Step 1

Toss the potatoes with the onion, flour and salt and pepper; set aside for about 10 minutes.

Step 2

Meanwhile heat the fat in a Dutch oven or other heavy lidded pot. Add the potato mixture to the hot oil and cook until heated through, stirring to coat. Add the milk and bring to a boil, stir, reduce to a simmer, cover and cook, stirring occasionally about 15 minutes, or until potatoes are tender.

Step 3

Remove cover, taste, adjust salt and pepper, and continue cooking on simmer, uncovered, until the potatoes and gravy reach desired consistency. Serve immediately.
