Ingredients

For the Soup Base

3 pounds beef short ribs
6 yellow onions, thinly sliced
3 tablespoons butter
2 tablespoons olive oil
4 sprigs fresh thyme
4 garlic cloves, minced
2 bay leaves
8 cups beef stock

How to Make French Onion Short Rib Soup with Gruyère Toast

Step 1: Season the Ribs

Season the short ribs with salt and pepper.

Step 2: Brown the Short Ribs

In a large Dutch oven, heat olive oil over medium-high heat. Brown the short ribs on all sides. Remove them from the pot and set aside.

Step 3: Caramelize Onions

Add butter and more olive oil to the same pot. Stir in the sliced onions. Cook on low heat for 30 to 40 minutes, stirring occasionally until they are caramelized and golden brown.

Step 4: Add Garlic and Deglaze

Add minced garlic to the pot and cook briefly. Pour in red apple vinegar to deglaze it by scraping up any browned bits from the bottom of the pot. Let it reduce for a few minutes.

Step 5: Simmer with Stock

Add beef stock, thyme, bay leaves, and return the browned short ribs to the pot. Cover it and let it simmer for 2.5 to 3 hours until the meat is fall-apart tender.

Step 6: Prepare Gruyère Toast

Toast baguette slices under the broiler until golden brown. Top each slice with shredded Gruyère cheese and return them to broiler until melted and bubbly.

Step 7: Serve

Remove bay leaves and thyme stems from soup. Ladle into bowls and top with Gruyère toast. Serve hot for a delightful dining experience!

Season Generously: Don’t hesitate to adjust seasoning throughout cooking. Taste as you go to achieve the perfect balance of salt and pepper.
Thicken Wisely: If you prefer a thicker soup, consider adding a cornstarch slurry towards the end of cooking for added body without compromising flavor.
Garnish Creatively: Experiment with garnishes like fresh thyme or chives to add color and freshness to each bowl before serving.
Broil Wisely: When broiling the Gruyère toast, keep an eye on it to avoid burning. You want it bubbly and golden brown.

Common Mistakes to Avoid

When making French Onion Short Rib Soup with Gruyère Toast, it’s easy to overlook a few crucial details. Here are some common mistakes to avoid for the best results.

Skipping the caramelization: Not spending enough time caramelizing the onions can lead to a less flavorful soup. Take your time and cook them until they’re golden brown for maximum sweetness.
Overcrowding the pot: If you add too many short ribs at once, they won’t brown properly. Brown them in batches to ensure even cooking and flavor development.
Ignoring seasoning adjustments: It’s vital to taste and adjust the seasoning as you cook. Don’t forget that flavors deepen during simmering, so check before serving.
Using low-quality ingredients: The quality of your beef stock and cheese greatly affects the soup’s flavor. Opt for high-quality beef stock and good Gruyère cheese for an authentic experience.
Not letting it rest: Serving the soup immediately after cooking can result in a bland taste. Allow it to rest for a few minutes after cooking; this helps meld the flavors together.
