A hearty and flavorful casserole dish perfect for family dinners or gatherings.
Preheat your oven to 350°F (175°C).
Preheating ensures even cooking from the start.
Cook the egg noodles in a large pot of boiling salted water until al dente, then drain and set aside.
Avoid overcooking the noodles as they will continue to cook in the oven.
In a frying pan, brown the ground beef with the chopped onion until the beef is cooked through and the onion is soft. Drain any excess fat.
Breaking up the beef into small pieces helps it cook evenly.
In a large mixing bowl, combine the sour cream, peas, corn, mushrooms, salt, and pepper.
Mix gently to avoid breaking the vegetables.
Add the cooked beef and noodles to the bowl and mix until everything is evenly coated.
Ensure all ingredients are well combined for even flavor distribution.
Transfer the mixture to a greased casserole dish and spread it out evenly.
Greasing the dish prevents sticking and makes cleanup easier.
Sprinkle the shredded cheddar cheese evenly over the top.
For a golden crust, use a mix of cheeses.
Bake in the preheated oven for 30 minutes, or until the cheese is bubbly and golden.
Let the casserole rest for a few minutes before serving to set.
Serve warm and enjoy your delicious casserole!
Pair with a fresh salad for a complete meal.
