Ingredients
  

Beef Layer
  • 1.5 lbs Ground Beef (80/20) Browned into crumbles
  • 1 tbsp Olive Oil For searing
  • 1 tsp Garlic Powder
  • 1 tsp Onion Powder
  • 1/4 cup Heavy Cream For binding
Vegetable & Topping
  • 1 large head Cauliflower Cut into large florets and steamed
  • 2.5 cups Sharp Yellow Cheddar Cheese Shredded for melting
  • 1/2 cup Green Scallions Freshly chopped for garnish

Equipment

  • 1 Square White Ceramic Baking Dish (9x9) Essential for the layered presentation.
  • 1 Large Cast-Iron Skillet Used for browning the ground beef.
  • 1 Steamer Basket To ensure cauliflower is tender but not watery.

Method
 

Prepare the Beef Foundation
  1. Heat oil in a skillet over medium-high heat. Add ground beef and cook until browned crumbles form. Drain excess fat.
  2. Stir in garlic powder, onion powder, salt, pepper, and heavy cream. Spread evenly into the bottom of the white ceramic dish.
Steam and Layer
  1. Steam cauliflower florets for 5-7 minutes until tender but firm. Drain thoroughly.
  2. Arrange the tender white cauliflower florets in a thick layer over the beef foundation.
Bake and Garnish
  1. Top the casserole with shredded cheddar cheese, covering the cauliflower completely.
  2. Bake at 400°F (200°C) for 15-20 minutes. Broil for 2-3 minutes until the cheese shows golden-brown toasted spots.
  3. Let rest for 5 minutes, then top with a generous sprinkle of freshly chopped green scallions before serving.

Notes

Tip 1. Pat steamed cauliflower dry to prevent a watery casserole.
Tip 2. Use sharp cheddar for a more complex flavor profile.
