Ingredients You’ll Need
The beauty of the Savory Ground Turkey Zucchini Casserole Recipe lies in its simplicity. Each ingredient plays a vital role in creating layers of flavor and texture—from the tender zucchini to the well-seasoned turkey and the cheesy topping that crisps up perfectly in the oven.
- 1 lb ground turkey: A lean protein base that keeps the casserole hearty but light.

- 1/2 cup grated Parmesan cheese: Adds a sharp, nutty contrast to the mild mozzarella.
- 1 cup marinara sauce: Brings acidity and herbs, tying all components together with a classic Italian flair.
- 1 teaspoon dried Italian seasoning: A fragrant blend that infuses the dish with warmth and complexity.
- 1/2 teaspoon salt: Enhances all the flavors without overpowering.

How to Make Savory Ground Turkey Zucchini Casserole Recipe
Step 1: Prepare Your Oven and Ingredients
Begin by preheating your oven to 375°F (190°C). This ensures it’s hot and ready when your casserole is assembled, guaranteeing a perfectly cooked dish. While the oven warms up, thinly slice your zucchinis and dice the onion. Getting your ingredients ready upfront makes the cooking process so smooth and fun.
Step 2: Sauté Onion and Garlic
Heat 1 tablespoon of olive oil in a large skillet over medium heat. Toss in your diced onions and minced garlic, cooking just until they turn translucent and fragrant—about 3 minutes. This simple step builds a flavorful foundation that will make your casserole sing.
Step 3: Brown the Ground Turkey
Add the ground turkey to the skillet, breaking it apart with your spatula. Let it cook until it’s no longer pink, roughly 6-8 minutes. Season with salt, black pepper, and your teaspoon of dried Italian seasoning to infuse every bite with that classic herb blend we all adore.
Step 4: Stir in Marinara Sauce
Once the turkey is cooked through, pour in the marinara sauce and stir everything together. Allow it to simmer gently for about 2 minutes so the flavors can mingle before you remove the skillet from heat. This sauce-turkey mix is the heart of your casserole’s savory goodness.
Step 5: Layer the Zucchini
Grease a 9×13-inch baking dish to prevent sticking. Arrange half of the sliced zucchinis in an even layer at the bottom of the dish. This layer acts as a tender, veggie-packed base that will soak up all the delicious juices as it bakes.
Step 6: Add Turkey Mixture and Cheese
Spoon half of your turkey and marinara mixture over the zucchini layer, spreading it evenly. Follow this by sprinkling half of the shredded mozzarella and grated Parmesan cheeses on top. This layering ensures every bite has a perfect balance of meat, veggies, and cheese.
Step 7: Repeat the Layers
Repeat the layering process: zucchini, turkey mixture, mozzarella, and Parmesan cheese. This builds a beautiful, hearty casserole that is as pleasing to the eye as it is to the palate.
Step 8: Bake Covered
Cover the casserole dish with aluminum foil and bake in your preheated oven for 30 minutes. Covering helps the zucchini soften thoroughly while keeping the moisture locked in.
Step 9: Finish Baking Uncovered
Remove the foil and continue baking for an additional 10 minutes. This step lets the cheese bubble up and turn a gorgeous golden brown, creating a delightful crust that’s a perfect contrast to the creamy inside.
Step 10: Rest and Garnish
Allow the casserole to cool slightly out of the oven before serving. This resting time helps the layers set, making it easier to cut perfect portions. Garnish with fresh basil or parsley for a burst of color and an aromatic finish.
How to Serve Savory Ground Turkey Zucchini Casserole Recipe

Garnishes
Finishing this casserole with fresh herbs such as basil or parsley isn’t just for looks—it adds a bright, fresh flavor that lifts the entire dish. A light sprinkle of extra Parmesan cheese on top before serving is another great way to add a salty, savory note.
Side Dishes
This casserole is quite filling on its own, but pairing it with a crisp green salad or roasted vegetables can add extra texture and color to your meal. Something simple like garlic bread or a light quinoa salad also pairs beautifully without overwhelming the subtle flavors of the casserole.
Creative Ways to Present
For a fun twist, serve this Savory Ground Turkey Zucchini Casserole Recipe in individual ramekins. This personalized touch makes it perfect for dinner parties or meal prepping. You could also top each serving with a dollop of ricotta or a crack of freshly ground black pepper to add an extra flavor dimension.
Make Ahead and Storage
Storing Leftovers
Leftover casserole can be stored in an airtight container in the refrigerator for up to 4 days. It keeps well, and the flavors actually deepen as it sits, making for even tastier meals throughout the week.
Freezing
You can freeze portions of the casserole for up to 2 months. Just wrap individual servings tightly in plastic wrap and then foil, or use freezer-safe containers. When you’re ready, thaw overnight in the fridge for the best texture and flavor.
Reheating
To reheat, warm leftovers gently in the oven at 350°F (175°C) for about 15-20 minutes or microwave on medium heat until heated through. Cover with foil to prevent the top from drying out while reheating in the oven.
FAQs
Can I use ground chicken instead of turkey?
Absolutely! Ground chicken is a great substitute and will work well with the flavors and texture of this casserole. Just keep an eye on cooking time as it may vary slightly.
Is this recipe gluten-free?
Yes, this casserole is naturally gluten-free as long as your marinara sauce does not contain any gluten-containing ingredients. Always check the label to be sure!
Can I add other vegetables to this casserole?
Definitely. Feel free to mix in sliced mushrooms, bell peppers, or spinach for added nutrition and flavor variety. Just adjust layering to accommodate extra ingredients.
