Turn on the oven and set it to 350°F (175°C). Apply some grease to a 9x13-inch baking dish to prevent sticking.
02 -
Use a large frying pan to crumble and brown the beef over medium heat. Stir occasionally while it cooks, then drain off the extra grease. Add the chopped onion and cook it for a couple of minutes until soft and tender.

In a mixing bowl, stir together the cream of mushroom soup, cream of chicken soup, sour cream, garlic powder, black pepper, and salt until smooth.
04 -
Take the cooked beef mixture and toss it into the bowl with the soups. Add the cooked egg noodles and peas (if you’re using them). Stir it all so the ingredients are evenly spread out.
05 -
Mix in 1 cup of cheddar cheese until it’s blended nicely throughout the casserole.
06 -
Pour everything from the bowl into the greased baking dish. Smooth out the top so it’s spread evenly.
07 -
Scatter the rest of the shredded cheddar on top. Then sprinkle on the crushed potato chips or breadcrumbs for a crispy finish.
08 -
Pop the dish into the oven and bake it for about 30-35 minutes. Watch for a bubbling casserole with a lightly browned top.
09 -
Let the casserole cool off for about 5 minutes before scooping it onto plates.
