    Bonjour! And that is the extent of French that I know.

    Luckily speaking French is not a requirement for making a delicious cup of French onion soup. In fact, it's easy even if you don't really know how to cook! This recipe is a classic and is pretty simple.

    ★ Why You'll Love this Recipe ★

    I may not speak French, but I do know that the French make some very delicious foods. Particularly this little soup, you may have heard of it... French onion soup? You know, the kind with the melted cheese on top. Yeah, thought you may have heard of it.

    French Onion Soup

    There's a little something special about this french onion soup recipe and that's the Marsala wine. I personally can't get enough of Marsala's earth flavor. You could also use Sherry or a dry white wine if you don't have Marsala on hand.

    ★ Ingredients You'll Need ★

    Here's a look at what you'll need to gather to make this yummy soup.

    French Onion Soup Ingredients

    You'll need 13 ingredients to make this recipe: croutons, fresh thyme, salt, provolone cheese, Swiss cheese, grated Parmesan cheese, pepper, malt vinegar, Marsala wine, beef broth, sugar, butter, and of course lots of onions!

    ★ How to Make this Recipe ★

    French Onion Soup is surprisingly easy to make. Check out the process, step-by-step (full recipe instructions, below).

    How to Make French Onion Soup
    • Cook onions.
    • Add to pot with herbs, broth and wine.
    • Ladle into ramekins or oven-safe bowls
    • Add croutons.
    • Layer with cheeses.
    • Bake.
    • Serve hot!

    ★ Tips & FAQs ★

    Does this soup have to be baked?

    Yes, so you'll need some oven safe ramekins to get that melty cheese on top.

    To properly make French onion soup with the melted cheesy top, you will need oven-safe ramekins.

    What makes this recipe special?

    The Marsala wine and sugar are my secret ingredients to this French onion soup. Trust me it's worth the trip to the liquor store to get the wine. And with the left over wine you can try my Chicken Marsala recipe. Also one of my favorite dishes!

    I pretty much like anything cooked in wine, really. So, if you're a french onion soup lover, like me, then you will really enjoy this. Also, as with almost all of our recipes, its super easy to make.

    Storing Leftovers

    You can store leftover soup broth and onions in the fridge for up to 5 days. The croutons and cheese topping do not store well. So I recommend just saving the soup broth and adding fresh croutons and cheese to the top when you're ready to reheat. Reheat by warming the broth in the microwave, then assemble the bowls with croutons and cheese and bake as directed.

    Instructions

    • Bring beef broth to a boil in a large pot. Add sugar and malt vinegar. Reduce heat and simmer for 5 minutes.
    • Meanwhile, in a skillet over medium-high heat, sauté onions and thyme in butter until caramelized, about 3-5minutes. Scoop out onions and add to pot of beef broth. Deglaze the skillet by adding Marsala wine; bring to a boil and then scrape the sides. Carefully pour wine with flavorful onion bits into the pot of broth. Finally, season broth with salt and pepper to taste.
    • Ladle soup into oven-safe bowls or ramekins and place a handful of croutons in each. Sprinkle on Parmesan and Swiss cheese then layer 2 slices of provolone on top.
    • Place bowls on a cookie sheet and broil on low in a preheated oven until cheese bubbles and turns golden brown. About 5-7 minutes.

    Notes

    For added flavor be sure onions are caramelized but not burnt. Adjust heat as needed. Onions should be translucent with a light caramel brown color when done.
    Add fresh or dried thyme in with butter and onions to bring out the most flavor of this herb.
    You can skip the step of deglazing the onion skillet and add the Marsala wine directly to the broth, however, you'll miss out on some good flavor!
