Easy Homemade French Onion Soup Recipe

This easy Homemade French Onion Soup Recipe is 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, your house will smell amazing when the onions are caramelizing!

This recipe is pretty simple and there are so many ways to adjust to your liking. You can omit the flour and make it gluten-free, you can use whatever fresh herbs you have on hand or like, you can use your choice of cheese (although I highly recommend Gruyere) and the wine is optional but highly recommended as well. 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? 😉

For this recipe, I used a cast-iron pot to cook onions and soup in. The heat of the cast iron helps with the onion caramelization. You will also need oven-safe bowls to melt the cheese on top. I used my Fiesta bowls, they never fail me. It takes about 2 hours from start to finish for this soup, but it's so worth it.

Ingredients:

4 large yellow onions

3 tablespoons unsalted butter

2 tablespoons olive oil

1 teaspoon salt

Freshly ground black pepper

½ teaspoon sugar

3 tablespoons flour (skip if you want a gluten-free option)

6 cups beef, chicken, or vegetable broth ( I use beef because I think it tastes the best)

½ cup white wine, optional

A small handful of fresh oregano, chopped (or use whatever herbs you like)

1 baguette, sliced or cubed

2-3 cups shredded Gruyere cheese (or cheese of your choice!)

Fresh parsley, optional for garnish

Directions:

1. Cut onions into crescent slices. They don't have to be perfect but keep them similar in size so they cook evenly.

2. In a large pot, add butter and oil and melt over medium-low heat.

3. After the butter stops bubbling, add the onions and stir. Cover and cook for 15 minutes on low.

4. Remove lid and add salt, pepper, and sugar to get the caramelization going.

5. Continue to cook on medium-low heat for about 30 minutes, stirring often, until the onions are nice and brown. Keep an eye on heat level because you don't want them to stick and burn at the bottom.
