Cook the noodles for the lowest recommended amount of time on the package. They will finish cooking later in the oven, and you don't want them to over cook and turn mushy.
Drain the cooked noodles, and then run them under cold water, tossing, to stop cooking.
While the noodle are cooking, sautéed the ground beef in a large skillet over medium high heat- stirring & breaking it up as it cooks. When cooked through, drain the meat, and set aside.
In a large mixing bowl, stir together the condensed soups until evenly combined. Add in the half & half, onion, Worcestershire, garlic powder, and salt & pepper- stirring to evenly combine.
Now add the cooked meat and the noodles, stirring to evenly combine. Transfer the casserole mixture to a lightly greased 9x13" casserole dish. Use a spatula tp spread out the mixture evenly.
Sprinkle the mozzarella evenly out over top of the casserole. Then sprinkle the Parmesan. Bake the dish at 350 degrees for 25 minutes, or until heated through and the cheese has melted and begun to turn golden brown.
Let the mixture rest 1-2 minutes before scooping & serving. Enjoy!
