Ingredients

Cauliflower (1 head): Choose a firm, fresh head for roasting; this forms the base, replacing pasta with a healthy vegetable alternative.
Olive oil (1 tablespoon): Used to coat the cauliflower ensuring even roasting and enhancing natural flavors.
Heavy cream (½ cup): Adds richness and creates a smooth, velvety texture in the cheese sauce.
Cheddar cheese (4 ounces, freshly shredded): Sharp and flavorful, it melts perfectly to provide a creamy, tangy base.
Colby Jack cheese (4 ounces, freshly shredded): A milder cheese that adds smoothness and subtle sweetness to the sauce.
Cream cheese (2 ounces, room temperature): Incorporates a silky texture and adds tang to enrich the cheese blend.
Paprika (½ tablespoon): Gives a warm, smoky depth to the cheese sauce enhancing overall flavor.
Mustard powder (½ tablespoon): Adds a subtle sharpness that balances the creamy cheeses beautifully.
Salt (to taste): Essential for seasoning, enhances the natural flavors of the cauliflower and cheese.
Black pepper (freshly cracked, to taste): Provides a mild heat and aromatic note that complements the dish.
Fresh chopped parsley: Garnishes the dish with vibrant color and fresh herbal brightness.

Instructions

Preheat and Prepare Cauliflower: Preheat your oven to 450°F and line a baking sheet with parchment paper to prevent sticking. Chop the cauliflower into bite-sized pieces to ensure even roasting and tender texture.
Toss Cauliflower with Oil and Season: Coat the cauliflower pieces evenly with olive oil, then season generously with salt and freshly cracked black pepper. This step adds flavor and helps caramelize the cauliflower during roasting.
Roast Cauliflower to Tenderness: Spread the cauliflower out in a single layer on the baking sheet. Roast for 20 minutes or until tender and lightly browned; roasting enhances the natural sweetness and adds a subtle nuttiness.
Prepare Cheese Sauce: In a medium saucepan over medium heat, whisk together heavy cream, paprika, and mustard powder. Gradually add cheddar, Colby Jack, and cream cheese, stirring frequently until smooth and fully melted, creating a luscious cheese sauce.
Combine Roasted Cauliflower and Cheese Sauce: Add the warm roasted cauliflower to the cheese sauce, stirring gently to coat each piece thoroughly with rich, creamy cheese. This marriage brings together the roasted flavor with the cheesy indulgence.
Garnish and Serve Warm: Finish the dish by sprinkling freshly cracked black pepper and chopped parsley on top for a burst of color and fresh flavor. Serve immediately to enjoy the creamy texture at its best.
