a knob of butter at the end rounds out the acidity without making the sauce sweet.

How long does homemade tomato sauce keep?

Up to a week in the fridge and three months in the freezer. It freezes especially well, so a double batch is rarely wasted.
