Preheat your oven to 400°F. Pat the chicken breast dry and season both sides lightly with salt, pepper, and orange zest.
In a shallow bowl, whisk the egg white. In another plate, spread the almond flour.
Dip the chicken first into the egg white, ensuring it is well-coated, then dredge it in the almond flour, pressing gently to adhere.
Heat the olive oil in a skillet over medium heat. Sear the chicken on each side until it forms a golden, crispy crust, about 2-3 minutes per side.
Meanwhile, in a small saucepan, combine the fresh orange juice, grated ginger, and minced garlic. Simmer the mixture over low heat for about 3-4 minutes until slightly thickened. Adjust seasoning with a pinch of salt and pepper if needed.
Once the chicken is seared, transfer it to the preheated oven and bake for an additional 8-10 minutes or until the chicken is fully cooked.
Plate the chicken and drizzle the warm orange sauce over the top. Optionally, garnish with additional orange zest or a few orange segments.
Serve immediately and enjoy your healthy, crispy zesty orange chicken.
