Optional finishing touches that do not technically add to the three-ingredient count: a generous layer of shredded sharp cheddar cheese spread over the top of the casserole during the last 10 minutes of baking melts into a golden, bubbly crust that makes the dish considerably more visually appealing and adds a pleasant saltiness. A pinch of black pepper and a small handful of frozen peas stirred into the gravy-broth mixture before pouring adds color and a vegetable element. A tablespoon of Worcestershire sauce added to the liquid deepens the savory quality noticeably.
Instructions
Step 1: Preheat and Prepare the Dish
Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Lightly spray a 9-by-13-inch baking dish or a similarly sized casserole dish with non-stick cooking spray. The size of the dish matters here: a dish that is too small will cause the noodles to pile up too thickly and cook unevenly, while a dish that is too large may cause the liquid to evaporate before the noodles have fully cooked. A standard 9-by-13-inch dish is the right size for this quantity of ingredients.
