How to Make Skillet Lemon Parmesan Chicken with Zucchini and Squash Recipe
Step 1: Cook the Chicken with Seasonings
Start by heating 1 tablespoon of olive oil in a large skillet over medium heat. Meanwhile, season your diced chicken pieces generously with salt, pepper, half of the Italian seasoning, half of the garlic powder, onion powder, and 1 teaspoon of fresh lemon zest. When the oil is hot, add the chicken in a single layer. Let it cook undisturbed for a bit so it develops a beautiful golden crust, then stir occasionally until the chicken is fully cooked and juicy inside. This layer of seasoning creates a flavorful foundation that will shine through in every bite.
Step 2: Sauté the Zucchini and Squash
Next, without cleaning the skillet, add the remaining olive oil and butter. Toss in the sliced zucchini and yellow squash, sprinkle with the rest of the Italian seasoning and garlic powder, and season with salt and pepper to taste. Sauté the vegetables, stirring gently, until they become tender but still hold a pleasant crunch. The butter enriches the veggies, while the seasoning ensures they’re bursting with flavor.
Step 3: Combine Chicken and Vegetables with Lemon and Parmesan
Now it’s time to reunite! Add the cooked chicken back to the skillet with the vegetables. Pour in the fresh lemon juice, sprinkle the Parmesan cheese evenly over the top, and add the chopped parsley. Carefully toss or stir everything together until the cheese melts gently and all the flavors meld beautifully. This step elevates the dish into something truly comforting and vibrant.
Step 4: Garnish and Serve Hot
Just before serving, add an extra pinch of Parmesan and a sprinkle of fresh lemon zest for a final burst of flavor and a lovely visual touch. Serve your Skillet Lemon Parmesan Chicken with Zucchini and Squash Recipe hot to enjoy all the fresh and melty magic at its best.

Creative Ways to Present
For a charming family-style presentation, serve straight from the skillet with colorful bowls of sides and garnishes arranged around the table. Alternatively, plate individual portions on square white dishes for a modern look, garnishing with microgreens or edible flowers to impress your guests.
Make Ahead and Storage
Storing Leftovers
Allow the skillet dish to cool fully before transferring leftovers to an airtight container. Refrigerate and enjoy within 3 to 4 days to preserve freshness and flavor.
Freezing
This recipe freezes well but for best texture, separate the chicken and vegetables before freezing. Use freezer-safe containers or bags, and consume within 2 months for optimal taste.
Reheating
Reheat leftovers gently in a skillet over medium-low heat to prevent drying out. Add a splash of water or broth if needed to keep the dish moist. A quick microwave reheating covered with a damp paper towel also works well.
FAQs
Can I use chicken thighs instead of chicken breasts?
Absolutely! Chicken thighs are juicier and more forgiving when cooking, making them a delicious alternative. Just adjust the cooking time slightly to ensure they are cooked through.
What if I only have one type of squash?
No worries at all! Using just zucchini or yellow squash still works wonderfully in this recipe. Each type has a mild flavor and tender texture that complements the chicken and seasonings beautifully.
Is Parmesan cheese necessary?
Using Parmesan adds a savory, nutty depth that really enhances the dish. If you don’t have Parmesan, you could try a similar hard cheese like Pecorino Romano or even a good quality grated Asiago.
Can I make this recipe dairy-free?
Yes! Substitute the butter with extra olive oil and omit or replace Parmesan with a dairy-free cheese alternative or nutritional yeast for a cheesy flavor.
How bright will the lemon flavor be?
The lemon zest and juice bring a fresh, lively brightness that balances the richness of the chicken and cheese without overpowering. If you love citrus, feel free to add a bit more zest or juice to your taste.
