How to Make Hamburger Green Bean Casserole
Preheat the Oven
Set your oven to 350°F or 175°C so it is ready when the casserole is assembled.
Brown the Ground Beef
In a skillet over medium heat, cook the ground beef until no pink remains. Break it apart with a wooden spoon for even cooking. Drain any excess fat to keep the casserole from becoming greasy.
Mix the Filling
In a large mixing bowl, combine the cooked beef with green beans, cream of mushroom soup, milk, garlic powder, onion powder, and a pinch of salt and pepper. Stir until everything is evenly coated.
Assemble the Casserole
Lightly grease a baking dish and spread the beef mixture evenly inside. Sprinkle the shredded cheddar cheese over the top.
Bake and Finish
Place the dish in the preheated oven and bake for 25 minutes. Remove from the oven, top with French fried onions, and return to bake for an additional 5 to 10 minutes until the onions are golden brown.
Notes
Drain the ground beef thoroughly after browning for the best texture.
Avoid overbaking once the fried onions are added to prevent burning.
Double the fried onions if you want extra crunch.
Taste and adjust the seasoning of the filling before baking.
For a fresh finish, sprinkle chopped parsley on top before serving.
How to Serve Hamburger Green Bean Casserole
Hamburger green bean casserole pairs beautifully with simple sides that balance its richness. Serve it alongside crusty bread to soak up the creamy sauce or with a crisp garden salad for freshness. Mashed potatoes or buttered egg noodles also make an excellent base for this dish. For a holiday table, you can plate it in smaller portions and offer it as part of a larger buffet.
How to Perfect Hamburger Green Bean Casserole
The secret to a memorable casserole is balance. Keep the beef to bean ratio even so every forkful delivers both textures. Make sure your sauce is creamy by draining beans well and measuring milk accurately. If you prefer a richer flavor, add a splash of Worcestershire sauce or a pinch of smoked paprika before baking.
Common Mistakes to Avoid
Not draining ground beef will cause the casserole to be greasy.
Cooking the fried onions too long will make them bitter.
Skipping seasoning adjustments can lead to a bland filling.
Storage and Reheating Instructions
Store leftover hamburger green bean casserole in an airtight container in the refrigerator for up to four days. For longer storage, freeze for up to two months. Reheat in the oven at 350°F, covering the dish for the first part of heating and uncovering for the last five minutes to re-crisp the topping.
