Heat oil in deep fryer or pot on stove to 375 degrees Fahrenheit
Mix flour, salt and pepper and place in shallow dish. Beat eggs and milk in another shallow dish. Place bread crumbs in a third shallow dish.
Coat the zucchini sticks in each shallow dish starting with the flour mixture, then the eggs and finally the bread crumbs.
Mix the sour cream and ranch in a small dish and set aside. This will be the dip for your zucchini sticks.
Place in hot oil and fry until golden brown, about 3-4 minutes. Remove sticks and place on paper towel for a couple minutes to drain oil. Serve with dip and enjoy.
