Preheat your oven to 400°F (200°C).

Wash the baby potatoes and cut them in half or quarters.

Slice the smoked sausage into ¼-inch thick rounds.

In a small bowl, mix together the ranch seasoning, garlic powder, onion powder, and black pepper.

Place the halved potatoes in a large bowl. Drizzle with olive oil and sprinkle with half of the ranch seasoning mixture. Toss the potatoes until they’re evenly coated.

Line a baking sheet with parchment paper or lightly grease it.

Evenly spread the seasoned potatoes on the baking sheet in a single layer.

Scatter the sliced smoked sausage pieces over the potatoes.

Place the baking sheet in the preheated oven and roast for 35-40 minutes, or until the potatoes are golden brown and tender.

Remove the baking sheet from the oven and sprinkle the shredded cheddar cheese over the potatoes and sausage. Bake for an additional 5 minutes, or until the cheese is melted.

Garnish with freshly chopped parsley and serve hot with a dollop of sour cream, if desired.
