1. Step 1: Preheat oven to 375°F (190°C). Lightly grease a 9x9-inch baking dish.

4. Step 4: Stir in steamed cauliflower, 6 slices cooked and crumbled bacon, 2 cups chopped fresh spinach, and 1 cup shredded sharp cheddar cheese until evenly combined.
5. Step 5: Pour the mixture into the prepared baking dish and smooth the top. Sprinkle remaining 1/4 tsp black pepper over the casserole.
6. Step 6: Bake in the preheated oven for 25-30 minutes until the casserole is set, golden on top, and a knife inserted in the center comes out clean. Let cool for 5 minutes before slicing and serving.
