Preheat your oven to 400°F (200°C).
Trim the woody ends off the asparagus and place the spears on a parchment-lined baking sheet.
Drizzle the asparagus with 0.5 tbsp of olive oil and season with half of the sea salt and black pepper.
Roast the asparagus in the oven for 12-15 minutes until tender and slightly charred.
While the asparagus roasts, season the chicken breast on both sides with the dried thyme, dried rosemary, and the remaining salt and pepper.
Heat the remaining 0.5 tbsp of olive oil in a large skillet over medium-high heat.
Place the chicken in the skillet and sear for 6-7 minutes per side, or until the internal temperature reaches 165°F.
In the final minute of cooking, add the minced garlic to the pan and sauté until fragrant.
Pour the lemon juice and lemon zest over the chicken, swirling the pan to create a light glaze.
Remove from heat and let the chicken rest for 3 minutes.
Serve the chicken alongside the roasted asparagus and garnish with the sliced almonds for added fiber and texture.
