This easy vegetarian eggplant lasagna replaces pasta with tender roasted eggplant slices layered with a rich homemade tomato sauce and plenty of melty cheese. No noodles, no breading, no frying—so it’s naturally gluten free—and it has no ricotta, for a lighter, cleaner texture.
We’re building this lasagna with simple components: thinly sliced eggplant roasted until creamy, a concentrated tomato sauce, and a blend of cheeses that melt beautifully. This method avoids pasta entirely—eggplant acts as the layers—making the dish both gluten free and full of summer flavor when eggplant is at its peak.
This version is quick to prepare, avoids frying or breading, and works equally well as a fresh summer main or a baked freezer meal for colder months.
Ingredients for eggplant lasagna
- Eggplant: Choose firm, medium-sized eggplants with smooth skin. Very large specimens can be seedy and bitter. Keep the skin on— it adds texture and helps each slice hold together as a layer.
- Whole milk mozzarella and fontina: Whole milk mozzarella melts better and becomes luscious; fontina adds a mild nuttiness and creaminess. If you can’t find fontina, use all mozzarella.
- Parmesan: Freshly grated Parmigiano-Reggiano brings depth and a nice golden finish when baked.
- Tomatoes: Use quality canned tomatoes for the sauce. A simple homemade sauce concentrates the flavor and keeps the lasagna from becoming watery.
- Aromatics and seasonings: Garlic, a pinch of crushed red pepper for heat (optional), kosher salt, and plenty of fresh basil to finish.
- Extra virgin olive oil: Good oil gives the sauce and roasted eggplant a silky mouthfeel.

Why no ricotta?
Ricotta contains a lot of moisture. Since this recipe uses eggplant instead of pasta to absorb liquids, skipping ricotta keeps the finished lasagna from becoming soggy. The mozzarella and fontina provide the creamy, melty texture we want without excess water.
How to make vegetarian eggplant lasagna
Step 1: Slice, salt, and drain the eggplant
Preheat the oven to 450°F (230°C). Line sheet pans with parchment. Trim the stem from each eggplant and remove a thin strip of skin on one side so you have a stable flat surface for slicing.
Slice each eggplant lengthwise into roughly ½‑inch (1–1.3 cm) planks. A mandoline helps ensure uniform thickness; otherwise use a sharp knife and steady hand. Arrange slices on the pans, salt both sides generously, and let them sit in a colander or bowl for 30 minutes. This step draws out excess moisture and prevents a watery lasagna—don’t skip it.
Step 2: Roast the eggplant
After draining, blot the slices dry with kitchen towels. Brush both sides with olive oil and arrange them on the parchment-lined pans. Roast 30–35 minutes, flipping and rotating pans halfway through, until slices are soft and beginning to color. Reduce oven heat to 400°F (200°C) when ready to assemble the lasagna.
Step 3: Grate the cheeses
While the eggplant drains, grate the mozzarella, fontina, and parmesan. Combine the mozzarella and fontina; keep the parmesan separate to sprinkle between layers and on top. Freshly grating cheese melts better than pre-shredded varieties.
Step 4: Make the tomato sauce
Crush canned tomatoes by hand into a bowl and remove any tough stems. Warm olive oil in a wide, deep skillet or casserole pan until shimmering, then add grated garlic and a pinch of crushed red pepper. Sauté briefly just until fragrant, then add the tomatoes and a splash of water from the can. Bring to a simmer, then lower the heat and cook, stirring frequently, until the sauce thickens and concentrates, about 20 minutes. Season with salt and stir in torn basil at the end if you like.
Step 5: Layer the eggplant lasagna and bake
Assemble in a 9 x 13-inch (23 x 33 cm) baking dish:
- Layer 1: Spread one third of the sauce on the bottom. Arrange a single layer of roasted eggplant, tearing slices if needed to fit. Sprinkle with 1/4 cup grated parmesan, half the mozzarella/fontina mixture, and a few basil leaves.
- Layer 2: Add about half of the remaining sauce, another layer of eggplant, 1/4 cup parmesan, the remaining mozzarella/fontina, and more basil.
- Final Layer: Top with the remaining eggplant, the rest of the sauce, and the remaining parmesan.
Bake at 400°F (200°C) for 30–40 minutes, until the sauce bubbles and the top is lightly golden. Let the lasagna rest 5 minutes before cutting and serving.
Expert tips
- Prevent a watery lasagna: Salt and drain the eggplant, roast until golden and tender, and simmer the tomato sauce long enough to reduce excess liquid.
- Grate fresh cheese: Grating cheese from a block improves meltability and flavor compared with pre-shredded options that often contain anti-caking agents.
- Uniform slices: Aim for consistent eggplant thickness so all slices roast evenly; a mandoline is a helpful tool for this.
Can you freeze vegetarian eggplant lasagna?
Yes. Bake the lasagna first, then cool completely, cover tightly, and freeze for up to two months. Thaw overnight in the refrigerator and reheat covered at 350°F (175°C) until warmed through and bubbling.
Make ahead, storage, reheat
- Make ahead: Roast eggplant and prepare sauce the day before, then assemble and bake when ready. You can also fully bake and refrigerate to reheat the next day.
- Storage: Refrigerate leftovers in an airtight container for up to 4 days.
- Reheat: Warm leftovers in a 350°F (175°C) oven, covered with foil, until heated through and the cheese is bubbling.
What to serve with eggplant lasagna
Pair with a bright green salad, such as massaged kale or mixed greens with lemon dressing, and a simple roasted vegetable side. A light dessert rounds out the meal.

- Pat eggplant dry, brush both sides with olive oil, and roast 30–35 minutes, flipping halfway, until soft and lightly golden. Lower oven to 400°F (200°C).
- While eggplant drains, grate cheeses. Combine mozzarella and fontina; keep parmesan separate.
- Make the sauce: cook garlic and crushed red pepper in ¼ cup olive oil until fragrant, add crushed canned tomatoes and a splash of water, simmer over medium heat, stirring frequently, 20 minutes until thickened. Season with salt and basil if desired.

Notes
- Salting and draining eggplant is essential to prevent excess moisture.
