How to Make Cheesy Cauliflower Casserole
Preheat your oven to 350 °F (175 °C) and prepare a 9 9-inch baking dish by greasing it lightly with butter to prevent sticking, ensuring a beautiful finish for your casserole.
Blanch the frozen cauliflower florets in a pot of boiling salted water for about 5 minutes. This helps soften them slightly; then drain and set aside in the prepared baking dish.
Melt the butter in a pan over medium-low heat, and then stir in the flour to create a roux. Cook until bubbly and a light golden color, about 1-2 minutes, to develop a rich flavor.
Gradually add the sour cream and one-third of the milk, whisking until well combined and smooth; then slowly stir in the remaining milk and heavy cream. Bring to a gentle boil while constantly whisking, cooking for about 3-4 minutes until the mixture thickens.
Season the sauce by stirring in pepper and grated Parmesan cheese until melted. Taste and add salt as needed for that perfect flavor profile.
Pour the luscious cheese sauce directly over the blanched cauliflower, spreading it evenly to ensure every bite is cheesy goodness. Top with the grated gouda for that irresistible melty crust.
Bake the casserole in the preheated oven for 20-30 minutes, or until the cheese is bubbly and golden brown on top. Serve hot, and watch it disappear!
Optional: Garnish with fresh parsley for a pop of color and flavor!
