How to Make Creamy Mustard Roasted Potatoes
- Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper for easy cleanup.
- In a large bowl, toss the halved baby potatoes with olive oil, kosher salt, black pepper, garlic powder, and smoked paprika if using. Make sure each potato is evenly coated.
- Spread the potatoes cut side down on the prepared baking sheet in a single layer. Roast for 30-35 minutes, flipping halfway through, until golden and crispy on the outside and tender inside.
- While the potatoes roast, prepare the creamy mustard sauce by whisking together Dijon mustard, sour cream, mayonnaise, lemon juice, and chopped parsley in a small bowl. Adjust salt and pepper to taste.
- Once the potatoes are done, transfer them to a large serving bowl and gently fold in the creamy mustard sauce until all potatoes are evenly coated.
- Garnish with extra fresh parsley and a light sprinkle of black pepper before serving. Serve immediately while warm and creamy.
Tips for the Best Results
- Use baby Yukon gold potatoes for the best texture and flavor.
- Make sure the potatoes are dry before tossing in oil to get them crispy.
- Don’t overcrowd the baking sheet to ensure even roasting.
- Flip the potatoes halfway through roasting for golden brown edges on both sides.
- Adjust the mustard level in the sauce to suit your taste—add a little honey for sweetness if desired.
Storage and Reheating
Store leftover creamy mustard roasted potatoes in an airtight container in the refrigerator for up to 3 days. The sauce will thicken as it chills, so gently stir before reheating.
To reheat, warm the potatoes in a skillet over medium heat or in a 350°F oven until heated through. Avoid microwaving to keep the potatoes crispy and prevent the sauce from separating.
