Ingredients

Yield: About 8 servings

• ▢2 medium eggplant, sliced about 1/4″ thick
• ▢4 tablespoons olive oil
• ▢sea salt
• ▢ground black pepper
• ▢1 recipe Marinara Sauce, full recipe
• ▢3 pounds ground beef, cooked and drained (optional)
• ▢15 ounces whole Ricotta cheese
• ▢3 large eggs
• ▢1 cup grated Parmesan cheese
• ▢1 1/2 cups grated Mozzarella cheese

Make the Marinara

A bright, well-seasoned marinara is the backbone of this Easy Eggplant Lasagna Recipe. If you already have a favorite jarred sauce you love, use that. Otherwise, prepare a simple marinara: sauté garlic in olive oil, add crushed tomatoes, a pinch of sugar if the tomatoes are too acidic, salt, pepper, and a handful of fresh basil or dried Italian seasoning. Let it simmer until it thickens slightly. You want a saucy texture that will cling to the eggplant without making the casserole watery.

Prep the eggplant

Preheat your oven to 425°F (220°C). Arrange the eggplant slices in a single layer on baking sheets. Brush both sides lightly with olive oil and season with sea salt and ground black pepper. Roast the eggplant for 8–12 minutes total, flipping halfway, until slices are tender and beginning to brown at the edges. Remove from the oven and set aside to cool briefly. Roasting concentrates the flavor and prevents the final dish from becoming watery.

Cook the beef (optional)

If you’re including the optional ground beef, brown it in a large skillet over medium-high heat until no longer pink, breaking it into small pieces as it cooks. Season with a little salt and pepper. Drain any excess fat and set the cooked beef aside. Use exactly 3 pounds cooked and drained, as listed in the ingredient list.

Prepare the ricotta filling

In a medium bowl, whisk together 15 ounces whole ricotta cheese, 3 large eggs, and 1 cup grated Parmesan cheese until smooth and well combined. Season with a little salt and ground black pepper to taste. This mixture will become creamy and set during baking, helping the lasagna maintain structure when you slice it.

Assemble the lasagna

Place your oven rack in the middle position and reduce oven temperature to 375°F (190°C). In a 9×13-inch baking dish or a similar-sized ovenproof pan, spread a thin layer of marinara sauce across the bottom to prevent sticking and create a flavor base. Layer the components as follows, keeping the same overall order and ingredient amounts as listed:

1. Lay a single layer of roasted eggplant slices over the sauce, slightly overlapping as needed to cover the surface.
2. Spoon about one-third of the marinara sauce evenly over the eggplant layer.
3. If you are using the optional ground beef, scatter one-third of the cooked and drained ground beef over the sauce layer. If you are not using the beef, skip this step and simply use more sauce where desired.
4. Spoon one-third of the ricotta mixture in dollops across the pan, then gently spread it to form an even layer without disturbing the eggplant beneath.
5. Sprinkle a portion of the grated mozzarella (about one-third) across the ricotta layer.
6. Repeat these layers two more times—eggplant, marinara, optional beef, ricotta mixture, and mozzarella—so you complete three total layers. Finish by spooning any remaining marinara over the top, then sprinkle the remaining mozzarella and any leftover Parmesan if desired.

Bake

Cover the baking dish loosely with foil and bake in the preheated 375°F (190°C) oven for 25 minutes. Remove the foil and continue baking for another 15–20 minutes, or until the top is bubbly and the cheeses are melted and beginning to turn golden. If you prefer a deeply browned top, place the dish under the broiler for 1–2 minutes—watch closely so it doesn’t burn.

Rest and serve

Once baked, remove the lasagna from the oven and let it rest for at least 10–15 minutes before slicing. Resting helps the ricotta custard set so each slice holds together cleanly. Serve warm, garnished with extra grated Parmesan, a drizzle of olive oil, or torn fresh basil leaves if you like. A simple green salad and warm crusty bread make great accompaniments.

Tips and variations

• Make it vegetarian: Omit the cooked ground beef and increase the marinara or add a layer of sautéed mushrooms, zucchini, or spinach for extra body.
• Salt the eggplant (optional): If you prefer, you can sprinkle the raw slices with salt and let them rest for 20–30 minutes to draw out moisture and any bitterness. Rinse and pat dry before brushing with oil and roasting. This step is optional when you roast at high heat.
• Cheese swap: Use part-skim ricotta for a lighter filling, or mix in 1/2 cup shredded Parmesan directly into the mozzarella layer for more savory depth.
• Advance prep: Assemble the lasagna up to 24 hours ahead, cover, and refrigerate. Bring to room temperature for 20 minutes before baking and add 10–15 minutes to the covered baking time if baking from chilled.

How to store and reheat

Cool any leftovers completely, then cover and refrigerate for up to 4 days. To reheat, warm individual slices in the microwave or reheat the whole dish in a 350°F (175°C) oven, covered, until heated through—about 20–30 minutes, depending on size. For freezer storage, wrap portions tightly and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

Frequently asked questions

Can I peel the eggplant? You can, but leaving the skin on helps the slices hold together during roasting and baking. The skin becomes tender and adds color to the finished dish.

Do I need to pre-cook the eggplant? Yes—roasting or grilling the slices first concentrates flavor and removes excess moisture so the lasagna doesn’t become soggy.

How long will the assembled lasagna keep its shape? After a 10–15 minute rest, the ricotta custard sets and the lasagna slices hold together well for serving. If you try to slice it immediately out of the oven, the layers may be too loose.
