Here’s my go-to keto eggplant parmesan recipe, with crispy coated eggplant slices, layers of melty mozzarella and parmesan cheese, and a rich tomato sauce that keeps the carbs low without sacrificing flavor.
This keto-friendly version has become a regular at our dinner table, and even my non-keto friends ask for the recipe. I often make a double batch because the leftovers heat up so well for lunch the next day. Who doesn’t love Italian food that fits their diet, right?
Why You’ll Love This Eggplant Parmesan
- Keto-friendly comfort food – Using almond flour instead of breadcrumbs keeps this classic Italian dish low-carb while maintaining that satisfying crispy coating you crave.
- Simple ingredients – You only need a handful of basic ingredients that are easy to find at any grocery store – perfect for when you want something special without hunting down fancy items.
- Health-conscious – This lighter version gives you all the cheesy, savory flavors of traditional eggplant parmesan with fewer carbs and calories.
- Vegetarian-friendly – It’s a filling main dish that satisfies both vegetarians and meat-eaters alike, proving that meatless meals can be both hearty and delicious.
What Kind of Eggplant Should I Use?
For eggplant parmesan, the classic Italian or Globe eggplant is your best bet – it’s the large, dark purple one you’ll find in most grocery stores. When picking your eggplant, look for one that’s heavy for its size with smooth, shiny skin and no soft spots. A fresh eggplant should feel firm when you give it a gentle squeeze. The smaller ones tend to be less bitter and have fewer seeds, so if you see a medium-sized one that’s about 1 pound, that’s perfect for this recipe. To help reduce any bitterness and improve the texture, you can slice your eggplant and salt it for about 30 minutes before cooking – this draws out excess moisture and makes the final dish even better.
Options for Substitutions
Need to make some swaps? Here are some keto-friendly substitution options that’ll keep your dish low-carb:
- Almond flour: You can swap almond flour with crushed pork rinds, coconut flour (use only 1/2 cup as it’s more absorbent), or ground sunflower seeds if you have a nut allergy.
- Eggplant: While eggplant is key to this classic dish, you could use zucchini slices if you’re not an eggplant fan. Just be sure to salt and drain them well like you would eggplant.
- Mozzarella cheese: Any melting cheese works here – try provolone, low-moisture mozzarella, or a mix of Italian cheeses. Just check the carb content to keep it keto-friendly.
- Egg: For egg-free coating, try heavy cream or a mixture of heavy cream and water. The coating might not stick quite as well, but it’ll still work.
- Pasta sauce: Make sure to use a sugar-free marinara sauce. You can also use crushed tomatoes mixed with Italian seasonings – just check the label for added sugars.
Watch Out for These Mistakes While Baking
The biggest challenge when making keto eggplant parmesan is dealing with excess moisture – skipping the crucial step of salting your eggplant slices and letting them sit for 30 minutes can lead to a soggy, waterlogged dish instead of the crispy texture you’re after. Another common mistake is cutting the eggplant too thick – aim for 1/4 inch slices to ensure they cook evenly and get properly crispy when baked. To achieve the best coating, don’t skip drying the eggplant thoroughly after salting, and make sure to dip each slice in egg first, then almond flour, pressing gently to help the coating stick. For the crispiest results, arrange your eggplant slices in a single layer on the baking sheet and avoid overcrowding, which can trap steam and prevent proper browning.
What to Serve With Keto Eggplant Parmesan?
This low-carb take on eggplant parm pairs really well with simple sides that keep your meal keto-friendly. A big bowl of zucchini noodles tossed with olive oil and garlic makes an excellent base for the eggplant, catching all those tasty sauce drippings. For some green veggies on the side, try serving it with roasted broccoli, a fresh arugula salad dressed with lemon and olive oil, or some sautéed spinach with garlic. If you’re extra hungry, you could add some Italian-seasoned chicken breast or a side of meatballs made with ground turkey or beef to round out your meal.
Storage Instructions
Keep Fresh: Your keto eggplant parmesan will stay good in the fridge for up to 4 days when stored in an airtight container. The almond flour coating might soften a bit, but the flavors actually get even better as they meld together!
Freeze: Want to make a bigger batch? You can freeze this dish for up to 3 months! Just wrap it well in foil and place it in a freezer-safe container. I recommend freezing it before adding the final cheese topping for best results.
Reheat: To get that nice crispy texture back, pop it in the oven at 350°F for about 15-20 minutes. If reheating from frozen, thaw overnight in the fridge first. For best results, use an air fryer for 5-7 minutes – it brings back that wonderful crispy coating!

Ingredients
- Nonstick spray (avocado oil recommended)
- 1 large eggplant (approximately 1 pound)
- 1/2 teaspoon sea salt
- 1/4 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1 large egg
- 1 1/2 cups almond flour
- 1/2 cup pasta sauce
- 1 cup mozzarella cheese, shredded
- 1/4 cup grated parmesan cheese
- 2 tablespoons chopped parsley for garnish
Step 1: Prepare for Baking
Start by preheating your oven to 425°F (218°C).
Line a rimmed baking sheet with high-heat-resistant parchment paper and lightly spray it with cooking spray to prevent sticking.
Step 2: Slice and Season the Eggplant
Slice the unpeeled eggplant into 1/2-inch rounds, discarding the ends.
Lay the eggplant slices out and season them liberally with salt, pepper, and a sprinkle of garlic powder to taste.
Step 3: Set Up Breading Stations
In a shallow bowl, whisk together one egg with a tablespoon of water to create an egg wash.
In a separate shallow bowl, place the almond meal.
This setup will be used for coating the eggplant slices.
Step 4: Coat the Eggplant Slices
Dip each slice of eggplant into the egg wash, ensuring it is fully coated, then dredge it in the almond meal, pressing gently to adhere.
Arrange the coated eggplant slices evenly on the prepared baking sheet.
Spray the tops lightly with cooking spray.
Step 5: Bake the Eggplant
Bake the eggplant slices in the preheated oven until they are tender and golden brown, about 20 minutes per side.
Use a spatula to carefully flip them halfway through the baking time.
Step 6: Add Sauce and Cheese
Without turning off the oven, remove the baking sheet from the oven.
Top each eggplant slice with a generous spoonful of marinara sauce, followed by mozzarella and parmesan cheese.
Return the baking sheet to the oven and bake for an additional 5 minutes, or until the cheese melts and is bubbly.
Step 7: Garnish and Serve
Once the cheese is perfectly melted, remove the baking sheet from the oven.
Allow the eggplant to cool slightly before garnishing with chopped parsley for a fresh touch.
Serve the cheesy, saucy eggplant slices warm and enjoy!
