How to Make Baked Cauliflower and Cheese Casserole
Preheat oven: Set your oven to 375 °F (190 °C). This will give your casserole the perfect golden finish. Grease a medium baking dish to ensure nothing sticks!
Boil cauliflower: Bring a pot of salted water to a boil and add your cauliflower florets. Cook for about 5 minutes until tender, then drain well to prevent excess water from making your casserole soggy.
Prepare roux: Melt 2 tablespoons of butter in a saucepan over medium heat. Whisk in 2 tablespoons of all-purpose flour, stirring for 1 2 minutes until it forms a roux that s smooth and slightly bubbly.
Make cheese sauce: Gradually whisk in 2 cups of milk, cooking until the mixture thickens. Once thickened, stir in 1 teaspoon of Dijon mustard, 1 teaspoon of garlic powder, 1 teaspoon of onion powder, and season with salt and pepper to your taste.
Melt cheeses: Add 1 ½ cups of shredded sharp cheddar cheese and 1 cup of shredded mozzarella to the sauce, stirring until perfectly melted and creamy. This sauce is the heart of your casserole!
Combine cauliflower and sauce: Gently fold the cooked cauliflower into the cheese sauce, making sure every piece is luxuriously coated.
Transfer to baking dish: Carefully pour the cheesy cauliflower mixture into your greased baking dish. Sprinkle the remaining cheddar, ¼ cup grated Parmesan, and if desired, breadcrumbs and a dusting of paprika on top for added crunch.
Bake: Place the baking dish in the oven and bake uncovered for 25 30 minutes or until it s bubbling and golden brown on top. The aroma will be absolutely tempting!
Garnish and serve: Once baked, let it cool for a few minutes, then garnish with fresh chopped parsley for a touch of color and freshness before serving.

Baked Cauliflower and Cheese Casserole Recipe FAQs
What type of cauliflower should I use for the casserole?
Absolutely! A large head of fresh cauliflower works best for this dish. Look for florets that are firm and free of dark spots. If you find any discoloration or limpness, it s best to skip them, as they won t hold up well in the casserole or provide the same delightful texture.
How should I store leftovers of the baked casserole?
Very simply! Once cooled, store your Baked Cauliflower and Cheese Casserole in an airtight container in the fridge. It will stay fresh for up to 4 days. When ready to enjoy, just reheat in the oven or microwave until warmed through.
Can I freeze the casserole before baking?
Certainly! To freeze, assemble the casserole but don t bake it. Cover it tightly with plastic wrap and then foil, and pop it in the freezer for up to 2 months. When ready to bake, simply remove it from the freezer, uncover, and bake directly from frozen at 375 °F (190 °C) for about 45 minutes. Keep an eye on it to ensure it cooks evenly!
Why is my cheese sauce not smooth?
Oh no, that can be frustrating! If your cheese sauce turns out lumpy, it might be due to adding the cheese too quickly or not whisking enough while incorporating the milk. Be sure to gradually whisk in the milk and continuously stir until the sauce thickens before adding cheese. If it still doesn t come together, an immersion blender can be your best friend for achieving that silky consistency.
Is this casserole suitable for gluten-free diets?
Absolutely! You can easily make this delicious Baked Cauliflower and Cheese Casserole gluten-free by substituting all-purpose flour with cornstarch or gluten-free flour. Just follow the same steps in preparing the roux, but be sure to whisk thoroughly to achieve that desired thickness without any lumps. Enjoy the comfort without the carbs!
