What Is Moussaka?

The king of Greek comfort food is moussaka. It is a rich casserole with layers of crispy but buttery potatoes, eggplants, a ground beef sauce, and velvety thick bechamel sauce.

Moussaka is a treat to eat and has never been on the list of low-carb foods. Until now, that is!

Ingredients

This keto moussaka recipe has layers of sliced eggplant and yellow squash.

The traditional hearty ground beef ragù sauce has added cubed pancetta for more depth of flavor. There are no tomatoes or tomato paste in the meat sauce to keep the carb count low.

Ingredients for keto moussaka. Ground beef, eggplants, yellow squash, a bowl with cubed pancetta, a bowl with heavy cream, a bowl with cheese, a cup of broth, a cup of cream cheese and a small cutting board with spices, all on a butcher block.

The bechamel is replaced with a cheese sauce, simple to make and very similar in taste. Heavy cream is the base, with nutty grated gruyere cheese, cream cheese for smoothness, ground nutmeg for warmth, and minced garlic, because everything is better with it in it ;-).

This recipe yields 10 grams of net carbs per serving*.

Helpful Q&A

Is moussaka healthy?

Traditional moussaka - a combination of potatoes, eggplants, ground beef, and bechamel is definitely a rich, highly caloric dish. Having said that, a piece of moussaka cooked from scratch with fresh, good quality ingredients and extra virgin olive oil is a much healthier choice than a sandwich with highly processed white bread, deli meat, and dubious cheese.
Additionally, this keto moussaka recipe has 10 grams of net carbs*, has a low glycemic index, and great ingredients. Paired with a big green salad, it is a perfectly healthy meal compliant with a low-carb lifestyle.

Do I need to salt the eggplant first?

It depends. Eggplants can be quite bitter, and salting helps cut the bitterness. The salt hides the bitter taste. I find it brings out the sweetness of the vegetable. Also, salt draws out excess moisture and makes the texture of the eggplant silky and creamy. If you are sure your eggplants are super fresh, you can probably skip the salt.
