First things first, grab a large mixing bowl. Into that bowl, you're going to add your ground chicken.
Now, toss in all the other ingredients: the grated parmesan cheese, blanched almond flour (or your gluten-free breadcrumbs), minced garlic, the grated and dried onion, Italian seasoning, sea salt, black pepper, and the large egg.
Time to mix! This is where you get your hands a little messy, or you can use a spoon or spatula. Gently mix everything together until it's just combined. Be careful not to overmix, as this can make the meatballs tough.
Once everything is mixed, it's time to form the meatballs. I usually make mine about 1 to 1.5 inches in diameter, roughly the size of a golf ball or a little smaller. You should get around 18-20 meatballs from this batch. A small scoop can help keep them uniform in size, which helps them cook evenly.
Now, grab a large skillet and heat the olive oil over medium heat.
Carefully add the meatballs to the hot skillet, making sure not to overcrowd the pan. You might need to cook them in batches.
Let them cook for about 3-4 minutes per side, turning them gently, until they are beautifully browned all over and cooked through. To be sure they're done, you can check the internal temperature with a meat thermometer – they should reach 165°F (74°C).
Once they're cooked, remove them from the pan and place them on a plate lined with paper towels to drain any excess oil.
And that's it! You've made delicious chicken meatballs, ready to be served however you like!
