NOTE: If you are using gizzards from home-butchered birds, start step 1. Otherwise go straight to step 5 (trimming off the fat).
Trim any remaining bits: If your gizzards still have pieces of intestine or the esophagus attached, carefully remove them with a sharp knife so your gizzards are clean and ready for cooking.
Cut open the gizzards: Using a sharp knife, make a shallow slit along each gizzard. Be careful not to cut too deep — you don’t want to pierce the internal membrane. Don’t worry if it happens; simply clean the gizzard, and it will still be usable.
Open the gizzard: Gently pull the sides of the slit apart to remove the inner membrane and any small remnants of grain, grit, or food the chicken recently ate.
Clean out the remaining membrane: Remove any larger pieces of yellow membrane inside the gizzard. Tiny remnants are fine — they won’t affect the flavor or texture.
Trim the fat: Chicken gizzards naturally carry quite a bit of fat. Remove most of it with your hands — leaving it on will make the broth greasy. You can render the fat into schmaltz for sautéing vegetables.
Rinse the gizzards: Rinse the gizzards thoroughly under running water to remove any remaining bits or debris.
Add gizzards to the pot: Place the cleaned gizzards in a cooking pot, ready for the broth.
Add aromatics: Add onion, garlic, celery, bay leaf, peppercorns, and salt. You can cook gizzards in plain salted water, but aromatics make a flavorful broth that can replace stock or bone broth in recipes.
Add water and bring to a boil: Pour in enough filtered water to cover the gizzards and aromatics by about 2 inches. Cover the pot and bring to a gentle boil.
Skim and simmer: Skim off any foam that rises to the surface — no need to remove every bit. Reduce heat to low, cover the pot, and simmer gently for 1½–2 hours, or until gizzards are fork-tender.
Strain the broth and cool gizzards: Strain the broth into a separate container and transfer the gizzards to a bowl. Let them rest until cool enough to handle.
Slice or chop: Depending on your recipe, leave gizzards whole, or slice/chop them into pieces. For soups, slicing into a few pieces works perfectly.
