The temperature to bake meatballs varies slightly depending on the recipe, but most recipes suggest baking meatballs in a preheated oven at 375°F to 400°F. Here are the recommended baking temperatures and times from some of the search results:

• The Black Peppercorn: Bake in a 400°F oven until cooked through, about 20-24 minutes.
• Allrecipes: In an oven preheated to 350°F, these meatballs should be fully cooked through and evenly browned in about 30 minutes.
• The Typical Mom: Preheat oven to 350°F and place desired number of meatballs in a single layer on a baking sheet. Bake for 15-20 minutes until outside is browned.
• The Slow Roasted Italian: For their baked meatball recipe, they use a temperature of 375°F so they cook faster and each meatball is perfectly browned. Meatballs cook in about 20-25 minutes.
• Recipes From A Pantry: Preheat oven to 400°F. Bake the meatballs for 19-25 minutes until browned and cooked through. The internal temperature should be a minimum of 160°F when inserted into the center of the meatball.
• Culinary Hill: Preheat the oven to 400°F. Bake until browned and crispy, about 15-20 minutes, or until an internal thermometer reads 165°F for 15 seconds.

Its important to note that the internal temperature of the meatballs should reach at least 160°F to ensure they are fully cooked. Using a meat thermometer is the best way to check the internal temperature of the meatballs.
