Provencal Eggplant Tomato Gratin Ingredients

For the Gratin

  • Eggplants – The star of this dish; offers a meaty texture perfect for layering.
  • Salt – Essential for drawing moisture from eggplants and enhancing flavor.
  • Extra-Virgin Olive Oil – Adds richness when frying; feel free to use your favorite neutral oil if in a pinch.
  • Garlic (5 cloves total) – Fresh garlic enhances the aromatic depth of the dish; skip the powder for better results.
  • Onion – Provides a sweet base for the sauce; you can substitute with shallots for a subtler flavor.
  • Diced Tomatoes (28 fl. oz can) – Forms the flavorful core of the sauce; swap for fresh tomatoes for a chunkier bite.

  • Herbs de Provence – A blend of fragrant herbs that bring authenticity to your Provencal Eggplant Tomato Gratin.
  • Black Pepper – For seasoning; freshly ground black pepper enhances the flavor profile.
  • Parmesan Cheese (¼ cup) – Adds a nutty flavor and helps bind the layers together; consider pecorino as a zesty alternative.

Step‑by‑Step Instructions for Provençal Eggplant Tomato Gratin

Step 1: Sweat the Eggplant
Begin by slicing the eggplants into ¼-inch rounds and laying them on paper towels. Generously sprinkle salt over the slices to draw out moisture and bitterness. Let them rest for 45 minutes, allowing the salt to do its work. Once the time is up, pat the slices dry with another paper towel to remove excess moisture.

Step 2: Pan-Fry Eggplant
In a large skillet, heat 2 tablespoons of extra-virgin olive oil over medium heat. Carefully add the eggplant slices in a single layer, frying them for about 2 minutes on each side until they turn golden and soften. Be patient and repeat this process with all the slices, adding more oil as needed to prevent sticking.

Step 3: Prepare Tomato Sauce
In a saucepan, heat 1 tablespoon of olive oil over medium heat. Sauté chopped onion and minced garlic until they become fragrant and golden, which takes about 5 minutes. Next, stir in the diced tomatoes, herbs de Provence, fresh basil, salt, and black pepper. Simmer the sauce for 20 minutes, stirring occasionally, until it thickens to a rich consistency.

Step 4: Assemble the Gratin
Preheat your oven to 350°F (180°C). Grease a baking dish with olive oil or cooking spray to prevent sticking. Layer half of the fried eggplant slices evenly across the bottom of the dish. Spread half of the prepared tomato sauce on top, then sprinkle with half of the Parmesan and mozzarella cheeses. Repeat the layers, finishing with the remaining sauce and top with the cheeses and a light sprinkle of breadcrumbs for added crunch.

Step 5: Bake
Place the assembled Provençal Eggplant Tomato Gratin in the preheated oven. Bake for approximately 40 minutes, or until the top is bubbling and golden brown. For an extra crispy finish, switch to the broiler for an additional 2 minutes, keeping an eye on it to prevent burning.

Step 6: Cool and Serve
After baking, remove the gratin from the oven and let it cool for at least 15 minutes. This resting period allows the flavors to meld and the gratin to set, ensuring easy serving. Slice into portions and serve warm, perhaps alongside a fresh salad or crusty bread for a delightful meal.

Expert Tips for Provençal Eggplant Tomato Gratin

Uniform Slices: Ensure your eggplant slices are uniformly ¼ inch thick for consistent cooking. Thicker slices may remain chewy, so evenness is key.

Sweating the Eggplant: Always sweat your eggplants with salt to draw out moisture and bitterness. Skipping this step can lead to a watery gratin.

Cooling Time: Let the gratin rest for at least 15 minutes after baking. This cooling time is essential for the layers to set properly, making it easier to serve.

Cheese Variety: Feel free to experiment with cheeses! Try different combinations for a unique take on this Provençal Eggplant Tomato Gratin, or use lactose-free options if needed.

Fresh Herbs: Whenever possible, use fresh basil and herbs de Provence. They elevate the flavor profile and bring a taste of summer into your kitchen.

Storage Savvy: Store leftovers in an airtight container in the fridge for 4–5 days. Reheat in the oven for the best texture, restoring that bubbly goodness!

Provencal Eggplant Tomato Gratin Recipe FAQs

What should I look for when selecting eggplants?
Absolutely! When choosing eggplants, look for firm, glossy skin without any dark spots or blemishes. A ripe eggplant should feel heavy for its size and have a slight give when gently pressed. Always opt for smaller to medium-sized eggplants, as they tend to have fewer seeds and a less bitter flavor.

How should I store leftover Provencal Eggplant Tomato Gratin?
Very! Once your gratin has cooled, store leftovers in an airtight container in the fridge for up to 4-5 days. To reheat, simply place it in the oven at 350°F for around 20 minutes or until heated through. This method helps retain that bubbly, cheesy goodness!

Can I freeze the gratin, and if so, how?
Of course! To freeze the Provencal Eggplant Tomato Gratin, first allow it to cool completely. Then, cut it into individual portions and wrap each portion tightly in plastic wrap. Place the wrapped portions in a freezer-safe container or bag. It will keep well for up to 2 months. When you’re ready to enjoy it, thaw overnight in the refrigerator and reheat in the oven at 350°F for about 20 minutes until warmed through.

What if my eggplant is too bitter?
If you find your eggplant to be bitter, ensure you sweat it properly before cooking. This process involves sprinkling the sliced eggplant with salt and letting it sit for 45 minutes to draw out moisture and bitterness. Afterward, rinse and pat dry. If you still find it too bitter, consider applying more salt in the cooking process, or mix it with milder vegetables like zucchini for a balanced flavor.

Is this dish safe for people with dairy allergies?
The Provencal Eggplant Tomato Gratin contains cheese and other dairy products, so it’s not suitable for those with dairy allergies. However, you can easily adapt the recipe by using plant-based cheese alternatives or simply omitting the cheese altogether. The gratin will still retain its delicious flavor and satisfy your cravings!

Can I use fresh tomatoes instead of canned for the sauce?
Absolutely! You can substitute the canned diced tomatoes with fresh tomatoes for a chunkier texture. You’ll need about 4-5 medium ripe tomatoes. To use fresh tomatoes, score the bottoms with an “X,” blanch them in boiling water for 30 seconds, then transfer them to an ice bath. This makes it easier to peel off the skins. Chop and add them to your sauce following the same instructions!
