Why you’ll love this easy eggplant pasta bake

  • Hearty vegetarian meal. This baked eggplant casserole is so comforting, with chunks of eggplant throughout a zesty marinara sauce, loaded with pasta, and covered in cheese. It’s so filling and delicious!
  • Flavor and Texture. Eggplant’s unique and subtle flavor makes it a perfect ingredient for absorbing other flavors. Its tenderness and texture are enhanced after roasting and then cooked in a casserole, making it an excellent addition to any dish.
  • Easy to make. After roasting the eggplant, which only takes about 15 minutes, everything is tossed together in a baking dish and baked until the cheese is golden brown and melty.

ingredients to make the recipe

  • Eggplants: The eggplants are chopped into pieces and roasted to enhance the flavor and get rid of any excess moisture.
  • Oil: To roast the vegetables. We like to use olive oil, but vegetable or canola will work well.
  • Seasonings: Salt, black pepper, crushed red pepper and fresh basil leaves.
  • Onion and garlic: No Italian style dish is complete without onion and garlic! They add a nice base level of flavor.
  • Pasta: This pasta casserole is great with rigatoni, a large tubular pasta. Other pasta shapes like penne of fusilli will work well too.
  • Marinara sauce: This is where this yummy pasta bake gets it’s rich tomato flavor. You can use your favorite store bought, or make your own marinara instead.
  • Cheese: We use parmesan and mozzarella for a cheesy pasta dish. You can use other shredded cheeses like mozzarella or jack if that’s what you have to hand.

Total Time 40 minutes



  • 2 medium eggplants cut into 1-inch pieces
  • ¼ cup olive oil
  • 1 teaspoon salt plus more to taste
  • Black pepper to taste
  • 1 small yellow onion chopped
  • 4 garlic cloves minced
  • ¼ teaspoon crushed red pepper
  • 1 pound rigatoni
  • 1 28-ounce jar marinara
  • 1 cup freshly grated Parmesan plus more for serving
  • 3 cups shredded mozzarella cheese divided
  • 1 cup fresh basil leaves torn, plus additional for serving


  • Preheat oven to 425°F. Line a baking sheet with parchment paper.
  • Place the eggplant, olive oil, 1 teaspoon salt, and black pepper in the prepared sheet pan. Roast for 20 minutes, then flip halfway through, add the onions, garlic, crushed red pepper and return to the oven until the eggplant is golden brown and caramelized, 15 more minutes.
  • Meanwhile, bring a large pot of heavily salted water to a boil and cook pasta until barely al dente. Reserve 1 ½ cups pasta cooking water, then drain and rinse pasta under cold water.
  • Transfer the pasta to a 9×13 baking dish. Add marinara and stir as much reserved pasta cooking water as needed until the sauce is glossy.
  • When the eggplant is done cooking, transfer it on top of the pasta. Fold in the Parmesan cheese, 1 cup mozzarella and 1 cup basil. Top with remaining 2 cups mozzarella.
  • Lower the oven temperature to 375°F and bake until the sauce is bubbling on the sides and the cheese is melted, about 25 minutes. Top with more grated parmesan and torn fresh basil to serve.


Storage: Store leftovers in an airtight container and keep in the fridge for up to 4 days.

  1. Step 2 is confusing. I am interpreting roast for 20 minutes the eggplant only. It sounds like at the 10 minute mark you flip. Then after this total of 20minutes is over, add onions and peppers for another 15 minutes. Total oven time is 35 minutes. This also does not align with the cook and prep time estimates.

    1. Yup, you are interpreting it correctly because the eggplant just needs more time as compared to the onions and peppers. I will update my time estimates though, to match this. Sorry for the incorrect calculation there!

  2. Thankyou for this recipe, helped me learn I love roasted eggplant over sautéed but also the flavours were perfect.
    Partner also loved it, will be making again.

  3. This is sooo good. Have made it 3x now. Used eggplant from my garden, added peppers, extra garlic and about 1/2 the cheese. Husband is a huge fan. Thanks for the great recipe

  4. This is such a teriffic, flexible, comforting dish. We like to boost the veggies when we have extra on hand (zucchini and bell peppers work well, added with the onions and garlic halfway through roasting). We sometimes sub whole wheat pasta, which we find works best in casserole-type dishes rather than on its own. The original had a little too much cheese for us, so now we reduce to 2 cups. Delicious and indulgent as written, or easy to tweak with modifications. Thank you for another great recipe!

    1. You could, or you could store it in an airtight container after cooking and keep in the fridge for up to 4 days.
