Italian Dressing Sheet Pan Potatoes

If you are looking for an effortless, flavor-packed side dish, these Italian dressing sheet pan potatoes are an absolute winner. Using a bottle or homemade blend of zesty Italian dressing infuses the potatoes with garlic, herbs, and oil all at once, yielding crispy edges and tender, fluffy centers with virtually zero fuss.

Ingredients

Potatoes: 2.5 lbs (Russet potatoes for maximum crispiness, or Yukon Golds for a buttery interior; washed and cut into 1-inch cubes)
Italian dressing: 1/2 cup (your favorite store-bought brand or a homemade vinaigrette)
Parmesan cheese: 1/3 cup, freshly grated (adds a fantastic savory crust)
Garlic powder: 1/2 teaspoon (optional, for extra punch)
Salt and black pepper: To taste
Fresh parsley or chives: 2 tablespoons, chopped (for garnish)

Step-by-Step Instructions

Step 1: Prep and Preheat

Preheat your oven to 400°F (200°C). High heat is crucial for getting a great golden crust on the potatoes.
Line a large sheet pan with parchment paper or heavy-duty aluminum foil lightly coated with cooking spray for easy cleanup.

Step 2: Season the Potatoes

Dry the potatoes: Pat your cubed potatoes completely dry with paper towels. (Removing excess surface moisture helps them crisp up instead of steam).
Coat: Place the potatoes directly onto the sheet pan. Drizzle the Italian dressing evenly over them, then sprinkle with garlic powder, salt, and pepper.
Toss: Use your hands or a spatula to toss everything together right on the pan until every potato cube is evenly coated. Spread them out into a single layer with a little space between each piece.

Step 3: Roast

First bake: Place the sheet pan in the oven and roast for 25 minutes.
Flip: Remove the pan, give the potatoes a good stir or flip with a spatula, and spread them back out.

Step 4: Add the Cheese & Finish

Parmesan crust: Sprinkle the freshly grated Parmesan cheese evenly over the top of the hot potatoes.
Final roast: Return to the oven for another 10 to 15 minutes, or until the potatoes are fork-tender on the inside, deeply golden brown, and the cheese has melted into a crispy crust.

Step 5: Serve

Remove from the oven, garnish with fresh chopped parsley or chives, and serve hot!

Chef’s Tip: For extra protein, you can toss sliced bell peppers, onions, or chunks of smoked sausage onto the same sheet pan during the last 15 minutes of baking to turn this side dish into a complete one-pan meal.
