1. Preheat your oven to 400°F (200°C). Grease a large baking dish with olive oil.
2. In a large bowl, combine the diced potatoes, olive oil, and ranch seasoning mix. Toss until the potatoes are evenly coated.
3. Spread the potatoes in the prepared baking dish and bake for 30 minutes, stirring halfway through, until they are tender and golden brown.
4. While the potatoes are baking, heat a skillet over medium heat. Add the sliced smoked sausage and cook until browned, about 5 minutes.
5. In a small bowl, mix together the sour cream and milk until smooth.
6. Once the potatoes are done, remove them from the oven. Stir in the cooked sausage, sour cream mixture, and half of the shredded cheddar cheese.
7. Sprinkle the remaining cheese on top and return the dish to the oven. Bake for an additional 10 minutes, or until the cheese is melted and bubbly.
8. Garnish with chopped green onions if desired and serve warm.
