French Onion Soup Dumplings

The Ultimate Guide to French Onion Soup Dumplings: A Fusion Masterpiece


  • Author: David Andersson
  • Total Time: 1 hour
  • Yield: 20 dumplings 1x

Description

At its core, the French Onion Soup Dumplings recipe is a creative take on the Chinese Xiao Long Bao, or soup dumpling. Traditionally, Xiao Long Bao is filled with pork and a gelatinized broth that melts into a hot liquid when steamed. This version replaces the traditional pork filling with the iconic components of French onion soup: slowly caramelized onions, rich beef stock, and nutty Gruyere cheese.


Ingredients

Scale

For the filling:

  • 2 large onions (thinly sliced)
  • 2 tbsp butter
  • 1 tbsp olive oil
  • 2 cloves garlic (minced)
  • 1 tsp sugar
  • ½ tsp salt
  • ½ cup beef broth
  • 1 tsp fresh thyme (or ½ tsp dried)
  • ½ cup shredded Gruyère cheese (or Swiss)

For the soup gelatin (key step!):

  • 1 cup beef broth
  • 1½ tsp gelatin powder

For the dumplings:

  • Round dumpling wrappers (store-bought or homemade)

Instructions

🥣 Step 1: Make the Soup Gelatin

  1. Heat 1 cup beef broth until warm (not boiling).
  2. Sprinkle gelatin over it and stir until dissolved.
  3. Pour into a shallow dish and refrigerate ~1 hour until firm.
  4. Cut into small cubes.

👉 This is what melts inside and creates the “soup” effect.


🍳 Step 2: Caramelize the Onions

  1. Heat butter + olive oil in a pan over medium-low heat.
  2. Add onions, sugar, and salt.
  3. Cook slowly (25–30 min), stirring often, until deep golden brown.
  4. Add garlic and cook 1–2 min more.
  5. Pour in ½ cup broth and thyme; simmer until most liquid is gone.
  6. Let cool completely.

🥟 Step 3: Make the Filling

  • Mix caramelized onions with cheese.
  • Gently fold in the gelatin cubes.

🥟 Step 4: Assemble Dumplings

  1. Place 1 wrapper in your palm.
  2. Add about 1 tbsp filling.
  3. Pleat and seal tightly (important to prevent leaks).

♨️ Step 5: Steam

  1. Line a steamer with parchment or cabbage leaves.
  2. Place dumplings spaced apart.
  3. Steam for 8–10 minutes.

Notes

The key to this dish is patience—slowly caramelized onions and a well-set broth gelatin create that signature burst of soup inside each dumpling.
