Clean and Cut the Cauliflower: Wash the cauliflower thoroughly and remove the leaves. Cut the cauliflower into medium-sized florets, ensuring they are of equal size to cook evenly.

Blanch the Cauliflower (Optional): If you prefer a softer texture, blanch the cauliflower by bringing a pot of salted water to a boil. Add the cauliflower florets and cook for 3-4 minutes until slightly tender. Drain and set aside. This step can be skipped if you like the cauliflower to have more bite after baking.

Mix the Wet Ingredients: In a large mixing bowl, combine 2 tablespoons of sour cream, 2 tablespoons of mayonnaise, and 1 teaspoon of mustard. Mix well until smooth and creamy.

Add the Eggs: Crack the 2 eggs into the bowl and whisk them into the sour cream and mayonnaise mixture. Continue whisking until the eggs are fully incorporated and the mixture is smooth.

Season the Sauce: Add salt and black pepper to taste. This will bring out the flavors in the dish, so feel free to adjust the seasoning to your liking.

Coat the Cauliflower: Add the blanched (or raw, if preferred) cauliflower florets into the creamy sauce mixture. Gently toss the florets until they are fully coated in the sauce.

Transfer to a Baking Dish: Grease a medium-sized baking dish with oil or butter to prevent sticking. Spread the coated cauliflower evenly in the dish.

Top with Cheese: Sprinkle the grated cheese evenly over the cauliflower. This will create a golden, melted cheese crust on top of the dish.

Bake the Cauliflower: Preheat your oven to 180°C (350°F). Place the baking dish in the oven and bake for 20-25 minutes, or until the cauliflower is tender and the cheese is melted and golden brown.

Check for Doneness: Once the cheese is golden and bubbly, and the cauliflower is tender when pierced with a fork, remove the dish from the oven.

Let it Cool Slightly: Allow the baked cauliflower to cool for 5 minutes before serving. This allows the sauce to set slightly and makes it easier to serve.

Garnish and Serve: You can garnish the dish with fresh herbs like parsley or chives for added color and flavor. Serve the cauliflower as a side dish or main course, accompanied by your favorite protein or salad.
