How to Make Ground Turkey Zucchini Casserole

Here’s Ground Turkey Zucchini Casserole in action—step by step, so you can bring it to the table fast. I designed it as a weeknight lifesaver because it’s hearty, protein-packed, and veggie-forward. I love how the cheese tops it all off without making it heavy. This guide keeps things simple, so you can focus on family conversations rather than long kitchen marathons.

Step 1: Preheat and prep

I preheat the oven to 375°F (190°C). Lightly oil a greased baking dish so the casserole lifts cleanly. This little step saves me from sticky edges when I slice later.

Step 2: Brown turkey with onion

In a skillet, I heat olive oil over medium heat. I add onion and cook until translucent and sweet. Then I crumble in the ground turkey and cook until browned.

Step 3: Add garlic and simmer sauce

I stir in garlic for about 30 seconds, just until fragrant. Next I pour in marinara sauce, Italian seasoning, paprika, salt, and pepper. I let it simmer for about 5 minutes to blend the flavors.

Step 4: Layer zucchini and turkey

In the baking dish, I arrange zucchini slices in an even layer. I spoon the turkey mixture over the zucchini, making sure each bite has some of both.

Step 5: Top with cheese and bake

Sprinkle mozzarella and Parmesan on top. I bake for 20–25 minutes until the cheese is bubbly and golden. I let it rest 5 minutes before serving so the slices set nicely.

Step 6: Rest and serve

Resting helps the cheese and sauces settle. Then I slice and serve the casserole while it’s still warm.

1. Preheat oven to 375°F (190°C). Lightly oil a greased baking dish.
2. In a skillet, heat olive oil over medium heat; add onion and cook until translucent.
3. Add ground turkey, breaking it up, and cook until browned. Stir in garlic for 30 seconds.
4. Stir in marinara, Italian seasoning, paprika, salt, and pepper; simmer about 5 minutes.
5. In the baking dish, arrange zucchini slices in an even layer. Spoon the turkey mixture over the zucchini.
6. Sprinkle mozzarella and Parmesan on top. Bake 20–25 minutes until bubbly and golden. Let rest 5 minutes before serving.

Tips for Success

I keep this dish light by choosing lean turkey and careful layering. Layer zucchini slices evenly so moisture and texture stay balanced. Resting time matters; a brief wait helps the cheese set for cleaner slices. For a lighter version, blend part-skim mozzarella and skip extra salt if your sauce is low-sodium. Let leftovers cool slightly before refrigerating to preserve moisture and texture.

• Lean turkey keeps it light
• Layer zucchini evenly for moisture
• Rest cheese briefly for clean slices
• Use part-skim mozzarella for lighter cheese
• Cool leftovers before refrigerating

Equipment Needed

Here’s the essential gear I reach for every time I make Ground Turkey Zucchini Casserole. The right equipment keeps prep smooth, edges clean, and the bake carefree, even on my busiest nights.

• Skillet for browning
• 9×13-inch greased baking dish
• Knife and cutting board
• Spatula and tongs
• Oven thermometer (optional, for accuracy)

With these tools, I move from chopping to bubbling cheese in minutes, making weeknights calmer, tastier, and a little more joyful.

Variations

• Swap ground turkey for ground chicken or turkey breast crumbles
• Add chopped mushrooms or spinach for extra greens
• Use low-sodium marinara and reduce salt
• Spice it up with red pepper flakes or a pinch of cayenne
• Try a three-cheese topping (mozzarella, Parmesan, and fontina)
