In mixer, combine cream cheese, sour cream, mayo, rotel, horseradish, onion, bacon grease, salt & pepper.
Mix in cheese and bacon by hand.
Spread in dish to serve, and garnish with a few extra bacon pieces, cheese and scallions if desired.
Serve with tortilla chips, crackers or our favorite Frito Scoop corn chips (processed I know...but it's our favorite way to eat this dip & we only make it a couple times a year!)
Refrigerate, and will keep all week...but probably won't last that long.
Notes
*I buy hormone-free nitrate and nitrite-free bacon.
Can mix all by hand instead of using a mixer.
