Ingredients

For the Caramelized Onions

  • 3 large yellow onions, thinly sliced
  • 2 tbsp unsalted butter
  • 2 tbsp olive oil
  • 1/2 tsp salt
  • 1/2 tsp freshly ground black pepper
  • 1 tsp sugar
  • 2 tsp fresh thyme leaves (or 1 tsp dried)
  • 2 tbsp dry sherry or white wine
  • 1 tsp balsamic vinegar

For the Dumplings

  • 24 round dumpling wrappers (gyoza or wonton style)
  • 1 cup Gruyère cheese, finely grated
  • 1/4 cup Parmesan cheese, grated
  • 2 tbsp fresh chives, finely chopped
  • 1 egg, lightly beaten (for sealing)
  • Vegetable oil, for frying

For the Broth Drizzle

  • 1/2 cup rich vegetable or beef broth
  • 1 tbsp unsalted butter
  • 1/2 tsp Worcestershire sauce
  • Salt and pepper, to taste

Instructions

1. Prepare the caramelized onions
Heat butter and olive oil in a large skillet over medium heat. Add onions, salt, and pepper. Cook, stirring often, until onions soften (about 10 minutes). Sprinkle in sugar and thyme. Continue cooking on low, stirring frequently, until onions are deep golden brown (15–20 minutes more). Add sherry (or wine) and balsamic vinegar; cook 2–3 minutes until liquid evaporates. Remove from heat and cool.
2. Assemble the dumplings
Place a dumpling wrapper on a clean surface. Add 1 heaping teaspoon of caramelized onion in the center. Top with a small pinch of Gruyère, Parmesan, and chives. Brush edges with beaten egg, fold and pleat to seal into a half-moon or purse shape. Repeat with remaining wrappers and filling.
3. Cook the dumplings
Heat a thin layer of oil in a large nonstick skillet over medium-high heat. Add dumplings in a single layer without crowding. Fry until bottoms are golden (2–3 minutes). Add 1/4 cup water, cover immediately, and steam for 3–4 minutes until wrappers are tender. Remove lid and cook until bottoms crisp again, about 1 minute. Transfer to a platter.
4. Prepare the broth drizzle
In a small saucepan, heat broth, butter, and Worcestershire sauce until butter melts. Season with salt and pepper. Drizzle a small spoonful over each dumpling before serving or serve on the side for dipping.

Zusatztipps für die Zubereitung

To ensure success, use a large skillet for the onions and a dedicated nonstick frying pan with a tight-fitting lid for the dumplings. A dumpling press can help with consistent shaping, but your hands work just as well for authentic pleating. Use a slotted spoon when moving the dumplings to prevent excess oil from reaching the serving platter.

Varianten und Anpassungen

You can easily customize these dumplings to fit dietary needs. For a vegan version, substitute the butter and cheese with plant-based alternatives and use an egg replacer or water for sealing the wrappers. If you cannot find Gruyère, Swiss or Emmental cheese are excellent substitutes. For those with gluten sensitivities, look for certified gluten-free dumpling wrappers.

Steps

Step 01

Caramelize the onions: Heat butter and olive oil in a large skillet over medium heat. Add sliced onions, salt, and pepper, stirring often until softened, approximately 10 minutes. Sprinkle in sugar and thyme, continuing to cook on low heat while stirring frequently until onions achieve a deep golden brown color, 15 to 20 minutes longer. Pour in sherry or wine and balsamic vinegar, cooking for 2 to 3 minutes until liquid evaporates completely. Remove from heat and allow to cool.

Step 02

Assemble the dumplings: Place each dumpling wrapper on a clean surface. Add 1 heaping teaspoon of caramelized onion filling in the center, topping with a small pinch of Gruyère cheese, Parmesan cheese, and fresh chives. Brush the wrapper edges with beaten egg and fold into a half-moon or purse shape, pleating to seal securely. Repeat with all remaining wrappers and filling.

Step 03

Pan-fry and steam the dumplings: Heat a thin layer of vegetable oil in a large nonstick skillet over medium-high heat. Arrange dumplings in a single layer without crowding and fry until bottoms are golden brown, 2 to 3 minutes. Add 1/4 cup water, cover immediately, and steam for 3 to 4 minutes until wrappers become tender. Remove the lid and cook for 1 minute more until bottoms crisp again. Transfer to a serving platter.

Step 04

Prepare the broth drizzle: In a small saucepan, heat broth, butter, and Worcestershire sauce over medium heat until butter melts completely. Season with salt and pepper to taste. Drizzle a small spoonful over each dumpling before serving or offer on the side for dipping.
