This green bean casserole with hamburger is one of my husband Ken's favorite casseroles. I'm sure it is mostly because of the green beans. He can't get enough of them.
This dish works great with ground beef, ground pork, and ground turkey. We've tried it with all and sometimes even a mixture. Frankly, I use whatever I have in the house or my freezer to keep things simple.
This recipe is a great way to use fresh green beans from your garden but these days you can make it all year round!
I love these all-in-one meals or casseroles. Easy to make and easy to clean up!

- Cream of mushroom soup: Using canned soup makes this dish a breeze while giving it a delicious creamy texture.
- Crispy fried onions: Added to the top for crunchiness and pop of flavor.

- Soy sauce: Added to the creamy sauce for the casserole to give it a more savory flavor. You can also use Worcestershire sauce.
- Butter: Mixed into the mashed potatoes for richer flavor.
- Cream or milk: For the mashed potatoes so anything works but the more milk fat your dairy contains, the richer the flavor they will have.
- Parmesan cheese: Added to the mashed potatoes you can leave it out or swap it for another hard grating cheese like Romano or Asiago.
Substitutions and Variations
- Fresh Green Beans: If they aren't available you can use frozen instead.
- Russet Potatoes: Use yellow, white, or red potatoes instead to make the mashed potatoes.
- Mushroom Soup: Use another type of condensed soup such as cream of celery, cream of chicken, cream of asparagus, cream of potato, cream of onion, or cream of bacon.
- Crispy Fried Onions: Use crushed corn chips, tortilla chips, potato chips or nothing at all.
- Cream or Milk: Use sour cream instead.
- Spicy: Add a teaspoon of chili pepper flakes, jalapeno powder, smoked jalapeno powder, or chipotle powder to the ground beef mixture for a little heat.

Refrigerator: Store in an air-tight container for up to 4 days.
Freezer: Store in an air-tight container for up to 3 months.
Make Ahead: Layer all ingredients up to a day in advance, then refrigerate until ready to bake the dish. Remove the casserole from the fridge and let it sit on the counter for thirty minutes before baking.
Reheat: Bake at 350 for 15 to 20 minutes until heated through or heat individual portions in the microwave for 1-2 minutes.
- Chop the onion into small pieces for a better distribution of flavor throughout the casserole.
- Use fresh green beans instead of frozen or canned. They have more flavor and crunch.
- Grate your cheese rather than using pre-shredded varieties found in stores as these tend to have added ingredients that prevent melting properly during the baking process.
- Drain off any excess grease from cooking the ground meat before combining with other ingredients so they don’t make the dish greasy.
- Broil the top layer of cheese to brown slightly to give it a golden color.
No, you do not need to peel the potatoes before boiling them for this recipe. Just be sure to wash and scrub them well beforehand. After cooking you should easily be able to remove the peel if you want or leave them in for a more rustic mashed potato and more nutrition.
Yes, you can use canned green beans if desired but make sure that you drain them well. Also, reduce or omit any additional liquid in the recipe as there tends to be more moisture in canned vegetables than fresh or frozen ones.
Yes, you should brown the ground meat with diced onions until it is cooked through and drain off any excess fat before adding it to your casserole dish.
