A delightful casserole combining creamy potatoes, tender kale, and savory sausage, topped with melted cheese.
Preheat your oven to 450°F and position a rack in the middle.
Preheating ensures even cooking and a perfect texture.
Peel and chop the potatoes into chunks. Boil them in a Dutch oven with enough water to cover for about 15 minutes until tender.
Cut potatoes evenly to ensure they cook at the same rate.
Drain the potatoes and mash them in a bowl with butter, 1/4 cup of broth, vinegar, and a pinch of salt and pepper.
Use a potato masher or fork for a rustic texture.
Chop the kale leaves and boil them in the reserved potato water for 10 minutes until tender. Drain and squeeze out excess water.
Refreshing kale under cold water helps retain its vibrant color.
Mix the kale and half of the cheese into the mashed potatoes. Spread this mixture into a buttered casserole dish.
Butter the dish to prevent sticking and enhance flavor.
In a skillet, brown the sausage slices over medium heat. Remove and set aside.
Browning adds a caramelized flavor to the sausage.
In the same skillet, sauté the onions until golden. Combine with the sausage.
Stir frequently to prevent burning and ensure even cooking.
Scatter the sausage and onion mixture over the potato layer. Top with the remaining cheese and pour the rest of the broth over.
Layering ensures an even distribution of flavors.
Bake the casserole for 20 minutes until heated through and the cheese is melted and bubbly.
Let the casserole rest for a few minutes before serving to set the layers.
Serve the casserole warm and enjoy your hearty meal.
Garnish with fresh herbs like parsley for a pop of color.
