How to Make Hamburger Green Bean Casserole
-
Preheat your oven to 350°F (175°C). This sets the stage for the casserole to bake perfectly and become heavenly, ensuring it’s ready to melt that cheese wonderfully.
-
Brown the ground beef in a large skillet over medium heat. Use a spatula to break it up as it cooks until it’s no longer pink, about 6-8 minutes. Once done, drain any excess fat to keep it light.
-
Mix the cooked ground beef with the drained green beans, cream of mushroom soup, milk, garlic powder, onion powder, salt, and pepper in a large mixing bowl. Stir until everything is combined smoothly, creating a luscious filling.
-
Transfer the mixture into a greased 9×13 inch baking dish. Spread it evenly so every bite is filled with that flavorful goodness you just created.
-
Sprinkle the shredded cheddar cheese generously over the top. This will create a delightful, melty layer as it cooks, enhancing the casserole’s richness.
-
Bake for 25 minutes, or until it’s bubbly and the cheese melts to perfection. You’ll know it’s ready when you see those lovely golden edges.
-
Remove from the oven and top with French fried onions. Bake an additional 5–10 minutes until they are golden brown and crisp, providing that wonderful crunch we adore.
Optional: Serve with a sprinkle of fresh herbs for an added touch of freshness.

Hamburger Green Bean Casserole Recipe FAQs
How do I choose the right green beans?
Absolutely! When it comes to selecting green beans, look for ones that are firm and crisp. Avoid those with dark spots or those that appear limp. If you’re using frozen beans, check for high-quality brands with no added sauces or flavors for the best results.
How should I store leftover Hamburger Green Bean Casserole?
Very good question! Store any leftover casserole in an airtight container in the fridge for up to 3 days. To preserve freshness, allow it to cool completely before sealing it. When reheating, I recommend using the oven for an evenly warmed dish—just pop it back in at 350°F (175°C) for about 15-20 minutes until hot.
Can I freeze Hamburger Green Bean Casserole?
Absolutely, freezing is a great option! If you want to prep ahead, wrap the uncooked casserole tightly in plastic wrap followed by aluminum foil, and stash it in the freezer—up to 3 months is ideal. When you’re ready to enjoy, thaw it overnight in the fridge, then bake at 350°F (175°C) for 30-40 minutes, until it’s heated all the way through.
What if my casserole is too watery after baking?
A common hiccup! If your casserole turns out watery, it may be due to the green beans or the amount of milk used. For future preparations, you could drain the green beans well and reduce the milk slightly, or even add a tablespoon of cornstarch mixed with water to thicken the filling.
Is this recipe suitable for dietary restrictions?
Great question! The Hamburger Green Bean Casserole contains gluten and dairy due to the cream of mushroom soup and cheese. If allergies are a concern, consider using gluten-free soup options and dairy-free cheese alternatives. For pets, ensure no leftovers are offered to them, as onions can be harmful to dogs.
What can I substitute for ground beef in this casserole?
Very easy! If you’re looking for alternatives, ground turkey or chicken would work wonderfully, lending a milder flavor. For a vegetarian version, try using lentils or black beans for protein and texture. Just ensure you season appropriately to keep the heartiness of the casserole intact.
