Step‑by‑Step Instructions for Ground Turkey Casserole Recipe
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This step is crucial for ensuring your Low-Fat Ground Turkey Casserole bakes evenly while developing a beautiful, bubbly topping. While the oven heats up, gather your equipment—a large skillet and a baking dish, so you’re ready to go!
Step 2: Brown the Ground Turkey
In the large skillet, add the 1 pound of 99% lean ground turkey over medium heat. Use a spatula to break it apart as it cooks, allowing it to brown and reach an internal temperature of 165°F. This should take about 5-7 minutes. Once fully cooked, transfer the turkey to a plate and set aside.
Step 3: Sauté the Vegetables
In the same skillet, add your diced yellow onion, 1 cup of bell peppers, diced zucchini, and 2 cloves of minced garlic. Sauté over medium heat for about 5 minutes, stirring occasionally until the vegetables are tender and the onion becomes translucent. This step infuses your casserole with wonderful flavor!
Step 4: Season and Combine
Season the sautéed vegetables with salt, pepper, and 1½ teaspoons of Italian seasoning. Stir in the can of crushed tomatoes and ½ cup of fat-free chicken broth, combining everything well. Let the mixture simmer for about 5-7 minutes, allowing the flavors to meld together beautifully, creating a rich sauce for your ground turkey casserole.
Step 5: Assemble the Casserole
Pour the ground turkey mixture into a greased baking dish, spreading it out evenly. This ensures every bite of your Ground Turkey Casserole is packed with flavor. Top it off with ¼ cup of whole wheat breadcrumbs and ½ cup of part-skim mozzarella cheese for a delightful crunch and creamy finish.
Step 6: Bake to Perfection
Place the assembled casserole in the preheated oven and bake for 25-30 minutes. You’ll know it’s ready when the cheese is melted and bubbly, creating a savory golden crust. This is the moment where all the fragrant ingredients come together into one comforting dish.
Step 7: Cool and Serve
Once out of the oven, let the casserole cool for about 5-10 minutes before serving. This brief cooling time helps the casserole set, making it easier to portion and serve. Enjoy this hearty Low-Fat Ground Turkey Casserole as a satisfying meal, perfect for weeknight dinners or meal prep!

Make Ahead Options
This Low-Fat Ground Turkey Casserole is perfect for meal prep, allowing you to enjoy a hearty dish without the last-minute rush! You can prepare the casserole up to 24 hours in advance by cooking the ground turkey and sautéing the vegetables. Simply combine everything (including the crushed tomatoes and chicken broth), then transfer the mixture to a baking dish and sprinkle the breadcrumbs and cheese on top. Cover tightly with plastic wrap and refrigerate. When ready to enjoy, remove from the fridge, let it sit at room temperature for about 30 minutes, and bake as directed. This way, you’ll have a delicious, comforting meal ready to serve on your busiest nights!
