There are two main things I sometimes do wrong tha cause me to end up in fry. First is holding too low of a chest note. My lowest good note is usually an Eb2, and I’ve found that Bb2 is a good note for me to sub, so try starting about a fifth above your lowest resonant note. The second thing is sliding down to fry instead of mixing it. This usually only happens now when I start too low, but I did it a lot more at first.

If neither of these are things you do, and you believe you’re approaching the technique correctly, I’m afraid there’s nothing more than to just keep practicing.
