This Ground Turkey Zucchini Casserole is a wholesome, comforting dish perfect for weeknight dinners when you want something healthy but satisfying. It combines lean ground turkey with fresh zucchini and melty mozzarella for a low-carb meal that feels like a treat without the heaviness of traditional casseroles.

I first made this recipe when looking for a lighter alternative to cheesy pasta bakes. Now it’s one of my go-to dinners whenever I want something hearty yet healthy. The blend of juicy tomatoes and melted cheese always wins over even picky eaters.

Ingredients

  • One pound ground turkey: perfect for a lean source of protein with mild flavor
  • Two medium zucchinis sliced: fresh for a tender-crunchy texture and moisture
  • One cup shredded mozzarella cheese: to add gooey, melty richness that pulls everything together
  • Half cup chopped onion: which softens and sweetens to build flavor layers
  • Two cloves garlic minced: to give that savory aromatic punch
  • One 14-ounce can diced tomatoes: drained carefully to avoid excess water that can make the casserole watery
  • One teaspoon dried Italian herbs: for balanced earthiness and herbaceous notes
  • Half teaspoon salt: to season and enhance all the flavors
  • Quarter teaspoon black pepper: for subtle heat and depth
  • One tablespoon olive oil: to sauté aromatics and prevent sticking

Step-by-Step Instructions

Preheat the Oven:
Set your oven to 375 degrees Fahrenheit or 190 degrees Celsius. Lightly grease a 9 by 13 inch baking dish with olive oil so nothing sticks when baking.
Sauté Aromatics:
Warm olive oil over medium heat in a large skillet. Add diced onion and minced garlic and cook, stirring often for about two minutes. You want them soft and fragrant but not browned to develop a mellow sweet flavor base.
Cook Ground Turkey:
Add ground turkey to the skillet. Use a spoon to break apart the meat. Cook for five to six minutes until the turkey is browned and fully cooked through with no pink remaining.
Simmer with Tomatoes and Herbs:
Mix in the drained diced tomatoes, dried Italian herbs, salt, and black pepper to the turkey. Let everything simmer for three to four minutes. This step helps deepen the flavor and meld the ingredients.
Layer the Casserole:
In the prepared baking dish, arrange half of the zucchini slices in an even layer. Spread half of the turkey mixture on top, then sprinkle half the mozzarella cheese over everything. Repeat these layers with the remaining zucchini, turkey, and cheese until all ingredients are used.
Bake:
Put the casserole uncovered in the oven. Bake for thirty to thirty five minutes until you see bubbling around the edges and the cheese is beautifully golden brown on top.
Cool and Serve:
Take the casserole out of the oven and let it rest five minutes. This helps the dish set so it slices better and isn’t too runny on the plate.

I love the way the mozzarella melts into the zucchini and turkey creating a comforting texture that feels both hearty and fresh. This recipe became a family favorite during cold months when we crave something nourishing but easy to prepare.

Storage Tips

Store leftovers in an airtight container in the refrigerator. They stay fresh up to three days. Reheat gently in the oven or microwave to keep the cheese creamy and the vegetables tender without drying out.

Ingredient Substitutions

If you cannot find ground turkey, ground chicken or lean ground beef can be used as alternatives. For a dairy-free version, swap mozzarella with dairy-free cheese or omit it and add nutritional yeast for flavor.

Serving Suggestions

Serve this casserole with a crisp green salad or some roasted vegetables on the side to complete the meal. A sprinkle of fresh parsley or basil on top brightens the flavors just before serving.
