A hot bowl of french onion soup is the perfect meal on a crisp, cool day. I especially love it when there's a thick chunk of French bread topped with glorious melted cheese floating in the middle of the bowl.

Why This Recipe Works

  • This French Onion Soup is absolutely delicious and so easy to make.
  • It's made with one small onion which cooks low and slow and beautifully caramelizes giving the soup a wonderful flavor.
  • This small batch soup recipe yields one large bowl of soup.

Ingredient Notes

See recipe box below for ingredient amounts and full recipe instructions.

  • Butter: I recommend using salted butter.
  • Onion: Use 1 small yellow onion, thinly sliced.
  • Garlic: 1 clove of garlic adds great flavor.
  • Seasonings: Dried thyme, salt, and black pepper.
  • Red wine: This helps to deglaze the pan after the onions have cooked.
  • Flour: To thicken the soup. I typically use all-purpose flour but you can you a gluten-free blend instead.
  • Chicken broth: Typically, french onion soup is made with beef broth but good store-bought beef broth is hard to come by. I've found that most packaged beef broth has a slightly "tinny" taste. Instead, I use chicken broth. It makes the soup perfect every single time.
  • French bread and cheese: For the toasty cheesy bread on top. I like using a crunchy bread and Gruyeré cheese but you can use any type of bread and cheese you prefer.

How To Make This Recipe

This soup begins with onions - plenty of sliced onions.

Since this french onion soup recipe yields a single serving, I use one small onion. In truth, the size of the onion doesn't completely matter. It could be small or it could be medium - in the case of french onion soup, the more onions the better.

  1. The onion is sliced into thin strips and added to a small saucepan with melted butter. The onions caramelize which means that as the onions slowly cook, the natural sugars in the onions release and result in a wonderful sweetness that will transform any dish they are added to. The process of caramelizing onions takes a little bit of time, for this soup recipe I recommend cooking the onions for 25 minutes.
  2. After the onions have caramelized, add in a little red wine and cook it down. Then add in a little flour to thicken the soup, and then pour in the broth.
  3. Make sure you don't leave out the glorious chunk of cheesy bread which is, in my opinion a complete necessity in French onion soup.

Expert Tips

  • Traditional french onion soup calls for Gruyere cheese and I highly recommend it. Gruyere is rich, it's smooth and it melts easily.
  • Another key ingredient to a good french onion soup is the broth. Typically, french onion soup is made with beef broth but good store-bought beef broth is hard to come by. I've found that most packaged beef broth has a slightly "tinny" taste. Instead, I use chicken broth. It makes the soup perfect every single time.

Frequently Asked Questions

What Kind Of Onions Do You Use For French Onion Soup?

You can use white, yellow or red onions for French onion soup. But to make it the classic way, you will need 1 small to medium-sized yellow onion, peeled and thinly sliced for this small batch recipe.

What Should I Do With Leftover Wine?

Leftover wine…is there really such a thing? Sure, you could always pour a glass for yourself and sip on it while cooking or relaxing. But what if you only use wine for recipes?
If that’s the case, you can freeze wine by pouring the wine into plastic ice cube trays and placing the trays in the freezer. When you want to use a little wine in a recipe, pop out one of the frozen wine cubes and add it to your recipe.

What Size Pot Should I Use For This French Onion Soup For One?

For this soup recipe I use a 2-quart saucepan. For best results use a pot of similar size.

    I’m so glad I found your site. I have been a widow for many years but can never seem to be able to make dishes for just one or two. As a result, like several others, I end up eating the same thing for 3 or more days. This is just what I’ve been looking for. I love it !!! Thanks so much.

    1. Thank you so much for your kind note, Elaine. I’m so happy you found our site and hope you find many new recipes to try.

    I am a senior citizen who lives alone. I am hungry for chicken paprikash and cabbage rolls, how do I cut these recipes down so I am not eating them for 3 days? I have been alone for 13 years and at times, to get the flavor I want, I end up cooking like I was back with my family when I was growing up, cooking for a family of 7 that all ate at least seconds. In all these years I have only made one decent pot of chili and ate it for days. I know you can freeze it, but, it never tastes the same to me. If you have a formula to cut down recipes, I hope you will share it.

    1. Hi Jackie, I’m so happy you found our site and I hope you find many new recipes to try. I love cabbage rolls too and would love to work on creating a small batch cabbage roll recipe. Hopefully we will have one on the site for you soon.

    2. I too have been a widow for over 20 years and love to cook. I share a lot of things I make with neighbors but getting too expensive. I also love this blog and I would love to have cabbage rolls for 2. It sometimes is easy enough to 1/2 a recipe but your recipes make it so much easier. Looking forward to many more delicious recipes.

  3. Renee - Kudos Kitchen

    French onion soup is a family favorite here, but I’d never think to make it just for myself. I’m anxious to try your recipe and make it one day just for me!

  4. Patricia @ Grab a Plate

    This is one of my favorites, and I NEVER make it at home! I need to change that and your single-serve recipe is perfect for that! This looks so good, and I can’t wait to try it!
