Ingredients You’ll Need
- 1 tablespoon olive oil: This helps sauté the zucchini and adds richness. You can substitute with avocado oil if preferred.
- 2 to 2½ pounds zucchini (about 3 to 4 medium): Provides a fresh, mild flavor and is the star of this dish. Choose firm zucchinis for the best texture.
- ¼ teaspoon salt: Enhances the flavors of the ingredients.
- ⅛ teaspoon black pepper: Adds a hint of spice, but feel free to adjust to your taste.
- 1 pound lean ground beef: The main source of protein which makes the casserole hearty. Alternatively, ground turkey or chicken can be used for a lighter option.
- 1 small yellow onion, finely diced: Brings sweetness and depth of flavor to the dish.
- 1 teaspoon Italian seasoning: A blend of herbs adding authenticity to the flavor profile. Dried herbs like oregano and basil can be used if you don’t have a premade mix.
- 1 teaspoon garlic powder: This adds a fragrant, savory undertone that pairs wonderfully with the meat.
- 1 (24-ounce) jar pasta sauce: Choose your favorite brand for convenience or make your own for a fresh taste.
- 1 (14.5-ounce) can petite diced tomatoes, gently drained: Incorporates texture and a bit of acidity. Consider using fire-roasted tomatoes for an added depth of flavor.
- 1 egg: Used to bind the cheese topping to create a delicious, creamy layer.
- 2 cups shredded Italian cheese blend: The gooey, melted cheese topping is a must for casserole satisfaction. You can substitute with shredded mozzarella or a dairy-free alternative as needed.
- ¼ cup milk: Adds creaminess to the cheese layer. Use any milk you have on hand, including non-dairy varieties.
How to Make Zucchini Hamburger Casserole
- Preheat the oven: Set your oven to 375°F (190°C). Grease a 9×13-inch baking dish and set it aside.
- Prepare the zucchini: Slice the zucchini in half lengthwise and then cut into ½-inch thick moons.
- Sauté the zucchini: Heat the olive oil in a large skillet over medium-high heat. Add the sliced zucchini, salt, and pepper. Sauté for about 3 to 6 minutes or until the zucchini begins to soften. Carefully transfer the sautéed zucchini to the prepared baking dish.
- Cook the beef: In the same skillet, add the lean ground beef and diced yellow onion. Cook over medium-high heat until the meat is browned and no pink remains, about 5 to 7 minutes. Drain any excess fat.
- Combine the filling: Stir in the Italian seasoning, garlic powder, pasta sauce, and gently drained diced tomatoes. Let the mixture simmer for a couple of minutes, then transfer it to the baking dish, mixing gently with the zucchini.
- Prepare the cheese topping: In a small bowl, whisk together the egg and milk. Add in the shredded Italian cheese blend, making sure the cheese is well coated in the egg mixture. Spoon the cheesy goodness evenly over the casserole.
- Bake the casserole: Place it in the oven and bake for 25 to 30 minutes or until the casserole is hot and bubbly and the cheese is melted and lightly browned.
- Let it rest: Before serving, let it rest for about 10 minutes. This allows the flavors to meld and the juices to thicken for a perfectly sliceable dish.
Storing & Reheating
Leftover Zucchini Hamburger Casserole can be stored at room temperature for up to 2 hours, then refrigerated for up to 4 days in an airtight container. If you would like to save it for a longer period, freeze it in a suitable container for up to 3 months. When you’re ready to enjoy again, reheat in the oven at 350°F (175°C) for about 20-25 minutes or until warmed through. Note that the zucchini may lose some texture when reheated, but a sprinkle of fresh cheese on top before reheating will rejuvenate its appeal.
Chef’s Helpful Tips
- Make sure to drain excess liquid from the zucchini to avoid a watery casserole.
- Brown the ground beef well to deepen the flavor—don’t rush this step!
- If you prefer a bit of spice, adding red pepper flakes enhances the flavor nicely.
- Consider mixing in some chopped spinach or bell peppers for added nutrition and flair.
- This dish can be prepared ahead of time; simply assemble it in the baking dish, cover, and store in the refrigerator until ready to bake.

How can I make this dish vegetarian?
To create a vegetarian version, simply omit the meat and replace it with additional vegetables or lentils for protein. Mushrooms, bell peppers, or even black beans work well and add heartiness to the dish without losing that comforting feel.
What side dishes pair well with Zucchini Hamburger Casserole?
This casserole is quite filling on its own, but you can serve it with a simple garden salad, garlic bread, or steamed vegetables for a well-rounded meal. Pairing with a light, fresh side helps balance the richness of the casserole.
Can I make this ahead of time?
Yes! You can prepare the entire casserole up to 24 hours in advance. Just cover it tightly and store it in the refrigerator. When you’re ready to bake, add a few extra minutes to the cooking time, as it will be cold from the fridge. Enjoy the convenience of having a homemade meal ready to go!
