Prepare the Cauliflower & Bacon: Rice the cauliflower by grating it or pulsing it in a food processor.
In a large skillet over medium heat, cook the chopped bacon until crispy, about 10-12 minutes. Use a slotted spoon to move the bacon to a paper towel-lined plate, reserving 2 tablespoons (30 ml / 1 fl oz) of the grease.
Sauté the Cauliflower: Return the skillet to medium heat with the reserved bacon grease.
Add the riced cauliflower, season with salt and pepper, and sauté for 5-7 minutes until tender-crisp. Avoid overcooking to prevent it from becoming mushy.
Get it Cheesy: Reduce the heat to low.
Stir in the shredded cheddar, three-quarters of the crispy bacon, and half of the chives.
Continue stirring until the cheese is fully melted and everything is beautifully combined.
Serve and Garnish: Transfer the loaded cauliflower to a serving dish.
Top with the remaining bacon and chives.
Serve immediately, with a dollop of sour cream for the full loaded potato experience!
Don't Overcook the Cauliflower: The key to the perfect texture is to sauté the cauliflower rice until it's just tender-crisp. Overcooking will release too much water and make it soggy.
