Your Simple Ingredient Checklist
This recipe uses a handful of high-impact ingredients for its signature decadent flavor.
The Ingredient Lineup:
- 2 lbs of beef short ribs
- 3 large yellow onions, thinly sliced
- 2 tbsp unsalted butter
- 6 cups of high-quality beef broth
- 2 tsp fresh thyme leaves
- 2 bay leaves
- 4 thick slices of sourdough bread
- 1 cup of shredded Gruyère cheese
- Salt and pepper to taste
Step-by-Step Instructions
The secret to this dish is taking the time to properly caramelize the onions and simmer the beef.
Part 1: Build the Flavor Base
- Caramelize the Onions: In a large Dutch oven or heavy-bottomed pot, melt the butter over medium heat. Add the thinly sliced onions and a pinch of salt. Cook slowly, stirring occasionally, for about 30 minutes, until the onions are deeply golden brown, soft, and sweet.
- Sear the Short Ribs: Push the caramelized onions to one side of the pot. Season the beef short ribs with salt and pepper. Add them to the empty side of the pot and sear on all sides until nicely browned, about 5-7 minutes total.
Part 2: Simmer the Soup
- Combine and Simmer: Pour in the beef broth. Add the fresh thyme leaves and the bay leaves. Stir everything together, scraping up any flavorful browned bits from the bottom of the pot.
- Slow Cook: Bring the soup to a gentle boil, then reduce the heat to a low simmer. Let the soup simmer, uncovered, for about 2 hours, or until the beef short ribs are fall-apart tender.
Part 3: The Cheesy Finish
- Prepare for Broiling: Preheat your oven to 350°F (175°C). Remove the bay leaves from the soup. Ladle the hot soup into four oven-safe bowls.
- Top and Bake: Place one slice of sourdough bread on top of the soup in each bowl. Generously sprinkle the shredded Gruyère cheese over the bread.
- Bake to Perfection: Carefully place the bowls on a baking sheet and bake for 15-20 minutes, or until the cheese is completely melted, bubbly, and beautifully golden brown. Serve immediately.
Frequently Asked Questions (FAQ)
1. What is the secret to getting perfectly caramelized onions? The key is low heat and patience. Don’t rush the process! Cooking the onions slowly over a longer period (30 minutes is great) allows their natural sugars to release and caramelize, which is what creates that deep, sweet, and savory flavor that is the signature of French onion soup.
2. Can I use a different cut of beef for this recipe? While beef short ribs provide a wonderfully rich and unctuous result due to their marbling, you could substitute them with beef chuck roast cut into large, 2-inch cubes. You would follow the recipe as directed, ensuring the beef is simmered until it is fall-apart tender.
3. What kind of cheese is best for French Onion Soup? Gruyère is the classic and best choice for its nutty, slightly sweet, and fantastic melting properties. However, if you can’t find it, you could substitute it with a mix of Swiss cheese and a little provolone or even a white cheddar.
4. Can I make this soup ahead of time? Yes, this soup is a great make-ahead meal! You can prepare the soup completely (through the simmering step) and store it in an airtight container in the refrigerator for up to 3 days. When you’re ready to serve, simply reheat the soup on the stovetop, ladle it into oven-safe bowls, and then proceed with the bread and cheese topping step.
