Ingredients
Scale
Vegetables
- 1½ – 2 lbs red skin potatoes (or other waxy potatoes, unpeeled, sliced about 1/4 inch thick)
- 1 medium yellow onion (sliced about 1/2 inch thick, thicker than the potatoes)
Seasoning & Oil
- 3 tablespoons olive oil
- 2 teaspoons kosher salt
- Freshly cracked black pepper to taste
- 1 tablespoon fresh rosemary needles or about 1 teaspoon dried rosemary
Instructions
- Preheat Oven and Prepare Pan: Preheat the oven to 425℉ (220℃) and line a sheet pan with parchment paper to prevent sticking and ensure easy cleanup.
- Toss Potatoes and Onions with Seasonings: In a large bowl, add the sliced potatoes and onions. Drizzle with olive oil, then sprinkle with kosher salt, freshly cracked black pepper, and rosemary. Toss everything together thoroughly until all pieces are evenly coated with the oil and seasonings.
- Arrange on Sheet Pan: Spread the seasoned potatoes and onions out on the prepared sheet pan in a single layer to ensure even roasting and crisping.
- First Half of Roasting: Place the sheet pan in the preheated oven and bake for 20 minutes. This initial roasting step starts softening the potatoes and onions and developing flavor.
- Toss and Flip: After 20 minutes, remove the pan and use a spatula to toss and flip the potatoes and onions. This redistribution doesn’t have to be perfect, but helps achieve even browning and crispness.
- Final Roasting: Return the pan to the oven and bake for an additional 15-20 minutes, or until the potatoes are golden brown and crisp in spots, and the onions are tender and caramelized.
- Serve Immediately: Remove from the oven and serve the crispy roasted potatoes and onions immediately to enjoy them at their best texture and flavor.
Notes
- This easy side dish requires just 5 simple ingredients and is versatile enough to pair with a wide range of main courses.
- Using waxy potatoes with the skin on and slicing thinly helps achieve a crispy exterior and creamy interior.
- Fresh rosemary provides the best flavor, but dried rosemary works well too.
- Ensure the potatoes and onions are spread in a single layer to allow even roasting and perfect crispness.
