Refrigerate the meat mixture for at least 30 minutes before rolling—this prevents the meatballs from falling apart during cooking and ensures they stay moist and tender.

Mix ingredients gently with your hands just until combined; overworking develops gluten in almond flour and makes meatballs dense and tough instead of light and fluffy.

Brown meatballs in a hot skillet for 2-3 minutes per side before adding marinara sauce to create a flavorful crust that locks in juices and adds depth.

Tear fresh basil leaves and stir into the sauce just before serving to preserve their vibrant flavor and aromatics that heating destroys.

Always use freshly grated Parmigiano-Reggiano rather than pre-grated varieties, which contain anti-caking agents that prevent proper melting and binding in your meatballs.
