Equipment 🥘
Before we get cooking, let’s gather everything you need to streamline the process! Here’s your essential kitchen toolkit:
- Mixing bowls (for meatball mixture)
- Measuring cups and spoons
- Strainer (for zucchini)
- Baking dish or casserole pan
- Baking sheet (if needed for cooking without a dish)
- Oven mitts (safety first!)
- Spatula or wooden spoon (for mixing)
- Grater (for zucchini and cheeses)

Step-by-Step Recipe Instructions
Yields: 6 servings
- Prep Your Ingredients: Start by preheating your oven to 400°F (200°C). While that’s warming up, take your zucchini, wash it well, and using a grater, shred it into fine pieces. Now, grab a strainer or a clean dish towel, and press the zucchini to remove as much moisture as possible. This ensures that your casserole won’t be too watery!
- Make the Meatball Mixture: In a large mixing bowl, combine the ground turkey and Italian sausage. Add in the three stars of flavor—mozzarella cheese, parmesan cheese, and the strained zucchini—along with your egg, onion powder, garlic powder, and dried basil. Season generously with salt and pepper. Mix everything together gently using your hands or a spatula until just combined. Remember, overmixing can make the meatballs tough, so be gentle!
- Shape the Meatballs: Now comes the fun part—rolling the mixture into meatballs! Scoop out portions of the mixture, about the size of a golf ball, and roll them gently between your palms. Place them evenly spaced in the chosen baking dish. This method will help each meatball cook evenly, and trust me, they’re going to be delish!
- Bake the Meatballs: Slide the dish into your preheated oven and bake for 25-30 minutes, or until the meatballs are cooked through. If you notice any excess moisture pooling in the bottom of the dish halfway through cooking, don’t hesitate to drain it off to keep the casserole from becoming soggy.
- Add the Kale and Toppings: Once the meatballs are almost cooked, it’s time to color your dish! Take your chopped kale and spread it around the meatballs, creating a vibrant green layer. Then, generously pour the low-carb tomato sauce over the meatballs and finally sprinkle the remaining mozzarella cheese on top.
- Final Baking: Place the casserole back in the oven and bake for an additional 10-12 minutes, or until the cheese is perfectly melted and bubbling. If you want that gorgeous golden-brown cheese crust, feel free to broil it for 2-3 minutes at the end, just keep an eye on it!
- Serve and Enjoy: Once done, remove the casserole from the oven (using those trusty oven mitts!), let it cool for a few minutes, and then serve warm! This dish shines on its own, but feel free to pair it with a fresh salad or a glass of sparkling water.
