Ingredients Method

Ingredients
  

  • 500 g ground chicken or turkey
  • 1 egg
  • 2 tbsp almond flour
  • 2 garlic cloves
  • 1 tsp salt
  • ½ tsp black pepper
  • 1 tsp oregano
  • 1 cup tomato sauce
  • ½ cup Greek yogurt
  • 1 cup mozzarella
  • ¼ cup parmesan

Method
 

  1. Add the ground chicken or turkey into a large mixing bowl and gently break it apart using your hands or a spoon. Take your time here so the meat is evenly separated — this helps everything mix smoothly later without overworking the mixture.
  2. Add the egg, almond flour, minced garlic, salt, black pepper, and oregano directly into the bowl. Using your hands or a spatula, mix everything together gently until just combined. Stop as soon as the ingredients are evenly incorporated, because overmixing can make the meatballs dense and less tender.
  3. Scoop small portions of the mixture and roll them between your palms to form evenly sized meatballs. Try to keep them uniform in size so they cook evenly. Place each one onto a plate or tray as you go.
  4. If you want extra flavor, heat a skillet over medium heat and lightly sear the meatballs for a few minutes, turning them to brown on all sides. This step adds a deeper, richer taste, but you can skip it if you prefer a simpler method.
  5. In a separate bowl, add the tomato sauce and Greek yogurt. Whisk or stir until the mixture becomes smooth, creamy, and fully combined. This creates a rich, protein-boosted sauce that will keep the casserole moist.
  6. Lightly grease a baking dish and arrange the meatballs in a single layer. Leave a little space between each one so the heat can circulate properly during baking.
  7. Pour the prepared sauce evenly over the meatballs, making sure each one is well coated. Use a spoon or spatula if needed to spread the sauce into any gaps.
  8. Sprinkle the shredded mozzarella evenly across the top, followed by the grated parmesan. Make sure the cheese covers most of the surface so you get that golden, bubbly layer after baking.
  9. Place the dish into a preheated oven at 190°C (375°F) and bake for 25–30 minutes. The casserole is ready when the cheese is fully melted, slightly golden on top, and the meatballs are cooked through.
  10. Remove the dish from the oven and let it rest for about 5 minutes before serving. This resting time allows the casserole to set slightly, making it easier to serve while enhancing the overall texture and flavor.
