Step‑by‑Step Instructions for Ground Turkey Zucchini Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While it warms, take a moment to grease a 9×13-inch baking dish with olive oil, ensuring a non-stick surface for your delicious Ground Turkey Zucchini Casserole. This step is essential for easy serving and cleanup later on.
Step 2: Sauté Aromatics
In a large skillet, heat a tablespoon of olive oil over medium heat. Add the chopped onion and minced garlic, cooking for about 2 minutes until they become fragrant and soft. This fragrant mixture will lay the groundwork for the comforting flavors in the casserole, bringing out the richness of the ground turkey.
Step 3: Brown the Turkey
Add the ground turkey to the skillet, breaking it up with a spatula. Cook for about 5-6 minutes, stirring occasionally, until it’s browned and no longer pink. This browning not only develops flavor but also ensures the turkey is fully cooked, preparing it to nestle beautifully with the other ingredients in your casserole.
Step 4: Mix in Tomatoes and Seasoning
To the skillet, stir in the drained diced tomatoes along with the dried Italian herbs, salt, and black pepper. Let this mixture simmer for 3-4 minutes, allowing the flavors to meld together. You’ll notice the aromas rising, hinting at the comforting taste that will soon fill your kitchen with warmth.
Step 5: Layer the Casserole
In your prepared baking dish, layer half of the zucchini slices, followed by half of the turkey mixture. Sprinkle on half of the shredded mozzarella cheese to enhance creaminess. Repeat the layering process with the remaining zucchini, turkey mixture, and finish with the last of the cheese, creating a delightful and colorful construction.
Step 6: Bake to Perfection
Place your assembled casserole in the preheated oven, uncovered, and bake for 30-35 minutes. Look for the cheese to be bubbly and golden on top, signaling that your Ground Turkey Zucchini Casserole is cooking beautifully. The enticing smells wafting through your home will be hard to resist!
Step 7: Cool and Serve
Once baked, remove the casserole from the oven and allow it to cool for about 5 minutes before serving. This brief resting time helps it set, making it easier to cut and serve. Enjoy your delicious casserole as a nourishing meal, perfect for family gatherings or cozy weeknights!

Ground Turkey Zucchini Casserole Recipe FAQs
What kind of zucchini should I use for this casserole?

You’ll want to store leftovers in an airtight container in the refrigerator. They’ll stay fresh and tasty for up to 3 days. Simply reheat in the oven or microwave when you’re ready for another delicious meal!

What if I want to use frozen zucchini instead?
If you decide to use frozen zucchini, make sure it’s thoroughly drained and pat it dry with a paper towel to avoid a watery casserole. I recommend sautéing the frozen zucchini for a few minutes before layering it in the casserole to help release moisture and keep the texture intact.

Very! This Ground Turkey Zucchini Casserole is naturally low-carb and gluten-free.
