I didn't find it too salty; I think the kind of bacon you use could make a huge difference. I also used kosher salt, which is what Ina uses; regular salt measures differently than kosher salt as the grains are smaller. This could be another reason that some find it too salty. If you use salted rather than unsalted butter that would also add more salt.

I don't know if any of these apply in your case; just throwing out ideas.
