Ingredients and Substitutions

You only need a few simple ingredients for this easy recipe. They should be easy to find in your grocery store if you don’t have them at home. You can find complete ingredients in the printable recipe card below.

  • Chicken — thin boneless skinless chicken breasts or chicken breast halves. You can sub chicken thighs if you like.
  • Zucchini — I used 2 small zucchini sliced into half moons
  • Yellow squash — I used 2 small squash sliced into smaller pieces
  • Seasonings — sea salt, black pepper, garlic powder, Italian seasoning blend
  • Olive oil
  • Grape tomatoes — optional, but pairs really well with the flavors here. Red bell peppers are a great substitute.
  • Parmesan cheese — optional, but adds extra flavor. Shredded mozzarella cheese is another option to make cheesy chicken.

How to Make Baked Chicken and Zucchini on One Sheet Pan

The key to getting the chicken breasts and vegetables to cook quickly and evenly together is to slice the chicken in half lengthwise. In other words, butterfly the chicken.

Then, season it, and place it on a large rimmed baking sheet, along with olive oil.

Next, add some sliced zucchini and yellow squash. Then, throw in a few grape tomatoes, season everything, and drizzle a little more olive oil on top.

I added grape tomatoes since we have a lot of them in the garden. These burst tomatoes shrivel up slightly and make a delicious light sauce as they cook.

If you don’t have any, don’t worry about it — the chicken is just as delicious without them.

Cook Time

Bake the chicken for 15-20 minutes or until the chicken reaches an internal temperature of 165 degrees f. For best results, use an instant-read thermometer.

When done, the summer vegetables should be fork tender and the chicken should be light golden brown.

What to Serve with Chicken Zucchini Bake

You can add a little shredded Parmesan cheese and a bit of butter and fresh parsley at the end for even more flavor!

This easy chicken bake is a delicious low carb recipe by itself, but jasmine rice or brown rice make a delicious side dish. You can also throw in some diced potatoes or diced sweet potatoes and crusty bread for a complete meal.

How to Store and Reheat

Refrigerate leftover chicken and vegetables in an airtight container for up to 4 days. Freeze the chicken for up to 3 months in a freezer-safe container.

Reheat the chicken in your microwave or in the oven.

Cooking Tips

Use parchment paper or aluminum foil on the baking sheet for easy clean-up.

Use chicken pieces that are about the same size so they cook evenly. You may need to pound them lightly with a meat mallet if they are not even.

Choose small or medium zucchini for best flavor. Large zucchini tends to be bitter.
