What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Cut the sausage on a bias to increase surface area and get more crispy edges.
- 2Don't move the sausage while searing — let it form a deep, brown crust undisturbed.
- 3If onions start to scorch, deglaze with a splash of water and scrape up the fond.
- 4Use a heavy-bottomed skillet (cast iron works great) for even browning.
- 5Make ahead: caramelize the onions up to 3 days in advance; reheat and add sausage.
- 6Serve leftovers piled onto a hoagie roll with extra mustard for a killer sandwich.
