Let’s walk through the steps to make these delectable meatballs. Remember, cooking is a journey, and each step is an opportunity to infuse love and care into your dish.

1. Preheat your oven to 375°F (190°C) and lightly grease a baking sheet with olive oil.
2. In a large bowl, combine the ground beef, chopped spinach, minced garlic, breadcrumbs, Parmesan cheese, salt, pepper, oregano, and beaten egg. Mix until just combined. Avoid over-mixing to keep the meatballs tender.
3. Take about two tablespoons of the meat mixture and flatten it slightly in your palm. Place a mozzarella cube in the center and fold the meat around it to form a ball. Make sure the cheese is fully enclosed.
4. Place the meatballs on the prepared baking sheet, ensuring they are evenly spaced.
5. Bake the meatballs in the preheated oven for 15-20 minutes, or until cooked through and nicely browned.
6. Meanwhile, warm the marinara sauce in a saucepan over medium heat.
7. Once the meatballs are ready, gently transfer them to the saucepan, letting them simmer in the marinara sauce for an additional 5 minutes to absorb the flavors.
8. Serve the meatballs hot, with a generous spoonful of marinara sauce over each one.

There’s something magical about watching that mozzarella ooze out as you cut into each meatball — a little reminder of the joy and surprise home-cooked meals can bring.
