This little sheet pan of Italian roasted potatoes is the kind of recipe that feels like it’s always been around, even if it did come from the age of bottled salad dressing and busy weeknights. It reminds me of the church potlucks and harvest suppers I grew up with here in the Midwest, where red potatoes and a trusty bottle of Italian dressing could feed a crowd without much fuss. With just four ingredients, you drizzle, toss, and slide the pan into the oven. The dressing soaks into the red potatoes, the edges crisp up, and the herbs and garlic perfume the whole kitchen. It’s the sort of simple side dish you’ll find yourself making on repeat because it tastes like comfort but cooks like convenience.
Serve these Italian roasted red potatoes alongside baked chicken, meatloaf, or a simple pork roast for a hearty, stick-to-your-ribs supper. They’re lovely piled next to green beans, a tossed salad, or steamed broccoli to round out the plate. If you have leftovers, rewarm them in a skillet with a little butter and serve with eggs for breakfast, or fold them into a warm veggie bowl with roasted carrots and onions. A sprinkle of extra Parmesan at the table never hurts, and a little dish of ketchup on the side will keep the grandkids happy.
4-Ingredient Italian Roasted Red Potatoes
Servings: 4

Ingredients
2 pounds red potatoes, scrubbed and cut into 1-inch cubes
1/3 cup store-bought Italian dressing (any zesty or classic style)
2 tablespoons grated Parmesan cheese
1 teaspoon garlic powder
1/2 teaspoon kosher salt (or to taste, optional)
1/4 teaspoon black pepper (optional, to taste)
Nonstick cooking spray or 1 teaspoon vegetable oil for the pan
Directions
Preheat your oven to 400°F (200°C). Lightly spray a large sheet pan with nonstick cooking spray or rub it with a little vegetable oil so the potatoes don’t stick.
Scrub the red potatoes well and pat them dry. Cut them into roughly 1-inch cubes so they cook evenly. Scatter the cubed potatoes in a single layer on the prepared sheet pan.
Give the potatoes a light sprinkle of salt and pepper if using. This helps season them from the start, but keep in mind your Italian dressing and Parmesan will also add salt.
Drizzle the store-bought Italian dressing evenly over the cubed red potatoes right on the sheet pan. You want most of the potatoes to get a little shine from the dressing, but they don’t need to be swimming in it.
Sprinkle the grated Parmesan cheese and garlic powder evenly over the dressed potatoes. Use clean hands to gently toss everything together right on the pan, turning the potatoes so they’re lightly coated with the dressing, cheese, and garlic. Spread them back into a single layer, with as many cut sides down as possible for extra browning.
Place the sheet pan on the middle rack of the preheated oven. Bake for 25 to 30 minutes, stirring once about halfway through, until the potatoes are tender when pierced with a fork and the edges are golden and crisp.
Taste a potato and adjust seasoning at the end if needed, adding a pinch more salt or a light extra drizzle of Italian dressing if you like a brighter flavor. Serve the potatoes hot, right from the pan, or transfer to a warm serving dish.
Variations & Tips
You can nudge this simple recipe in many directions without losing its easy charm. For a little color, toss in a handful of thinly sliced red onion or bell pepper with the potatoes before roasting. If you like more crunch, roast the potatoes a bit longer, watching closely near the end so the cheese doesn’t burn. For a richer flavor, sprinkle an extra tablespoon of Parmesan over the potatoes during the last 5 minutes of baking. If you prefer a bit of heat, add a pinch of crushed red pepper flakes along with the garlic powder. You can also swap in a light Italian dressing if you’re watching fat and calories, just know they may brown a touch less. To keep this dish safe and wholesome, always scrub the potatoes well to remove dirt, trim off any green spots, and cut away any large sprouts. Use clean hands when tossing the potatoes on the sheet pan, and don’t leave the finished dish out at room temperature for more than 2 hours; refrigerate leftovers promptly in a shallow container. Reheat leftovers thoroughly in a 350°F oven or in a skillet until steaming hot. If your Italian dressing has been open a long time, check the date and give it a good shake and sniff before using; when in doubt, throw it out. And as with any hot sheet pan, use sturdy oven mitts and give the pan a moment to cool before you reach in to stir or serve.
