- Gather the ingredients and preheat the oven to 350°F (180°C). 
- Heat half the extra virgin olive oil in a wide pan and fry the eggplant slices for 1-2 minutes on each side until golden brown. 
- Arrange the eggplant slices in an ovenproof dish—season with salt, pepper, and oregano. 
- In the same frying pan heat the remaining olive oil and sauté the ground beef with the onion, stirring for 5-7 minutes—season with paprika, salt, and pepper. Add the tomato puree and simmer for 4-5 minutes. 
- Pour the ground meat mixture on top of the eggplant slices. 
- Whisk the eggs and mix with Greek yogurt—season with salt and pepper.   
- Pour over the ground meat and spread evenly with a spatula or the back of a spoon. Sprinkle with parmesan cheese and bake for 30 minutes, covering with foil if needed to protect the sauce from burning.  
- Let the Moussaka rest for 5-10 minutes before slicing and serving hot.
