Ingredients

1 pound ground beef

1 can (10.5 ounces) condensed cream of mushroom soup
2 cups shredded cheddar cheese, divided
2 cups cooked egg noodles

Directions

1. Preheat your oven to 350°F and lightly grease a 2-quart casserole dish.

2. Cook the egg noodles according to the package directions if they are not already prepared, then drain and set aside.

3. In a large skillet over medium heat, cook the ground beef until browned and fully cooked, breaking it up with a spoon as it cooks. Drain off any excess grease.

4. Stir the cream of mushroom soup, cooked noodles, and 1 cup of the shredded cheddar cheese into the cooked beef until everything is evenly combined.

5. Spoon the mixture into the prepared casserole dish and spread it out evenly. Sprinkle the remaining 1 cup of cheddar cheese over the top.

6. Bake uncovered for 20 to 25 minutes, or until the casserole is hot and the cheese is melted, bubbly, and lightly golden. Let it rest for 5 minutes before serving.

Variations & Tips

Kid-Friendly Swap: If you have picky eaters, try using cream of chicken soup instead of cream of mushroom for a milder flavor and smoother texture that some kids prefer.

Add a Vegetable: Stir in 1 cup of cooked peas, corn, or sautéed mushrooms with the beef mixture if you want to stretch the casserole and add a little more color to the plate.

Make-Ahead Tip: Assemble the casserole up to a day in advance, cover, and refrigerate. When ready to bake, add a few extra minutes to the cooking time so it heats all the way through.

Cheese Tip: Sharp cheddar gives the casserole the best old-fashioned flavor, but a Colby-jack blend also melts beautifully and works well for families who like a slightly gentler cheese taste.

Leftover Tip: Leftovers reheat nicely for lunch the next day. Warm individual portions in the microwave or cover the dish and reheat in a low oven until hot.
