Preparation Phase & Tools to Use
To ensure the best results with your Cheesy Hamburger Green Bean Casserole, start by preheating your oven to 375°F (190°C) and greasing a 9×13-inch baking dish to prevent sticking. Preparing your kitchen is an essential step—make sure you have all your ingredients at hand and your tools ready. You’ll need a large skillet to brown the ground beef, a pot for blanching the green beans, and a mixing bowl for combining your creamy ingredients.
Consider using a sharp knife and cutting board to trim and halve the green beans. This prep work will make your cooking process smoother. Ensure you have measuring cups at the ready for precise measurements of your ingredients like the sour cream and cheddar cheese.

Ingredients
- 1 lb ground beef
- 1 lb fresh green beans, trimmed and halved
- 1 can (10.5 oz) cream of mushroom soup
- 1/2 cup sour cream
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- Salt and black pepper to taste
- 1 1/2 cups shredded cheddar cheese
- 1 1/2 cups crispy fried onions
Instructions
Step 1: Prepare the Oven and Dish
Start by preheating your oven to 375°F (190°C). While the oven warms up, apply a little non-stick spray or grease to your 9×13-inch baking dish. This step is vital as it prevents the casserole from sticking, allowing for easy serving later.
Step 2: Brown the Ground Beef
In a large skillet, over medium heat, add the ground beef. Cook it until it’s thoroughly browned and no longer pink, about 7-10 minutes. Be sure to break up the meat as it cooks for even browning. Once cooked, drain any excess fat for a healthier dish, then season it with garlic powder, onion powder, salt, and black pepper for enhanced flavor.
Step 3: Blanch the Green Beans
In a pot of boiling salted water, add your freshly trimmed green beans and blanch them for 3-4 minutes. This brief cooking process brightens their color and helps maintain their crunch. Afterward, drain and set the beans aside to cool slightly.
Step 4: Combine Ingredients
In a mixing bowl, combine the cream of mushroom soup with the sour cream, creating a creamy blend. Add the cooked ground beef and the blanched green beans, and stir until everything is evenly integrated. This creamy mixture forms the heart of your casserole!
Step 5: Bake the Casserole
Transfer the entire mixture into your pre-greased baking dish, spreading it out to ensure even cooking. The next step is to top this beautifully creamy layer with shredded cheddar cheese, creating a rich, cheesy base for your baking magic. Place the dish in the oven and bake uncovered for 20 minutes.
Step 6: Add the Crispy Topping
After 20 minutes, remove the casserole from the oven. Here’s where the magic continues: sprinkle the crispy fried onions generously over the top. This adds a glorious crunch that contrasts the creamy interior beautifully. Return the casserole to the oven and bake for an additional 5-7 minutes until the onions are golden brown and crispy.
Step 7: Serve and Enjoy
Once baked to perfection, let your Cheesy Hamburger Green Bean Casserole rest for about 5 minutes. This will allow it to set just a little for easier serving. Serve warm and watch as everyone dives into this deliciously cheesy and hearty dish!

Variations
- Protein: Switch up the meat by using ground turkey or chicken for a lighter version.
- Vegetables: Add in sautéed mushrooms or a mix of other vegetables like bell peppers or broccoli for added nutrition.
- Spices: Enhance the flavor with additional spices like paprika or cayenne pepper for a little heat.
