Give em a pre-soak to remove some of the starch from the potatoes, thoroughly dry em and proceed as normal, but fry em again at a slightly higher temp after they’ve had a min or two to rest after the first fry.

That’s pretty consistently good in my experience

Do you grill, pan fry, broil, other(?) I love grilled burgers, but it’s a hassle vs popping something in the oven. And flat top grills are even better, but 10x the mess to clean up. Pan fried never tastes that great for me. But maybe I don’t know what I’m doing.
