Preheat your oven to 375°F (190°C).
Peel the potatoes and carrots. Slice the potatoes into 1/4-inch thick rounds and cut the carrots into thin coin shapes. Core the cabbage and cut it into large chunks.
Bring a large pot of salted water to a boil. Add the potatoes and carrots, and cook for 5 minutes. Add the cabbage and cook for an additional 3 minutes. Drain the vegetables and set them aside.
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes to form a roux.
Slowly whisk in the milk, ensuring there are no lumps. Cook, stirring constantly, until the mixture thickens, about 5 minutes.
Remove the saucepan from heat and stir in 1 1/2 cups of the shredded cheddar cheese until melted. Season with salt, pepper, and garlic powder. Set the cheese sauce aside.
Grease a 9x13-inch casserole dish. Layer half of the cooked potatoes, carrots, cabbage, and corned beef in the dish. Pour over half of the cheese sauce. Repeat with the remaining vegetables, corned beef, and cheese sauce.
In a small bowl, mix the panko breadcrumbs with olive oil and the remaining 1/2 cup of shredded cheddar cheese. Sprinkle the breadcrumb mixture evenly over the top of the casserole.
Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and bubbling.
Remove from the oven and let the dish rest for 5 minutes. Sprinkle with chopped fresh parsley before serving.
