Laziest French Onion Soup Ingredients
• • This recipe is all about smart shortcuts to achieve that classic, comforting flavor.
For the Soup Base
- Yellow Onions – About 2 pounds, thinly sliced. These are the sweet heart of your soup!
- Olive Oil or Butter – About 2 tablespoons; a mix of both adds depth. This is what we’ll use to coax those sweet flavors out of the onions.
- Beef Broth – 8 cups; use a good quality store-bought or homemade beef broth for the deepest flavor. Chicken broth is a fine substitute if that’s what you have.
- Dried Thyme – 1 teaspoon, or 2 sprigs of fresh thyme. This classic herb adds a lovely aroma and subtle earthiness.
- Bay Leaf – 1. It coaxes out even more savory notes from the broth as it simmers.
- Salt and Black Pepper – To taste. Essential for bringing out all the other flavors!
For the Cheesy Topping
- French Baguette – About half a baguette, sliced about 1/2-inch thick. A sturdy bread is best to hold up to the soup.
- Gruyère Cheese – 1 to 1.5 cups, shredded or thinly sliced. The king of French onion soup cheese; it melts beautifully and has a nutty flavor. You can also use a mix including mozzarella or Swiss for variety.
How to Make the Laziest French Onion Soup
- Caramelize Onions: In a large pot, toss your thinly sliced onions with olive oil or butter. Cover and cook on low heat for about 30 minutes, stirring only occasionally, until they’re beautifully golden brown.
- Simmer Soup Base: Pour in your beef broth, add thyme and bay leaf. Season with salt and pepper. Bring to a gentle simmer for about 15 minutes to let the flavors deepen.
- Toast Bread: While your soup simmers, toast thick slices of baguette until they are golden and nicely crisp on the outside.
- Assemble & Broil: Ladle the hot soup into oven-safe bowls. Top each with a toasted baguette slice, then shower generously with cheese until fully covered.
- Melt the Cheese: Place the bowls under a broiler for 2-4 minutes, just until the cheese is gloriously melted and bubbly. Watch carefully to prevent burning!
Optional: A sprinkle of fresh parsley adds a lovely touch of green.

Laziest French Onion Soup Recipe FAQs
How do I ensure the onions caramelize quickly without constant stirring?
Absolutely! The “laziest” part of this recipe is precisely this step. Thinly slicing your onions is key, as it increases their surface area for faster caramelization. Then, toss them with your fat (olive oil or butter), cover the pot, and let them cook on low heat. Stirring only every 10 minutes or so is enough; the cover traps steam, which helps soften the onions and encourages them to release their sugars without constant attention.
Can I use chicken broth instead of beef broth for this recipe? If so, how will it affect the flavor?
Yes, you can definitely use chicken broth! While beef broth provides a classic, deep, and rich savory flavor that’s traditional for French onion soup, chicken broth is a perfectly acceptable and delicious alternative. It will result in a slightly lighter flavor profile, which many people enjoy. I often make it with chicken broth when beef broth isn’t readily available, and it’s still wonderfully comforting!
How should I store leftover French onion soup and how long will it keep?
This soup is fantastic for leftovers, and the flavors often meld and deepen beautifully overnight! Once cooled, store any leftover soup in an airtight container in the refrigerator. It will keep well for about 3 to 4 days. Just remember to store the toasted baguette slices and cheese topping separately if you anticipate having leftovers of those components, as they are best added just before reheating.
Is it possible to freeze French onion soup, and if so, what’s the best way to do it?
Yes, this lazy French onion soup freezes like a dream! Make sure the soup has completely cooled. Portion it into freezer-safe containers or heavy-duty zip-top bags, leaving a little headspace for expansion. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy it, thaw it in the refrigerator overnight and then reheat gently on the stovetop or in the microwave. As mentioned in the storage tip, it’s best to toast fresh bread and add the cheese just before broiling to achieve that perfect gooey topping.
