Preparation Phase & Tools to Use

To prepare this incredible soup, you’ll need a few essential kitchen tools:

• Dutch Oven or Heavy-Bottomed Pot: Perfect for searing the beef and caramelizing onions evenly without scorching. It also retains heat well for long simmering.
• Tongs: Essential for turning and removing the beef short ribs while browning.
• Wooden Spoon or Silicone Spatula: Useful for deglazing and stirring during the onion caramelization process.
• Cheese Grater: Freshly grated cheese melts better and adds much more flavor.
• Baking Sheet or Oven-Safe Bowls: For toasting and broiling the cheese-topped baguette slices directly in the soup.

Each tool plays a role in building layers of flavor or enhancing texture—don’t skip them!

Preparation Tips

Take your time caramelizing the onions; this step is key to the soup’s signature flavor. Use medium-low heat and patience—rushing will lead to browning rather than caramelizing. Choose meaty, well-marbled short ribs for the richest broth. Don’t skimp on deglazing the pan after searing; those browned bits are liquid gold. And finally, use day-old crusty bread for the topping—it holds up better in the soup and gets the perfect crunch under the broiler.

Ingredients for this French Onion Beef Short Rib Soup

• 3 lbs bone-in beef short ribs
• 2 tablespoons olive oil
• Salt and freshly ground black pepper, to taste
• 4 large yellow onions, thinly sliced
• 4 garlic cloves, minced
• 2 tablespoons unsalted butter
• 1 tablespoon brown sugar (optional, to aid caramelization)
• 1/2 cup dry white wine (or red wine for deeper flavor)
• 8 cups beef broth (low sodium preferred)
• 2 tablespoons Worcestershire sauce
• 1 teaspoon fresh thyme leaves (or 1/2 tsp dried thyme)
• 2 bay leaves
• 1 tablespoon balsamic vinegar
• 1 French baguette, sliced into 1-inch rounds
• 2 cups Gruyère cheese, grated (Swiss cheese can substitute)
• Fresh parsley or chives for garnish (optional)

Step 1: Season and Sear the Short Ribs

Pat the beef short ribs dry with paper towels and season generously with salt and pepper. Heat olive oil in a Dutch oven over medium-high heat. Sear the short ribs on all sides until well-browned, about 3–4 minutes per side. Remove the ribs and set them aside.

---

Step 2: Caramelize the Onions

In the same pot, reduce heat to medium. Add butter and the sliced onions. Stir occasionally, allowing the onions to caramelize slowly for about 30–40 minutes. Add brown sugar halfway through for deeper color and sweetness. Stir in minced garlic during the last 2 minutes.

---

Step 3: Deglaze and Simmer

Pour in the wine to deglaze the pot, scraping up the browned bits from the bottom. Let it reduce by half, then add the beef broth, Worcestershire sauce, thyme, bay leaves, and the seared short ribs back to the pot. Bring to a boil, reduce heat to low, cover, and let simmer for 2.5 to 3 hours until the beef is tender and falling off the bone.

---

Step 4: Remove Ribs and Shred

Take the short ribs out of the soup and remove the bones. Shred the meat with two forks and discard any excess fat. Return the shredded beef to the pot. Stir in balsamic vinegar for a touch of acidity.

---

Step 5: Prepare the Bread Topping

While the soup simmers, preheat your oven to 375°F (190°C). Place baguette slices on a baking sheet, toast for 5–7 minutes, flip and toast the other side until golden. Sprinkle grated Gruyère on top and broil for 1–2 minutes until cheese is bubbly and lightly browned.

---

Step 6: Assemble and Serve

Ladle the hot soup into oven-safe bowls, top each with 2–3 cheesy baguette slices. Optional: place the entire bowl under the broiler for an extra-melty finish. Garnish with fresh herbs and serve immediately.

Notes

This soup is all about building flavor through slow cooking and quality ingredients. Using bone-in short ribs imparts a deeper, richer taste, while caramelizing the onions until deeply golden transforms their natural sugars into a complex sweetness. For extra depth, you can even roast the bones before adding them to the soup. Don’t be shy with the cheese—Gruyère not only adds a creamy, nutty profile but also creates that classic French onion soup crust that everyone loves.

Watch Out for These Mistakes While Cooking

• Rushing the onions: Caramelizing onions takes time. Turning up the heat to speed things along will only burn them or result in uneven flavor.
• Skipping the sear: Searing the beef short ribs properly locks in flavor and adds beautiful browning that enhances the entire broth.
• Underseasoning: With a long cook time, seasoning layers are important. Don’t forget to taste and adjust salt toward the end.
• Using pre-shredded cheese: Pre-shredded varieties often contain anti-caking agents, which affect melting. Always grate fresh cheese.
• Not removing bay leaves: They’re great for infusing flavor but should be taken out before serving.

Storage Instructions

Allow the soup to cool completely before storing. Transfer it into airtight containers and refrigerate for up to 4 days. The flavors deepen overnight, making it even better the next day. For longer storage, freeze without the bread topping for up to 3 months. Reheat gently on the stovetop, and always prepare fresh cheesy bread when serving leftovers.

Frequently Asked Questions

What’s the best cut of meat for this soup?

Bone-in short ribs are ideal due to their marbling and deep beefy flavor, but chuck roast can be used as a more affordable substitute.

Can I make this in a slow cooker?

Absolutely. After searing the beef and caramelizing the onions, transfer everything to a slow cooker and cook on low for 8 hours or until the meat is tender.

Is there a vegetarian version?

You can substitute mushrooms for beef and use vegetable broth. The flavor profile will change, but caramelized onions still deliver great taste.

What can I use instead of Gruyère cheese?

Swiss, Emmental, or even provolone can work in a pinch. Gruyère offers the best melt and flavor for this dish.

Can I prepare the soup in advance?

Yes! In fact, it tastes even better the next day. Just store it without the bread topping and reheat when ready to serve.

How thick should the soup be?

This is a brothy soup, but the collagen from the beef bones gives it some body. It shouldn’t be thick like stew but should have a rich mouthfeel.

Do I have to use wine?

No. You can use additional broth or a splash of balsamic vinegar or apple cider vinegar for acidity if you prefer to avoid alcohol.

Can I freeze this soup?

Yes, but freeze it without the bread and cheese topping. Thaw in the fridge overnight and reheat on the stove for best results.
