What is passata, exactly? And is it just tomato sauce with a fancy Italian name? I get this question constantly, usually from friends standing in the pasta aisle holding a bottle of each and comparing prices. The two are related – one literally becomes the other in our kitchen every Sunday – but they are absolutely not the same thing.
Here is the simplest way to remember it: passata is an ingredient, tomato sauce is a component that has already been cooked and seasoned. Nonna would shrug and say one is the tomato and the other is the recipe. She was right, as usual.
What is passata?
Passata (passata di pomodoro, or strained tomatoes) is tomatoes and nothing else. Ripe tomatoes are crushed, milled or sieved to remove skins and seeds, briefly heated, and bottled. No salt, no garlic, no herbs, no oil, no sugar. Open a bottle of good passata and it tastes like a summer field smells.
Because it is pure tomato, passata is wonderfully versatile: it becomes sugo on Sundays, pizza sauce on Fridays, the base of braises, soups and casseroles all winter. In our house it also gets drunk straight from a small glass with a pinch of salt, which I am told is a very Italian thing to do.
If you want to make your own, our step-by-step guide to making passata at home covers the whole family production line – crates of Romas, the passata machine clamped to the bench, and a garage full of bottles by sundown.
What is tomato sauce?
Tomato sauce (in the Italian sense – what we call sugo or salsa di pomodoro) starts with passata or fresh tomatoes, then adds the flavour builders: garlic, onion, olive oil, basil, salt, and usually a much longer cook. The sauce that comes from a supermarket jar walks the same path with added sugar, thickeners and preservatives.
So when a recipe says add tomato sauce, it wants something that already tastes like a sauce. When it says passata, it wants clean tomato flavour it can build on.
Passata vs tomato sauce: the key differences
- Ingredients: passata is 100% tomato; tomato sauce is tomato plus seasonings (and in commercial jars, sugar and additives).
- Cooking: passata is only briefly heated before bottling; tomato sauce simmers for hours.
- Flavour: passata is bright, fresh and clean; tomato sauce is deep, savoury and rounded.
- Use: passata is a starting point; tomato sauce is ready to spoon over pasta as-is.
- Consistency: passata is a pourable puree; cooked sauce reduces and thickens.
Can I substitute one for the other?
Sort of, with caveats. If a recipe calls for passata and you only have jarred pasta sauce, you will get a seasoned result that may clash with what you are cooking (plus sugar you did not plan for). If a recipe calls for tomato sauce and you only have passata, congratulations – you are now making sauce from scratch: add olive oil, garlic, basil and salt, and simmer it down for 30 to 45 minutes. That is literally how sugo is born.
What you should never do is confuse Italian passata with American tomato sauce in the ketchup sense – sweet, vinegary and spiced. There is no rescuing a bolognese that got a cup of ketchup in it. Ask me how I know.
Passata in the Australian pantry
Here is the good news for Aussie cooks: you do not need an Italian nonna to get proper passata. Every major supermarket stocks it – look for passata di pomodoro in glass bottles in the pasta aisle rather than the sauce jars, and check the ingredient list says tomatoes only. Italian delis and markets carry local brands made from Australian Roma tomatoes, often at prices that undercut the imported ones.
Of course, the very best passata in Australia is the stuff you bottle yourself. Late-summer crates of Romas from the markets, a passata machine clamped to the bench and a free Saturday will set you up for a year – and yes, that is exactly how our garage ends up looking every March.
Which should you keep in the pantry?
Both, honestly, but passata first. A case of passata in the cupboard is a case of possibilities: it becomes sauce, soup, braising liquid or pizza base in minutes. Every late summer when tomatoes are cheap, we bottle our own – it is easier than you think and the flavour beats anything on a shelf.
Make your own and you will never stand in the pasta aisle comparing labels again. That, and your kitchen will smell like nonna's for a week. There are worse fates.
Passata vs tomato sauce at a glance
- Ingredients: passata is 100 percent tomato; sauce adds garlic, herbs, oil and salt (jars add sugar and additives)
- Cooking: passata is only briefly heated; sauce simmers for hours
- Flavour: passata is bright and fresh; sauce is deep and savoury
- Role: passata is an ingredient to build on; sauce is ready to serve
- Texture: passata is a pourable puree; sauce is reduced and thicker
Common mistakes when substituting
The biggest one is volume. Because sauce is already reduced and seasoned, swapping it one-for-one for passata gives you a dish that is too salty, too sweet and too thick – and it will reduce even further as it cooks. Start with about three-quarters of the quantity and taste as it simmers.
The second mistake is forgetting the garlic and oil. If your passata-based sauce tastes thin or sharp, it is not missing salt – it is missing a slow start: olive oil, gently warmed garlic, and time. Twenty extra minutes of simmering fixes what a spoonful of sugar never will.
The third: storing a half-used bottle of passata with the lid off. Oxidation turns it dull and sour within days. Decant leftovers into a clean jar, add a slick of olive oil on top, lid on tight, fridge – it will comfortably last the week.
Passata vs tomato sauce FAQ
Is passata just blended tomatoes?
Essentially yes – ripe tomatoes milled or sieved to remove skins and seeds, then briefly heated and bottled. Nothing added: no salt, garlic, herbs or oil.
Can I use tomato sauce instead of passata?
You can, but the dish will already taste seasoned and slightly sweet, which can clash with your own seasoning. If you must, choose the plainest sauce available and reduce any added salt in the recipe.
Is passata the same as tomato puree?
Very close. In most of the world passata and tomato puree refer to the same thing: strained, unseasoned tomato. American tomato puree is sometimes slightly more cooked or concentrated, so check the label – the ingredient list should say tomatoes only.
Is passata healthy?
Passata is just tomatoes, so it carries whatever tomatoes carry – including lycopene, which studies suggest becomes more available to the body after brief cooking. No sugar, no preservatives in the homemade version.
What is a substitute for passata?
The closest substitute is tomato puree, followed by plain canned tomatoes blitzed smooth in a blender. In a pinch, tomato paste diluted with water (about one part paste to three parts water) gets you in the neighbourhood – just taste as you go, because it is more concentrated.
What is passata called in Australia?
In Australia it is sold simply as passata or passata di pomodoro – glass bottles of it sit in the pasta aisle of every major supermarket, and Italian delis carry local brands made from Australian Roma tomatoes.
What is passata used for?
Pasta sauces (especially sugo), pizza bases, soups, braises, meatballs, shakshuka, casseroles – anywhere you want clean tomato flavour you control yourself.
