Preparing Cheesy Ranch Potatoes and Smoked Sausage is simple when you follow these straightforward steps:

1. Preheat Oven: Begin by preheating your oven to 400°F (200°C).
2. Prepare Potatoes: In a large bowl, combine the diced potatoes with olive oil, salt, and pepper. Stir well to coat all the potatoes evenly.
3. Add Sausage: Add the sliced smoked sausage to the potato mixture, ensuring it is evenly distributed.
4. Mix Ranch seasoning: Sprinkle the ranch seasoning packet over the potato and sausage mixture. Toss well until everything is well-coated with seasoning.
5. Transfer to Baking Dish: Pour the mixture into a greased baking dish, spreading it out evenly.
6. Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the potatoes are tender and golden brown.
7. Add Cheese: Remove the dish from the oven and sprinkle the shredded cheddar cheese on top.
8. Final Bake: Return the dish to the oven and bake for an additional 5-10 minutes, or until the cheese is melted and bubbly.
9. Mix in Sour Cream: Remove the dish from the oven, let it cool slightly, and then stir in the sour cream until well combined.
10. Serve Hot: Serve the cheesy ranch potatoes and smoked sausage warm, garnished with additional cheese if desired.
