- 1 lb ground turkey: Choose lean for a light, protein-rich base with great texture.
- 3 medium zucchinis, thinly sliced: Fresh and slightly crisp, they soak up the flavors while keeping the dish moist.

- 2 cloves garlic, minced: This seasoning powerhouse brings aromatic depth.
- 1 cup shredded mozzarella cheese: Melts beautifully for that gooey, creamy layer everyone loves.
- 1/2 cup grated Parmesan cheese: Sprinkles a punch of sharp, nutty flavor on top.
- 1 cup marinara sauce: Rich and tomatoey, it ties the whole casserole together.
- 1 teaspoon dried Italian seasoning: Introduces fragrant herbs for that classic Italian flair.
- 1/2 teaspoon salt: Balances all the flavors perfectly.
- 1/4 teaspoon black pepper: Adds just the right amount of spice.
- 1 tablespoon olive oil: Essential for sautéing and infusing flavor.
- Fresh basil or parsley for garnish (optional): Brightens the final presentation and flavor.
How to Make Savory Ground Turkey Zucchini Casserole Recipe
Step 1: Preheat and Prep
Start by preheating your oven to 375°F (190°C). This sets the perfect temperature to cook your casserole evenly, ensuring the cheese melts and browns just right.
Step 2: Sauté Aromatics
In a large skillet, heat the olive oil over medium heat. Toss in the diced onion and minced garlic, cooking until they soften and become translucent, about 3 minutes. This builds a flavorful foundation that’ll infuse the ground turkey.
Step 3: Brown the Ground Turkey
Add the ground turkey to the skillet, breaking it apart with a spatula as it cooks. Let it brown completely and lose any pink color, which usually takes around 6 to 8 minutes. Season with salt, pepper, and dried Italian seasoning to amplify those savory notes.
Step 4: Combine with Marinara Sauce
Pour the marinara sauce into the pan and stir it into the turkey mixture. Let it simmer together for an additional 2 minutes, enhancing the cohesiveness of the flavors before taking it off the heat.
Step 5: Assemble the Layers
Grease a 9×13-inch baking dish lightly with olive oil or cooking spray. Start by laying out half of the thinly sliced zucchinis in an even layer. This creates a fresh, tender base for the savory toppings.
Step 6: Layer the Turkey and Cheese
Spread half of the turkey and marinara mixture evenly over the zucchini layer. Follow up by sprinkling half of the mozzarella and Parmesan cheese on top. This mix ensures creamy, cheesy pockets inside the casserole.
Step 7: Repeat the Process
Place the remaining zucchini slices on top, then the rest of the turkey mixture. Finish with the last bit of shredded mozzarella and Parmesan cheese, building that irresistible golden crust during baking.
Step 8: Bake Covered
Cover the dish tightly with foil to lock in moisture and bake in the preheated oven for 30 minutes. This allows the zucchini to soften and the flavors to marry beautifully.
Step 9: Uncover and Brown
Remove the foil carefully and put the casserole back in the oven for an extra 10 minutes. This step gives the cheese its chance to bubble and turn a gorgeous golden brown that’s as tasty as it looks.
Step 10: Cool and Garnish
Let the casserole cool for a few minutes once it’s done so the layers settle nicely and cutting into it won’t be messy. Adding fresh basil or parsley on top adds a lovely pop of color and fresh flavor that brightens the dish even more.
