NEAPOLITAN MEATBALLS WITH RAGU

Steps:

• Heat the oven to 475 degrees F with a rack in the middle position. Line a rimmed baking sheet with parchment and mist with cooking spray. In a large Dutch oven over medium-high, heat 2 T oil until shimmering. Add the onion and 1/2 t salt, then cook, stirring occasionally, until softened, about 5 minutes. Add the garlic and 1 t pepper flakes, cook, stirring until fragrant, about 30 seconds. Remove the pot from the heat, then transfer half of the onion mixture to a large bowl.
• In a medium bowl, combine the panko and 1 1/4 C water; press the panko into the water and let stand until fully softened, about 5 minutes. Mash with your hands to a smooth paste, then add to the bowl with the onion mixture. Using a fork, mix until well combined and smooth. Stir in the grated cheese, beaten eggs, the remaining 2 T oil, 1 1/2 t salt and 2 t black pepper. Add the meat and mix with hands until completely homogenous.
• Using a 1/2-cup dry measuring cup, divide the mixture into 8 portions. Using your hands, shape each into a compact ball and place on the prepared baking sheet, spacing them evenly apart. Refrigerate uncovered for 20 minutes. Re-shape the meatballs if they have flattened slightly, then bake until lightly browned, about 20 minutes. Let cool on the baking sheet set on a wire rack for about 10 minutes.
• While the meatballs cook, in a food processor or blender, puree the tomatoes one can at a time with their juices until smooth, about 30 seconds, transferring the puree to the Dutch oven with the remaining onions. Add remaining 1/2 t pepper flakes, the basil and the chunk of cheese. Bring to a simmer over medium-high heat and cook, stirring occasionally, until slightly thickened, about 15 minutes. Taste and season with salt and pepper.
• Using a large spoon, carefully transfer the meatballs to the sauce, then, using 2 spoons, turn each to coat. Bring to a gentle simmer, then reduce to medium-low, cover and cook for 5 minutes. Remove the pot from the heat and let stand, covered, for about 5 minutes to allow the meatballs to firm up slightly. Remove and discard the cheese chunk. Serve with additional grated cheese.
