Ingredients
  

For the casserole
  • Nonstick cooking spray for coating the baking dish
  • 1.5 lb ground beef 85% lean
  • 1 yellow onion medium, diced
  • 2 cloves garlic minced
  • 2 can (10.5 oz) condensed cream of mushroom soup
  • 0.5 cup milk
  • 1 tsp soy sauce
  • 0.5 tsp black pepper
  • 2 bag (12 oz) green beans frozen cut, thawed, drained, and patted dry
For the topping
  • 1 can (6 oz) crispy fried onions

Equipment

  • 1 9x13-inch baking dish
  • 1 12-inch skillet

Method
 

Cook the beef and assemble
  1. Heat the oven to 375°F.
  2. Coat a 9x13-inch baking dish with nonstick cooking spray.
  3. Cook the ground beef and onion in a 12-inch skillet over medium-high heat for 8–10 minutes, breaking up the beef, until the onion is tender and the beef reaches 160°F.
  4. Drain excess fat.
  5. Stir in the garlic and cook for 30 seconds.
  6. Stir in the cream of mushroom soup, milk, soy sauce, and black pepper.
  7. Fold in the green beans and spread the mixture in the prepared baking dish.
Bake and finish
  1. Bake for 25–30 minutes, until the casserole is hot and bubbling at the edges.
  2. Sprinkle the crispy fried onions evenly over the top.
  3. Bake for 5–8 minutes, until golden brown.
  4. Rest the casserole for 10 minutes before serving.

Notes

For the best texture, drain the beef well and pat the thawed green beans dry so the casserole stays thick. Refrigerate leftovers for 3–4 days; freezer: yes, though the crispy onion topping may soften. For a gluten-free version, use gluten-free mushroom soup and crispy fried onions.
