How to Make Eggplant Parmesan
Preheat the oven to 375°F. Using a sharp knife or mandoline, slice the zucchini, yellow squash, eggplant, and tomatoes into thin, even rounds. Dice the onion and bell pepper, mince the garlic, and prepare the fresh herbs.
Heat two tablespoons of olive oil in an oven-safe skillet over medium heat. Cook the onion and bell pepper with most of the salt and black pepper until softened. Add the garlic, chopped basil, and part of the thyme, then cook briefly until fragrant. Stir in the tomato purée and let it simmer until it thickens slightly. Finish by mixing in the red wine vinegar, then spread the sauce into an even layer.
Arrange the sliced vegetables over the tomato sauce in overlapping circles, alternating each variety to create a colorful pattern. Drizzle the remaining olive oil across the top and sprinkle with the remaining thyme and salt. Cover the skillet with a lid or foil and bake until all of the vegetables become tender. Let the dish cool for about five minutes, then garnish with fresh basil before serving.
Helpful Tips
Cut the vegetables into slices of equal thickness so they cook evenly and create a neat presentation.
Allow the tomato sauce to simmer before assembling the vegetables. A slightly thicker sauce helps maintain the ideal consistency during baking.
Layer the vegetables closely together with a slight overlap. This arrangement helps them cook evenly while producing an attractive finished dish.
After baking, let the casserole rest briefly. This simple step allows the sauce to settle and makes serving much easier.

Frequently Asked Questions
What vegetables are traditionally used in Ratatouille?
Traditional ratatouille features eggplant, zucchini, yellow squash, tomatoes, onions, bell peppers, garlic, and fresh herbs such as thyme and basil. These ingredients create the dish’s signature flavor and colorful appearance.
How do you keep Ratatouille from becoming watery?
Use evenly sliced vegetables, reduce the tomato sauce before assembling the dish, and avoid overcrowding the vegetables. Baking until they are tender rather than overcooked also helps maintain a balanced texture.
Can you make Ratatouille ahead of time?
Yes. The vegetables can be sliced and the dish fully assembled one day in advance. Refrigerate it until ready to bake, then allow a few additional minutes in the oven if cooking directly from the refrigerator.
How do you store and reheat Ratatouille?
After cooling completely, transfer leftovers to an airtight container and refrigerate for up to three days. Reheat gently in the oven or microwave until thoroughly warmed before serving.
Storage Instructions
Allow the vegetable bake to cool before storing it in a tightly sealed container. Refrigerate for up to three days. To reheat, warm individual portions in the microwave or place the entire dish in a 350°F oven until heated through. Many people enjoy the leftovers even more because the herbs and vegetables continue to develop flavor after resting overnight.
