preparation:

Brown the Ground Beef:

In a large skillet over medium-high heat, cook the ground beef until it’s browned and crumbly. Drain any excess grease.

Combine Ingredients:

Stir in the garlic salt, salt, and tomato sauce with the beef. Mix thoroughly and let it simmer for about 20 minutes. Once done, remove from heat and cover.

Prepare the Noodles:

Bring a large pot of salted water to a boil. Cook the egg noodles until they are al dente. Drain the noodles and rinse them with cold water to halt the cooking process.

Preheat and Prep the Dish:

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch casserole dish with cooking spray.

Mix Sour Cream Mixture:

In a bowl, blend together the diced onion, sour cream, and cream cheese until smooth.

Assemble the Casserole:

Spread half of the cooked noodles evenly in the bottom of the prepared casserole dish. Layer with half of the sour cream mixture, followed by half of the beef mixture. Repeat these layers with the remaining ingredients.

Add Cheese:

Sprinkle the shredded Cheddar cheese generously over the top of the casserole.

Bake:

Place the dish in the preheated oven and bake for about 25 minutes, or until the cheese is melted and bubbly.
