Position the oven rack in the middle and preheat to 425°F.
Whisk paprika, onion powder, salt, cumin, oregano, garlic powder, cayenne, and black pepper together in a small bowl until evenly combined.
Add chicken thighs to a large mixing bowl with lemon juice, Greek yogurt, olive oil, and minced garlic. Sprinkle in the spice blend and mix until every piece is thoroughly coated.
Arrange thighs on a sheet pan, smooth side down, with minimal overlap so they brown evenly.
Bake 30–40 minutes, until nicely browned and the thickest piece reaches an internal temperature of 165°F.
Cool on the pan for at least 30 minutes before portioning to protect food safety and fridge temperature.
Portion 2 thighs per container (or as desired), label with the date, and refrigerate on a middle shelf where the temperature is most consistent.
