If you like skillet dinners with minimal cleanup, you might also enjoy the hearty flavors in our ground turkey zucchini skillet which shares many of the same comforts.

Why This Recipe Is a Great Choice

This recipe balances speed and satisfaction, giving you a nutritious dinner that still feels indulgent. The lean turkey keeps the dish light while the zucchini provides moisture and a subtle crunch when not overcooked. Using canned diced tomatoes adds acidity and a touch of sweetness without extra prep. A mix of cheddar or mozzarella with a sprinkle of Parmesan creates a melty center and a savory browned top. Breadcrumbs are optional but add a lovely toasted texture that contrasts the creamy interior. It is an adaptable recipe that welcomes extra herbs or veggies if you want to customize it for the family.

Flavor and Texture

The flavor rides on Italian seasoning, garlic, and the sweet tang of drained diced tomatoes, which cut through the richness of the cheese. Ground turkey offers a mild base that picks up every seasoning, letting the zucchini and tomatoes shine. The contrast between the soft, saucy middle and the crisp, cheesy top keeps each bite interesting. Parmesan brings a nutty, salty note that makes the casserole feel restaurant worthy. Overall, it hits a comforting balance of savory, bright, and cheesy textures that adults and kids both enjoy.

Ingredients

1 lb ground turkey
2 medium zucchinis, sliced
1 small onion, diced
2 cloves garlic, minced
1 can (14.5 oz) diced tomatoes, drained
1 cup shredded cheese (cheddar or mozzarella work well)
1 tsp Italian seasoning
Salt and pepper to taste
1 tbsp olive oil
1/4 cup grated Parmesan cheese
1/4 cup breadcrumbs (optional for topping)
Non-stick cooking spray

Step by Step Instructions

Preheat your oven to 375°F (190°C). Lightly spray a 9×13-inch baking dish with non-stick cooking spray and set aside.
In a large skillet, heat the olive oil over medium heat. Add the diced onion and minced garlic, sautéing until the onion becomes translucent.
Add the ground turkey to the skillet. Cook until browned, breaking it apart with a spoon. Season with Italian seasoning, salt, and pepper.
Stir in the sliced zucchinis and drained diced tomatoes. Cook for an additional 5 minutes until the zucchini starts to soften.
Remove the skillet from heat and mix in half of the shredded cheese, stirring to combine.
Transfer the turkey and zucchini mixture into the prepared baking dish, spreading it evenly.
Top with the remaining shredded cheese, Parmesan cheese, and breadcrumbs, if using.
Bake in the preheated oven for 20-25 minutes, or until the cheese is bubbling and the top is golden brown.
Remove from the oven and allow the casserole to cool for a few minutes before serving.

Tips for Best Results

Choose zucchinis that are firm and medium sized to avoid excess water in the pan. If your zucchinis seem watery, salt them lightly, let them sit for 10 minutes, then pat dry before cooking. Use freshly grated Parmesan for the best flavor and a more even melt under the broiler. If you want extra richness, stir a splash of milk into the shredded cheese before topping.

Storage and Make Ahead

Cool the casserole completely before covering and refrigerating to keep it fresh. Stored in an airtight container, it will keep well for up to three days and reheats nicely in the oven or microwave. To make ahead, prepare through step six, cover, and refrigerate; add toppings and bake when ready. For longer storage, portions freeze well for up to two months; thaw overnight in the refrigerator before reheating.
