Prepare Cauliflower: If using a whole head, wash, remove the core, and chop into florets. Pulse in a food processor until it resembles rice, or use a box grater. Set aside.
Cook Bacon: In a large skillet over medium heat, cook bacon until crispy. Remove bacon slices, drain on paper towels, and crumble once cooled. Reserve 1 tablespoon of bacon fat in the skillet (or add olive oil if preferred).
Sauté Cauliflower: Add the riced cauliflower to the skillet with the reserved bacon fat (or olive oil). Sauté for 5-7 minutes, stirring occasionally, until the cauliflower is tender-crisp.
Combine Ingredients: Remove the skillet from heat. Stir in the unsalted butter, shredded cheddar cheese, and sour cream until the butter and cheese are melted and well combined with the cauliflower.
Season & Serve: Stir in most of the crumbled bacon and half of the sliced green onions. Season generously with salt and freshly ground black pepper to taste. Taste and adjust seasoning as needed.
Garnish & Enjoy: Serve immediately, garnished with the remaining crumbled bacon and green onions. Enjoy this quick and satisfying loaded rice cauliflower!
Notes
For an even richer flavor and creamier texture, substitute half of the sour cream with full-fat cream cheese. Feel free to customize with other keto-friendly toppings like diced jalapeños, chives, or a dash of hot sauce. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated gently on the stovetop or in the microwave.
