Ricotta Eggplant Casserole

The first time I made this casserole, my kitchen filled with this incredible aroma of roasting eggplant and bubbling cheese that had my neighbor knocking on my door to ask what I was making. I hadnt planned on company that night, but the smell was too inviting to ignore, so we ended up sharing impromptu plates right there on the counter while it was still too hot to eat properly.

Last winter when my sister came over exhausted from work, I pulled this casserole out of the oven. She took one bite and actually teared up a little, saying it reminded her of the Sunday dinners at our grandmothers house that we both missed so much. Now she requests it every time she visits, and Ive stopped even asking what she wants for dinner.

Ingredients

• 2 large eggplants, sliced lengthwise into 1/2 inch thick slices: Look for firm, glossy eggplants without soft spots, and try to slice them evenly so they roast at the same rate
• 2 tbsp olive oil: This helps the eggplant caramelize beautifully instead of just steaming in the oven
• 1/2 tsp salt and 1/4 tsp black pepper: Simple seasoning that transforms the eggplants natural flavor
• 2 cups ricotta cheese: Whole milk ricotta gives the best texture, but part skim works if you are watching calories
• 1/2 cup grated Parmesan cheese: Adds a salty, umami depth that balances the mild ricotta
• 1 large egg: This binds the ricotta mixture so it doesnt separate during baking
• 2 tbsp fresh basil, chopped: Fresh basil makes a huge difference here, but use 1 tsp dried if thats what you have
• 1/4 tsp ground nutmeg: My grandmothers secret ingredient that makes the cheese filling taste special
• 3 cups marinara sauce: Use your favorite homemade recipe or a good quality store bought version
• 2 cups shredded mozzarella cheese: Low moisture mozzarella melts better without making the dish too watery
• 2 tbsp grated Parmesan cheese: For that golden, salty crust on top
• Fresh basil leaves: The finishing touch that adds a pop of fresh flavor and color

Instructions

Roast the eggplant:

Preheat your oven to 400°F and line two baking sheets with parchment paper. Arrange the eggplant slices in a single layer, brush both sides with olive oil, and season with salt and pepper. Roast for 20 minutes, flipping halfway through, until theyre softened and lightly golden.

Prepare the cheese filling:

While the eggplant roasts, mix the ricotta, Parmesan, egg, basil, nutmeg, salt, and pepper in a bowl until smooth. The mixture should be creamy and spreadable, not stiff.

Start layering:

Reduce oven temperature to 375°F. Spread 1/2 cup marinara on the bottom of a 9x13 inch baking dish. Layer half the roasted eggplant over the sauce, then spread half the ricotta mixture, 1 cup marinara, and 1 cup mozzarella.

Repeat and finish:

Add the remaining eggplant, ricotta mixture, marinara, and mozzarella. Sprinkle the top with the remaining 2 tbsp Parmesan.

Bake until bubbly:

Cover with foil and bake for 25 minutes. Remove foil and bake another 15 to 20 minutes until the cheese is golden and bubbling around the edges.

Rest before serving:

Let the casserole rest for 10 minutes before cutting. This is crucial or the layers will slide apart when you serve it.

This recipe became a staple in our house during those long winter months when everyone needed something warm and comforting to come home to. My teenage son, who usually turns his nose up at anything with eggplant, actually asked for seconds the first time I made it, which might be the highest compliment a cook can receive.

Make It Your Own

I have learned that this casserole is incredibly forgiving and adaptable. Sometimes I add a layer of sautéed spinach or mushrooms between the eggplant and ricotta for extra vegetables and depth of flavor. Other times I will sprinkle in some red pepper flakes if we are craving a little heat.

Time Saving Tips

You can roast the eggplant and make the ricotta mixture up to two days ahead. Just store them separately in the refrigerator and assemble when you are ready to bake. I have also assembled the entire casserole the night before and kept it covered in the fridge, adding about 10 minutes to the baking time.

Serving Suggestions

This casserole is satisfying enough to stand alone, but I love serving it with a crisp green salad dressed with vinaigrette to cut through the richness. Crusty bread is essential for soaking up any extra sauce on your plate.

• A light Italian red wine like Chianti pairs beautifully with the tomato and cheese
• If you have leftovers, they reheat wonderfully for lunch the next day
• The casserole freezes well for up to three months if you want to make a double batch

There is something deeply satisfying about serving a dish that looks impressive but comes together with such simple ingredients. This casserole has become my go to for bringing to new neighbors or friends who need a little comfort in their lives.

Recipe FAQs

→ Can I make this ahead of time?

Yes, assemble the entire dish up to 24 hours in advance and refrigerate. Add 10-15 minutes to the baking time if baking cold from the refrigerator.

→ Do I need to salt and drain the eggplant first?

Salting isn't strictly necessary since the eggplant is roasted, but if you have time, salting slices for 30 minutes and patting dry can reduce bitterness and absorb less oil during roasting.

→ Can I freeze this casserole?

Yes, freeze before baking or after cooling completely. Wrap tightly in plastic and foil for up to 3 months. Thaw overnight in the refrigerator before baking as directed.

→ What can I use instead of ricotta?

Cottage cheese blended until smooth or a mixture of mascarpone and grated Parmesan work well. For a dairy-free option, try cashew ricotta or almond-based cheese alternatives.

→ How do I know when it's done baking?

The casserole is ready when the cheese is bubbly and golden brown on top, and you can see the sauce actively bubbling around the edges. A knife inserted in the center should come out hot.

→ Can I add vegetables to this dish?

Absolutely. Sautéed spinach, mushrooms, or zucchini make excellent additions between layers. Just cook and drain any vegetables well to prevent excess moisture.
