Preheat the oven to 425°F and line a baking sheet with parchment paper.
In a shallow dish, combine the buttermilk with garlic powder, paprika, black pepper, and a pinch of salt.
Place the chicken breast in the buttermilk mixture ensuring it is fully submerged. Allow it to marinate for at least 30 minutes.
In another dish, mix the almond flour with a little extra paprika, garlic powder, salt, and pepper for additional flavor.
Remove the chicken from the marinade and gently dredge it in the almond flour mixture, coating all sides evenly.
Arrange the coated chicken on one side of the baking sheet.
Cut the sweet potato into wedges and toss them in olive oil with a sprinkle of salt and pepper.
Place the sweet potato wedges on the baking sheet alongside the chicken.
Bake in the oven for 25 to 30 minutes, flipping the wedges halfway through, until the chicken is cooked through and the sweet potato wedges are tender and slightly crispy.
Serve warm and enjoy your balanced, crispy yet light meal.
