Ingredients
- 1 lb ground turkey
- 2 medium zucchinis, sliced
- 1/2 cup chopped onion
- 2 cloves garlic, minced
- 1 can (14 oz) diced tomatoes, drained
- 1 cup shredded mozzarella cheese
- 1 tsp dried Italian herbs
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1 tbsp olive oil
Instructions
- Step 1: 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.
- Step 2: In a large skillet over medium heat, add olive oil and sauté the chopped onion and minced garlic until fragrant and softened, about 2 minutes.
- Step 3: Add the ground turkey to the skillet and cook until browned, breaking it up with a spoon for even cooking, about 5-6 minutes.
- Step 4: Stir in the drained diced tomatoes, dried Italian herbs, salt, and black pepper. Let the mixture simmer gently for 3-4 minutes to combine the flavors.
- Step 5: Place half of the sliced zucchini in the prepared baking dish as the first layer. Top with half of the turkey mixture, then half of the shredded mozzarella cheese.
- Step 6: Repeat the layers with the remaining zucchini, turkey mixture, and cheese.
- Step 7: Bake the casserole uncovered for 30-35 minutes, until bubbly and cheese is golden brown. Let it cool for 5 minutes before serving.
