Toss the potatoes with the minced garlic, dijon mustard, kosher salt, pepper and olive oil. Spread in a single layer across two baking sheets. Roast in the oven for 30-40 minutes, tossing occasionally, until parts are golden brown. Squeeze juice from the lemon halves over the potatoes and stir to coat. Continue to bake for 3-4 minutes. Remove the potatoes from the oven, toss with the parsley, and season with additional kosher salt and lemon juice if desired.
