Firstly, thaw your meatballs.
Set the temperature of the oven at about 150 °C, i.e., 300 °F, and let the oven preheat for about 10 to 15 minutes before popping the meatballs inside.
In the meantime, carefully take the meatballs out of the package and place them on a parchment-paper-covered baking tray. Make sure to leave enough space between the meatballs, and don't place them too close to each other.
Spray the meatballs with cooking oil to add a little moisture to their surface.
Bake them for about 15-20 minutes at around 375 °F, i.e., 190 °C. Check the level of doneness of your meatballs after about ten minutes.
Your meatballs should be done after about 17 minutes, but if you want to make sure, try one, and if it's done, remove them from the oven.
Let your meatballs rest for ten minutes before you serve them.
Serve your meatballs with one of the recommendations from the article, and enjoy!
