How to Make Creamy Mustard Roasted Potatoes

1. Preheat your oven to 425°F. Line a baking sheet with parchment paper or lightly grease it to prevent sticking.
2. In a large bowl, toss the halved or quartered baby Yukon Gold potatoes with olive oil, kosher salt, black pepper, and garlic powder until evenly coated.
3. Spread the potatoes out in a single layer on the prepared baking sheet. Roast in the preheated oven for about 30-35 minutes, flipping halfway through, until golden brown and crisp on the edges and tender inside.
4. While the potatoes roast, prepare the creamy mustard sauce by whisking together sour cream, Dijon mustard, mayonnaise, fresh lemon juice, chopped parsley, and smoked paprika in a small bowl until smooth.
5. Once the potatoes are done roasting, transfer them to a large bowl and immediately toss them with the creamy mustard sauce so the warm potatoes soak up the flavors.
6. Serve warm, garnished with additional chopped parsley for a fresh pop of color and flavor.

Tips for the Best Results

• Choose Yukon Gold potatoes for the perfect balance of creaminess and crispiness.
• Don’t overcrowd the baking sheet; give potatoes space to roast evenly and get crispy.
• Adjust the amount of mustard in the sauce to your taste for more or less tang.
• For extra flavor, add a pinch of smoked paprika or fresh herbs like thyme or rosemary.
• Let the potatoes rest for a few minutes after roasting to allow the sauce to set slightly.

Storage and Reheating

Store leftover creamy mustard roasted potatoes in an airtight container in the refrigerator for up to 3 days. This makes a great make-ahead side for busy weeknights or meal prep.

To reheat, spread the potatoes on a baking sheet and warm them in a 375°F oven for about 10-15 minutes until heated through and crispy again. Avoid microwaving to maintain the best texture.
