To deep fry chicken wings, follow these key steps for crispy and delicious results:

1. Heat oil (peanut, vegetable, or canola oil) in a deep pot or fryer to about 350-375°F.
2. Season or marinate chicken wings to taste, then optionally dip in an egg wash and dredge in a seasoned flour mixture for a crispy coating.
3. Carefully lower the wings into the hot oil in batches, avoiding crowding.
4. Fry the wings for about 8-10 minutes, flipping occasionally, until the skin is golden brown and an internal temperature of 165°F (75°C) or higher is reached.
5. Remove wings and drain excess oil on paper towels or a wire rack.
6. Serve immediately plain or tossed in sauce.

This method results in wings that are crispy outside and juicy inside, commonly cooked in restaurants but easy to do at home with a thermometer for best results.
