Step‑by‑Step Instructions for Ground Turkey Zucchini Casserole
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This ensures the perfect baking environment for your Ground Turkey Zucchini Casserole. While the oven warms up, gather your ingredients and prepare your baking dish by greasing it lightly with cooking spray or oil.
Step 2: Cook the Ground Turkey
In a large skillet, heat a splash of olive oil over medium heat. Add the ground turkey and cook it for about 8-10 minutes, breaking it apart with a spatula as it browns. You’ll know it’s ready when the turkey is fully cooked with no pink remaining, releasing a savory aroma that fills the kitchen.
Step 3: Sauté Onions and Garlic
Once the turkey is cooked, add the diced onion and minced garlic to the skillet. Continue cooking for an additional 2 minutes, stirring occasionally, until the onions are translucent and fragrant. This mix will form a flavorful base for your Ground Turkey Zucchini Casserole.
Step 4: Add Zucchini
Next, stir in the chopped zucchini, cooking for 3-4 minutes until it softens slightly but still holds its shape. This step enhances the texture of the casserole while allowing the zucchini to absorb the flavors of the ground turkey and spices.
Step 5: Combine Remaining Ingredients
Incorporate the pre-cooked groats, drained diced tomatoes, oregano, and paprika into the skillet. Mix everything thoroughly, ensuring that the spices are evenly distributed. This will bring life to your Ground Turkey Zucchini Casserole while creating a colorful and hearty mixture.
Step 6: Transfer to Baking Dish
Pour the mixture into your greased 9×13 baking dish, spreading it out evenly. This step is crucial for ensuring that the casserole cooks uniformly. Once it’s well-distributed, sprinkle your shredded cheese generously on top to create a delicious, gooey finish.
Step 7: Bake the Casserole
Place the baking dish in the oven and let it bake uncovered for about 20-25 minutes. Watch for the cheese to become bubbly and golden brown—this indicates that the casserole is beautifully cooked through and ready to serve.
Step 8: Cool and Serve
After baking, remove the Ground Turkey Zucchini Casserole from the oven and allow it to cool for a few minutes. This brief cooling period will help the casserole set, making it easier to serve. Then, scoop out portions and enjoy your hearty and healthy dish!

Ground Turkey Zucchini Casserole Recipe FAQs
What type of zucchini should I use for the casserole?
It’s best to use fresh, firm zucchini that’s free from dark spots or soft spots. Look for medium-sized zucchini for the best flavor and texture. If you encounter larger zucchinis, they might have more seeds and be less flavorful, so it’s wise to choose those smaller ones!

What if my casserole turns out watery?
If you find that your casserole is watery, it’s usually due to insufficient drainage of the zucchini or using too many watery ingredients like fresh tomatoes.

Is this casserole suitable for pets or those with allergies?
While the Ground Turkey Zucchini Casserole is healthy for humans, it’s best to avoid feeding it to pets due to garlic and onions, which can be harmful to them.
