Chicken, Chive, and Feta Zucchini Fritters

2 zucchini, grated

1 teaspoon salt

¾ cup all-purpose flour

4 eggs

2 tablespoons milk

1 teaspoon seafood seasoning (such as Old Bay®)

½ teaspoon salt

½ teaspoon ground black pepper

¾ cup cubed cooked chicken

⅔ cup crumbled feta cheese

½ cup chopped fresh chives

⅓ cup vegetable oil, divided

½ cup sour cream

Toss zucchini with 1 teaspoon salt in a colander and drain for 10 minutes. Wrap vegetables in a clean kitchen towel and squeeze out as much moisture as possible; transfer mixture to a bowl.

Whisk flour, eggs, milk, seafood seasoning, 1/2 teaspoon salt, and black pepper together in a bowl until smooth. Stir zucchini, chicken, feta cheese, and chives into the batter until well blended.

Heat about 3 tablespoons vegetable oil in a skillet over medium-high heat; pan-fry heaping tablespoonfuls of batter in the hot oil in batches, flattening fritters with a spoon to about 3-inches wide, until golden brown, 2 to 3 minutes per side. Transfer fritters to a paper towel-lined plate. Repeat with remaining vegetable oil and batter. Serve with sour cream.
