Ingredients

• 1 pound ground beef
• 1 large yellow onion, finely chopped
• 12 ounces egg noodles
• 1 cup beef broth
• 1 packet French onion soup mix
• 1 cup sour cream
• 1 cup shredded mozzarella cheese
• 1 cup shredded cheddar cheese
• 1 teaspoon garlic powder
• 0.5 teaspoon black pepper
• 2 tablespoons butter
• 2 tablespoons fresh parsley, chopped (optional garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set aside.

Step 2

Cook the egg noodles according to the package instructions until al dente. Drain and set aside.

Step 3

In a large skillet, melt the butter over medium heat. Add the chopped onion and cook until softened and golden brown, about 5-7 minutes.

Step 4

Add the ground beef to the skillet, breaking it up with a spatula, and cook until browned and fully cooked, about 6-8 minutes. Drain any excess grease.

Step 5

Stir the French onion soup mix, beef broth, garlic powder, and black pepper into the skillet with the beef. Let the mixture simmer for 2-3 minutes to combine the flavors.

Step 6

Remove the skillet from heat and stir in the sour cream until fully incorporated.

Step 7

In a large mixing bowl, combine the cooked egg noodles and the beef mixture. Stir until evenly coated.

Step 8

Transfer the noodle and beef mixture into the prepared baking dish. Spread it out in an even layer.

Step 9

Sprinkle the shredded mozzarella cheese and cheddar cheese evenly over the top of the casserole.

Step 10

Bake in the preheated oven for 15-20 minutes, or until the cheese is melted and bubbly.

Step 11

Remove the casserole from the oven and let it rest for 5 minutes. Garnish with chopped parsley, if desired, before serving.
