1large sweet onioncut into 1/2" pieces, about 1 cup's worth
3medium russet potatoescut into 1/2" pieces, about 4 cup's worth
1tablespoonminced fresh rosemary
1/4teaspoonfreshly ground black pepper
Melt the butter in a large skillet over medium high heat. Add the onions, toss to coat and then cook for about 5 minutes, stirring occasionally, until they are soft and browned. Add the potatoes to the skillet, drizzle lightly with oil and then sprinkle with rosemary, salt and pepper. Stir to combine and then spread flat across the skillet.
Cover with lid and reduce heat to medium. Let the potatoes cook for 10 minutes. Stir and cover with lid again. Cook 5 more minutes. Remove lid, stir and cook uncovered, for about 5 more minutes, stirring occasionally until the potatoes are browned. The potatoes should be soft and well browned. Serve as is, or increase the heat to medium high and continue cooking in an open skillet, stirring every 2-3 minutes, until slightly crispy. Serve hot or let cool and store in the refrigerator until ready to serve. Potatoes can be reheated in a hot skillet for a few minutes just before serving. Enjoy!
