Before You Begin
Preheat and prepare your cookware as needed. Cooking times and results may vary depending on your equipment and ingredients.
Step 1 — Prepare the Oven
Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper to help prevent sticking.
Step 2 — Mix the Meatball Base
In a bowl, combine ground chicken, Parmesan, breadcrumbs, egg, milk, garlic, onion, and seasonings. Mix gently until just combined.
Visual cue: Mixture should look evenly blended but not compacted.
Step 3 — Shape the Meatballs
Scoop and gently roll into 1½-inch balls. Arrange on the baking sheet with space between them.
Step 4 — Bake the Meatballs
Bake until the meatballs look lightly golden and feel firm when pressed. Cooking time is typically about 18–20 minutes, depending on oven performance and meatball size. Meatballs should appear opaque in the center and release clear juices.
Step 5 — Add Sauce and Cheese
Spoon marinara over each meatball and top with mozzarella.
Step 6 — Melt and Finish
Return to the oven for 3–5 minutes, or until cheese is melted and bubbling.
Step 7 — Serve
Let rest briefly and serve warm.
Cooking Notes
Mix the meatball mixture gently to keep the texture tender.
Shape meatballs evenly so they bake at the same rate.
Bake until the meatballs are opaque in the center and release clear juices.
Add the sauce and cheese only after the initial bake to prevent sogginess.
Cooking times may vary depending on oven performance and meatball size.
