Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
In a shallow dish, combine the almond flour, turmeric, garlic powder, dried thyme, sea salt, and black pepper, mixing well to distribute the spices.
Pat the chicken breast dry with a paper towel and brush it with half of the olive oil to ensure the coating adheres.
Dredge the chicken in the almond flour mixture, pressing firmly to create an even, golden crust on both sides.
Place the crusted chicken on one side of the prepared baking sheet.
Trim the woody ends off the asparagus and toss the spears with the remaining olive oil on the other side of the baking sheet.
Bake for 18 to 22 minutes, or until the chicken reaches an internal temperature of 165°F and the asparagus is tender and slightly charred.
Remove from the oven and finish with a squeeze of fresh lemon juice over the chicken and vegetables before serving.
