I don’t think i ever made potato kugel in my life. Just Shabbos crockpot chicken and tri-color potatoes (surrounding a whole onion).
As for Pesach, before Y”T i make over 30 potato-veggie latkes which are YUM containing potato, sauteed onion/celery, turnip, carrots, parsnip, zucini. And on Shabbos-Pesach i keep the chicken-plus-latke, lidded-frying-pan, along with veg-soup pot, on the blech near the gas, though not above it.
