How to cook water chestnuts

Water chestnuts can be cooked in a variety of ways, including boiling, grilling, roasting, stir-frying, and even microwaving. It is important not to overcook water chestnuts in order to preserve their crunchy texture, which is one of their main attractions in various dishes.
Before cooking fresh water chestnuts, they must be prepared by removing the dark shell. This can be done by cutting off the top and bottom of the chestnuts and using a vegetable peeler to remove the skin. The chestnuts should then be rinsed in cold water before cooking.

The three best ways to cook water chestnuts

  1. Roast the water chestnuts: Slice the peeled water chestnuts into 1/4-inch thick slices. Drizzle with olive oil, sprinkle with salt and pepper, and mix well to coat the slices evenly. Spread the slices in a single layer on a baking sheet and roast for 15 minutes, stirring occasionally for even cooking. Roasted water chestnuts can be served as an appetizer or as a side dish with roasted meats or soups.
  2. Stir-fry water chestnuts: Start by sautéing the garlic in a pan. Add sliced carrots and other vegetables, such as sugar snap peas, if desired. When the carrots are slightly softened, add the sliced water chestnuts and stir-fry for 2-3 minutes. Season with salt and continue stirring until all ingredients are cooked.
  3. Broiling water chestnuts: Water chestnuts go well with bacon. Preheat the oven to 350°F and cover a baking sheet with aluminum foil. Marinate peeled whole water chestnuts in soy sauce for one hour or overnight. Drain and roll in brown sugar. Wrap a slice of bacon around each chestnut and secure with toothpicks. Place the chestnuts on the rack and cook for 25-35 minutes, then broil for another 5 minutes, watching closely to prevent burning.

How to Cook Canned Water Chestnuts

Canned water chestnuts should be rinsed under cold water before cooking to remove any unpleasant tinny taste from the can. Soaking them in a mixture of baking soda and water for about 10 minutes can also help eliminate the tinny taste. They can be eaten as is or used in a variety of dishes. One popular option is an Asian stir-fry. Preheat a skillet, saute garlic and ginger, add vegetables such as broccoli, bell peppers, and carrots, and finish with the chopped water chestnuts. Make a sauce with soy sauce, oyster sauce, and a little cornstarch mixed with water and add to the skillet. Stir until the sauce thickens and coats the ingredients evenly.
