How to Make Eggplant Casserole
Step 1: Preheat the Oven
Preheat your oven to 375°F. Coat a 2 1/2-quart casserole dish with cooking spray to prevent sticking.

In a large skillet, heat the butter and olive oil over medium-low heat.
1. Add in the diced onions and cook for about 3 minutes until soft but not browned.
2. Stir in the diced yellow pepper and minced garlic; continue cooking for another 3 minutes.
3. Add sliced mushrooms to the skillet and cook until they release their moisture, about 3-4 minutes.
4. Mix in diced tomatoes and chopped herbs; let simmer for a couple of minutes before removing from heat.
Step 3: Cook the Eggplant
In the same skillet, heat vegetable oil over medium heat.
1. Add cut eggplant along with salt; cook until lightly browned while stirring frequently.
2. Once browned, sprinkle flour over eggplant and stir well to combine.
3. Return tomato mixture to skillet; mix everything together and bring to a simmer.
Step 4: Assemble the Casserole
Spoon one-third of the vegetable mixture into your prepared baking dish.
1. Top with some Parmesan cheese followed by mozzarella slices.
2. Repeat layering with more vegetable mix and cheese until all ingredients are used up.
3. Finish off with a final layer of cheese on top.
Step 5: Bake and Serve

How to Perfect Eggplant Casserole
Achieving the perfect eggplant casserole is all about technique and careful preparation. Here are some essential tips to ensure your dish stands out.
- Bold Flavoring: Use plenty of fresh herbs to infuse the dish with vibrant flavors. Basil, parsley, and thyme work beautifully together.
- Proper Salting: Salting the eggplant before cooking helps draw out excess moisture and bitterness, enhancing its taste.
- Layering Technique: Layer ingredients thoughtfully—alternate between vegetables and cheese for balanced flavor distribution in every bite.
- Even Cooking: Stir occasionally during cooking to ensure even browning of both eggplant and other vegetables, which enhances overall texture.
- Rest Before Serving: Allowing the casserole to sit for a few minutes after baking lets it set up nicely, making it easier to serve.
Best Side Dishes for Eggplant Casserole

Common Mistakes to Avoid
When making Eggplant Casserole, it’s easy to make simple mistakes. Here are some common pitfalls to avoid:
- Skipping the salting step: Not salting the eggplant can lead to a bitter flavor. Always salt and let it rest to draw out excess moisture.
- Overcooking vegetables: Cooking the vegetables too long before baking can make them mushy. Aim for just tender, then combine with other ingredients.
- Not layering properly: Failing to layer cheese and vegetables correctly can result in uneven cooking. Layer thoughtfully for balanced flavor and texture.
- Ignoring cooking times: Baking for too long can dry out the casserole. Keep an eye on it and remove when the top is golden and bubbly.
- Using low-quality cheese: Cheap cheese doesn’t melt well and may affect the overall taste. Use fresh, high-quality cheeses for the best results.
