Peel and thinly slice the onions from root to tip. Uniform slices help ensure even cooking and a smooth texture in the finished dish.
Step 2: Prepare the Liver
Rinse the pork liver under cold running water and pat dry with paper towels. Remove any visible membranes or connective tissue for the most tender results.
Step 3: Lightly Coat with Flour
Place the flour in a shallow bowl. Lightly dredge each liver slice, shaking off any excess.

This simple coating helps create a rich, traditional gravy during cooking.
Step 4: Layer the Ingredients
Spread half of the sliced onions evenly across the bottom of a 4- to 6-quart slow cooker.
Arrange the floured liver slices over the onions in a mostly single layer.
Top with the remaining onions, covering the liver as evenly as possible.
Step 5: Add Liquid
Pour the water gently into the slow cooker until the ingredients are nearly covered.
Season with salt and pepper if desired.
Step 6: Slow Cook Until Tender
Cover and cook:
- LOW: 6–7 hours
- HIGH: 3–4 hours
The liver should become tender while the onions soften into a flavorful gravy.
Step 7: Serve
Carefully stir the onions and gravy before serving.
Spoon generously over your favorite side dishes and enjoy while warm.
