Agathé Pâtisserie’s Recipe For Epic French Onion Soup

Agathé Pâtisserie is a South Melbourne Market institution, which, if you’re on a diet, you have to walk past with your eyes closed. The reason being they do some of the best and most authentic croissants going around. And nothing breaks a diet like a buttery, flaky croissant (or ten).

But founder and head baker Agathe Kerr also makes a mean onion soup, and she was kind enough to share her not-so-secret recipe with us. The trick? Getting the onions right. In France they usually make this recipe with brown onions, which gives the dish a slightly acidic taste. Here in Aus, we generally go for a sweet purple onion instead. Either way, it’s a classic winter warmer, and goes pretty well with a cheesy grilled baguette and a big glass of red.

Here goes, Melbourne. Our ultimate French Onion Soup recipe.


  • 4 Spanish onions (or brown onions if you want to be legit)
  • 2 garlic cloves
  • 50g butter
  • 2 tablespoons of olive oil
  • 1-litre of chicken stock
  • 250ml of dry white wine
  • 500ml of warm water
  • 1 full tablespoon of flour
  • 6 slices of baguette
  • Gruyere cheese (or cheddar if you prefer)
  • Salt
  • Pepper


First, chuck Amelie on the tellie and pour yourself a hefty glass of good Provencal red. Step 1, accomplished.

Next, peel and cut the onions into thin slices. Peel the garlic cloves and crush them. Melt the butter with the oil and add the onions, stir until soft, then add the garlic too.

Chuck in the flour, chicken stock, water and wine. Bring to the boil and cover. Simmer that for about 30 minute, or as long as it takes Amelie to change a stranger’s life in a whimsical yet heart-wrenching way. Stir the soup occasionally or it’ll catch on the bottom.

Taste as you go. The longer you leave it to simmer, the richer the flavour is going to get. Add salt and pepper to taste.

Last step, cut the baguette into rough discs and cover with grated cheese. Grill for a couple of minutes until golden and bubbling. Serve on top of the soup (with a tiny French flag, if you have one).

Bon appetite!

In case you missed it, Agathé Pâtisserie opened another store this year, tucked into the Royal Arcade. Just follow the smell of croissants.
