How to Make Skillet Lemon Parmesan Chicken with Zucchini and Squash Recipe
Step 1: Prepare and Season the Chicken
Start by cutting the chicken breasts into bite-sized pieces—this helps them cook quickly and soak up the seasoning. In a bowl, toss the chicken with salt, freshly ground black pepper, Italian seasoning, garlic powder, onion powder, and lemon zest. This simple seasoning mix is key to infusing the chicken with bright, savory notes that complement the fresh vegetables perfectly.
Step 2: Cook the Chicken in the Skillet
Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the seasoned chicken pieces in a single layer, giving them space to brown nicely. Cook them until they are golden on the outside and cooked through, about 6-8 minutes, stirring occasionally to ensure even cooking. Flavorful browning here creates a delicious base for the whole dish.
Step 3: Sauté the Zucchini and Squash
Using the same skillet, add the remaining olive oil and butter to melt together—this mixture creates a luxurious coating for the vegetables. Toss in the sliced zucchini and yellow squash along with a pinch more salt, pepper, Italian seasoning, and garlic powder. Cook, stirring frequently, until the vegetables are tender but still have a slight bite, about 5-7 minutes. The sizzling veggies will soak up those buttery, herbal flavors beautifully.
Step 4: Combine Chicken and Vegetables with Lemon and Parmesan
Return the cooked chicken back to the skillet and pour in the fresh lemon juice. Sprinkle the shredded Parmesan cheese evenly over everything, then add the chopped parsley. Gently toss the mixture together so the cheese melts slightly and the lemon juice brightens the entire dish. This final step melds all the components into one glorious, flavorful meal.
Step 5: Serve Hot with Extra Parmesan and Lemon Zest
Finish by sprinkling extra Parmesan and fresh lemon zest on top just before serving. These garnishes add a fresh and cheesy pop that makes every bite even more irresistible.

Make Ahead and Storage
Storing Leftovers

Freezing
You can freeze leftovers by placing the cooled chicken and vegetable mixture into a freezer-safe container. Frozen dishes are best enjoyed within 2 months. Thaw overnight in the fridge before reheating to keep the texture and flavor intact.
Reheating
To warm your leftovers, gently reheat in a skillet over medium heat with a splash of olive oil to revive the texture and avoid drying out. Alternatively, microwave in short bursts, stirring occasionally to distribute heat evenly. Either way, the dish will taste just as delightful as when freshly made.
FAQs
Can I use other types of squash for this recipe?
Absolutely! While zucchini and yellow squash provide a great balance in color and flavor, you can experiment with other varieties like pattypan or even mild summer squash. Just be sure to adjust cooking time since some squash types may be firmer or softer.
Is it possible to make this recipe gluten-free?
Yes, this Skillet Lemon Parmesan Chicken with Zucchini and Squash Recipe is naturally gluten-free as it doesn’t include any gluten-containing ingredients. Just double-check that your Italian seasoning and Parmesan are free from additives if you have severe gluten sensitivities.
Can I use fresh garlic instead of garlic powder?
Fresh garlic can certainly be used and will add a sharper, more pungent flavor. If using fresh, mince 1-2 cloves and sauté them with the vegetables to mellow the harshness and bring out that delightful aroma.
How can I make this recipe dairy-free?
To make it dairy-free, simply swap the butter with extra olive oil or a dairy-free margarine, and substitute the Parmesan cheese with a sprinkle of nutritional yeast or a dairy-free cheese alternative. The dish will still have great flavor with these tweaks.
Can I double the recipe for a larger crowd?
Yes, doubling or even tripling the ingredients works well. Just use a larger skillet or cook the chicken and vegetables in batches to ensure even cooking and proper browning. This recipe scales nicely without losing any of its charm.
