Kosher salt and freshly ground black pepper, to taste
Instructions
Preheat oven to 425 degrees F. Lightly oil a baking sheet or coat with nonstick spray.
In a large pot of boiling water, cook potatoes until tender, about 15-20 minutes; drain well.
In a small bowl, whisk together olive oil, Dijon mustard, whole grain mustard, garlic, honey, thyme and rosemary; season with salt and pepper, to taste.
Place potatoes onto the prepared baking sheet. Using a potato masher or fork, carefully smash the potatoes until flattened but still in one piece. Brush each potato with mustard mixture.
Place into oven and bake for 18-20 minutes, or until golden brown and crisp.
