One-Pan Italian Dressing Sausage and Potato Bake Step-by-step instructions

Before you start

Before you start, heat the oven to 400°F (200°C) and position a rack in the middle. Wash and quarter the red potatoes, leaving the skins on. Slice the smoked sausage into uniform coins.

Measure out the Italian dressing and grate the Parmesan cheese if using a block. Have your baking dish ready—a 9x13-inch or similar rectangular dish works well. No need to grease it; the dressing provides enough moisture and prevents sticking.

Instructions

Prep and Coat

1. 1Prepare the baking dish
   Heat the oven to 400°F (200°C). Place the quartered red potatoes and sliced smoked sausage in a large rectangular baking dish, spreading them into an even layer.
   Look for Potatoes and sausage should cover the bottom of the dish in a single layer.
   Tip Cut potatoes into similar-sized quarters so they cook evenly.
2. 2Add the dressing
   Pour the Italian dressing evenly over the potatoes and sausage. Use a spoon or your hands to toss everything until each piece is coated.
   Look for Every potato and sausage piece should look glossy with dressing.
   Tip If you prefer extra tang, add a splash of red wine vinegar.

The potatoes and sausage are evenly layered in the dish, each piece glistening with Italian dressing. The Parmesan is sprinkled over the top, creating a snowy blanket. The kitchen smells of herbs and garlic, and the oven is preheated and ready.

Bake to Golden

3. 3Top with Parmesan
   Sprinkle the grated Parmesan cheese over the dressed potatoes and sausage, covering the top evenly.
   Look for A light, even blanket of cheese covers the entire surface.
   Tip Freshly grated Parmesan melts better than pre-shredded.
4. 4Bake until golden
   Place the dish in the oven and bake for 40 to 45 minutes, until the potatoes are tender when pierced with a fork and the top is golden and bubbling.
   Look for The edges will be bubbly and the Parmesan will be golden brown.
   Tip For extra browning, broil for the last 2 minutes, watching closely.

After about 40 minutes, the top is golden and bubbling, with crispy edges pulling away from the sides. The aroma is rich and savory. A fork pierces the potatoes easily, and the cheese has melted into a delicious crust.

Rest and Serve

5. 5Serve hot
   Remove the dish from the oven and let it rest for 5 minutes. Scoop onto plates, making sure to get some of the crispy edges and cheesy topping.
   Look for The potatoes are fork-tender and the sausage is heated through.
   Tip A wide spatula helps lift the baked-on bits easily.

The dish has rested for 5 minutes, allowing the juices to settle. The cheese is set, and the potatoes are tender. Scooping out a portion reveals steamy, flavorful bites with crisp edges and a cheesy topping.

Common mistakes

One common mistake is overcrowding the baking dish, which traps steam and prevents browning. Use a large enough dish so the potatoes and sausage are in a single layer.

Another mistake is skipping the toss—make sure every piece is coated with dressing so nothing dries out.

Also, don't underbake: the potatoes need enough time to become tender, so check with a fork before pulling it out. If the top is browning too quickly, cover loosely with foil.

How to tell it’s done

The bake is done when the potatoes are fork-tender—a knife or fork should slide in with little resistance. The top should be golden brown with bubbling spots, and the edges of the dish will show caramelized bits of dressing and cheese.

The sausage will be heated through and slightly browned at the edges. If you like extra crispiness, you can broil for a couple of minutes at the end, but watch it closely to avoid burning.
