• 2 tbsp olive oil
• 1/4 tsp sea salt
• 1/4 tsp black pepper

Meat Sauce

• 1 tsp olive oil
• 2 cloves garlic, minced
• 1.5 lb ground beef
• 1 tsp sea salt
• 1/2 tsp black pepper
• 1.5 cups marinara sauce (sugar-free for keto)

• 1/2 cup grated parmesan cheese

How to Make Keto Eggplant Lasagna (Step-by-Step)

1. Roast the Eggplant

• Preheat oven to 400°F (204°C). Line and grease a large baking sheet.
• Arrange eggplant slices in a single layer. Brush both sides with olive oil and sprinkle with salt and pepper.
• Roast for 15–25 minutes until soft. Remove and set aside (keep oven on).

2. Make the Meat Sauce

• In a skillet, heat olive oil over medium heat.
• Sauté garlic for 1 minute until fragrant.
• Add ground beef. Season with salt and pepper. Cook for ~10 minutes, breaking it up as it browns.
• Stir in marinara sauce and Italian seasoning. Simmer for 10 minutes.

3. Mix the Cheese Filling

• In a bowl, combine ricotta, parmesan, and egg. Stir until smooth.

4. Assemble the Lasagna

• In a greased baking dish, layer:
  1. Roasted eggplant slices (4–6 per layer)
  2. Half of the meat sauce
  3. Half of the ricotta mixture
  4. Mozzarella cheese
  5. Repeat layers and top with final layer of mozzarella

5. Bake and Enjoy

• Bake at 400°F for 10–15 minutes until cheese is bubbly and golden.

Let it sit for 5–10 minutes before slicing for clean layers!

Tips for the Best Texture

• Slice eggplant evenly so it cooks at the same rate
• Roast, don’t fry – baking reduces moisture for less sogginess
• Use a thick marinara – thinner sauces may make it watery
• Let it rest before slicing – this keeps layers intact

Variations to Try

• Add sautéed mushrooms or zucchini to the meat sauce
• Use Italian sausage instead of ground beef
• Swap ricotta for cottage cheese for a lighter option
• Make it vegetarian with spinach and mushrooms instead of meat
• Use white sauce for a creamy variation

Storage & Make-Ahead

• Fridge: Store in an airtight container up to 4 days
• Freezer: Freeze individual portions for easy reheating
• Reheat: Microwave or bake until hot throughout
