To bake meatballs in the oven, preheat the oven to 375°F to 400°F depending on the recipe. Here are the general steps to follow:

1. Mix all the ingredients together in a bowl. Knead the meat mixture so that everything is evenly mixed together.
2. Roll the meat mixture into 1 to 1.5 inch meatballs and place them on a baking sheet lined with parchment paper or foil.
3. Bake the meatballs in the oven for about 15-30 minutes, depending on the size of the meatballs and the oven temperature. The internal temperature of the meatballs should be at least 160°F.

Here are some additional tips to keep in mind:

• Leave enough space between the meatballs on the baking sheet to ensure even cooking.
• Cover the meatballs with aluminum foil if they begin to over-brown.
• Use a meat thermometer to check for doneness.
• You can lightly coat your hands with olive oil or cooking spray before rolling the meatballs to prevent them from sticking.
• You can also freeze the meatballs for later use.
