In a large skillet, heat olive oil over medium heat. Add the diced onion and bell pepper, sautéing until softened (about 5 minutes).
Add the minced garlic to the skillet and cook for another minute until fragrant.
In a large bowl, combine the sliced potatoes, smoked sausages, sautéed onion and bell pepper mixture, smoked paprika, oregano, salt, and pepper. Mix everything well to ensure the flavors are evenly distributed.
Transfer the mixture into a greased baking dish, spreading it evenly.
Pour the heavy cream over the potato and sausage mixture, allowing it to sink through the layers.
Sprinkle the shredded cheddar cheese on top of the mixture.
Cover the baking dish with aluminum foil and bake for 30 minutes. After 30 minutes, remove the foil and bake for an additional 15 minutes or until the potatoes are tender and the cheese is bubbly and golden brown.
Once cooked, let it cool for a few minutes before serving. Garnish with chopped parsley for a pop of color.
Notes
For a lighter option, use chicken or turkey sausage.
