Preheat the oven to 425°F. Line a baking sheet with parchment paper.
Pat the chicken breast dry and lightly coat it in almond flour. Set aside.
In a small bowl, whisk together orange juice, orange zest, soy sauce, minced garlic, grated ginger, cornstarch, and sesame oil to create the orange glaze.
Heat a non-stick skillet over medium-high heat and sear the coated chicken breast for 2 minutes on each side until golden, then transfer it to the prepared baking sheet.
Roast the chicken in the oven for 12-15 minutes or until it reaches an internal temperature of 165°F.
Meanwhile, toss broccoli florets in a drizzle of olive oil (optional), salt, and pepper, then roast them on a separate baking sheet in the oven for 10-12 minutes until tender.
Heat the cooked brown rice gently until warm if needed.
Once the chicken is done, drizzle the prepared orange glaze over the chicken. For a crisp finish, return the chicken to the oven for an additional 3-5 minutes.
Plate the crispy orange chicken with roasted broccoli and brown rice, and serve immediately.
