How to Make Skillet Lemon Parmesan Chicken with Zucchini and Squash Recipe
Step 1: Cook the Chicken to Golden Perfection
Start by heating 1 tablespoon of olive oil in your skillet over medium heat. While the oil warms, season the diced chicken breasts generously with salt, pepper, half of the Italian seasoning, half of the garlic powder, onion powder, and the lemon zest. This seasoning combo promises every bite will be bursting with flavor. Add the chicken to the hot skillet and cook, stirring occasionally, until each piece is nicely browned and cooked through. This step is crucial because a perfectly seared chicken forms the delicious base for the entire dish.
Step 2: Sauté the Zucchini and Squash Until Tender
Once the chicken is cooked, transfer it to a plate and set it aside for just a moment. Add the remaining olive oil and butter to the same skillet, letting the butter melt and mingle with the oil. Toss in the sliced zucchini and yellow squash along with the remaining Italian seasoning and garlic powder. Cook, stirring frequently, for about 5 to 7 minutes or until the vegetables are tender but still hold a slight crunch—it’s this balance that keeps the dish lively and fresh.
Step 3: Bring It All Together with Cheese and Lemon
Now it’s time for a reunion party in the skillet. Return the cooked chicken to the pan with the tender squash and zucchini. Pour in the fresh lemon juice and sprinkle the Parmesan cheese and chopped parsley over the top. Toss everything gently but thoroughly to coat all the ingredients in the fragrant lemony, cheesy goodness. The heat from the skillet will melt the Parmesan just enough to create a luscious coating that hugs every piece.
Step 4: Garnish and Serve Hot
To finish, add a little extra Parmesan cheese and a sprinkle of lemon zest on top for added brightness and a gorgeous presentation. Serve your Skillet Lemon Parmesan Chicken with Zucchini and Squash Recipe piping hot straight from the pan—there’s something so satisfying about digging into a warm skillet brimming with fresh, vibrant flavors.
How to Serve Skillet Lemon Parmesan Chicken with Zucchini and Squash Recipe

Garnishes
Adding simple garnishes can elevate the meal and make it extra special. Fresh parsley sprinkled on top gives it a pop of color and a fresh herbal note, while an additional grating of Parmesan cheese adds a luxurious touch. A thin lemon wheel or extra lemon zest scattered over the dish brings that zesty appeal front and center.
Side Dishes
This dish is wonderfully versatile and pairs beautifully with many sides. Consider serving it alongside a light arugula salad tossed with a lemon vinaigrette to echo the citrus theme. Creamy mashed potatoes or fluffy quinoa can soak up any extra sauce, while crusty bread is perfect for mopping up every last bite.
Creative Ways to Present
For an Instagram-worthy presentation, try serving the dish in colorful cast iron skillets right at the table for a rustic effect. You can also plate the vegetables as a bed and fan the chicken pieces on top for a restaurant-style look. A drizzle of extra virgin olive oil or a sprig of fresh herbs adds that professional final flair.
Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers—which is rare!—store them in an airtight container in the refrigerator. They should stay fresh for up to 3 days, making it a convenient option for a tasty next-day meal.
Freezing
This Skillet Lemon Parmesan Chicken with Zucchini and Squash Recipe can be frozen, but the texture of zucchini and squash may soften slightly upon thawing. For best results, freeze the chicken and sauce separately from the vegetables and reheat gently to preserve the texture.
Reheating
To reheat, warm the dish in a skillet over low to medium heat, stirring occasionally until heated through. Adding a splash of olive oil or lemon juice can help refresh the flavors. Avoid the microwave if you can—it tends to affect the texture negatively.
FAQs
Can I use other types of cheese instead of Parmesan?
Absolutely! While Parmesan adds a unique salty nuttiness, you can substitute with Pecorino Romano for a sharper flavor or even Asiago. Just keep in mind they melt differently, so adjust accordingly.
What can I do if I don’t like zucchini or yellow squash?
No worries! This recipe is super adaptable. Try swapping in bell peppers, asparagus, or even green beans. All will soak up the lemon and seasoning beautifully.
Is this recipe suitable for meal prepping?
Yes, it works great for meal prepping as it reheats nicely. Just be mindful that the zucchini and squash might release some water over time, so slightly undercook them in the initial preparation if planning to prep ahead.
Can I make this recipe dairy-free?
Definitely! Just omit the butter and Parmesan, or replace Parmesan with a dairy-free cheese alternative or nutritional yeast to retain that cheesy flavor.
How can I make this dish more protein-packed?
Feel free to add cooked chickpeas or white beans to the skillet for extra protein and fiber. Or serve it alongside a grain like quinoa or farro to bulk it up and keep you full longer.
