Bacon-Wrapped Water Chestnuts (Rumaki)
Crunchy, juicy water chestnuts marinated in a sweet and savory soy-ginger glaze, then wrapped in smoky bacon and broiled until irresistibly caramelized. A classic retro appetizer that's the first to vanish at any party.
For 8 servings
- prep · ~20 min
Soak the toothpicks.
Place 24 wooden toothpicks in a small bowl of water and let them soak for at least 20 minutes. This prevents them from scorching under the broiler.
TIPSoaking toothpicks in water is essential — dry toothpicks will char and may even catch fire. - mix · ~2 min
Make the marinade.
In a medium bowl, whisk together the soy sauce, brown sugar, grated ginger, minced garlic, and rice vinegar until the sugar mostly dissolves.
- prep · ~30 min
Marinate the water chestnuts.
Drain and rinse the water chestnuts. Pat them dry with paper towels. Add the water chestnuts to the marinade, toss to coat evenly, and let them sit for 30 minutes, stirring once halfway through.
TIPDrying the water chestnuts before marinating helps the bacon wrap stick and the glaze cling better. - assemble · ~10 min
Wrap the water chestnuts with bacon.
Preheat the broiler with a rack positioned about 6 inches from the heat source. Line a baking sheet with foil and place a wire rack on top. Remove the water chestnuts from the marinade, reserving the liquid. Wrap each water chestnut with a half-slice of bacon, secure with a soaked toothpick, and place seam-side down on the wire rack.
TIPStretching the bacon slightly before wrapping makes it cling tighter to the chestnut. - bake · ~14 min
Broil the rumaki.
Broil for 6-8 minutes, until the bacon is starting to crisp on top. Remove the tray, carefully flip each rumaki over, and brush with the reserved marinade. Return to the broiler for another 5-7 minutes until the bacon is fully crisp and the glaze is bubbly and caramelized.
TIPWatch closely the last two minutes — the sugar in the marinade can go from caramelized to burnt very quickly. - serve · ~3 min
Rest briefly and serve warm.
Let the rumaki cool on the rack for 2-3 minutes so the glaze sets. Transfer to a serving platter and serve warm.
TIPWarn guests about the toothpicks or remove them before serving for a cleaner presentation.
What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Pat the water chestnuts thoroughly dry before marinating to help the glaze cling and the bacon stay put.
- 2Stretch each bacon half-slice slightly before wrapping to ensure it clings snugly around the chestnut.
- 3Soak toothpicks for at least 20 minutes; dry toothpicks can char or catch fire under the broiler.
- 4Use a wire rack on the baking sheet so heat circulates under the rumaki, crisping the bacon evenly.
- 5Watch the rumaki closely during the final broiling minutes — the sugar in the marinade burns quickly.
- 6Let rumaki rest 2-3 minutes after broiling so the caramelized glaze sets before serving.
- 7For a cleaner presentation, remove toothpicks before plating and warn guests if left in.
