Creating Cheesy Ranch Potatoes and Smoked Sausage is straightforward if you follow these steps:

1. Preheat Oven: Begin by preheating your oven to 400°F (200°C).
2. Prepare the Potatoes: In a large mixing bowl, combine the halved baby potatoes with olive oil, garlic powder, onion powder, salt, and pepper. Toss to coat evenly.
3. Combine Sausage: Add the sliced smoked sausage to the bowl and mix thoroughly with the potatoes.
4. Add Ranch Seasoning: Sprinkle the ranch dressing mix over the potato and sausage mixture. Stir until everything is well coated.
5. Transfer to Baking Dish: Pour the mixture into a large baking dish in an even layer.
6. Bake: Place the dish in the preheated oven and bake for 30-35 minutes, or until the potatoes are fork-tender.
7. Add Cheese: Pull the dish out of the oven and sprinkle the shredded cheddar cheese evenly over the top. Return to the oven for an additional 5-10 minutes, or until the cheese is melted and bubbly.
8. Mix in Sour Cream: Once the cheese is fully melted, remove the dish from the oven and mix in the sour cream until well combined.
9. Garnish: Sprinkle with chopped green onions if desired for a fresh touch.
10. Serve: Let it cool for a few minutes before serving to allow the flavors to settle.

These simple steps will lead you to a delightful dish filled with cheesy goodness and savory sausage that’s sure to become a family favorite.
