How to Make Hamburger Green Bean Casserole Step-by-Step

Making this incredible casserole is as easy as 1-2-3. Follow these simple steps for a perfect result every time.

  1. Brown the Beef: In a large skillet, cook the ground beef over medium-high heat until it’s no longer pink. Drain off any excess grease.
  2. Mix the Filling: In a large bowl, combine the cooked ground beef, cream of mushroom soup, drained green beans, milk, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Gently stir in half of the crispy fried onions.
  3. Assemble and Bake: Spread the mixture evenly into a 9×13 inch baking dish. Bake in a preheated oven at 350°F (175°C) for 25 minutes, or until the casserole is bubbly.
  4. Add Topping and Finish: Remove the casserole from the oven and sprinkle the remaining crispy fried onions over the top. Return it to the oven and bake for another 5-10 minutes, until the onions are golden brown and crispy.

Pro Tips for the Best Casserole

Want to take your Hamburger Green Bean Casserole to the next level? Here are a few expert tips:

  • Don’t Overmix: When combining the ingredients, stir gently until just combined to keep the green beans intact.
  • Add Cheese: For an extra layer of flavor and gooeyness, stir in a cup of shredded cheddar or Colby Jack cheese with the other ingredients.
  • Fresh is an Option: If you prefer, you can use fresh green beans. Just be sure to blanch them first so they cook through in the oven. For a different but equally delicious weeknight skillet meal, check out our ground beef and spinach skillet.

Fun Variations to Try

A dash of soy sauce can also enhance the umami flavor. If you’re looking for another comforting beef recipe, this meatloaf tater tot casserole is always a hit.

Storing and Reheating Your Casserole

This Hamburger Green Bean Casserole makes for fantastic leftovers. Store any remaining casserole in an airtight container in the refrigerator for up to 4 days. To reheat, you can microwave individual portions or place the entire baking dish back in a 350°F oven until warmed through. Note that the onion topping may lose some of its crispiness upon reheating.
