Line a baking sheet with parchment paper.
Add the ground chicken, egg and seasonings to a bowl and mix until well combined.
With wet hands, scoop about 2 tablespoons of the chicken mixture and shape it into a chicken nugget shape.
Add the nuggets to the lined baking sheet and repeat with the rest of the chicken mixture. (You should have about 22-25 nuggets.)
Place the baking sheet into the freezer for at least 1-2 hours or until firm. (This helps the nuggets hold their shape when coating and frying.)
Meanwhile, prepare one bowl with cornstarch.
In a second bowl, whisk together the flour, seasonings, and club soda until a thick batter forms.
Fill a large pot or deep skillet with oil, about 2 inches deep. Heat the oil over medium-high heat until it reaches 350°F to 365°F.
Once the oil is hot, take the firm chicken nuggets and coat them in the cornstarch, then dip them into the wet batter, fully coating the entire chicken nugget.
Carefully add the coated nuggets to the oil and fry for about 2-3 minutes per side, until crispy and golden brown.
Repeat with the remaining chicken nuggets until all are crispy and golden brown.
Transfer the fried nuggets to a paper towel–lined plate or wire rack while you fry the remaining nuggets.
Add the chicken nuggets to a serving plate and serve immediately with your favorite sides and dipping sauces.
