1 tbsp olive oil
Salt and black pepper, to taste
1 small red onion, finely chopped
3 garlic cloves, minced
1 cup cherry tomatoes, halved (or 1 can diced tomatoes, drained)
½ tsp dried oregano
½ tsp dried basil
¼ tsp chili flakes (optional)
For the Cheese Mixture:

½ tsp garlic powder

Topping:
1 cup shredded mozzarella cheese
2 tbsp crumbled feta (optional)
Fresh basil or parsley, for garnish
Instructions
Prep the Zucchini
Preheat oven to 190°C (375°F).
Toss sliced zucchini with a bit of salt, then lay them on paper towels for 10 minutes to release excess moisture. Pat dry.
Make the Tomato Base
In a skillet, heat olive oil over medium heat.
Sauté red onion for 3–4 minutes until softened.
Add garlic, cherry tomatoes, oregano, basil, chili flakes, salt, and pepper.
Cook for 5–6 minutes, until tomatoes break down slightly. Set aside.
Make the Cheese Mixture
In a bowl, mix ricotta, Parmesan, egg, garlic powder, nutmeg (if using), salt, and pepper.
Assemble the Casserole
In a greased baking dish:
Spread a layer of tomato-onion mixture on the bottom.
Add a single layer of zucchini rounds.
Spoon over some of the cheese mixture.
Repeat the layers (like lasagna) until all ingredients are used.
Top and Bake
Finish with mozzarella cheese on top, plus crumbled feta if desired.
Bake uncovered for 30–35 minutes, or until bubbling and golden.
