Baked Eggplant and Tomato Stacks

Of all the vegetarian dishes that have graced my family’s dinner table, few have received the universal, silent-then-enthusiastic approval as these Baked Eggplant and Tomato Stacks. The first time I made them, I was met with skepticism. Eggplant, for my kids, was a culinary mystery, a vegetable they eyed with suspicion. But as the aroma of baking garlic, sweet tomatoes, and melting cheese filled the kitchen, their curiosity piqued. When I finally pulled the baking dish from the oven, revealing towering stacks of vibrant red and deep purple, crowned with a golden, bubbling cap of cheese and breadcrumbs, the skepticism melted away. The first bite was a revelation—the eggplant was creamy and savory, not bitter or spongy, perfectly complemented by the bright acidity of the tomato and the rich, stringy pull of mozzarella. It was like a healthier, more elegant version of eggplant Parmesan, and it instantly became a staple in our home. This dish proves that simple, fresh ingredients, when layered with a little love and care, can create something truly spectacular. It’s elegant enough to serve to dinner guests yet simple enough for a satisfying weeknight meal, and it’s a recipe I am truly excited to share in its entirety, complete with every tip and trick I’ve learned along the way.

Ingredients

• 2 large Globe eggplants (about 2.5 lbs total): Look for eggplants that are firm, heavy for their size, with smooth, shiny skin. These will have fewer seeds and a less bitter taste.
• 1 ½ teaspoons kosher salt, divided, plus more for salting: Kosher salt is key for drawing moisture out of the eggplant slices effectively.
• ½ cup Panko breadcrumbs: These Japanese-style breadcrumbs are lighter and flakier than traditional breadcrumbs, creating a wonderfully crispy and golden topping.
• ¼ cup grated Parmesan cheese: For the best flavor, use a freshly grated block of Parmigiano-Reggiano. It adds a nutty, salty depth that pre-grated cheese can’t match.
• 2 cloves garlic, minced: Freshly minced garlic provides a pungent, aromatic foundation for the topping.
• 1 teaspoon dried oregano: This classic Italian herb infuses the dish with a warm, peppery flavor that pairs beautifully with tomato and eggplant.
• ¼ teaspoon black pepper, freshly ground: Freshly ground pepper offers a more potent and complex flavor than pre-ground.
• 4 large Roma tomatoes (about 1 lb): Roma or plum tomatoes are ideal for this recipe as they have a lower water content and a meatier texture, which prevents the stacks from becoming soggy.
• 8 ounces fresh mozzarella cheese, sliced into 8 rounds: Fresh mozzarella offers a superior creamy texture and milky flavor. Slicing it from a log or ball is preferable to pre-shredded varieties.
• ¼ cup fresh basil leaves, chopped or torn: Basil adds a fresh, sweet, and slightly peppery note that cuts through the richness of the cheese.
• ¼ cup extra virgin olive oil: A good quality olive oil is used for roasting the eggplant, adding flavor and helping it to become tender and golden.

Instructions

1. Prepare the Eggplant (The Crucial First Step): Begin by preheating your oven to 400°F (200°C). Line two large baking sheets with parchment paper for easy cleanup. Wash and dry the eggplants, then trim off the stem and bottom ends. Slice the eggplants crosswise into ½-inch thick rounds. For the most stable stacks and even cooking, try to make the slices as uniform in thickness as possible.
2. Salt and Sweat the Eggplant: Arrange the eggplant slices in a single layer on the prepared baking sheets (or use a colander). Sprinkle both sides of each slice generously with kosher salt. Let the slices sit for 30 to 45 minutes. You will see beads of water form on the surface. This “sweating” process is vital; it draws out excess moisture and some of the eggplant’s natural bitterness, resulting in a creamier texture and preventing the final dish from being watery.
3. Rinse and Dry: After the sweating period, thoroughly rinse the eggplant slices under cool running water to remove all the salt. Gently pat each slice completely dry with paper towels or a clean kitchen towel. This is another key step to ensure the eggplant roasts to a beautiful golden brown rather than steaming.
4. Roast the Eggplant: Clean the baking sheets and re-line them with fresh parchment paper if needed. Arrange the dried eggplant slices in a single layer. Brush both sides of each slice with extra virgin olive oil. Roast in the preheated oven for 20-25 minutes, flipping the slices halfway through, until they are tender and lightly golden brown. Roasting first ensures the eggplant is fully cooked and develops a deeper flavor.
5. Prepare the Topping and Tomatoes: While the eggplant is roasting, prepare the other components. In a small bowl, combine the Panko breadcrumbs, grated Parmesan cheese, minced garlic, dried oregano, ½ teaspoon of the kosher salt, and the freshly ground black pepper. Mix well until everything is evenly distributed. Slice your Roma tomatoes into ¼-inch thick rounds.
6. Assemble the Stacks: Remove the roasted eggplant from the oven. Reduce the oven temperature to 375°F (190°C). Select the 8 largest, most stable eggplant slices to serve as the bases for your stacks. Place these on one of the parchment-lined baking sheets. Begin layering: on top of each base slice, place a slice of tomato, a slice of fresh mozzarella, and a few pieces of fresh basil.
7. Build the Second Layer: Top the first layer with a slightly smaller eggplant slice. Repeat the layering process: add another slice of tomato, another slice of mozzarella, and more fresh basil.
8. Add the Crispy Topping: Carefully spoon the Panko-Parmesan mixture evenly over the top of each stack, pressing down gently so it adheres to the top layer of mozzarella.
9. Bake the Stacks: Place the baking sheet back into the 375°F (190°C) oven. Bake for 15-20 minutes, or until the mozzarella is fully melted and bubbly, and the breadcrumb topping is a deep golden brown.
10. Rest and Serve: Carefully remove the stacks from the oven. Let them rest on the baking sheet for at least 5-10 minutes. This allows the layers to set, making them easier to transfer to plates without toppling over. Garnish with any remaining fresh basil before serving.

Additional tips

1. The Salting Secret is Non-Negotiable: I cannot stress this enough. Skipping the salting step will result in eggplant that is spongy, watery, and potentially bitter. This 30-minute step is the single most important key to achieving a perfectly creamy, savory eggplant texture.
2. Uniform Slices for Stability: Take your time when slicing the eggplant and tomatoes. Slices of a consistent thickness will cook evenly and, more importantly, stack securely. A wobbly base from an uneven slice can cause your beautiful tower to topple in the oven. A sharp serrated knife often works best for tomatoes.
3. Don’t Crowd the Pan When Roasting: When you first roast the eggplant slices, ensure they are in a single layer with a bit of space between them. Overcrowding the pan will cause them to steam instead of roast, preventing them from browning and developing that deep, concentrated flavor. Use two baking sheets if necessary.
4. Customize Your Crumb Topping: The Panko topping is a canvas for flavor. Feel free to add a pinch of red pepper flakes for heat, a teaspoon of lemon zest for brightness, or other dried herbs like thyme or rosemary to the breadcrumb mixture.
5. Experiment with Cheeses: While classic mozzarella and Parmesan are a match made in heaven, don’t be afraid to experiment. Slices of provolone will add a sharper, smokier flavor. Fontina cheese will provide an even meltier, nuttier experience. A dollop of ricotta cheese on one of the layers can also add incredible creaminess.
6. Make-Ahead Magic for Easy Assembly: You can make this recipe much quicker on a busy night by prepping ahead. The eggplant slices can be salted, rinsed, dried, and roasted a day in advance. Store them in an airtight container in the refrigerator. You can also mix the breadcrumb topping ahead of time. When you’re ready to eat, all you have to do is assemble and bake.
7. Choosing the Right Tomatoes Matters: As mentioned in the ingredients, Roma or plum tomatoes are best because of their low water content. If you only have large, juicy beefsteak tomatoes, you can still use them. Simply slice them and let them sit on paper towels for about 15 minutes to absorb some of the excess moisture before layering.
8. Broil for an Extra Crispy Top: If you love a deeply browned, extra-crispy cheese and breadcrumb crust, you can place the stacks under the broiler for the final 1-2 minutes of cooking. Watch them like a hawk, as the topping can go from golden to burnt in a matter of seconds.

FAQ section

1. Can I make these Baked Eggplant and Tomato Stacks vegan?
Absolutely! This recipe is very adaptable for a vegan diet. Simply swap the mozzarella and Parmesan for your favorite plant-based alternatives. Use a high-quality vegan mozzarella that melts well, and substitute nutritional yeast or a vegan Parmesan for the topping to achieve that cheesy, nutty flavor.

2. How can I make this recipe gluten-free?
This is an easy switch. Just substitute the Panko breadcrumbs with your favorite gluten-free breadcrumbs. Many brands offer a panko-style gluten-free version that will give you a similarly crispy result. The rest of the ingredients are naturally gluten-free.

3. My eggplant stacks turned out soggy. What did I do wrong?
Sogginess is the most common issue and almost always comes down to one of three things: 1) You skipped or rushed the salting process, which didn’t remove enough water from the eggplant. 2) You didn’t pat the eggplant slices completely dry after rinsing. 3) You used very watery tomatoes. Ensure you follow the salting and drying steps meticulously for the best results.

4. How do I store and reheat leftovers?
Leftover stacks can be stored in an airtight container in the refrigerator for up to 3-4 days. The breadcrumb topping will lose its crispness. The best way to reheat them and bring back some of the texture is in an oven or toaster oven at 350°F (175°C) for 10-15 minutes, or until warmed through. Microwaving will work but will result in a softer texture.

5. Can I freeze these eggplant stacks?
Yes, you can freeze them, though the texture will change slightly upon reheating. For best results, assemble and bake the stacks completely, then let them cool. Wrap them individually in plastic wrap and then place them in a freezer-safe bag or container. They can be frozen for up to 2 months. Reheat directly from frozen in a 375°F (190°C) oven for 25-30 minutes, or until hot and bubbly.

6. Can I use a different vegetable instead of eggplant?
Certainly. Large zucchini or yellow squash are excellent substitutes. Slice them into thick rounds and proceed with the recipe. The good news is that zucchini doesn’t typically require the extensive salting process that eggplant does, which can save you some time.

7. Why did my beautiful stacks fall over?
A toppled stack can be disappointing! This usually happens if the base slice is too small or unstable, or if the slices are cut unevenly, creating a lean. It can also happen if you try to move them to a plate too soon after they come out of the oven. Letting them rest for 5-10 minutes is key, as it allows the cheese to set up and act as a delicious “glue” holding the layers together.

8. Is this recipe considered healthy?
Yes, this is a very healthy and well-rounded dish. It’s packed with vegetables and fiber. By baking the eggplant instead of frying it, you significantly reduce the amount of oil and calories compared to traditional eggplant Parmesan. It’s a great way to enjoy a rich, cheesy, and satisfying meal that is also full of nutrients.
