Ingredients

For the Main Dish:

3 lbs beef short ribs, bone-in
4 large yellow onions, thinly sliced
4 tbsp unsalted butter
2 tbsp olive oil
6 cups beef broth (preferably low sodium)
1 cup dry white wine
2 tsp fresh thyme leaves (or 1 tsp dried)
2 bay leaves
1 tbsp Worcestershire sauce
Salt and freshly ground black pepper, to taste

For the Gruyère Bread Topping:

1 baguette, sliced into ½-inch rounds
8 oz Gruyère cheese, grated
1 garlic clove, halved (for rubbing on bread)
Optional: fresh thyme for garnish

How I Make It

Step 1:

Preheat your oven to 325°F.

Step 2:

Reduce heat to medium and melt the butter in the same pot. Add the sliced onions and cook slowly, stirring frequently, for about 45 minutes until deeply golden and caramelized. This part takes patience, but those sweet, jammy onions are *everything* for this soup.

Step 3:

Deglaze the pot with the white wine, scraping up all those tasty browned bits stuck on the bottom. Let it reduce for a couple of minutes, then add the beef broth, thyme, bay leaves, and Worcestershire sauce. Return the ribs to the pot, nestling them in the liquid.

Step 4:

Cover the pot and place it in the oven. Braise for about 2½ to 3 hours, until the ribs are fork-tender and the meat easily pulls away from the bone. Once done, carefully remove the ribs and shred the meat, discarding bones and excess fat. Return the shredded meat to the soup.

Step 5:

While the stew is finishing, prepare the Gruyère bread. Preheat your broiler. Lightly toast the baguette slices, then rub each with the cut side of the garlic clove while still warm. Pile on a generous amount of grated Gruyère cheese.

Step 6:

Ladle the hot soup into oven-safe bowls. Place a cheesy bread slice on top of each bowl and broil for 2-3 minutes until the cheese melts, bubbles, and turns golden brown. Watch closely so it doesn’t burn! Garnish with a sprinkle of fresh thyme and serve immediately.

Variations & Tips

For a richer broth, add a splash of brandy or cognac when deglazing.
If short ribs aren’t available, chuck roast or beef shanks work well too.
Use a good-quality beef broth for depth, or make your own if you have time.
Caramelize the onions low and slow—don’t rush this step or the soup will lack sweetness.
Switch up the cheese topping with Comté or Emmental if you prefer a milder flavor.
To save time, cook the ribs a day ahead and reheat with the soup; flavors meld beautifully overnight.

How I Like to Serve It

This soup is a perfect date night or weekend meal, especially when paired with a crisp green salad and a bold red wine. I also love serving it at holiday dinners for that cozy “wow” factor without fuss. When it’s chilly outside, this warm, cheesy soup feels like a big hug in a bowl!

Notes

Store leftovers covered in the fridge for up to 3 days. Reheat gently on the stovetop to preserve texture.
If reheating, you can refresh the cheese bread by broiling again until bubbly.

Closing: Once you get a taste of that tender beef, caramelized onion broth, and golden Gruyère crown, you’ll understand why this recipe becomes your go-to comfort classic every time.
