Preheat the oven to 350 F. Prepare a baking dish, similar to a 9x13 inch casserole pan, optionally lined with foil or parchment paper for easier cleanup.
In a large mixing bowl, add all meatball ingredients and mix well. Form into 16-18 meatballs, 1 1/2 to 2 inches in diameter.
Arrange the formed meatballs in a single layer on the baking dish, without touching each other.
Bake at 350 F until cooked through or when the internal temperature reaches 165 F, 25 to 30 minutes (see "Baking Time For Meatballs" section below).
While the meatballs are baking, prepare the sauce and toppings. Heat marinara sauce in a small saucepan and simmer for about 5 minutes, stirring frequently. Reduce heat to low and stir in cream until it forms a lovely orange hue. Keep warm over low heat while you wait for the meatballs.
Once the meatballs are done, transfer only the meatballs onto serving plates, leaving the grease in the baking dish.
Pour creamy tomato sauce over the meatballs, and top with parmesan cheese. Sprinkle parsley and crushed red pepper. Serve while hot.
