How to make Asian-style dumplings (gyoza/mandu) and freeze them for later cooking
Making Asian-style dumplings (gyoza or mandu) at home is a satisfying, hands-on project that yields tender wrappers and flavorful filling. This guide walks you through mixing a balanced filling, folding neat dumplings, freezing them properly, and cooking from frozen so you always have a tasty meal on hand.
Step 1: Gather ingredients and tools
Prepare 400 g ground pork or a vegetarian protein like finely chopped tofu, 200 g cabbage, 3 sliced green onions, 1 tablespoon grated ginger, 2 cloves minced garlic, 1 tablespoon soy sauce, 1 tablespoon sesame oil, 1 teaspoon salt, and about 40 round dumpling wrappers. Also have a large mixing bowl, a cutting board, a small water bowl, baking sheet, parchment paper, and a clean towel. Having everything arranged speeds assembly and keeps filling cold.

Step 2: Prepare and salt the cabbage
Finely shred 200 g cabbage and toss with 1 teaspoon salt in a bowl. Let sit 10 minutes to draw out excess moisture, then squeeze firmly in a kitchen towel or between hands to remove about 30–40% of the liquid. Removing moisture keeps the filling from becoming soggy and helps the dumplings hold together.

Step 3: Mix the filling thoroughly
Combine the drained cabbage with 400 g ground pork (or 350 g firm tofu), 3 sliced green onions, 1 tbsp grated ginger, 2 minced garlic cloves, 1 tbsp soy sauce, 1 tbsp sesame oil, and 1/2 teaspoon white pepper in a bowl. Mix with a spoon or by hand for 2–3 minutes until the mixture is cohesive and slightly sticky; this texture helps the filling bind inside the wrapper.

Step 4: Portion and place filling on wrappers
Set out wrappers on a lightly floured surface. Place about 1 teaspoon to 1 tablespoon (depending on wrapper size) of filling in the center of each wrapper—enough to fill but not overstuff. Keep unused wrappers covered with a damp towel to prevent drying; consistent portioning makes folding quicker and yields evenly cooked dumplings.

Step 5: Fold and seal each dumpling
Dip finger in water and moisten the wrapper edge, then fold and pleat to seal, pressing firmly to remove air pockets. Aim for 10–12 pleats or a simple half-moon seal; each dumpling should be about 5–6 cm wide. Proper sealing prevents leaks during cooking and freezing.

Step 6: Flash-freeze dumplings on a tray
Arrange dumplings in a single layer on a parchment-lined baking sheet with at least 1 cm space between them. Freeze uncovered for 1–2 hours until firm (flash-freeze), which prevents them from sticking together in storage. Once firm, transfer to airtight freezer bags or containers, label with date, and remove excess air.

Step 7: Cook from frozen or thaw wisely
To pan-fry: heat 1 tbsp oil in a nonstick skillet, arrange frozen dumplings flat-side down, brown 2–3 minutes, add 120 ml water and cover to steam 6–8 minutes until water evaporates, then uncover and crisp 1–2 minutes. To boil: drop frozen dumplings into boiling water and cook 6–8 minutes until they float and filling is hot. To steam: steam 8–10 minutes from frozen. Always cook from frozen to avoid soggy wrappers and ensure even reheating.

- Use a food processor to finely chop cabbage fast if you prefer a finer texture.
- If using tofu, press it 15–30 minutes to remove moisture before crumbling into the filling.
- Freeze for no more than 2–3 months for best flavor and texture; label bags with the date.
- Lightly dust wrappers with cornstarch if they are very sticky to handle.
- Make extra filling and freeze it in 200 g portions to assemble fresh dumplings later.
- Serve with a simple dipping sauce: 1 tbsp soy sauce, 1 tsp rice vinegar, a few drops sesame oil, and a pinch of chili flakes.
- Do not refreeze dumplings that have been thawed after cooking; only freeze before cooking once.
- Ensure meat filling reaches a safe internal temperature (pork at 71°C/160°F) when reheating from frozen.
- Avoid overfilling wrappers; burst dumplings can leak juices into the cooking pan.
- Keep raw meat filling chilled while assembling to prevent bacterial growth and discard any filling left at room temperature for more than 2 hours.
