Who knew my beloved takeout could be a casserole? This is a serious life hack!

Preheat your oven to 350°F (175°C).

In a large skillet over medium heat, add the sesame oil and sauté the onions until translucent, about 5 minutes.

Add the garlic and sauté for another minute until fragrant.

Add the ground beef to the skillet, cooking until browned, about 6-8 minutes. Drain any excess fat.

Stir in the mushrooms and cook until softened, about 4 minutes.

Add the soy sauce, oyster sauce, and black pepper. Mix well.

In a large mixing bowl, combine the cooked noodles, beef mixture, cream of mushroom soup, and half of the shredded cheddar cheese. Mix until evenly incorporated.

Pour the mixture into a greased 9×13 inch baking dish and spread it evenly.

Sprinkle the remaining cheddar cheese on top.

Bake in the preheated oven for 25-30 minutes, until bubbly and the cheese is golden brown.

Garnish with sliced green onions before serving.
