    Why This Recipe Stands Out

    We are a big fan of homemade soups and this Easy French Onion Soup is no exception. It’s rich, flavorful, and the perfect comfort food for the colder months. Here’s why we love this recipe:

    • Easy: French Onion Soup is one of the easiest soups ever. The recipe requires minimal ingredients, and the process is simple, resulting in a soup that’s easy to make at home.
    • Minimal Ingredients: You’ll be amazed at how much flavor comes from such simple ingredients.
    • Onion Caramelization: Thanks to the slow caramelization of the onions, the soup comes out extremely flavorful.
    • Flavor: The time spent caramelizing the onions results in a soup that’s rich and full of flavor.
    • Versatile: This soup is the perfect start to any meal, like our Mustard Chicken or 30 Minute Risotto Putanesca.

    Key Ingredients

    • Yellow Onion – The star of our soup, these are thinly sliced and caramelized to bring out their natural sweetness and depth of flavor.
    • Butter – We use butter to caramelize the onions. It adds a rich, creamy flavor that takes this soup to the next level.
    • Beef, Chicken, or Vegetable Broth – We use low-sodium broth as the base of our soup. It adds a savory, umami flavor that complements the sweetness of the onions.
    • Gruyere and Provolone Cheese – These two cheeses are grated and sprinkled on top of the soup. They melt beautifully and add a delicious, gooey layer of flavor.

    Substitutions and Variations

    This classic French onion soup is a crowd-pleaser, but there’s always room to put your own twist on a dish. Here are some of our favorite variations:

    • Cheese: The combination of Gruyere and Provolone is classic, but feel free to experiment with different cheeses. Swiss, Mozzarella or even a sharp Cheddar can work well in this recipe.
    • Vegetarian: If you want to make this soup vegetarian, substitute the beef or chicken broth with a high-quality vegetable broth. You won’t even miss the meat! Or check out our vegan French onion soup recipe.
    • Herbs: While we love the earthy flavor of thyme, you can try using other herbs like rosemary or oregano for a different flavor profile.
    • Spices: If you like your soup on the spicy side, add a pinch of red pepper flakes or a dash of hot sauce.

    How to Make Easy French Onion Soup

    Step 1: In a large Dutch oven, cook sliced onions in melted butter until tender and caramelized.

    Step 2: Add flour, sugar, salt, pepper, and thyme to the onions. Simmer and stir constantly for 5-7 minutes.

    Step 3: Pour in the broth and let it simmer for 25 minutes. Then, divide the soup into 4 ramekins and top each with a few slices of baguette and a generous amount of Gruyere and Provolone cheese.

    Step 4: Place the ramekins on a baking sheet and broil for a few minutes until the cheese is melted and starts to brown. Serve immediately.

    For full list of ingredients and instructions, see recipe card below.

    Best French Onion Soup Recipe

    What to Serve with Easy French Onion Soup

    Side Dishes

    • French onion soup pairs well with a variety of side dishes. A simple green salad or a Caesar salad can be a refreshing accompaniment to the rich, savory flavors of the soup. The crisp, fresh greens provide a nice contrast to the warm, comforting soup.
    • You can also serve some crusty bread on the side. Baguette or a hearty whole grain bread are great choices for soaking up the delicious broth. You can even toast the bread and top it with melted Gruyère cheese to mimic the flavors of the soup.

    Appetizers

    • If you're serving French onion soup as a starter, you might want to offer some appetizers to go with it. Cheese and charcuterie boards are always a hit, and they can be a great way to start off a dinner party. Also, smoked salmon vol au vents will be a perfect starter at any party.

    Entrees

    • If you're looking to make a full French-inspired meal, consider serving the soup as a starter to a main course like coq au vin or steak chateaubriand.
    • You can also pair it with a simple sandwich like a ham and cheese or a turkey club for a comforting, satisfying meal.

    Frequently Asked Questions

    Why do I need to caramelize the onions for so long?

    The long caramelization process is what gives French onion soup its rich, sweet flavor. It allows the natural sugars in the onions to come out and develop, resulting in a deep, savory base for the soup.

    Can I use pre-shredded cheese for this soup?

    While pre-shredded cheese will work, it's best to shred your own Gruyere and Provolone for this recipe. Freshly shredded cheese will melt more smoothly and give your soup a better texture and flavor.

    How do I know when the soup is done simmering?

    The soup is done simmering when the flavors have melded and the onions are very soft. This usually takes about 25 minutes after adding the broth.

    How long does French onion soup keep?

    French onion soup can be kept in the refrigerator for up to 3 days. Just make sure it's stored in an airtight container to maintain its freshness and flavor.

      This soup preparation seems to be easy yet little bit complicated. I feel sauteing for 50 minutes needs patience and perfection.
      It is a best tip to know that we can freeze this soup for three months. I would like to make this with perfection and store it in my freezer.

      Hi! I would love to link your recipe in a blog post that I'm preparing. It's for a challenge that I designed to do with my 10-year-old daughter, and this soup would be one of January's dish options. I'd like to embed a picture as well if possible, maybe to use it in the post or in my Pinterest Graphic. Would that be ok with you? Thank you!

      Why can i not access the recipe? I was able to the other day to review the list of ingredients, but now when selecting the link to view, all that comes up is the comments/reviews and I am being bombarded by advertisements that make it extremely difficult to navigate your site? Any help would be appreciated as I have plans to make this for dinner tonight...

      I tried this recipe tonight and was not very fond of it. While the ingredients are high quality, I found the final product far too rich and salty. Adding flour seemed unnecessary and made the broth thick, the added salt was redundant as the stock already has salt, and I omitted the sugar as the onions have natural sugars. I was not a fan, but perhaps that is my personal preference. My husband was also not a big fan. He did not hate it, but couldn't eat more than half a bowl... and he's a healthy eater. I followed the recipe exactly, except for omitting the sugar.

        Kelly, thank you for your feedback! Sorry the recipe wasn't to your liking. I might give it a go again to see if anything needs tweaking.
        One thing I didn't mention in the recipe card is that I always use low sodium broth therefore my soup never comes out too salty. I'm going to add this note to a recipe.
        Aside from that, this French Onion Soup is a recipe that I love, make often and have gotten great reviews for. Sorry again it wasn't what you expected and I appreciate you sharing anyway!

      It tastes delicious, was time consuming but easy. I prefer The more broth style French onion without the flour. But the taste makes it worth it. Yumm... and yes i chose Toasted homemade sour dough and only Swiss. Plus added some cheese/garlic croutons for a little more flavor in another bowl to try both ! Thank you for the recipe.

          You can substitute Gruyere and Provolone with some of the low sodium cheeses like Mozzarella, Emmental or Swiss.
