@JLNobody,
So I think I've perfected my home-made homefries, I think. In my ever-so-humble-opinion.
Start pan on medium heat. Add oil to coat.
Dice potato or potaoes to 1/2" to 3/4". Add to pan once oil is hot. Spread potatoes as thinly as possible over bottom of pan.
Cover. This is important. I find that a reflective metal cover is more effective than a glass cover, though that could be placebo effect.
Coarsely chop onion (1/2 a large yellow onion per medium potato). Put on top of potato. Mince some garlic. Put this over onion. Re-cover pan.
Grind together with mortar and pestle: rosemary, thyme (small amt), parsley, whole cumin seed, coriander, paprika, black pepper, sea salt/kosher salt. Grind with pestle.
Shake this mix evenly over contents of pan. Stir contents of pan to evenly distribute ingredients and seasoning mix. Add a little bit of chicken stock (about a tablespoon per potato). Reduce heat to low-medium. Re-cover.
This'll sit for a few minutes, until the edge of a spatula easily cuts one of the larger pieces of potato.
Two options now. You can dump the whole mix into an oiled pan over medium-high heat, or you can turn up the heat in the pan you're using to medium-high. The former is more effective, but makes for more clean-up, obviously, and uses more energy.
Cook in the hot pan long enough for the surfaces of the potato to start to brown. If you're lucky, the onions may caramelize a bit, too.
I've spent years trying to figure out how to make good homefries without leftover baked potatoes and a restaurant flat-top grill, and I think I've finally got it.
Mmmmm, brekkie.
