Make the Lemon Gremolata.Mix parsley, lemon zest, grated garlic, and salt. Set aside.

Weigh down with another skillet.Roast at 400°F for 10 minutes. Lower heat to 350°F and cook 30–45 minutes until internal temperature reaches 165°F.Remove top skillet, flip skin side up, and roast again at 400°F for 5–10 minutes until deeply crispy. Rest 10 minutes.
Make the Spinach Purée.Bring a pot of salted water to a boil. Blanch spinach for 30 seconds, then immediately transfer to ice water. Squeeze completely dry.Blend with neutral oil until completely smooth. Measure 130 g for the dough.
Prepare the Spinach Spaetzle Dough.Whisk eggs, sour cream, spinach purée, and salt until smooth.Add flour and baking powder. Whisk aggressively until thick and pasty.Rest 10–15 minutes.

Notes
Chill the spaetzle before sautéing for the best crispy texture.
Weighing the chicken ensures ultra-crispy skin.
Do not over-thin the spaetzle batter. It should be very thick.
