Step-by-Step Guide for Eggplant Casserole
Step 1: Prepare the Eggplant
Wash and trim the eggplants. Slice them into even rounds about ¼-inch thick. Arrange slices on a tray or cutting board and sprinkle both sides lightly with salt.
Let them rest for 25 to 30 minutes. This removes excess moisture and reduces bitterness.
Pat dry thoroughly with paper towels.
Brush each slice lightly with olive oil and season with black pepper.
Step 2: Pre-Cook the Eggplant
Preheat the oven to 425°F (220°C).
Place eggplant slices in a single layer on baking sheets lined with parchment paper. Roast for 15 to 20 minutes, turning halfway through, until lightly golden and softened.
This step is essential for a firm casserole texture.
Remove from oven and set aside.
Step 3: Make the Tomato Sauce
Heat olive oil in a skillet over medium heat.
Add chopped onion and cook for 5 minutes until softened. Stir in minced garlic and cook for 30 seconds.
Add:
- Crushed tomatoes
- Tomato paste
- Oregano
- Basil
- Salt
- Pepper
- Red pepper flakes
- Sugar (if using)
Simmer uncovered for 15 minutes, stirring occasionally, until thick and fragrant.
The sauce should be rich, not watery.
Step 4: Prepare the Baking Dish
Reduce oven temperature to 375°F (190°C).
Lightly grease a 9×13-inch baking dish with olive oil.
Spread a thin layer of tomato sauce across the bottom. This prevents sticking and starts flavor-building from the first layer.
Step 5: Build the Eggplant Casserole Layers
Layer in this order:
- Sauce
- Roasted eggplant slices
- Ricotta dollops
- Mozzarella
- Parmesan
Repeat until all ingredients are used, finishing with sauce and a generous top layer of mozzarella and Parmesan.
For best structure, create 2 to 3 complete layers.
Step 6: Bake Until Golden
Cover loosely with foil and bake for 25 minutes.
Remove foil and continue baking for 15 to 20 minutes until the top is golden, bubbling, and beautifully melted.
For extra color, broil for 2 minutes at the end.
Watch closely.
Step 7: Rest Before Serving
Remove from oven and allow the casserole to rest for 10 to 15 minutes before slicing.
This helps layers settle and makes serving easier.
Top with chopped parsley or fresh basil.
Serving Suggestions
Eggplant casserole pairs beautifully with:
- Garlic bread
- Green salad
- Roasted vegetables

- Grilled chicken
Serve hot for maximum flavor and texture.
