The recipe
(8 servings)Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Preheat the oven to 375°F (190°C). Place the quartered potatoes in a pot, cover with water, and boil for about 15 minutes until tender. Drain well and mash.
Heat the olive oil in a large skillet over medium heat. Add the diced onion and cook about 5 minutes until soft, then add the garlic and cook 1 minute more.
Add the Italian sausage to the skillet and break it up. Cook about 8 minutes until browned and it reaches 160°F (71°C) in the thickest part. Drain excess fat.
Pour in the broth and add the kale. Stir, cover, and cook 3 to 4 minutes until the kale wilts. Season with salt and pepper.
Stir the milk and beaten egg into the mashed potatoes. Season with salt and pepper to taste.
Spread the sausage and kale mixture evenly into the prepared pie crust in a pie plate. Spoon the potato mixture over the top and spread it smooth.
Sprinkle the shredded Swiss cheese over the potatoes. Bake about 25 to 30 minutes until the crust is golden, the top is lightly browned, and the egg is set at 160°F (71°C).
Let the pie rest for 10 minutes before slicing and serving.
