Step 1

Heat a large cast iron skillet with a drizzle of canola oil over medium-high heat until it just starts to smoke.

Step 2

With a fork, poke a few holes on each side of the bratwurst sausage to keep them from bursting while they cook.

Step 3

Place the brats in the hot skillet, then place the onions around them.

Step 4

Stir the onions to spread them around and to coat with oil.

Step 5

Cook the brats for about 4 minutes per side, or until they are nicely browned.

Step 6

Carefully pour 1/2 cup water in the skillet, then immediately cover and reduce the heat to medium-low.

Step 7

Cook covered for about 10 more minutes, or until the internal temperature reaches 160 degrees.

Step 8

Remove the lid and the brats from the skillet.

Step 9

Increase the heat and season the onions with salt and continue to cook the onions for a few more minutes to reduce the liquid.

Step 10

Serve the sausages topped with the onions and your favorite mustard.
