Provençal Eggplant Tomato Gratin Ingredients

For the Gratin

  • Salt – Draws moisture out of eggplants, reducing bitterness, and is essential for seasoning.
  • Extra-Virgin Olive Oil – Adds richness and helps in cooking the eggplant. Use generously as eggplant absorbs oil.
  • Garlic – Provides aromatic flavor; finely chopped or whole, depending on use.
  • Onion – Sweetness and depth of flavor; caramelizes for a richer sauce.
  • Diced Tomatoes – Forms the base of the sauce; use either canned or fresh for a chunky texture.

  • Herbs de Provence – A blend giving the dish its Provençal character. Can substitute with an Italian herb mix if needed.
  • Black Pepper – Enhances flavor.

For the Cheesy Layer

  • Parmesan Cheese – Provides umami and a golden top; can substitute with pecorino for variation.
  • Mozzarella Cheese – Contributes creaminess and binds ingredients; alternatives include havarti or provolone.

For the Topping

Step‑by‑Step Instructions for Provençal Eggplant Tomato Gratin

Step 1: Prepare Eggplants
Begin by slicing the eggplants into 1/4-inch rounds and layering them on a cutting board. Generously sprinkle salt on both sides of the slices and allow them to sweat for 45 minutes to an hour. This process draws out moisture and bitterness, ensuring a tender texture. Afterward, pat the slices dry with a towel to remove excess moisture.

Step 2: Pan Fry Eggplants
Heat a generous amount of extra-virgin olive oil in a large frying pan over medium heat. Add the salted eggplant slices in batches, cooking them for about 2 minutes on each side until they soften and become golden brown. Remove the cooked eggplant from the pan and set aside on a plate, ensuring they’re ready for assembly in your Provençal Eggplant Tomato Gratin.

Step 3: Make Sauce
In a saucepan, pour in some olive oil and place it over medium heat. Add finely chopped garlic and diced onion, cooking them for about 5 minutes until they become fragrant and caramelized. Stir in the diced tomatoes, fresh basil, Herbs de Provence, black pepper, and a pinch of salt; let the mixture simmer for approximately 20 minutes until it thickens and develops a rich flavor.

Step 4: Assemble Gratin
Take a baking dish and rub the bottom with a clove of garlic and a drizzle of olive oil for extra flavor. Begin layering the dish by placing a layer of eggplant slices, followed by a generous scoop of sauce and a sprinkle of mozzarella and Parmesan cheese. Repeat this process, creating three layers of eggplant, sauce, and cheese, finishing with a topping of breadcrumbs and a sprinkle of extra herbs.

Step 5: Bake
Preheat your oven to 350°F (180°C). Once heated, place the assembled Provençal Eggplant Tomato Gratin in the oven and bake for about 40 minutes. The top should be bubbly and golden brown. For an extra crispy finish, switch to the broiler for 2 minutes, watching closely to prevent burning. Once done, let the gratin cool for about 15 minutes before serving.

Expert Tips for Provençal Eggplant Tomato Gratin

  • Perfect Thickness: Cut eggplants into 1/4-inch rounds for even cooking. Thicker slices may result in undercooked layers, affecting texture.

  • Sweat It Out: Let eggplants sweat for at least 45 minutes to reduce bitterness and moisture. Skipping this step can lead to a soggy gratin.

  • Homemade Sauce Love: Use a homemade tomato sauce for deeper flavor. Store-bought can work, but you’ll miss out on the tailored seasoning.

  • Texture Variation: Opt for panko breadcrumbs if you want extra crunch on top. Regular breadcrumbs can be less crispy but will still taste great.

  • Meal Prep Friendly: Assemble the gratin a day in advance and refrigerate. This allows flavors to meld, enhancing the taste when baked.

  • Guilt-Free Indulgence: Embrace variations! Swap cheese or add extra veggies to customize your Provençal Eggplant Tomato Gratin while keeping it healthy and satisfying.

Make Ahead Options

These Provençal Eggplant Tomato Gratin layers are perfect for meal prep enthusiasts! You can prepare the eggplants and sauce up to 24 hours in advance, which allows the flavors to meld beautifully. Simply salt and sweat the eggplant slices, then store them in an airtight container. The sauce can be made ahead and refrigerated as well. When you’re ready to serve, layer the prepped eggplants, sauce, and cheeses in a baking dish, add breadcrumbs, and bake as directed. This approach ensures your dish retains its delightful texture and flavor—making a delicious meal just as satisfying and perfect for busy weeknights!
