Low Carb Zucchini Casserole

We LOVE keto zucchini recipes and this healthy zucchini casserole is one of our favorites.

This cheesy keto zucchini casserole is crispy on the outside, and creamy and cheesy on the inside. Naturally, zucchini casseroles can be made with any type of cheese as long as it’s combined with a liquid element.

In this casserole we used sour cream, feta and mozzarella cheese. The sour cream provides a great texture and tang while the feta cheese turns rich and buttery in the oven. Mozzarella was added as it pairs well with basically anything and melts really well into this mouth-watering casserole dish.

How To Make Baked Zucchini Casserole

Step 1

Preheat your oven to 425 degrees Fahrenheit (220 degrees Celsius) and grease a baking dish with butter.

Step 2

Cut the zucchini into ¼ inch thick slices, place them in a strainer and season them with salt. Set aside while you follow the next steps as the salt extracts excess water.

Step 3

Roughly slice the onion and heat butter in a saucepan over a medium high heat. Sauté the onion for 5 minutes, then add the minced garlic and season with salt and pepper. Cook for another minute until fragrant and then pour in the sour cream.

Simmer for another 2-3 minutes over medium heat and then turn off the heat. Add the feta and mozzarella cheese and stir them into the mixture.

Step 4

Pat the zucchini slices dry with a paper towel or cloth. Lay the zucchini slices into the greased baking dish.

Next, pour over the cheesy sauce mixture.

Step 5

Bake the zucchini casserole for around 15 to 20 minutes in the preheated oven until golden brown. Slice and serve hot directly from the oven.
