Description

This Homemade French Onion Beef Casserole is the ultimate comfort dish featuring savory ground beef, creamy mushroom and onion flavors, tender egg noodles, and a golden layer of crispy fried onions. It’s hearty, family-friendly, and makes excellent leftovers too.


Ingredients

1 pound ground beef

12 ounces egg noodles

1 can (10.5 ounces) French onion soup

1 can (10.5 ounces) cream of mushroom soup

1 cup sour cream

2 cups shredded mozzarella cheese

1 ½ cups crispy fried onions

1 teaspoon salt

½ teaspoon black pepper


Instructions

1. Preheat oven to 350°F (175°C).

2. In a large skillet over medium heat, cook ground beef with salt and pepper until browned. Drain excess fat.

3. Boil egg noodles in a large pot according to package instructions. Drain and set aside.

4. In a large mixing bowl, combine browned beef, French onion soup, cream of mushroom soup, sour cream, and 1 cup of shredded mozzarella cheese. Stir until well mixed.

5. Fold in the cooked noodles until evenly coated.

6. Transfer the mixture into a greased 9×13-inch baking dish. Spread evenly.

7. Top with remaining 1 cup mozzarella cheese.

8. Bake uncovered for 25–30 minutes until hot and bubbly.

9. Remove from oven and sprinkle crispy fried onions over the top.

10. Return to oven and bake an additional 5–10 minutes until onions are golden and crispy.

11. Let rest for 5 minutes before serving.

Notes

Don’t add the crispy fried onions until the last 10 minutes of baking—this keeps them golden and crunchy.

For added richness, try using a blend of mozzarella and Gruyère cheese.

You can prep the casserole the night before—just wait to bake until ready to serve.
