Step‑by‑Step Instructions for Ground Turkey Zucchini Casserole
Step 1: Preheat and Prepare
Set your oven to preheat at 375°F (190°C) while you grease a 9×13-inch baking dish with a splash of olive oil. This step is crucial to ensure a non-stick surface for your Ground Turkey Zucchini Casserole, allowing for easy serving once it’s baked. A nice layer of oil will also enhance the casserole’s flavor and texture.
Step 2: Sauté Aromatics
In a large skillet over medium heat, pour in a tablespoon of olive oil and add the chopped onion and minced garlic. Sauté them for about 2 minutes, stirring frequently until fragrant and the onions become translucent. This aromatic base will infuse your casserole with rich flavors that complement the turkey beautifully.
Step 3: Brown the Ground Turkey
Add the ground turkey to the skillet, breaking it apart with a wooden spoon. Cook for 5-6 minutes, stirring occasionally until the turkey is browned and no longer pink. This browning step is essential for developing savory flavor in your Ground Turkey Zucchini Casserole, ensuring that the meat foundation is both delicious and safe to eat.
Step 4: Add Seasonings and Tomatoes
Stir in the drained diced tomatoes, dried Italian herbs, salt, and black pepper to the skillet, mixing well. Allow this mixture to simmer for 3-4 minutes on low heat. The tomatoes will add moisture, and the herbs will uplift the taste, creating a robust filling for your casserole.
Step 5: Layer the Casserole
In the greased baking dish, layer half of the zucchini slices along the bottom, creating an even base. Next, add half of the turkey mixture and sprinkle with half of the shredded mozzarella cheese. Repeat this layering with the remaining zucchini, turkey, and cheese to build a hearty Ground Turkey Zucchini Casserole that’s full of flavor and texture.
Step 6: Bake to Perfection
Place the casserole in the preheated oven and bake it uncovered for 30-35 minutes, or until the cheese is bubbly and golden brown on top. This baking time allows all the flavors to meld beautifully, while the zucchini becomes tender yet still maintains some structure for a delicious bite.
Step 7: Cool and Serve
Once baked, remove your Ground Turkey Zucchini Casserole from the oven and let it sit for about 5 minutes. This brief cooling period helps set the layers, making it easier to slice and serve. The result will be a comforting, hearty dish that your family will love at the dinner table.
