French onion soup is usually SO labour intensive. You have to laboriously stand over the stove, dutifully scrape up all those delicious bits of flavour from the bottom of the pan as you slowly but surely caramelize the onions, and then there’s all the stirring. Who has time for that? Well, we have good news, fair-weather chefs, those days are over! Get ready to welcome in a new era of easy, cheesy, broth-soaked-bready goodness. The hardest part is chopping the onions, but that’s what your food processor is for.
