Preheat the oven to 400 degrees F. Line a large rimmed baking sheet with parchment paper.: The smell of a hot oven is reassuring; you want it fully warmed so the meatballs begin to set immediately on contact, which helps create a slightly crisp exterior. If the oven is not fully preheated, the meatballs may release more liquid and become softer. Common mistake, rushing this step leads to uneven browning. Listen for the faint hum of heating elements, and watch for steady temperature before inserting the tray.
Set out a large mixing bowl. Add the ground turkey, almond flour, eggs, scallions, basil, garlic, fish sauce, lemongrass, and crushed red pepper. Mix until well combined with a smooth texture. (Don't overmix!): The tactile feel of the mixture should be cohesive and slightly tacky, not soupy. Mixing releases proteins that bind the ingredients, giving a tender interior when handled properly. Overmixing will make the texture dense and gummy. If the bowl feels too wet, a small extra tablespoon of panko or almond flour can help, but add sparingly so you do not dry the meat.
Use a 1.5 tablespoon scoop to portion out balls. Gently roll the balls and lay them on a baking sheet. The meat mixture will be very soft and sticky, so try not to roll the balls too much.: The tactile image here is soft, yielding, and slightly sticky hands; gentle shaping keeps the meatballs airy. Overworking will compact the mix and tighten the crumb, robbing tenderness. If the mixture clings excessively, wet your hands or lightly oil them to prevent sticking. Arrange the balls with space between them to allow hot air to circulate and promote even browning.
Once all the balls are formed. Warm the coconut oil, then drizzle it over the tops of the meatballs.: The warm oil brings out the aromatics and encourages the tops to brown and glisten in the oven, signaling caramelization. If you pour cold oil it may sink and not coat evenly. A common slip is using too much oil; a gentle drizzle is enough. The oil will add a faint, toasty scent as it heats and help the tops develop a light crust without frying.
Place the meatballs in the oven for 10 minutes. Then flip each meatball and place back in the oven for another 10 minutes. Serve warm.: During the first bake you should notice gentle oven steam and a subtle herb fragrance. After flipping, the second bake develops even color and ensures the centers reach a safe temperature. If you skip flipping, one side may brown more than the other. Test for doneness by checking that the internal temperature registers safely and the juices run clear; the texture should be springy, not raw or overly firm.
