Triple Meat Italian Meatballs

Preheat your oven to a temperature of 350 degrees Fahrenheit, or 175 degrees Celsius for those using metric measurements.

Take a large mixing bowl and merge together ground meats, finely chopped onion, eggs, bread crumbs, rolled oats, and your preferred seasonings until everything is harmoniously incorporated.

Using your hands, mold the combined mixture into 24 identical spheres, approximately 2 inches in diameter each. This will form your meatballs.

In a large skillet, heat an adequate amount of vegetable oil to a depth of about half an inch. Carefully place the meatballs into the hot oil and cook until they're nicely browned on all sides, taking roughly 5 minutes.

Transfer the cooked meatballs to a suitable-sized glass baking dish. This will serve as their resting place before they're baked further.

Place the prepared meatballs in the preheated oven and bake for 25 minutes. To ensure they're cooked through, insert an instant-read thermometer into the center of a meatball and verify that it reaches a temperature of 165 degrees Fahrenheit, or 75 degrees Celsius.
