This Caprese casserole has seriously become one of our favorite Keto vegetarian casserole recipes. It is simple to make and tastes amazing.

How do you make this Keto caprese casserole?

Start by baking the seasoned cauliflower florets until they are slightly charred. In a saucepan, make the creamy tomato sauce and season with red chili flakes, salt, and black pepper. Then, stir in the baked cauliflower, shredded mozzarella cheese, chopped tomatoes, and fresh basil into the creamy tomato mixture.

How do you store this Keto vegetarian caprese casserole?

This casserole dish can be prepared ahead of time and stored to be enjoyed later. To store, allow the casserole to cool down completely. Then, wrap the casserole dish with aluminum foil (do this in 2 layers to avoid any leakage when storing). Transfer the casserole to the refrigerator for 3-5 days. Alternatively, once the casserole has cooled down, scoop it out and transfer it to an airtight container, and store it in the refrigerator. Reheat the casserole in a preheated oven in the casserole dish or in the microwave for about 30 seconds in the airtight container.

This caprese casserole can be customized in a couple of ways. For vegetable lovers, feel free to add in as many low-carb vegetables as you like. Vegetables that would work well in this casserole include eggplant, zucchini, carrots, mushrooms, and peppers. For a protein source, add in some crumbled tofu to make it more filling. Adding different types of cheeses can also enhance the flavors of this dish. Once baked, sprinkle some crumbly cheese, such as cottage cheese or freshly grated parmesan cheese on top before serving.

        You can try coconut cream. It has a slight coconut taste —I like the one from Trader Joe’s— but with all the other ingredients here it may not be noticeable.

        You can use coconut milk or a combination of cream cheese and almond milk,
