Ingredients

1 pound ground beef
1 can (15 oz) green beans, drained
1 can (10.5 oz) cream of mushroom soup
½ cup milk
1 cup shredded cheddar cheese
1 cup French fried onions
1 teaspoon garlic powder
1 teaspoon onion powder
Salt and pepper, to taste

Instructions

1. Preheat the Oven

Set your oven to 350°F (175°C). Grease a 9×13-inch baking dish and set aside.

2. Cook the Ground Beef

In a large skillet over medium heat, brown the ground beef until no longer pink.
Break it up as it cooks, then drain off any excess fat.

3. Mix the Casserole Base

In a large mixing bowl, combine:

Cooked ground beef
Drained green beans
Cream of mushroom soup
Milk
Garlic powder
Onion powder
Salt and pepper

Stir until everything is fully blended.

4. Assemble the Casserole

Spoon the mixture into the greased baking dish and spread it evenly.

5. Add Cheese and Bake

Sprinkle shredded cheddar cheese evenly over the top.
Bake uncovered for 25 minutes, until the casserole is bubbling and the cheese has melted.

6. Add Crispy Onion Topping

Remove the casserole from the oven and top with French fried onions.
Return to the oven and bake an additional 5–10 minutes, or until the onions are golden and crisp.
