Step-by-Step Instructions

🥦 Step 1: Prepare the Cauliflower

1. Preheat your oven to 375°F (190°C).
2. Cut the cauliflower into bite-sized florets.
3. Steam or blanch the cauliflower florets for about 5-7 minutes, until they are just tender but still slightly firm.
4. Drain and pat dry with a paper towel to remove excess moisture.

💡 Pro Tip: Make sure the cauliflower is well-dried before baking to avoid a watery dish.

🧀 Step 2: Make the Cheese Sauce

1. In a medium saucepan, melt 2 tablespoons of butter over medium heat.
2. Add the minced garlic and sauté for 1-2 minutes until fragrant.
3. Stir in 1 cup of heavy cream and bring to a simmer.
4. Gradually add 2 cups of shredded cheddar cheese and ½ cup grated Parmesan. Stir continuously until the cheese is completely melted and the sauce is smooth.
5. Add 1 teaspoon Dijon mustard, ½ teaspoon paprika, and ½ teaspoon onion powder, mixing well.
6. Season with salt and pepper to taste.

💡 Pro Tip: For a thicker sauce, let it simmer for a few extra minutes, stirring occasionally.

🥄 Step 3: Assemble the Dish

1. In a baking dish, arrange the steamed cauliflower florets evenly.
2. Pour the cheesy sauce over the cauliflower, making sure to cover it well.
3. Sprinkle an extra ½ cup of cheddar cheese on top for a golden, cheesy crust.

💡 Pro Tip: If you love a crispy topping, you can add a sprinkle of breadcrumbs over the cheese for an added crunch!

🔥 Step 4: Bake to Perfection

1. Place the baking dish in the preheated oven.
2. Bake for 20-25 minutes, or until the top is golden brown and bubbly.
3. For an extra crispy top, broil for the last 2-3 minutes, but watch carefully to avoid burning.

💡 Pro Tip: If the sauce is too thick after baking, you can drizzle a little extra heavy cream over the top before serving for a creamy finish.
