Ingredients

Why this recipe works

The method here is simple but effective. Tossing the potatoes and sausage with Italian dressing before baking ensures every piece is coated in flavor. The dressing's oil helps the potatoes roast and crisp up, while the vinegar and herbs add brightness. Baking everything together in a single layer allows the heat to circulate evenly, cooking the potatoes through and browning the sausage and cheese on top.

The Parmesan cheese creates a golden, bubbly crust as it melts and bakes. This crust adds texture and a rich, savory flavor that complements the tangy dressing. The high oven temperature helps the edges of the potatoes become crispy while the centers stay tender. The result is a dish with contrasting textures—crispy edges, soft interiors, and a cheesy top that pulls apart in satisfying strands.

Notes and substitutions

Smoked sausage is the star here because it's already cooked, so it just needs to heat through and brown. Look for a good-quality smoked sausage or kielbasa, and slice it into coins about 1/4-inch thick.

The red potatoes hold their shape well during baking and have a nice waxy texture. Quarter them so they cook quickly and evenly. If you can't find small red potatoes, Yukon Golds are a great substitute.

Italian dressing is key—use a good-quality bottled one or make your own with olive oil, red wine vinegar, garlic, and Italian herbs. The dressing should be well-emulsified so it coats the ingredients evenly.

Grated Parmesan, not shredded, melts more smoothly and creates a better crust. Freshly grated from a block is best, but pre-grated works in a pinch. This recipe is easily customizable: add bell peppers, onions, or cherry tomatoes if desired.

• Italian dressing: Use a homemade vinaigrette of olive oil, red wine vinegar, garlic, and Italian herbs.
• Smoked sausage: Substitute with kielbasa, andouille, or any fully cooked smoked sausage.
• Red potatoes: Yukon Gold or baby potatoes work well; no need to peel.
• Parmesan: Pecorino Romano adds a sharper, saltier flavor.
