Prepare the Chicken: Start by patting the chicken breasts dry with paper towels. Season both sides with salt, pepper, garlic powder, onion powder, oregano, and thyme. Zest the lemon directly onto the seasoned chicken for added flavor.
Heat the Skillet: In a large skillet, heat the olive oil over medium-high heat. Once hot, add the seasoned chicken breasts, cooking for about 5-6 minutes on each side until they are golden brown and cooked through (internal temperature should reach 165°F or 75°C). Remove the chicken from the skillet and set aside.
Sauté the Asparagus: In the same skillet, add the trimmed asparagus. Sauté for about 2-3 minutes until they turn vibrant green and are tender yet crisp, stirring occasionally.
Deglaze the Skillet: Pour the chicken broth into the skillet, scraping up any brown bits from the bottom to incorporate the flavors. Allow the broth to simmer for 1-2 minutes.
Add Lemon Juice: Squeeze the juice of the lemon into the skillet, stirring to combine. Let it bubble for an additional minute to create a light sauce.
Combine Chicken and Asparagus: Return the cooked chicken breasts back into the skillet with the asparagus and allow everything to heat through for another 2-3 minutes. Baste the chicken and asparagus with the lemony broth.
Garnish and Serve: Remove from heat, sprinkle with fresh parsley, and serve immediately.
