Equipment

  • 1 9x13-inch baking dish greased
  • 1 large saucepan
  • 1 Mixing Bowl

Ingredients
  

Main Ingredients

  • 1 head cauliflower cut into florets
  • 2 cups cooked long-grain rice
  • 2 cups sharp cheddar cheese grated
  • 2 tbsp unsalted butter
  • 2 tbsp all-purpose flour
  • 2 cups milk
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1/2 tsp paprika
  • Salt and pepper to taste

Optional Topping

  • 1/2 cup breadcrumbs
  • 1 tbsp melted butter

Instructions
 

Preparation

  • Preheat the oven to 375°F. Cut the cauliflower into small florets. Bring a pot of salted water to a boil, blanch the cauliflower for 3-4 minutes until just tender. Drain and set aside.
  • In a large saucepan, melt butter over medium heat. Add flour and whisk to form a roux. Slowly add milk, whisking continuously until the sauce thickens. Stir in garlic powder, onion powder, paprika, salt, and pepper.
  • In a large mixing bowl, combine cooked rice, blanched cauliflower, and half of the grated cheddar cheese. Pour the cheese sauce over the mixture and stir until well combined.
  • Transfer the mixture to a greased 9x13-inch baking dish, spreading it evenly. Top with remaining cheddar cheese and breadcrumbs mixed with melted butter if desired.

Serving

  • Bake the casserole in the preheated oven for 25-30 minutes or until the cheese is bubbly and golden brown. Let it cool slightly before serving.

Storage

  • Allow the casserole to cool completely. Store in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.

Notes

Ingredient Substitutions: Substitute cheddar with Monterey Jack for a milder flavor.
How to Serve: Pair with a green salad or roasted vegetables.
Storage & Freshness: Store leftovers in an airtight container for up to 3 days.
Make-Ahead Tips: Assemble the casserole a day ahead and bake when ready to serve.
