Ingredients You’ll Need
Serves 6–8
- 1 lb (450g) ground beef
- 2 cups uncooked egg noodles
- 1 cup sliced mushrooms (canned or fresh)
- 1 cup celery, diced
- 1 small onion, diced
- 1 can (10.5 oz) cream of mushroom soup

How to Make Grandma’s Casserole
Step 1: Prep and Cook the Noodles
Bring a large pot of salted water to boil and cook egg noodles according to package directions. Drain and set aside while preparing the sauce and beef mixture.
Step 2: Cook the Ground Beef and Vegetables
In a large skillet over medium heat, brown the ground beef until fully cooked. Drain excess fat. Add diced onion, celery, and mushrooms, cooking until softened. Stir in garlic powder, onion powder, salt, and black pepper.
Step 3: Make the Sauce
In a bowl, mix cream of mushroom soup, soy sauce, and milk until smooth. Pour the sauce into the beef and vegetable mixture, stirring to combine. Remove from heat.
Step 4: Assemble the Casserole
Preheat oven to 350°F (175°C). In a greased 9×13-inch baking dish, layer cooked noodles and beef mixture. Spread evenly, then sprinkle the top with canned chow mein noodles for a crunchy finish.
Step 5: Bake and Serve
Bake uncovered for 25–30 minutes, until the casserole is bubbly and the topping is lightly golden. Let cool for 5 minutes before serving.
Tips for Extra Flavor
- Add a splash of Worcestershire sauce for deeper umami.
- Toss in frozen peas or shredded carrots for color and nutrition.
- Swap cream of mushroom with cream of chicken or celery soup for a different flavor twist.
- For extra crunch, broil the casserole for 1–2 minutes at the end.
