Gather all your ingredients on the counter.

In a large mixing bowl, combine ground beef, Parmesan cheese, eggs, minced garlic, parsley, salt, pepper, Italian seasoning, and red pepper flakes.

Using your hands, form the mixture into 1-inch meatballs.

Heat olive oil in a skillet over medium heat.

Add the meatballs to the skillet, making sure not to overcrowd them.

Cook the meatballs for about 10 minutes, turning occasionally.

Use a cooking thermometer to check if the meatballs have reached an internal temperature of 160°F.

Remove the meatballs from the skillet and let them rest for a few minutes.
