This Easy Lasagna is Low Carb, Keto and Vegetarian!

For such an indulgent dish, you might be surprised to find that it’s also compatible with a lot of special dietary requirements. The meatless sauce is vegetarian, packing in the protein thanks to a healthy blend of fresh and aged cheeses.

Since I use eggplant (yum!) rather than traditional pasta, it’s also a low-carb dish that fits a Keto lifestyle. Score! And, don’t be intimidated by using eggplant– it’s actually super easy. Just layer, bake, and go!


Eggplant lasagna is kind of like a cross between Eggplant Parmesan and traditional lasagna. When roasted, eggplant has a mild, savory flavor and texture similar to zucchini. Combined with flavorful Italian tomato sauce and a delicious cheese blend, the result is absolutely drool-worthy. Even picky eaters always come back for more.

  • 2 Large Eggplants: Slice these into ¼ inch long slices – you’ll need about 18 slices.
  • Salt and Olive Oil: For seasoning the eggplant slices.
  • Egg
  • Ricotta, Mozzarella, and Parmesan Cheeses
  • Fresh Garlic
  • Dried Basil and Oregano
  • Prepared Pasta Sauce: I like marinara, but you can use any jarred pasta sauce. If looking to lower them carbs, get a jar of Keto Marinara Pasta Sauce


  1. Roast Eggplant Slices: Preheat oven to 400˚F. Arrange eggplant slices on a parchment-lined baking sheet and sprinkle with salt. When the oven has heated, wipe the salt and moisture away from the eggplant slices with a paper towel. Brush the eggplant slices with olive oil and bake for 15 minutes, or until just tender.
  2. Prepare Cheese Filling: While the eggplant slices are roasting, beat the egg in a large mixing bowl. Add ricotta, mozzarella, parmesan, garlic, herbs, and pepper. Mix well.
  3. Layer Ingredients in Baking Dish: Remove eggplant slices from the oven, and lower the oven temperature to 375˚F. Layer ⅓ of the marinara, ⅓ of the eggplant slices, and ⅓ of the cheese mixture in a baking dish. Repeat 2 more times. Sprinkle with remaining mozzarella and parmesan.
  4. Bake the Lasagna: Cover the dish and bake for 20 minutes. Uncover, and bake 20 minutes longer, or until the lasagna is bubbly and the cheese is golden brown. Let stand 15-20 minutes.
  5. Serve and Enjoy!

  • Choose the best eggplants: Use large, shiny, eggplants with few blemishes and no soft, wrinkled spots.
  • Peel on or off? You can peel the eggplant, or you can leave the peel on. Either way, wash the eggplant well before slicing.
  • Use the best pasta sauce: The pasta sauce is a very important part of this dish, so choose one that has a quality flavor profile, and adjust the salt if necessary before layering.


  • I love serving eggplant lasagna with breadsticks and a garden salad. It’s a classic combination!
  • You can also whip up a light fruit salad using whatever seasonal produce you have, and garnishing it with sweetened whipped cream.


  • To store in the freezer: Wrap leftover portions tightly in plastic wrap and store in plastic food storage bags, pushing out all of the air before sealing. You can also vacuum-seal individual portions.
  • To refrigerate: Cover well and keep for up to 5 days.
  • To reheat lasagna: First thaw in the refrigerator (if frozen). Then reheat in the oven at 350˚F until just heated through.
