Dietary: High-protein, Comfort food

Ingredients:
For the Meatballs:

1 lb ground beef

1 large egg

1 small onion, finely diced

4 garlic cloves, minced

¼ cup fresh parsley, chopped

½ cup Panko breadcrumbs

¼ cup grated Parmesan cheese

½ tsp dried basil

½ tsp dried oregano

½ tsp salt

Freshly ground black pepper, to taste

4 oz fresh mozzarella, cut into 12 cubes

For Cooking & Serving:

1–2 tbsp olive oil

2 cups marinara sauce

Chopped fresh parsley (for garnish)

Grated Parmesan cheese (for serving)

Instructions:
Prepare Meatball Mix: In a large bowl, combine beef, egg, onion, garlic, parsley, breadcrumbs, Parmesan, basil, oregano, salt, and pepper. Mix thoroughly with hands until evenly blended.

Stuff with Cheese: Flatten about 2 tablespoons of meat mixture in your palm, place a mozzarella cube in the center, and seal the meat around it. Roll into a ball. Repeat for 12 meatballs.

Sear Meatballs: Heat olive oil in a large skillet over medium-high. Sear meatballs 2–3 mins per side until browned. Work in batches if needed.

Simmer in Sauce: Add marinara sauce to pan, covering all meatballs. Reduce heat to medium-low, cover, and simmer for 10 minutes. Flip meatballs halfway through.

Check Doneness: Ensure internal temp reaches 160°F and cheese is melted.

Serve & Garnish: Serve over pasta, polenta, or bread. Top with chopped parsley and grated Parmesan.

Additional Notes:
Use a meat thermometer to guarantee perfect doneness.

Fresh mozzarella provides the best melt; avoid pre-shredded types.
