What Is French Onion Soup?
Originating from France, as the name suggests, French Onion Soup is a soul-warming dish featuring caramelized onions in a robust broth, topped with toasted bread and melted cheese.
Ingredients
For the best results in your single serve French Onion Soup, pay close attention to the ingredients you select. Here’s what you need:
- Butter: It adds a layer of seasoning while sautéing the onions.
- Onion: Choose one small yellow onion and slice it thinly for the perfect caramelization. Yellow onions are naturally sweet, making them ideal for this dish.
- Garlic: A single clove delivers a subtle yet impactful aroma and flavor.
- Seasonings: Opt for dried thyme, salt, and black pepper. These classic seasonings enhance the soup’s overall profile.
- Red wine: Ideal for deglazing the pan and adding depth of flavor. If you’d rather skip the alcohol, using broth is a perfectly fine alternative.
- Flour: All-purpose flour is my go-to for thickening the soup. If you’re following a gluten-free diet, a gluten-free blend works just as well.
- Broth: While beef broth is traditional in French Onion Soup, quality store-bought options can be elusive. To avoid a metallic aftertaste, I use chicken broth for a consistently delicious outcome.
- French bread and cheese: Gruyere is the cheese of choice for authenticity. But don’t worry if you don’t have it on hand; Gouda, Swiss, Fontina, or Mozzarella make great substitutes.

The Art Of Caramelizing Onions For French Onion Soup
Caramelizing onions is the cornerstone of creating a luscious French Onion Soup. This process magically turns raw onion slices into sweet, sumptuous morsels that act as the dish’s flavorful foundation.
For this single serving recipe, you’ll need just one small onion, although the size isn’t a deal-breaker. Whether small or medium, you can’t really go wrong—the more onion goodness, the better the soup will be.
Start by slicing your onion into thin strips. Place these into a saucepan with melted salted butter and let the caramelization begin. During slow cooking, the onions release their natural sugars, giving them a delectable sweetness that elevates any dish they’re a part of. In terms of timing, aim for 25 minutes to achieve that perfect caramelized texture for this soup.
How To Make French Onion Soup
See the recipe box below for ingredient amounts and full recipe instructions.
- Melt the butter in a 2-quart saucepan over medium heat. Add the onions, garlic, thyme, salt and pepper and cook until the onions are very soft and caramelized, about 25 minutes.
- Add the wine, bring to a boil, reduce the heat and simmer until the wine has evaporated, about 5 minutes.
- Sprinkle the flour over the onions and stir. Reduce the heat to medium-low and cook for 10 minutes, stirring occasionally so that the flour doesn’t burn.
- Stir in the chicken broth and bring the soup back to a simmer, cook for 10 minutes.
- Taste and add additional salt, if necessary.
Prepping The Perfect Bread For Your French Onion Soup
Looking to elevate your French Onion Soup game? The bread matters—here’s how to prep the perfect slice that’ll complement your soup without stealing the spotlight.
While the soup is simmering, prepare the bread.
- Heat the broiler. Place the slice of French bread on a baking sheet. Sprinkle the Gruyere cheese over the top and broil until bubbly and golden brown, 3-4 minutes.
- Place the bread in a soup bowl and pour the soup over the top.
Expert Tips
- Gruyere Cheese: For that quintessential French Onion Soup flavor, you can’t go wrong with Gruyere. Its meltability and rich, smooth texture make it the top choice. For other cheese options, check out our Ingredient Notes.
- Choosing the Right Broth: Traditional recipes call for beef broth, but a high-quality store-bought version is often elusive. Many tend to have a metallic tang. To guarantee a satisfying soup, opt for chicken broth instead.

Frequently Asked Questions
Yellow, white, or red onions can all be used in making French Onion Soup. However, I lean towards sweet yellow onions for their balanced flavor profile.
If you find yourself with extra wine after cooking (it happens), you have a couple of options. For those who don’t drink wine regularly, try freezing it in ice cube trays. Next time you need a splash for a recipe, simply pop out a wine cube.
Not a fan of cooking with wine? No worries! While wine adds depth, it’s not essential. Feel free to use dry vermouth, brandy, or even just extra broth to deglaze the pan, as noted in the recipe steps.
You can store the soup sans the cheesy bread in an airtight container in the fridge for up to 3-4 days. To reheat, simply bring it to a boil on the stovetop. The cheesy bread should be prepared fresh for the best experience.

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.
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 make this every cold winter evening. So delicious!
I’m so happy you like the recipe, Linda. Thank you for letting me know.
Seriously love this recipe!
Our whole family loved this soup!
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.
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.
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.
Thank you, Teresa. I’m so happy you are enjoying the recipes.
