Preheat your oven to 400°F (200°C).
In a shallow dish, whisk together the egg white, lemon juice (squeezed from the lemon), garlic powder, dried thyme, salt, and pepper.
Place the almond flour in another shallow dish.
Dip the chicken breast in the egg white mixture, ensuring it’s well-coated, then dredge in almond flour to create a light, crispy coating.
Arrange the coated chicken on a baking tray lined with parchment paper.
In a separate bowl, toss the asparagus with olive oil, salt, and pepper.
Spread the asparagus on another baking sheet.
Bake the chicken for about 20-22 minutes, or until the chicken is cooked through and the coating is golden and crisp.
Simultaneously, roast the asparagus in the oven for 12-15 minutes until tender and slightly charred.
Plate the chicken alongside the roasted asparagus and garnish with a bit of lemon zest for an extra burst of flavor.
