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

How to Make It

Step 1

Preheat the oven to 450F/220C. Grease the casserole dish with olive oil and line a baking sheet with parchment paper. Cut the cauliflower into florets and arrange them in a single layer on the baking sheet. Drizzle the 2 tbsp olive oil, and season with ¼ tsp salt and ¼ tsp black pepper. Bake for 30 minutes until the cauliflower is slightly charred.

Step 2

Shred the mozzarella cheese, chop the basil, and slice the tomatoes. Add the tomato sauce and paste in a saucepan over low heat. Once heated, add the heavy cream, red chili flakes, ¼ tsp salt, and ¼ tsp black pepper. Stir to combine and remove from the heat.

Step 3

Add baked cauliflower, half of the mozzarella cheese, half of the tomatoes, and ¼ cup of chopped basil into the tomato mixture. Stir to coat everything together evenly, then pour the mixture into the casserole dish. Spread the mixture using a spatula to create an even layer.

Step 4

Top with the remaining mozzarella cheese and chopped tomatoes. Lower the oven temperature to 350F/180C before putting the casserole into the oven. Bake for 30 minutes until the cheese is completely melted and the tomatoes slightly wilted.

Step 5

To get a golden color on the cheese, turn on the broiler setting and broil for about 2 minutes until the cheese is bubbly and has got a golden color. Remove the casserole from the oven and allow it to cool down slightly for 5 minutes.

Step 6

Garnish with 1 tbsp chopped basil. Serve warm with a wedge of lemon. Store leftovers in the refrigerator in an airtight container for 3-5 days.
