Our version of Shepherd's Pie, inspired by all the best classic Irish comfort foods
Preheat oven to 400 degrees. In a large skillet, heat olive oil over medium-high heat. Add garlic and sweet onion, cook until aromatic, about 1-2 minutes. Add corned beef and cornstarch, mixing together with a meat chopper until the texture of ground beef. Turn heat to medium, add half-and-half and 1/2 teaspoon pepper to the pan. Cook just until mixture begins to thicken. Remove from heat and pour into a 9x9" pan or Good Cook 3-Quart Square Ceramic Baking Dish. Mix together mashed potatoes and parsley. Salt to taste. Spoon on top of corned beef mixture. Top with several pats of butter. Bake for 20-30 minutes, or until the mashed potatoes begin to brown lightly. Serve and enjoy!
