Preheat and prep: Heat your oven to 400°F (200°C).
Line a baking sheet with parchment or lightly oil it. If pan-searing, set a large skillet over medium heat.
Blend the cottage cheese: For the smoothest texture, pulse the cottage cheese in a blender or food processor for 10–15 seconds. This step removes curds and makes ultra-tender meatballs.
Mix the aromatics: In a large bowl, combine the blended cottage cheese, egg, garlic, grated onion, parsley, Parmesan, salt, pepper, and red pepper flakes.
Stir until evenly combined.
Add breadcrumbs and meat: Sprinkle in the breadcrumbs, then add the ground turkey or chicken. Gently mix with a fork or your hands until just combined. Do not overwork—that can make the meatballs tough.
Chill briefly: If the mixture feels soft, refrigerate it for 10–15 minutes. This makes shaping easier and helps the meatballs hold their form.
Shape: Scoop and roll into golf-ball-sized meatballs (about 1.5 inches / 4 cm).
You should get 16–20 meatballs.
Choose your cooking method: Bake: Place meatballs on the prepared sheet, drizzle or mist lightly with olive oil. Bake 14–18 minutes, or until the centers reach 165°F (74°C). For extra browning, broil the last 1–2 minutes.
Pan-sear: Heat 1–2 tbsp oil in a skillet.
Add meatballs and cook 8–10 minutes, turning to brown on all sides, until cooked through.
Air-fry: Air-fry at 375°F (190°C) for 10–12 minutes, shaking halfway, until browned and at 165°F (74°C).
Serve: Toss with warm marinara, spoon over zucchini noodles or pasta, or serve with a crisp salad and roasted vegetables. A squeeze of lemon and extra parsley brighten the flavors.
