Easy French Onion Soup

This Easy French Onion Soup Recipe is completely homemade and perfect for a chilly day! Caramelized onions, melty cheese and crusty bread make this one of the best soups ever. It’s easy enough for a novice and delicious for everyone in the family.

Now that the weather has cooled off, it’s definitely soup season! One of my favorite soups is French Onion Soup, probably because there is a lot of melty cheese involved. Not only will you have a warm and delicious soup to serve, but your house will also smell amazing when the onions are caramelizing!

Ingredients needed for French Onion Soup

• 4 large yellow onions, sliced into crescents
• 3 tablespoon unsalted butter
• 2 tablespoons olive oil
• 1 teaspoon salt
• freshly ground black pepper
• 1 tbsp sugar
• 3 tablespoons all-purpose flour (skip if you want a gluten-free option)
• 6 cups broth (beef, chicken, or vegetable)
• 1/2 cup white wine (optional)
• 1 handful of fresh oregano or any fresh herb you like
• 1 crusty baguette sliced or cubed
• 2-3 cups gruyere cheese, shredded
• fresh parsley for garnish if desired

How to make This Super Easy Soup

1. For this recipe, I used a dutch oven to cook the onions and soup in. The heat of the cast iron helps with the onion caramelization. Add the butter and oil and melt over medium-low heat. After the butter stops bubbling, add the onions and stir to coat the onions. Cover and cook for 15 minutes on low.
2. Remove the lid and add salt, pepper, and sugar to get the caramelization going. Continue to cook on medium-low heat for about 30 minutes, stirring often, until the onions are nice and brown.
3. Add the flour to onions and stir for about 60 seconds. Add the broth, wine and herbs to the onions, and cook partially covered on low heat for about 40-45 minutes. While the soup is cooking, slice the bread into slices or large cubes and brown under broiler for a few minutes to get them crispy.
4. Pour the soup into individual serving bowls that are oven-safe. Top with the bread slices or cubes and then a generous amount of cheese. Place the bowls under the broiler in the oven until cheese is melted and bubbly. Remove from oven and allow to cool for a few minutes before serving. Enjoy, and remember, it’s VERY hot!!!

You can make this soup gluten-free or skip the wine.

This recipe is pretty simple and there are so many ways to adjust to your liking. If you are gluten-free, leave out the flour. You can also use whatever fresh herbs you have on hand. The wine is also optional but highly recommended. Ok, the wine is recommended for taste and also because you will have a full bottle of wine that has to go somewhere… Did I mention this soup is delicious with wine?? 😂 🍷

What type of onions to use for French Onion Soup?

I usually use basic yellow or white onions for French Onion Soup, but you can use any onion you like. Yellow and white onions create a nice sweetness and tend to be the least expensive. You can usually find in either of these in bulk bags which makes it even more convenient and cost-efficient. Red onions will work as well but tend to be a little more bitter and sweet onions are delicious but tend to be a little more expensive.

How do I get a melty cheesy top?

Gruyere cheese is the most common cheese used for french onion soup. I highly recommend it not only for its melty quality but for the nutty and salty flavors you get from Gruyere. However, if you do not have or like Gruyere, you can also use mozzarella or Monterey cheese since they both melt really well. Most grocery stores have cheese experts in the cheese section and they could guide you as well.

You will also need oven-safe bowls to melt the cheese on top. I usually used my Fiesta bowls or an oven-safe stoneware bowl, they never fail me. After you have cooked the soup, add some bread to the top and then a generous amount of cheese. Place the oven-safe bowl under the broiler in the oven for a few minutes until the cheese has melted and is nice and bubbly.
