My mother taught me this recipe, but she made her croquettes with canned salmon. You could also make this with tuna.
3 cups finely shredded/chopped cooked chicken, tuna, or salmon
1 large onion, finely diced
2 eggs, beaten
1/3 cup milk
1 2/3 cup seasoned bread crumbs
1/2 cup grated Parmesan cheese
1/2 cup grated Italian blend cheese
2 Tablespoons creole mustard
2 Tablespoons parsley flakes
1 tsp. garlic powder
1 tsp. pepper
1 Tablespoon Tony Chachere's seasonings
1 cup oil for frying (I use canola)
In a large mixing bowl, add beaten eggs and milk and mix well. Add all ingredients other than oil and fold/blend well.
In a large skillet, heat oil on medium high
Scoop up a handful of mixture and form into a patty. Place in heated oil and fry each side for 4-5 minutes until golden brown. Drain on paper towels when removed from oil.
