Preheat your oven to 425°F.
In a shallow dish, combine almond flour, garlic powder, salt, pepper, chopped rosemary, and thyme.
Pat the chicken breast dry and squeeze the juice of half a lemon over it.
Coat the chicken breast evenly in the almond flour mixture.
Heat a non-stick skillet over medium-high heat; lightly sear the chicken for 2-3 minutes on each side until it becomes golden and crispy.
While the chicken sears, toss the asparagus with olive oil, salt, and pepper on a baking sheet.
Roast the asparagus in the preheated oven for 10-12 minutes, until tender and slightly crisp.
Finally, transfer the seared chicken to the oven (if needed) for an additional 5-7 minutes to ensure it is cooked through.
Remove the chicken and asparagus from the oven, squeeze a little extra lemon juice over them, and serve immediately.
