Step‑by‑Step Instructions for Ground Turkey Zucchini Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While your oven heats up, grab a 9×13-inch baking dish and spray it generously with non-stick cooking spray to prevent sticking. This step is crucial, as it will ensure your delicious Ground Turkey Zucchini Casserole slides out easily once it’s baked.
Step 2: Sauté Aromatics
In a large skillet, heat a tablespoon of olive oil over medium heat. Once shimmering, add diced onion and minced garlic, sautéing them for about 3–4 minutes until they become translucent and fragrant. This aromatic base is key to infusing the casserole with savory flavors that will elevate your dish.
Step 3: Brown the Turkey
Add the ground turkey to the skillet, using a spoon to break it apart as it cooks. Incorporate Italian seasoning, salt, and pepper, and allow it to brown for approximately 5–7 minutes until fully cooked, and no pink remains. This step creates a hearty base for your casserole, combining the turkey with delicious, aromatic notes.
Step 4: Incorporate Vegetables
Next, stir in the sliced zucchini and drained diced tomatoes. Cook this mixture for about 5 minutes, or until the zucchini starts to soften and brightens in color. This will not only add moisture to the Ground Turkey Zucchini Casserole but will also contribute a delightful texture to every bite.
Step 5: Add Cheese
Remove the skillet from heat and mix in half of the shredded cheese, stirring until it’s melted and well combined. This cheesy addition binds the ingredients together, making each portion creamy and satisfying as you prepare to assemble your casserole.
Step 6: Assemble the Casserole
Spread the turkey and zucchini mixture evenly into the prepared baking dish, ensuring it’s distributed evenly. This layer will serve as the hearty foundation of your Ground Turkey Zucchini Casserole, making it a beautiful centerpiece for your table.
Step 7: Top with Cheese and Crust
Sprinkle the remaining cheese on top of the casserole, followed by freshly grated Parmesan cheese and optional breadcrumbs if desired. This layer will melt and create a bubble of golden goodness while baking, giving your casserole that irresistible crispy topping.
Step 8: Bake to Perfection
Place your casserole in the preheated oven and bake for 20–25 minutes. Keep an eye on it until the cheese is bubbly and golden brown, creating a mouthwatering visual that’ll have everyone eager for a taste of your scrumptious Ground Turkey Zucchini Casserole.
Step 9: Cool and Serve
Once out of the oven, allow the casserole to cool for a few minutes before cutting. This cooling time is essential for easier serving and cuts, ensuring that your beautiful layers hold their shape while you dish it out. Enjoy the comfort of this wholesome casserole with your loved ones!
