Preheat the oven to 400°F and line a baking sheet with parchment paper or lightly grease it.
In a large bowl, add the ground chicken, pesto, almond flour, Italian seasoning, salt, and pepper. Gently mix until just combined, avoid over mixing to keep the meatballs tender.
Using a cookie scoop or your hands, portion the mixture into 1½-inch meatballs and place them evenly spaced on the prepared baking sheet.
Bake for 18–20 minutes, or until the meatballs are cooked through and reach an internal temperature of 165°F.
Remove from the oven and let rest for 2–3 minutes before serving.
Serve warm with extra pesto for dipping or alongside vegetables or spaghetti squash.
