Line a half sheet jelly roll pan or a cookie sheet with foil. Place tator tots in a single layer on sheet. Bake for 25-28 minutes per package instructions until crispy.
Remove from oven. Sprinkle sour cream & ranch mixture on. Sprinkle cheese on. Sprinkle bacon bits on.
Return to oven for 3-5 minutes until cheese melts.
Enjoy!
Notes
You don't have to mix ranch with the sour cream, but it adds a nice flavor. It is totally optional though. My family isn't a big fan of green onions, so I leave those off. I just sprinkle some parsley on top for a nice color.
