For the Casserole Base
- Ground Beef: We recommend using 85/15 ground beef for the perfect balance of flavor and leanness.
- Green Beans: Canned cut green beans are quick and easy, but you can use fresh or frozen if you prefer.
- Onion & Garlic: These aromatics build a deep, savory foundation for the entire dish.
For the Creamy Sauce
- Cream of Mushroom Soup: This is the classic, creamy binder that brings the casserole together.
- Milk: Adds richness and creates the perfect sauce consistency.
- Soy Sauce & Worcestershire Sauce: These provide a boost of umami and depth that complements the beef.
For the Topping
- French Fried Onions: A non-negotiable for that signature crispy, crunchy, and savory topping.
- Cheddar Cheese: Shredded cheddar cheese melts beautifully into the topping, adding a delicious, gooey layer of flavor.

How to Make Hamburger Green Bean Casserole Step-by-Step
Making this incredible casserole is a straightforward process. Follow these simple steps for a perfect result every time.
- Preheat and Prep: Start by preheating your oven to 350°F (175°C). While it heats, finely chop your onion and mince the garlic.
- Brown the Beef: In a large skillet or Dutch oven, cook the ground beef and chopped onion over medium-high heat until the beef is browned and the onion is soft. Drain off any excess grease. Stir in the minced garlic and cook for another minute until fragrant.
- Create the Sauce: Stir the cream of mushroom soup, milk, soy sauce, and Worcestershire sauce into the skillet with the ground beef. Season with black pepper.
- Combine Ingredients: Gently fold in the drained green beans and half of the french fried onions.
- Assemble the Casserole: Transfer the mixture to a 9×13 inch baking dish and spread it into an even layer.
- Add Toppings and Bake: Sprinkle the shredded cheddar cheese evenly over the top, followed by the remaining french fried onions. Bake for 25-30 minutes, or until the casserole is hot and bubbly. Let it rest for a few minutes before serving.
Tips for the Best Hamburger Green Bean Casserole
Want to elevate your casserole from great to unforgettable? Here are a few expert tips:
- Don’t Overmix: When you add the green beans, fold them in gently to keep them from breaking apart.
- Shred Your Own Cheese: For the best melt, buy a block of cheddar and shred it yourself. Pre-shredded cheeses often have anti-caking agents that can affect the texture.
- Let it Rest: Allowing the casserole to sit for 5-10 minutes after baking lets it set, making it easier to serve.

Can I Make This Ahead of Time?

Yes, you can. If using frozen green beans, thaw them first and pat them dry. If using fresh green beans, we recommend blanching them for 3-4 minutes in boiling water, then plunging them in ice water before adding them to the casserole.
Store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, you can bake individual portions in the oven at 350°F (175°C) until warmed through, or simply microwave until hot.
If you’re not a fan of cream of mushroom, you can use cream of chicken, cream of celery, or cheddar cheese soup as a substitute. You can also make a homemade cream sauce using butter, flour, milk, and mushrooms.
We recommend using a lean ground beef, like 85/15 or 90/10. This provides plenty of flavor without making the casserole overly greasy. Be sure to drain any excess fat after browning the beef.
