Preheat your oven to 350°F (175°C).
Cook the egg noodles according to package instructions. Drain and set aside.
In a skillet, cook the ground pork over medium heat until browned. Drain any excess fat.
Add the chopped onion and minced garlic to the skillet. Cook until the onion is translucent.
In a large mixing bowl, combine the cooked noodles, pork mixture, sour cream, cream of mushroom soup, milk, and half of the shredded cheddar cheese. Mix well.
Season with salt and pepper to taste.
Transfer the mixture to a baking dish. Sprinkle the remaining cheddar cheese on top.
Bake in the preheated oven for 30-40 minutes, or until the casserole is bubbly and the cheese is melted and golden brown.
Let it cool for a few minutes before serving. Enjoy!
