How to Make Ground Turkey Zucchini Casserole – Healthy Comfort Food
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with a bit of olive oil so your casserole doesn’t stick and gets a nice golden finish.
Step 2: Sauté Onion and Garlic
In a large skillet over medium heat, warm the olive oil and sauté the chopped onion and minced garlic for about 2 minutes until they become fragrant and soft—this is where your flavor foundation begins to build!
Step 3: Brown the Ground Turkey
Add the ground turkey to the skillet and cook it thoroughly, breaking it up with your spoon as it browns, usually around 5 to 6 minutes. This step ensures every bite is packed with that satisfying turkey goodness.
Step 4: Simmer with Tomatoes and Spices
Stir in the drained diced tomatoes, dried Italian herbs, salt, and black pepper. Allow it all to simmer gently for 3 to 4 minutes so the flavors meld into a savory, juicy filling.
Step 5: Assemble the Layers
Now comes the fun part—layering your casserole! Start by placing half of the sliced zucchini in the bottom of your prepared dish. Next, spread half of the delicious turkey mixture on top, followed by a sprinkle of half the mozzarella cheese. Repeat this process to create two lovely layered stacks.
Step 6: Bake to Perfection
Bake uncovered for 30 to 35 minutes, until the casserole is bubbly, and the cheese is melted to a golden finish. Let it cool for about 5 minutes before serving—that way all those amazing flavors settle into a perfect harmony.
How to Serve Ground Turkey Zucchini Casserole – Healthy Comfort Food

Garnishes
Nothing elevates a casserole quite like a vibrant garnish. Sprinkle fresh chopped basil or parsley on top just before serving to introduce a burst of color and fresh herbal aroma. A light drizzle of extra virgin olive oil or a pinch of red chili flakes can also brighten the dish and add layers of flavor.
Side Dishes
This casserole shines as the star of the meal but pairs wonderfully with a crisp side salad for a refreshing contrast, or a warm crusty bread to soak up all those delicious juices. Roasted garlic green beans or steamed broccoli also complement the protein and veggies beautifully, rounding the meal out without overpowering the main dish.
Creative Ways to Present
For a family-style meal, serve the casserole right from the baking dish, letting everyone help themselves to generous portions. For a more elegant presentation, use individual ramekins or small ceramic dishes to bake and serve single portions. You can also jazz it up by topping each serving with a sunny-side-up egg for a flair of indulgent richness.
Make Ahead and Storage
Storing Leftovers
Ground Turkey Zucchini Casserole – Healthy Comfort Food keeps well in the fridge for up to 3 days. Simply cover your casserole with foil or transfer any leftovers to an airtight container to maintain freshness and moisture.
Freezing
If you want to keep this dish on hand for quick meals during busy weeks, it freezes beautifully. After baking and cooling, wrap tightly with plastic wrap and then aluminum foil or place in a freezer-safe container. It will stay delicious for up to 3 months.
Reheating
To reheat, thaw the casserole in the fridge overnight if frozen. Warm it in the oven at 350°F (175°C) for 15-20 minutes until heated through and bubbly again. You can also microwave individual portions for convenience, but the oven method helps keep the cheese melty and golden.
