bump. this made me hungry tonight.
sometimes you have to tell the polish guy to step out of the pot and put the sausage back in... bah dum dump, crash!
but seriously, my wife makes her mom's recipe of polish sausage (which also works with kielbasi) baked with onions, saurkraut, and potatoes.
she steams the sausage a bit but not cooked through and sets it aside. next, she sweats thinly sliced onions in butter and mixes that into the sauerkraut at about an equal ratio, or maybe just a bit more kraut.
while doing this, she parboils peeled and sliced potato rounds (about 1/4 inch thick slices), and drains them.
the kraut/onion is mixed gently with the potatoes and placed in a deep casserole dish. the steamed sausage is nestled into the mixture and it is baked uncovered at i think around 350F until the edges of the kraut and onions begin to crisp and brown, and the sausage is cooked through.
i'm not sure if she dots the top with butter before baking. i'll have to ask.
some people like to sprinkle it with caraway seeds, but we pefer it without.
serve with a spicy brown mustard, and a side of polish rye bread and maslo (polish or slovakian spreadable butter).
