In a medium skillet, heat oil over medium heat. Add onion and garlic; cook, stirring occasionally, until onion begins to become translucent, 3 to 4 minutes. Add blueberries, lemon juice, vinegar, and brown sugar. Reduce heat to medium-low, and cook, stirring occasionally, until blueberries start to release their juices, about 2 minutes. Add salt, pepper, chili powder, and paprika. Cook, stirring occasionally, until berries are soft and bursting, 8 to 10 minutes. Remove from heat.
Pour blueberry mixture into a heatproof container. Using an immersion blender, blend mixture until smooth. Let cool completely. Refrigerate until ready to serve or for up to 1 week.
