Place the cottage cheese in a blender or food processor and process until the texture is completely smooth and creamy.
Transfer the blended cottage cheese to a medium-sized mixing bowl.
Add the non-fat Greek yogurt and the dry ranch seasoning packet to the bowl and whisk until fully incorporated.
Fold in the shredded cheddar cheese, crumbled bacon bits, and garlic powder using a spatula.
Stir in the chopped green onions, reserving a small amount for garnish if desired.
Cover the bowl and refrigerate for at least 30 minutes to allow the flavors to meld and the dip to firm up.
Serve chilled with fresh vegetables or high-protein crackers.
