Everything cooks in one baking dish, the chicken stays juicy, and the zucchini and tomatoes soak up all those savory juices. Feta, herbs, olives, and fresh lemon give it a bright Mediterranean flavor without making dinner complicated.

Why I Love This Recipe
I started making meals like this when I wanted the flavor of a full dinner without a sink full of dishes afterward. I especially love the moment the baking dish comes out of the oven. The tomatoes have burst, the chicken is golden, and there is a savory sauce sitting at the bottom of the dish.
Then the feta goes on while everything is still hot. It softens without completely melting, so you get creamy little bites mixed with the tomatoes, olives, zucchini, and chicken.
There are a few more reasons this one stays in my dinner rotation:
- Almost everything cooks in one 9×13-inch dish.
- There is no need to brown the chicken first.
- Zucchini and tomatoes cook in the chicken juices instead of needing a separate sauce.
- Lemon and fresh herbs keep the finished dish tasting bright.
- You can serve it alone for a lighter dinner or add rice, couscous, pasta, or bread for a bigger meal.
What You’ll Need
- 4 boneless, skinless chicken breasts, about 6 ounces each
- 2 medium zucchini, cut into 1/2-inch coins
- 2 cups cherry tomatoes
- 1/2 cup pitted Kalamata olives
- 3 tablespoons extra-virgin olive oil, divided
- 4 garlic cloves, minced
- 2 teaspoons dried oregano, divided
- 1 teaspoon garlic powder
- 1 teaspoon paprika
- 1 teaspoon kosher salt, divided, plus more if needed
- 1/2 teaspoon black pepper, divided, plus more if needed
- 1/4 teaspoon red pepper flakes, optional
- 3/4 cup crumbled feta cheese
- 2 tablespoons chopped fresh parsley or basil
- 1 lemon, cut into 4 wedges
Recipe and Instructions
Step 1: Preheat the Oven and Prep the Baking Dish
Preheat the oven to 400°F (204°C).
Pour 1 tablespoon extra-virgin olive oil into a 9×13-inch baking dish. Spread the oil across the bottom with a clean hand or paper towel. Make sure the bottom has a thin, even coating.
Step 2: Season the Chicken
Pat 4 boneless, skinless chicken breasts, about 6 ounces each, dry with paper towels.
Season both sides with 1 teaspoon garlic powder, 1 teaspoon paprika, 1 teaspoon dried oregano, 1/2 teaspoon kosher salt, and 1/4 teaspoon black pepper.
Place the seasoned chicken on a clean plate while you prepare the vegetables.
Step 3: Toss the Vegetables in the Baking Dish
Add 2 medium zucchini cut into 1/2-inch coins, 2 cups cherry tomatoes, and 1/2 cup pitted Kalamata olives to the oiled baking dish.
Drizzle with the remaining 2 tablespoons extra-virgin olive oil.
Add 4 minced garlic cloves, the remaining 1 teaspoon dried oregano, the remaining 1/2 teaspoon kosher salt, the remaining 1/4 teaspoon black pepper, and 1/4 teaspoon red pepper flakes if using.
Toss everything right in the baking dish until the vegetables are evenly coated with oil and seasoning.
Step 4: Arrange the Chicken
Place the 4 seasoned chicken breasts on top of the vegetable mixture. Space them apart so hot air can move around each piece.
Gently press the chicken down into the zucchini, cherry tomatoes, Kalamata olives, garlic, olive oil, and seasonings. You want the chicken nestled into the vegetables instead of sitting high above them.
Step 5: Bake Until the Chicken Is Done
Place the baking dish in the 400°F oven. Bake for 30 to 35 minutes.
Check the thickest part of each chicken breast with an instant-read thermometer. The chicken is ready when it reaches 165°F (74°C).
The zucchini should be tender with lightly golden edges. The tomatoes should look soft and burst, and the chicken should be golden on top.
Step 6: Add the Feta and Rest
Carefully remove the baking dish from the oven.
Immediately scatter 3/4 cup crumbled feta cheese over the hot chicken and vegetables.
Let everything rest for 5 minutes. This gives the chicken juices time to settle and lets the feta soften from the heat.
Step 7: Garnish and Serve
After the 5-minute rest, sprinkle 2 tablespoons chopped fresh parsley or basil over the entire dish.
Serve with 1 lemon cut into 4 wedges. Give each serving a lemon wedge so the juice can be squeezed over the chicken and vegetables just before eating.
Why This Recipe Works (Quick Science)
Chicken breasts can dry out when they cook too long. Baking them with juicy tomatoes and zucchini creates a moist cooking environment. Checking for 165°F helps you know when the chicken is safely cooked without guessing.
The salt also helps season the chicken all the way through the surface, while olive oil helps the seasonings stick and encourages browning.
Zucchini contains a lot of water. Cutting it into 1/2-inch coins makes the pieces thick enough to become tender without disappearing into mush.
Cherry tomatoes release sweet, acidic juices as they burst. Those juices mix with olive oil, chicken juices, garlic, oregano, and feta to create a simple sauce right in the baking dish.
The lemon goes on at the end because fresh acid wakes up rich and salty flavors. It makes the feta, olives, chicken, and olive oil taste brighter.
Pro Tips
- Try to use chicken breasts that are close to the same size. They will finish cooking at about the same time.
- Don’t cut the zucchini too thin. About 1/2 inch is just right for this baking time.
- Use a meat thermometer instead of cutting into the chicken again and again. This helps keep the juices inside.
- Add the feta after baking. It stays creamy and gives you better texture than feta that has baked for the full 30 minutes.
- If one chicken breast is much thicker than the others, gently pound the thick end so it has a more even thickness.
Tools You’ll Need
- 9×13-inch baking dish
- Cutting board
- Chef’s knife
- Measuring cups
- Measuring spoons
- Paper towels
- Large spoon
- Instant-read meat thermometer
- Oven mitts
- Serving spoon or spatula
Common Mistakes
- Cutting zucchini too thin: Thin slices can become very soft. Stick with 1/2-inch coins.
- Crowding the chicken together: Leave a little room between the breasts so they cook more evenly.
- Using very different chicken sizes: A small breast may dry out before a large one reaches 165°F.
- Skipping the thermometer: Cooking time is only a guide. Chicken thickness and ovens vary.
- Adding too much extra salt: Feta and Kalamata olives are already salty. Taste the finished dish before adding more.
- Skipping the rest: Give the chicken 5 minutes before serving so more of its juice stays in the meat.
Substitutions and Variations
- Swap chicken breasts for boneless, skinless chicken thighs. The cooking time may change, so cook to a safe internal temperature.
- Replace Kalamata olives with another pitted olive you enjoy.
- Use grape tomatoes instead of cherry tomatoes.
- Try goat cheese in place of feta for a softer, tangier finish.
- Leave out the red pepper flakes for no added heat.
- Add sliced red onion or bell pepper if you want more vegetables.
- Use fresh oregano if you have it, but add some near the end for the freshest flavor.
Make-Ahead Tips
You can cut the zucchini, mince the garlic, and measure the seasonings up to 1 day ahead. Keep everything covered in the refrigerator.
You can also season the chicken several hours before cooking and refrigerate it in a covered container.
For the best texture, wait to combine the zucchini, tomatoes, salt, and olive oil until you are ready to bake. Salt pulls water from zucchini, so mixing it too early can make the dish watery.
What to Serve With
This bake has chicken and plenty of vegetables, so it can be a full meal on its own. For a heartier dinner, try it with:
- Couscous
- Rice or lemon rice
- Orzo
- Quinoa
- Warm pita bread
- Crusty bread for soaking up the juices
- A simple green salad
- Roasted potatoes
- Hummus and pita

Leftovers and Storage
Let leftovers cool, then place them in an airtight container. Refrigerate for up to 3 to 4 days.
For reheating, cover a portion and warm it gently in the microwave until hot. You can also put leftovers in a small baking dish, cover with foil, and heat at 350°F until warmed through.
The zucchini will become softer after storage, but the flavors are still great the next day.
You can freeze the cooked chicken, but the zucchini and tomatoes may become quite soft after thawing. For that reason, I prefer this recipe fresh or refrigerated rather than frozen.
FAQ
Q: Can I use chicken thighs instead of chicken breasts?
A: Yes. Boneless, skinless chicken thighs work well. Their cooking time may be different, so use a meat thermometer to check for doneness.
Q: Why did my bake turn out watery?
A: Zucchini and tomatoes naturally release water as they cook. Very thin zucchini slices, salted vegetables that sat too long before baking, or crowded vegetables can create even more liquid. Some juice in the bottom is normal and tastes great spooned over rice or couscous.
Q: Do I need to peel the zucchini?
A: No. Leave the peel on. It adds color and helps the zucchini coins hold their shape.
Q: Can I leave out the olives?
A: Yes. The bake will have a little less salty, briny flavor, but it will still work.
Q: Can I add the feta before baking?
A: You can, but adding it afterward gives it a softer, fresher texture. The heat from the finished bake is enough to warm it.
Q: How do I know the chicken is cooked?
A: Check the thickest part with an instant-read thermometer. The chicken should reach 165°F (74°C).
Q: Can I prepare the whole dish the night before?
A: I would prep the ingredients separately instead. Zucchini starts releasing water after it is salted, so assembling everything right before baking gives you better texture.
Final Thoughts
This Mediterranean Chicken Zucchini Bake turns simple ingredients into a colorful, filling dinner with very little cleanup. The juicy chicken, tender zucchini, burst tomatoes, salty olives, creamy feta, and fresh lemon all work together without needing a separate sauce.
Serve it straight from the baking dish with your favorite side, and don’t forget to spoon some of those tomato and chicken juices over each serving. If you make it, leave a comment and share how it turned out or any questions you had along the way.
