Who’s the best at making delicious, vegetarian casserole recipes? My mom! She was the first who made this awesome, healthy zucchini moussaka and I absolutely loved it! I’m glad I learned this recipe from her. This vegetarian moussaka recipe is low calorie, low fat and 100% tasty! Also, the prep part is really quick so you won’t spend a lot of time in the kitchen.

The original recipe contains eggs but it can easily be veganized if you use egg substitutes. I actually tried it with psyllium husks instead of eggs and it was perfect! You should try this vegetarian zucchini recipe!

  1. Moussaka is one of my favorite recipes and it reminds me of my childhood. Your recipe is so delicious, Ruxandra! Will definitely do it again soon. Can I replace the button mushrooms with Pleurotus mushrooms?
