Just use double quotes around the value, as you did in the variable assignment:

echo "$ASDF"
Double quotes don't prevent variable substitution, but protect the asterisk from the filename expansion. Quoted from

Using double quotes the literal value of all characters enclosed is preserved, except for the dollar sign, the backticks (backward single quotes, ``) and the backslash.

Another way to interpret it is that double quotes create a new string based on its contents and keeps it as is or prevents it from being re-expanded or re-parsed from the outside.
