Ingredients
  

  • 1¼ pounds boneless skinless chicken breasts diced
  • 2 tablespoons olive oil divided
  • 2 tablespoons butter divided
  • Salt
  • Freshly ground black pepper
  • 3 teaspoons Italian seasoning divided
  • 1 teaspoon garlic powder divided
  • ½ teaspoon onion powder
  • 1 teaspoon lemon zest plus extra for garnish
  • 10 ounces zucchini sliced
  • 10 ounces yellow squash sliced
  • ⅓ cup finely shredded Parmesan cheese
  • 2 tablespoons chopped fresh parsley
  • 2 tablespoons fresh lemon juice

Instructions
 

  • Heat 1 tablespoon olive oil in a large skillet over medium-high heat.
  • Pat the chicken dry with paper towels.
  • Season the chicken with salt, pepper, 2 teaspoons Italian seasoning, ½ teaspoon garlic powder, onion powder, and lemon zest.
  • Melt 1 tablespoon butter into the skillet with the oil.
  • Add the chicken and cook for about 3 minutes per side until fully cooked and the internal temperature reaches 165°F (74°C).
  • Transfer the chicken to a plate and loosely cover with foil.
  • Add the remaining olive oil and butter to the skillet.
  • Stir in the zucchini and yellow squash.
  • Season the vegetables with salt, the remaining Italian seasoning, and garlic powder.
  • Cook for about 4 minutes until just tender.
  • Return the chicken to the skillet.
  • Drizzle with fresh lemon juice and gently toss everything together.
  • Sprinkle generously with Parmesan cheese and chopped parsley.
  • Serve the Skillet Lemon Parmesan Chicken warm with extra Parmesan and lemon zest if desired. It pairs beautifully with cooked orzo, rice, mashed potatoes, or cauliflower rice.

Notes

  • Serve over orzo, pasta, quinoa, rice, or cauliflower rice.
  • Fresh basil can replace parsley for a different herb flavor.
  • Romano cheese makes a delicious substitute for Parmesan.
  • Leftover chicken is excellent in wraps, salads, or pasta the next day.
