How to Make Tasty Chicken Breast with Zucchini and Squash
Step 1: Prep the Chicken and Veggies
Slice the chicken breasts horizontally into thinner cutlets if they look thick. Pat them dry with paper towels on both sides. Season both sides with salt, pepper, half the Italian seasoning, and half the paprika.
Slice zucchini and yellow squash into half moons about ¼ inch thick. Slice the red onion and bell pepper if you use them. Keep veggies in a large bowl so you can toss them easily.
Step 2: Season the Vegetables
Drizzle 1 tablespoon olive oil over the veggies in the bowl. Add the rest of the Italian seasoning, paprika, a pinch of salt, black pepper, and the minced garlic. Toss everything until the zucchini and squash look lightly coated.
Add lemon zest and red pepper flakes if you want a little kick. Toss again and set the bowl aside while you cook the chicken. This short rest lets the salt start to draw out flavor from the veggies.
Step 3: Sear the Chicken
Heat 1 to 1½ tablespoons olive oil in the large skillet over medium high heat. When the oil shimmers, lay the chicken cutlets in a single layer. Leave a little space between pieces so they brown nicely.
Cook the chicken about 4 to 5 minutes on the first side until the edges look opaque and golden. Flip and cook another 3 to 4 minutes until the thickest part reaches 165°F on the thermometer. Move cooked chicken to a plate and cover it loosely with foil.
Step 4: Cook the Zucchini and Squash
Keep the skillet on medium heat and add the remaining olive oil if the pan looks dry. Pour the seasoned zucchini, squash, onion, and bell pepper into the pan. Spread them out so they sit in one layer as much as possible.
Let the veggies sit untouched for 2 minutes so they get some color. Stir and continue to cook 4 to 6 more minutes until they turn tender but not mushy and the edges start to brown. Squeeze in the lemon juice and scrape up any browned bits from the bottom of the pan.
Step 5: Bring It All Together
Slice the cooked chicken into strips or bite size pieces. Add the chicken back into the skillet with the veggies. Toss gently so the chicken picks up the garlicky lemony juices.
Sprinkle Parmesan cheese over the top and let it melt for 1 minute. Taste and adjust salt, pepper, or lemon juice. Finish with chopped parsley or basil and serve hot.

Storage Success
Cool leftovers until they reach room temperature, then store them in an airtight container in the fridge for up to 3 to 4 days. Reheat gently in a skillet over medium heat with a splash of water or broth so the chicken stays moist. You can also reheat in the microwave in short bursts and stir between rounds. If the veggies soften a bit after storage, they still taste great in grain bowls or stuffed into wraps.

Ingredients
Method
- Slice the chicken breasts horizontally into thinner cutlets if they are thick. Pat dry on both sides with paper towels. Season both sides with salt, pepper, half of the Italian seasoning, and half of the paprika.
- Slice the zucchini and yellow squash into 1/4-inch-thick half moons. Thinly slice the red onion and red bell pepper if using. Place all vegetables into a large bowl.
- Drizzle 1 tablespoon of the olive oil over the vegetables. Add the remaining Italian seasoning, remaining paprika, a pinch of salt and black pepper, and the minced garlic. Toss until the vegetables are lightly coated. Add lemon zest and red pepper flakes if using, toss again, and set aside.
- Heat 1 to 1 1/2 tablespoons olive oil in a large skillet over medium-high heat until the oil shimmers. Add the chicken cutlets in a single layer without crowding. Cook for 4 to 5 minutes on the first side until the edges look opaque and golden. Flip and cook for another 3 to 4 minutes, or until the thickest part reaches 165°F. Transfer the cooked chicken to a plate and cover loosely with foil.
- Reduce the heat to medium. If the skillet looks dry, add the remaining olive oil. Add the seasoned zucchini, yellow squash, onion, and bell pepper to the pan and spread into as even a layer as possible. Let cook undisturbed for about 2 minutes to develop color, then stir and continue cooking for 4 to 6 minutes, until the vegetables are tender but not mushy and the edges are browned. Add the lemon juice and scrape up any browned bits from the bottom of the pan.
- Slice the cooked chicken into strips or bite-size pieces. Return the chicken and any accumulated juices to the skillet with the vegetables and toss gently to combine so the chicken is coated in the pan juices.
- Sprinkle the Parmesan over the top and let it melt for about 1 minute. Taste and adjust seasoning with more salt, pepper, or lemon juice as desired. Finish with chopped parsley or basil and serve hot.
