• 1 pound ground beef – Lean or regular, depending on your preference.
• 8 ounces egg noodles – Wide or medium noodles work best.
• 1 can (10.5 ounces) cream of mushroom soup – For a creamy, savory base.
• 1 cup sour cream – Adds tanginess and richness.
• 2 cups shredded cheddar cheese – Sharp cheddar brings bold flavor.

How to Make Cheesy Beef and Noodle Casserole with Crispy French Onions

Follow these easy steps to make your casserole perfectly creamy and golden every time.

Step 1: Cook the noodles

Boil the egg noodles in salted water until al dente, about 1 minute less than the package recommends. Drain and set aside.

Step 2: Brown the beef

In a large skillet over medium-high heat, cook the ground beef until no longer pink. Drain excess grease. Add onion powder, garlic powder, salt, and pepper, stirring to season the meat evenly.

Step 3: Combine ingredients

In a large mixing bowl, combine the cooked beef, egg noodles, cream of mushroom soup, sour cream, and 1 cup of shredded cheddar cheese. Stir until everything is well coated in the creamy sauce.

Step 4: Assemble the casserole

Transfer the mixture into a greased 9×13-inch baking dish. Spread it out evenly and sprinkle the remaining cheese on top.

Step 5: Bake

Bake in a preheated oven at 350°F (175°C) for about 20 minutes, until hot and bubbly.

Step 6: Add the crispy topping

Remove from the oven, sprinkle the crispy French onions evenly over the top, and return to the oven for another 5–7 minutes until the onions are golden brown and crunchy.

Step 7: Serve and enjoy

Let the casserole rest for 5 minutes before serving. This helps the sauce thicken slightly and makes for easier slicing.

Tips for the Best Casserole Texture and Flavor

• Use sharp cheddar for a stronger, richer cheese flavor.
• Add a splash of milk to the sauce if you prefer a creamier texture.
• Mix in vegetables like peas, carrots, or mushrooms for extra nutrients.
• Avoid overbaking; the casserole should stay moist and creamy.
• Combine breadcrumbs and French onions for an even crunchier topping.
