There’s something about the smell of lemon and butter sizzling in a pan that just fixes everything. Lemon Parmesan Chicken Zucchini and Squash is one of those dinners that comes together fast, tastes like spring, and leaves you feeling good instead of stuffed.
I tested this recipe back in March when I was craving something lighter but still comfortingnot salad, not soup, just real food that didn’t feel heavy. After a long day, I need dinner to be easy but still taste homemade, and this one delivers every single time. The trick is getting a good sear on the chicken first so the pan stays hot enough to caramelize the squash without turning it mushy. I’ve been blogging for over a decade, and this is still the kind of meal I come back to when I’m tired but don’t want to compromise on flavor.

Lemon Parmesan Chicken Zucchini and Squash Easy Weeknight Dinner
This Lemon Parmesan Chicken with Zucchini and Squash is a bright and tasty one pan chicken dish perfect for an easy dinner or weeknight meal. It’s a simple chicken recipe that the whole family will enjoy and makes a fantastic family dinner option. Packed with fresh flavors and minimal cleanup, it’s ideal for busy evenings.
10 oz. (2 small) zucchini, sliced and halved if wider
10 oz. (2 small) yellow squash, sliced and halved if wider
1/3 cup finely shredded parmesan, or more to taste
2 Tbsp chopped fresh parsley
2 Tbsp fresh lemon juice
Method
Warm 1 tablespoon of olive oil in a 12-inch non-stick pan over medium-high heat. Pat the chicken dry with paper towels and season it generously with salt, pepper, 2 teaspoons of Italian seasoning, half of the garlic powder, onion powder, and lemon zest. Toss well to coat the pieces evenly. Add butter to the oil and let it melt, then place the chicken in the pan. Cook for 3 minutes before turning the pieces over, then continue cooking until the chicken is fully cooked through (internal temperature at 165°F), about 3 minutes more. Remove the chicken from the skillet and cover with foil to keep warm. In the same skillet, add the remaining olive oil and butter and heat over medium-high. Toss in the zucchini and yellow squash and season with salt, the remaining Italian seasoning, and the remaining garlic powder. Stir occasionally as the veggies cook until just tender, roughly 4 minutes. Return the chicken to the vegetable mixture and pour in the fresh lemon juice, tossing everything together gently. Finish by sprinkling the parmesan cheese and chopped parsley over the top. Serve right away with extra parmesan and lemon zest if you like.

FAQs (Lemon Parmesan Chicken Zucchini and Squash)
Can I use frozen vegetables for this recipe?
Fresh zucchini and squash work best since frozen versions release too much water when cooked. If using frozen, thaw completely and pat dry with paper towels first. The texture won’t be as crisp, but the flavor will still be delicious.
How long does this dish keep in the refrigerator?
This meal stays fresh in the fridge for up to 3 days when stored in an airtight container. The vegetables may soften slightly, but it reheats well in a skillet over medium heat. Add a squeeze of fresh lemon juice when reheating to brighten the flavors.
What type of Parmesan cheese works best?
Freshly grated Parmigiano-Reggiano gives the best flavor and melts beautifully into the dish. Pre-grated parmesan from the store works too, but fresh gives a richer taste. Grate it yourself right before cooking for maximum flavor impact.
Can I substitute chicken thighs for chicken breast?
Absolutely! Chicken thighs add extra flavor and stay more tender during cooking. Cut them into similar-sized pieces and cook for an additional 2-3 minutes to ensure they’re fully done. The extra fat from thighs makes this recipe even more satisfying.
Should I remove the seeds from the squash?
For yellow squash, the seeds are small and tender, so you can leave them in. If using larger summer squash with bigger seeds, scoop them out for better texture. The key is cutting the squash into uniform pieces so everything cooks evenly.

One of my favorite tricks is squeezing a little extra lemon over the top right before servingit wakes everything up. If you want to stretch this into more servings, toss it with angel hair pasta or spoon it over fluffy rice. Leftovers reheat beautifully in a skillet with a splash of chicken broth to keep things moist. And if you have fresh basil lying around, tear some over the top instead of parsleyit’s a little swap I learned from my aunt’s kitchen that makes the whole dish smell incredible.
