Tools & Equipment Needed

  • 9×13-inch baking dish
  • Large skillet
  • Cutting board
  • Sharp knife
  • Wooden spoon or spatula
  • Measuring spoons
  • Oven mitts

Optional helpful tools:

  • Mandoline slicer for uniform zucchini slices
  • Cheese grater (if shredding fresh mozzarella)

Step-by-Step Instructions

1. Preheat and Prepare Dish

Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish with olive oil to prevent sticking and ensure even cooking.

2. Sauté Onions and Garlic

In a large skillet over medium heat, add olive oil. Add the chopped onion and minced garlic and sauté for about 2 minutes, until fragrant and softened. The onion should become translucent but not browned.

3. Cook Ground Turkey

Add 1 lb ground turkey to the skillet. Cook for 5–6 minutes, breaking it up with a spoon as it browns. The turkey should be fully cooked with no pink remaining.

4. Add Tomatoes and Seasonings

Stir in the drained 14 oz diced tomatoes, 1 tsp dried Italian herbs, 1/2 tsp salt, and 1/4 tsp black pepper. Allow the mixture to simmer gently for 3–4 minutes so the flavors combine and excess moisture reduces slightly.

5. Layer the Casserole

Place half of the sliced zucchini in the prepared baking dish, arranging evenly.
Top with half of the turkey mixture.
Sprinkle half of the shredded mozzarella cheese over the top.
Repeat with remaining zucchini, turkey mixture, and cheese.

6. Bake Until Golden

Bake uncovered for 30–35 minutes, until bubbly and the cheese is melted and golden brown.
Let cool for 5 minutes before serving to allow the layers to set.

Serve warm and enjoy.

Tips & Variations

  • Vegetarian Option: Replace ground turkey with a plant-based ground alternative while keeping all other measurements identical.
  • Gluten-Free: This recipe is naturally gluten-free as written.
  • Dairy-Free: Replace mozzarella with a dairy-free cheese alternative.
  • Spice Adjustment: Add crushed red pepper flakes to the turkey mixture for gentle heat.
  • Pantry Swap: Ground chicken or lean beef can replace turkey in equal quantity.
  • Seasonal Variation: Add fresh basil or parsley as garnish for brightness.

Flavor Profile

This Ground Turkey Zucchini Casserole is savory, slightly herbaceous, and lightly tangy from the tomatoes. The zucchini becomes tender but still structured, absorbing juices from the turkey mixture. Mozzarella adds creaminess and mild richness without overpowering. As it bakes, the herbs bloom and deepen, and the cheese forms a lightly golden top that contrasts beautifully with the juicy interior.

The mouthfeel is balanced — tender vegetables, crumbly yet moist turkey, and stretchy melted cheese all in one forkful.
