How to Make Eggplant Parmesan
Preheat your oven to 375°F. Slice the zucchini, yellow squash, eggplant, and tomatoes into very thin rounds using a sharp knife or mandoline. Dice the onion and bell pepper, mince the garlic, and prepare the thyme and basil.
Warm two tablespoons of olive oil in an oven-safe skillet over medium heat. Add the onion, bell pepper, most of the salt, and the black pepper, then cook until softened. Stir in the garlic, chopped basil, and part of the thyme, allowing the herbs to release their aroma. Pour in the tomato purée and simmer until the sauce thickens slightly. Finish by stirring in the red wine vinegar and spread the sauce evenly across the bottom of the skillet.
Arrange the sliced vegetables in overlapping circles on top of the tomato sauce, alternating each type to create a colorful presentation. Drizzle with the remaining olive oil and sprinkle the remaining thyme and salt over the vegetables. Cover the skillet with a lid or foil and bake until all the vegetables are tender. Allow the dish to rest for several minutes after baking, then garnish with fresh basil before serving.
Helpful Tips
Slice every vegetable to approximately the same thickness so they cook evenly and create an attractive layered appearance.
Cook the tomato sauce until it becomes slightly thicker before arranging the vegetables. This helps prevent the finished dish from becoming overly watery.
Overlap the vegetable slices closely rather than spreading them apart. This arrangement helps them hold their shape while baking.
Allow the finished bake to rest for about five minutes before serving. The resting time helps the vegetables settle and makes serving much easier.
