Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish and set it aside.
Peel the potatoes and carrots. Slice the potatoes into thin rounds and the carrots into thin coins. Place the vegetables into a large pot of salted water and boil for 8-10 minutes, or until just tender. Drain and set aside.
In a large skillet, melt 2 tablespoons of butter over medium heat. Add the shredded cabbage and diced onion, cooking until soft and lightly caramelized, about 8 minutes.
Crumble the corned beef into bite-sized pieces and set aside.
In a medium saucepan, melt the remaining 2 tablespoons of butter over medium heat. Whisk in the flour and cook for 1-2 minutes, stirring constantly to form a roux.
Gradually whisk in the milk, continuing to stir until the mixture thickens, about 4-5 minutes. Stir in 1 1/2 cups of shredded cheddar cheese, the salt, black pepper, and garlic powder. Mix until the cheese has melted and the sauce is smooth.
In the prepared casserole dish, layer half of the cooked potato slices, followed by half of the carrots, cabbage-onion mixture, and corned beef. Pour half of the cheese sauce over the layers. Repeat the layering process with the remaining ingredients and sauce.
In a small bowl, combine the breadcrumbs with the remaining 1/2 cup of shredded cheddar cheese. Sprinkle the mixture evenly over the casserole.
Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the casserole is bubbly.
Remove from the oven and let rest for 5 minutes before serving. Garnish with chopped parsley, if desired.
