If your mashed potatoes are too soupy, put them over medium/low heat with the top off and let them cook for about 10 minutes. Stir potatoes often so the bottom doesn't burn.

That's one reason I always keep instant mashed potato flakes in my pantry. If I accidentally put too much milk in my potatoes I just add some flakes until they are the right consistency!
I usually add some instant mashed potato flakes if mine are runny :)
I made them with instant but didn't know I had to much water in the pot when I started to make them. So taking the idea about the 10 mins thing and running with it.... so here goes...
I'd do what Kim does. A handful of instant. I don't want to wait ten more minutes if I've planned them to be done when the main course is.
Husband whipped up 5 lbs. of taters while I added 1 stick or 1/2 cup of butter resulting in yummy runny mashed potatoes.
Our question is how to stiffen them back up?

I would try adding some instant potato flakes and see if that helps. You only want to add a few at a time.
I agree, adding more instant potato mix would be perfect.
Instant potatoe flakes will work.
If you don't have instant potatoes on hand, tapioca makes a good thickener.
