What Makes This Soup Special

French onion soup has existed for centuries and is best known for its sweet caramelized onions and cheesy bread topping. Adding short ribs transforms it into a deeper, fuller, more satisfying dish. Slow-braising the meat enriches the broth, making it thicker, silkier, and more complex.

Here’s what sets this version apart:

Deep caramelization

The onions cook for almost an hour, developing sweetness and a jam-like texture. This slow process creates the soup’s signature flavor.

Fall-apart tender short ribs

Beef short ribs release collagen during braising, which naturally thickens the broth and infuses it with richness.

Layered flavors

Wine, broth, herbs, and aromatics combine to create a balanced profile that isn’t too salty or too sweet.

Gruyère toast

Instead of broiling the cheese directly over the soup, this version places gruyère toast on top when serving—making it easier to control texture and avoid soggy bread.

A perfect blend of rustic and refined

While the recipe involves slow-cooking, it is simple to follow and rewards patience with incredible flavor.

Ingredients for the Soup

In french onion short rib soup with gruyère toast, each ingredient plays a specific role. Choosing the right type of onions, cheese, and meat makes all the difference.

Onions

Yellow onions work best because they caramelize evenly and bring sweetness without overpowering the dish. You can mix a small amount of red or white onions, but yellow should remain the base.

Beef short ribs

Bone-in short ribs provide the best flavor. As they cook, the bones contribute richness and body to the broth. Boneless ribs are an option, but the final result will be slightly less full-bodied.

Wine

A dry white wine helps lift the sweetness of the onions and balances the richness of the beef. Red wine can also be used for a deeper, earthier flavor.

Broth

Beef broth is traditional, but a mix of beef and vegetable broth creates a smoother flavor that doesn’t overshadow the onions.

Herbs

Fresh thyme and bay leaves add aroma without overwhelming the soup’s natural sweetness.

Cheese

Gruyère is the classic choice. It melts evenly, browns beautifully, and has a nutty flavor that pairs well with the onions and beef.

Step-by-Step: How to Make French Onion Short Rib Soup with Gruyère Toast

Preparing the Short Ribs

Seasoning the meat

Seasoning generously at the beginning ensures that flavor penetrates the beef as it cooks. Salt, pepper, and a light dusting of flour help create a golden crust when searing.

Searing the short ribs

High heat is essential. Browning creates caramelized bits at the bottom of the pot, which enrich the broth later.

Braising process

The short ribs simmer gently with broth, herbs, and aromatics until they become soft enough to fall apart. This step forms the foundation of the soup.

Caramelizing the Onions

Low and slow method

Onions need time. They should cook on medium-low heat, stirring frequently until they turn deep golden brown.

Deglazing

Wine helps lift the caramelized bits from the pan, intensifying flavor and giving the soup a beautiful color.

Combining the Soup

Adding broth and aromatics

After the onions are ready, the braised beef (shredded or whole) and the reduced braising liquid are added back to the pot.

Slow simmer

Letting the soup simmer for at least 30 minutes helps all the flavors blend naturally.

Adjusting seasoning

Taste at the end—not earlier. The broth reduces as it cooks, so seasoning too soon may result in an overly salty soup.

Making the Gruyère Toast

Choosing the right bread

Baguette slices work well, but rustic country bread provides a sturdier base and absorbs the soup beautifully without falling apart.

Layering the cheese

The cheese should fully cover the bread to ensure a bubbly, golden surface after broiling.

Toasting method

Broil until the cheese melts and becomes lightly crisp at the edges.

Serving the Dish

Serving french onion short rib soup with gruyère toast is all about balance.

Soup first, toast on top

Place the gruyère toast over the soup after ladling it into bowls to keep the cheese crisp.

Add fresh herbs or cracked pepper

A sprinkle of thyme leaves or black pepper adds freshness and visual appeal.

Proper serving bowls

Use deep, heat-safe bowls to keep the soup warm longer.

Helpful Tips for Success

Allow enough time for caramelization

Rushing the onions leads to a less flavorful soup. They need at least 45 minutes.

Don’t skip searing the ribs

This step builds the foundation of flavor.

Use homemade broth if possible

It results in a more natural, rich, and balanced soup.

Taste before serving

Adjusting seasoning at the end ensures the most accurate flavor.

Variations

Mushroom-enhanced version

Add sautéed mushrooms for a richer, earthier profile.

No-wine version

Replace wine with extra broth and a splash of apple cider vinegar for balance.

Spiced version

Add a pinch of smoked paprika for warmth.

Vegetarian-inspired version

Replace ribs with roasted mushrooms and use vegetable stock (the dish will lose its original identity but gains a comforting, earthy twist).

Storage and Reheating

Storing

Refrigerate the soup (without the toast) for up to 4 days. The flavor deepens over time.

Freezing

Freeze in airtight containers for up to 3 months. Thaw overnight in the refrigerator before reheating.

Reheating

Warm on the stovetop over medium heat. Prepare fresh gruyère toast each time for best texture.

Serving Suggestions

Serve the soup with:

  • A small green salad with lemon dressing
  • Roasted vegetables
  • Simple garlic-rubbed bread
  • A refreshing drink like mint iced tea

Ingredients

For the Short Ribs & Broth

For the French Onion Soup Base

For the Gruyère Toast

Instructions

Sear the Short Ribs

  1. Pat the short ribs dry and season with salt and pepper. Heat olive oil in a heavy pot over medium-high heat. Sear the ribs on all sides until deep brown, about 8–10 minutes. Remove and set aside.

Build the Broth

  1. In the same pot, add chopped carrot, celery, onion, and garlic. Cook until slightly softened. Stir in tomato paste and cook 1 minute. Add bay leaf, thyme, and beef broth. Return the short ribs to the pot, cover, and simmer gently for 2 hours until the meat is tender and falling off the bone.

Shred the Meat

  1. Remove the ribs and let them cool slightly. Shred the meat, discarding bones and excess fat. Strain the broth to remove vegetables and herbs. Set broth aside.

Caramelize the Onions

  1. In a clean large pot, heat olive oil and butter. Add sliced onions, salt, sugar, and black pepper. Cook over medium-low heat for 35–45 minutes, stirring often, until the onions turn deep golden brown and jammy.

Build the French Onion Base

  1. Sprinkle flour over the onions and stir for 1 minute. Add balsamic vinegar and deglaze. Pour in non-alcoholic cooking wine or extra broth. Let it simmer for 5 minutes so everything blends.

Combine the Soup

  1. Add the strained beef broth and shredded short rib meat into the caramelized onion base. Simmer for 20 minutes, allowing the flavors to merge into a rich, hearty soup.

Make the Gruyère Toast

  1. Heat oven to 180°C. Brush bread slices with olive oil and rub lightly with garlic. Top with grated Gruyère and bake for 8–10 minutes until melted, golden, and bubbly.

Serve

  1. Ladle the hot French onion short rib soup into bowls. Place a Gruyère toast on top — or on the side — and enjoy this warm, comforting dish.

Note

For a deeper flavor, caramelize onions slowly — don’t rush them.

You can prepare the short rib broth a day ahead for easier fat removal.

Substitute Gruyère with Emmental or mozzarella if preferred.

Leftovers keep well refrigerated for 3–4 days.

Freeze without the cheese toast for up to 2 months.
