Ingredients
4 large baking potatoes1 tablespoon butter1 medium onion, sliced1-1/2 cups finely chopped cooked corned beef1/2 teaspoon salt1/4 teaspoon pepper 1 teaspoon prepared mustard, optional 1 cup shredded Swiss cheese1/3 cup Thousand Island salad dressing1/2 cup thinly sliced green onions or minced fresh parsley
Preparation
Preheat oven to 400°. Scrub potatoes; pierce several times with a fork. Bake until tender, 50-75 minutes. Meanwhile, in a large skillet, heat butter over medium heat. Add onion; cook and stir until softened, 10-15 minutes. Reduce heat to medium-low; cook until deep golden brown, 20-30 minutes, stirring occasionally.
Stir in corned beef, salt, pepper and mustard, if desired; heat through. With a sharp knife, cut an “X” in each potato. Fluff pulp with a fork; season with salt and pepper. Spoon corned beef mixture over top. Top with cheese, dressing, and green onions.
