French Onion Soup with Marsala Wine - Mighty Mrs | Super Easy Recipes (2024)

FAQs

How do you deepen the flavor of French onion soup? ›

A few sprigs of thyme and a bay leaf elevate the soup even more, but I take it a step further, adding a splash of fish sauce for complexity and depth—don't worry, it won't taste fishy—and a hit of cider vinegar to balance some of that oniony sweetness.

There's a little something special about this french onion soup though 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.

Wine is optional to deglaze the pan and add flavour to the soup. I recommend a dry white or red wine, such as a good quality Pinot Grigio/Gris, Sauv Blanc, Sémillon, Chardonnay, Merlot or Pinot Noir. Generally, if you can't drink it, don't cook with it.

Infusing the soup with a richer taste is as easy as quickly sauteing crushed garlic before pouring the soup in. Some soft, buttery garlic sauteed in earthy olive oil is the perfect addition to enrich canned French onion soup.

"If your broth is lacking in savory richness, try adding roasted onion, tomato paste, mushrooms, seaweed, soy sauce, or miso. These ingredients add umami flavor and depth to broth," she says.

Alcohol: We use sweet vermouth (Dolin) and Lillet Blanc. You can substitute sweet vermouth with sherry (not sherry cooking wine) or brandy. Lillet Blanc is similar to dry white wine but more aromatic. Your favorite dry white wine is fine.

Due to the fortifying process, Marsala wine lasts 4-6 months after opening. Although it won't go bad if you keep it in the cupboard longer than six months after opening, it will start to lose its flavor and fragrance. It's best to store Marsala in a cool, dry place much like you would olive oil.

What can I use instead of marsala wine? The best substitute for marsala wine is madeira, another kind of fortified wine with a similar flavour profile. Other alternatives include other fortified wines such as commandaria, sherry, vermouth, and port.

Marsala Varietals

The younger wines, like the ones you'll find at the bottom shelf of your liquor store, are best for cooking. Sadly, many people don't realize that Marsala makes a great drinking wine, usually as either an aperitif, or appetizer, or a dessert wine.

Can you drink Marsala wine on its own? ›

Traditionally Marsala is sipped neat, but it also has culinary applications. Drier styles add complexity to herb-filled savory dishes, while more luscious versions can go into desserts like zabaglione, an airy custard made with sugar and egg yolks. Now, it's finally getting its due as a back-bar secret weapon.

Though both were acceptable, tasters found that dry Marsala offered more depth of flavor, while sweet Marsala added sweetness and some flavor but wasn't as complex. The takeaway? For both savory and sweet applications, we suggest using dry Marsala if a recipe doesn't specify a style.

If you prefer not to use Wine, you can substitute 3 Tablespoons white wine vinegar + chicken or beef broth to make 3/4 cup.

Well, nothing will quite replace some nice Burgundy wine in the soup. If you cannot, just use beef broth, but it won't taste as good. I have been making French onion soup for decades and have never used wine. The secret is a great beef broth, and good onions of course.

That said, French onion soup's other key ingredients are beef broth and gruyere cheese, which accounts for its utterly decadent and robust balance of sweet, creamy, and umami. For umami-rich beef dishes and ultra-creamy cheeses, red wine's complexity, fruitiness, and bitter finish are the optimal choices.

Use fresh vegetables, high-quality meats or broth, and fresh herbs to add depth of flavor. Add acidity: A squeeze of lemon or lime juice, a dash of vinegar, or a splash of wine can brighten the flavors of a soup and make it taste more complex.

A squeeze of citrus, a dollop of yogurt or a drizzle of cream, a dusting of cheese or a good chile powder, a sprinkling of some herbs or croutons — all can take a perfectly fine soup into the realm of the delectable. Even a spiral of good olive oil to finish and some coarse sea salt can do wonders.

The caramelized onions for this soup cook more quickly due to a pinch of baking soda but still have that deep, slow-cooked flavor. Topping the soup with hot, cheesy toasts prepared while the soup simmers, eliminates the need to bake the soup in specialty French onion soup bowls.
