Cooking with eggplant can be a little bit cumbersome but we have perfected it.

If you’ve tried our air fryer eggplant, eggplant pizza, or eggplant parmesan before, you’ll no doubt love this eggplant lasagna. It’s got all the best parts of a classic lasagna but with a nutritional boost!

Why this recipe works

  • Healthy AND low carb. Packed with slices of eggplant, a delicious meat sauce, and even some hidden spinach, it’s pack with protein, fiber, and healthy fats. Swapping out lasagna noodles for eggplant keeps the texture and bulk WITHOUT sacrificing on taste.
  • Simple ingredients. Many keto recipes include some hard-to-find ingredients. This lasagna uses simple, fresh, and easy-to-find ingredients. 
  • No watery lasagna. Salting and roasting the eggplant prior to baking the lasagna will guarantee no watery lasagna ever. 
  • Delicious way to jazz up eggplant. Just like sauteed eggplant or rollatini, this takes eggplant to another level.

The secret to the perfect eggplant lasagna is to roast the eggplant slices before assembling them all together. This ensures perfectly soft eggplant and the overall lasagna to NEVER be watery.

Ingredients needed

This recipe calls for simple and affordable ingredients that can be found at any mainstream grocery store. Here is what you’ll need:

For the eggplant lasagna

  • Eggplant– Choose an eggplant that is firm on the outside with minimal bruising. The softer the eggplant is, the harder it will be for the lasagna to hold together. 
  • Salt– Sprinkle over the eggplant to draw out excess moisture. 
  • Olive oil– A flavorful oil to cook the meat sauce in. 
  • Ground beef– I used lean ground beef, but you can use slightly fattier cuts, like 80/20 ground beef (80% lean, 20% fat). 
  • Marinara sauce– Skip the expensive store-bought variety and make your own spaghetti sauce (which works perfectly for this!). 
  • Italian seasonings– Necessary flavors for any good lasagna or meat sauce. 

For the cheese filling

  • Ricotta cheese– Aim to use good quality and full-fat ricotta cheese. Alternatively, you can use full-fat cottage cheese. 
  • Cheddar cheese– Or any fully flavored shredded cheese of choice. 
  • Frozen spinach– Thawed and with its excess liquid squeezed out. 
  • Egg– To thicken the filling. 
  • Mozzarella cheese– To layer the lasagna and cover the top of the lasagna with. 
  • Fresh basil– To serve.

Can I make this lasagna in advance? 

This lasagna is one you can definitely make ahead of if you like. You can do so a few days in advance (and refrigerate it) or a few months in advance (and freeze it). 

  • Refrigerate then bake– Cover the uncooked lasagna in tin foil and place the dish in the refrigerator for up to 3 days. Remove the lasagna from the refrigerator 30 minutes before baking it. Using a paper towel, mop up any excess liquid around the sides. 
  • Freeze then bake– Wrap the uncooked lasagna in saran wrap, followed by tin foil, then place it in the freezer for up to 2 months. The night before baking, place the frozen lasagna in the refrigerator to thaw out. Let the uncooked lasagna sit at room temperature for 30 minutes before cooking it. 

Tips to make the best recipe

  • You must salt and roast the eggplant before assembling the lasagna. It drains out extra liquid and helps ensure this lasagna is NOT watery. You also risk the eggplant being gummy and dense. 
  • Don’t worry if you don’t have enough eggplant to form multiple layers. You can simply increase the meat sauce, cheese filling, and mozzarella cheese on top.
  • If you’d like a vegetarian eggplant lasagna, simply omit the ground beef and layer up with the marinara sauce. 

Storage instructions

  • To store: Eggplant lasagna can be stored in the refrigerator, covered, for up to 5 days. 
  • To freeze: Place portions of the lasagna in a shallow container and store in the freezer for up to 6 months. 
  • Reheating: Reheat the lasagna in a preheated oven at 180C/350F for 10 minutes.

  1. The recipe ingredients say eggplant cut in 1/4 in slices. The instructions say to cut them in 1/2 slices. Can you clarify? Thanks!
