Hamburger Potato Casserole

I tried this recipe this past week. I really liked it. Mr. 31 ate it. He was very polite. But, to be fair, he's not really into casseroles. Maybe I shouldn't make so many...

Hamburger Potato Casserole
Adapted from a recipe on About.com

1 lb. ground beef
1 medium onion, chopped
3 medium potatoes, sliced
2 cups green beans (I use frozen)
1 (10.5 oz.) can of cream of mushrooms soup
1 cup cheddar cheese, shredded
1 tbs. garlic powder
salt and pepper to taste

1. Preheat oven to 350 degrees.

2. Brown ground beef and onion, seasoned with the garlic powder and salt and pepper to taste. Drain fat. Transfer ground beef mixture to a 9x13 pan or a 3 qt. casserole dish (whichever you'd like or have on hand).

3. Layer potatoes on top of the ground beef. Place green beans on top of potatoes (I used frozen and didn't even thaw them before I added them to the casserole).

4. Spread soup on the top. Season with salt and pepper to taste.

5. Place in oven and bake for 40-50 minutes. Take out of oven and sprinkle cheese over the top. Bake for an additional 5 minutes or until cheese is melted.
