Preheat Oven:

• Set oven to 400°F (200°C).

• Line a rimmed baking sheet or large pan with foil.

• Place the pan in the oven while it preheats — you want it hot when you add the chicken.

Make Seasoning Paste:

• In a large bowl, mix together olive oil, garlic powder, onion powder, paprika, Italian seasoning, parsley, salt, and pepper until a thick paste forms.

Season Chicken:

• Add chicken thighs to the bowl (work in batches if needed).

• Toss to coat well, rubbing the seasoning under and over the skin for maximum flavor.

Bake:

• Carefully remove the hot pan from the oven and place the chicken thighs skin-side up.

• Dot each piece with a bit of butter.

• Bake for 20 minutes, then remove and baste the chicken with the pan juices.

• Return to the oven for another 10 minutes, baste again, and bake an additional 5–15 minutes until the internal temperature reaches 165°F (74°C).

Serve:

• Let rest for 5 minutes before serving for the juiciest results.
