To make this onion soup, I started by thinly slicing four large yellow onions.

I dropped some butter and olive oil into a large Dutch oven over medium-low heat.

Once the butter was melted I added the sliced onions to the pot.

I cooked the onions, stirring occasionally, until they were caramelized and golden brown which took about forty-five minutes.

I sprinkled some sugar over the onions and continued cooking for five minutes.

I added some minced garlic, salt and pepper to the pot.

I stirred well and continued cooking for two minutes.

I added some dry white wine and balsamic vinegar to the pot.

I continued cooking for a few minutes to allow the flavours to meld.

I added some beef broth and bay leaves to the pot.

I brought the soup to a boil and then reduced the heat to allow the soup to simmer for about thirty minutes.

While the soup was simmering, I placed slices of French baguette on a foil lined baking sheet.

I brushed the slices of baguette with olive oil.

I placed the baking sheet in the oven and toasted the baguette slices until they were golden brown.

Once the soup was ready I ladled it into oven safe bowls on a baking sheet.

I placed two slices of toasted baguette in each bowl of soup.

I placed slices of Swiss cheese on top of the baguettes.

I placed the baking sheet in the oven under the broiler until the cheese was melted and bubbly.

I carefully removed the baking sheet from the oven and allowed the soup to cool for a few minutes.

I sprinkled some fresh chopped parsley on top.

Then the homemade French onion soup was ready to serve.

Each spoonful is a journey through layers of flavor – the initial warmth of the broth, the sweetness of the onions, and the gooey richness of the melted cheese.

The accompanying crouton adds a satisfying crunch, completing the sensory experience.

French onion soup a timeless classic that has earned its place as a cherished dish, providing solace on chilly days or a touch of sophistication to any meal.

How to Make Easy French Onion Soup:

1. In a large pot or Dutch oven, melt the butter and 2 tablespoons of olive oil over medium-low heat. Add the sliced onions and cook, stirring occasionally, for about 40-50 minutes until the onions are caramelized and golden brown.
2. Sprinkle the sugar over the onions and continue to cook for an additional 5 minutes. The sugar will help enhance the caramelization.

4. Add the dry white wine and balsamic vinegar to the pot, and cook for a few minutes to allow the flavors to meld.
5. Add the beef broth and bay leaves to the pot. Bring the soup to a boil, then reduce the heat and let it simmer for about 20-30 minutes to allow the flavors to meld. Remove the bay leaves and discard them.
6. While the soup is simmering, preheat your oven to 400°F.
7. Place the slices of French baguette on a baking sheet and lightly coat one side with the remaining tablespoon of olive oil. Toast them in the oven for 5-7 minutes until they are golden brown on the edges and crispy. Keep a close eye on them to make sure they don’t burn. Set them aside.
8. Turn your oven broiler on high.
9. Ladle the hot soup into oven-safe bowls. Place 2 slices of toasted baguette on top of each bowl of soup.

13. Serve and enjoy!

FAQS:

How do I store leftover French Onion Soup? Store leftover soup in an airtight container in the refrigerator for 3-4 days. Reheat gently on the stovetop, adding additional broth if needed to reach the desired consistency.

What can I use instead of the dry white wine? The white wine gives the soup the best flavor, but it can be substituted with white wine vinegar, white grape juice, or red wine vinegar, which are all great options.

What is the purpose of adding sugar to caramelized onions? Sugar aids in the caramelization process by promoting browning. It helps break down the onions’ natural sugars, enhancing the sweetness and depth of flavor.

Can I use sweet onions instead of yellow onions? Yes, sweet onions can be used for a milder flavor in French Onion Soup. Adjust the sugar quantity accordingly based on the sweetness of the onions.
