Equipment

  • 2 large sheet pans
  • cutting board
  • chef's knife
  • medium saute pan or skillet
Start Cooking

Ingredients
 

  • 1 1/2 pounds eggplant
  • 3 tbsp olive oil (divided use)
  • 2 cloves garlic, sliced
  • 1 pound lean ground beef
  • 1 tsp Better Than Bouillon Beef Base
  • 1/2 tsp dried basil
  • 1 1/2 cups Keto Tomato Sauce (or your favorite low carb Marinara)
  • 15 oz whole milk ricotta cheese
  • 1 large egg
  • 3 cups mozzarella cheese (divided use)
  • 1/2 cup grated Parmesan cheese

Instructions
 

Eggplant (Preheat oven to 400 F)

  • Trim a thin slice from the bottom and remove the top, then stand the eggplant upright and cut it lengthwise into 8 slices about 1/4 inch thick.
  • Coat two large sheet pans with 1 tablespoon oil each, arrange 4 eggplant slices on each pan, and bake for 6-8 minutes per side before flipping and baking the second side for another 6-8 minutes.

Meat Sauce

  • While the eggplant cooks, warm the remaining 1 tablespoon olive oil in a medium saute pan over medium heat and cook the sliced garlic until slightly softened.
  • Add the ground beef and cook it through, breaking it into small crumbles as it browns.
  • Stir in 1 cup of the marinara, the beef base, and the dried basil, then simmer until the sauce thickens and cool it slightly before layering.

Ricotta Cheese

  • Place the ricotta in a large bowl, mix in the egg with a fork, then stir in 1 1/2 cups mozzarella and 1/3 cup Parmesan.

Layer

  • Spread 1/2 cup sauce across the bottom of a 9x13 inch lasagna pan, then add 4 eggplant slices, half of the ricotta mixture, and half of the meat sauce.
  • Repeat the layers once more and finish with the remaining mozzarella and Parmesan over the top.

Bake (Preheat oven to 375 F)

  • Lay a piece of parchment over the lasagna, cover tightly with foil, and bake at 375 F for 30 minutes.
  • Remove the foil and bake 10 minutes more, then rest the lasagna for 10-15 minutes before cutting into 8 pieces.

Slow Cooker

  • Coat the slow cooker insert with non-stick cooking spray and layer the prepared ingredients in the same order used for the oven version.
  • Cover and cook on high for 2-3 hours, until a knife slides in with little resistance, then turn off the heat and let it sit covered for 30 minutes to 1 hour before slicing.

Notes

Make-Ahead Tip: You can assemble the lasagna up to 24 hours in advance. Cover and refrigerate, then add an extra 5-10 minutes to the covered baking time.
Storage: Store cooled leftovers in a covered container in the refrigerator for 3 to 4 days.
Texture Tip: To prevent a watery result, make sure to roast the eggplant until the surface is dry, use a thick meat sauce, and drain any excess grease from the beef before layering.
Ricotta Filling: Don't skip the egg in the ricotta mixture. It acts as a binder, helping the cheese layer set properly instead of becoming loose or grainy.
