A comforting vegetarian zucchini moussaka layered with a savory mushroom-and-tomato filling and baked until golden. Best served with a dollop of sour cream on top.
Heat the olive oil in a large pan. Add the chopped onion and saute for 2-3 minutes. Add the chopped mushrooms and saute for another 5 minutes. Stir in 1 cup of chopped, peeled tomatoes (canned works too), the mashed garlic, chopped dill, salt, pepper and 1 tsp of dried thyme. Saute for 5 minutes, then remove from heat.
Whisk 2 eggs and pour them into the pan. For the egg-free version, add the psyllium husks instead. Mix well.
Preheat the oven to 180C/350F.
Grease a 9x13-inch rectangular casserole dish with a little olive oil.
Using a mandoline, slice the zucchini into thin slices.
Cover the bottom of the dish with one layer of zucchini slices. Add the mushroom mixture and spread it evenly. Top with a final layer of zucchini slices.
Beat the remaining egg and pour it over the top. Spread it evenly.
Spread 5-6 tablespoons of tomato paste on top and sprinkle with 1 tsp of thyme.
Bake for 35-40 minutes at 180C/350F.
Serve with sour cream - optional.
Notes
Use a 9x13-inch rectangular casserole pan. Leftovers keep in the fridge for up to 3 days and reheat well in the oven. For an egg-free version, swap the eggs for psyllium husks.
