This ground turkey zucchini casserole is a fantastic choice when you want a wholesome and comforting dinner that comes together quickly. It balances lean protein, fresh veggies, and gooey mozzarella in a way that feels both satisfying and light on the stomach. It has become my go-to on busy weeknights when I want something hearty without the fuss.

I put this casserole together after cleaning out the fridge and it quickly became a family favorite. The combination of flavors is easy to customize too which keeps it fresh week after week.

Ingredients

  • One pound of ground turkey: provides lean protein that cooks quickly and soaks up flavors well
  • Two medium zucchinis sliced: add moisture, texture, and a mild sweetness that balances the turkey
  • One cup of shredded mozzarella cheese: melts beautifully and gives a creamy texture to the casserole
  • Half a cup of chopped onion: builds a flavorful base with a slight sweetness when sautéed
  • Two cloves of garlic minced: add depth and warmth, crucial for layering flavors
  • One 14-ounce can of diced tomatoes drained: brings acidity and moisture without making the casserole too wet
  • One teaspoon of dried Italian herbs: blends classic Mediterranean flavors like oregano and basil
  • Half a teaspoon of salt: enhances all the ingredients naturally
  • Quarter teaspoon of black pepper: adds just enough bite to keep it interesting
  • One tablespoon of olive oil for sautéing: adds richness and helps season the vegetables

Instructions

Build The Base:
Preheat your oven to 375 degrees Fahrenheit. Use some olive oil to grease a 9 by 13-inch baking dish so the casserole won&t stick after baking.
Sauté Aromatics:
Heat olive oil in a large skillet over medium heat. Cook the chopped onion and minced garlic for about two minutes until soft and fragrant. This step is key to developing flavor that will soak into the turkey as it cooks.
Brown The Turkey:
Add the ground turkey to the skillet. Break it apart with a spoon and cook for five to six minutes until it is nicely browned and no longer pink. Browning gives the dish more richness and texture.
Simmer With Tomatoes and Herbs:
Stir in the drained diced tomatoes, dried Italian herbs, salt, and black pepper. Let this simmer gently for three to four minutes so the flavors meld and the tomatoes soften.
Layer The Casserole:
Place half of the sliced zucchini evenly in the greased baking dish. Layer half of the cooked turkey mixture on top followed by half of the shredded mozzarella cheese. Repeat these layers ending with cheese on top.
Bake And Rest:
Bake uncovered for thirty to thirty-five minutes until the casserole is bubbly and the mozzarella has melted into a golden crust. Let it cool five minutes before cutting to help the layers set.

What I love most about this casserole is how the mozzarella cheese unites the layers with a comforting cheesiness making it feel indulgent but it is actually quite light. It always brings back memories of cozy family dinners where everyone was eager for seconds.

Storage tips

Cool leftovers completely before storing them in an airtight container. The casserole keeps well in the fridge for up to three days and can be reheated in the oven or microwave. You can also freeze portions for up to two months; thaw overnight before reheating.

Ingredient swaps

Ground chicken or lean beef work well in place of turkey if you prefer a different meat flavor. Try swapping mozzarella for feta or goat cheese for a tangy twist. Zucchini can be replaced with yellow squash or thinly sliced eggplant depending on what is in season.

Serving ideas

Pair this casserole with a simple green salad dressed with lemon vinaigrette for freshness. Crusty bread or garlic bread on the side makes it feel more indulgent. A dollop of plain Greek yogurt on top adds creaminess and tang.
