The Golden Steps to Onion Soup Glory
Ready to cook? Here's the lowdown:
- Caramelize those onions. Melt the butter and oil in a big pot. Chuck in the onions, sugar, thyme, salt, and pepper. Cook it low and slow over medium-low heat. Stir now and then. You want them a deep golden brown. This will take around 30- 45 minutes . Don't rush it.
- Deglaze if you dare. If you're using wine, pour in the 1/2 cup and scrape up those yummy browned bits. Cook until nearly dry.
- Simmer, simmer. Add the 6 cups of beef broth , Worcestershire sauce , and the bay leaf . Bring to a simmer, then turn it down low. Let it bubble gently for at least 30 minutes . Even better, an hour. This lets the flavors get to know each other.
- Toast the bread. While the soup simmers, preheat the oven to 350° F ( 175° C) . Toast your baguette slices for a few minutes per side. Just until lightly crisp.
- Assemble the dream. Ladle the soup into oven-safe bowls. Pop a toasted baguette on top. Pile on the Gruyère cheese . Don't be shy.
- Broil 'til bubbly. Stick the bowls on a baking sheet and broil until the cheese is melted, bubbly, and golden brown. Watch like a hawk. This only takes a minute or two.

Frequently Asked Questions
Why does my onion soup recipe taste bitter? Are my onions the problem?
Bitterness in onion soup usually comes from the onions being burned during caramelization. Make sure to cook them over medium-low heat, stirring frequently, and watch them like a hawk. If they start to burn, reduce the heat or add a splash of water to deglaze the pan, channeling your inner Gordon Ramsay and preventing any kitchen nightmares!
Can I make onion soup vegetarian, and what's a good substitute for the beef broth?
Absolutely! Swapping out the beef broth is simple. Use a high-quality vegetable broth instead, but consider adding a splash of balsamic vinegar or a dash of soy sauce to give it a bit of that "umami" depth you'd get from beef. Think of it as a secret weapon in your culinary arsenal; even Mary Berry would approve!
What's the best cheese to use for French onion soup, and can I use something else if I don't have it?
Gruyère is the classic choice because it melts beautifully and has a nutty flavour that complements the soup perfectly. However, if you're fresh out, Swiss or even provolone can work in a pinch. Just remember, using a good quality cheese is like choosing a fine wine; it elevates the whole experience, as Delia Smith herself would tell you.
How long does onion soup last in the fridge, and how do I reheat it?
Onion soup will generally keep well in the fridge for 3-4 days. Store it in an airtight container. Reheat gently on the stovetop over medium heat until warmed through. I would recommend adding croutons and cheese only just before serving and not reheating the croutons themselves. You can also microwave it, but stovetop is better for a more even and gentle reheat.
My onion soup is too salty! How can I fix it?
Oops! Salty soup is a common kitchen mishap. Adding a pinch of sugar can help to balance the saltiness. You can also add a small amount of acid, such as lemon juice or apple cider vinegar. If it's really salty, you might need to add a bit more water or unsalted broth to dilute it. Think of it as a rescue mission for your taste buds!
Is there a quicker version of this onion soup recipe? All that caramelizing feels like hard work!
Okay, let's be realistic, proper caramelization does take time and TLC. If you're strapped for time, you can cheat a little by adding a teaspoon of balsamic vinegar during the onion cooking process. It will help to bring out the sweetness and deepen the colour faster. However, remember that the flavour won't be quite as complex as the slow-cooked version. Still, it's a decent shortcut when you need that onion soup fix and the clock's ticking!
