Ingredients You’ll Need
This recipe is a celebration of fresh, staple ingredients—each one thoughtfully chosen to highlight a specific texture or flavor. You don’t need anything fancy, just a few reliable groceries that absolutely sing when layered together in this Ground Turkey Zucchini Casserole.
- Ground turkey: Lean and mild, it soaks up the Italian spices and keeps things protein-packed without feeling heavy.
- Zucchinis: Sliced into coins, they add a delightful bite and a pop of garden green throughout each forkful.
- Shredded mozzarella cheese: Melty and golden, this cheese blankets the casserole and ties all the flavors together.
- Chopped onion: Sautéed for sweetness and depth, it forms the aromatic base of the dish.
- Minced garlic: Just a couple of cloves bring warmth and classic Italian flair.
- Diced tomatoes (canned, drained): Tangy and juicy, they keep the casserole moist and add layers of flavor.
- Dried Italian herbs: A blend of oregano, basil, and more—it’s like a shortcut to that slow-cooked taste.
- Salt: Essential for seasoning the whole dish, making each ingredient pop.
- Black pepper: Adds a gentle kick that rounds out the spices.
- Olive oil: For sautéing and prepping your baking dish, delivering a hint of richness.
How to Make Ground Turkey Zucchini Casserole
Step 1: Prep Your Baking Dish
Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish lightly with olive oil. This not only prevents sticking but also adds an extra layer of flavor to the finished casserole.
Step 2: Sauté the Onion and Garlic
Heat olive oil in a large skillet over medium heat. Add the chopped onion and minced garlic, sautéing for about 2 minutes until everything turns fragrant and starts to soften. This gives your casserole a deeply savory foundation.
Step 3: Brown the Ground Turkey
Add the ground turkey straight into the skillet. Break it up as it cooks so you have small, even pieces. Continue to cook for 5 to 6 minutes until all the pink is gone and the turkey is lightly browned—this builds so much flavor!
Step 4: Simmer With Tomatoes and Spices
Stir in the drained diced tomatoes, dried Italian herbs, salt, and black pepper. Let everything simmer together for another 3 to 4 minutes. The turkey will absorb the garlicky tomato goodness, making every bite mouthwatering.
Step 5: Layer the Casserole
Spread half of the sliced zucchini in an even layer at the bottom of your prepared baking dish. Next, scoop on half of your turkey mixture and sprinkle it with half of the mozzarella cheese. Repeat the layers once more—zucchini, turkey mixture, and then the rest of the cheese on top. This guarantees a delicious cross-section of flavors in every serving.
Step 6: Bake Until Golden and Bubbling
Pop the dish in the oven, uncovered, and bake for 30 to 35 minutes. You’ll know it’s ready when the cheese is golden, and the casserole bubbles with savory aroma. Let it cool for a quick five minutes before digging in to make serving easier.
How to Serve Ground Turkey Zucchini Casserole

Garnishes
For an extra pop of color and flavor, sprinkle the top of your casserole with freshly chopped parsley or basil right before serving. A quick turn of cracked black pepper or a light grating of parmesan across the top also takes this Ground Turkey Zucchini Casserole from cozy to company-worthy in seconds.
Side Dishes
Though the casserole is hearty enough to stand on its own, it pairs beautifully with a crisp green salad or roasted vegetables. Warm garlic bread or a scoop of herbed quinoa can help soak up every bit of that rich sauce, making your meal feel balanced and complete.
Creative Ways to Present
For something playful, portion the Ground Turkey Zucchini Casserole into individual ramekins for dinner parties or meal prep. You could also serve it over a bed of spaghetti squash or alongside zucchini noodles, doubling up on the veggie goodness with a fun twist.
Make Ahead and Storage
Storing Leftovers
Any leftover Ground Turkey Zucchini Casserole can be kept in an airtight container in your refrigerator for up to 4 days. The flavors often deepen as they meld, so a scoop heated up the next day might taste even better!
Freezing
This casserole is freezer-friendly! Let it cool completely, then wrap tightly or store in a freezer-safe container. It’ll keep well for up to 3 months. For easiest reheating, slice it into portions before freezing so you can pull out exactly what you need.
Reheating
To reheat, place the casserole (or individual slices) in a baking dish, cover with foil, and warm in a 350°F oven for 20 minutes or until hot. If you’re short on time, the microwave works too—just cover your portion and heat in short bursts to avoid drying it out.
FAQs
Can I substitute ground chicken for turkey?
Absolutely! Ground chicken works just as beautifully in this casserole. It will bring a slightly different flavor but will still be just as tender and delicious.
Will the zucchini turn mushy during baking?
No need to worry—the zucchini retains a nice bite when layered raw as outlined in this Ground Turkey Zucchini Casserole. If you prefer firmer zucchini, slice it a little thicker.
Can I add other vegetables?
Definitely! Chopped spinach, bell peppers, or mushrooms are superb add-ins. Just be mindful not to overfill the dish, or you might need to adjust baking times.
What if I want it spicier?
If you like a little kick, add a pinch of red pepper flakes or a finely chopped jalapeño when you sauté the onion and garlic. You’ll have a spicier, zippier version of Ground Turkey Zucchini Casserole.
How do I keep the casserole from getting watery?
Make sure to drain the diced tomatoes thoroughly. Also, don’t salt the zucchini until it’s layered in the dish, as pre-salting can draw out extra moisture.
Final Thoughts
If you’re craving something hearty yet wholesome, this Ground Turkey Zucchini Casserole deserves a spot on your table. I hope you’ll give it a try—it’s one of those magical recipes that brings comfort and joy with every bite!
