An extraordinary appetizer that encapsulates all the rich, comforting flavors of a classic bowl of French Onion Soup into a single, perfect bite. Each dumpling holds a savory, molten core of deeply caramelized onion and rich beef broth, which bursts forth upon biting. Pan-fried for a crispy bottom and topped with a glorious crown of broiled Gruyère cheese, this is the ultimate comfort food fusion.
This recipe is the culmination of a dream: to capture the soul of my favorite soup in a new and unexpected form. How could one possibly get the savory broth, the sweet jammy onions, and the iconic cheesy crouton into one little package? The answer lies in a brilliant technique borrowed from the masters of the soup dumpling, Xiao Long Bao. The secret is creating a "solid" broth.
We achieve this by making a hyper-concentrated, deeply flavorful stock from slow-caramelized onions, sherry, brandy, and rich beef broth, then setting it with gelatin. When chilled, this magical concoction becomes firm, allowing it to be diced and easily wrapped in a delicate dumpling skin. When the dumpling is steamed, the gelatin melts, reverting to the luscious, savory soup that awaits inside.
But we don't stop there. A French Onion Soup experience isn't complete without the crispy, cheesy top. So, after the dumplings are pan-fried and steamed to perfection, we crown them with a generous blanket of nutty Gruyère cheese and slide them under the broiler until bubbly, golden, and irresistible. The result is a multi-layered textural experience: the gooey, melted cheese gives way to the soft, steamed dumpling wrapper, which encases the molten soup, all supported by a satisfyingly crispy pan-fried bottom. It’s a labor of love, but the final result is a culinary masterpiece that is truly unforgettable.
Recipe
Yields: About 24 dumplings Prep time: 45 minutes (plus 4-6 hours chilling time) Cook time: 30 minutes
Ingredients:
For the Gelatinized Soup Filling:
2 tablespoons unsalted butter
2 large yellow onions, very thinly sliced
½ teaspoon salt
1 teaspoon sugar
¼ cup dry sherry
2 tablespoons brandy
2 cups high-quality, rich beef broth
1 tablespoon unflavored gelatin powder
2 sprigs fresh thyme
For the Dumplings & Topping:
1 package (approx. 24) round dumpling wrappers
1 tablespoon neutral oil (like canola or grapeseed)
1 cup shredded Gruyère cheese
Fresh thyme leaves for garnish
Process/Steps:
Caramelize the Onions (Patience is Key): In a large, heavy-bottomed skillet or Dutch oven, melt the butter over medium-low heat. Add the sliced onions, salt, and sugar. Cook slowly, stirring every 5-10 minutes, for 30-40 minutes. The onions should become deeply browned, very soft, and jam-like. Do not rush this step.
Deglaze and Create the Soup Base: Increase the heat to medium-high. Pour in the sherry and brandy to deglaze the pan, scraping up all the flavorful browned bits from the bottom. Let the alcohol cook off for about 2 minutes. Add the beef broth and thyme sprigs. Bring to a simmer.
Set the Soup: In a small bowl, sprinkle the gelatin powder over 2 tablespoons of cold water and let it bloom for 5 minutes. Whisk the bloomed gelatin into the hot soup base until it is completely dissolved. Remove the thyme sprigs.
Chill the Filling: Pour the soup mixture into a shallow dish (an 8x8 inch baking dish is perfect). Let it cool to room temperature, then cover and refrigerate for at least 4 hours, or overnight, until completely firm and gelatinous.
Assemble the Dumplings: Once the filling is firm, use a knife to cut it into small ½-inch cubes. Place a dumpling wrapper on your work surface. Place one cube of the gelatinous filling in the center. Moisten the edges of the wrapper with a finger dipped in water. Fold and pleat the wrapper to seal the filling inside, creating a classic dumpling shape. Repeat with the remaining wrappers and filling.Pan-Fry and Steam: Heat the neutral oil in a large, non-stick, oven-safe skillet over medium-
high heat. Place the dumplings in the skillet, flat-side down, without overcrowding. Fry for 2-3 minutes, until the bottoms are golden brown and crisp. Without draining the pan, carefully pour in ½ cup of water. It will sizzle and steam aggressively. Immediately cover the skillet with a tight-fitting lid, reduce the heat to medium, and let the dumplings steam for 5-6 minutes.Add the Cheese Cap: Preheat your oven's broiler to high. Once the dumplings are steamed, remove the lid and let any remaining water evaporate. Turn off the heat. Sprinkle the shredded Gruyère cheese evenly over the top of the dumplings in the skillet.
Broil and Serve: Carefully transfer the entire skillet to the oven. Broil for 2-3 minutes, watching very closely, until the cheese is melted, bubbly, and beginning to brown in spots. Carefully remove the hot skillet from the oven. Garnish with a few fresh thyme leaves and serve immediately.
