French Onion Soup

Published on 27 February 2023
Sweet, savoury and seriously moreish. French onion soup is the retro classic having a resurgence. Heavy on the hands on time but worth the wait once you dip your first Gruyere topped baguette croute into the warming / steaming soup. We’ve added our own twist for something a little different, and love it or hate it, Marmite adds a delicious unami hit.Time and servings

Melt the butter and oil in a large saucepan. Add the onions, bay leaves, thyme and salt then stir well. Cover and sweat the onions for about 45 mins, stirring occasionally, until they are cooked through, soft and beginning to turn light golden.Step 2
Remove the lid and continue cooking for 15 mins until the onions caramelise and turn deep golden, stirring frequently.Step 3

Meanwhile, set the grill to medium. Spread the baguette slices over a wire rack and grill for 1-2 mins on each side until lightly toasted. Sprinkle over the grated gruyere and return to the grill until the cheese is melting and bubbling (see Tip).Step 5
Divide the soup between bowls, top with cheesy toast and sprinkle with remaining thyme to serve.
