Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Scrub the russet potato and dice it into small, even cubes, then toss them in a bowl with half of the olive oil, sea salt, black pepper, and smoked paprika.
Spread the potatoes in a single layer on the prepared baking sheet and roast for 25 minutes, flipping halfway through, until they are golden and crispy.
While the potatoes are roasting, slice the chicken breast into thin strips and toss them with the remaining olive oil, garlic powder, and minced chipotle peppers.
Heat a large skillet over medium-high heat and add the seasoned chicken, cooking for about 3-4 minutes per side until the edges are beautifully charred and the meat is cooked through.
Remove the skillet from the heat, drizzle the lime juice over the chicken, and toss to combine the juices.
Plate the crispy potatoes alongside the spicy chipotle chicken and garnish with fresh cilantro for a bright finish.
