Ingredients
- 1 ½ - 2 lbs red skin or other waxy potatoes unpeeled, sliced about ¼ inch thick
- 1 medium yellow onion sliced about ½ inch thick, thicker than the potatoes
- 3 tablespoons olive oil
- 2 teaspoons kosher salt
- Freshly cracked black pepper to taste
- 1 tablespoon fresh rosemary needles or about 1 teaspoon dried
Notes
- Line the baking pan with parchment paper for easier clean-up and no stuck-on potatoes or onions. Potatoes and onions will stick to aluminum foil.
- Don't skimp on the olive oil! It helps the potatoes and onions get nice and crisp.
- Use waxy potatoes like red skinned potatoes or Yukon Gold potatoes for best results.
- Slice the onions thicker than the potatoes so they don't burn. Onions have a lot of natural sugars, so they cook faster and can burn more easily.
- Use a mandoline slicer to slice the potatoes and onions. If you don't have a mandoline, don't stress about getting evenly thin slices. My mom and grandma always used a knife.
- Try to arrange the potatoes and onions in a single layer on a large baking sheet to maximum surface area for crispiness and even cooking.
- Don't open the oven. These potatoes need high heat to get nice and crisp. If you constantly open the oven to check on them, the temperature will drop and they'll take longer to cook.
- Try adding some other vegetables to the sheet pan along with the potatoes and onions for variation and added nutrition. I love adding jalapeños or red peppers, or other root vegetables such as parsnips, carrots, celery root, sweet potatoes, yams, turnips, radishes or rutabagas.
- I love the simplicity of the flavors in this recipe, but you can change up the vibe by adding different spices and herbs.
