This Hamburger Green Bean Casserole is pure comfort on a plate My kids call it the cozy dinner because the aroma fills the house and everyone races to the table It is the one dish I reach for when schedules are hectic and I want a meal everyone will eat with a smile The whole thing comes together quickly with easy to find staples and a satisfying savory crunch on top
I learned about this casserole from a neighbor potluck as a new mom and now it has become the dish everyone asks for at our family reunions
Ingredients
- Ground beef or ground turkey: choose lean for less grease and lots of flavor
- Large onion, diced: go for yellow or sweet for best flavor and a soft bite
- Garlic cloves, minced: always use fresh for aromatic depth
- Green beans: canned, fresh or frozen fresh is crisp and vibrant but canned offers classic comfort texture
- Cream of mushroom soup: buy a good quality can or use homemade for richer flavor
- Milk or beef broth: whole milk makes it creamy while broth brings umami notes
- Sharp cheddar cheese, shredded: sharpness cuts through the rich pie and pulls the casserole together
- French fried onions: these make the topping so always pick a fresh crispy batch for crunch
- Worcestershire sauce: adds a meaty savoriness that amps up the burger vibe
- Black pepper and paprika: for spice and gentle warmth paprika is optional but gives a little color
- Salt: taste as you go since different soups and cheeses add different levels of saltiness
- Optional mushrooms: fresh sautéed mushrooms layer in earthy flavor I am a fan of using cremini
- Ketchup or mustard: just a dab brings tangy burger essence
- Cooked bacon crumbles: sprinkle on top for an extra smoky treat that rivals your favorite bacon cheeseburger
Instructions
- Brown the Meat and Aromatics:
- Cook ground beef onion and garlic in a large skillet over medium heat Stir and break up the beef while cooking for about 8 minutes until the meat is thoroughly browned and the onions turn soft Gold around the onions is perfect Drain any extra fat to keep things from getting greasy
- Mix the Casserole Filling:
- Add green beans either drained canned or thawed frozen along with cream of mushroom soup milk Worcestershire sauce black pepper and paprika Stir gently but well so everything gets evenly coated and the soup fully blends in The mixture should look creamy and lush with pops of green beans throughout
- Transfer and Layer:
- Spoon this mixture into a greased nine by thirteen inch baking dish Then sprinkle the shredded cheddar cheese all over Try to get cheese in every corner Add the layer of French fried onions on top for that classic crisp finish
- Bake It Through:
- Place the dish uncovered in a three hundred fifty degree oven Set a timer for twenty to twenty five minutes Look for bubbling at the edges and a golden brown crispy topping The cheese should melt and the onions will become even crunchier
- Rest and Serve:
- Let the casserole rest for five minutes before scooping This helps it set and makes serving easier Trust me it stays hot

The sharp cheddar is my secret to getting my picky eater excited about green beans I still remember the first time my oldest asked for seconds and that made me a forever fan of this casserole
