Hamburger Green Bean Casserole
Ingredients
- 1 pound lean ground beef
- 1 yellow onion finely chopped
- 2 cloves garlic minced
- 1 can condensed cream of mushroom soup 10.5-ounce
- 1/2 cup whole milk
- 1/2 cup sour cream
- 1/4 tsp black pepper
- 2 cans cut green beans 14.5-ounce, drained
- 1 1/2 cups French fried onions
Method
- Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.
- In a large skillet over medium-high heat, cook the ground beef and chopped onion for 6 to 8 minutes, breaking the meat up with a spoon until it is browned and the onion is soft and translucent. Stir in the minced garlic and cook for 1 minute more until fragrant, then drain any excess grease from the skillet.
- Add the condensed cream of mushroom soup, whole milk, sour cream, and black pepper to the beef mixture. Stir with a wooden spoon until everything is fully combined and the sauce is smooth.
- Gently fold the drained green beans into the beef and sauce mixture until they are evenly coated, then transfer the entire mixture to the prepared baking dish and spread it into an even layer.
- Bake the casserole uncovered in the preheated oven for 25 minutes. The edges should be bubbling.
- Remove the casserole from the oven and carefully sprinkle the French fried onions in an even layer over the top. Return it to the oven and bake for 5 more minutes, just until the onions are golden brown and crispy.

Private Notes
Let’s Get This Easy Casserole Started
I love recipes that don’t tie me to the stove all evening. You’ll only need about 15 minutes of hands on prep work for this easy weeknight meal with green beans.
Then, the oven does most of the heavy lifting for about 35 minutes. In under an hour, this Hamburger Green Bean Casserole is ready to feed your whole family, making it the perfect weeknight dinner casserole.
Thoughtful Tips for a Sugar Conscious Kitchen
If you are sugar conscious or managing your glycemic intake, a few small tweaks can make this recipe work for you. I always believe in adapting recipes to fit our lives, not the other way around.
Consider using a low sodium cream of mushroom soup to better control ingredients. You can also swap the sour cream for plain Greek yogurt, which is a fantastic natural option with less sugar and more protein.
My Favorite Pro Tips for Perfect Results
I’ve made this Hamburger Green Bean Casserole more times than I can count, and I’ve learned a thing or two. First, always drain your green beans thoroughly to keep the sauce from getting watery.
For a flavor twist, try adding a pinch of smoked paprika to the beef while it cooks. If you love cheesy recipes, a handful of shredded cheddar stirred into the mixture is divine. Check out my cheeseburger pasta for more cheesy dinner inspiration.
Let the casserole sit for five minutes after baking so the sauce can set beautifully. For a fantastic side, my sweet potato casserole pairs wonderfully with these savory flavors.
The Wonderful Nutrition in Every Cozy Bite
This hearty baked dinner with ground beef is more than just comforting, it’s nourishing. The lean beef provides a great source of protein and iron to keep you feeling full and satisfied.
Green beans add a wonderful boost of fiber and essential vitamins to your plate. For more ideas on building a balanced plate, you can explore the USDA food safety guidelines and nutritional resources. Discover other wholesome meals like my black bean burger for another protein packed option.
How to Lighten Up Your Green Bean Bake
You can absolutely make a lighter version of this family favorite without losing an ounce of flavor. I often use 93% lean ground beef and find it works just as well in this savory casserole with sour cream.
Try swapping the sour cream for plain, non fat Greek yogurt to cut down on fat. You could even use a low fat condensed soup, though I find the classic version gives the best texture. For other comforting yet lighter ideas, my chicken casserole is a great choice. You might also enjoy the flavors in this hamburger potato casserole which can be adapted similarly.
How to Serve This Classic Family Supper
I love serving this casserole straight from the oven, with the fried onions still crackling. It reminds me of those relaxed Sunday dinners at my grandma’s house, where the table was always full of laughter and simple, good food.
It’s fantastic alongside a simple green salad or some buttery dinner rolls for soaking up the creamy sauce. For a full feast, it pairs beautifully with my potato squash casserole or a scoop of monster burgers for the ultimate comfort food spread.
Common Mistakes to Avoid for the Best Casserole
The most common hiccup is forgetting to drain the ground beef properly, which can make the final dish greasy. Simply tilt your skillet and spoon out the excess fat after browning for a perfect texture.
Another mistake is adding the French fried onions too early, causing them to lose their signature crunch. Always sprinkle them on during the last five minutes of baking. For more tips on perfecting ground beef dishes, my best burger recipe has great guidance. You can also see a different approach in this traditional tomato soup version.
Finally, avoid overbaking, as it can cause the green beans to become too soft. Pull it out when the edges are bubbling happily and the top is golden.
How to Store and Savor Your Leftovers
I actually think the flavors of this casserole marry even more the next day. I store any leftovers in an airtight container in the fridge, and they reheat beautifully for lunch.
To reheat, pop a portion in the oven at 350°F until warm to keep the topping crispy. For more make ahead ideas, check out my breakfast casserole. You can also find inspiration in my bean salad recipe for using any extra green beans you might have.
