Ingredients You’ll Need

This recipe is all about simple, high-quality ingredients working in harmony to build layers of flavor and texture. Each component serves a purpose, from the caramelized onions bringing sweetness and body, to the short ribs adding meaty richness, and the Gruyère topping delivering a perfectly melty finish.

• 2 lbs beef short ribs: Choose meaty ribs with good marbling to ensure tender, flavorful bites after slow cooking.
• 3 large yellow onions, thinly sliced: Key to that signature French onion sweetness and golden color when caramelized.
• 6 cups beef broth (preferably homemade): The rich base that melds all the flavors together — homemade is best but store-bought works in a pinch.
• 2 tsp fresh thyme leaves: Adds a subtle herbal note that brightens and complements the beef perfectly.
• 2 bay leaves: Infuses the broth with a gentle woodsy aroma and depth.
• 4 slices sourdough bread: Sturdy and tangy, these become irresistible croutons topped with gooey cheese.
• 1 cup Gruyère cheese, shredded: The crowning glory melted on top, adding a nutty, creamy layer to the soup.
• 2 tbsp unsalted butter: Essential for achieving perfectly caramelized onions without bitterness.
• Salt and pepper to taste: To balance flavors and bring out the best in every ingredient.

How to Make French Onion Beef Short Rib Soup

Step 1: Caramelize the Onions

Begin by melting the butter in a large pot over medium heat, then add the thinly sliced onions. Patience is your best friend here—slowly cook the onions for about 30 minutes until they transform into a deep golden brown with rich, sweet flavors. This stage is crucial because those beautifully caramelized onions provide the characteristic depth and sweetness that make French onion dishes so special.

Step 2: Sear the Beef Short Ribs

Once the onions are ready, push them to the side of the pot and add your beef short ribs. Sear them on all sides for around 5 to 7 minutes until a beautiful brown crust forms. This browning step locks in the juices and adds a smoky, savory dimension that will elevate your French Onion Beef Short Rib Soup to irresistibly delicious heights.

Step 3: Simmer with Broth and Herbs

Pour in the beef broth, then toss in the fresh thyme leaves and bay leaves. Bring everything to a gentle boil before reducing the heat to a simmer. Let the soup cook uncovered for about 2 hours, allowing the flavors to meld and the short ribs to become fall-apart tender. The broth will intensify into a rich, aromatic base that’s packed with the essence of slow-cooked beef and sweet onions.

Step 4: Prepare for Baking

Preheat your oven to 350°F (175°C). Ladle the soup into oven-safe bowls, making sure each gets a generous amount of tender short ribs and onions. Top each bowl with a slice of sourdough bread and a hearty sprinkle of shredded Gruyère cheese. The bread will soak up the luscious broth, while the cheese melts into a gooey, golden crust during baking.

Step 5: Bake Until Bubbly and Perfect

Pop the bowls into the oven and bake for 15 to 20 minutes until the cheese is bubbly and lightly golden. This final step adds that irresistible texture contrast and cheesy richness, transforming your French Onion Beef Short Rib Soup into a warm, comforting masterpiece.

Garnishes

For the perfect presentation and an extra pop of freshness, sprinkle a few fresh thyme leaves or finely chopped parsley over the cheese topping after baking. A light drizzle of good quality olive oil can also add a subtle silky finish that complements the robust flavors.

Side Dishes

Pair this hearty soup with a simple green salad dressed lightly with lemon vinaigrette to balance the richness. Roasted root vegetables or a crisp baguette on the side also make fantastic companions that enhance the meal without overshadowing the star – the soup itself.

Creative Ways to Present

Try serving the soup in mini cast iron cocottes for an intimate and charming rustic feel. Alternatively, create a DIY French onion soup bar by setting out toppings like different cheeses, toasted baguette slices, or crispy prosciutto to let guests customize their bowls. It’s a fun way to make the experience interactive and memorable!

Make Ahead and Storage

Storing Leftovers

Allow the soup to cool completely before transferring it to airtight containers. Stored in the refrigerator, your French Onion Beef Short Rib Soup will remain delicious for up to 3 days, with the flavors often tasting even better the next day as they continue to meld.

Freezing

This soup freezes wonderfully. Remove the guarnishes and bread, then place the cooled soup in freezer-safe containers. It can be frozen for up to 3 months. When you’re ready, thaw it overnight in the fridge and reheat gently on the stovetop.

Reheating

Warm your soup slowly over medium-low heat to prevent the broth from becoming cloudy or separating. Add the bread and cheese topping fresh before baking or broiling just until bubbly to recapture that delightful texture and gooey finish.

FAQs

Can I use other cuts of beef instead of short ribs?

While short ribs provide incredible richness and tenderness thanks to their marbling, you can substitute with beef chuck roast cut into chunks. Just keep in mind the texture and cooking time may vary slightly, but you’ll still get a deeply flavorful soup.

Is it possible to make this soup vegetarian?

This recipe’s heart is the beef short ribs and beef broth, so for a vegetarian version, try substituting with a hearty mushroom broth and adding caramelized onions with sautéed mushrooms for umami depth. Though it won’t be French Onion Beef Short Rib Soup anymore, it will still be delicious.

What is the best cheese to use on top?

Gruyère is classic for French onion dishes due to its melting qualities and nutty flavor. Alternatively, Comté or Emmental also work beautifully, but avoid cheeses that don’t melt well or overpower the delicate balance of the soup.

Can I make this soup in a slow cooker?

Absolutely! After caramelizing onions and searing the ribs on the stove, transfer everything to a slow cooker, add broth and herbs, and cook on low for 6-8 hours. You’ll get tender meat and deep flavors with less hands-on time.

How do I get the onions to caramelize properly?

Patience is key. Cook the onions on medium heat with butter, stirring occasionally, for at least 30 minutes. Avoid rushing by increasing the heat, as that can cause burning instead of proper caramelization. The transformation into golden sweet onions is what makes your French Onion Beef Short Rib Soup sing.
