Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper to prevent sticking.
Wash and dice the russet potato into small 1/2-inch cubes to ensure they cook quickly and evenly.
In a bowl, toss the potato cubes with the olive oil, half of the garlic powder, half of the paprika, and a pinch of salt and pepper.
Spread the potatoes on one side of the baking sheet and roast for 15 minutes.
While the potatoes are roasting, cut the chicken breast into bite-sized nugget pieces.
In a shallow bowl, whisk together the almond flour with the remaining garlic powder, smoked paprika, sea salt, and black pepper.
Press each piece of chicken firmly into the almond flour mixture until all sides are thoroughly coated.
Remove the baking sheet from the oven, flip the potatoes, and place the chicken nuggets on the empty side of the tray.
Return the tray to the oven and bake for an additional 15 to 18 minutes until the chicken is cooked through and the potatoes are golden brown.
