In October 2020, we pitted big-brand tomato bolognese pasta sauces from Dolmio and Loyd Grossman against cheaper supermarket alternatives, from the likes of Aldi, Asda and Tesco.
Just one pasta sauce impressed enough to be named a Best Buy, and the favoured sauce wasn't one of the branded options.
A branded sauce wasn't far behind, but our top pick will both taste great and make pasta night significantly cheaper, as it's less than half the price.
One supermarket own-brand might disappoint loyal shoppers - its pasta sauce was considered too sharp and lacking balanced flavour, earning it the lowest score overall.

None of the pasta sauces we tested are particularly high in salt, fat or sugar, although some have slightly more salt or sugar than others. They won't push you into the red, but it's worth knowing that more sugar/salt doesn't always make for a tastier sauce.
While none of the sauces are high in salt, the M&S sauce has more than double the amount of salt of the Co-op and Waitrose versions per 100g.
Per recommended portion, the M&S sauce contains a quarter of the maximum daily recommended amount for adults.
Much of the sugar in tomato pasta sauce comes from the tomatoes, but some sauces do have more added sugar in them than others.
None of the sauces are high in sugar, so you don’t need to worry about this adding to your sugar intake for the day. The Waitrose and Co-op sauces contain less than 5g of sugar per 100g, which means they’re low in sugar. The others are medium.
All sauces on test are low or medium in fat and all are low in saturated fat. Adding mince to make bolognese will increase the fat content, but you can opt for a lower-fat beef or lamb mince.
If you want an even lower-fat option, use turkey or a soy mince. Or you can try a vegetable bolognese, using ingredients such as cauliflower, carrots and mushrooms.

All of the pasta sauces we tested are suitable for vegetarians. The sauces from Aldi, Co-op, Morrisons, Sainsbury’s, Tesco and Waitrose are vegan.
Some sauces aren’t vegan due to the manufacturing or supply chain process. These include the Asda, Loyd Grossman and the M&S sauces.
Dolmio and Seeds of Change sauces aren’t officially certified for vegans, but you can find the ingredients on the pack and decide if you want to include them as part of a vegan diet.
Glass jars can usually go in your household recycling bin. Make sure to give the jar a quick rinse and put the lid back on to reduce the chance of it getting lost during the sorting process.
You can also sterilise jars and reuse them for storing other foods.
We chose a selection of ready-made tomato pasta sauces deemed suitable for making bolognese - whether you like just the sauce, or to add your own veg, plant-based proteins or meat to the mix.
The pasta sauces were blind-tasted by a large panel of consumers who regularly buy and consume tomato pasta sauce.
The make-up of the panel broadly represents the demographic profile of adults in the UK.
Each tomato pasta sauce was assessed by 63 people. We served the pasta sauce alongside Napolina fusilli pasta.
The panellists rated the taste, texture, aroma and appearance of each product and told us what they liked and disliked about each one.
The taste test was blind, so the panellists didn’t know which brand they were trying. The order they sampled the tomato pasta sauce in was fully rotated to avoid any bias.
Each panellist had a private booth so they couldn’t discuss what they were tasting or be influenced by others.
The overall score is based on:
These weightings are based on consumer rankings of the importance of different tomato pasta sauce attributes.
