  • 0.5 tsp black pepper

  • 1 lemon (zest and juice)
Parmesan
  • 0.75 cup freshly grated Parmesan cheese
parsley
  • 2 tbsp chopped fresh parsley
basil
  • 1 tbsp chopped fresh basil
lemon slices for garnish
  • 1 lemon slices for garnish

Equipment

  • 1 cast iron skillet

Method
 

Season and cook the chicken
  1. Season the chicken pieces with Italian seasoning, paprika, onion powder, salt, and black pepper. Make sure every piece is coated for even flavor.
  2. Heat the olive oil in a large skillet over medium-high heat. Add a drop of water— it should sizzle right away.
  3. Cook the chicken for 5–6 minutes, stirring occasionally, until golden and cooked through. Transfer the chicken to a plate when no pink remains.
Cook zucchini and finish with lemon Parmesan
  1. Melt the butter in the same skillet. The pan should smell nutty and the butter should foam lightly.
  2. Add the zucchini and cook for 4–5 minutes, stirring once or twice, until tender-crisp. Look for bright green color with browned edges.
  3. Stir in the garlic and cook for 30 seconds. Keep it moving so it turns fragrant without browning.
  4. Return the chicken to the skillet. Spread everything into an even layer so it warms through quickly.
  5. Add the lemon zest and lemon juice. The skillet will loosen and smell fresh as the liquid bubbles.
  6. Sprinkle in the Parmesan cheese and stir until lightly melted. The sauce should look glossy rather than fully watery.
  7. Garnish with chopped parsley, chopped basil, and lemon slices before serving. Finish with a quick scatter right at the table.

Notes

For best browning, avoid crowding the skillet and use medium-high heat so the chicken reaches a golden crust in the first pass. Store leftovers in an airtight container in the refrigerator for up to 3 days; reheat gently in a skillet over medium heat until warmed through. Freezing is not recommended because zucchini can soften too much. If you want a dairy-light option, use part-skim Parmesan or a lactose-free Parmesan substitute and reduce the butter slightly to keep the sauce from getting oily.
