The 4-Star Ingredients

This recipe proves that you do not need a long ingredient list to create something delicious. Here is what you will need:

Wide egg noodles – 8 ounces (about 4 cups dry). Egg noodles are the perfect pasta for this casserole. Their wide, flat shape holds the creamy sauce beautifully and provides a tender, satisfying texture.

Hard boiled eggs – 6, peeled and chopped. Hard boiled eggs add protein, richness, and a hearty texture. They are the star of this nostalgic casserole.

Condensed cream of mushroom soup – 2 cans (10.5 ounces each). Cream of mushroom soup creates the rich, creamy base of the sauce. It adds savory depth and a velvety texture.

Shredded mild cheddar cheese – 2 cups, divided. Cheddar adds a bold, tangy, savory flavor and creates a beautiful, melted, golden topping.

That is it. Four ingredients. No onions. No garlic. No complicated steps. Just honest, delicious ingredients that come together beautifully.

Step-by-Step Instructions

Step 1: Preheat and Prep

Step 5: Top with Cheese

Sprinkle the remaining ½ cup of shredded cheddar cheese evenly over the top.

Step 6: Bake

Step 7: Rest and Serve

Let the casserole rest for 5 to 10 minutes before serving.
