Making Cheesy Ranch Potatoes and Smoked Sausage is a breeze when you follow these simple steps:

1. Preheat the Oven: Start by preheating your oven to 400°F (200°C).
2. Prepare the Baking Dish: Grease a large baking dish (9×13 inches works well) with cooking spray or olive oil.
3. Combine the Potatoes and Sausage: In a large bowl, mix the halved baby potatoes and sliced smoked sausage.
4. Season the Mixture: Drizzle olive oil over the potato and sausage mixture. Add garlic powder, onion powder, salt, pepper, and half of the ranch seasoning. Toss well until everything is evenly coated.
5. Transfer to Baking Dish: Pour the potato and sausage mixture into the greased baking dish and spread it out evenly.
6. Cover with Foil: Cover the baking dish loosely with aluminum foil to trap steam while cooking.
7. Bake: Place in the preheated oven and bake for 30 minutes.
8. Add Cheese and Sour Cream: After 30 minutes, remove the foil. In a small bowl, mix the sour cream with the remaining ranch seasoning. Spread the mixture evenly over the potatoes and sausage. Sprinkle shredded cheddar cheese on top.
9. Bake Again: Return to the oven (uncovered) and bake for an additional 15 minutes, or until the cheese is bubbly and golden.
10. Cool and Garnish: Remove from the oven and let it cool slightly. Garnish with chopped green onions or parsley, if desired.

These steps will help you create a delightful and satisfying meal that everyone will adore.
