1. Preheat oven to 425°F. Line a baking sheet with parchment paper for a little less cleanup.
2. Whisk to mix smoked paprika, brown sugar, oregano, salt, and pepper in a small bowl.
3. Place chicken in a large bowl. Drizzle with avocado oil. Sprinkle on the seasoning mix and toss to coat. Transfer the chicken drumsticks to the prepared baking sheet in a single layer.
4. Bake for 20 minutes. Flip and cook for an additional 15-20 minutes or until the chicken is cooked through and no longer pink. Chicken is considered safe to eat when a food thermometer inserted into the thickest part reads 165°F. However, dark chicken meat, such as drumsticks, can benefit from cooking to a higher internal temperature (175°F-190°F) to help tenderize the meat. 
5. Serve warm.

Storage: Store leftovers in an airtight container in the fridge for use within 3 days. Reheat in an airfryer or oven at 350°F for 7-8 minutes, or until warmed through and the skin starts to crisp up again.
