I make a recipe of my own creation almost exactly like this pretty often but I add more onion and add them a bit sooner than you do or even before i begin to cook the potatoes because i like mine carmelized. Your way is still absolutely delicious though !
These were delicious, even though I don't have a cast-iron skillet. Plus, it's a quick and easy weeknight meal since the potatoes don't need to be peeled and are precooked the evening before. I steamed the potatoes in the microwave to get them fork-tender. The spices were perfect. I added some Portuguese sausage to make it a one-dish meal. Thanks Kitten!
