1Place red potato cubes into a large saucepan, cover with water, and bring to a boil. Cook potatoes over medium-low heat until tender, about 15 minutes; drain well.
2Place chopped cabbage into a saucepan and cover with water; bring to a boil. Reduce heat to medium-low and simmer the cabbage until tender and softened, about 15 minutes; drain well.
3Preheat the oven to 375 degrees F (190 degrees C).
4Spray a 9x13-inch baking dish with cooking spray.
5Lightly toss potatoes, cabbage, corned beef, and Swiss cheese in a large bowl until well combined.
6Stir together mustard, white wine, garlic powder, and black pepper in a bowl until smooth; mix into corned beef mixture.
7Spread the mixture into the prepared baking dish.
8Lay a phyllo sheet onto a work surface and spray with cooking spray. Place the phyllo sheet onto the casserole, folding the overhang back over the dish; spray the dry side of the overhang with more cooking spray.
9Repeat three more times, spraying, folding, and respraying the phyllo sheet each time.
10Brush the top of last sheet with melted butter.
11Bake in the preheated oven until phyllo sheets are crisp and browned and the casserole is hot, 45 to 55 minutes.
Footnotes
Cook's Notes:
Three pounds of uncooked corned beef will yield enough for this recipe. I sometimes like to simmer mine with 3 cans cheap beer plus enough water to cover for 3 hours. I like to quarter 3 pounds red potatoes and add them to the corned beef during the last half hour. I then remove the meat and potatoes and put the cabbage in the pot to simmer for 5 minutes. I then cut up the corned beef, potatoes, and refrigerate everything overnight, putting together the casserole the next day.
One sheet of puff pastry can replace the phyllo dough, no need for butter or spray. Excellent as leftovers.
Tip
Aluminum foil helps keep food moist, ensures it cooks evenly, keeps leftovers fresh, and makes clean-up easy.
