Pasta sauce: what's actually in it?

Jarred pasta sauce is not one thing. Tomato sauces are mostly tomato plus oil, sugar and herbs; pestos are mostly oil, basil and cheese with surprisingly little olive oil; cream sauces start with water and cream, not milk; and “cheese and herbs” sauces can be built on wheat flour and dairy blend rather than tomato at all. This page separates sauces by type, shows the list as printed, and does not give a health score.

Re-audit 5 November 2026: 2 products added (Prego Carbonara Mushroom from a FairPrice SG ingredient section; Rummo Pesto alla Calabrese from EU/UK retailer listings that agree, flagged as non-SG), taking panelled products from 15 to 17. Mutti Rosso/Verde/Arancione pestos at Little Farms still have no complete verbatim list retrievable online — Mutti Rosso's Little Farms page shows only the tail of its list, so it stays seen-but-not-verified. Rummo Sugo Al Basilico / All'Arrabbiata / Ragu' Alla Bolognese and Rosso Gargano sauces are listed at Little Farms with no lists retrieved. This page is still not 100% complete: SG packs for Prego Traditional/Mushroom, Dolmio, Ragu and Leggo's remain unverified, and Giant/Sheng Siong/Cold Storage/Donki ranges still need an in-store check.

* Bertolli Garlic Alfredo lists garlic puree with high fructose corn syrup as a sub-ingredient — see panel. Prices are deliberately not shown.

Tomato-based sauces

Prego Traditional Tomato (Traditional Italian Tomato Sauce)

Pack size: 680g · Made in: USA (as printed)

Ingredients: Tomato Puree (Water, Tomato Paste), Diced Tomatoes In Tomato Juice, Sugar, Canola Oil, Contains Less Than 1% Of: Salt, Dehydrated Onions, Spices, Citric Acid, Dehydrated Garlic, Onion Extract, Garlic Extract

US retail / Open Food Facts listing for Prego Original. FairPrice Singapore lists “Prego Pasta Sauce – Traditional Tomato” 680g and 350g; the SG pack list was not separately retrieved, so this panel is flagged as a US listing for the same product name, not an SG pack transcription. Added sugar: sugar

Prego Mushroom

Pack size: 680g · Made in: USA (as printed)

Ingredients: Tomato Puree (Water, Tomato Paste), Diced Tomatoes In Tomato Juice, Mushrooms, Sugar, Contains Less Than 1% Of: Salt, Canola Oil, Spices, Citric Acid, Onion Extract, Garlic Extract

US retail listing. Note: a different Spoonful listing for a mushroom variant includes beef — that appears to be a different (meat) variant, not this vegetarian mushroom sauce. Check the jar: “mushroom” alone does not guarantee meat-free. Added sugar: sugar

Classico Tomato & Basil

Pack size: 680g · Made in: USA (as printed)

Ingredients: Tomato Puree (Water, Tomato Paste), Diced Tomatoes In Juice (Tomatoes, Tomato Juice, Citric Acid, Calcium Chloride), Contains Less Than 2% Of: Onions, Salt, Basil, Olive Oil, Garlic, Spices, Natural Flavor

Open Food Facts / US retail listing. The notable point is what is absent: no sugar in this list, unlike Classico Traditional Sweet Basil below. No sugar in list

Classico Traditional Sweet Basil

Pack size: 680g · Made in: USA (as printed)

Ingredients: Tomato Puree (Water, Tomato Paste), Diced Tomatoes (Tomatoes, Tomato Juice, Citric Acid, Calcium Chloride), Sugar, Contains 2% Or Less Of: Onions, Salt, Basil, Olive Oil, Spices, Garlic, Granulated Onion, Granulated Garlic, Soybean Oil

US retail listing. Same brand family as Tomato & Basil, different recipe — the word “Sweet” in the name matches the added sugar. Added sugar: sugar

Tomato-cream / vodka sauce

Classico Vodka Sauce

Pack size: 680g · Made in: USA (as printed)

Ingredients: Tomato Puree (Water, Tomato Paste), Diced Tomatoes In Juice (Tomatoes, Tomato Juice, Citric Acid, Calcium Chloride), Cream (From Milk), Water, Vodka, Contains Less Than 2% Of: Parmesan Cheese (Cultured Part-Skim Milk, Salt, Enzymes), Milk, Sugar, Salt, Onions, Olive Oil, Basil, Garlic, Xanthan Gum, Lactic Acid, Spices, Butter (Cream, Salt), Sodium Phosphates, Cheese Cultures, Enzymes

US retail listing. Vodka is the fifth ingredient, before the <2% group — it is a real ingredient here, not just a name. The alcohol itself mostly cooks off in use; the jar still lists it. Allergen: milk Added sugar: sugar (<2%)

Classico Di Liguria Tomato Alfredo

Pack size: 425g · Made in: USA (as printed)

Ingredients: Tomato Puree, Water, Skim Milk, Cream, Romano Cheese (From Cow's Milk), Parmesan Cheese, Salt, Soybean Oil, Dehydrated Garlic, Dehydrated Onion, Basil, Xanthan Gum, Modified Gum Arabic, Lactic Acid, Olive Oil, Black Pepper, Butter, Sodium Phosphate

US retail listing. Filed here, not under plain tomato, because milk/cream/cheese come before the herbs — it is a tomato-cream hybrid. Allergen: milk

Cream / cheese sauces

Prego Pasta Sauce — Cheese and Herbs (FairPrice)

Pack size: 300g · Made in: USA (as printed)

Ingredients: Vegetable Oil, Wheat Flour, Dairy Blend (Whey Solids Milk), Sodium Caseinate (Contains Milk, Soya Bean), Cheddar Cheese [Pasteurised Milk, Cultures, Enzymes (Rennet), Cellulose, Sorbic Acid], Salt, Onions, Stabilisers, Garlic, Eggs, Flavourings (Soya Bean, Wheat Source), Cream (Contains Milk, Soya Bean), Herbs, Sugar, Yeast Extract, Pepper, Disodium Inosinate, Disodium Guanylate

FairPrice Singapore ingredient section — the only FairPrice-verified panel on this page. No tomato in the list at all. Allergens: milk, soya, wheat, egg Added sugar: sugar

Prego Roasted Garlic & Parmesan Cheese

Pack size: 680g · Made in: USA (as printed)

Ingredients: Tomato Puree (Water, Tomato Paste), Onions, Diced Tomatoes In Tomato Juice, Sugar, Parmesan Cheese (Part Skim Milk, Cultures, Salt, Enzymes), Contains Less Than 1% Of: Salt, Dehydrated Roasted Garlic, Parmesan Cheese Paste (Granular And Parmesan Cheese (Milk, Cultures, Salt, Enzymes), Water, Salt, Lactic Acid, Citric Acid), Citric Acid, Flavoring, Spices

US retail listing. Parmesan appears twice — as cheese and as cheese paste — which is why the list looks longer than a plain tomato sauce. Allergen: milk Added sugar: sugar

Bertolli d'Italia Alfredo Sauce (brand official)

Pack size: 425g · Made in: Italy (as printed)

Ingredients: Water, Cream, Butter, Parmigiano Reggiano P.D.O. Cheese (Cow's Milk, Sea Salt, Rennet), Vegetable Oil (Sunflower And/Or Soybean And/Or Canola Oil), Modified Food Starch, Pecorino Romano P.D.O.

Bertolli official site. Water first, cream second — the standard alfredo-jar structure. Allergens: milk, egg

Bertolli Garlic Alfredo with Aged Parmesan Cheese (brand official)

Contains: Egg, Milk

Bertolli official site. The only alfredo panelled here with a sweetener in a sub-ingredient (high fructose corn syrup inside garlic puree) and with cooking wine. Allergens: milk, egg

Pesto — green and red

Barilla Pesto alla Genovese

Pack size: 190g · Made in: Italy (as printed)

Ingredients (Open Food Facts, EU listing): Sunflower seed oil, basil 30%, cashews, parmigiano cheese reggiano PDO 5% (milk), corn fiber, whey powder, salt, milk protein, extra virgin olive oil, sugar, basil extract, natural aromas (milk), acidity corrector: lactic acid. Allergens: Milk, Nuts

EU listing; a second EU listing gives extra virgin olive oil at 1% and a Grana Padano/Pecorino variant — pesto recipes vary by market, so the SG jar must be checked. The consistent points across listings: sunflower oil first, basil 30%, cashews before cheese, olive oil small. Allergens: milk, nuts

Academia Barilla Pesto Alla Genovese (for comparison — same family, different jar)

Pack size: 190g · Made in: Italy (as printed)

Ingredients: Fresh basil, extra virgin olive oil, sunflower seed oil, cashews, pine nuts, parmigiano reggiano PDO cheese (milk, salt, rennet), milk powder, salt, garlic, wine vinegar, fructose, lactic acid (to preserve freshness), citric acid. Allergens: Milk, Nuts

USDA-derived listing. Unlike the EU Barilla jar above, this one starts with basil and lists extra virgin olive oil second — proof that “Barilla pesto” is not one recipe worldwide. Do not merge these two panels. Allergens: milk, nuts

Rummo Pesto alla Genovese (Little Farms)

Pack size: 190g · Made in: Italy (as printed)

Ingredients: Italian Basil 32%, Sunflower Oil, Potato Flakes, Glucose Syrup, Cashew Nuts, Grana Padano Cheese (Milk, Salt, Rennet, contains Egg Lysozyme) 5%, Pecorino Romano Cheese (Ewe's Milk, Salt, Rennet) 4.5%, Extra Virgin Olive Oil 2%, Pine Nuts, Salt, Natural Basil Flavouring, Garlic 0.3%, Acidity Regulator: E270, Antioxidant: E300

Retail listing for the same 185g/190g jar sold at Little Farms Singapore. Glucose syrup is the fourth ingredient — a sweetener, even though the jar is savoury. Allergens: milk, egg, nuts

Rummo Pesto Rosso (Little Farms)

Pack size: 190g · Made in: Italy (as printed)

Ingredients: Tomato Paste 23%, Sunflower Seeds Oil 20%, Water, Dried Tomatoes 9%, Basil 6%, Ricotta Cheese 6%, Cashews, Extra Virgin Olive Oil 3%, Pecorino Romano PDO Goat's Cheese 2%, Pine Nuts 1%, Garlic, Salt, Sugar, Natural Basil Flavouring, Acid: Lactic Acid

Little Farms product page. Red pesto is a tomato pesto, not a green pesto with tomato added as an afterthought — tomato paste is first. Note “Pecorino Romano PDO Goat's Cheese” is as printed on the Little Farms page (Pecorino Romano is normally sheep's milk; the page wording is quoted, not corrected). Allergens: milk, nuts Added sugar: sugar

Cream / cheese sauces — re-audit addition

Prego Pasta Sauce — Carbonara Mushroom (FairPrice Singapore)

Pack size: not stated · Made in: USA (as printed)

Ingredients: Creamer [Glucose Syrup, Hydrogenated Vegetable Fat, Emulsifiers, Stabilisers, E551, E160A], Mushrooms, E1442, Wheat Flour, Flavourings, Substances (Contains Milk, Gluten), Salt, Cream (Contains Milk), Sugar, Yeast Extract, Spice, E621, Egg, E415, E330, Herbs, E270, Lemon Juice

FairPrice Singapore ingredient section, quoted as printed — including the odd “Flavourings, Substances” wording, which looks like a retailer-listing transcription quirk; verify on the SG jar before publishing. Note this SG carbonara is built on a non-dairy creamer (glucose syrup + hydrogenated vegetable fat), not on the US Prego Carbonara list (water, cream, butter, parmesan, cheddar, bacon) — the two are different recipes for the same product name, so the US list is not used here. Allergens: milk, gluten, egg Added sugar: sugar

Pesto — re-audit addition

Rummo Pesto alla Calabrese (Little Farms)

Pack size: 190g · Made in: Italy (as printed)

Ingredients (EU/UK retailer listings, agreeing): Water, Olive Oil, Ricotta Romana PDO Cheese (Ewe's Whey, Salt) 15.4%, Red Pepper Concentrate 14%, Dextrose, Onion, Double Concentrated Tomato, Pecorino Romano PDO Cheese 2.2% (Ewe's Milk, Salt, Rennet), Maize Starch, Acidity Regulator: E270, Whey Protein, Sugar, Salt, Chilli Powder, Oregano

Retailer listings for the same 190g jar sold at Little Farms Singapore (Coop CH, Melbury & Appleton UK and others agree on the list, apart from onion at 5.4% in one listing). Not an SG pack transcription — verify on the SG jar before publishing. Dextrose and sugar are both in the list. Allergens: milk, egg (lysozyme in some listings — check pack) Added sugar: dextrose, sugar

Nutrition — what the numbers say

How to read this table. Figures are per 100 g (or per 100 ml for beer) only where the source gives per-100 figures. Where a source gives per-serving figures only, the row is quoted exactly as printed and the Basis column says “per serving, not per 100 g/ml” — those rows are not converted to per-100 and must not be compared gram-for-gram with per-100 rows. “Not stated” means the source retrieved did not give that column; it is not estimated, borrowed from another variant, or copied across flavours. Salt = sodium × 2.5, so the Sodium column shows sodium as printed with the salt equivalent in brackets. Sodium is not salt, and salt is not sodium.

Most Singapore packs list total sugars, not added sugars. A total-sugars figure is therefore not labelled “added sugar” here; the ingredient list on the page remains the evidence for whether sugar (or sucrose, glucose syrup, cane sugar) was added. No Nutri-Grade is assigned here and no health score, ranking or “best/worst” verdict is given — the numbers below are observations only, and the highest/lowest figures named in the text are just that: the highest and lowest numbers observed in this table.

Sauces are as sold, per 100 g. Where a source prints salt rather than sodium, sodium is calculated as salt ÷ 2.5 and flagged as calculated — the printed salt figure is the evidence. US/EU listings are flagged as such; they are not presented as Singapore pack panels. Note the Classico Tomato & Basil energy conflict below, shown rather than resolved.

Sugar/sodium observations (numbers only): total sugars in this table range from 1.6 g per 100 g (Academia Barilla pesto) to 8 g per 100 g (Classico Traditional Sweet Basil); sodium ranges from 328 mg per 100 g (Classico Tomato & Basil, USDA-derived figure) to 1,468 mg per 100 g (Academia Barilla pesto). Total sugars here include both tomato/basil sugars and added sugar where the ingredient list adds it — the ingredient list, not this column, is the evidence for added sugar.

How to read a pasta-sauce label — the jargon, in plain English

Tomato puree vs tomato paste vs diced tomatoes
Puree is sieved cooked tomato; paste is concentrated puree; diced tomatoes are pieces in juice. A list starting “tomato puree (water, tomato paste)” is reconstituted from paste, not fresh-crushed tomatoes — normal for jars, but not the same as “tomatoes” alone.
Pesto alla Genovese
The Genoa-style green pesto: basil, oil, cheese, nuts, garlic, salt. Jarred versions bulk it with sunflower oil, cashews and potato/corn fibre — the traditional pine-nut-and-olive-oil version is the exception, not the rule, on supermarket shelves.
Alfredo
A cream-and-cheese sauce. Jarred alfredo starts with water and cream, thickened with modified starch and egg yolk, and flavoured with Parmesan/Romano. It is not just melted cheese.
Vodka sauce
Tomato sauce with cream, cheese and a splash of vodka. The vodka is listed as an ingredient; it is not a flavouring alone.
Arrabbiata
“Angry” — chilli-hot tomato sauce. The heat comes from chilli, not from a separate sauce base.
Ragù / Bolognese sauce (jar)
A meat-based sauce in Italy; many SG jars labelled “Bolognese” are tomato sauces meant to be served with mince, not sauces containing meat. Check whether meat is actually in the list (see the Dolmio note in research notes).
Modified food/corn starch, xanthan gum
Thickeners/stabilisers that stop the sauce separating and give it body. Their presence marks a formulated jar sauce, not a defect.
Citric acid / calcium chloride
Acidity regulator and firming agent for diced tomatoes. Not preservatives in the usual sense, but they are why diced tomatoes keep their shape in the jar.
