• 6-8 cups low sodium chicken broth
• 1/2 cup tamari or low-sodium soy sauce

Pro Tips

To elevate your French Onion Short Rib Soup from good to extraordinary, focus on these critical techniques:

First, don’t rush the onion caramelization process. While the recipe calls for about 10 minutes, giving them a few extra minutes until they’re deeply golden (but not burnt) will develop that signature sweet, complex flavor that forms the backbone of the soup. Stir occasionally and adjust the heat as needed to prevent burning.

Second, for the most tender short ribs, look for cuts with good marbling and make sure they’re fully submerged in the broth during cooking. If your short ribs aren’t falling-off-the-bone tender after the suggested cooking time, don’t hesitate to give them an additional 30 minutes in the oven. The meat should easily pull apart with minimal resistance.

Lastly, for the perfect cheesy toast, use a crusty French bread that’s at least a day old and slice it thick enough (about 3/4 inch) to hold up when placed atop the soup. For the ultimate cheese pull, don’t skimp on the Gruyère – its nutty flavor and excellent melting properties are essential to authentic short rib onion soup flavor.

Instructions

Step 1: Preheat the Oven
Preheat your oven to 325°F (165°C).

Step 2: Cook the Onions
In a large oven-safe Dutch oven, melt the butter over medium-high heat. Add the thinly sliced onions and cook for about 10 minutes until they begin to soften and lightly caramelize. Season with black pepper.

Step 3: Add Aromatics and Short Ribs
Stir in the shallots, garlic, fresh thyme, sage, and a pinch of red chili flakes. Add the bone-in short ribs to the pot. Pour in 6 cups of chicken broth, then add the tamari, bay leaves, and star anise (if using). Cover the Dutch oven and transfer it to the oven.

Step 4: Roast the Short Ribs
Roast for 2 1/2 to 3 hours, until the short ribs are tender and falling off the bone. Add the baby carrots to the pot during the last 1-2 hours of cooking.

Step 5: Shred the Meat
Remove the Dutch oven from the oven. Discard the bay leaves and star anise, and remove the bones from the short ribs. Lightly shred the meat and return the pot to low heat on the stove. Taste the soup and adjust the seasoning with salt if necessary.

Step 6: Prepare the Cheesy Toast
Preheat the oven to 425°F (220°C). Arrange the French bread slices on a baking sheet and toast for 10 minutes until they are dry and slightly crisp. Switch the oven to broil, top each slice with shredded Gruyère, and broil for 2-3 minutes until the cheese is bubbly and golden.

Step 7: Serve the Soup
Ladle the rich, savory short rib soup into bowls. Top each serving with a slice of cheesy toast. Garnish with black pepper and fresh thyme, and enjoy!

Variations

For a wine-enriched version of this hearty short rib onion soup, add 1 cup of dry red wine like Cabernet Sauvignon after cooking the onions. Allow the wine to reduce by half before adding the other ingredients, creating an even more complex flavor profile that pairs beautifully with the beef.

For a gluten-free adaptation, simply replace the French bread with your favorite gluten-free baguette and confirm your tamari is certified gluten-free. The soup itself is naturally gluten-free, making this an easy adjustment for those with sensitivities.

Looking for a lighter version? Use boneless beef short ribs and trim visible fat before cooking. After cooking, chill the soup overnight in the refrigerator, which allows fat to solidify on top for easy removal. Reheat gently and continue with the recipe for all the flavor with significantly less fat.

Storage and Serving

This French Onion Short Rib Soup actually improves with time, making it perfect for meal prep. Store leftovers in airtight containers in the refrigerator for up to 4 days. For longer storage, freeze the soup (without the cheesy toast) for up to 3 months. The flavors will continue to meld and deepen, making day-two soup even more delicious than the first serving.

For an elegant dinner party presentation, serve the soup in individual oven-safe crocks. Place the bread and cheese directly on top of each filled crock and broil until the cheese is bubbly and golden – this creates an impressive presentation with cheese cascading down the sides.

For a complete meal, serve smaller portions of this rich soup alongside a crisp green salad dressed with a simple vinaigrette. The bright, acidic notes of the salad perfectly balance the deep, savory richness of the short rib onion soup.

FAQs

Can I make this soup in a slow cooker?
Yes! Brown the onions and sear the short ribs on the stovetop first, then transfer everything to a slow cooker. Cook on low for 7-8 hours or until the short ribs are tender. Prepare the cheesy toast separately just before serving.

What can I substitute for Gruyère cheese?
If Gruyère isn’t available, Swiss cheese is the closest substitute. Other good alternatives include Emmental, Jarlsberg, or a combination of provolone and Parmesan for a similar nutty, melty quality.

Can I use boneless short ribs instead?
Absolutely. Boneless short ribs work well and make serving easier. However, bone-in ribs generally provide more flavor to the broth. If using boneless, reduce the weight to about 3 pounds.

How can I make this soup less rich?
For a lighter version, use less butter for cooking the onions and substitute beef broth with additional chicken broth. You can also skim off fat after cooking or prepare the soup a day ahead and remove solidified fat after refrigeration.

Is there a way to speed up this recipe?
While the slow cooking is essential for tender short ribs, you could use a pressure cooker or Instant Pot. Sauté onions using the sauté function, then pressure cook the short ribs for about 45 minutes with a natural release. The flavor won’t be quite as developed, but it will still be delicious.
