Preheat your oven to 400°F (200°C) to ensure even cooking.
In a large mixing bowl, combine the ground chicken, minced shallot, panko breadcrumbs, grated parmesan, basil pesto, egg, salt, and black pepper. Mix gently until just combined.
Shape the mixture into 1.5-inch meatballs and place them on a baking sheet lined with parchment paper.
Bake the meatballs in the preheated oven for 18-20 minutes, until cooked through and reach an internal temperature of 165°F (74°C).
Remove from the oven and let cool slightly before serving. Enjoy with marinara sauce, over pasta, or in a sub sandwich.
