Ingredients List

• 3 lbs (about 1.4 kg) bone-in beef short ribs
• 2 tablespoons olive oil
• 2 tablespoons unsalted butter
• 4 large yellow onions, thinly sliced
• 4 cloves garlic, minced
• 1/2 cup (120ml) dry red wine, such as Merlot or Cabernet Sauvignon
• 8 cups (about 2 liters) high-quality beef broth
• 2 bay leaves
• 4-5 sprigs fresh thyme
• Salt and freshly ground black pepper, to taste
• 1 French baguette, sliced into 1-inch thick rounds
• 2 cups (about 8 oz) grated Gruyère cheese

Step-by-Step Instructions

1. Sear the Short Ribs: Pat the short ribs dry with a paper towel and season them generously on all sides with salt and pepper. Heat the olive oil in a large Dutch oven or heavy-bottomed pot over medium-high heat. Sear the short ribs in batches, turning until a deep brown crust forms on all sides, about 3-4 minutes per side. Remove the ribs and set them aside on a plate.
2. Caramelize the Onions: Reduce the heat to medium-low. Add the butter to the pot. Once melted, add the thinly sliced onions and a pinch of salt. Cook slowly, stirring occasionally, for 30-40 minutes, until the onions are deeply caramelized, soft, and jam-like. Do not rush this step; it is the foundation of your soup’s flavor. Add the minced garlic and cook for one more minute until fragrant.
3. Deglaze and Simmer: Pour the red wine into the pot to deglaze, scraping up any browned bits (the fond) from the bottom of the pot with a wooden spoon. Let the wine reduce by about half. Return the seared short ribs to the pot.
4. Build the Soup: Add the beef broth, bay leaves, and fresh thyme sprigs. Bring the mixture to a gentle simmer. Once simmering, reduce the heat to low, cover the pot, and let it cook for at least 2.5 to 3 hours, or until the short ribs are completely tender and falling off the bone.
5. Finish the Soup Base: Carefully remove the short ribs from the pot. Discard the bones, thyme sprigs, and bay leaves. Shred the meat with two forks and return it to the soup. Taste and adjust seasoning with salt and pepper as needed. Your magnificent French Onion Short Rib Soup base is now ready.
6. Prepare the Cheesy Croutons: While the soup is in its final moments of simmering, preheat your oven’s broiler. Arrange the baguette slices on a baking sheet and toast them lightly under the broiler for 1-2 minutes per side. Top each slice generously with grated Gruyère cheese and broil until the cheese is melted, bubbly, and golden brown.
7. Serve and Enjoy: Ladle the hot French Onion Short Rib Soup into oven-safe bowls. Top each bowl with one or two cheesy croutons and serve immediately.

Expert Tips for a Perfect French Onion Short Rib Soup

• The Slower, The Sweeter: The key to an authentic French onion flavor is patience. Caramelizing the onions over low heat draws out their natural sugars, creating a deep, complex sweetness that cannot be faked or rushed.
• Choose Bone-In Short Ribs: While boneless ribs work, bone-in short ribs release collagen and marrow into the broth as they cook, adding unparalleled richness and body to the final soup.
• Don’t Skip the Deglaze: Those browned bits stuck to the bottom of your pot after searing are pure gold. Deglazing with wine releases this concentrated flavor, adding an essential layer of complexity to your dish.
• Use High-Quality Broth: Since broth is the backbone of this soup, using a high-quality, flavorful beef broth or stock will make a significant difference in the final result.

Common Mistakes to Avoid

Prevent common issues with these simple tips:

• Rushing the onions: This results in steamed, not caramelized, onions. This will give you a harsh, raw onion flavor instead of a deep, sweet one.
• Not searing the meat properly: A pale, grey sear means you’re missing out on the Maillard reaction, which is crucial for developing a rich, beefy flavor base. Ensure your pan is hot and don’t overcrowd it.
• Skipping the resting time: While not a steak, allowing the finished soup to sit for 10-15 minutes off the heat before serving lets the flavors meld together beautifully.
• Using the wrong pot: A thin-bottomed pot can create hot spots, causing the onions and meat to scorch. A heavy-bottomed Dutch oven is your best friend for even heat distribution.

Storing Tips for the Recipe

This soup is an excellent candidate for meal prep, as its flavors only get better with time.

• Short-term storage: This soup does not do well at room temperature for extended periods. It should be refrigerated promptly.
• Refrigeration: Store the soup (without the cheesy croutons) in an airtight container for up to 4 days. Reheat gently on the stovetop.
• Freezing: Allow the soup to cool completely, then transfer it to a freezer-safe container. It will keep for up to 3 months. Thaw overnight in the refrigerator before reheating.
• Make-ahead option: You can prepare the entire soup up to 2 days in advance. Prepare the cheesy croutons just before serving to ensure they are crisp.
