onion miso soup edwardian writing

A classic French recipe I’ve adored since the very first time I ate it.

Melting gruyere cheese on toasted bread sitting atop deep and concentrated flavors of beef and onions, with the sweet and herbaceous aroma of thyme… This combination will make any Frenchman or woman drool with delight and impatience! I make French onion soup from time to time whenever there’s wine left from the previous night (it’s a toss between this and beef bourguignon), or have a bag of onions about to go bad in the fridge.

Lately though, I looked for ways to make the soup without using wine and rather with ingredients I always have in my pantry. That’s when I thought of miso paste; sweet, salty and concentrated in earthy flavors, it may just be the right key ingredient to complement beef broth.

Add a little balsamic vinegar to brighten up the flavors and tone down the saltiness and you’ve got yourself a French onion soup pretty close to the real thing.

What you’re looking for when making good French onion soup is a broth that’s savory and concentrated. How you achieve this is by letting the broth simmer for a while so the soup reduces until you are left with a rich, golden brown liquid and plenty of onions to savor spoonful after spoonful.

This is a rustic and hearty dish that pairs well with a simple salad (like this arugula, walnut and blue cheese salad) and a light protein (such as poulet Basquaise).
