Recipe Information
Ingredients
- 1.5 pounds baby potatoes
- 1 large yellow onion
- 3 tablespoons olive oil
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 0.5 teaspoon garlic powder
- 0.5 cup mayonnaise
- 0.25 cup sour cream
- 1 tablespoon Dijon mustard
- 1 teaspoon apple cider vinegar
- 2 tablespoons fresh parsley
- 2 tablespoons fresh chives
Instructions
Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper.
Wash and halve the baby potatoes. Peel the onion and cut it into thick slices.
In a large bowl, toss the potatoes and onion slices with olive oil, salt, black pepper, and garlic powder. Make sure everything is evenly coated.
Spread the potatoes and onions in a single layer on the prepared baking sheet.
Roast in the preheated oven for 30-35 minutes, or until the potatoes are golden brown and crispy, and the onions are caramelized. Stir once halfway through cooking.
While the vegetables are roasting, prepare the dressing. In a medium bowl, whisk together the mayonnaise, sour cream, Dijon mustard, apple cider vinegar, and a pinch of salt and pepper. Set aside.
Finely chop the parsley and chives and add them to the dressing. Stir to combine.
Once the potatoes and onions are done roasting, let them cool for 5 minutes, then transfer them to a large mixing bowl.
Pour the creamy dressing over the warm vegetables and gently toss to coat everything evenly.
Serve the roasted creamy potato and onion salad warm, or chill for 30 minutes in the refrigerator if you prefer it cold.
