Crispy on the outside, soft and tender on the inside, these Mustard-Roasted Potatoes are a must at your next dinner party.

Whenever I have guests over for dinner on the weekend, I try to include dishes that are a bit unusual. Last weekend, for example, I served a cold terrine as the starter. Made with layers of vegetables and cream cheese, it took me a good two hours to prepare, but the results were nothing short of spectacular. And this weekend I’m finally trying my hand at agnolotti del plin, tiny pasta parcels similar to ravioli, which are a regional specialty in the Piedmont region of Italy. Making these complex dishes serves as a challenge to me and a surprise for my guests. Other times, I simply take the familiar and give it a delicious makeover. That’s what I did with these roasted potatoes. By combining them with whole-grain mustard, the humble tubers have raised their game and become—dare I say—elegant.
Admittedly, roasted potatoes need little embellishing to be delicious, but the great thing is that they can take on a wide variety of flavor profiles, whether that be a simple seasoning of olive, garlic, salt, and pepper, or a more complex romesco sauce made with tomatoes, sweet peppers, almonds, garlic, olive oil, and vinegar. This delectable recipe though, has the distinct taste of mild whole-grain mustard, which, along with the lemon, garlic, and herbs, turns these taters into something majestic.

Are Mustard-Roasted Potatoes Healthy?
Potatoes are low in fat and a source of fiber, vitamins, and minerals. While butter does add saturated fat, it also delivers rich flavors and should not be omitted. That said, it can be replaced with a plant-based butter if you’re looking to make this dish vegan-friendly. If you’re watching your sodium intake, feel free to skip the salt. The rest of the ingredients provide enough flavor.
Why Whole-Grain Mustard?
Whole-grain mustard actually has a lot going for it. First, there’s the texture. Those tiny mustard seed grains are present in every bite, providing a delightful crunch. It also has a milder, less astringent flavor than other mustards, which can sometimes be quite sharp or even hot. The mustard also has a more rustic look, making it especially appealing in recipes where it takes center stage, such as these roasted potatoes.
I love using whole-grain mustard in potato salads, dips, dressings with lemon and honey, and in creamy sauces for chicken and pork chops. And did you know you could make a delightful soup using whole-grain mustard? Simply sauté diced potatoes with leeks and garlic, add chicken stock, and a few heaping tablespoons of grainy mustard. Cook for 15 minutes, add cream, purée until smooth and serve with a scattering of crispy, crumbled bacon!

How To Make Ahead And Store
Let the potatoes cool completely, then put them in an airtight container in the fridge where they should keep for up to 4 days. To reheat, place them in an oven set at 350°F for 10 minutes. As for freezing the potatoes, you can do so, though the texture of the potatoes may suffer.
