• Yellow onions: Sliced thin, they’re patiently caramelized to bring out their natural, mellow sweetness.
• Garlic: Infuses the soup with aromatic depth, complementing both onions and beef.
• Beef broth: The foundation of the soup, it catches every ounce of rich flavor from the meat and onions.
• Balsamic vinegar: A splash brightens everything, balancing the savory-sweet notes with a gentle acidity.
• Fresh thyme: Earthy and fragrant—this herb is essential for that beloved French onion aroma.
• Bay leaf: Adds subtle, herbaceous notes as everything simmers together.

One of the best things about French Onion Beef Short Rib Soup is how versatile and forgiving it can be! There’s plenty of room to play—so you can adapt the recipe for your pantry, your preferences, or any dietary needs.

• Mushroom Boost: Sauté sliced mushrooms alongside the onions for earthier depth and added umami in every bite.

• Different Cheeses: Try sharp white cheddar, provolone, or even a blend for unique cheesy topping twists.
• Gluten-Free Version: Use your favorite gluten-free bread for the topping to keep the soup celiac-friendly without sacrificing any of the cozy vibes.

How to Make French Onion Beef Short Rib Soup

Step 1: Sear the Short Ribs

Start by heating olive oil in a large, heavy-bottomed pot over medium-high heat. Season the beef short ribs all over with salt and pepper, then carefully sear them for about 4-5 minutes per side, until a rich brown crust forms. This crucial step locks in flavor and builds the savory base for the entire soup. Once beautifully browned, remove the ribs and set them aside.

Step 2: Caramelize the Onions

In the same pot—don’t wipe it out!—add your thinly sliced onions. Cook them slowly over medium heat, stirring often and scraping the brown bits from the bottom, for a good 15-20 minutes. The goal? Deeply caramelized, golden onions with irresistible sweetness. Once they reach that point, stir in the minced garlic and cook for another 1-2 minutes until fragrant.

Step 3: Simmer the Soup

Return the seared short ribs to the pot with the onions and garlic. Pour in the beef broth and add the balsamic vinegar, fresh thyme, bay leaf, and more salt and pepper to taste. Bring everything to a gentle simmer and cover, letting it cook on low for 1½ to 2 hours. You’ll know it’s ready when the beef is fall-off-the-bone tender and every bit of the soup is deeply aromatic.

Step 4: Shred the Beef and Finish the Soup

Remove the short ribs from the pot and shred the meat with two forks, discarding any bones or extra fat. Return the juicy, shredded beef to the pot and stir to marry the flavors. Give the soup a final taste and adjust the seasoning as needed—if you like things a little brighter, a splash more vinegar works wonders!

Step 5: Broil the Cheese Toasts

Toast thick slices of French bread under the broiler until golden. Ladle the hot soup into oven-safe bowls, float a bread slice on each, and load them up with shredded Swiss or Gruyère. Carefully broil the bowls for 2-3 minutes—you want bubbling, golden cheese just begging you to break through the crust. Let cool very slightly, then dig in!

How to Serve French Onion Beef Short Rib Soup

Garnishes

A final scatter of fresh thyme leaves or a crack of black pepper brightens every bowl, while an extra grating of cheese just before serving is always welcome. If you want to impress, a drizzle of high-quality olive oil or a touch of crispy fried shallots can add another delicious dimension.

Side Dishes

French Onion Beef Short Rib Soup is a showstopper on its own, but it pairs beautifully with a fresh green salad tossed in a mustardy vinaigrette, roasted root vegetables, or even a simple platter of pickles and olives to cut through the richness. A glass of robust red wine doesn’t hurt either!

Creative Ways to Present

For a dinner party, ladle the soup into individual oven-safe crocks for that signature bubbling, golden cheese cap. Alternatively, host a “soup bar”—let guests top their own bowls with bread and cheese, then broil to their liking. Garnish with fresh herbs or edible flowers for a restaurant-style flourish.

Make Ahead and Storage

Storing Leftovers

Store leftover French Onion Beef Short Rib Soup (without the bread and cheese topping) in an airtight container in the refrigerator for up to four days. Wait to add the cheesy toasts until just before serving for the very best texture.

Freezing

This soup (again, minus the bread and cheese) freezes beautifully! Cool it completely, then store in freezer-safe containers for up to three months. Thaw overnight in the fridge and reheat gently before adding the toppings.

Reheating

Warm the soup gently on the stovetop until piping hot. If prepping the cheesy bread topping, broil fresh toasts directly over the soup in oven-safe bowls, or simply melt the cheese on the toasts separately and float them atop the reheated soup.
