To make these meatballs, start by preheating your oven to 400ºF.
Next, grease a large baking sheet with cooking spray and set aside.
Then, add all of the meatball ingredients to a bowl and use your hands to work them together, until they're fully combined.
Use a cookie scoop and scoop out some of the meat, forming it into a 2-inch meatball. Repeat until all of the meat has been formed into meatballs, and line them up on the baking sheet. You should get approximately 28-30 small meatballs.
Transfer the tray to the oven and bake the meatballs for 15-20 minutes, or until they are browned and cooked through.
While the meatballs are baking, prepare the sauce.
Heat a large skillet, on the stove, over medium heat, and add in the butter. Once the butter is melted and bubbling, add the flour and whisk until there are no clumps.
Then, add in the beef broth, dijon mustard, kosher salt, nutmeg, allspice and heavy cream, and continue to whisk until the sauce is smooth.
Once the meatballs are done, remove them from the oven and add them to the pan with the sauce.
Then, place the cover on the pan and allow the meatballs to cook for 10 minutes.
While they're cooking, prepare the egg noodles according to the package instructions.
Once the noodles are done, drain the water from them and coat them well, with butter.
Finally, transfer the meatballs and sauce to the noodles, then garnish with chopped parsley.
Once they're done, serve and enjoy!
