Cajuns love them for sauce pecante.

One of my roommates in college was from Breaux Bridge, La. His family had a house boat out on the Bayou. They got together out there regular and I got to go a few times.
They kept a few Softshell AND Alligator Snapping turtles in a big floating cage just for that.
When his Mama, Aunts, and Grandmas would get in that kitchen and start yelling at each other in French, I KNEW that something REAL GOOD was cooking!
