1. Preheat the oven to 375°F (190°C). Butter a 9x9-inch (23x23 cm) baking dish. 2. In a large skillet over medium heat, melt the butter with the oil. Add the chopped onion and sauté until translucent, about 5 minutes. Add the garlic and cook 30 seconds until fragrant. 3. Add the chopped canned corned beef to the skillet and brown lightly, breaking it into pieces, about 4–5 minutes. 4. Stir in the flour and cook 1 minute to remove raw taste. Gradually whisk in the stock and milk until a smooth gravy forms. Add Worcestershire sauce, salt, and pepper. Simmer 3–4 minutes until slightly thickened. 5. Layer half of the sliced potatoes in the bottom of the prepared dish. Top with half the carrots, half the rutabaga, and half the corned beef and gravy mixture. Repeat the layers with remaining potatoes, carrots, rutabaga, and gravy. 6. Sprinkle shredded cheddar over the casserole, then evenly distribute the breadcrumbs on top. 7. Cover with foil and bake 30 minutes. Remove foil and bake an additional 15–20 minutes until the top is golden and vegetables are tender when pierced with a knife. 8. Let rest 5 minutes, garnish with chopped parsley, and serve hot.
