How to Make Ground Turkey Zucchini Casserole – Healthy Comfort Food
Step 1: Prepare Your Oven and Baking Dish
Begin by preheating your oven to 375°F (190°C). While it’s warming up, lightly grease a 9×13-inch baking dish with olive oil to ensure the casserole won’t stick and will brown evenly.
Step 2: Sauté Onions and Garlic
In a large skillet over medium heat, warm 1 tablespoon of olive oil. Add the chopped onion and minced garlic, cooking just until they become fragrant and translucent—about 2 minutes. This step creates a delicious aromatic foundation that draws you right into the kitchen.
Step 3: Cook the Ground Turkey
Next, add the ground turkey to the skillet with the onions and garlic. Break it up with a spoon and cook until browned all over, roughly 5 to 6 minutes, ensuring that every bite carries that rich meaty flavor.
Step 4: Add Tomatoes and Seasonings
Stir in the drained diced tomatoes along with dried Italian herbs, salt, and black pepper. Let this mixture simmer for 3 to 4 minutes so all the flavors meld together beautifully, creating a juicy and aromatic filling.
Step 5: Layer Your Casserole
Now for the fun part—layering! Place half of the sliced zucchinis evenly on the bottom of your prepared baking dish. Spoon half of the turkey mixture over the zucchini, and sprinkle with half of the shredded mozzarella cheese. Repeat with another layer of zucchini, turkey, and cheese to create a casserole that’s as beautiful as it is tasty.
Step 6: Bake Until Golden and Bubbly
Bake your Ground Turkey Zucchini Casserole – Healthy Comfort Food uncovered for 30 to 35 minutes. You’ll know it’s done when the cheese is melted and golden, and the dish is bubbly around the edges. Let it rest for about 5 minutes before serving to let everything set perfectly.
How to Serve Ground Turkey Zucchini Casserole – Healthy Comfort Food

Garnishes
A sprinkle of fresh chopped parsley or basil instantly brightens the casserole and adds a pop of color. A light drizzle of extra virgin olive oil or a few red pepper flakes can also elevate the flavor for those who like a touch of heat.
Side Dishes
This casserole pairs wonderfully with a crisp green salad dressed in a lemon vinaigrette or a side of roasted sweet potatoes. Both bring complementary flavors and textures without overshadowing the star of the meal.
Creative Ways to Present
For an appealing presentation, try serving this casserole straight from individual ramekins for a cozy, personal touch. Alternatively, layering in clear glass dishes lets the vibrant greens and reds shine through, tempting everyone to dig in.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover any leftovers in an airtight container and store them in the refrigerator for up to 3 days. This meal tastes great reheated, and the flavors actually deepen after resting.
Freezing
You can freeze portions of the casserole for up to 2 months. Just make sure to wrap it tightly with foil and plastic wrap or place it in a freezer-safe container. When you’re ready for a cozy meal, thaw it overnight in the fridge.
Reheating
Reheat leftovers in the oven at 350°F (175°C) for about 15-20 minutes until warmed through and the cheese is bubbly again. You can also microwave individual servings, but for the best texture, the oven is preferred.
FAQs
Can I use ground chicken instead of ground turkey?
Absolutely! Ground chicken is a great substitute and will keep the casserole lean and delicious. Just be sure to cook it thoroughly, as you would the turkey.
Is it okay to use zucchini without draining it?
Draining the tomatoes is important to avoid excess moisture, but slicing zucchini without salting or draining is fine since it bakes in the casserole and holds its structure well.
Can I add other vegetables to this casserole?
Definitely! Feel free to throw in some diced bell peppers, mushrooms, or spinach to pack in more nutrients and texture variation.
What can I use instead of mozzarella cheese?
Cheeses like provolone, cheddar, or even a sprinkle of Parmesan can work well if you want a different twist or need to use what you have on hand.
Is this casserole suitable for meal prepping?
Yes, it’s perfect for meal prepping because it stores well and reheats beautifully, making for healthy, satisfying meals throughout the week.
