What You’ll Need

• 2 medium eggplants (about 2 pounds total), sliced into 1/2-inch rounds
• 4 large ripe tomatoes, sliced into 1/2-inch rounds
• 1 large yellow onion, thinly sliced
• 3 cloves garlic, minced
• 3 tablespoons extra-virgin olive oil, plus more for the pan
• 1 tablespoon balsamic vinegar (optional, for brightness)
• 1 teaspoon dried oregano
• 1 teaspoon dried basil or Italian seasoning
• 1/2 teaspoon crushed red pepper flakes (optional, for heat)
• 1/2 teaspoon sea salt, plus more to taste
• 1/4 teaspoon freshly ground black pepper
• 1/4 cup fresh parsley or basil, chopped (for garnish)
• 2 tablespoons almond flour or finely ground whole-wheat breadcrumbs (optional, for light topping)
• Lemon wedges, for serving (optional)

Instructions

1. Prep the oven and pan: Preheat your oven to 400°F (200°C).

   Lightly oil a 9×13-inch baking dish or similar casserole pan.

2. Season the eggplant: Arrange the eggplant slices on a cutting board. Sprinkle lightly with salt and let sit for 10–15 minutes to draw out moisture. Pat dry with a clean towel.
3. Make the seasoning oil: In a small bowl, mix the olive oil, minced garlic, oregano, dried basil, red pepper flakes, salt, black pepper, and balsamic vinegar (if using).
4. Layer the vegetables: Place half the onion slices in the bottom of the baking dish.

   Layer eggplant and tomato slices, alternating them in overlapping rows. Tuck the remaining onion slices throughout.

5. Drizzle and coat: Spoon the seasoned oil evenly over the vegetables, making sure the tops are well coated. Use the back of the spoon to spread it around.
6. Optional topping: Sprinkle almond flour or whole-wheat breadcrumbs lightly over the top for a delicate crust.
7. Bake: Cover with foil and bake for 25 minutes.

   Remove the foil and bake another 20–25 minutes, until the eggplant is tender and the tomatoes are bubbling and slightly caramelized around the edges.

8. Rest and garnish: Let the bake rest for 5–10 minutes so the juices settle. Sprinkle with fresh parsley or basil. Serve with lemon wedges if you like a bright finish.

Keeping It Fresh

• Storage: Store leftovers in an airtight container in the fridge for up to 4 days.
• Reheating: Warm in a 350°F (175°C) oven for 10–15 minutes or microwave in short bursts.

  Add a drizzle of olive oil if it looks dry.

• Freezing: This dish can be frozen, but the texture will soften. If freezing, cool completely, wrap well, and freeze up to 2 months. Thaw overnight in the fridge and reheat in the oven.
• Make-ahead: Assemble up to 12 hours in advance, cover, and refrigerate.

  Bake just before serving.

Benefits of This Recipe

• Vegetable-forward: Eggplant and tomatoes bring fiber, vitamins, and antioxidants with minimal calories.
• Healthy fats: Olive oil adds heart-healthy monounsaturated fats and helps absorb fat-soluble nutrients.
• Low effort, high reward: Minimal chopping and straightforward steps make it perfect for busy nights.
• Gluten-free and dairy-free options: Keep the topping light with almond flour or skip it entirely.
• Clean flavors: Herbs and garlic pack flavor without heavy sauces or additives.

Common Mistakes to Avoid

• Skipping the eggplant salt-and-pat step: This quick step helps prevent sogginess and bitterness.
• Under-seasoning: Eggplant benefits from enough salt and herbs. Taste and adjust before baking.
• Too much liquid: Very ripe tomatoes can release a lot of juice. Baking uncovered at the end helps reduce excess moisture.
• Overcrowding the pan: If your pan is too small, the vegetables steam instead of roast.

  Use a roomy dish for best texture.

• Skipping the rest: Letting the bake sit for a few minutes after cooking helps the flavors settle and makes it easier to serve.

Recipe Variations

• Herb-forward: Add fresh thyme or rosemary before baking for a savory, woodsy flavor.
• Protein boost: Scatter cooked chickpeas between layers for extra protein and fiber.
• Mediterranean twist: Add olives and capers for briny pops of flavor. Use sparingly so it stays balanced.
• Spice it up: Swap red pepper flakes for a pinch of smoked paprika or Aleppo pepper.
• Cheesy, still clean: If you eat dairy, finish with a light sprinkle of goat cheese or grated Parmesan right after baking.
• Zucchini swap: Replace half the eggplant with sliced zucchini for a lighter texture and a mix of flavors.
• Pesto drizzle: Finish with a small spoonful of dairy-free basil pesto for freshness and color.

FAQ

Do I need to peel the eggplant?

Most of the time, no. The skin softens as it bakes and adds color and nutrients.

If your eggplant is very large or thick-skinned, peel partially with a few lengthwise stripes.

Can I use canned tomatoes?

Yes, but choose whole or thick-cut canned tomatoes and drain them well. Fresh tomatoes give better texture, but canned can work in a pinch.

How do I keep the bake from getting watery?

Lightly salt and pat the eggplant dry, use firm tomatoes, and bake uncovered for the last 20–25 minutes. If there’s still excess liquid, let it rest and spoon off a bit before serving.

What should I serve with it?

It’s great with quinoa, brown rice, or a simple green salad.

For extra protein, add grilled chicken, baked tofu, or white beans on the side.

Can I make this oil-free?

You can. Swap the olive oil for a splash of low-sodium vegetable broth to moisten the layers. The result will be less rich, but still flavorful with the herbs and garlic.

Is this recipe kid-friendly?

Usually yes.

Keep the red pepper flakes out, slice the eggplant a bit thinner, and bake until very tender. A sprinkle of mild cheese can help picky eaters.

How do I choose a good eggplant?

Look for smooth, shiny skin with no soft spots, and pick one that feels heavy for its size. Press lightly; it should bounce back without leaving a dent.

Can I add greens?

Absolutely.

Layer a handful of baby spinach or chopped kale between the vegetables. Kale holds up well; spinach will melt into the sauce.
