Ingredients You’ll Need
The beauty of Hamburger Green Bean Casserole is in its sheer simplicity—basic pantry staples work together to build layer upon layer of flavor, texture, and color. Each ingredient has a purpose, making every bite satisfying and delicious.
- 1 pound ground beef: The hearty base of the casserole, providing depth and that signature savory flavor.
- 1 can (15 oz) green beans, drained: Adds color, subtle sweetness, and a burst of freshness—canned, fresh, or frozen all work here.
- 1 can (10.5 oz) cream of mushroom soup: The creamy foundation that ties the filling together and creates a luscious sauce.
- ½ cup milk: Helps thin the soup, ensuring the casserole stays moist without being too dense.
- 1 cup shredded cheddar cheese: Melts into bubbly, cheesy goodness that makes every forkful irresistible.
- 1 cup French fried onions: The signature crispy topping, bringing bold flavor and incredible crunch.
- 1 teaspoon garlic powder: Adds a warm, savory note that complements both the beef and the veggies.
- 1 teaspoon onion powder: Enhances the flavors already in play for a well-rounded, comforting taste.
- Salt and pepper, to taste: Essential for seasoning and balancing every single bite.
How to Make Hamburger Green Bean Casserole
Step 1: Preheat the Oven
Get your oven going at 350°F (175°C). Starting with a hot oven ensures the casserole bakes evenly, with a perfectly melted cheesy top and golden crisp finish.
Step 2: Brown the Ground Beef
Heat a large skillet over medium warmth, add your ground beef, and break it apart while it cooks. Stir and sauté until the meat is thoroughly browned and no pink remains—about 6-8 minutes. Don’t forget to drain the excess fat for a creamy, not greasy, casserole.
Step 3: Mix the Filling
In a large bowl, combine your cooked beef, green beans, cream of mushroom soup, milk, garlic powder, onion powder, and a sprinkle of salt and pepper. Stir until everything is coated in a creamy, savory sauce—the scents alone will make your mouth water!
Step 4: Assemble the Casserole
Lightly grease a 9×13 inch baking dish so nothing sticks. Spread the hearty mixture in the dish, making sure every inch is filled. Layer the shredded cheddar cheese on top to guarantee a gooey, golden cap with every serving.
Step 5: Bake and Top with French Fried Onions
Pop the casserole into your preheated oven and bake for 25 minutes, or until everything is bubbling and the cheese is beautifully melted. Pull it out carefully, top with the French fried onions, and return to the oven for another 5-10 minutes—just long enough to toast the onions to crispy perfection. Let it cool for a few minutes before serving so it sets up and scoops out like a dream.
How to Serve Hamburger Green Bean Casserole

Garnishes
For an effortless flourish, sprinkle freshly chopped parsley or chives over your Hamburger Green Bean Casserole just before serving. The pop of green isn’t just pretty—it brings a light herbaceous note that brightens the whole dish.
Side Dishes
This casserole is a complete meal on its own but shines even brighter with a few simple sides. Think a crisp green salad, creamy mashed potatoes, or a slice of crusty bread to soak up every bit of that savory sauce. Even some pickles or tangy coleslaw can balance the richness.
Creative Ways to Present
Individual ramekins are a fun way to serve Hamburger Green Bean Casserole for company, making each person feel special. If you’re feeding a crowd, you can double the recipe and use a larger baking dish. For potlucks or family dinners, serve straight from the dish with a bold serving spoon—everyone will dive right in!
Make Ahead and Storage
Storing Leftovers
Leftover Hamburger Green Bean Casserole keeps beautifully. Simply cover the baking dish or scoop into an airtight container and refrigerate for up to three days—the flavors will deepen and meld, making the next meal even more delicious.
Freezing
If you want to stash some away for a future busy night, assemble the casserole right up to the point of adding the fried onions. Wrap tightly in plastic wrap and foil, freeze for up to two months, and wait to add the onions until just before finishing in the oven.
Reheating
To reheat, let the casserole come to room temperature if possible. Warm in a 350°F oven until hot and bubbling, or microwave individual servings for a quick, satisfying lunch. Add a fresh sprinkle of fried onions after reheating if you love them especially crispy.
FAQs

Cheddar is the classic choice, but feel free to experiment with Monterey Jack, Colby, or Swiss cheese for new flavor twists. Mixing cheeses can also deepen the overall cheesiness!
