Add your sour cream and ranch dressing mix to a bowl. Mix to combine.
Once the ranch mix has fully mixed with the sour cream, add in your cheddar cheese. Mix until it's fully combined.
Add in your bacon and fold to incorporate. Don't be too rough because you don't want the bacon falling apart completely. You want to keep nice little crispy chunks in there.
Serve it with your favorite chips, crackers, or vegetables! I like to sprinkle a little extra bacon and cheese on top.
