Preheat your oven to 350 degrees.
Spray a large baking sheet with non-stick cooking spray or line a baking sheet with parchment paper.
In a large Mixing bowl, Combine the hot sausage and ground beef. Mix with your hands until well combined. (You can use food preparation gloves for this process if that makes it more tolerable)
Add the rest of the ingredients. (Breadcrumbs, parmesan cheese, cream, eggs, parsley, minced garlic, onion powder, and salt.) Mix again until well combined.
To make the meatballs, roll about 1 ½ tablespoons of the meat mixture between your hands to form a ball. Place the meatballs on a greased baking sheet or a parchment-lined baking pan, about 2" apart. Repeat this process until you have formed all your meatballs.
Bake in a 350-degree oven for approx 25 minutes or until golden brown on the outside and the inside of the meatballs reach at least 145 degrees internally.
Take out of the oven and let sit for a couple minutes before adding the meatballs to a baked pasta dish, or sub sandwich. These can be cooled and then frozen to use at a later date. This recipe makes approx. 24 meatballs. Enjoy!
