Recipe Information
Ingredients
- 6 pieces sausage links (Italian or breakfast sausage)
- 4 medium-sized russet potatoes
- 2 medium-sized yellow onions
- 3 cloves garlic cloves
- 2 tablespoons olive oil
- 1 tablespoon butter
- 1 cup chicken broth
- 0.5 cup heavy cream
- 1 teaspoon dried thyme
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 1 cup shredded cheddar cheese
- 2 tablespoons parsley (optional, for garnish)
Instructions
Preheat your oven to 375°F (190°C).
Wash, peel, and thinly slice the potatoes into 1/4-inch rounds. Set them aside in a bowl of water to prevent browning.
Peel and thinly slice the onions. Mince the garlic cloves.
Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the sausage links and cook until browned on all sides, about 8-10 minutes. Remove the sausages from the skillet and slice them into 1/2-inch pieces.
Using the same skillet, add the remaining 1 tablespoon of olive oil and butter. Toss in the sliced onions and cook over medium heat until softened and caramelized, about 10 minutes. Stir frequently to prevent burning. Add the minced garlic and cook for another 1-2 minutes. Remove from heat.
Drain the potato slices and pat them dry with a clean kitchen towel.
Spray or grease a 9x13-inch casserole dish. Layer half of the potato slices on the bottom of the dish, followed by half of the cooked sausages and half of the caramelized onions. Repeat with the remaining potatoes, sausages, and onions.
In a mixing bowl, whisk together the chicken broth, heavy cream, dried thyme, salt, and black pepper.
Pour the liquid mixture evenly over the layered sausage, potatoes, and onions in the casserole dish.
Cover the dish tightly with aluminum foil and bake for 35 minutes.
Remove the foil, sprinkle the shredded cheddar cheese evenly over the top, and bake uncovered for an additional 15 minutes, or until the cheese is melted and bubbly and the potatoes are tender when pierced with a fork.
Remove from the oven and let rest for 5-10 minutes before serving.
Garnish with chopped parsley if desired, and serve warm.
