Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Beef short ribs
Short ribs are the heart of this soup. Their marbling breaks down slowly during cooking, enriching the broth with a deep, meaty flavor and giving you tender pieces of beef that feel luxurious in every spoonful.

Yellow onions
Onions provide the signature sweetness of French onion soup. Cooking them low and slow allows their natural sugars to caramelize, creating the foundation of flavor for the entire dish.

Butter
Butter helps the onions soften and caramelize evenly. It adds richness and rounds out the sharper notes of the onions as they cook.

Olive oil
A small amount of olive oil prevents the butter from burning and adds a subtle fruity undertone that supports the onions and beef.

Garlic
Garlic enhances the savory profile of the soup without overpowering it. When gently cooked, it adds warmth and depth.

Beef stock
A good-quality beef stock reinforces the flavor of the short ribs and creates a full-bodied broth. Homemade or low-sodium options work best.

Dry white wine
White wine deglazes the pot and lifts the caramelized bits from the bottom, adding acidity and balance to the richness of the soup.

Fresh thyme
Thyme brings a gentle herbal note that complements both the beef and the onions beautifully.

Bay leaves
Bay leaves add subtle complexity during the long simmer, rounding out the broth.

Salt and black pepper
These seasonings tie everything together and should be adjusted carefully at the end.

Baguette
The baguette serves as the base for the cheesy toast, providing crunch and structure.

Gruyère cheese
Gruyère melts smoothly and delivers a nutty, savory flavor that defines the classic topping for French onion soup.

Directions

Begin by seasoning the short ribs generously with salt and black pepper. In a large, heavy-bottomed pot, heat olive oil over medium-high heat and sear the ribs on all sides until deeply browned. Remove them and set aside. Lower the heat, add butter, and stir in the sliced onions. Cook slowly, stirring often, until the onions are deeply caramelized and golden. This step takes patience but rewards you with incredible flavor.

Add garlic and cook briefly, then deglaze the pot with white wine, scraping up the browned bits. Return the short ribs to the pot, add beef stock, thyme, and bay leaves, and bring to a gentle simmer. Cover and cook until the ribs are fork-tender. Remove the ribs, shred the meat, and discard the bones. Return the meat to the soup and adjust seasoning.

Toast baguette slices, top with Gruyère, and broil until bubbly and golden. Serve the soup hot with the cheesy toast on top or alongside.

For a lighter version, reduce the cheese or serve the soup without toast. You can also experiment with herbs such as rosemary for a bolder aroma. Each variation keeps the soul of the dish intact while allowing you to tailor it to your preferences.
