Instructions

  1. Step 1

    Slice kielbasa on the bias into 1/2-inch-thick rounds. Slice onion into thin rings.

  2. Step 2

    Heat oil in a large skillet over medium-high. Add onions, stir often until golden and charred, 6–7 minutes.

  3. Step 3

    Push onions to the side. Lay kielbasa slices flat on the hot skillet in a single layer.

  4. Step 4

    Sear kielbasa without moving for 2 minutes, then flip and sear 1–2 minutes more until edges are browned.

  5. Step 5

    Drizzle mustard over the kielbasa and onions. Toss to coat, cooking 30 seconds until glossy.

  6. Step 6

    Season with salt and pepper. Serve hot from the skillet.
