Step 1

Cook the Beef & Vegetables:Heat a large skillet over medium heat. Add the ground beef and chopped onion. Cook until the beef is browned, breaking it apart with a spoon. Stir in the carrots, celery, and frozen peas, cooking for a few minutes until slightly softened.

Step 2

Prepare the Casserole Mixture:Add the cooked egg noodles to the skillet. Pour in the cream of mushroom soup and milk, stirring until everything is well combined. Mix in ½ cup of shredded cheddar cheese, stirring until melted into the mixture.

Step 3

Assemble & Bake:Transfer the mixture to a greased 9×13-inch baking dish, spreading it evenly. Sprinkle the remaining ½ cup of shredded cheddar cheese over the top. Bake in a preheated oven at 350°F (175°C) for 25-30 minutes, or until the cheese is golden and bubbly.

Step 4

Serve & Enjoy:Let the casserole cool for a few minutes before serving. Makes 6 servings—enjoy it on its own or pair with a fresh salad or crusty bread!
