This comforting hamburger green bean casserole is the kind of cozy dinner that brings everyone to the table. Rich beef mingles with tender green beans and creamy sauce, all tucked beneath a golden crown of crispy onions. It has become a go to for my family on chilly nights when we crave something hearty yet simple.
I first made this casserole for a busy school night and my kids now ask for it almost every week because of its cheesy flavor and crunchy topping.
Ingredients
- Ground beef: Choose lean beef for less grease and make sure to brown until no pink remains
- Canned green beans: Drained well as this keeps the casserole from turning watery Fresh or frozen can work if blanched and drained thoroughly
- Cream of mushroom soup: The creamy base that holds it all together Choose a soup with real mushrooms for deeper flavor
- Milk: Adds creaminess Whole milk creates the richest texture but any milk will do
- Shredded cheddar cheese: Brings meltiness and hearty flavor Opt for sharp cheddar and grate your own for the best melting
- Garlic powder: A quick way to get savory flavor without peeling garlic
- Onion powder: Deepens the overall savoriness Choose a fresh jar for bold flavor
- Salt: Essential for rounding out all the flavors Use kosher salt for more control
- Black pepper: Adds just the right amount of warmth and spice Freshly ground is best
- Crispy fried onions: The crisp layer on top adds crunch and that iconic flavor Use a fresh can for optimal crispiness
Step by Step Instructions
- Brown the Beef:
- Cook ground beef in a skillet over medium heat breaking up any large pieces with a spoon Continue until browned with no pink left and drain well to keep the casserole from being greasy
- Mix the Filling:
- Stir together the cooked beef green beans cream of mushroom soup milk cheddar cheese garlic powder onion powder salt and black pepper in a large bowl mixing until fully combined This is where flavors come together so do not skimp on seasoning
- Layer and Bake:
- Transfer the mixture into a greased baking dish and smooth the top Bake uncovered at three hundred fifty degrees for twenty five minutes This helps everything bubble and mingle without drying out
- Add Crispy Onion Topping:
- Carefully sprinkle crispy fried onions evenly over the hot casserole Then return to the oven for five to ten more minutes until the onions are golden and the edges are bubbling
- Rest Before Serving:
- Let the casserole sit for about five minutes before serving This thickens up the sauce so portions hold together on the plate

One of my favorite parts of this recipe is how the crispy fried onions bring crunch and a sense of nostalgia My mom used them on almost every holiday casserole and now my own kids beg for extra topping when we make this together
