The cheese & onion sandwich is a classic British recipe, but most of the cheese & onion sandwiches on the market contain a lot of cheese (and mayonnaise) but very little onion.
Of the two eponymous ingredients in a cheese & onion sandwich, the onion is easily the healthier. Not to mention it adds an extra zing that makes a simple cheese sandwich into something more interesting.
Whether you’re looking to maximise or minimise the amount of onion in your sandwich, here’s the info you’ll need to find your perfect brand.
Amount of Onion in Cheese & Onion Sandwiches
We surveyed 13 cheese & onion sandwiches on the market. Unfortunately, only 8 state their percentage onion in their ingredients, which means the amount per pack is also otherwise not determinable.
The Tesco cheese & onion sandwich claims 8% yellow onion, which is the highest percentage of onion by far out of the 8 brands that state their amount of onion. This equates to 13.8g of onion per 172g pack, which again is the highest amount of onion per pack by far.
The sandwich with the least onion, both by percentage and amount per pack, is the Morrisons cheese & onion. The percentage is 3%, equating to 4.5g of yellow onion per 150g pack. However, this is again only out of the 8 brands that do state their amount of onion.
Median Amount of Onion
Reduced Fat Sandwiches
Is there more or less onion in a reduced fat cheese & onion sandwich than in a standard one? It depends.
Both Morrisons and Sainsbury’s sell reduced fat versions of their cheese & onion sandwiches alongside the standard version. However, the Morrisons reduced fat version contains more onion (4% or 5.7g) than its standard counterpart (3% or 4.5g), while the Sainsbury’s reduced fat version contains less onion (3.5% or 5.0g) than its standard counterpart (4% or 6.0g).
Types of Onion in Cheese & Onion Sandwiches
Yellow onion is the most versatile and most commonly used onion for cooking. It has a sharp and astringent flavour that turns sweeter when cooked.
Red onion has a milder and sweeter flavour, and loses its bright magenta colour if cooked. For these reasons, it’s often included raw in salads and sandwiches.
Spring onion is milder in flavour and is grown in a warmer climate. Unlike other onions, the green leaves (rather than the bulb) are the main part of the onion that is eaten.
Chives are milder in flavour and their narrow green leaves are used as a garnish or herb.
Although red onion is usually the onion of choice for most sandwiches, the cheese & onion sandwich is an exception. Most cheese & onion sandwiches, including those by Tesco, Asda, Morrisons, Waitrose and Greggs, opt for chopped yellow onion.
A few cheese & onion sandwiches, such as the one by On the Go!, use chopped spring onion, while some include chopped chives. Perhaps most unusually, the Greggs cheese & onion sandwich is famous for enhancing the crunch of its onion with sliced carrot.
