Ingredients You’ll Need

- 1 lb ground turkey: The lean protein base that keeps this casserole hearty without being heavy.
- 2 medium zucchinis, sliced: Adds moisture, freshness, and a gentle crunch to every bite.
- 1 cup shredded mozzarella cheese: Melts perfectly to create that irresistible golden, gooey topping.
- 1/2 cup chopped onion: Provides sweetness and depth when sautéed to tender perfection.
- 2 cloves garlic, minced: Infuses the casserole with aromatic warmth and subtle bite.
- 1 can (14 oz) diced tomatoes, drained: Offers juicy pops of flavor and balances the savory components.
- 1 tsp dried Italian herbs: Brings a fragrant Mediterranean flair that ties all the ingredients together.
- 1/2 tsp salt: Enhances all the natural flavors without overpowering.
- 1/4 tsp black pepper: Delivers a gentle, spicy kick to brighten the dish.
- 1 tbsp olive oil: Helps sauté the aromatics while adding richness.
How to Make Ground Turkey Zucchini Casserole
Step 1: Preheat and Prepare
Start by heating your oven to 375°F (190°C). Grease a 9×13-inch baking dish with olive oil to prevent sticking and ensure your casserole bakes evenly with a lovely crust forming on top.
Step 2: Sauté Onions and Garlic
In a large skillet over medium heat, warm the olive oil and gently sauté the chopped onion and minced garlic until they turn fragrant and translucent—about 2 minutes. This simple step awakens the flavors and lays a savory foundation for the entire dish.
Step 3: Brown the Ground Turkey
Add the ground turkey to the skillet. Cook it thoroughly, breaking it apart with your spoon until it’s no longer pink and has a light golden color—about 5 to 6 minutes. Browning not only locks in flavor but also adds a subtle nuttiness that complements the zucchini beautifully.
Step 4: Mix in Tomatoes and Herbs
Stir in the drained diced tomatoes, dried Italian herbs, salt, and black pepper. Allow everything to simmer together for 3 to 4 minutes, giving the flavors a chance to blend and the turkey to soak up the aromatic herby goodness.
Step 5: Layer the Casserole
In your prepared baking dish, arrange half of the sliced zucchini evenly across the bottom. Spread half of the turkey and tomato mixture on top, then sprinkle with half of the shredded mozzarella. Repeat these layers once more to build a perfectly balanced casserole with lovely texture and color contrasts.
Step 6: Bake to Perfection
Pop the casserole into the oven and bake uncovered for 30 to 35 minutes. Look for bubbling edges and beautifully golden cheese on top. When done, let it cool for about 5 minutes to set before slicing. This rest allows the layers to hold together better, making each serving neat and satisfying.
How to Serve Ground Turkey Zucchini Casserole

Garnishes
To elevate your Ground Turkey Zucchini Casserole, sprinkle fresh chopped basil or parsley on top just before serving. A light drizzle of extra virgin olive oil or a scattering of chili flakes can brighten the dish and add a lovely finishing touch.
Side Dishes
This casserole pairs wonderfully with crisp green salads or fluffy quinoa to balance the hearty, cheesy texture. Roasted garlic bread or a simple cucumber salad can also add fresh, contrasting notes that keep the meal dynamic and satisfying.
Creative Ways to Present
For a fun twist at gatherings, serve the casserole in individual ramekins or mini casseroles, allowing everyone their own personal portion. Alternatively, scoop it over a bed of creamy mashed potatoes or polenta for a rich and comforting experience.
Make Ahead and Storage
Storing Leftovers
Leftover Ground Turkey Zucchini Casserole keeps beautifully in an airtight container in the refrigerator for up to 3 days. This makes it a great option for easy meal prep—just reheat and enjoy!
Freezing
If you want to stash some for even later, freeze the casserole in a freezer-safe dish or tightly wrapped in foil for up to 2 months. Remember to thaw overnight in the fridge before reheating to keep that tender texture intact.
Reheating
To reheat, cover the casserole with foil and warm it in the oven at 350°F (175°C) for about 20 minutes until heated through. You can also microwave single servings on medium power, covering the dish to retain moisture for a quick lunch or dinner fix.
FAQs
Can I use ground chicken instead of ground turkey?
Absolutely! Ground chicken will work just as well, keeping the dish light and protein-rich while offering a slightly different flavor profile.
Do I need to peel the zucchinis?
No need to peel them. The skin adds vibrant color and extra nutrients, and it softens nicely during baking.
Can I add other vegetables to this casserole?
Yes, feel free to get creative! Adding diced bell peppers, mushrooms, or spinach can boost the veggie content and add more layers of taste.
Is this casserole gluten-free?
Yes, as written, this recipe contains no gluten ingredients, making it suitable for gluten-free diets.
How many servings does this casserole make?
This recipe makes approximately 4 generous servings, perfect for a family dinner or leftovers to enjoy the next day.
