Begin by washing the potatoes thoroughly under running water. Cut them into bite-sized pieces, ensuring similar sizes for even cooking. Set aside while you get your skillet ready.

In a large, heavy-bottom skillet, heat over medium heat, and add the smoked sausage. Sauté for about 5-7 minutes, stirring occasionally until browned and fragrant.

Once your sausage is browned, add the prepared potato pieces along with the ranch seasoning mix. Stir together until the potatoes are evenly coated, about 2 minutes.

Drizzle olive oil over the sausage and potato mixture. Gently toss everything while seasoning with salt and pepper to taste. This should take another minute.

Cover the skillet and let it cook for approximately 25 minutes over medium heat, stirring occasionally. The potatoes should be tender and golden brown.

Once the potatoes are tender, sprinkle shredded cheddar cheese over the top, then cover the skillet. Allow the cheese to melt for about 5 minutes.

Serve hot straight from the skillet, optionally garnished with fresh herbs.
