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 the oven warms up, grab a 9×13-inch baking dish and lightly grease it with olive oil to prevent sticking and ensure a lovely crust on your Ground Turkey Zucchini Casserole.
Step 2: Sauté Onions and Garlic
In a large skillet over medium heat, add a tablespoon of olive oil. Toss in the chopped onion and minced garlic, sautéing for about 2 minutes until they become fragrant and the onion turns translucent. This aromatic base is essential for flavorful layers in your casserole.
Step 3: Brown the Turkey
Next, add the pound of ground turkey to the skillet, breaking it up with a spoon. Cook for 5-6 minutes or until it’s browned and fully cooked through. The turkey should no longer be pink; this is the groundwork for a hearty Ground Turkey Zucchini Casserole.
Step 4: Add Tomatoes and Seasoning
Once the turkey is browned, stir in the drained diced tomatoes, dried Italian herbs, salt, and black pepper. Let the mixture simmer for 3-4 minutes, allowing the flavors to meld together beautifully. You’ll know it’s ready when it’s bubbling gently and fragrant.
Step 5: Layer the Casserole
Start layering your casserole by placing half of the sliced zucchini at the bottom of the greased baking dish. Top with half of the ground turkey mixture, spreading it evenly, then sprinkle a generous layer of mozzarella cheese. Repeat these layers to build a delicious foundation for your Ground Turkey Zucchini Casserole.
Step 6: Bake to Perfection
Place the layered casserole in the preheated oven and bake uncovered for 30-35 minutes. Keep an eye on it; the casserole is done when it’s bubbly and the cheese has melted to a golden perfection, creating a mouthwatering topping.
Step 7: Cool and Serve
Once baked, remove the Ground Turkey Zucchini Casserole from the oven and let it cool for about 5 minutes. This resting time allows the flavors to settle and makes serving easier, enticing everyone with its aroma as you prepare to dish it out.

Helpful Tricks for Ground Turkey Zucchini Casserole
Perfect Layering: Always start with zucchini at the bottom; it releases moisture that keeps the casserole from drying out.
Cheese Options: Experiment with different cheeses like cheddar or provolone for unique flavors. Just ensure your chosen cheese melts well!
Avoid Watery Casserole: Drain the diced tomatoes thoroughly to prevent excess moisture, ensuring a hearty Ground Turkey Zucchini Casserole.
Fresh Herbs: Consider using fresh herbs instead of dried for an extra burst of flavor. Just remember to adjust the quantities!
Rest Before Serving: Allow the casserole to cool for a few minutes before cutting. This helps the layers set beautifully, making it easier to serve.
