Zucchini: They provide moisture and structure to the casserole. If you don’t have zucchini on hand, other vegetables like bell peppers or squash can be used instead.

How to Prepare the Ground Turkey Zucchini Casserole Step by Step
Follow these step-by-step instructions to make your casserole perfectly:
-
Preheat the Oven: Preheat your oven to 375°F (190°C). Preheating ensures an even cooking temperature for your casserole.
- Pro Tip: Use an oven thermometer to check that your oven reaches the correct temperature for the best results.
-
Grease the Baking Dish: Grease a 9×13-inch baking dish with olive oil. This helps to prevent sticking and makes cleanup easier.
- Pro Tip: You can also use non-stick spray instead of olive oil for a quicker application.
-
Sauté Onions and Garlic: In a large skillet over medium heat, add olive oil. Sauté the chopped onion and minced garlic for about 2 minutes until fragrant and the onion is translucent.
- Pro Tip: Sautéing the onion and garlic enhances their flavors, adding a deeper taste to the casserole.
-
Brown the Ground Turkey: Add the ground turkey to the skillet and cook for about 5-6 minutes, breaking it up with a spoon until browned.
- Pro Tip: Don’t overcrowd the skillet; this ensures even cooking. If necessary, cook in batches.
-
Add the Diced Tomatoes and Seasonings: Stir in the drained diced tomatoes, Italian herbs, salt, and black pepper. Let it simmer for about 3-4 minutes.
- Pro Tip: Tasting the mixture and adjusting the seasoning is key! Feel free to add more herbs if you love flavor.
-
Layer the Ingredients: In the prepared baking dish, layer half of the sliced zucchini, top with half of the turkey mixture, and sprinkle with half of the mozzarella cheese. Repeat the layers.
- Pro Tip: Pressing down the layers slightly can help the casserole cook evenly.
-
Bake the Casserole: Bake uncovered for 30-35 minutes, or until the casserole is bubbly and the cheese is golden.
- Pro Tip: If the cheese starts browning too quickly, cover the dish loosely with foil.
-
Cool and Serve: Allow the casserole to cool for about 5 minutes before serving. This lets the layers set a little and makes serving easier.
- Pro Tip: Garnish with fresh herbs like basil or parsley for a pop of color and freshness.
