Ingredients & Equipment
Alright, here's the lowdown on what you need. I’ll give you my tips for snagging the best stuff.
Main Ingredients
Let's start with the stars of the show. Forget cutting corners. Good ingredients = fantastic soup.
- Unsalted Butter: 3 tablespoons (45 ml) . Real butter, none of that spread nonsense.
- Olive Oil: 2 tablespoons (30 ml) . Extra virgin is best, for a richer flavour.
- Yellow Onions: 3 pounds (1.4 kg) , thinly sliced. This is KEY. Quality is everything. Onions should be firm and smell, well, oniony. Avoid soft or sprouty ones.
- Granulated Sugar: 1 teaspoon (5 ml) . Just a touch to help the onions caramelize.
- Kosher Salt: 1/2 teaspoon (2.5 ml) , plus more to taste. Salt is your friend.
- Black Pepper: 1/4 teaspoon (1.25 ml) , plus more to taste. Freshly ground is best.
- Garlic: 2 cloves , minced. Adds a bit of punch.
- Dry Sherry or White Wine: 1/4 cup (60 ml) . This is optional but gives that authentic flavour! Sherry is my personal fave for this classic French onion soup .
- Beef Broth: 8 cups (1.9 liters) , low sodium. Now listen up. Good broth is essential. If you can, make your own. Seriously. But if not, go for the best quality store-bought stuff you can find.
- Fresh Thyme: 4 sprigs . Adds an earthy, aromatic note.
- Bay Leaf: 1 . A classic flavour enhancer.
- Baguette: 1 , sliced into 1-inch rounds. Go for a crusty one.
- Olive Oil: 2 tablespoons (30 ml) for the croutons.
- Gruyère Cheese: 6 ounces (170 g) , shredded. Gruyère is the classic choice for that bubbly cheesy top. Don't skimp. It needs to be firm and smell slightly nutty.
Seasoning Notes
Let's talk about getting that flavour bangin'.
- Essential Spice Combinations: Thyme and bay leaf. A classic combo for a reason.
- Flavor Enhancers and Aromatics: Garlic and Sherry. They both add depth to the delicious soup recipes . Don't skip them.
- Quick Substitution Options: No sherry? Dry white wine works in a pinch. Also try balsamic, not a lot, but will do the trick.
Equipment Needed
Right, here's what you'll need from the kitchen. Simple but vital.
- Dutch Oven or Heavy-Bottomed Pot: This is essential for even heating and caramelizing those onions.
- Baking Sheet: For toasting those baguette slices into croutons.
- Oven-Safe Bowls or Ramekins: For the final broiling. If you don't have ramekins, don't panic. Oven proof bowls will work just fine.
- Alternatives: Don't have a Dutch oven? A large, heavy-bottomed stockpot will do. No baking sheet? Use a frying pan to make the croutons.

Frequently Asked Questions
Why does my onion soup taste bitter, and how can I avoid it?
Bitterness in onion soup usually comes from rushing the caramelization process. You need to cook those onions low and slow, like you're brewing a proper cuppa. Patience is key; aim for a deep golden brown colour and a sweet, almost jammy flavour. If you accidentally burn the onions, unfortunately, you'll have to start again, mate!
Can I make this onion soup recipe ahead of time?
Absolutely! In fact, the flavour often improves if you make the soup base (before adding the croutons and cheese) a day or two in advance. Store it in an airtight container in the fridge. When you're ready to serve, simply reheat the soup and proceed with the croutons and cheese topping. Just don't assemble it all at once, or you'll end up with soggy bread!
What's the best cheese to use for French Onion Soup? Can I use something other than Gruyère?
Gruyère is the classic choice for a reason – it melts beautifully and has a nutty, slightly sweet flavour that complements the soup perfectly. However, if you're in a pinch or just fancy a change, you can use Comté, Emmental, or even a good quality Swiss cheese. Avoid strongly flavored cheeses like cheddar, as they can overpower the delicate onion flavour, innit?
My onion soup tastes a bit bland. What can I do to boost the flavour?
If your onion soup is lacking oomph, don't fret! First, make sure you've seasoned generously with salt and pepper. A splash of Worcestershire sauce or a dash of balsamic vinegar can also add depth. For a richer flavour, try using homemade beef stock or adding a knob of butter at the end. Taste and adjust as you go until it sings!
How do I store leftover onion soup, and how long will it last?
Leftover onion soup, without the croutons and cheese, will keep in an airtight container in the fridge for up to 3-4 days. It also freezes well for up to 2-3 months. Thaw it in the fridge overnight before reheating. If you have leftover soup with the croutons and cheese, it's best to eat it right away, as the bread will become soggy, like a soggy bottom on a bake-off challenge.
Can I make a vegetarian version of this onion soup recipe?
You bet your sweet bippy you can! Simply swap out the beef broth for a good quality vegetable broth. To maintain the richness, consider using a mix of mushroom and vegetable broth. You can also use vegan butter for cooking the onions and top the soup with vegan cheese or a sprinkle of nutritional yeast for a cheesy flavour. Cracking stuff!
