Ingredients Needed to Make Hamburger Green Bean Casserole

• 1 lb ground beef
• 1 can (10.5 oz) cream of mushroom soup
• ½ cup sour cream

• ½ teaspoon black pepper
• 4 cups cooked green beans, drained (fresh or frozen both work)

Instructions to Make Hamburger Green Bean Casserole

Making Hamburger Green Bean Casserole is a breeze when you follow this step by step breakdown. Whether you’re new to cooking casseroles or just need dinner on the table fast, these easy-to-follow directions will have your kitchen smelling like comfort in no time.

Step 1: Brown the Ground Beef

Start by heating a large skillet over medium heat. Add 1 pound of ground beef, breaking it apart with a wooden spoon as it cooks. You want to brown it evenly until there’s no pink left—this usually takes about 6–8 minutes. If you’re looking to add a little flavor boost, a splash of Worcestershire sauce or even soy sauce while it browns can work wonders. Drain off any excess fat once it’s fully cooked. If you’re exploring leaner options, consider ground turkey or plant-based crumbles as a substitute (check out our Healthy Chicken Pot Pie Soup for more lightened-up comfort food ideas).

Step 2: Make the Creamy Base

In a large mixing bowl, combine one 10.5 oz can of cream of mushroom soup, ½ cup sour cream, 1 teaspoon garlic powder, and ½ teaspoon black pepper. Stir it all together until the texture is smooth and creamy. This is your casserole’s cozy core—it brings everything together. For a dairy-free option, go for a plant-based sour cream and mushroom soup combo. You can find tips on substitutes in our Creamy Roasted Garlic Tomato Soup if you’re experimenting with alternatives.

Step 3: Add the Green Beans and Beef

Next, fold 4 cups of cooked, drained green beans into the creamy base. Then add your browned ground beef. Stir gently but thoroughly so every bean and beefy bite gets coated in that luscious sauce. If you’re using frozen green beans, make sure they’re fully cooked and well-drained first. Need help cooking fresh green beans? Our Homemade Green Bean Casserole walks you through prepping them perfectly.

Step 4: Transfer to Baking Dish

Pour the mixture into a 9×13-inch baking dish, spreading it out evenly with a spatula. This is where it all comes together. You want an even layer so every bite has that perfect balance of beef, beans, and sauce. Optional but highly recommended: sprinkle 1 cup of shredded cheddar cheese over the top before the crispy onion layer. The cheese melts into gooey goodness that adds richness without overpowering the dish.

Step 5: Top with Crispy Fried Onions

Now for the crown jewel: take 1 ⅓ cups of crispy fried onions and scatter them generously over the top of the casserole. This is the layer that gives that crunchy, crave-worthy finish. Want to double the crunch factor? Mix half of the onions into the casserole mixture before baking, and reserve the rest for the top—like we do in our French Onion Green Bean Casserole.

Step 6: Bake Until Bubbly and Golden

Slide your casserole into a preheated oven at 350°F (175°C) and bake for 25 to 30 minutes. You’ll know it’s done when the edges are bubbling and the onions are golden and crisp. This is the moment your house starts to smell like magic—and your people start hovering in the kitchen, wondering when dinner’s ready.

Step 7: Cool Slightly, Then Serve

When it comes out of the oven, give it 5–10 minutes to cool slightly. This helps the sauce thicken a bit and makes it easier to slice and serve. Plus, nobody wants a tongue burn from molten mushroom sauce (we’ve all been there). Serve with a simple salad or buttery rolls—or go full cozy and pair it with Roasted Tomato Basil Soup for the ultimate comfort meal combo.

What to Serve with Hamburger Green Bean Casserole

Hamburger Green Bean Casserole is a meal in itself, but if you’re feeling fancy, it plays well with others. A simple side salad adds freshness, or you can throw some homemade dinner rolls on the table for mopping up any creamy bits left behind. Garlic bread? Always a yes. It also pairs beautifully with roasted root veggies or buttery mashed potatoes if you’re going all-out comfort mode. And if you’re meal prepping, try it alongside Pumpkin Chicken Chili for a comforting fall dinner duo.

Key Tips for Making Hamburger Green Bean Casserole

Want to avoid a bland casserole? Don’t skip seasoning the beef. A dash of Worcestershire or soy sauce while it cooks adds that “oomph.” If you’re using fresh green beans, give them a quick steam or blanch beforehand so they’re tender and not chewy. You can swap sour cream with Greek yogurt for a slightly lighter touch. Cheese? Totally optional—but honestly, it adds a lovely melt factor. And here’s a hot tip: add half the fried onions into the mixture before baking, then the rest on top to double down on that crunch.

Storage and Reheating Tips for Hamburger Green Bean Casserole

This casserole keeps like a champ. Store leftovers in an airtight container in the fridge for up to 4 days. To reheat, the microwave works in a pinch (think: lunch at work), but the oven is best if you want to revive that crispy onion topping. Just cover with foil and warm at 350°F for about 15 minutes, then uncover for 5 more to crisp it back up. You can also freeze it—yes, even with the onions! Wrap tightly, freeze for up to 2 months, and reheat straight from frozen (add 10–15 minutes to the cook time). Great for batch cooking or prepping ahead for busy weeks.

FAQs

Can I use frozen green beans?
Absolutely—just cook and drain them first so your casserole isn’t watery.

Is there a way to make this dairy-free?
Yep! Use a dairy-free cream of mushroom soup and swap sour cream with a plant-based version. Skip the cheese or use dairy-free shreds.

Can I prep this ahead?
Totally. Assemble it, cover, and refrigerate for up to 24 hours before baking. Great for entertaining or holiday meals.

What protein can I use instead of beef?
Ground turkey or chicken both work well if you’re after a leaner option. Want it meatless? Try plant-based ground crumbles.

Do picky eaters like it?
As long as you don’t mention the green beans up front, you’re in the clear. Cheese and fried onions usually win ’em over.
