Ingredients You’ll Need
This Savory Ground Turkey Zucchini Casserole Recipe calls for simple, wholesome ingredients that work together harmoniously. Each one plays a vital role—bringing freshness, richness, or seasoning to round out every bite with vibrant flavor and satisfying texture.
- 1 lb ground turkey: Lean yet juicy, this protein forms the hearty base of the casserole.
- 3 medium zucchinis, thinly sliced: Adds freshness and a tender bite, plus beautiful color contrast.
- 1 small onion, diced: Provides a subtle sweetness and depth once sautéed.
- 2 cloves garlic, minced: Infuses a lovely aromatic punch that lifts all the other flavors.
- 1 cup shredded mozzarella cheese: Melts beautifully to give creamy, gooey goodness throughout.
- 1/2 cup grated Parmesan cheese: Brings a salty, nutty flavor that enhances the cheesy layers.
- 1 cup marinara sauce: Adds tangy tomato richness that ties everything together.
- 1 teaspoon dried Italian seasoning: A perfect herb blend that boosts herbal notes without overpowering.
- 1/2 teaspoon salt: Balances and intensifies the overall flavor profile.
- 1/4 teaspoon black pepper: Adds just enough warmth for subtle spice and complexity.
- 1 tablespoon olive oil: Used for sautéing and enhancing the richness of cooked aromatics.
- Fresh basil or parsley for garnish (optional): Adds freshness and a pop of color to the finished dish.
How to Make Savory Ground Turkey Zucchini Casserole Recipe
Step 1: Prepare Your Oven and Aromatics
Start by preheating your oven to 375°F (190°C) so it’s ready when your casserole is assembled. In a large skillet, warm the olive oil over medium heat. Toss in the diced onions and minced garlic, sautéing gently until they become translucent and fragrant, about three minutes. This foundational step builds layers of flavor right from the start.
Step 2: Cook the Ground Turkey
Add the ground turkey to the skillet, breaking it apart with a spatula as it cooks. Stir frequently until it’s browned thoroughly and no longer pink, which usually takes 6 to 8 minutes. Season the turkey with salt, black pepper, and the dried Italian seasoning to infuse every bite with well-rounded herbaceous notes.
Step 3: Combine with Marinara Sauce
Once your turkey is perfectly seasoned and cooked, stir in the marinara sauce. Let the mixture simmer for about two minutes to meld the flavors together. Then remove the skillet from heat to prepare for assembly, ensuring everything is warm and ready.
Step 4: Layer the Casserole
Grease a 9×13-inch baking dish lightly to prevent sticking. Place half of the thinly sliced zucchini in an even layer on the bottom. Next, spread half of the savory turkey mixture over the zucchini, followed by a generous sprinkle of half the mozzarella and Parmesan cheeses for gooey, cheesy layers.
Step 5: Repeat and Bake
Repeat the layering process with the remaining zucchini, turkey mixture, and cheeses. Then cover the dish with foil and bake for 30 minutes. After that, remove the foil and bake uncovered for an additional 10 minutes or until the cheese turns bubbly and golden brown—giving you that irresistible melty crust.
Step 6: Let It Rest and Garnish
Allow the casserole to cool for a few minutes before serving—this helps it set slightly for easier slicing. For a fresh touch, sprinkle chopped fresh basil or parsley on top if you like, bringing an inviting aroma and bright color to the plate.
How to Serve Savory Ground Turkey Zucchini Casserole Recipe

Garnishes
Fresh herbs like basil or parsley are wonderful garnishes that complement the savory turkey and zucchini perfectly. A light drizzle of extra virgin olive oil or a sprinkle of red pepper flakes can also add an exciting twist and elevate the dish visually and in flavor.
Side Dishes
This casserole pairs beautifully with simple sides like a crisp mixed green salad dressed with lemon vinaigrette or roasted garlic bread. You can also serve it alongside steamed rice or quinoa to soak up any lovely extra sauce.
Creative Ways to Present
For a fun presentation, try serving this casserole in individual ramekins instead of a large dish—perfect for entertaining or portion control. Alternatively, layer the casserole and then scoop out portions into bowls for a cozy, rustic meal that looks as inviting as it tastes.
Make Ahead and Storage
Storing Leftovers
Let any leftover Savory Ground Turkey Zucchini Casserole Recipe cool completely before transferring it to an airtight container. It will keep well in the refrigerator for up to 3 to 4 days, making it a convenient option for quick lunches or dinners during the week.
Freezing
You can freeze portions of the casserole before or after baking. Wrap individual servings tightly in plastic wrap and then foil, or store in freezer-safe containers. It will stay delicious in the freezer for up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat refrigerated or thawed casserole portions in the oven at 350°F (175°C) for about 15-20 minutes, or until warmed through. You can also microwave individual servings, but the oven method helps keep the texture more enjoyable, especially the cheesy top layer.
FAQs
Can I use ground chicken instead of ground turkey?
Absolutely! Ground chicken works just as well in this casserole and offers a similarly mild flavor and lean protein option.
Is it necessary to peel the zucchinis?
No need to peel them—the thin skin adds color and nutrients and becomes tender when baked, adding to the texture.
Can I make this casserole dairy-free?
Yes, you can substitute the mozzarella and Parmesan with your favorite dairy-free cheese alternatives or nutritional yeast for a cheesy flavor without dairy.
How spicy is this casserole?
This recipe is mild and family-friendly, but you can easily add crushed red pepper flakes to the turkey mixture or as a garnish if you prefer a bit of heat.
What if I don’t have marinara sauce on hand?
You can use any tomato-based pasta sauce you like or even make a quick sauce by simmering canned tomatoes with garlic and Italian herbs.
