Onions might be in everything but they're still an underrated ingredient. These recipes all make the humble onion the centre of attention. If you love onion recipes (and onions, in general) you're really going to get a kick out of our caramelised onion linguine. We've also got a rich and warming French onion ramen recipe and an easy cheese and onion quiche recipe that'll blow your mind. These dishes aren’t great if you’re allergic to onions – in fact, they might just be deadly – but if you’re a fan of alliums then you’re going to love these rich recipes.
