Step-by-Step Instructions

1. Season and Sear the Short Ribs

Start by patting the beef short ribs dry with paper towels to ensure a good sear. 

Sprinkle them generously with kosher salt and black pepper. 

Heat 2 tbsp of olive oil in a Dutch oven over medium-high heat until shimmering. 

Add the short ribs and sear for 3-4 minutes per side until they develop a deep golden-brown crust. 

Work in batches if needed to avoid crowding the pot. 

Once seared, transfer the ribs to a plate and set aside.

2. Caramelize the Onions

In the same Dutch oven, lower the heat to medium and add 4 tbsp of unsalted butter. 

Once melted, add the thinly sliced yellow onions. 

Stir occasionally with a wooden spoon for 20-25 minutes, letting the onions soften and turn a deep golden brown. 

If they start to stick, add a splash of water to deglaze the pan. This slow caramelization is key to that sweet, rich flavor, so don’t rush it!

3. Add Garlic and Flour

Once the onions are caramelized, stir in the minced garlic and cook for 1 minute until fragrant. 

Sprinkle 1 tbsp of all-purpose flour over the onions and stir constantly for 1-2 minutes to cook out the raw flour taste. This helps thicken the soup and gives it a velvety texture.

4. Deglaze with White Wine

Pour in 1/2 cup of dry white wine, scraping up any browned bits from the bottom of the pot with your wooden spoon. 

Let the wine simmer for 2-3 minutes until it reduces slightly, intensifying the flavor and adding a subtle brightness to the soup.

5. Simmer the Soup

Return the seared beef short ribs to the pot, along with any juices on the plate. 

Add 6 cups of beef broth, 2 sprigs of thyme, and 1 bay leaf. 

Bring the mixture to a boil, then reduce to a low simmer. 

Cover and cook for 2.5-3 hours, stirring occasionally, until the short ribs are fork-tender and falling off the bone.

6. Shred the Beef

Carefully remove the short ribs from the pot using tongs and place them on a cutting board. 

Let them cool slightly, then shred the meat using two forks, discarding the bones and any excess fat. 

Return the shredded beef to the soup and stir to combine. 

Remove the thyme sprigs and bay leaf.

7. Toast the Baguette Slices

Preheat your oven to 400°F (200°C). 

Place the baguette slices on a baking sheet and toast for 8-10 minutes, flipping halfway, until golden and crispy. Set aside.

8. Assemble and Broil

Ladle the soup into oven-safe soup bowls. 

Place a toasted baguette slice on top of each bowl and sprinkle generously with grated Gruyère cheese. 

Place the bowls on a baking sheet and broil on high for 2-3 minutes, watching closely, until the cheese is bubbly and golden. Serve immediately.

Tips for Success

To make your French onion beef short rib soup turn out perfectly every time, keep these pointers in mind. I’ve learned a few tricks from trial and error that can make a big difference:

  • Take your time caramelizing the onions; low and slow is the way to go for maximum sweetness.
  • Use a good-quality beef broth for a richer flavor, or make your own if you have time.
  • Don’t skip the wine; it adds depth, but you can substitute with extra broth if needed.
  • Shred the beef finely for even distribution in the soup.
  • Keep a close eye on the cheese while broiling to avoid burning.

FAQs

1. Can I make this soup in a slow cooker?

Absolutely! After searing the short ribs and caramelizing the onions in a skillet, transfer everything to a slow cooker with the broth, thyme, and bay leaf. Cook on low for 8 hours or high for 4-5 hours until the beef is tender. Shred the beef, then proceed with the bread and cheese topping.

2. What can I use instead of Gruyère cheese?

If Gruyère cheese is hard to find or too pricey, try mozzarella, provolone, or even Swiss cheese. They’ll still give you that melty, gooey topping, though the flavor will be slightly milder.

3. Can I make this soup ahead of time?

Yes, this soup is perfect for making ahead. Prepare the soup base and store it in the fridge for up to 4 days. When ready to serve, reheat, add the toasted baguette slices, and top with Gruyère cheese before broiling.

4. Is there a non-alcoholic substitute for the wine?

You can skip the dry white wine and use extra beef broth or a splash of white grape juice with a teaspoon of vinegar for a similar tangy depth.

5. How can I make this soup vegetarian?

To make a vegetarian version, replace the beef short ribs with hearty mushrooms like portobello or cremini and use vegetable broth instead of beef broth. The caramelized onions will still provide plenty of flavor.
